Ciraci, Selim; Daily, Jeffrey A.; Fuller, Jason C.

This paper describes the Fenix framework that uses a federated approach for integrating power grid and communication network simulators. Compared existing approaches, Fenix al- lows co-simulation of both transmission and distribution level power grid simulators with the communication network sim- ulator. To reduce the performance overhead of time synchro- nization, Fenix utilizes optimistic synchronization strategies that make speculative decisions about when the simulators are going to exchange messages. GridLAB-D (a distribution simulator), PowerFlow (a transmission simulator), and ns-3 (a telecommunication simulator) are integrated with the frame- work and are used to illustrate the enhanced performance pro- vided by speculative multi-threadingmore » on a smart grid applica- tion. Our speculative multi-threading approach achieved on average 20% improvement over the existing synchronization methods« less

Green-tree retention in harvest units: Boon or bust for biodiversity?
Jonathan Thompson
2007-01-01
In response to societal concerns about clearcutting in the Pacific Northwest, structural or green-tree retention is now an integral part of harvest prescriptions on federal lands. However, the benefits of different levels or patterns of retention for the ecological, microclimatic, and aesthetic attributes of resulting forest stands remain speculative.

Crude oil prices: Speculation versus fundamentals
NASA Astrophysics Data System (ADS)
Kolodziej, Marek Krzysztof
Beginning in 2004, the price of crude oil fluctuates rapidly over a wide range. Large and rapid price increases have recessionary consequences and dampen long-term infrastructural investment. I investigate whether price changes are driven by market fundamentals or speculation. With regard to market fundamentals, I revisit econometric evidence for the importance of demand shocks, as proxied by dry maritime cargo rates, on oil prices. When I eliminate transportation costs from both sides of the equation, disaggregate OPEC and non-OPEC production, and allow for more than one cointegrating relation, I find that previous specifications are inconsistent with arguments that demand shocks play an important role. Instead, results confirm the importance of OPEC supply shocks. I investigate two channels by which speculation may affect oil prices; the direct effect of trader behavior and changes in oil from a commodity to a financial asset. With regard to trader behavior, I find evidence that trader positions are required to explain the spread between spot and futures prices of crude oil on the New York Mercantile Exchange. The inclusion of trader positions clarifies the process of equilibrium error correction, such that there is bidirectional causality between prices and trader positions. This creates the possibility of speculative bubbles. With regard to oil as a commodity and/or financial asset, I use a Kalman Filter model to estimate the time-varying partial correlation between returns to investments in equity and oil markets. This correlation changes from negative to positive at the onset of the 2008 financial crisis. The low interest rates used to rescue the economy depress convenience yields, which reduces the benefits of holding oil as a commodity. Instead, oil becomes a financial asset (on net) as the oil market changed from contango to backwardation. Contradicting simple political narratives, my research suggests that both market fundamentals and speculation drive large oil prices. Chinese oil demand is not responsible for large increases in oil prices; nor are they caused by behavioral idiosyncrasies by oil traders. Finally, oil will be treated largely as a financial asset so long as interest rates are held near their all-time lows.

A Nonlinear Super-Exponential Rational Model of Speculative Financial Bubbles
NASA Astrophysics Data System (ADS)
Sornette, D.; Andersen, J. V.
Keeping a basic tenet of economic theory, rational expectations, we model the nonlinear positive feedback between agents in the stock market as an interplay between nonlinearity and multiplicative noise. The derived hyperbolic stochastic finite-time singularity formula transforms a Gaussian white noise into a rich time series possessing all the stylized facts of empirical prices, as well as accelerated speculative bubbles preceding crashes. We use the formula to invert the two years of price history prior to the recent crash on the Nasdaq (April 2000) and prior to the crash in the Hong Kong market associated with the Asian crisis in early 1994. These complex price dynamics are captured using only one exponent controlling the explosion, the variance and mean of the underlying random walk. This offers a new and powerful detection tool of speculative bubbles and herding behavior.

Based on the implicit calculus equation modeling approach, this paper proposes a speculative concept of the potential and wave operators on negative dimensionality. Unlike the standard partial differential equation (PDE) modeling, the implicit calculus modeling approach does not require the explicit expression of the PDE governing equation. Instead the fundamental solution of physical problem is used to implicitly define the differential operator and to implement simulation in conjunction with the appropriate boundary conditions. In this study, we conjecture an extension of the fundamental solution of the standard Laplace and Helmholtz equations to negative dimensionality. And then by using the singular boundary method, a recent boundary discretization technique, we investigate the potential and wave problems using the fundamental solution on negative dimensionality. Numerical experiments reveal that the physics behaviors on negative dimensionality may differ on positive dimensionality. This speculative study might open an unexplored territory in research.

The taxation of Canadian oil and gas production has occasioned significant conflict between the federal government and the provinces, which own most of the petroleum resources. During the upheaval of the world oil market in the 1970s, such conflict became overt, with claims and counterclaims on perceived economic rents. In contrast, the 1950s and 1960s had been relatively quiet, with quite straightforward taxation regimes requiring only a little federal-provincial policy coordination. Federal policies were then preoccupied with encouraging market growth, with scant attention to pricing and revenue shares, the issues that have dominated federal and provincial energy policy in themore » 1970s and the 1980s. The authors begin by outlining the tax and royalty systems imposed by the federal government and by the government of Alberta, which accounts for some 85% of Canadian oil and gas output. They use the term system here in a broad sense to include all revenue-collecting devices and direct subsidies. Then they analyze the nature, problems, and efficiency of these regimes, especially as devices to collect economic rent. A final section speculates about the future evolution of Canadian oil and gas taxation. 13 references, 4 tables.« less
Beyond speculative robot ethics: a vision assessment study on the future of the robotic caretaker.
van der Plas, Arjanna; Smits, Martijntje; Wehrmann, Caroline
2010-11-01
In this article we develop a dialogue model for robot technology experts and designated users to discuss visions on the future of robotics in long-term care. Our vision assessment study aims for more distinguished and more informed visions on future robots. Surprisingly, our experiment also led to some promising co-designed robot concepts in which jointly articulated moral guidelines are embedded. With our model, we think to have designed an interesting response on a recent call for a less speculative ethics of technology by encouraging discussions about the quality of positive and negative visions on the future of robotics.

In the debate on the ethics of the non-medical use of pharmaceuticals for cognitive performance enhancement in healthy individuals there is a clear division between those who view "cognitive enhancement" as ethically unproblematic and those who see such practices as fraught with ethical problems. Yet another, more subtle issue, relates to the relevance and quality of the contribution of scholarly bioethics to this debate. More specifically, how have various forms of speculation, anticipatory ethics, and methods to predict scientific trends and societal responses augmented or diminished this contribution? In this paper, we use the discussion of the ethics of cognitive enhancement to explore the positive and negative contribution of speculation in bioethics scholarship. First, we review and discuss how speculation has relied on different sets of assumptions regarding the non-medical use of stimulants, namely: (1) terminology and framing; (2) scientific aspects such as efficacy and safety; (3) estimates of prevalence and consequent normalization; and (4) the need for normative reflection and regulatory guidelines. Second, three methodological guideposts are proposed to alleviate some of the pitfalls of speculation: (1) acknowledge assumptions more explicitly and identify the value attributed to assumptions; (2) validate assumptions with interdisciplinary literature; and (3) adopt a broad perspective to promote more comprehensive reflection. We conclude that, through the examination of the controversy about cognitive enhancement, we can employ these methodological guideposts to enhance the value of contributions from bioethics and minimize potential epistemic and practical pitfalls in this case and perhaps in other areas of bioethical debate.

In this article, I offer a retrospective case study about my early, short-term work within the U.S. Office of the Assistant Secretary for Health and then my later, longer-term work within the U.S. Centers for Disease Control and Prevention, where I endeavored for two decades largely to help our nation's schools improve health and associated education outcomes. First, for context, I briefly portray the nature of our related political and public health systems. I then frame this retrospective by illustrating how my serial employment within other public health system organizations led to, and then resulted from, my work within these two federal public health agencies. To represent the many talented individuals in each organization with whom I had the good fortune to work, I name only one in each organization. I then characterize how these individuals and organizations progressively shaped my work and career. I conclude by speculating about prospects for academic institutions to more purposefully prepare students and faculty to work within federal government public health agencies. © 2016 Society for Public Health Education.

Seismogram offers insight into Oklahoma City bombing
NASA Astrophysics Data System (ADS)
Holzer, Thomas L.; Fletcher, Joe B.; Fuis, Gary S.; Ryberg, Trond; Brocher, Thomas M.; Dietel, Christopher M.
The terrorist bombing of the Alfred P. Murrah Federal Building in Oklahoma City on April 19, 1995, generated seismic waves that were recorded on two permanent seismographs about 7 and 26 km away from the bombing. The seismogram recorded at 26 km shows two low-frequency wave trains, discrete sets of oscillatory signals, that begin about 10 s apart. Public release of this record prompted speculation that each wave train was caused by a different energy source. On May 23, 1995, the U.S. Geological Survey monitored the demolition of the bomb-ravaged Federal Building with portable seismographs (Figure 1). Two wave trains were picked up again. The recordings indicate that the wave trains during both the bombing and demolition represent seismic waves traveling at different velocities. We conclude that the two wave trains recorded during the bombing are consistent with a single impulsive energy source.
Sagebrush Rebellion. [Proposed transfer of 175 million acres of Federal lands to states
DOE Office of Scientific and Technical Information (OSTI.GOV)

1980-01-01
The Sagebrush Rebellion concerns a proposal to transfer 175 million acres of Federally-owned wildlands to state governments, an idea with political appeal for many an opportunity to replace decades of conservation and wilderness planning with development and speculation. The project is seen as a way to grab public lands for private profit, its supporters largely drawn from the group which will gain either financially or politically. The movement grew out of government efforts to cut back on overgrazing on public lands and alert the public to the environmental impacts of grazing policies. Although legislative efforts have not succeeded, the movementmore » has hindered the Bureau of Land Management and has championed private interests to the point where use violations and efforts to discredit government management are flagrant. A concerted lobbying effort is called for to prevent a massive land transfer. (DCK)« less
Checkpointing in speculative versioning caches
Eichenberger, Alexandre E; Gara, Alan; Gschwind, Michael K; Ohmacht, Martin
2013-08-27
Mechanisms for generating checkpoints in a speculative versioning cache of a data processing system are provided. The mechanisms execute code within the data processing system, wherein the code accesses cache lines in the speculative versioning cache. The mechanisms further determine whether a first condition occurs indicating a need to generate a checkpoint in the speculative versioning cache. The checkpoint is a speculative cache line which is made non-speculative in response to a second condition occurring that requires a roll-back of changes to a cache line corresponding to the speculative cache line. The mechanisms also generate the checkpoint in the speculative versioning cache in response to a determination that the first condition has occurred.

A 90-day study was made of teleoperators, robotics, and remote systems technology in the United States. The purpose of the study was to survey state-of-the-art technology in this field, determine major user needs in medicine, mining, and oceanography, and suggest initiatives where federal research and development funding would most significantly impact the application of this technology to the alleviation of explicit national social problems. Following a review of the findings of this study commencing with user needs, speculation is made on impending developments in the application of telemation to remote emergency medical care and remote mining systems.
Benign paroxysmal positional vertigo after use of noise-canceling headphones.
Dan-Goor, Eric; Samra, Monica
2012-01-01
Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo. We describe a case of a woman presenting acutely with a severe episode of disabling positional vertigo. Although she had no known etiologic risk factors, this attack followed 12 hours of continuously wearing digital noise-canceling headphones. This is the first such reported association between BPPV and the use of this gadget. We also provide a short review of BPPV and speculate on the possible pathogenic mechanisms involved.

Telecommunications, health care, and legal liability
NASA Astrophysics Data System (ADS)
Levy, Chris
1990-06-01
Regulation of health care telecommunications is fragmented in Canada. Further neither the legislative nor the administrative nor the judicial processes have managed to respond successfully to the impact of telecommunications technology. The result is a legal environment that is necessarily speculative for both telecommunications service providers and health care personnel and facilities. Critical issues include ensuring confidentiality for sensitive patient records and health information liability of telecommunications service providers for inaccurate transmission liability of health care providers for use or non-use of telecommunications services. Limitation of legal liability for both telecommunications and health care service providers is likely to be most effective when based on contract but the creation of the necessary contracts is potentially unduly cumbersome both legally and practically. 1. CONSTITUTIONAL ASPECTS Telecommunications systems that are empowered to operate or connect cross provincial or international boundaries are subject to federal regulation bu the scheme is incomplete in respect of a system set up as a provincial agency. Health care on the other hand is very much a matter of provincial rather than federal authority as a matter of strict law but the fiscal strength of the federal government enables it to provide money to the provinces for financing health care and to4 use this as a device for securing compliance with certain federal standards. Nevertheless the political willingness of the federal health authorities to impose standards on the provinces
The conceptual and empirical relationship between gambling, investing, and speculation
Arthur, Jennifer N.; Williams, Robert J.; Delfabbro, Paul H.
2016-01-01
Background and aims To review the conceptual and empirical relationship between gambling, investing, and speculation. Methods An analysis of the attributes differentiating these constructs as well as identification of all articles speaking to their empirical relationship. Results Gambling differs from investment on many different attributes and should be seen as conceptually distinct. On the other hand, speculation is conceptually intermediate between gambling and investment, with a few of its attributes being investment-like, some of its attributes being gambling-like, and several of its attributes being neither clearly gambling or investment-like. Empirically, gamblers, investors, and speculators have similar cognitive, motivational, and personality attributes, with this relationship being particularly strong for gambling and speculation. Population levels of gambling activity also tend to be correlated with population level of financial speculation. At an individual level, speculation has a particularly strong empirical relationship to gambling, as speculators appear to be heavily involved in traditional forms of gambling and problematic speculation is strongly correlated with problematic gambling. Discussion and conclusions Investment is distinct from gambling, but speculation and gambling have conceptual overlap and a strong empirical relationship. It is recommended that financial speculation be routinely included when assessing gambling involvement, and there needs to be greater recognition and study of financial speculation as both a contributor to problem gambling as well as an additional form of behavioral addiction in its own right.

A multiprocessor system supports multiple concurrent modes of speculative execution. Speculation identification numbers (IDs) are allocated to speculative threads from a pool of available numbers. The pool is divided into domains, with each domain being assigned to a mode of speculation. Modes of speculation include TM, TLS, and rollback. Allocation of the IDs is carried out with respect to a central state table and using hardware pointers. The IDs are used for writing different versions of speculative results in different ways of a set in a cache memory.

Enhancement: are ethicists excessively influenced by baseless speculations?
Jones, D G
2006-12-01
Most commentators draw a sharp distinction between therapy and enhancement, applauding therapy and rejecting enhancement. Not only is this distinction unclear but enhancement is often seen in grandiose terms in which human beings are radically transformed. Such far-reaching visions are then used to reject current procedures such as pre-implantation genetic diagnosis. To overcome this highly problematic impasse, enhancement has been divided into three categories, ranging from the health-related enhancement of category 1, through the non-health-related enhancement of category 2, to the transhumanism or posthumanism of category 3. Arguably, most enhancements are of the category 1 variety, and hence closely related to treatment. Also, we are already enhanced, when compared with our forebears. It is only when we accept this and dispense with baseless speculation will we be in a position to conduct ethical discussions within a realistic framework.

A rational speculative bubble is a surge in asset prices that exceed its intrinsic value. Rational speculative bubbles are among the ascription which may lead to the collapse of an economic system. Rational speculative bubble cannot be created but it comes into existence when assets started to be traded. Financial rational speculative bubble and burst have negative effect on the economy and markets. Financial rational speculative bubbles are difficult to detect. This study aims to shows the size of rational speculative bubble in four markets, which are gold, Hang Seng, S&P500 and Nikkei 225 during year 2008 to 2016. In this study, generalized Johansen-Ledoit-Sornette model are used to find the size of the rational speculative bubble. Bubble detection is important for both sides of macro-economic decision makers and to the trader. Especially for a trading system that requires detailed knowledge about the time and the stage of the bubble burst.

Connecting the obesity and the narcissism epidemics.
Lemaitre, Bruno
2016-10-01
Obesity and metabolic syndromes are major threats to health in both developed and developing countries. This opinion article is a holistic attempt to understand the obesity epidemic, by connecting it to the widespread narcissism in society. The narcissism epidemic refers to an increased prevalence of status-striving individualism and a decreased sense of community, observed in Westerns populations and spreading worldwide. Based on social personality and evolutionary psychology approaches, I speculate that this rise of narcissism underlies a steep social hierarchy resulting in increase of social stress. This social stress markedly affects individuals who are sensitive to social hierarchy dominance due to their personality, yet are relegated at a lower social position. I speculate that over-eating is one major mechanism for coping with this stress, and discuss the possibility that visceral fat may constitute an adaptive behaviour to the lower social hierarchy position, which is perceived as unjust. Connecting the prevalence of obesity to the narcissism epidemic allows for a more thorough examination of factors, which contribute to obesity, which includes early difficult childhood experience, lower rank, and the overall competitive framework of the society.

After months of speculation about funding for science in the Fiscal Year 1998 (FY 1998) federal budget, some first figures became available in late June for the National Science Foundation and NASA—when the House of Representatives' VA, HUD, Independent Agencies Appropriations Subcommittee marked up its bill. However, details may not be known until July 8, when the full House Appropriations Committee meets to vote on the legislation. The full House is expected to vote on the appropriations the week of July 13. The Senate Appropriations Subcommittee, which has less overall money to spend, is expected to complete its work the week of July 13 also. The following information is known about the House bill.
Speculation and replication in temperature accelerated dynamics
Zamora, Richard J.; Perez, Danny; Voter, Arthur F.
2018-02-12
Accelerated Molecular Dynamics (AMD) is a class of MD-based algorithms for the long-time scale simulation of atomistic systems that are characterized by rare-event transitions. Temperature-Accelerated Dynamics (TAD), a traditional AMD approach, hastens state-to-state transitions by performing MD at an elevated temperature. Recently, Speculatively-Parallel TAD (SpecTAD) was introduced, allowing the TAD procedure to exploit parallel computing systems by concurrently executing in a dynamically generated list of speculative future states. Although speculation can be very powerful, it is not always the most efficient use of parallel resources. In this paper, we compare the performance of speculative parallelism with a replica-based technique, similarmore » to the Parallel Replica Dynamics method. A hybrid SpecTAD approach is also presented, in which each speculation process is further accelerated by a local set of replicas. Finally and overall, this work motivates the use of hybrid parallelism whenever possible, as some combination of speculation and replication is typically most efficient.« less

[Testing a Model to Predict Problem Gambling in Speculative Game Users].
Park, Hyangjin; Kim, Suk Sun
2018-04-01
The purpose of the study was to develop and test a model for predicting problem gambling in speculative game users based on Blaszczynski and Nower's pathways model of problem and pathological gambling. The participants were 262 speculative game users recruited from seven speculative gambling places located in Seoul, Gangwon, and Gyeonggi, Korea. They completed a structured self-report questionnaire comprising measures of problem gambling, negative emotions, attentional impulsivity, motor impulsivity, non-planning impulsivity, gambler's fallacy, and gambling self-efficacy. Structural Equation Modeling was used to test the hypothesized model and to examine the direct and indirect effects on problem gambling in speculative game users using SPSS 22.0 and AMOS 20.0 programs. The hypothetical research model provided a reasonable fit to the data. Negative emotions, motor impulsivity, gambler's fallacy, and gambling self-efficacy had direct effects on problem gambling in speculative game users, while indirect effects were reported for negative emotions, motor impulsivity, and gambler's fallacy. These predictors explained 75.2% problem gambling in speculative game users. The findings suggest that developing intervention programs to reduce negative emotions, motor impulsivity, and gambler's fallacy, and to increase gambling self-efficacy in speculative game users are needed to prevent their problem gambling. © 2018 Korean Society of Nursing Science.

In a multiprocessor system, a conflict checking mechanism is implemented in the L2 cache memory. Different versions of speculative writes are maintained in different ways of the cache. A record of speculative writes is maintained in the cache directory. Conflict checking occurs as part of directory lookup. Speculative versions that do not conflict are aggregated into an aggregated version in a different way of the cache. Speculative memory access requests do not go to main memory.

We report a rare finding of two male breast cancer patients with HER2-positive breast cancer who also developed thyroid cancer. We reviewed 45 male breast cancer patients treated in our institution from 2003 to 2008. Only five male breast cancer patients were HER2-positive. In reviewing the published data, we found no cases of thyroid cancer and concurrent breast cancer in men. However, breast cancer and thyroid cancer have shown close association in women. This finding therefore provokes speculation as to whether we should investigate whether women with HER2-positive breast cancer are at a higher risk for thyroid cancer. Although this observation seems to be clinically prevalent, publications are sparse in clinical research areas linking thyroid cancer to breast cancer.

The Town Meeting on Plasma Physics at the National Science Foundation will provide an opportunity for Q&A about the variety of NSF programs and solicitations relevant to a broad cross-section of the academic plasma science community, from graduating college seniors to senior leaders in the field, and from plasma astrophysics to basic physics to plasma engineering communities. We will discuss recent NSF-hosted events, research awards, and multi-agency partnerships aimed at enabling the progress of science in plasma science and engineering. Future outlook for plasma physics and broader plasma science support at NSF, with an emphasis on how you can help NSF to help the community, will be speculated upon within the uncertainty of the federal budgeting process.
How to attract young people to science? (based on materials of sociological research)
NASA Astrophysics Data System (ADS)
Karpov, D. A.; Karpova, A. Yu; Kryuchkov, Yu Yu
2015-10-01
Involvement of young people into science at the present time is relevant not only in Russia but as well in countries with big experience in this process. The article states that profession of scientist is considered prestigious in the United States and positioned at 4th place in the rating, wheras in Russia it is only at 19th place in the similar rating. The conclusion is based on the sociological studies conducted in the United States and Russia. The authors speculate that changes in public policy in Russia, aimed at recovering of scientific potential, had an impact on young people's ideas and motivation for scientific work. The article provides an analysis of the sociological study conducted by the National Research Tomsk Polytechnic University (TPU), which aims to determine the willingness and possibility to engage in scientific work. The authors note that TPU entered the federal program “5-100-2020” at 4th place in the ranking of the best universities in Russia and has extensive experience, research base, international training programs, exchanges, and internships with best universities in the United States and Europe. The main conclusions of the study is that master students are ready to engage in scientific work; conditions created at the university are the backbone for the development of scientific career of the students; the highest motivation for students is the satisfaction in their scientific advisors.
Speculation detection for Chinese clinical notes: Impacts of word segmentation and embedding models.
Zhang, Shaodian; Kang, Tian; Zhang, Xingting; Wen, Dong; Elhadad, Noémie; Lei, Jianbo
2016-04-01
Speculations represent uncertainty toward certain facts. In clinical texts, identifying speculations is a critical step of natural language processing (NLP). While it is a nontrivial task in many languages, detecting speculations in Chinese clinical notes can be particularly challenging because word segmentation may be necessary as an upstream operation. The objective of this paper is to construct a state-of-the-art speculation detection system for Chinese clinical notes and to investigate whether embedding features and word segmentations are worth exploiting toward this overall task. We propose a sequence labeling based system for speculation detection, which relies on features from bag of characters, bag of words, character embedding, and word embedding. We experiment on a novel dataset of 36,828 clinical notes with 5103 gold-standard speculation annotations on 2000 notes, and compare the systems in which word embeddings are calculated based on word segmentations given by general and by domain specific segmenters respectively. Our systems are able to reach performance as high as 92.2% measured by F score. We demonstrate that word segmentation is critical to produce high quality word embedding to facilitate downstream information extraction applications, and suggest that a domain dependent word segmenter can be vital to such a clinical NLP task in Chinese language.

Data-dependence Profiling to Enable Safe Thread Level Speculation
DOE Office of Scientific and Technical Information (OSTI.GOV)
Bhattacharyya, Arnamoy; Amaral, José Nelson; Finkel, Hal
Data-dependence profling is a technique that enables a com- piler to judiciously decide when the execution of a loop | which the compiler could not prove to be dependence free | should be speculated through the use of Thread Level Spec- ulation (TLS). The data collected by a data-dependence pro- fler can be used to predict if may dependencies reported by a compiler static analysis are likely to materialize at runtime. A cost analysis can then be used to decide that some loops with a lower probability of dependence should be specula- tively parallelized. This paper addresses the question asmore » to whether a loops' dependence behaviour changes when the in- put to the program changes | a study of 57 different bench- marks indicates that it usually does not change. Then the paper describes SpecEval, an automatic speculative paral- lelization framework that uses single-input data-dependence profles to find speculation candidates in the SPEC2006 and PolyBench/C benchmarks. This paper also presents a per- formance evaluation of TLS implementation in IBM's Blue- Gene/Q supercomputer and shows that the performance of TLS is affected by several factors, including the number of speculated loops, the execution-time coverage of speculated loops, the miss-speculation overhead, the L1 cache miss rate and the effect on dynamic instruction path length.« less

Early stages in the biogenesis of eukaryotic β-barrel proteins.
Jores, Tobias; Rapaport, Doron
2017-09-01
The endosymbiotic organelles mitochondria and chloroplasts harbour, similarly to their prokaryotic progenitors, β-barrel proteins in their outer membrane. These proteins are encoded on nuclear DNA, translated on cytosolic ribosomes and imported into their target organelles by a dedicated machinery. Recent studies have provided insights into the import into the organelles and the membrane insertion of these proteins. Although the cytosolic stages of their biogenesis are less well defined, it is speculated that upon their synthesis, chaperones prevent β-barrel proteins from aggregation and keep them in an import-competent conformation. In this Review, we summarize the current knowledge about the biogenesis of β-barrel proteins, focusing on the early stages from the translation on cytosolic ribosomes to the recognition on the surface of the organelle. © 2017 Federation of European Biochemical Societies.

In a multiprocessor system with at least two levels of cache, a speculative thread may run on a core processor in parallel with other threads. When the thread seeks to do a write to main memory, this access is to be written through the first level cache to the second level cache. After the write though, the corresponding line is deleted from the first level cache and/or prefetch unit, so that any further accesses to the same location in main memory have to be retrieved from the second level cache. The second level cache keeps track of multiple versions of data, where more than one speculative thread is running in parallel, while the first level cache does not have any of the versions during speculation. A switch allows choosing between modes of operation of a speculation blind first level cache.
Version pressure feedback mechanisms for speculative versioning caches
Eichenberger, Alexandre E.; Gara, Alan; O& #x27; Brien, Kathryn M.; Ohmacht, Martin; Zhuang, Xiaotong
2013-03-12
Mechanisms are provided for controlling version pressure on a speculative versioning cache. Raw version pressure data is collected based on one or more threads accessing cache lines of the speculative versioning cache. One or more statistical measures of version pressure are generated based on the collected raw version pressure data. A determination is made as to whether one or more modifications to an operation of a data processing system are to be performed based on the one or more statistical measures of version pressure, the one or more modifications affecting version pressure exerted on the speculative versioning cache. An operation of the data processing system is modified based on the one or more determined modifications, in response to a determination that one or more modifications to the operation of the data processing system are to be performed, to affect the version pressure exerted on the speculative versioning cache.
Insertion of operation-and-indicate instructions for optimized SIMD code
Eichenberger, Alexander E; Gara, Alan; Gschwind, Michael K
2013-06-04
Mechanisms are provided for inserting indicated instructions for tracking and indicating exceptions in the execution of vectorized code. A portion of first code is received for compilation. The portion of first code is analyzed to identify non-speculative instructions performing designated non-speculative operations in the first code that are candidates for replacement by replacement operation-and-indicate instructions that perform the designated non-speculative operations and further perform an indication operation for indicating any exception conditions corresponding to special exception values present in vector register inputs to the replacement operation-and-indicate instructions. The replacement is performed and second code is generated based on the replacement of the at least one non-speculative instruction. The data processing system executing the compiled code is configured to store special exception values in vector output registers, in response to a speculative instruction generating an exception condition, without initiating exception handling.
Stellar Stream Candidates in the Solar Neighborhood Found in the LAMOST DR3 and TGAS

We have cross-matched the LAMOST DR3 with the Gaia DR1 TGAS catalogs and obtained a sample of 166,827 stars with reliable kinematics. A technique based on the wavelet transform was applied to detect significant overdensities in velocity space among five subsamples divided by spatial position. In total, 16 significant overdensities of stars with very similar kinematics were identified. Among these, four are new stream candidates and the rest are previously known groups. Both the U-V velocity and metallicity distributions of the local sample show a clear gap between the Hercules structure and the Hyades-Pleiades structure. The U-V positions of these peaks shift with the spatial position. Following a description of our analysis, we speculate on possible origins of our stream candidates.

Red Shifts and Existing Speculations
NASA Astrophysics Data System (ADS)
Aisenberg, Sol
2009-03-01
There are many current flaws, mysteries, and errors in the standard model of the universe - all based upon speculative interpretation of many excellent and verified observations. The most serious cause of some errors is the speculation about the meaning of the redshifts observed in the 1930s by Hubble. He ascribed the redshifts as due to ``an apparent Doppler effect''. This led to speculation that the remote stars were receding, and the universe was expanding -- although without observational proof of the actual receding velocity of the stars. The age of the universe, based upon the Hubble constant is pure speculation because of lack of velocity demonstration. The belief in expansion, the big bang, and of inflation should be reexamined. Also, the redshift cannot always be used as a distance measure, particularly for photons from quasars containing massive black holes that can reduce photon energy through gravitational attraction. If the linear Hubble constant is extrapolated to the most remote super novae and beyond, it would eventually require that the corresponding photon energy go to zero or become negative -- according to Hubble linear relationship. This should require a reexamination of the meaning of the red shift and the speculative consequences and give a model with fewer mysteries.

Potential impact of HITECH security regulations on medical imaging.
Prior, Fred; Ingeholm, Mary Lou; Levine, Betty A; Tarbox, Lawrence
2009-01-01
Title XIII of Division A and Title IV of Division B of the American Recovery and Reinvestment Act (ARRA) of 2009 [1] include a provision commonly referred to as the "Health Information Technology for Economic and Clinical Health Act" or "HITECH Act" that is intended to promote the electronic exchange of health information to improve the quality of health care. Subtitle D of the HITECH Act includes key amendments to strengthen the privacy and security regulations issued under the Health Insurance Portability and Accountability Act (HIPAA). The HITECH act also states that "the National Coordinator" must consult with the National Institute of Standards and Technology (NIST) in determining what standards are to be applied and enforced for compliance with HIPAA. This has led to speculation that NIST will recommend that the government impose the Federal Information Security Management Act (FISMA) [2], which was created by NIST for application within the federal government, as requirements to the public Electronic Health Records (EHR) community in the USA. In this paper we will describe potential impacts of FISMA on medical image sharing strategies such as teleradiology and outline how a strict application of FISMA or FISMA-based regulations could have significant negative impacts on information sharing between care providers.
Two Essays in Financial Economics
NASA Astrophysics Data System (ADS)
Putnam, Kyle J.
The following dissertation contains two distinct empirical essays which contribute to the overall field of Financial Economics. Chapter 1, entitled "The Determinants of Dynamic Dependence: An Analysis of Commodity Futures and Equity Markets," examines the determinants of the dynamic equity-commodity return correlations between five commodity futures sub-sectors (energy, foods and fibers, grains and oilseeds, livestock, and precious metals) and a value-weighted equity market index (S&P 500). The study utilizes the traditional DCC model, as well as three time-varying copulas: (i) the normal copula, (ii) the student's t copula, and (iii) the rotated-gumbel copula as dependence measures. Subsequently, the determinants of these various dependence measures are explored by analyzing several macroeconomic, financial, and speculation variables over different sample periods. Results indicate that the dynamic equity-commodity correlations for the energy, grains and oilseeds, precious metals, and to a lesser extent the foods and fibers, sub-sectors have become increasingly explainable by broad macroeconomic and financial market indicators, particularly after May 2003. Furthermore, these variables exhibit heterogeneous effects in terms of both magnitude and sign on each sub-sectors' equity-commodity correlation structure. Interestingly, the effects of increased financial market speculation are found to be extremely varied among the five sub-sectors. These results have important implications for portfolio selection, price formation, and risk management. Chapter 2, entitled, "US Community Bank Failure: An Empirical Investigation," examines the declining, but still pivotal role, of the US community banking industry. The study utilizes survival analysis to determine which accounting and macroeconomic variables help to predict community bank failure. Federal Deposit Insurance Corporation and Federal Reserve Bank data are utilized to compare 452 community banks which failed between 2000 and 2013, relative to a sample of surviving community banks. Empirical results indicate that smaller banks are less likely to fail than their larger community bank counterparts. Additionally, several unique bank-specific indicators of failure emerge which relate to asset quality and liquidity, as well as earnings ratios. Moreover, results show that the use of the macroeconomic indicator of liquidity, the TED spread, provides a substantial improvement in modeling predictive community bank failure.

No guidelines exist for assessment of aetiology of intellectual disability in adults with intellectual disability by adult physicians, although robust guidelines exist for paediatric populations. It was speculated that the paediatric guidelines would also be suitable for adults. In rural/regional setting with limited clinical genetics, to perform a quality assurance evaluation on genetics assessment of aetiology of developmental disability in adults attending a dedicated healthcare clinic for adults with intellectual disability, compared results with paediatric standards, speculates if these seem appropriate for adults and speculates on a role for clinical genetics services. Retrospective chart audit of eligible patients looking at genetic clinical assessment, tests selected (molecular karyotype, G banding, metabolics), and yields of positive results. The results were compared with the recommended paediatric guidelines. Of 117 eligible adult patients, ideal genetic history was incomplete for 40% of patients without Down syndrome because of physician cause and lack of information. The number of abnormal genetic results increased from 46% to 66%, mainly from the molecular karyotype, though not all may have been clinically relevant. The improved yield from this test was similar to that in paediatric studies. Use of G banding and metabolic testing could be refined. Improvement can be made in clinical genetic assessment, but results generally support use of molecular karyotyping as first tier testing of cause of unknown intellectual disability in adults, as in the case for paediatric populations. The study highlights a necessary complementary role for clinical geneticists to interpret abnormal results. © 2016 Royal Australasian College of Physicians.

How solutes and macromolecules are removed from brain tissue is of central importance in normal brain physiology and in how toxic protein aggregates are cleared in neurodegenerative conditions, including Alzheimer's disease (AD). Conventionally, solute transport in the narrow and tortuous extracellular space in brain parenchyma has been thought to be primarily diffusive and nondirectional. The recently proposed "glymphatic" (glial-lymphatic) hypothesis posits that solute clearance is convective and driven by active fluid transport from para-arterial to paravenous spaces though aquaporin-4 water channels in astrocyte endfeet. Glymphatic, convective solute clearance has received much attention because of its broad implications for AD and other brain pathologies and even the function of sleep. However, the theoretical plausibility of glymphatic transport has been questioned, and recent data have challenged its experimental underpinnings. A substantiated mechanism of solute clearance in the brain is of considerable importance because of its implications for pathogenic mechanisms of neurologic diseases and delivery of therapeutics.-Smith, A. J., Verkman, A. S. The "glymphatic" mechanism for solute clearance in Alzheimer's disease: game changer or unproven speculation?
Near-death experiences between science and prejudice.
Facco, Enrico; Agrillo, Christian
2012-01-01
Science exists to refute dogmas; nevertheless, dogmas may be introduced when undemonstrated scientific axioms lead us to reject facts incompatible with them. Several studies have proposed psychobiological interpretations of near-death experiences (NDEs), claiming that NDEs are a mere byproduct of brain functions gone awry; however, relevant facts incompatible with the ruling physicalist and reductionist stance have been often neglected. The awkward transcendent look of NDEs has deep epistemological implications, which call for: (a) keeping a rigorously neutral position, neither accepting nor refusing anything a priori; and (b) distinguishing facts from speculations and fallacies. Most available psychobiological interpretations remain so far speculations to be demonstrated, while brain disorders and/or drug administration in critical patients yield a well-known delirium in intensive care and anesthesia, the phenomenology of which is different from NDEs. Facts can be only true or false, never paranormal. In this sense, they cannot be refused a priori even when they appear implausible with respect to our current knowledge: any other stance implies the risk of turning knowledge into dogma and the adopted paradigm into a sort of theology.

Fearless versus fearful speculative financial bubbles
NASA Astrophysics Data System (ADS)
Andersen, J. V.; Sornette, D.
2004-06-01
Using a recently introduced rational expectation model of bubbles, based on the interplay between stochasticity and positive feedbacks of prices on returns and volatility, we develop a new methodology to test how this model classifies nine time series that have been previously considered as bubbles ending in crashes. The model predicts the existence of two anomalous behaviors occurring simultaneously: (i) super-exponential price growth and (ii) volatility growth, that we refer to as the “fearful singular bubble” regime. Out of the nine time series, we find that five pass our tests and can be characterized as “fearful singular bubbles”. The four other cases are the information technology Nasdaq bubble and three bubbles of the Hang Seng index ending in crashes in 1987, 1994 and 1997. According to our analysis, these four bubbles have developed with essentially no significant increase of their volatility. This paper thus proposes that speculative bubbles ending in crashes form two groups hitherto unrecognized, namely those accompanied by increasing volatility (reflecting increasing risk perception) and those without change of volatility (reflecting an absence of risk perception).

The development of Cordilleran orogen of western North American is disputed despite a century of study. Paleomagnetic observations require large-scale dextral displacement of crustal fragments along the western margin of North America, from low latitudes to moderate latitudes during the Cretaceous-Paleogene. A lack of corroborating geological evidence for large-scale displacements has prevented the widespread integration of paleomagnetic data into contemporary tectonic models for the margin. Here we investigate the Cretaceous paleogeographic position of the Baja-BC block, a crustal fragment consisting of the Alexander and Wrangel terranes, using detrital zircons from the Nanaimo Basin of Vancouver Island, British Columbia. We compare 4310 detrital zircon U/Pb analyses from 16 samples to potential source areas in western North America to test hypothesized northern and southern paleogeographic positions. Our detrital zircon data suggest that sediment in the Nanaimo Basin derives from the Mojave-Sonoran Region of southwestern North America, supporting a southerly late Cretaceous paleogeographic position. We present a speculative Cretaceous to Paleogene paleogeographic reconstruction for the southwestern United States and northern Mexico that accommodates the presence, and northward transport, of the Baja-BC block. We propose that the Western Coast Mountains Batholith and the Nanaimo Basin represent the missing segment of the Mesozoic magmatic arc and associated forearc regions, between the Sierra Nevada and Peninsular Ranges Batholiths. This segment was translated northward following capture by the Kula plate. As such, we reconcile the paleomagnetic data for the Baja-BC block with the geology of the southwestern United States. Our model, albeit speculative, is compatible with the large-scale tectonic and magmatic processes that affected western North America in the Late Cretaceous and Paleogene.

In real-time image processing, an application must satisfy a set of timing constraints while ensuring the semantic correctness of the system. Because of the natural structure of digital data, pure data and task parallelism have been used extensively in real-time image processing to accelerate the handling time of image data. These types of parallelism are based on splitting the execution load performed by a single processor across multiple nodes. However, execution of all parallel threads is mandatory for correctness of the algorithm. On the other hand, speculative execution is an optimistic execution of part(s) of the program based on assumptions on program control flow or variable values. Rollback may be required if the assumptions turn out to be invalid. Speculative execution can enhance average, and sometimes worst-case, execution time. In this paper, we target various image processing techniques to investigate applicability of speculative execution. We identify opportunities for safe and profitable speculative execution in image compression, edge detection, morphological filters, and blob recognition.
Predicting bias in perceived position using attention field models.
Klein, Barrie P; Paffen, Chris L E; Pas, Susan F Te; Dumoulin, Serge O
2016-05-01
Attention is the mechanism through which we select relevant information from our visual environment. We have recently demonstrated that attention attracts receptive fields across the visual hierarchy (Klein, Harvey, & Dumoulin, 2014). We captured this receptive field attraction using an attention field model. Here, we apply this model to human perception: We predict that receptive field attraction results in a bias in perceived position, which depends on the size of the underlying receptive fields. We instructed participants to compare the relative position of Gabor stimuli, while we manipulated the focus of attention using exogenous cueing. We varied the eccentric position and spatial frequency of the Gabor stimuli to vary underlying receptive field size. The positional biases as a function of eccentricity matched the predictions by an attention field model, whereas the bias as a function of spatial frequency did not. As spatial frequency and eccentricity are encoded differently across the visual hierarchy, we speculate that they might interact differently with the attention field that is spatially defined.

Wealth in Middle and Old Age in Mexico: The Role of International Migration1
Wong, Rebeca; Palloni, Alberto; Soldo, Beth J.
2017-01-01
This article examines the impact that past migration to the U.S. has on the current economic well-being of individuals in middle or old age who have returned to Mexico. A priori, the net effect of U.S. migration on wealth among return migrants is difficult to predict; there are counteracting factors that can affect wealth positively or negatively. Using data from the Mexican Health and Aging Study 2001 and correcting for selection factors, the long-term effect of U.S. migration for return migrants was found consistently positive in terms of their accumulated personal wealth at middle and old age. This article speculates about the possible mechanisms that can explain this apparent advantage. PMID:29375172
Freud's metapsychological speculations.
Fulgencio, Leopoldo
2005-02-01
In this paper, the author seeks to analyse the nature and function of metapsychological theory in Freudian psychoanalysis. He shows that Freudian psychoanalytic theory is composed of an empirical part--the psychology of clinical facts--and a speculative part--metapsychology. Freud considers this latter part as being a speculative superstructure of value that is only heuristic, capable of being supplanted by other superstructures of the same type. The author sustains the idea that this metapsychology is the fruit of speculative method, whose foundations were elaborated by philosophers and epistemologists before Freud, including Immanuel Kant and Ernst Mach. He concludes with considerations regarding the future of metapsychological theorisation, presenting criticisms of Freudian metapsychology offered by both philosophers and psychoanalysts, and pointing to the perspective opened by Donald W. Winnicott of a psychoanalysis without metapsychology.

Gambling and speculation which leads to zero-sum outcomes are prohibited in Islamic finance and condemned in conventional finance. This article explores the reasons for the similarity of objections towards gambling and speculation. Three probable reasons are explored namely the concept of stewardship in conventional thought and the concept of khalifa in Islam, Christianity and morality's influence on conventional law and finance and the concept of ethics of sacrifice and ethics of tolerance.
Psychology in cognitive science: 1978-2038.
Gentner, Dedre
2010-07-01
This paper considers the past and future of Psychology within Cognitive Science. In the history section, I focus on three questions: (a) how has the position of Psychology evolved within Cognitive Science, relative to the other disciplines that make up Cognitive Science; (b) how have particular Cognitive Science areas within Psychology waxed or waned; and (c) what have we gained and lost. After discussing what's happened since the late 1970s, when the Society and the journal began, I speculate about where the field is going. Copyright © 2010 Cognitive Science Society, Inc.
More on Darwin's illness: comment on the final diagnosis of Charles Darwin.
Sheehan, William; Meller, William H; Thurber, Steven
2008-06-20
Without the possibility of confirmatory exhumation, diagnostic inferences about Darwin's illness must remain speculative. A diagnosis of Darwin's aggregate symptoms must account for not only gastrointestinal distress but also his predominant and excessive retching and the conglomerate of other heterogeneous symptoms. We opine that Crohn's disease, posited as the 'final diagnosis', is not sufficient for subsuming his pleiomorphic symptomatology. An additional proposal is outlined that may help to explain his presentation with heterogeneous symptoms. It incorporates constitutional vulnerabilities, psychosomatic influences and Pavlovian conditioning as explanatory variables.

Cutaneous sporotrichosis, also known as "Rose Gardener's disease," caused by dimorphic fungus Sporothrix schenkii, is usually characterized by indolent nodular or nodulo-ulcerative lesions arranged in a linear pattern. We report bizarre nonlinear presentation of Sporotrichosis, in an immunocompetent adult occurring after a visit to Amazon rain forest, speculating infection with more virulent species of Sporothrix. The diagnosis was reached with the help of periodic acid-Schiff positive yeast cells and cigar shaped bodies seen in skin biopsy along with the therapeutic response to potassium iodide.

Freeze or flee? Negative stimuli elicit selective responding.
Estes, Zachary; Verges, Michelle
2008-08-01
Humans preferentially attend to negative stimuli. A consequence of this automatic vigilance for negative valence is that negative words elicit slower responses than neutral or positive words on a host of cognitive tasks. Some researchers have speculated that negative stimuli elicit a general suppression of motor activity, akin to the freezing response exhibited by animals under threat. Alternatively, we suggest that negative stimuli only elicit slowed responding on tasks for which stimulus valence is irrelevant for responding. To discriminate between these motor suppression and response-relevance hypotheses, we elicited both lexical decisions and valence judgments of negative words and positive words. Relative to positive words (e.g., kitten), negative words (e.g., spider) elicited slower lexical decisions but faster valence judgments. Results therefore indicate that negative stimuli do not cause a generalized motor suppression. Rather, negative stimuli elicit selective responding, with faster responses on tasks for which stimulus valence is response-relevant.
Monaural Sound Localization Based on Structure-Induced Acoustic Resonance
Kim, Keonwook; Kim, Youngwoong
2015-01-01
A physical structure such as a cylindrical pipe controls the propagated sound spectrum in a predictable way that can be used to localize the sound source. This paper designs a monaural sound localization system based on multiple pyramidal horns around a single microphone. The acoustic resonance within the horn provides a periodicity in the spectral domain known as the fundamental frequency which is inversely proportional to the radial horn length. Once the system accurately estimates the fundamental frequency, the horn length and corresponding angle can be derived by the relationship. The modified Cepstrum algorithm is employed to evaluate the fundamental frequency. In an anechoic chamber, localization experiments over azimuthal configuration show that up to 61% of the proper signal is recognized correctly with 30% misfire. With a speculated detection threshold, the system estimates direction 52% in positive-to-positive and 34% in negative-to-positive decision rate, on average. PMID:25668214

A multidimensional Life Stress Model was used to test the independent contributions of background characteristics, personal resources, life event, and environmental influences on 200 widowers' levels of well-being, measured by the Affect Balance Scale. Stepwise regression analyses revealed that environmental resources were unrelated to negative affect which is influenced more by the life event and personal resource variables. The environmental resource variables, particularly interactions with friends and neighbors, mostly influenced positive affect. The explanatory model for well-being included multiple variables and explained 33 percent of the variance. Although background characteristics had the greatest impact, absence of hospitalization, higher mastery, higher self-esteem, contacts with friends, and interaction with neighbors enhanced well-being. The results support previous speculations on the importance of positive exchanges for positive affect. African-American widowers showed higher levels of well-being than Caucasian widowers did. The results advance knowledge about differences among elderly men.
Position-dependent hearing in three species of bushcrickets (Tettigoniidae, Orthoptera)
Lakes-Harlan, Reinhard; Scherberich, Jan
2015-01-01
A primary task of auditory systems is the localization of sound sources in space. Sound source localization in azimuth is usually based on temporal or intensity differences of sounds between the bilaterally arranged ears. In mammals, localization in elevation is possible by transfer functions at the ear, especially the pinnae. Although insects are able to locate sound sources, little attention is given to the mechanisms of acoustic orientation to elevated positions. Here we comparatively analyse the peripheral hearing thresholds of three species of bushcrickets in respect to sound source positions in space. The hearing thresholds across frequencies depend on the location of a sound source in the three-dimensional hearing space in front of the animal. Thresholds differ for different azimuthal positions and for different positions in elevation. This position-dependent frequency tuning is species specific. Largest differences in thresholds between positions are found in Ancylecha fenestrata. Correspondingly, A. fenestrata has a rather complex ear morphology including cuticular folds covering the anterior tympanal membrane. The position-dependent tuning might contribute to sound source localization in the habitats. Acoustic orientation might be a selective factor for the evolution of morphological structures at the bushcricket ear and, speculatively, even for frequency fractioning in the ear. PMID:26543574

A case of false-negative serum latex agglutination cryptococcal antigen (CRAG) test in a 45-year-old HIV-positive male with Cryptococcus-positive culture is described. The patient was presented to a hospital in Botswana, with breathlessness and a diffuse papular rash. His CD4 count was 25 cells/μL. Despite the suspicion for disseminated cryptococcal disease, an initial serum CRAG latex test was negative. Results of subsequent Indian ink staining, culture of cerebrospinal fluid and skin scrapings, and serum lateral flow immunoassay (LFA) were all positive for Cryptococcus neoformans. There are several possible explanations for the false-negative CRAG latex test. Given the positive LFA result, we speculate that disease may have been caused by Cryptococcus gattii, which is estimated to be responsible for between 15% and 30% of all cryptococcal diseases in Botswana. Reduced sensitivity of CRAG latex assays for detecting C gattii may lead to underdiagnosis of cryptococcal infection. © The Author(s) 2014.

This is the third part of a 3-part examination of what may potentially be expected from the 2010 national health care reform legislation. Political researchers and pundits have speculated endlessly on the many changes mandated by the 2010 national health care reform legislation, styled the Patient Protection and Affordable Care Act. A review and assessment of this legislation at several levels (federal, state, state agency, local region, and individual business leaders) were undertaken. The results of this expanded analysis suggest strongly that nationally members of the business community and their employees will benefit from the legislation early on (years 1 through 3) and then likely will be impacted adversely as the payment mechanisms driving the legislation are tightened by new federal regulations (years 4 onward). As a result of this research, it is surmised that businesses will be immediately impacted by the legislation, with small business owners being the prime beneficiaries of the new legislation, owing to the availability of coverage to approximately 32 million individuals who previously had no access to coverage. In that regard, the soon-to-be newly insured population also will be a prime beneficiary of the legislation as the limitations on chronic illnesses and other preexisting conditions will be reduced or eliminated by the legislation.

In December 2010, the United Nations Food and Agriculture Organization's Food Price Index surpassed its previous peak of June 2008, and prices remained at this level through September 2011. This pattern is creating justified fears of a renewal or intensification of the global food crisis. This paper reviews arguments and evidence to inform debates on how to regulate commodity futures markets in the face of such price volatility and sustained high prices. We focus on the relationship between market liquidity and price patterns in asset markets in general and in commodities futures markets in particular, as well as the relationship between spot and futures market prices for food. We find strong evidence supporting the need to limit huge increases in trading volume on futures markets through regulations. We find that arguments opposing regulation are not supported. We find no support for the claim that liquidity in futures markets stabilizes prices at "fundamental" values or that spot market prices are free of any significant influence from futures markets. Given these results, the most appropriate position for regulators is precautionary: they should enact and enforce policies capable of effectively dampening excessive speculative trading on the commodities markets for food.
On the possible origin and evolution of the genetic code
NASA Technical Reports Server (NTRS)
Jukes, T. H.
1974-01-01
The genetic code is examined for indications of possible preceding codes that existed during early evolution. Eight of the 20 amino acids are coded by 'quartets' of codons with fourfold degeneracy, and 16 such quartets can exist, so that an earlier code could have provided for 15 or 16 amino acids, rather than 20. If twofold degeneracy is postulated for the first position of the codon, there could have been ten amino acids in the code. It is speculated that these may have been phenylalanine, valine, proline, alanine, histidine, glutamine, glutanic acid, aspartic acid, cysteine and glycine. There is a notable deficiency of arginine in proteins, despite the fact that it has six codons. Simultaneously, there is more lysine in proteins than would be expected from its two codons, if the four bases in mRNA are equiprobable and are arranged randomly. It is speculated that arginine is an 'intruder' into the genetic code, and that it may have displayed another amino acid such as ornithine, or may even have displayed lysine from some of its previous codon assignments. As a result, natural selection has favored lysine against the fact that it has only two codons.

Previous analyses of a large ensemble of stock markets have demonstrated that a log-periodic power law (LPPL) behavior of the prices constitutes a qualifying signature of speculative bubbles that often land with a crash. We detect such a LPPL signature in the foreign capital inflow during the bubble on the US markets culminating in March 2000. We detect a weak synchronization and lag with the NASDAQ LPPL pattern. We propose to rationalize these observations by the existence of positive feedback loops between market-appreciation/increased-spending/increased-deficit-of-balance-of-payment/larger-foreign-surplus/increased-foreign-capital-inflows and so on. Our analysis suggests that foreign capital inflow has been following rather than causing the bubble. We then combine a macroeconomic analysis of feedback processes occurring between the economy and the stock market with a technical analysis of more than 200 years of the DJIA to investigate possible scenarios for the future, three years after the end of the bubble and deep into a bearish regime. We conclude that the low interest rates and depreciating dollar are the indispensable ingredients for a lower sustainable burden of the global US debt structure and for allowing the slow rebuilding of an internationally competitive economy. This will probably be accompanied by a weak stock market on the medium term as the growing Federal deficit is consuming a large part of the foreign surplus dollars and the stock market is remaining a very risky and unattractive investment. Notwithstanding strong surge of liquidity in recent months orchestrated by the Federal Reserve, this macroeconomic analysis which incorporates an element of collective behavior is in line with our recent analyses of the bearish market that started in 2000 in terms of a LPPL “anti-bubble”. We project this LPPL anti-bubble to continue at least for another year. On the short term, increased availability of liquidity (M1) and self-fulfilling bullish anticipations may hold the stock market for a while.
2014 U.S. Offshore Wind Market Report: Industry Trends, Technology Advancement, and Cost Reduction

Smith, Aaron; Stehly, Tyler; Walter Musial
2015 has been an exciting year for the U.S. offshore wind market. After more than 15 years of development work, the U.S. has finally hit a crucial milestone; Deepwater Wind began construction on the 30 MW Block Island Wind Farm (BIWF) in April. A number of other promising projects, however, have run into economic, legal, and political headwinds, generating much speculation about the future of the industry. This slow, and somewhat painful, start to the industry is not without precedent; each country in northern Europe began with pilot-scale, proof-of-concept projects before eventually moving to larger commercial scale installations. Now, aftermore » more than a decade of commercial experience, the European industry is set to achieve a new deployment record, with more than 4 GW expected to be commissioned in 2015, with demonstrable progress towards industry-wide cost reduction goals. DWW is leveraging 25 years of European deployment experience; the BIWF combines state-of-the-art technologies such as the Alstom 6 MW turbine with U.S. fabrication and installation competencies. The successful deployment of the BIWF will provide a concrete showcase that will illustrate the potential of offshore wind to contribute to state, regional, and federal goals for clean, reliable power and lasting economic development. It is expected that this initial project will launch the U.S. industry into a phase of commercial development that will position offshore wind to contribute significantly to the electric systems in coastal states by 2030.« less

Conditional branches incur a severe performance penalty in wide-issue, deeply pipelined processors. Speculative execution and predicated execution are two mechanisms that have been proposed for reducing this penalty. Speculative execution can completely eliminate the penalty associated with a particular branch, but requires accurate branch prediction to be effective. Predicated execution does not require accurate branch prediction to eliminate the branch penalty, but is not applicable to all branches and can increase the latencies within the program. This paper examines the performance benefit of using both mechanisms to reduce the branch execution penalty. Predicated execution is used to handle the hard-to-protectmore » branches and speculative execution is used to handle the remaining branches. The hard-to-predict branches within the program are determined by profiling. We show that this approach can significantly reduce the branch execution penalty suffered by wide-issue processors.« less

This review presents a general theory of financial crashes and of stock market instabilities that his co-workers and the author have developed over the past seven years. We start by discussing the limitation of standard analyses for characterizing how crashes are special. The study of the frequency distribution of drawdowns, or runs of successive losses shows that large financial crashes are “outliers”: they form a class of their own as can be seen from their statistical signatures. If large financial crashes are “outliers”, they are special and thus require a special explanation, a specific model, a theory of their own. In addition, their special properties may perhaps be used for their prediction. The main mechanisms leading to positive feedbacks, i.e., self-reinforcement, such as imitative behavior and herding between investors are reviewed with many references provided to the relevant literature outside the narrow confine of Physics. Positive feedbacks provide the fuel for the development of speculative bubbles, preparing the instability for a major crash. We demonstrate several detailed mathematical models of speculative bubbles and crashes. A first model posits that the crash hazard drives the market price. The crash hazard may sky-rocket at some times due to the collective behavior of “noise traders”, those who act on little information, even if they think they “know”. A second version inverses the logic and posits that prices drive the crash hazard. Prices may skyrocket at some times again due to the speculative or imitative behavior of investors. According the rational expectation model, this entails automatically a corresponding increase of the probability for a crash. We also review two other models including the competition between imitation and contrarian behavior and between value investors and technical analysts. The most important message is the discovery of robust and universal signatures of the approach to crashes. These precursory patterns have been documented for essentially all crashes on developed as well as emergent stock markets, on currency markets, on company stocks, and so on. We review this discovery at length and demonstrate how to use this insight and the detailed predictions obtained from these models to forecast crashes. For this, we review the major crashes of the past that occurred on the major stock markets of the planet and describe the empirical evidence of the universal nature of the critical log-periodic precursory signature of crashes. The concept of an “anti-bubble” is also summarized, with the Japanese collapse from the beginning of 1991 to present, taken as a prominent example. A prediction issued and advertised in January 1999 has been until recently born out with remarkable precision, predicting correctly several changes of trends, a feat notoriously difficult using standard techniques of economic forecasting. We also summarize a very recent analysis the behavior of the U.S. S&P500 index from 1996 to August 2002 and the forecast for the two following years. We conclude by presenting our view of the organization of financial markets.

Laughter facilitates the adaptive response to stress by increasing the psychological distance from distress and by enhancing social relations. To test these hypotheses, the authors related measures of bereaved adults' laughter and smiling 6 months postloss to measures of their (a) subjective emotion and dissociation from distress, (b) social relations, and (c) responses they evoked in others. Duchenne laughter, which involves orbicularis oculi muscle action, related to self-reports of reduced anger and increased enjoyment, the dissociation of distress, better social relations, and positive responses from strangers, whereas non-Duchenne laughter did not. Lending credence to speculations in the ethological literature, Duchenne laughter correlated with different intrapersonal and interpersonal responses than Duchenne smiles. Discussion focuses on the relevance of these findings to theories of positive emotion.

Although frequent fluctuations in domestic hog prices seriously affect the stability and robustness of the hog supply chain, hog futures (an effective hedging instrument) have not been listed in China. To better understand hog futures market hedging, it is important to study the steady state of intersubjective bidding. This paper uses evolutionary game theory to construct a game model between hedgers and speculators in the hog futures market, and replicator dynamic equations are then used to obtain the steady state between the two trading entities. The results show that the steady state is one in which hedgers adopt a "buy" strategy and speculators adopt a "do not speculate" strategy, but this type of extreme steady state is not easily realized. Thus, to explore the rational proportion of hedgers and speculators in the evolutionary stabilization strategy, bidding processes were simulated using weekly average hog prices from 2006 to 2015, such that the conditions under which hedgers and speculators achieve a steady state could be analyzed. This task was performed to achieve the stability critical point, and we show that only when the value of λ is satisfied and the conditions of hog futures price changes and futures price are satisfied can hedgers and speculators achieve a rational proportion and a stable hog futures market. This market can thus provide a valuable reference for the development of the Chinese hog futures market and the formulation and guidance of relevant departmental policies.

Gaucher disease is the most frequent lysosomal lipid storage disease. It results from deficient glucocerebrosidase activity and is transmitted as an autosomal recessive trait. Three clinical forms of Gaucher disease have been described: type 1, non-neuronopathic; type 2, acute neuronopathic; and type 3, subacute neuronopathic. We have sequenced the full length cDNA of the glucocerebrosidase gene and identified an uncommon mutation in nucleotide position 1604 (genoma DNA nucleotide position 6683) from a Gaucher disease patient of Jewish-Polish-Russian descent with type 1 Gaucher disease. It is a G{yields}A transition in exon 11 that results in {sup 496}Arg{yields}{sup 496}His of glucocerebrosidase. Thismore » missense mutation is present in the heterozygous form and creates a new cleavage site for the endonuclease HphI. We have developed a simple method to detect the presence of this mutation by using HphI restriction fragment length polymorphism analysis of glucocerebrosidase genomic DNA or cDNA. The mutation in the other Gaucher allele of this patient is an A{yields}G transition at cDNA nucleotide position 1226 which creates an XhoI cleavage site after PCR mismatch amplification. The presence of this mutation was also confirmed by sequence analysis. Based on previous reports that mutation 1226 is present only in type 1 Gaucher disease and the observation that there is no neurological involvement in this patient, we conclude that our patient with the 1226/1604 genotype is diagnosed as having type 1 Gaucher disease. Since it was also postulated that mutation 1226 in the homozygous form will usually result in a good prognosis, we speculate that the orthopedic complications and the unusual presence of glomerulosclerosis in this patient may be attributable to the mutation at nucleotide 1604. This speculation will require a description of more patients with this mutation for confirmation. 32 refs., 5 figs.« less
Atmospheric profiles from active space-based radio measurements

The paper describes determinations of atmospheric profiles from space-based radio measurements and the retrieval methodology used, with special attention given to the measurement procedure and the characteristics of the soundings. It is speculated that reliable profiles of the terrestrial atmosphere can be obtained by the occultation technique from the surface to a height of about 60 km. With the full complement of 21 the Global Positioning System (GPS) satellites and one GPS receiver in sun synchronous polar orbit, a maximum of 42 soundings could be obtained for each complete orbit or about 670 per day, providing almost uniform global coverage.

Learned helplessness behavior and cognitions were assessed in 95 kindergarten-age children during a series of impossible puzzle trials followed by a solvable puzzle trial. Latent growth curve analysis revealed reliable individual differences in the trajectories of children's affect, motivation, and self-cognitions over time. Parents' reports of negative life events, harsh/negative parenting, and warm/positive parenting were associated with their children's learned helplessness behavioral trajectories and outcomes over the course of the puzzle trials. Results support speculations about the developmental origins of depressive explanatory or attributional style in children.
Granular cell tumor in an endangered Puerto Rican Amazon parrot (Amazon vittata)
Quist, C.F.; Latimer, K.S.; Goldade, S.L.; Rivera, A.; Dein, F.J.
1999-01-01
A 3 cm diameter mass from the metacarpus of a Puerto Rican Amazon parrot was diagnosed as a granular cell tumour based on light microscopy. The cytoplasmic granules were periodic-acid Schiff positive and diastase resistant. Ultrastructural characteristics of the cells included convoluted nuclei and the presence of numerous cytoplasmic tertiary lysosomes. This is only the second granular cell tumour reported in a bird. We speculate that most granular cell tumours are derived from cells that are engaged in some type of cellular degradative process, creating a similar morphologic appearance, but lacking a uniform histogenesis.

The influence of rearing order on personality development within two adoption cohorts.
Beer, J M; Horn, J M
2000-08-01
There is an extensive literature on the relationship between birth order and psychological traits, but no previous study has investigated the influence of ordinal position on personality development within adoptive siblings. Such a design is important because it effectively separates the effects of biological birth order and rearing order. Here we report data from two adoption cohorts in which subjects were biological first-borns reared in various ordinal positions. Data were analyzed with reference to Sulloway's (1996) evolutionarily based sibling rivalry theory of birth order effects. Between- and within-family analyses indicated that rearing order's influence on personality was very weak. The only clear difference was for conscientiousness, on which first-reared siblings scored higher. We draw possible implications for Sulloway's theory and speculate upon an alternative, prenatal biological process that may produce birth order differences.
On extremal surfaces and de Sitter entropy
NASA Astrophysics Data System (ADS)
Narayan, K.
2018-04-01
We study extremal surfaces in the static patch coordinatization of de Sitter space, focusing on the future and past universes. We find connected timelike codim-2 surfaces on a boundary Euclidean time slice stretching from the future boundary I+ to the past boundary I-. In a limit, these surfaces pass through the bifurcation region and have minimal area with a divergent piece alone, whose coefficient is de Sitter entropy in 4-dimensions. These are reminiscent of rotated versions of certain surfaces in the AdS black hole. We close with some speculations on a possible dS / CFT interpretation of 4-dim de Sitter space as dual to two copies of ghost-CFTs in an entangled state. For a simple toy model of two copies of ghost-spin chains, we argue that similar entangled states always have positive norm and positive entanglement.

Crisis, leadership, consensus: the past and future federal role in health.
Boufford, J I
1999-06-01
This paper touches on patterns of federal government involvement in the health sector since the late 18th century to the present and speculates on its role in the early decades of the 21st century. Throughout the history of the US, government involvement in the health sector came only in the face of crisis, only when there was widespread consensus, and only through sustained leadership. One of the first health-related acts of Congress came about as a matter of interstate commerce regarding the dilemma as to what to do about treating merchant seamen who had no affiliation with any state. Further federal actions were implemented to address epidemics, such as from yellow fever, that traveled from state to state through commercial ships. Each federal action was met with concern and resistance from states' rights advocates, who asserted that the health of the public was best left to the states and localities. It was not until the early part of the 20th century that a concern for social well-being, not merely commerce, drove the agenda for public health action. Two separate campaigns for national health insurance, as well as a rapid expansion of programs to serve the specific health needs of specific populations, led finally to the introduction of Medicaid and Medicare in the 1960s, the most dramatic example of government intervention in shaping the personal health care delivery system in the latter half of the 20th century. As health costs continued to rise and more and more Americans lacked adequate health insurance, a perceived crisis led President Clinton to launch his 1993 campaign to insure every American--the third attempt in this century to provide universal coverage. While the crisis was perceived by many, there was no consensus on action, and leadership outside government was missing. Today, the health care crisis still looms. Despite an economic boom, 1 million Americans lose their health insurance each year, with 41 million Americans, or 15% of the population, lacking coverage. Private premiums are going up again as federal programs are capped and the lack of a federal framework for quality assurance leads to growing problems of access and quality that will need to be addressed as we enter the 21st century. What role will government play?
Visionary medicine: speculative fiction, racial justice and Octavia Butler's 'Bloodchild'.
Pasco, John Carlo; Anderson, Camille; DasGupta, Sayantani
2016-12-01
Medical students across the USA have increasingly made the medical institution a place for speculating racially just futures. From die-ins in Fall 2014 to silent protests in response to racially motivated police brutality, medical schools have responded to the public health crisis that is racial injustice in the USA. Reading science fiction may benefit healthcare practitioners who are already invested in imagining a more just, healthier futurity. Fiction that rewrites the future in ways that undermine contemporary power regimes has been termed 'visionary fiction'. In this paper, the authors introduce 'visionary medicine' as a tool for teaching medical students to imagine and produce futures that preserve health and racial justice for all. This essay establishes the connections between racial justice, medicine and speculative fiction by examining medicine's racially unjust past practices, and the intersections of racial justice and traditional science and speculative fiction. It then examines speculative fiction author Octavia Butler's short story 'Bloodchild' as a text that can introduce students of the medical humanities to a liberatory imagining of health and embodiment, one that does not reify and reinscribe boundaries of difference, but reimagines the nature of Self and Other, power and collaboration, agency and justice.

Utilizing ERTS-A imagery for tectonic analysis through study of Big Horn Mountains region

Hoppin, R. A. (Principal Investigator)
1973-01-01
The author has identified the following significant results. MSS scene 1085-17294 of the Big Horn region has been subjected to detailed structural analysis. Band 7 is particularly good for revealing structural and drainage patterns because of enhance topographic detail and the subdued vegetational contrasts. Considerable stereo coverage through sidelap with adjoining scenes adds to the effectiveness of the study and has been used on both positive transparencies and enlarged prints. Negative prints of Band 7 positive transparencies have proven to be much more useful than positive prints because the higher resolution of the positive transparencies can be maintained. The Bighorn Mountains are crisscrossed by a number of prominent topographic linears, most of which can be correlated with known fault and shear zones in the Precambrian crystalline core. Many of these do not appear to continue into the flanking sedimentary rocks and a few that do (Tensleep, Tongue River lineaments) are very difficult to trace farther out into the basins. The Tongue River lineament, long a source of speculation and uncertainty as to its existence, appears as a very prominent discontinuity in the imagery.
December the Twentieth (2012) Is Too Late: Addressing the "Science” of Doomsday

Manning, Jim; Fraknoi, A.; Schultz, G.
2010-01-01
The claimed end date of the Mayan "Long Count” calendar cycle on December 21, 2012 has given rise to assorted "New Age” speculations about major transformative events occurring in conjunction with the completion of this cycle. These speculations range from a global consciousness shift to some higher plane of understanding, to various apocalyptic disasters including increased solar activity, geomagnetic reversal, crustal displacement, and collision with a rogue planet. In recent years, the notion has spawned numerous books, History Channel programs, and a Sony Pictures film to air in late 2009 (accompanied by a viral marketing campaign describing various doomsday scenarios and offering a "survival lottery"). This current "meme” (that is, an idea that replicates through cultural transmission) represents a potential teachable moment for scientists and EPO professionals alike, but we shouldn't wait until the purported Eve of Destruction (or of Transcendental Bliss) to comment. The presenter will describe what the Astronomical Society of the Pacific is planning to do to address the attendant issues, to separate science from pseudoscience, to encourage critical thinking in the consideration of such claims, and to remind the public of legitimate threats to the planet about which we can make a positive difference. He will further encourage others to do the same.

Two meta-analyses evaluated shifts across the ovulatory cycle in women's mate preferences but reported very different findings. In this journal, we reported robust evidence for the pattern of cycle shifts predicted by the ovulatory shift hypothesis (Gildersleeve, Haselton, & Fales, 2014). However, Wood, Kressel, Joshi, and Louie (2014) claimed an absence of compelling support for this hypothesis and asserted that the few significant cycle shifts they observed were false positives resulting from publication bias, p-hacking, or other research artifacts. How could 2 meta-analyses of the same literature reach such different conclusions? We reanalyzed the data compiled by Wood et al. These analyses revealed problems in Wood et al.'s meta-analysis-some of which are reproduced in Wood and Carden's (2014) comment in the current issue of this journal-that led them to overlook clear evidence for the ovulatory shift hypothesis in their own set of effects. In addition, we present right-skewed p-curves that directly contradict speculations by Wood et al.; Wood and Carden; and Harris, Pashler, and Mickes (2014) that supportive findings in the cycle shift literature are false positives. Therefore, evidence from both of the meta-analyses and the p-curves strongly supports genuine, robust effects consistent with the ovulatory shift hypothesis and contradicts claims that these effects merely reflect publication bias, p-hacking, or other research artifacts. Unfounded speculations about p-hacking distort the research record and risk unfairly damaging researchers' reputations; they should therefore be made only on the basis of firm evidence.

Preoperative lung cancer with mediastinal lymph nodes metastasis can be diagnosed by vedio mediastinoscopy (VM) and CT. This study was to explore the value of VM and CT in the diagnosis of N staging of preoperative lung cancer, and to discuss the difference between the two methods. Forty-eight cases diagnosed of lung cancer by CT or PET-CT were examined by VM. The sensitivity, specificity, validity, positive predictive value and negative predictive value of VM and CT were speculated according to the postoperative pathological reports, and the difference between VM and CT in the diagnosis of lung cancer with mediastinal lymph nodes metastasis was discussed. (1)Under the examination of VM, 31 patients with the negative outcome received the direct operation; 14 patients with N2 received 2 courses of neoadjuvant chemotherapy before operation; 3 patients with N3 received chemotherapy and/or radiotherapy. (2)Forty-one cases with final diagnosis of lung cancer were used as samples to speculate the sensitivity, specificity, validity, positive predictive value and negative predictive value of VM. They were 93.3%, 100%, 97.6%, 100%, 96.3%, which of CT were 66.7%, 53.8%, 58.5%, 45.5%, 73.7% (Chi-square=4.083, P=0.039), the difference between VM and CT was statistically significant. (3)In this group, the complications of VM incidence rate was 2.08% (1/48), and the case was pneumothorax. VM is superior to CT in the diagnosis of N staging of preoperative lung cancer; Due to its safety and effectiveness, VM will be wildly used in the field of thoracic surgery.

In order to respond to the general paucity of information on the chronology of ubiquitous small rock falls and slides that litter the slopes of desert mountain ranges, a case study in the Sonoran Desert reveals new insight into the desert geomorphology of mountain slopes. Rock falls and rock slides in the McDowell Mountains that abut metropolitan Phoenix, USA, fall in three chronometric groupings dated by conventional radiocarbon and rock varnish microlamination methods. First, the oldest events are > 74 ka and take the form of stable colluvial boulder fields - positive relief features that are tens of meters long and a few meters wide. Second, randomly sampled slides and falls of various sizes and positions wasted during wetter periods of the terminal Pleistocene and Holocene. Third, an anomalous clustering of slides and falls occurred during the late Medieval Warm Period (Medieval Climatic Anomaly) when an extreme storm was a possible but unlikely trigger. One speculative hypothesis for the cluster of Medieval Warm Period events is that a small to moderate sized earthquake shook heavily shattered bedrock - close to failure - just enough to cause a spate of rock falls and slides. A second speculative hypothesis is that this dry period enhanced physical weathering processes such as dirt cracking. However, the reasons for the recent clustering of rock falls remain enigmatic. While the temporal distribution of slides and falls suggests a minimal hazard potential for homes and roads on the margins of the McDowell Mountains, this finding may not necessary match other desert ranges in metropolitan Phoenix or mountains with different rock types and structures that abut other arid urban centers.

Association between asthma and female sex hormones.
Baldaçara, Raquel Prudente de Carvalho; Silva, Ivaldo
2017-01-01
The relationship between sex hormones and asthma has been evaluated in several studies. The aim of this review article was to investigate the association between asthma and female sex hormones, under different conditions (premenstrual asthma, use of oral contraceptives, menopause, hormone replacement therapy and pregnancy). Narrative review of the medical literature, Universidade Federal do Tocantins (UFT) and Universidade Federal de São Paulo (Unifesp). We searched the CAPES journal portal, a Brazilian platform that provides access to articles in the MEDLINE, PubMed, SciELO, and LILACS databases. The following keywords were used based on Medical Subject Headings: asthma, sex hormones, women and use of oral contraceptives. The associations between sex hormones and asthma remain obscure. In adults, asthma is more common in women than in men. In addition, mortality due to asthma is significantly higher among females. The immune system is influenced by sex hormones: either because progesterone stimulates progesterone-induced blocking factor and Th2 cytokines or because contraceptives derived from progesterone and estrogen stimulate the transcription factor GATA-3. The associations between asthma and female sex hormones remain obscure. We speculate that estrogen fluctuations are responsible for asthma exacerbations that occur in women. Because of the anti-inflammatory action of estrogen, it decreases TNF-α production, interferon-γ expression and NK cell activity. We suggest that further studies that highlight the underlying physiopathological mechanisms contributing towards these interactions should be conducted.

Increased infection susceptibility in the diabetic population is a controversial issue in the clinical field. The greater frequency of infections in diabetic patients has been speculated as caused by the hyperglycemic environment that favors immune dysfunction. The aim of this study was to investigate the proportion of positive bacterial cultures in a series of diabetic individuals who underwent forensic investigations and assess the frequency of hyperglycemia at the time of death in these cases as well as the percentage of diabetics with cause of death due to bacterial infection. Forensic autopsy cases characterized by positive bacterial cultures and pre-existing diagnosis of diabetes mellitus were included in the study. Initial findings revealed that 12% (7/58 cases) of positive bacterial cultures concerned individuals with a pre-existing diagnosis of diabetes mellitus. Bacterial infection was considered to be the cause of death in 22% (7/31 cases) of diabetics with positive bacterial cultures. Hyperglycemia could be identified in 1 case only at the time of death. These preliminary results highlight the usefulness of systematically performing postmortem bacteriology in the forensic setting to more precisely characterize infectious risk factors in diabetics.

3,4-Methylenedioxymethamphetamine (MDMA, 'ecstasy') is used recreationally to improve mood and sociability, and has generated clinical interest as a possible adjunct to psychotherapy. One way that MDMA may produce positive 'prosocial' effects is by changing responses to emotional stimuli, especially stimuli with social content. Here, we examined for the first time how MDMA affects subjective responses to positive, negative and neutral emotional pictures with and without social content. We hypothesized that MDMA would dose-dependently increase reactivity to positive emotional stimuli and dampen reactivity to negative stimuli, and that these effects would be most pronounced for pictures with people in them. The data were obtained from two studies using similar designs with healthy occasional MDMA users (total N = 101). During each session, participants received MDMA (0, 0.75 and 1.5 mg/kg oral), and then rated their positive and negative responses to standardized positive, negative and neutral pictures with and without social content. MDMA increased positive ratings of positive social pictures, but reduced positive ratings of non-social positive pictures. We speculate this 'socially selective' effect contributes to the prosocial effects of MDMA by increasing the comparative value of social contact and closeness with others. This effect may also contribute to its attractiveness to recreational users. © The Author (2014). Published by Oxford University Press. For Permissions, please email: journals.permissions@oup.com.

There is wide agreement that one of the most significant impediments to the performance of current and future pipelined superscalar processors is the presence of conditional branches in the instruction stream. Speculative execution is one solution to the branch problem, but speculative work is discarded if a branch is mispredicted. For it to be effective, speculative work is discarded if a branch is mispredicted. For it to be effective, speculative execution requires a very accurate branch predictor; 95% accuracy is not good enough. This paper proposes branch classification, a methodology for building more accurate branch predictors. Branch classification allows anmore » individual branch instruction to be associated with the branch predictor best suited to predict its direction. Using this approach, a hybrid branch predictor can be constructed such that each component branch predictor predicts those branches for which it is best suited. To demonstrate the usefulness of branch classification, an example classification scheme is given and a new hybrid predictor is built based on this scheme which achieves a higher prediction accuracy than any branch predictor previously reported in the literature.« less

During herpes simplex virus-1 (HSV-1) latency in sensory neurons, LAT (latency-associated transcript) is the only abundantly expressed viral gene. LAT plays an important role in the HSV-1 latency-reactivation cycle, because LAT deletion mutants have a significantly decreased reactivation phenotype. Based solely on sequence analysis, it was speculated that LAT encodes a ribozyme that plays an important role in how LAT enhances the virus’ reactivation phenotype. Because LAT ribozyme activity has never been reported, we decided to test the converse hypothesis, namely, that this region of LAT does not encode a ribozyme function important for LAT’s ability to enhance the reactivation phenotype. We constructed a viral mutant (LAT-Rz) in which the speculated ribozyme consensus sequence was altered such that no ribozyme was encoded. We report here that LAT-Rz had a wild-type reactivation phenotype in mice, confirming the hypothesis that the speculated LAT ribozyme is not a dominant factor in stimulating the latency-reactivation cycle in mice.

The Limits of Exercise Physiology: From Performance to Health.
Gabriel, Brendan M; Zierath, Juleen R
2017-05-02
Many of the established positive health benefits of exercise have been documented by historical discoveries in the field of exercise physiology. These investigations often assess limits: the limits of performance, or the limits of exercise-induced health benefits. Indeed, several key findings have been informed by studying highly trained athletes, in addition to healthy or unhealthy people. Recent progress has been made in regard to skeletal muscle metabolism and personalized exercise regimes. In this perspective, we review some of the historical milestones of exercise physiology, discuss how these inform contemporary knowledge, and speculate on future questions.

A new methodology to estimate the dynamics of femtosecond laser-induced impulsive force generated into water under microscope was developed. In this method, the position shift of the bead in water before and after the femtosecond laser irradiation was investigated experimentally and compared with motion equation assuming stress wave propagation with expansion and collapse the cavitation bubble. In the process of the comparison, parameters of force and time of the stress wave were determined. From these results, dynamics of propagations of shock and stress waves, cavitation bubble generation, and these actions to micro-objects were speculated.
Demonstration of elastic fibres with reagents for detection of magnesium.
Müller, W; Firsching, R
1991-01-01
Investigation of elastic fibres in various human and animal tissues with the reagents quinalizarin, magneson II, and titan yellow for the detection of magnesium revealed striking positive results. After pretreatment of skin and ligamentum flavum with elastase the tests were negative. The results support the supposition that the amount of magnesium in elastic fibres is sufficient for histochemical detection. It is speculated that the marked chelate-forming property of magnesium, or its antagonistic function to calcium, is associated with the elastic property of the fibres.

Despite much speculation, little is known about the net effects of the economy on the employed workforce. To fill this gap, we used state-level data collected by the Bureau of Labor Statistics to examine the effects of the condition of the economy, as indicated by the unemployment rate, on incidence rates of absence reportedly due to symptoms of illness and violent acts in the workplace for 43 states from 1992 to 2009. Our results suggest that the unemployment rate is positively associated with these indicators of absenteeism, and that these effects are delayed in time.

Recent increases in basic food prices are severely affecting vulnerable populations worldwide. Proposed causes such as shortages of grain due to adverse weather, increasing meat consumption in China and India, conversion of corn to ethanol in the United States, and investor speculation on commodity markets lead to widely differing implications for policy. A lack of clarity about which factors are responsible reinforces policy inaction. Here, for the first time to our knowledge, we construct a dynamic model that quantitatively agrees with food prices. The results show that the dominant causes of price increases are investor speculation and ethanol conversion. Models that just treat supply and demand are not consistent with the actual price dynamics. The two sharp peaks in 2007/2008 and 2010/2011 are specifically due to investor speculation, whereas an underlying upward trend is due to increasing demand from ethanol conversion. The model includes investor trend following as well as shifting between commodities, equities, and bonds to take advantage of increased expected returns. Claims that speculators cannot influence grain prices are shown to be invalid by direct analysis of price-setting practices of granaries. Both causes of price increase, speculative investment and ethanol conversion, are promoted by recent regulatory changes—deregulation of the commodity markets, and policies promoting the conversion of corn to ethanol. Rapid action is needed to reduce the impacts of the price increases on global hunger. PMID:26504216

There is an unresolved debate about the potential effects of financial speculation on food prices and price volatility. Germany's largest financial institution and leading global investment bank recently decided to continue investing in agricultural commodities, stating that there is little empirical evidence to support the notion that the growth of agricultural-based financial products has caused price increases or volatility. The statement is supported by a recently published literature review, which concludes that financial speculation does not have an adverse effect on the functioning of the agricultural commodities market. As public health professionals concerned with global food insecurity, we have appraised the methodological quality of the review using a validated and reliable appraisal tool. The appraisal revealed major shortcomings in the methodological quality of the review. These were particularly related to intransparencies in the search strategy and in the selection/presentation of studies and findings; the neglect of the possibility of publication bias; a lack of objective or rigorous criteria for assessing the scientific quality of included studies and for the formulation of conclusions. Based on the results of our appraisal, we conclude that it is not justified to reject the hypothesis that financial speculation might have adverse effects on food prices/price volatility. We hope to initiate reflections about scientific standards beyond the boundaries of disciplines and call for high quality, rigorous systematic reviews on the effects of financial speculation on food prices or price volatility.

General Halleck's itchy elbows.
Cropley, Thomas G
2007-01-01
General Henry Wager Halleck served as general-in-chief and chief of staff of the Federal army from 1862-1865. Unpopular with troops as well as with many members of the Lincoln administration, he was a particular source of irritation to Secretary of Navy Gideon Welles. In his posthumously-published diary of the war years, Welles viciously criticized Halleck for his failings as army commander. Welles also derided Halleck's personality and personal appearance. Welles found the general's habitual elbow-scratching annoying enough to mention it in five separate diary entries. This depiction of Halleck ceaselessly, nervously scratching his elbows has entered Civil War folklore. Why did Halleck scratch his elbows? Two possibilities exist. Either he did so compulsively, as a nervous habit, or he was scratching an itch. In this paper, I present a speculative argument that Halleck may have had a skin disease, possibly atopic dermatitis, and that this may have contributed to or have been the sole cause of his elbow scratching.
Viewing condition dependence of the gaze-evoked nystagmus in Arnold Chiari type 1 malformation.
Ghasia, Fatema F; Gulati, Deepak; Westbrook, Edward L; Shaikh, Aasef G
2014-04-15
Saccadic eye movements rapidly shift gaze to the target of interest. Once the eyes reach a given target, the brainstem ocular motor integrator utilizes feedback from various sources to assure steady gaze. One of such sources is cerebellum whose lesion can impair neural integration leading to gaze-evoked nystagmus. The gaze evoked nystagmus is characterized by drifts moving the eyes away from the target and a null position where the drifts are absent. The extent of impairment in the neural integration for two opposite eccentricities might determine the location of the null position. Eye in the orbit position might also determine the location of the null. We report this phenomenon in a patient with Arnold Chiari type 1 malformation who had intermittent esotropia and horizontal gaze-evoked nystagmus with a shift in the null position. During binocular viewing, the null was shifted to the right. During monocular viewing, when the eye under cover drifted nasally (secondary to the esotropia), the null of the gaze-evoked nystagmus reorganized toward the center. We speculate that the output of the neural integrator is altered from the bilateral conflicting eye in the orbit position secondary to the strabismus. This could possibly explain the reorganization of the location of the null position. Copyright © 2014 Elsevier B.V. All rights reserved.

We report observation of hexatic order in Abrikosov flux lattices in very clean crystals of the high- Tc superconductor Bi 2.1Sr 1.9Ca 0.9Cu 2O 8+δ (BSCCO). Our experiments consist of in situ magnetic decoration of the flux lattice at 4.2 K. Analysis of the decoration images shows that the positional order decays exponentially with a correlation length of a few lattice constants while the orientational order persists for hundreds of lattice constants and decays algebraically with an exponent η 6 = 0.6 ± 0.01. Our results confirm recent theoretical speculation that the positional order should be far more sensitive to disorder than the orientational order and that the low-temperature ordered phase of the flux lines in these systems might be an hexatic glass.

Cloacogenic Adenocarcinoma of the Vulva: A Case Report and Review of the Literature.
Tepeoğlu, Merih; Üner, Halit; Haberal, A Nihan; Özen, Özlem; Kuşçu, Esra
2017-02-04
Primary adenocarcinoma of the vulva, unrelated to the native glands of perineum is an extremely rare neoplasm. Despite awareness of this lesion for over 40 years, the origin is not beyond speculation. The most reasonable hypothesis is based on the remnants of cloacal differentiation during early days of life. Here we report the case of a 60-year-old patient with a vulvar mass, who underwent partial vulvectomy and bilateral regional lymph node dissection. The tumor was composed of papillary and complex glandular structures and exhibited diffuse positivity for cytokeratin 20 and polyclonal CEA, CDX2, and focal positivity with cytokeratin 7. Unlike the indolent behavior of this malignant neoplasm according to the literature, we found two metastatic inguinal lymph nodes. She did not receive adjuvant therapy and is still alive, free of disease 38 months after surgery. We present different aspects of vulvar adenocarcinomas with a case report.
Conformational transition of membrane-associated terminally-acylated HIV-1 Nef

Many proteins are post-translationally modified by acylation targetting them to lipid membranes. While methods such as X-ray crystallography and NMR are available to determine the structure of folded proteins in solution, the precise position of folded domains relative to a membrane remains largely unknown. We used neutron and X-ray reflection methods to measure the displacement of the core domain of HIV Nef from lipid membranes upon insertion of the N-terminal myristate group. Nef is one of several HIV-1 accessory proteins and an essential factor in AIDS progression. Upon insertion of the myristate and residues from the N-terminal arm, Nef transitions from a closed to open conformation that positions the core domain 70 Å from the lipid headgroups. This work rules out speculation that the Nef core remains closely associated with the membrane to optimize interactions with the cytoplasmic domain of MHC-1. PMID:24035710

The development of an electron-theory of metals is closely connected with early speculation in the period before Maxwell (W Weber and others) regarding electrical conductivity in metals. These Speculations were in contrast with Faraday's view of an all-embracing molecular dielectric polarisation, and a subsequent passage of charges in metallic conductors. In terms of the empirical law of Wiedemann-Franz-Lorenz, the conductivity of electricity and heat had to be treated commonly. The classical electron-theory of metals (Riecke, Drude, H.A. Lorentz) reached a dead end on account of problems concerned with specific heat capacity. Sommerfeld, by means of the Quantum theory and the Fermi-Statistic, could find the solution.

With its contribution to trade, its coupling with national security, and its symbolism of U.S. technological strength, the U.S. aerospace industry holds a unique position in the Nation's industrial structure. Federal science and technology policy and Federal scientific and technical information (STI) policy loom important as strategic contributions to the U.S. aerospace industry's leading competitive position. However, three fundamental policy problems exist. First, the United States lacks a coherent STI policy and a unified approach to the development of such a policy. Second, policymakers fail to understand the relationship of STI to science and technology policy. Third, STI is treated as a part of general information policy, without any recognition of its uniqueness. This paper provides an overview of the Federal information policy structure as it relates to STI and frames the policy issues that require resolution.

During visits to 34 federally inspected establishments producing frozen meat and gravy, 541 production line samples and 535 finished product units were collected for bacteriological analyses. It was found that more than 70% of the sets of finished product (10 units/set) produced under good manufacturing practices had: (i) four or fewer coliform-positive units, (ii) two or fewer Escherichia coli-positive units, (iii) three or fewer Staphylococcus aureus-positive units, and (iv) an aerobic plate count of fewer than 50,000/g (geometric mean of 10 units). All finished product units were negative for salmonellae.

Although frequent fluctuations in domestic hog prices seriously affect the stability and robustness of the hog supply chain, hog futures (an effective hedging instrument) have not been listed in China. To better understand hog futures market hedging, it is important to study the steady state of intersubjective bidding. This paper uses evolutionary game theory to construct a game model between hedgers and speculators in the hog futures market, and replicator dynamic equations are then used to obtain the steady state between the two trading entities. The results show that the steady state is one in which hedgers adopt a “buy” strategy and speculators adopt a “do not speculate” strategy, but this type of extreme steady state is not easily realized. Thus, to explore the rational proportion of hedgers and speculators in the evolutionary stabilization strategy, bidding processes were simulated using weekly average hog prices from 2006 to 2015, such that the conditions under which hedgers and speculators achieve a steady state could be analyzed. This task was performed to achieve the stability critical point, and we show that only when the value of λ is satisfied and the conditions of hog futures price changes and futures price are satisfied can hedgers and speculators achieve a rational proportion and a stable hog futures market. This market can thus provide a valuable reference for the development of the Chinese hog futures market and the formulation and guidance of relevant departmental policies. PMID:28241024

Speculative behavior and asset price dynamics.
Westerhoff, Frank
2003-07-01
This paper deals with speculative trading. Guided by empirical observations, a nonlinear deterministic asset pricing model is developed in which traders repeatedly choose between technical and fundamental analysis to determine their orders. The interaction between the trading rules produces complex dynamics. The model endogenously replicates the stylized facts of excess volatility, high trading volumes, shifts in the level of asset prices, and volatility clustering.

Speculative Considerations about Some Cardiology Enigmas.
Evora, Paulo Roberto Barbosa; Schmidt, Andre; Arcêncio, Livia; Marin-Neto, José Antonio
2017-01-01
Enigmas often lead to hypotheses and speculations. For this reason, especially for the sake of the reader's motivation, we opted for the plain discussion of some cardiology enigmas. The present text was aimed to discuss speculatively some cardiology enigmas. Text was freely designed in the context of coronary artery and heart valve diseases. The results were presented as the combination enigma/hypothesis. 1) The absence of arteriosclerosis in intramyocardial coronary arteries/ endothelium-myocardial interaction (crosstalk); 2) The unique and always confirmed superior evolution of the internal thoracic artery as coronary graft/ higher NO basal release 3) The prophylactic left internal thoracic artery graft in mildlystenosed coronary lesions/need of more accurate functional imaging techniques; 4) The high incidence of perioperative atrial fibrillation in patients with coronary artery disease/atrial ischemia associated to left circumflex coronary lesions; 5) The handling of disease-free saphenous vein grafts at the time of reoperation/biological serendipity with graft vein segments; 6) The possible aortic stenosis protection against coronary artery disease/ endothelium-myocardium interaction (crosstalk) improving NO release. The discussed topics associated with their respective speculative hypothesis remain as enigmas, but would become motivations for investigations.

Visual scan paths exhibit complex, stochastic dynamics. Even during visual fixation, the eye is in constant motion. Fixational drift and tremor are thought to reflect fluctuations in the persistent neural activity of neural integrators in the oculomotor brainstem, which integrate sequences of transient saccadic velocity signals into a short term memory of eye position. Despite intensive research and much progress, the precise mechanisms by which oculomotor posture is maintained remain elusive. Drift exhibits a stochastic statistical profile which has been modeled using random walk formalisms. Tremor is widely dismissed as noise. Here we focus on the dynamical profile of fixational tremor, and argue that tremor may be a signal which usefully reflects the workings of oculomotor postural control. We identify signatures reminiscent of a certain flavor of transient neurodynamics; toric traveling waves which rotate around a central phase singularity. Spiral waves play an organizational role in dynamical systems at many scales throughout nature, though their potential functional role in brain activity remains a matter of educated speculation. Spiral waves have a repertoire of functionally interesting dynamical properties, including persistence, which suggest that they could in theory contribute to persistent neural activity in the oculomotor postural control system. Whilst speculative, the singularity hypothesis of oculomotor postural control implies testable predictions, and could provide the beginnings of an integrated dynamical framework for eye movements across scales.

Does the market maker stabilize the market?

Zhu, Mei; Chiarella, Carl; He, Xue-Zhong; Wang, Duo
2009-08-01
The market maker plays an important role in price formation, but his/her behavior and stabilizing impact on the market are relatively unclear, in particular in speculative markets. This paper develops a financial market model that examines the impact on market stability of the market maker, who acts as both a liquidity provider and an active investor in a market consisting of two types of boundedly rational speculative investors-the fundamentalists and trend followers. We show that the market maker does not necessarily stabilize the market when he/she actively manages the inventory to maximize profits, and that rather the market maker’s impact depends on the behavior of the speculators. Numerical simulations show that the model is able to generate outcomes for asset returns and market inventories that are consistent with empirical findings.

In this paper we consider functional differential equations subjected to either instantaneous state-dependent noise, or to a white noise perturbation. The drift of the equations depend linearly on the current value and on the maximum of the solution. The functional term always provides positive feedback, while the instantaneous term can be mean-reverting or can exhibit positive feedback. We show in the white noise case that if the instantaneous term is mean reverting and dominates the history term, then solutions are recurrent, and upper bounds on the a.s. growth rate of the partial maxima of the solution can be found. When the instantaneous term is weaker, or is of positive feedback type, we determine necessary and sufficient conditions on the diffusion coefficient which ensure the exact exponential growth of solutions. An application of these results to an inefficient financial market populated by reference traders and speculators is given, in which the difference between the current instantaneous returns and maximum of the returns over the last few time units is used to determine trading strategies.

The minority game is a generic model of competing adaptive agents, which is often believed to be a model of financial markets. We discuss to which extent this is a reasonable statement, and present minimal modifications that make this model reproduce stylized facts. The resulting model shows that without speculators, prices follow random walks, and that stylized facts disappear if enough speculators take into account their market impact.
Cache directory look-up re-use as conflict check mechanism for speculative memory requests
Ohmacht, Martin
2013-09-10
In a cache memory, energy and other efficiencies can be realized by saving a result of a cache directory lookup for sequential accesses to a same memory address. Where the cache is a point of coherence for speculative execution in a multiprocessor system, with directory lookups serving as the point of conflict detection, such saving becomes particularly advantageous.

Peroxiredoxins and sports: new insights on the antioxidative defense.
Brinkmann, Christian; Brixius, Klara
2013-01-01
Peroxiredoxins (PRDXs) are multifunctional proteins that have recently received much attention. They are part of the endogenous antioxidative capacity and function as efficient scavengers, especially for hydrogen peroxides. Studies show that physical training can induce an upregulation of PRDX isoform contents in the long term. This might help counteract chronic diseases that are causally linked to a high amount of free radicals, e.g., diabetes mellitus. Furthermore, it has been demonstrated that PRDX can overoxidize under pathological conditions during acute exercise. Overoxidized PRDXs could be useful because they act as protective chaperones. Taken together, it can be speculated that physical activity has a positive effect on the PRDX system and thereby prevents cells from free radical-induced damage.

Criteria used to judge obese persons in the workplace.
Popovich, P M; Everton, W J; Campbell, K L; Godinho, R M; Kramer, K M; Mangan, M R
1997-12-01
Researchers have speculated that employers are less likely to hire obese persons for more publicly visible jobs, although this hypothesis remains untested. In the present study, 54 undergraduate students rated 40 jobs on several items, including the likelihood they would hire an obese person for each job. Multidimensional scaling showed a one-dimensional solution, labeled as physical activity, with participants less likely to hire obese persons for more active jobs. For hiring likelihood ratings for jobs at either end of the dimension appear to be most similar for men and individuals with more positive attitudes toward obese persons versus women and individuals with more negative attitudes toward obese persons. Implications for both theory and practice are discussed.
Housing conditions and mental health of orphans in South Africa
Marais, Lochner; Sharp, Carla; Pappin, Michele; Lenka, Molefi; Cloete, Jan; Skinner, Donald; Serekoane, Joe
2013-01-01
Literature from the developed world suggests that poor housing conditions and housing environments contribute to poor mental health outcomes, although research results are mixed. This study investigates the relationship between housing conditions and the socio-emotional health of orphans and vulnerable children (OVC) in South Africa. The results of the study are mainly inconclusive, although it is suggested that methodological considerations play a vital role in explaining the mixed results. However, a positive relationship was found between living in informal settlements and better socio-emotional health of the OVC. We speculate that the historical context of informal settlement formation in South Africa helps to explain this unexpected result. PMID:24013088

Can there be science without philosophy?
Nathan, Marco J; Brancaccio, Diego; Zoccali, Carmine
2016-12-01
Over the last few decades, philosophy has gained an increasingly bad reputation among working scientists. Prominent researchers have suggested, in various forms and degrees of mockery, that philosophy has little or nothing positive to contribute to science. This essay provides a response to these allegations. We begin by examining, and ultimately questioning, an influential argument purporting to undermine the significance of a philosophical approach to science. Next, we offer some biomedical examples where philosophical speculation plays a prominent role. We conclude by arguing that, when understood in the appropriate context, philosophical reflection is an important-indeed, integral-ingredient of healthy scientific inquiry. © The Author 2016.

Alexander the Great and West Nile virus encephalitis.
Marr, John S; Calisher, Charles H
2003-12-01
Alexander the Great died in Babylon in 323 BC. His death at age 32 followed a 2-week febrile illness. Speculated causes of death have included poisoning; assassination, and a number of infectious diseases. One incident, mentioned by Plutarch but not considered by previous investigators, may shed light on the cause of Alexander's death. The incident, which occurred as he entered Babylon, involved a flock of ravens exhibiting unusual behavior and subsequently dying at his feet. The inexplicable behavior of ravens is reminiscent of avian illness and death weeks before the first human cases of West Nile virus infection were identified in the United States. We posit that Alexander may have died of West Nile virus encephalitis.

Screened dipolar interactions in some molecular crystals
NASA Astrophysics Data System (ADS)
Munn, R. W.; Hurst, M.
1990-10-01
Screened dipole energies and dipole electric fields are calculated for the crystals of HCN, meta- and para-nitroaniline, the nonlinear optical compounds POM, MAP and DAN, meta-dinitrobenzene, and acetanilide. Only para-nitroaniline is centrosymmetric, but all the crystals have significant negative dipole energies (of the order of -20 kJ mol -1) except for POM and metadinitrobenzene, where they are positive but small in magnitude. Local dipole fields are of the order of 10 GV m -1. The results assume that surface charge annuls any macroscopic dipole field. It is speculated that the observed preponderance of centrosymmetric crystals of polar molecules may reflect a favourable dipole energy in the initial crystal nucleus rather than the macroscopic crystal.

During the 1990s and early 2000s, working-class and poor neighborhoods in San Francisco underwent dramatic economic and racial changes. One of the most heavily gentrified neighborhoods was the Mission District. As a result of local politics, housing and rental policies, real estate speculation, and development, thousands of Latina/o families were displaced. Using oral historical and ethnographic methodologies, print media, archival sources, and policy papers, this article traces the gentrification of the Mission District from the perspective of the Latina/o community. It also examines how gentrification was articulated as a positive turn within the larger public discourse on space and access.

A patient with xerostomia and xerophthalmia due to Sjögren's syndrome presented with acute motor-dominant polyneuropathy and multiple mononeuropathy with antiganglioside antibodies. Nerve conduction studies and a sural nerve biopsy revealed the neuropathy as a mixture of segmental demyelination and axonal degeneration. Positive results were obtained for several antiganglioside antibodies. Corticosteroid treatment proved effective. The neuropathy was considered to represent a mixture of polyneuropathy as Guillain-Barré syndrome and multiple mononeuropathy via Sjögren's syndrome. We speculate that Guillain-Barré syndrome occurred in the patient and Guillain-Barré syndrome itself activated multiple mononeuropathy via Sjögren's syndrome.

The Society of Thoracic Surgeons is the largest organization representing our specialty. At this time, escalating costs of medical care and the public demand for accountability have given rise to a number of issues that must be faced. The Society is in a position to lead the medical profession in addressing many of these issues. We must present a united front for our specialty and resolve problems involving our training programs, manpower, federal regulations regarding medical devices, and the Federal Trade Commission's position on advertising. Additionally, the organization must address the issue of a definition of physician competence as it relates to the certifying and recertifying process. Awareness of these problems by all members of the Society with the opportunity for open discussion is essential. It is vital that The Society of Thoracic Surgeons assume a visible positive position on these issues.

Exploring the notion of space coupling propulsion
NASA Technical Reports Server (NTRS)
Millis, Marc G.
1990-01-01
All existing methods of space propulsion are based on expelling a reaction mass (propellant) to induce motion. Alternatively, 'space coupling propulsion' refers to speculations about reacting with space-time itself to generate propulsive forces. Conceivably, the resulting increases in payload, range, and velocity would constitute a breakthrough in space propulsion. Such speculations are still considered science fiction for a number of reasons: (1) it appears to violate conservation of momentum; (2) no reactive media appear to exist in space; (3) no 'Grand Uniform Theories' exist to link gravity, an acceleration field, to other phenomena of nature such as electrodynamics. The rationale behind these objectives is the focus of interest. Various methods to either satisfy or explore these issues are presented along with secondary considerations. It is found that it may be useful to consider alternative conventions of science to further explore speculations of space coupling propulsion.
U.S. energy outlook and future energy impacts
NASA Astrophysics Data System (ADS)
Hamburger, Randolph John
2011-12-01
Energy markets were not immune to the 2007 financial crisis. Growth in the Indian and Chinese economies is placing strains on global energy supplies that could force a repeat of the 2008 price spike of $145/bbl for crude oil. Emerging market growth coupled with inefficiencies, frictions, and speculation in the energy markets has the potential to create drastic economic shocks throughout the world. The 2007 economic crisis has pushed back investment in energy projects where a low-growth scenario in world GDP could create drastic price increases in world energy prices. Without a long-term energy supply plan, the U.S. is destined to see growth reduced and its trade imbalances continue to deteriorate with increasing energy costs. Analysis of the U.S. natural gas futures markets and the impact of financial speculation on natural gas market pricing determined that financial speculation adds to price movements in the energy markets, which could cause violent swings in energy prices.

The Effect of Childhood Family Size on Fertility in Adulthood: New Evidence From IV Estimation.
Cools, Sara; Kaldager Hart, Rannveig
2017-02-01
Although fertility is positively correlated across generations, the causal effect of children's experience with larger sibships on their own fertility in adulthood is poorly understood. With the sex composition of the two firstborn children as an instrumental variable, we estimate the effect of sibship size on adult fertility using high-quality data from Norwegian administrative registers. Our study sample is all firstborns or second-borns during the 1960s in Norwegian families with at least two children (approximately 110,000 men and 104,000 women). An additional sibling has a positive effect on male fertility, mainly causing them to have three children themselves, but has a negative effect on female fertility at the same margin. Investigation into mediators reveals that mothers of girls shift relatively less time from market to family work when an additional child is born. We speculate that this scarcity in parents' time makes girls aware of the strains of life in large families, leading them to limit their own number of children in adulthood.
Psychophysiological Response Patterns to Affective Film Stimuli
Bos, Marieke G. N.; Jentgens, Pia; Beckers, Tom; Kindt, Merel
2013-01-01
Psychophysiological research on emotion utilizes various physiological response measures to index activation of the defense system. Here we tested 1) whether acoustic startle reflex (ASR), skin conductance response (SCR) and heart rate (HR) elicited by highly arousing stimuli specifically reflect a defensive state and 2) the relation between resting heart rate variability (HRV) and affective responding. In a within-subject design, participants viewed film clips with a positive, negative and neutral content. In contrast to SCR and HR, we show that ASR differentiated between negative, neutral and positive states and can therefore be considered as a reliable index of activation of the defense system. Furthermore, resting HRV was associated with affect-modulated characteristics of ASR, but not with SCR or HR. Interestingly, individuals with low-HRV showed less differentiation in ASR between affective states. We discuss the important value of ASR in psychophysiological research on emotion and speculate on HRV as a potential biological marker for demarcating adaptive from maladaptive responding.

Trastuzumab conjugates consisting of exatecan derivatives were prepared and their biological activities and physicochemical properties were evaluated. The ADCs showed strong efficacy and a low aggregation rate. The exatecan derivatives were covalently connected via a peptidyl spacer (Gly-Gly-Phe-Gly), which is assumed to be stable in circulation, and were cleaved by lysosomal enzymes following ADC internalization into tumor tissue. These anti-HER2 ADCs exhibited a high potency, specifically against HER2-positive cancer cell lines in vitro. The ADCs, bearing exatecan derivatives which have more than two methylene chains, exhibited superior cytotoxicity. It was speculated that steric hindrance of the cleavable amide moiety could be involved in the drug release. The adequate alkyl lengths of exatecan derivatives (13, 14, 15) were from two to four in terms of aggregation rate. The ADC having a hydrophilic moiety showed good efficacy in a HER2-positive and Trastuzumab-resistant breast carcinoma cell model in mice. Copyright © 2016 Elsevier Ltd. All rights reserved.

Theory and anatomical research suggest that the ability to mentally represent intended actions affect level of execution. This study presents preliminary data examining the association between children's ability to mentally represent action and general motor ability. Children aged 7- to 10 years were assessed for motor imagery ability using a simulation of reach task and motor ability via the Movement ABC-2. Motor ability values, based on percentile rank, ranged from 2 to 91, with a mean of 36. The overall correlation between mental representation and motor ability yielded a moderately positive relationship (r = .39). Interestingly, when looking at motor ability subcategories, only Balance was significant in the model, explaining 20% of the variance. These results provide preliminary evidence that children's motor ability and the ability to mentally represent action are associated in a positive direction. Furthermore, given the results for Balance, we speculate that there are clinical implications regarding work with potentially at-risk children. © 2011 Blackwell Publishing Ltd.

Three indicators derived from the Personality Assessment Inventory (PAI) Alcohol Problems scale (ALC)-tolerance/high consumption, loss of control, and negative social and psychological consequences-were subjected to taxometric analysis-mean above minus below a cut (MAMBAC), maximum covariance (MAXCOV), and latent mode factor analysis (L-Mode)-in 1,374 federal prison inmates (905 males, 469 females). Whereas the total sample yielded ambiguous results, the male subsample produced dimensional results, and the female subsample produced taxonic results. Interpreting these findings in light of previous taxometric research on alcohol abuse and dependence it is speculated that while alcohol use disorders may be taxonic in female offenders, they are probably both taxonic and dimensional in male offenders. Two models of male alcohol use disorder in males are considered, one in which the diagnostic features are categorical and the severity of symptomatology is dimensional, and one in which some diagnostic features (e.g., withdrawal) are taxonic and other features (e.g., social problems) are dimensional.
Mechanisms of nuclear pore complex assembly - two different ways of building one molecular machine.
Otsuka, Shotaro; Ellenberg, Jan
2018-02-01
The nuclear pore complex (NPC) mediates all macromolecular transport across the nuclear envelope. In higher eukaryotes that have an open mitosis, NPCs assemble at two points in the cell cycle: during nuclear assembly in late mitosis and during nuclear growth in interphase. How the NPC, the largest nonpolymeric protein complex in eukaryotic cells, self-assembles inside cells remained unclear. Recent studies have started to uncover the assembly process, and evidence has been accumulating that postmitotic and interphase NPC assembly use fundamentally different mechanisms; the duration, structural intermediates, and regulation by molecular players are different and different types of membrane deformation are involved. In this Review, we summarize the current understanding of these two modes of NPC assembly and discuss the structural and regulatory steps that might drive the assembly processes. We furthermore integrate understanding of NPC assembly with the mechanisms for rapid nuclear growth in embryos and, finally, speculate on the evolutionary origin of the NPC implied by the presence of two distinct assembly mechanisms. © 2017 The Authors.

Use of Multicopy Transposons Bearing Unfitness Genes in Weed Control: Four Example Scenarios
Gressel, Jonathan; Levy, Avraham A.
2014-01-01
We speculate that multicopy transposons, carrying both fitness and unfitness genes, can provide new positive and negative selection options to intractable weed problems. Multicopy transposons rapidly disseminate through populations, appearing in approximately 100% of progeny, unlike nuclear transgenes, which appear in a proportion of segregating populations. Different unfitness transgenes and modes of propagation will be appropriate for different cases: (1) outcrossing Amaranthus spp. (that evolved resistances to major herbicides); (2) Lolium spp., important pasture grasses, yet herbicide-resistant weeds in crops; (3) rice (Oryza sativa), often infested with feral weedy rice, which interbreeds with the crop; and (4) self-compatible sorghum (Sorghum bicolor), which readily crosses with conspecific shattercane and with allotetraploid johnsongrass (Sorghum halepense). The speculated outcome of these scenarios is to generate weed populations that contain the unfitness gene and thus are easily controllable. Unfitness genes can be under chemically or environmentally inducible promoters, activated after gene dissemination, or under constitutive promoters where the gene function is utilized only at special times (e.g. sensitivity to an herbicide). The transposons can be vectored to the weeds by introgression from the crop (in rice, sorghum, and Lolium spp.) or from planted engineered weed (Amaranthus spp.) using a gene conferring the degradation of a no longer widely used herbicide, especially in tandem with an herbicide-resistant gene that kills all nonhybrids, facilitating the rapid dissemination of the multicopy transposons in a weedy population.

Biomedicine is increasingly shaped by the speculative economical values of neoliberal capitalism. A key feature of this new bioeconomical regime is the patenting and circulation of organisms and tissue samples, allowing rapid commercialisation of bacterial, animal and human biomedical materials. When thinking about this trend towards commercialisation, we must consider the ways by which biomedicine has been shaped by economics to better address these exploitative relationships between medical researchers and subjects. These fraught questions of agency and exploitation can be addressed through the concept of clinical labour, a term Melinda Cooper and Catherine Waldby coined to discuss embodied forms of labour, including surrogacy, clinical trials and tissue economies, that dominate the post-Fordist biomedical economy. As a genre that extrapolates from contemporary technoscientific practices, science fiction is uniquely positioned to explore the ethics of biomedical research in this neoliberal speculative economy. Science fiction can give human-like agency and affect to microbial, animal and alien life, allowing modified organisms to speak and interact with their creators. Creating these dialogues between commercialised organisms and biomedical researchers makes clear the connections between contemporary clinical practice and exploitative labour relations, illuminating the more troubling aspects of the new bioeconomy and imagining alternatives to this system.

Can CT imaging features of ground-glass opacity predict invasiveness? A meta-analysis.
Dai, Jian; Yu, Guoyou; Yu, Jianqiang
2018-04-01
A meta-analysis was conducted to investigate the diagnostic performance of computed tomography (CT) imaging features of ground-glass opacity (GGO) to predict invasiveness. Two reviewers independently searched PubMed, Medline, Web of Science, Cochrane Embase and CNKI for relevant studies. CT imaging signs of bubble lucency, speculation, lobulated margin, and pleural indentation were used as diagnostic references to discriminate pre-invasive and invasive disease. The sensitivity, specificity, diagnostic odds ratio (DOR), summary receiver operating characteristic (SROC) curves, and the area under the SROC curve (AUC) were calculated to evaluate diagnostic efficiency. Twelve studies were finally included. Diagnostic performance ranged from 0.41 to 0.52 for sensitivity and 0.56 to 0.63 for specificity. The diagnostic positive and negative likelihood ratios ranged from 1.03 to 2.13 and 0.52 to 1.05, respectively. The DORs of the GGO CT features for discriminating invasive disease ranged from 1.02 to 4.00. The area under the ROC curve was also low, with a range of 0.60 to 0.67 for discriminating pre-invasive and invasive disease. The diagnostic value of a single CT imaging sign of GGO, such as bubble lucency, speculation, lobulated margin, or pleural indentation is limited for discriminating pre-invasive and invasive disease because of low sensitivity, specificity, and AUC. © 2018 The Authors.

Electromagnetic Tracking Navigation to Guide Radiofrequency Ablation (RFA) of a Lung Tumor
Amalou, Hayet; Wood, Bradford J.
2013-01-01
Radiofrequency ablation (RFA) may be an option for patients with lung tumors who have unresectable disease and are not suitable for available palliative modalities. RFA electrode positioning may take several attempts, necessitating multiple imaging acquisitions or continuous use of CT (Computed Tomography). Electromagnetic tracking utilizes miniature sensors integrated with RFA equipment to guide tools in real-time, while referencing to pre-procedure imaging. This technology was demonstrated successfully during a lung tumor ablation, and was more accurate at targeting the tumor, compared to traditional freehand needle insertion. It is possible, although speculative and anecdotal, that more accuracy could prevent unnecessary repositioning punctures and decrease radiation exposure. Electromagnetic tracking has theoretical potential to benefit minimally invasive interventions. PMID:23207535

Compartment syndrome complicating a ruptured Achilles tendon has previously been reported in a surgically treated patient. However--to our knowledge--this is the first report of compartment syndrome following conservative treatment. A 45-year-old man ruptured his Achilles tendon and elected to have treatment in an equinus cast. Three weeks later, he developed compartment syndrome and despite fasciotomy, required surgical debridement of his anterior compartment. Delay in both diagnosis and subsequent fasciotomy resulted in a poor outcome. Any suspicion of compartment syndrome mandates early compartmental pressure monitoring. The exact aetiology is uncertain but we speculate that the equinus position of his ankle combined with weight-bearing, was a major contributing factor.

Mechanisms of chiral discrimination by topoisomerase IV
Neuman, K. C.; Charvin, G.; Bensimon, D.; Croquette, V.
2009-01-01
Topoisomerase IV (Topo IV), an essential ATP-dependent bacterial type II topoisomerase, transports one segment of DNA through a transient double-strand break in a second segment of DNA. In vivo, Topo IV unlinks catenated chromosomes before cell division and relaxes positive supercoils generated during DNA replication. In vitro, Topo IV relaxes positive supercoils at least 20-fold faster than negative supercoils. The mechanisms underlying this chiral discrimination by Topo IV and other type II topoisomerases remain speculative. We used magnetic tweezers to measure the relaxation rates of single and multiple DNA crossings by Topo IV. These measurements allowed us to determine unambiguously the relative importance of DNA crossing geometry and enzymatic processivity in chiral discrimination by Topo IV. Our results indicate that Topo IV binds and passes DNA strands juxtaposed in a nearly perpendicular orientation and that relaxation of negative supercoiled DNA is perfectly distributive. Together, these results suggest that chiral discrimination arises primarily from dramatic differences in the processivity of relaxing positive and negative supercoiled DNA: Topo IV is highly processive on positively supercoiled DNA, whereas it is perfectly distributive on negatively supercoiled DNA. These results provide fresh insight into topoisomerase mechanisms and lead to a model that reconciles contradictory aspects of previous findings while providing a framework to interpret future results.

Some contingencies of spelling
Lee, Vicki L.; Sanderson, Gwenda M.
1987-01-01
This paper presents some speculation about the contingencies that might select standard spellings. The speculation is based on a new development in the teaching of spelling—the process writing approach, which lets standard spellings emerge collateral to a high frequency of reading and writing. The paper discusses this approach, contrasts it with behavior-analytic research on spelling, and suggests some new directions for this latter research based on a behavioral interpretation of the process writing approach to spelling.

As the dominant research paradigm within the construction of contemporary healthcare facilities, evidence-based design (EBD) will increasingly impact our expectations of what hospital architecture should be. Research methods within EBD focus on prototyping incremental advances and evaluating what has already been built. Yet medical care is a rapidly evolving system; changes to technology, workforce composition, patient demographics and funding models can create rapid and unpredictable changes to medical practice and modes of care. This dynamism has the potential to curtail or negate the usefulness of current best practice approaches. To imagine new directions for the role of the hospital in society, or innovative ways in which the built environment might support well-being, requires a model that can project beyond existing constraints. Speculative design employs a design-based research methodology to imagine alternative futures and uses the artefacts created through this process to enable broader critical reflection on existing practices. This paper examines the contribution of speculative design within the context of the paediatric hospital as a means of facilitating critical reflection regarding the design of new healthcare facilities. While EBD is largely limited by what has already been built, speculative design offers a complementary research method to meet this limitation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Kinetic models for goods exchange in a multi-agent market
NASA Astrophysics Data System (ADS)
Brugna, Carlo; Toscani, Giuseppe
2018-06-01
In this paper we introduce a system of kinetic equations describing an exchange market consisting of two populations of agents (dealers and speculators) expressing the same preferences for two goods, but applying different strategies in their exchanges. Similarly to the model proposed in Toscani et al. (2013), we describe the trading of the goods by means of some fundamental rules in price theory, in particular by using Cobb-Douglas utility functions for the exchange. The strategy of the speculators is to recover maximal utility from the trade by suitably acting on the percentage of goods which are exchanged. This microscopic description leads to a system of linear Boltzmann-type equations for the probability distributions of the goods on the two populations, in which the post-interaction variables depend from the pre-interaction ones in terms of the mean quantities of the goods present in the market. In this case, it is shown analytically that the strategy of the speculators can drive the price of the two goods towards a zone in which there is a branded utility for their group. Also, according to Toscani et al. (2013), the general system of nonlinear kinetic equations of Boltzmann type for the probability distributions of the goods on the two populations is described in details. Numerical experiments then show how the policy of speculators can modify the final price of goods in this nonlinear setting.

Pornography availability has increased in recent years, and while there is plenty of speculation about its effects, empirical investigation about how porn influences our lives has yielded mixed results. Additionally, few studies have addressed the effects of specific pornography characteristics. Past research has shown that male-centric pornography can be related to negative outcomes, while female-centric pornography is related to more positive outcomes, particularly in women. The present survey study examined the relationship between pornography characteristics (male- and female-centric) and the self-reported attitudes and sexual experiences of men and women. Participants in the full sample were 195 men and 310 women who completed an online questionnaire. Although effect sizes were small, women who reported viewing pornography with more female-centric features also reported more positive effects of pornography on sex life and perceptions of the other gender. While men were more likely than women to report negative effects relating to pornography use on these same measures, there were very few reported negative effects of pornography overall. These findings demonstrate a small association between the use of female-centric pornography and more positive outcomes, particularly for women.

The immunolocalization of the 14-3-3 eta isoform in the anterior horn cells (AHCs) of patients with sporadic amyotrophic lateral sclerosis (ALS) and controls was examined. Compared with the immunolocalization of other 14-3-3 isoforms, the immunolocalization of the 14-3-3 eta isoform was either synaptic at the periphery of AHCs, spindle-shaped in neurites, or granular in the cytoplasm. By double labeling with phosphorylated (p-)TDP-43, the transactivation response DNA binding protein of 43kDa (TDP-43) demonstrated frequent colocalization of the 14-3-3 eta isoform in granular structures (90%) and spindle-shaped structures (85.4%), but not in p-TDP-43-positive round inclusions. It is speculated that the 14-3-3 eta isoform is associated with not only a synaptic pathology of ALS but also TDP-positive small lesions in the cytoplasm and neurites. The absence of eta-like immunoreactivity in p-TDP-43-positive large inclusions suggests the restricted relevance of the 14-3-3 eta isoform during ALS pathogenesis to some phases of the p-TDP pathology.

Forecasted economic change and the self-fulfilling prophecy in economic decision-making
2017-01-01
This study addresses the self-fulfilling prophecy effect, in the domain of economic decision-making. We present experimental data in support of the hypothesis that speculative forecasts of economic change can impact individuals’ economic decision behavior, prior to any realized changes. In a within-subjects experiment, participants (N = 40) played 180 trials in a Balloon Analogue Risk Talk (BART) in which they could make actual profit. Simple messages about possible (positive and negative) changes in outcome probabilities of future trials had significant effects on measures of risk taking (number of inflations) and actual profits in the game. These effects were enduring, even though no systematic changes in actual outcome probabilities took place following any of the messages. Risk taking also found to be reflected in reaction times revealing increasing reaction times with riskier decisions. Positive and negative economic forecasts affected reaction times slopes differently, with negative forecasts resulting in increased reaction time slopes as a function of risk. These findings suggest that forecasted positive or negative economic change can bias people’s mental model of the economy and reduce or stimulate risk taking. Possible implications for media-fulfilling prophecies in the domain of the economy are considered. PMID:28334031

Population differentiation has proved to be effective for identifying loci under geographically localized positive selection, and has the potential to identify loci subject to balancing selection. We have previously investigated the pattern of genetic differentiation among human populations at 36.8 million genomic variants to identify sites in the genome showing high frequency differences. Here, we extend this dataset to include additional variants, survey sites with low levels of differentiation, and evaluate the extent to which highly differentiated sites are likely to result from selective or other processes. We demonstrate that while sites with low differentiation represent sampling effects rather than balancing selection, sites showing extremely high population differentiation are enriched for positive selection events and that one half may be the result of classic selective sweeps. Among these, we rediscover known examples, where we actually identify the established functional SNP, and discover novel examples including the genes ABCA12, CALD1 and ZNF804, which we speculate may be linked to adaptations in skin, calcium metabolism and defense, respectively. We identify known and many novel candidate regions for geographically restricted positive selection, and suggest several directions for further research.

Within social learning theory, positive alcohol expectancies represent motivation to drink and negative expectancies, motivation to restrain. It is also recognized that a subjective evaluation of expectancies ought to moderate their impact, although the evidence for this in social drinkers is problematic. This paper addresses the speculation that the moderating effect will be more evident in clinical populations. This study shows that (i) both expectancy and value reliably, independently and equally predict clients' abstinence survivorship following discharge from a treatment programme (and that this is almost entirely confined to the negative rather than positive terms). When (ii) expectancy evaluations are processed against expectancy through multiplicative composites (i.e. expectancy x value), their predictive power is only equivalent to either expectancy or value on its own. However (iii) when the multiplicative composite is assessed following the statistical guidelines advocated by Evans (1991) (i.e. within the same model as its constituents, expectancy and value) the increase in outcome variance explained by its inclusion is negligible and casts doubt upon its use in alcohol research. This does not appear to apply to value, however, and its possible role in treatment is discussed.

Cloud microphysical data obtained from G-1 aircraft flights over the southeastern pacific during the VOCALS-Rex field campaign were analyzed for evidence of entrainment mixing of dry air from above cloud top. Mixing diagram analysis was made for the horizontal flight data recorded at 1 Hz and 40 Hz. The dominant observed feature, a positive relationship between cloud droplet mean volume (V) and liquid water content (L), suggested occurrence of homogeneous mixing. On the other hand, estimation of the relevant scale parameters (i.e., transition length scale and transition scale number) consistently indicated inhomogeneous mixing. Importantly, the flight altitudes of the measurementsmore » were significantly below cloud top. We speculate that mixing of the entrained air near the cloud top may have indeed been inhomogeneous; but due to vertical circulation mixing, the correlation between V and L became positive at the measurement altitudes in mid-level of clouds, because during their descent, cloud droplets evaporate, faster in more diluted cloud parcels, leading to a positive correlation between V and L regardless of the mixing mechanism near the cloud top.« less
Effect of the home environment on motor and cognitive behavior of infants.
Miquelote, Audrei F; Santos, Denise C C; Caçola, Priscila M; Montebelo, Maria Imaculada de L; Gabbard, Carl
2012-06-01
Although information is sparse, research suggests that affordances in the home provide essential resources that promote motor and cognitive skills in young children. The present study assessed over time, the association between motor affordances in the home and infant motor and cognitive behavior. Thirty-two (32) infants were assessed for characteristics of their home using the Affordances in the Home Environment for Motor Development--Infant Scale and motor and cognitive behavior with the Bayley Scales of Infant and Toddler Development--III. Infant's home and motor behavior were assessed at age 9 months and 6 months later with the inclusion of cognitive ability. Results for motor ability indicated that there was an overall improvement in performance from the 1st to the 2nd assessment. We found significant positive correlations between the dimensions of the home (daily activities and play materials) and global motor performance (1st assessment) and fine-motor performance on the 2nd assessment. In regard to cognitive performance (2nd assessment), results indicated a positive association with fine-motor performance. Our results suggest that motor affordances can have a positive impact on future motor ability and speculatively, later cognitive behavior in infants. Copyright © 2012 Elsevier Inc.

Intrinsic properties of limb bud cells can be differentially reset.
Saiz-Lopez, Patricia; Chinnaiya, Kavitha; Towers, Matthew; Ros, Maria A
2017-02-01
An intrinsic timing mechanism specifies the positional values of the zeugopod (i.e. radius/ulna) and then autopod (i.e. wrist/digits) segments during limb development. Here, we have addressed whether this timing mechanism ensures that patterning events occur only once by grafting GFP-expressing autopod progenitor cells to the earlier host signalling environment of zeugopod progenitor cells. We show by detecting Hoxa13 expression that early and late autopod progenitors fated for the wrist and phalanges, respectively, both contribute to the entire host autopod, indicating that the autopod positional value is irreversibly determined. We provide evidence that Hoxa13 provides an autopod-specific positional value that correctly allocates cells into the autopod, most likely through the control of cell-surface properties as shown by cell-cell sorting analyses. However, we demonstrate that only the earlier autopod cells can adopt the host proliferation rate to permit normal morphogenesis. Therefore, our findings reveal that the ability of embryonic cells to differentially reset their intrinsic behaviours confers robustness to limb morphogenesis. We speculate that this plasticity could be maintained beyond embryogenesis in limbs with regenerative capacity. © 2017. Published by The Company of Biologists Ltd.

We are at the beginning of an era in which the pressure to secure the biggest possible "bang" for the health care "buck" is perhaps higher than it ever has been, on both sides of the Atlantic, and within the health policy discourse, incentives, for both professionals and patients, are occupying an increasingly prominent position. In this article, we consider issues related to motivating the professional and the patient to perform targeted actions, drawing on some of the evidence that has thus far been reported on experiences in the United Kingdom and the United States, and we present an admittedly somewhat speculative taxonomy of hypothesized effectiveness for some of the different methods by which each of these two broad types of incentives can be offered. We go on to summarize some of the problems of, and objections to, the use of incentives in health and health care, such as those relating to motivational crowding and gaming, but we conclude by positing that, following appropriate consideration, caution, and methodological and empirical investigation, health-related incentives, at least in some contexts, may contribute positively to the social good.

Various aspects of the impact of ozone depletion on the biosphere are assessed and discussed. Speculations on the factors which determine the extent and nature of biological damage due to an increased flux of ultra violet light are presented. It is concluded that a complete assessment must consider both direct effects (organisms) as well as indirect effects (ecosystems). The role of computer simulation of ecosystem models as a predictive tool is examined.

The 2006-2008 oil bubble: Evidence of speculation, and prediction
NASA Astrophysics Data System (ADS)
Sornette, Didier; Woodard, Ryan; Zhou, Wei-Xing
2009-04-01
We present an analysis of oil prices in USD and in other major currencies that diagnoses unsustainable faster-than-exponential behavior. This supports the hypothesis that the recent oil price run-up was amplified by speculative behavior of the type found during a bubble-like expansion. We also attempt to unravel the information hidden in the oil supply-demand data reported by two leading agencies, the US Energy Information Administration (EIA) and the International Energy Agency (IEA). We suggest that the found increasing discrepancy between the EIA and IEA figures provides a measure of the estimation errors. Rather than a clear transition to a supply restricted regime, we interpret the discrepancy between the IEA and EIA as a signature of uncertainty, and there is no better fuel than uncertainty to promote speculation! Our post-crash analysis confirms that the oil peak in July 2008 occurred within the expected 80% confidence interval predicted with data available in our pre-crash analysis.
Melatonin: A Mitochondrial Targeting Molecule Involving Mitochondrial Protection and Dynamics
Tan, Dun-Xian; Manchester, Lucien C.; Qin, Lilan; Reiter, Russel J.
2016-01-01
Melatonin has been speculated to be mainly synthesized by mitochondria. This speculation is supported by the recent discovery that aralkylamine N-acetyltransferase/serotonin N-acetyltransferase (AANAT/SNAT) is localized in mitochondria of oocytes and the isolated mitochondria generate melatonin. We have also speculated that melatonin is a mitochondria-targeted antioxidant. It accumulates in mitochondria with high concentration against a concentration gradient. This is probably achieved by an active transportation via mitochondrial melatonin transporter(s). Melatonin protects mitochondria by scavenging reactive oxygen species (ROS), inhibiting the mitochondrial permeability transition pore (MPTP), and activating uncoupling proteins (UCPs). Thus, melatonin maintains the optimal mitochondrial membrane potential and preserves mitochondrial functions. In addition, mitochondrial biogenesis and dynamics is also regulated by melatonin. In most cases, melatonin reduces mitochondrial fission and elevates their fusion. Mitochondrial dynamics exhibit an oscillatory pattern which matches the melatonin circadian secretory rhythm in pinealeocytes and probably in other cells. Recently, melatonin has been found to promote mitophagy and improve homeostasis of mitochondria. PMID:27999288

Northern long-eared bat day-roosting and prescribed fire in the central Appalachians
Ford, W. Mark; Silvis, Alexander; Johnson, Joshua B.; Edwards, John W.; Karp, Milu
2016-01-01
The northern long-eared bat (Myotis septentrionalis Trovessart) is a cavity-roosting species that forages in cluttered upland and riparian forests throughout the oak-dominated Appalachian and Central Hardwoods regions. Common prior to white-nose syndrome, the population of this bat species has declined to functional extirpation in some regions in the Northeast and Mid-Atlantic, including portions of the central Appalachians. Our long-term research in the central Appalachians has shown that maternity colonies of this species form non-random assorting networks in patches of suitable trees that result from long- and short-term forest disturbance processes, and that roost loss can occur with these disturbances. Following two consecutive prescribed burns on the Fernow Experimental Forest in the central Appalachians, West Virginia, USA, in 2007 to 2008, post-fire counts of suitable black locust (Robinia pseudoacacia L.; the most selected species for roosting) slightly decreased by 2012. Conversely, post-fire numbers of suitable maple (Acer spp. L.), primarily red maple (Acer rubrum L.), increased by a factor of three, thereby ameliorating black locust reduction. Maternity colony network metrics such as roost degree (use) and network density for two networks in the burned compartment were similar to the single network observed in unburned forest. However, roost clustering and degree of roost centralization was greater for the networks in the burned forest area. Accordingly, the short-term effects of prescribed fire are slightly or moderately positive in impact to day-roost habitat for the northern long-eared bat in the central Appalachians from a social dynamic perspective. Listing of northern long-eared bats as federally threatened will bring increased scrutiny of immediate fire impacts from direct take as well as indirect impacts from long-term changes to roosting and foraging habitat in stands being returned to historic fire-return conditions. Unfortunately, definitive impacts will remain speculative owing to the species’ current rarity and the paucity of forest stand data that considers tree condition or that adequately tracks snags spatially and temporally.
Stock market speculation: Spontaneous symmetry breaking of economic valuation
NASA Astrophysics Data System (ADS)
Sornette, Didier
2000-09-01
Firm foundation theory estimates a security's firm fundamental value based on four determinants: expected growth rate, expected dividend payout, the market interest rate and the degree of risk. In contrast, other views of decision-making in the stock market, using alternatives such as human psychology and behavior, bounded rationality, agent-based modeling and evolutionary game theory, expound that speculative and crowd behavior of investors may play a major role in shaping market prices. Here, we propose that the two views refer to two classes of companies connected through a "phase transition". Our theory is based on (1) the identification of the fundamental parity symmetry of prices (p→-p), which results from the relative direction of payment flux compared to commodity flux and (2) the observation that a company's risk-adjusted growth rate discounted by the market interest rate behaves as a control parameter for the observable price. We find a critical value of this control parameter at which a spontaneous symmetry-breaking of prices occurs, leading to a spontaneous valuation in absence of earnings, similarly to the emergence of a spontaneous magnetization in Ising models in absence of a magnetic field. The low growth rate phase is described by the firm foundation theory while the large growth rate phase is the regime of speculation and crowd behavior. In practice, while large "finite-time horizon" effects round off the predicted singularities, our symmetry-breaking speculation theory accounts for the apparent over-pricing and the high volatility of fast growing companies on the stock markets.

Inflammation and oxidative stress in obstructive sleep apnea syndrome.
Selmi, Carlo; Montano, Nicola; Furlan, Raffaello; Keen, Carl L; Gershwin, M Eric
2007-12-01
Similar to obesity, with which it is closely associated, obstructive sleep apnea syndrome (OSAS) is rapidly becoming a worldwide epidemic. Current knowledge of its pathogenesis has been significantly enriched by numerous experimental studies that have demonstrated an important role of oxidative stress and inflammation. Furthermore, new and exciting data strongly connect these two components in the perpetuation of the condition via the overexpression of nuclear factor kappaB. Experimental data support the hypothesis that nutrition might represent a promising future approach with antioxidants currently being good candidates for the modulation of cardiovascular sequelae, although weight reduction and controlled positive airway pressure remain the only established treatments for OSAS. We discuss herein the recent literature that illustrates these new paradigms and speculate on possible implications and future scenarios.

A man in his early forties who had undergone 3 years of unsuccessful treatment for infertility due to oligospermia and asthenospermia developed fever and bone pain in December 20XX. He was subsequently diagnosed with acute lymphocytic leukemia. Conventional cytogenetic analysis revealed Robertsonian translocation (RT) with der(13;14)(q10;q10) in addition to the Philadelphia (Ph) chromosome. Dasatinib and prednisolone induced complete remission (CR) with disappearance of the Ph chromosome. However, RT persisted despite achieving CR. We speculate that RT is possibly congenital in our present case and might also have been responsible for the aforementioned infertility. Hematologists should be aware of the possibility that congenital chromosomal disorders might be found incidentally through diagnostic chromosome analysis for leukemia.

According to our calculation, the volume of the Ca2 polyhedron increases by about 5.8% from fluorapatite to chlorapatite, but that of Ca1 polyhedron increases by only 0.59%. We speculate that the much greater size of the Ca2 polyhedron in chlorapatite may diminish the selectivity of this position for U and Th. The incorporation of U and Th into fluorapatite results in a decrease in the size of both Ca polyhedra, but the incorporation of U and Th into chlorapatite results in an increase in the volume of both Ca polyhedra. We suggest that the preference of U and Th formore » both Ca sites in chlorapatite is attributable to the large increase in size and distortion of the Ca2 polyhedron upon substitution of Cl for F.« less
Pyromania and the primal scene: a psychoanalytic comment on the work of Yukio Mishima.
Arlow, J A
1978-01-01
In the writings of the Japanese novelist, Yukio Mishima, primal scene experiences and derivative expressions of them recur persistently. The element of fire figures prominently in connection with the wish to wreak vengeance on the persons originally observed in the act of intercourse. As a destructive, attention-compelling spectacle, fire is a particularly suitable vehicle for this purpose. In Mishima's works, revenge takes the form of retaliation in kind: parental figures, or their surrogates, are put into the position of having to observe the child, or substitutes for him, in the act of sexual infidelity. These observations as well as clinical reports in the literature suggest some insights into fantasies of pyromania. They also make possible certain speculations concerning Misima's turbulent life and dramatic suicide.
Geomorphology and stratigraphy of Alba Patera, Mars
NASA Technical Reports Server (NTRS)
Schneeberger, Dale M.; Pieri, David C.
1991-01-01
Geomorphic and stratigraphic analysis of Alba Patera suggests a volcanic construct built by lavas with rheologic properties similar to basalts. A series of evolving eruptive styles is suggested by changes in morphology and inferred progressive reductions in flow volume with higher stratigraphic position. Alba Patera's volcanic history has been summarized into four main phases. The first is characterized by extensive flood like flows presumably erupted from fissures associated with the initial intrusion of magma into the region. The second phase is associated with the emplacement of pyroclastic rock, a more speculative interpretation. The third phase produced the voluminous tabular, crested, and undifferentiated flows, probably from a more centralized vent source. The fourth and last phase is marked the effusion of levee like flows and the collapse of the summit calderas and final graben formation.

A relationship between particular characteristics of dental occlusion and craniomandibular disorders (CMD) has been reported, while less attention has been focused on the possible effect of dysfunction of the masticatory system on head posture or cervicovertebral and craniofacial morphology. Natural head position roentgen-cephalograms of 16 young adults with complete dentition taken before and after stomatognathic treatment displayed an extended head posture, smaller size of the uppermost cervical vertebrae, decreased posterior to anterior face height ratio, and a flattened cranial base as compared with age- and sex-matched healthy controls. The lordosis of the cervical spine straightened after stomatognathic treatment. The results are an indication of the close interrelationship between the masticatory muscle system and the muscles supporting the head, and lead to speculation on the principles of treating craniomandibular disorders.

Electron donor-connecting cationic porphyrins meso-(1-naphthyl)-tris(N-methyl-p-pyridinio)porphyrin (1-NapTMPyP) and meso-(2-naphthyl)-tris(N-methyl-p-pyridinio)porphyrin (2-NapTMPyP) were designed and synthesized. DFT calculations speculate that the photoexcited states of 1- and 2-NapTMPyPs can be deactivated via intramolecular electron transfer from the naphthyl moiety to the porphyrin moiety. However, the quenching effect through the intramolecular electron transfer is insufficient, possibly due to the orthogonal position of the electron donor and the porphyrin ring and the relatively small driving force: Gibbs energies are 0.11 and 0.07 eV for 1- and 2-NapTMPyPs, respectively. It was speculated that more than 0.3 eV of the driving force is required to realize effective electron transfer in similar electron-donor connecting porphyrin systems. These porphyrins aggregated around the DNA strand, accelerating the deactivation of their excited singlet state and decreasing their photosensitized singlet oxygen-generating activities. In the presence of a sufficiently large concentration of DNA, these porphyrins can bind to a DNA strand stably, leading to an increased fluorescence quantum yield and lifetime. Singlet oxygen generation was also suppressed by the aggregation of porphyrins around DNA. Although the quantum yield of singlet oxygen generation was recovered in the presence of sufficient DNA, the singlet oxygen generated by DNA-binding porphyrins was significantly smaller than that without DNA. These results suggest that DNA-binding drugs limit the generation of photosensitized singlet oxygen by quenching the DNA strand.

Chaos theory may provide models for creativity and for the personality of the artist. A collection of speculative hypotheses examines the connection between art and such fundamentals of non-linear dynamics as iteration, dissipative processes, open systems, entropy, sensitivity to stimuli, autocatalysis, subsystems, bifurcations, randomness, unpredictability, irreversibility, increasing levels of organization, far-from-equilibrium conditions, strange attractors, period doubling, intermittency and self-similar fractal organization. Non-linear dynamics may also explain why certain individuals suffer mental disorders while others remain intact during a lifetime of sustained creative output.
Reader set encoding for directory of shared cache memory in multiprocessor system
Ahn, Dnaiel; Ceze, Luis H.; Gara, Alan; Ohmacht, Martin; Xiaotong, Zhuang
2014-06-10
In a parallel processing system with speculative execution, conflict checking occurs in a directory lookup of a cache memory that is shared by all processors. In each case, the same physical memory address will map to the same set of that cache, no matter which processor originated that access. The directory includes a dynamic reader set encoding, indicating what speculative threads have read a particular line. This reader set encoding is used in conflict checking. A bitset encoding is used to specify particular threads that have read the line.

Data from the Panel Study on Income Dynamics, excluding the low income Survey of Economic Opportunity, were used to test an empirical model of the relationship between US state tax exemption values and tax rates for couples and fertility. Income is held constant so that the real tax exemption value is affected by changes in tax rates, the price level, or the statutory value of the exemption. Prior research by Whittington et al. found a positive relationship between births and the federal exemption between 1979-83 for 294 households. The tax value of the exemption varies widely across states. There are 41 states with substantial personal income taxes, while seven states have no state personal income taxes. A very limited tax on personal income is collected in Tennessee, New Hampshire, and Connecticut. Pennsylvania has no dependency exemption. The range in exemption varies from $1500 in Georgia to $300 in Alabama. Tax credits in lieu of exemptions vary from $6 in Arkansas to $85 in Oregon. Tax rates also vary across states. The value of the exemption lowers the cost of a child and is not constant over time. Six models are specified. Model 1 uses combined state and federal exemptions. Models 2 and 3 use a lagged combined exemption value of one and two years. Models 4 and 6 use state exemptions separated from federal exemptions. Model 5 uses a lag of one year, and model 6 uses a lag of two years. The estimation results of the conditional logit (Chamberlain) Model 1 show a negative and significant coefficient, which suggests that exemptions are not an incentive for births. In Models 2 and 3, the coefficient is positive and significant. In Model 4, the pattern of Model 1 holds except the sign is positive. In Models 5 and 6, the federal exemption is positive and significant, and the state exemption is negative and significant. When substitution is made with the means of the predicted values for the exemption, Models 1-4 all become positive and significant. In models with income as a constant, income reduces the impact of the dependency exemption on fertility. Neither state or federal exemptions are a determinant of fertility but serve as a policy tool for motivating average family size.

The Alport syndrome is a hereditary glomerular disease linked to structural abnormalities of collagen IV. In a mouse model of Alport syndrome, the interstitial lymphocyte influx was important for disease progression. CXCR3 is a chemokine receptor involved in lymphocyte recruitment to the kidney. We hypothesized that CXCR3-positive T cells might be involved in human Alport syndrome. Immunohistochemistry was performed on formalin-fixed, paraffin-embedded biopsies from 17 patients with Alport syndrome, 10 with immunoglobulin A (IgA) nephropathy, and 11 healthy donor kidneys. We investigated the expression of the alpha5 chain of collagen IV to confirm the morphologic diagnosis, the chemokine receptor CXCR3 and CD3-positive T cells. Alport syndrome biopsies demonstrated a complete loss of the alpha5 chain of collagen IV from the glomerular basement membrane and the morphologic features consistent with Alport syndrome on electron microscopy. A prominent number of CXCR3-positive cells were found in the tubulointerstitium. Most of the CXCR3-positive cells were CD3-positive T cells, demonstrated by double-labeling in selected biopsies. The number of CXCR3-positive cells in kidneys with Alport syndrome correlated with serum creatinine (P < .05) and with morphologic features of a progressive disease (eg, interstitial fibrosis, glomerulosclerosis, and tubular atrophy). The severity of interstitial CXCR3-positive cell influx was similar in Alport syndrome as compared to immunoglobulin A nephropathy. The noninflammatory glomerular lesion of Alport syndrome is associated with prominent interstitial accumulation of CD3- and CXCR3-positive lymphocytes. The degree of infiltration correlated with renal function. We speculate that targeting T lymphocytes, for example, by CXCR3 blocking agents, might be a novel approach to inhibit disease progression in patients with Alport syndrome.

Feedback Valence Affects Auditory Perceptual Learning Independently of Feedback Probability
Amitay, Sygal; Moore, David R.; Molloy, Katharine; Halliday, Lorna F.
2015-01-01
Previous studies have suggested that negative feedback is more effective in driving learning than positive feedback. We investigated the effect on learning of providing varying amounts of negative and positive feedback while listeners attempted to discriminate between three identical tones; an impossible task that nevertheless produces robust learning. Four feedback conditions were compared during training: 90% positive feedback or 10% negative feedback informed the participants that they were doing equally well, while 10% positive or 90% negative feedback informed them they were doing equally badly. In all conditions the feedback was random in relation to the listeners’ responses (because the task was to discriminate three identical tones), yet both the valence (negative vs. positive) and the probability of feedback (10% vs. 90%) affected learning. Feedback that informed listeners they were doing badly resulted in better post-training performance than feedback that informed them they were doing well, independent of valence. In addition, positive feedback during training resulted in better post-training performance than negative feedback, but only positive feedback indicating listeners were doing badly on the task resulted in learning. As we have previously speculated, feedback that better reflected the difficulty of the task was more effective in driving learning than feedback that suggested performance was better than it should have been given perceived task difficulty. But contrary to expectations, positive feedback was more effective than negative feedback in driving learning. Feedback thus had two separable effects on learning: feedback valence affected motivation on a subjectively difficult task, and learning occurred only when feedback probability reflected the subjective difficulty. To optimize learning, training programs need to take into consideration both feedback valence and probability. PMID:25946173

Using the 125-day baboon model of bronchopulmonary dysplasia treated with prenatal steroid and exogenous surfactant, we hypothesized that a delay of extubation from low tidal volume positive pressure ventilation to nasal continuous positive airway pressure at 5 days (delayed nasal continuous positive airway pressure group) would not induce more lung injury when compared with baboons aggressively weaned to nasal continuous positive airway pressure at 24 hours (early nasal continuous positive airway pressure group), because both received positive pressure ventilation. After delivery by cesarean section at 125 days (term: 185 days), infants received 2 doses of Curosurf (Chiesi Farmaceutica S.p.A., Parma, Italy) and daily caffeine citrate. The delay in extubation to 5 days resulted in baboons in the delayed nasal continuous positive airway pressure group having a lower arterial to alveolar oxygen ratio, high PaCO2, and worse respiratory function. The animals in the delayed nasal continuous positive airway pressure group exhibited a poor respiratory drive that contributed to more reintubations and time on mechanical ventilation. A few animals in both groups developed necrotizing enterocolitis and/or sepsis, but infectious pneumonias were not documented. Cellular bronchiolitis and peribronchiolar alveolar wall thickening were more frequently seen in the delayed nasal continuous positive airway pressure group. Bronchoalveolar lavage levels of interleukin-6, interleukin-8, monocyte chemotactic protein-1, macrophage inflammatory protein-1 alpha, and growth-regulated oncogene-alpha were significantly increased in the delayed nasal continuous positive airway pressure group. Standard and digital morphometric analyses showed no significant differences in internal surface area and nodal measurements between the groups. Platelet endothelial cell adhesion molecule vascular staining was not significantly different between the 2 nasal continuous positive airway pressure groups. Volutrauma and/or low-grade colonization of airways secondary to increased reintubations and ventilation times are speculated to play causative roles in the delayed nasal continuous positive airway pressure group findings.
Tonsillectomy and infectious mononucleosis.
Sumaya, C V; Downey, K; Ullis, K C
1978-01-01
Tonsillar tissue may be the primary site of infection with Epstein-Barr virus (EBV), the etiologic agent of classical infectious mononucleosis (IM). Therefore, a retrospective study of the association between tonsillectomy and IM was performed in a college student population. In the first part of the study, tonsillectomy rates were compared between 164 IM-positive students and 164 student controls who attended UCLA in 1972-1975. Although it was determined that the development of IM during college years was statistically less commin in tonsillectomized students, the difference was not inordinately large and probably had no significant biologic meaning. The authors speculate that the difference was due to the greater likelihood, and greater yield, in considering the diagnosis of IM in young adults with enlarged, inflamed tonsils. In support of this is the fact that IM-positive students who had received a prior tonsillectomy usually had the surgical procedure performed at a younger age than the control group. Conceivably, tonsillar ablation in the very young is more liable to result in incomplete removal and eventual regrowth of this tissue. Indeed, six IM-positive students who had received a tonsillectomy at six years of age or less were found to have exudate in tonsillar fossae or pillars during their IM episode. In the second part of the study, clinical and laboratory measures were found to be similar between a larger group of IM-positive students with or without a history of prior tonsillectomy.

...The Office of the Comptroller of the Currency (OCC), Board of Governors of the Federal Reserve System (Board), and Federal Deposit Insurance Corporation (FDIC) are revising their market risk capital rules to better capture positions for which the market risk capital rules are appropriate; reduce procyclicality; enhance the rules' sensitivity to risks that are not adequately captured under current methodologies; and increase transparency through enhanced disclosures. The final rule does not include all of the methodologies adopted by the Basel Committee on Banking Supervision for calculating the standardized specific risk capital requirements for debt and securitization positions due to their reliance on credit ratings, which is impermissible under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Instead, the final rule includes alternative methodologies for calculating standardized specific risk capital requirements for debt and securitization positions.

Motility is the feature that allows spermatozoa to actively reach and penetrate the female gamete during fertilization. When this function is altered, and especially decreased, troubles in conceiving may occur. In this study, we demonstrated that treating fertile women with myo-inositol (MI) vaginal suppositories ameliorated their partners' sperm motility and also positively affected their conceiving capacity, without changes in cervical mucus structural and biochemical characteristics. Indeed, by means of the postcoital test on female cervical mucus, a significant improvement especially in progressive sperm motility was recorded after MI suppository use. Concomitantly, after MI treatment, a reduction of immotile spermatozoa percentage was observed. Importantly, MI vaginal supplementation positively correlated with a pregnancy for 5 of the 50 couples enrolled in the study, leading us to speculate that this substance may substantially contribute to create in the cervical mucus an ideal milieu that makes spermatozoa more motile and functionally able to fertilize. Even though the detailed mechanism is still unclear, these results should encourage MI vaginal use for the clinical improvement of male infertility, through their partners.

Cationic polyimines polymerized through aromatically conjugated bis-imine linkages and intra-molecular cross-linking were found to be a new class of effective transfection materials for their flexibility in structural optimization, responsiveness to intracellular environment, the ability to facilitate endosome escape and cytosol release of the nucleic acids, as well as self-metabolism. When three phthalaldehydes of different substitution positions were used to polymerize highly branched low-molecular weight polyethylenimine (PEI 1.8K), the product through ortho-phthalimines (named PPOP) showed significantly higher transfection activity than its two tere- and iso-analogs (named PPTP and PPIP). Physicochemical characterization confirmed the similarity of three polyimines in pH-responded degradability, buffer capacity, as well as the size and Zeta potential of the polyplexes formed from the polymers. A mechanistic speculation may be that the ortho-positioned bis-imine linkage of PPOP may only lead to the straight trans-configuration due to steric hindrance, resulting in larger loops of intra-polymer cross-linking and more flexible backbone.

Application of high-brightness LEDs in aircraft position lights
NASA Astrophysics Data System (ADS)
Machi, Nicolo; Mangum, Scott; Singer, Jeffrey M.
2004-10-01
Solid state lighting devices have made their way into a number of niche markets and continue to make inroads into other markets as their price / performance ratios improve. One of these markets is aviation lighting. Although this paper will focus on the use of LEDs for aircraft position lights, much of the discussion is applicable to other installations on the interior and exterior of the aircraft. The color, light distribution and intensity levels for a position light are all closely regulated through Code of Federal Regulation (CFR; formerly Federal Aviation Regulation (FAR)) documents. These lighting requirements, along with harsh thermal and environmental requirements, drive the design. In this paper, we will look at these requirements and discuss what is required in order to use LEDs for this type of application. We will explore the optical, thermal and electrical issues associated with the use of LEDs for position lights and examine the specific case study of the Astreon forward position lights. Finally, we will discuss some of the challenges that we see with solid state lighting in current and future aircraft applications.
Hypervariable and highly divergent intron-exon organizations in the chordate Oikopleura dioica.
Edvardsen, Rolf B; Lerat, Emmanuelle; Maeland, Anne Dorthea; Flåt, Mette; Tewari, Rita; Jensen, Marit F; Lehrach, Hans; Reinhardt, Richard; Seo, Hee-Chan; Chourrout, Daniel

Oikopleura dioica is a pelagic tunicate with a very small genome and a very short life cycle. In order to investigate the intron-exon organizations in Oikopleura, we have isolated and characterized ribosomal protein EF-1alpha, Hox, and alpha-tubulin genes. Their intron positions have been compared with those of the same genes from various invertebrates and vertebrates, including four species with entirely sequenced genomes. Oikopleura genes, like Caenorhabditis genes, have introns at a large number of nonconserved positions, which must originate from late insertions or intron sliding of ancient insertions. Both species exhibit hypervariable intron-exon organization within their alpha-tubulin gene family. This is due to localization of most nonconserved intron positions in single members of this gene family. The hypervariability and divergence of intron positions in Oikopleura and Caenorhabditis may be related to the predominance of short introns, the processing of which is not very dependent upon the exonic environment compared to large introns. Also, both species have an undermethylated genome, and the control of methylation-induced point mutations imposes a control on exon size, at least in vertebrate genes. That introns placed at such variable positions in Oikopleura or C. elegans may serve a specific purpose is not easy to infer from our current knowledge and hypotheses on intron functions. We propose that new introns are retained in species with very short life cycles, because illegitimate exchanges including gene conversion are repressed. We also speculate that introns placed at gene-specific positions may contribute to suppressing these exchanges and thereby favor their own persistence.
On Medicaid and the Affordable Care Act in Connecticut
Manthous, Constantine A.; Sofair, Andre N.
2014-01-01
Background: Medicaid is the federal program, administered by states, for health care for the poor. The Affordable Care Act (ACA) has added a large number of new recipients to this program. Hypothesis: Medicaid programs in some, if not many, states do not provide patients uniform access to subspecialty care guaranteed by the federal statutes. Insofar as the ACA does not address this pre-existing “sub-specialty gap” and more patients are now covered by Medicaid under the ACA, the gap is likely to increase and may contribute to disparities of health care access and outcomes. Methods: A brief description of previous studies demonstrating or suggesting a subspecialty gap in Medicaid services is accompanied by perspectives of the authors, using published literature — most notably the Denver, Colorado health care system — to propose various solutions that may be deployed to address gaps in subspecialty coverage. Results: All published studies describing the Medicaid subspecialty gap are qualitative, survey designs. There are no authoritative objective data regarding the exact prevalence of gaps for each subspecialty in each state. However, surveys of caregivers suggest that gaps were prevalent in the United States prior to initiation of the ACA. Even fewer papers have addressed solutions (in light of the paucity of data describing the magnitude of the problem), and proposed solutions remain speculative and not grounded in objective data. Conclusions: There is reason to believe that a substantial proportion of U.S. citizens — those who are guaranteed a full complement of health services through Medicaid — have difficult or no access to some subspecialty services, many of which other citizens take for granted. This problem deserves greater attention to verify its existence, quantify its magnitude, and develop solutions. PMID:25506291

We study how the approach grounded on non-extensive statistical physics can be applied to describe and distinguish different stages of the stock and money market development. A particular attention is given to asymmetric behavior of fat tailed distributions of positive and negative returns. A new method to measure this asymmetry is proposed. It is based on the value of the non-extensive Tsallis parameter q. The new quantifier of the relative asymmetry level between tails in terms of the Tsallis parameters q± is provided to analyze the effect of memory in data caused by nonlinear autocorrelations. The presented analysis takes into account data of separate stocks from the main developing stock market in Europe, i.e., the Warsaw Stock Exchange (WSE) in Poland and—for comparison—data from the most mature money market (Forex). It is argued that the proposed new quantifier is able to describe the stage of market development and its robustness to speculation. The main strength is put on a description and interpretation of the asymmetry between statistical properties of positive and negative returns for various stocks and for diversified time-lags Δt of data counting. The particular caution in this context is addressed to the difference between intraday and interday returns. Our search is extended to study memory effects and their dependence on the quotation frequency for similar large companies—owners of food-industrial retail supermarkets acting on both Polish and European markets (Eurocash, Jeronimo-Martins, Carrefour, Tesco)—but traded on various European stock markets of diversified economical maturity (respectively in Warsaw, Lisbon, Paris and London). The latter analysis seems to indicate quantitatively that stocks from the same economic sector traded on different markets within European Union (EU) may be a target of diversified level of speculations involved in trading independently on the true economic situation of the company. Our work thus gives indications that the statement:” where you are is more important than who you are” is true on trading markets. PMID:29190696

Most dendrochronological studies focus on cores sampled from standard positions (main stem, breast height), yet vertical gradients in hydraulic constraints and priorities for carbon allocation may contribute to different growth sensitivities with position. Using cores taken from five positions (coarse roots, breast height, base of live crown, mid-crown branch and treetop), we investigated how radial growth sensitivity to climate over the period of 1895-2008 varies by position within 36 large ponderosa pines (Pinus ponderosa Dougl.) in northern Arizona. The climate parameters investigated were Palmer Drought Severity Index, water year and monsoon precipitation, maximum annual temperature, minimum annual temperature and average annual temperature. For each study tree, we generated Pearson correlation coefficients between ring width indices from each position and six climate parameters. We also investigated whether the number of missing rings differed among positions and bole heights. We found that tree density did not significantly influence climatic sensitivity to any of the climate parameters investigated at any of the sample positions. Results from three types of analyses suggest that climatic sensitivity of tree growth varied with position height: (i) correlations of radial growth and climate variables consistently increased with height; (ii) model strength based on Akaike's information criterion increased with height, where treetop growth consistently had the highest sensitivity and coarse roots the lowest sensitivity to each climatic parameter; and (iii) the correlation between bole ring width indices decreased with distance between positions. We speculate that increased sensitivity to climate at higher positions is related to hydraulic limitation because higher positions experience greater xylem tensions due to gravitational effects that render these positions more sensitive to climatic stresses. The low sensitivity of root growth to all climatic variables measured suggests that tree carbon allocation to coarse roots is independent of annual climate variability. The greater number of missing rings in branches highlights the fact that canopy development is a low priority for carbon allocation during poor growing conditions.

There is growing evidence that mirror neurons, initially discovered over two decades ago in the monkey, are present in the human brain. In the monkey, mirror neurons characteristically fire not only when it is performing an action, such as grasping an object, but also when observing a similar action performed by another agent (human or monkey). In this review we discuss the origin, cortical distribution and possible functions of mirror neurons as a background to exploring their potential relevance in amyotrophic lateral sclerosis (ALS). We have recently proposed that ALS (and the related condition of frontotemporal dementia) may be viewed as a failure of interlinked functional complexes having their origins in key evolutionary adaptations. This can include loss of the direct projections from the corticospinal tract, and this is at least part of the explanation for impaired motor control in ALS. Since, in the monkey, corticospinal neurons also show mirror properties, ALS in humans might also affect the mirror neuron system. We speculate that a defective mirror neuron system might contribute to other ALS deficits affecting motor imagery, gesture, language and empathy.

This paper examines using housing supply as proxy to house prices, the causal relationship on house prices among 8 states in Malaysia by applying the Engle-Granger cointegration test and Granger causality test approach. The target states are Perak, Selangor, Penang, Federal Territory of Kuala Lumpur (WPKL or Kuala Lumpur), Kedah, Negeri Sembilan, Sabah and Sarawak. The primary aim of this study is to estimate how long (in months) house prices in Perak lag behind that of Selangor, Penang and WPKL. We classify the 8 states into two categories - developed and developing states. We use Engle-Granger cointegration test and Granger causality test to examine the long run and short run equilibrium relationship among the two categories.. It is found that the causal relationship is bidirectional in Perak and Sabah, Perak and Selangor while it is unidirectional for Perak and Sarawak, Perak and Penang, Perak and WPKL. The speed of deviation adjustment is about 273%, suggesting that the pricing dynamic of Perak has a 32- month or 2 3/4- year lag behind that of WPKL, Selangor and Penang. Such information will be useful to investors, house buyers and speculators.
Speculating on health: public health meets finance in 'health impact bonds'.
Rowe, Rachel; Stephenson, Niamh
2016-11-01
Where modern public health developed techniques to calculate probability, potentiality, risk and uncertainty, contemporary finance introduces instruments that redeploy these. This article traces possibilities for interrogating the connection between health and financialisation as it is arising in one particular example - the health impact bond. It locates the development of this very recent financial innovation in an account of public health's role within governance strategies over the 20th century to the present. We examine how social impact bonds for chronic disease prevention programmes bring two previously distinct ways of thinking about and addressing risk into the same domain. Exploring the derivative-type properties of health impact bonds elucidates the financial processes of exchange, hedging, bundling and leveraging. As tools for speculation, the functions of health impact bonds can be delinked from any particular outcome for participants in health interventions. How public health techniques for knowing and acting on risks to population health will contest, rework or be subsumed within finance's speculative response to risk, is to be seen. © 2016 Foundation for the Sociology of Health & Illness.
Phosphorous Nutritional Level, Carbohydrate Reserves and Flower Quality in Olives.
Erel, Ran; Yermiyahu, Uri; Yasuor, Hagai; Cohen Chamus, Dan; Schwartz, Amnon; Ben-Gal, Alon; Dag, Arnon
2016-01-01
The olive tree is generally characterized by relatively low final fruit set consequential to a significant rate of undeveloped pistils, pistil abortion, and flower and fruitlet abscission. These processes are acknowledged to be governed by competition for resources between the developing vegetative and reproductive organs. To study the role of phosphorus (P) nutritional level on reproductive development, trees were grown under four levels of P for three years in large containers. Phosphorus nutritional level was positively related to rate of reproductive bud break, inflorescence weight, rate of hermaphrodite flowers, pistil weight, fruitlet persistence, fruit set and the consequential total number of fruits. The positive impact of P nutrition on the productivity parameters was not related to carbohydrate reserves or to carbohydrate transport to the developing inflorescence. Phosphorous deficient trees showed significant impairment of assimilation rate, and yet, carbohydrates were accumulated in inflorescences at levels comparable to or higher than trees receiving high P. In contrast to female reproductive organs, pollen viability was consistently higher in P deficient trees, possibly due to the enhanced carbohydrate availability. Overall, the positive effect of P on female reproductive development was found to be independent of the total carbohydrate availability. Hence, P is speculated to have a direct influence on reproductive processes.
An investigation of immune system disorder as a "marker" for anomalous dominance.
Rich, D A; McKeever, W F
1990-01-01
Geschwind and Galaburda (1987) proposed that immune disorder (ID) susceptibility, along with left handedness and familial sinistrality (FS), is a "marker" for anomalous dominance. The theory predicts lesser left lateralization for language processes, lessened left hemisphere abilities, and enhanced right hemisphere abilities. We assessed language laterality (dichotic consonant vowel task) and performances on spatial and verbal tasks. Subjects were 128 college students. The factors of handedness, sex, FS, and immune disorder history (negative or positive) were perfectly counterbalanced. Left-handers were significantly less lateralized for language and scored lower than right-handers on the spatial tasks. Females scored lower on mental rotation than males, but performed comparably to males on the spatial relations task. The only effect of ID was by way of interaction with FS on both spatial tasks--subjects who were either negative or positive on both FS and ID status factors scored significantly higher than subjects negative for one but positive for the other factor. A speculative explanatory model for this interaction was proposed. The model incorporates the notion that FS and ID factors are comparably correlated, but in opposite directions, with hormonal factors implicated by other research as relevant for spatial ability differences. Finally, no support for the "anomalous dominance" hypothesis predictions was found.
Order and chaos in the one-dimensional ϕ4 model: N-dependence and the Second Law of Thermodynamics
NASA Astrophysics Data System (ADS)
Hoover, William Graham; Aoki, Kenichiro
2017-08-01
We revisit the equilibrium one-dimensional ϕ4 model from the dynamical systems point of view. We find an infinite number of periodic orbits which are computationally stable. At the same time some of the orbits are found to exhibit positive Lyapunov exponents! The periodic orbits confine every particle in a periodic chain to trace out either the same or a mirror-image trajectory in its two-dimensional phase space. These ;computationally stable; sets of pairs of single-particle orbits are either symmetric or antisymmetric to the very last computational bit. In such a periodic chain the odd-numbered and even-numbered particles' coordinates and momenta are either identical or differ only in sign. ;Positive Lyapunov exponents; can and do result if an infinitesimal perturbation breaking a perfect two-dimensional antisymmetry is introduced so that the motion expands into a four-dimensional phase space. In that extended space a positive exponent results. We formulate a standard initial condition for the investigation of the microcanonical chaotic number dependence of the model. We speculate on the uniqueness of the model's chaotic sea and on the connection of such collections of deterministic and time-reversible states to the Second Law of Thermodynamics.
Benign intestinal glandular lesions in the vagina: a possible correlation with implantation.
Lu, Weiwei; Zhang, Xiaofei; Lu, Bingjian
2016-06-17
Enteric-type glandular lesions are extremely rare in the vagina. Their histological origin remains a matter of speculation at present. We review two rectal mucosal prolapse-like polyps and one intestinal-type adenosis in the vagina. Case 1, a 64-year-old woman, presented with a vaginal polypoid lesion with a size of 4 × 3 × 3 cm. Case 2, an 8-year-old girl, had a 1.5 × 1.5 × 0.8-cm pedunculated polyp in the vaginal navicular fossa and a clinically suspected rectovaginal fistula. Case 1 and 3 had an obsolete severe perineal laceration. On histopathological examination, cases 1 and 2 resembled rectal mucosal prolapse or inflammatory cloacogenic polyp (rectal mucosal prolapse-like polyp). Case 3 had an incidental intestinal-type adenosis in the removed vaginal wall. Immunohistochemistry confirmed the intestinal differentiation in all 3 lesions by showing diffuse CDX2-positive, CK20-positive, and scattered chromogranin A-positive neuroendocrinal cells in the lower compartment of the crypt. In summary, we report herein three unusual cases of benign intestinal-type glandular lesions in the vagina including two rectal mucosal prolapse-like polyps and one case of intestinal-type adenosis, and discuss possibilities for their histogenetic basis.

Should consumers be able to obtain information about their own bodies, even if it has no proven medical value? Direct-to-consumer ("DTC") genomic companies offer consumers two services: generation of the consumer's personal genetic sequence, and interpretation of that sequence in light of current research. Concerned that consumers will misunderstand genomic information and make ill-advised health decisions, regulators, legislators and scholars have advocated restricted access to DTC genomic services. The Food and Drug Administration, which has historically refrained from regulating most genetic tests, has announced its intent to treat DTC genomic services as medical devices because they make "medical claims." This Article argues that FDA regulation of genomic services as medical devices would be counterproductive. Clinical laboratories conducting genetic tests are already overseen by a federal regime administered by the Centers for Medicare and Medicaid Services. While consumers and clinicians would benefit from clearer communication of test results and their health implications, FDA's gatekeeping framework is ill-suited to weigh the safety and efficacy of genomic information that is not medically actionable in traditional ways. Playing gatekeeper would burden FDA's resources, conflict with the patient-empowering policies promoted by personalized medicine initiatives, impair individuals' access to information in which they have powerful autonomy interests, weaken novel participatory research infrastructures, and set a poor precedent for the future regulation of medical information. Rather than applying its risk-based regulatory framework to genetic information, FDA should ameliorate regulatory uncertainty by working with the Federal Trade Commission and Centers for Medicare and Medicaid Services to ensure that DTC genomic services deliver analytically valid data, market and implement their services in a truthful manner, and fully disclose the limitations of their services. Federal agencies with relevant expertise should collaborate on standards and best practices for interpreting genetic information in light of scientific uncertainty, and an adverse event reporting system should be established to collect empirical data verifying or disproving the speculative harms resulting from individual access to genetic information. Most of all, FDA should take advantage of this opportunity to adapt its regulatory process to an increasingly informational health ecosystem.
On the maximum drawdown during speculative bubbles

2007-08-01
A taxonomy of large financial crashes proposed in the literature locates the burst of speculative bubbles due to endogenous causes in the framework of extreme stock market crashes, defined as falls of market prices that are outlier with respect to the bulk of drawdown price movement distribution. This paper goes on deeper in the analysis providing a further characterization of the rising part of such selected bubbles through the examination of drawdown and maximum drawdown movement of indices prices. The analysis of drawdown duration is also performed and it is the core of the risk measure estimated here.
Population movement in post-colonial Fiji: review and speculation.
Bedford, R D
1988-03-01
"This paper examines developments in population movement [in Fiji] between 1970 and 1986 with particular reference to an acceleration in levels of migration overseas by Indians and an exodus of Fijians from rural village communities for towns on Viti Levu and Vanua Levu. Trends in internal and international migration are evaluated at a range of spatial scales--national, regional and local. Some speculation on the effect of political and economic changes since May 1987 on these population movements attempts to provide a contemporary perspective on demographic developments over the last 15 years." Data are from the 1986 Fijian census. excerpt

Principal components analysis was performed using Federal Employee Viewpoint Survey (FEVS) data (N = 392,752) to extract variables representing worker well-being constructs. Confirmatory factor analysis was performed to verify factor structure. To validate the WRWB index, we used multiple regression analysis to examine relationships with burnout associated outcomes. Principal Components Analysis identified three positive psychology constructs: "Work Positivity", "Co-worker Relationships", and "Work Mastery". An 11 item index explaining 63.5% of variance was achieved. The structural equation model provided a very good fit to the data. Higher WRWB scores were positively associated with all three employee experience measures examined in regression models. The new WRWB index shows promise as a valid and widely accessible instrument to assess worker well-being.

A glutamate-sensitive inward current (Iglu) is described in rat cerebellar granule neurons and related to a glutamate transport mechanism. We examined the features of Iglu using the patch-clamp technique. In steady-state conditions the Iglu measured 8.14 1.9 pA. Iglu was identified as a voltage-dependent inward current showing a strong rectification at positive potentials. L-Glutamate activated the inward current in a dose-dependent manner, with a half-maximal effect at about 18 M and a maximum increase of 51.2 4.4%. The inward current was blocked by the presence of dihydrokainate (0.5 mM), shown by others to readily block the GLT1 isoform. We thus speculate that Iglu could be attributed to the presence of a native glutamate transporter in cerebellar granule neurons.
Age of Palos Verdes submarine debris avalanche, southern California
Normark, W.R.; McGann, M.; Sliter, R.
2004-01-01
The Palos Verdes debris avalanche is the largest, by volume, late Quaternary mass-wasted deposit recognized from the inner California Borderland basins. Early workers speculated that the sediment failure giving rise to the deposit is young, taking place well after sea level reached its present position. A newly acquired, closely-spaced grid of high-resolution, deep-tow boomer profiles of the debris avalanche shows that the Palos Verdes debris avalanche fills a turbidite leveed channel that extends seaward from San Pedro Sea Valley, with the bulk of the avalanche deposit appearing to result from a single failure on the adjacent slope. Radiocarbon dates from piston-cored sediment samples acquired near the distal edge of the avalanche deposit indicate that the main failure took place about 7500 yr BP. ?? 2003 Elsevier B.V.

Is there evidence to support a forefoot strike pattern in barefoot runners? A review.
Lorenz, Daniel S; Pontillo, Marisa
2012-11-01
Barefoot running is a trend among running enthusiasts that is the subject of much controversy. At this time, benefits appear to be more speculative and anecdotal than evidence based. Additionally, the risk of injuries is not well established. A PubMed search was undertaken for articles published in English from 1980 to 2011. Additional references were accrued from reference lists of research articles. While minimal data exist that definitively support barefoot running, there are data lending support to the argument that runners should use a forefoot strike pattern in lieu of a heel strike pattern to reduce ground reaction forces, ground contact time, and step length. Whether there is a positive or negative effect on injury has yet to be determined. Unquestionably, more research is needed before definitive conclusions can be drawn.
Callosal involvement in a lateralized stroop task in alcoholic and healthy subjects.
Schulte, T; Müller-Oehring, E M; Salo, R; Pfefferbaum, A; Sullivan, E V
2006-11-01
To investigate the role of interhemispheric attentional processes, 25 alcoholic and 28 control subjects were tested with a Stroop match-to-sample task and callosal areas were measured with magnetic resonance imaging. Stroop color-word stimuli were presented to the left or right visual field (VF) and were preceded by a color cue that did or did not match the word's color. For matching colors, both groups showed a right VF advantage; for nonmatching colors, controls showed a left VF advantage, whereas alcoholic subjects showed no VF advantage. For nonmatch trials, VF advantage correlated with callosal splenium area in controls but not alcoholic subjects, supporting the position that information presented to the nonpreferred hemisphere is transmitted via the splenium to the hemisphere specialized for efficient processing. The authors speculate that alcoholism-associated callosal thinning disrupts this processing route.

Local government should be regarded as the main subject to be stipulated by environmental law, thus to avoid local government’s alignment with commercial interests. Such a shift would, furthermore, discourage collusion against environment law or speculative behaviors motivated by maximizing production at the expense of environment pollution. Moreover, whether companies make proactive decisions to prevent pollution or not depends on the severity of appropriate environment legal system’s sanctions for their action. It would encourage enterprises to undertake their own environmental responsibility if environmental law could further enhance their environmental liability. In addition, public environmental rights should be embedded into environmental law. In this way, the public may become more aware of their environmental rights as well as the positivity of total environmental interests.
Generation of neutral and high-density electron–positron pair plasmas in the laboratory

Electron–positron pair plasmas represent a unique state of matter, whereby there exists an intrinsic and complete symmetry between negatively charged (matter) and positively charged (antimatter) particles. These plasmas play a fundamental role in the dynamics of ultra-massive astrophysical objects and are believed to be associated with the emission of ultra-bright gamma-ray bursts. Despite extensive theoretical modelling, our knowledge of this state of matter is still speculative, owing to the extreme difficulty in recreating neutral matter–antimatter plasmas in the laboratory. Here we show that, by using a compact laser-driven setup, ion-free electron–positron plasmas with unique characteristics can be produced. Their charge neutrality (same amount of matter and antimatter), high-density and small divergence finally open up the possibility of studying electron–positron plasmas in controlled laboratory experiments.

National Athletic Trainers' Association Position Statement: Prevention of Pediatric Overuse Injuries
Valovich McLeod, Tamara C.; Decoster, Laura C.; Loud, Keith J.; Micheli, Lyle J.; Parker, J. Terry; Sandrey, Michelle A.; White, Christopher
2011-01-01
Abstract Objective: To provide certified athletic trainers, physicians, and other health care professionals with recommendations on best practices for the prevention of overuse sports injuries in pediatric athletes (aged 6–18 years). Background: Participation in sports by the pediatric population has grown tremendously over the years. Although the health benefits of participation in competitive and recreational athletic events are numerous, one adverse consequence is sport-related injury. Overuse or repetitive trauma injuries represent approximately 50% of all pediatric sport-related injuries. It is speculated that more than half of these injuries may be preventable with simple approaches. Recommendations: Recommendations are provided based on current evidence regarding pediatric injury surveillance, identification of risk factors for injury, preparticipation physical examinations, proper supervision and education (coaching and medical), sport alterations, training and conditioning programs, and delayed specialization.

Recently Timberlake, Wyman, Skavenski, and Steinman (1972) concluded in a study of the oculomotor error signal in the fovea that 'the oculomotor dead zone is surely smaller than 10 min and may even be less than 5 min (smaller than the 0.25 to 0.5 deg dead zone reported by Rashbass (1961) with similar stimulus conditions).' The Timberlake et al. speculation is confirmed by demonstrating that the fixating eye consistently and accurately corrects target displacements as small as 3.4 min. The contact lens optical lever technique was used to study the manner in which the oculomotor system responds to small step displacements of the fixation target. Subjects did, without prior practice, use saccades to correct step displacements of the fixation target just as they correct small position errors during maintained fixation.

Individuals have a need to maintain positive social interactions, and with the advent of new-media technologies, there are a myriad ways individuals can satisfy this need by engaging socially in mediated (non-face-to-face) communication, hence the need for a special issue on "Relationships in the Digital Age." The articles in this special issue reflect the need to answer theoretical questions brought forth by the increased tendency for individuals to create and maintain interpersonal relationships through mediated forms of communication. The commentary highlights the need for increased research on mediated interpersonal relationships by psychologists and discusses how the articles in the issue can be used to answer theoretical questions about mediated interpersonal communication. The article ends with speculation on how media may create social spaces that may be advantageous for some individuals.

Are we a gift shop? A perspective on grade inflation.
Shoemaker, J K; DeVos, M
1999-12-01
Grade inflation is a phenomenon that has been written about extensively since the mid 1970s. It is theorized that it made its initial appearance as an adjustment to the rigorous educational standards that were imposed in the post-Sputnik era. Some authors speculate that grade inflation as we know it is an outcome of student demands for high grades combined with faculty willingness to capitulate to them. Others believe the problem is related to lack of faculty knowledge about evaluation methods, or the quest for positive student evaluations in support of promotion, tenure, and merit decisions. Of particular concern is the lack of published studies of grade inflation in nursing education. The purpose of this article is to describe what we know about grade inflation-its history, causative factors, and implications for nursing.
AIS Investigation of Agricultural Monocultures

Airborne Imaging Spectrometer (AIS) data were acquired over an agricultural area in eastern San Joaquin County, California in July, 1984. Cover type information was subsequently collected for all fields along this flight line. The lack of detailed ground data on individual fields, however, limited AIS data analysis to a qualitative comparison of the spectral reflectance curves for a total of nine cover types. Based on this analysis, it appears that cover types with a positive slope in the 1550 to 1700 nm region have a higher spectral response in the 1200 to 1300 nm region compared to those cover types with a negative slope in the 1550 to 1700 nm region. Within cover type, spectral variability was also found to be greater than that between cover types. Given the lack of additional field data, the reason for these differences is a matter of speculation.

luxR genes encode transcriptional regulators that control acyl homoserine lactone-based quorum sensing (AHL QS) in Gram negative bacteria. On the bacterial chromosome, luxR genes are usually found next or near to a luxI gene encoding the AHL signal synthase. Recently, a number of luxR genes were described that have no luxI genes in their vicinity on the chromosome. These so-called solo luxR genes may either respond to internal AHL signals produced by a non-adjacent luxI in the chromosome, or can respond to exogenous signals. Here we present a survey of solo luxR genes found in complete and draft bacterial genomes in the NCBI databases using HMMs. We found that 2698 of the 3550 luxR genes found are solos, which is an unexpectedly high number even if some of the hits may be false positives. We also found that solo LuxR sequences form distinct clusters that are different from the clusters of LuxR sequences that are part of the known luxR-luxI topological arrangements. We also found a number of cases that we termed twin luxR topologies, in which two adjacent luxR genes were in tandem or divergent orientation. Many of the luxR solo clusters were devoid of the sequence motifs characteristic of AHL binding LuxR proteins so there is room to speculate that the solos may be involved in sensing hitherto unknown signals. It was noted that only some of the LuxR clades are rich in conserved cysteine residues. Molecular modeling suggests that some of the cysteines may be involved in disulfide formation, which makes us speculate that some LuxR proteins, including some of the solos may be involved in redox regulation.

Possible climates on terrestrial exoplanets.
Forget, F; Leconte, J
2014-04-28
What kind of environment may exist on terrestrial planets around other stars? In spite of the lack of direct observations, it may not be premature to speculate on exoplanetary climates, for instance, to optimize future telescopic observations or to assess the probability of habitable worlds. To begin with, climate primarily depends on (i) the atmospheric composition and the volatile inventory; (ii) the incident stellar flux; and (iii) the tidal evolution of the planetary spin, which can notably lock a planet with a permanent night side. The atmospheric composition and mass depends on complex processes, which are difficult to model: origins of volatiles, atmospheric escape, geochemistry, photochemistry, etc. We discuss physical constraints, which can help us to speculate on the possible type of atmosphere, depending on the planet size, its final distance for its star and the star type. Assuming that the atmosphere is known, the possible climates can be explored using global climate models analogous to the ones developed to simulate the Earth as well as the other telluric atmospheres in the solar system. Our experience with Mars, Titan and Venus suggests that realistic climate simulators can be developed by combining components, such as a 'dynamical core', a radiative transfer solver, a parametrization of subgrid-scale turbulence and convection, a thermal ground model and a volatile phase change code. On this basis, we can aspire to build reliable climate predictors for exoplanets. However, whatever the accuracy of the models, predicting the actual climate regime on a specific planet will remain challenging because climate systems are affected by strong positive feedbacks. They can drive planets with very similar forcing and volatile inventory to completely different states. For instance, the coupling among temperature, volatile phase changes and radiative properties results in instabilities, such as runaway glaciations and runaway greenhouse effect.
Low Elevation Riparian Environments: Warm-Climate Refugia for Conifers in the Great Basin, USA?
NASA Astrophysics Data System (ADS)
Millar, C.; Charlet, D. A.; Westfall, R. D.; Delany, D.
2015-12-01
The Great Basin, USA, contains hundreds of small to large mountain ranges. Many reach alpine elevations, which are separated from each other by low-elevation basins currently inhospitable to conifer growth. Many of these ranges support montane and subalpine conifer species that have affinities to the Sierra Nevada or Rocky Mountains, and from which these conifers migrated during cool periods of the Pleistocene. Under Holocene climates, the Great Basin geography became a terrestrial island-archipelago, wherein conifer populations are isolated among ranges, and inter-range migration is highly limited. During warm intervals of the Holocene, conifers would be expected to have migrated upslope following favorable conditions, and extirpation would be assumed to result from continued warming. Independent patterns, repeating across multiple species' distributions, however, suggest that refugia were present in these ranges during warm periods, and that low elevation environments below the current main distributions acted as climatic refugia. We hypothesize that cool, narrow, and north-aspect ravines, which during cool climates support persistent or seasonal creeks and deciduous riparian communities, become available as conifer habitat when warming climates desiccate creeks and deplete riparian species. We further speculate that cold-air drainage, reduced solar insolation, lower wind exposure, and higher water tables in these topographic positions support populations of montane and subalpine conifers even during warm climate intervals when high elevations are unfavorable for conifer persistence. On return to cool climates, low elevation refugia become sources for recolonizing higher slopes, and/or continue to persist as relictual populations. We present several lines of evidence supporting this hypothesis, and speculate that low-elevation, extramarginal riparian environments might act as climate refugia for Great Basin conifers in the future as well.

5-HT and noradrenaline are important neurotransmitters that control increase in body mass and are involved in the pathophysiology of obesity and depression. Sibutramine, an established anti-obesity agent, and duloxetine, an anti-depressant agent, are serotonin noradrenaline reuptake inhibitors (SNRIs). The objective of the present study was to compare the anti-obesity effect of duloxetine with sibutramine along with its effect on blood pressure and depression in obese rats. The secondary objective of the study was to determine if a relationship exists between obesity and depression. Obesity was induced by high-fat diet (HFD) in healthy male Sprague-Dawley rats. After 5 weeks of feeding HFD, animals were overweight (17.57%) with high food intake (57.15%) in comparison with normal animals. These obese animals were treated with duloxetine (30 mg x kg(-1), p.o.) and sibutramine (5 mg x kg(-1), p.o.) for 4 weeks. Control animals were treated with duloxetine alone (30 mg x kg(-1), p.o.). Our results depict that duloxetine was as effective as sibutramine in reducing food intake, body mass, and relative adiposity, and increasing rectal temperature with an added advantage of decreasing blood pressure, which sibutramine failed to do. Besides reduction in body mass, unlike sibutramine, duloxetine improved depressive state as evaluated by despair swimming test, tail suspension test, and open field test, speculating its use as an anti-obesity agent in obese-depressive animals. Since obese control animals reflected decreased locomotor activity, a positive relationship can be speculated to exist between obesity and depression. Further studies on various antidepressant models are required to confirm this relationship.
Apparent increase in coccolithophore abundance in the subtropical North Atlantic from 1990 to 2014

As environmental conditions evolve with rapidly increasing atmospheric CO2, biological communities will change as species reorient their distributions, adapt, or alter their abundance. In the surface ocean, dissolved inorganic carbon (DIC) has been increasing over the past several decades as anthropogenic CO2 dissolves into seawater, causing acidification (decreases in pH and carbonate ion concentration). Calcifying phytoplankton, such as coccolithophores, are thought to be especially vulnerable to ocean acidification. How coccolithophores will respond to increasing carbon input has been a subject of much speculation and inspired numerous laboratory and mesocosm experiments, but how they are currently responding in situ is less well documented. In this study, we use coccolithophore (haptophyte) pigment data collected at the Bermuda Atlantic Time-series Study (BATS) site together with satellite estimates (1998-2014) of surface chlorophyll and particulate inorganic carbon (PIC) as a proxy for coccolithophore abundance to show that coccolithophore populations in the North Atlantic subtropical gyre have been increasing significantly over the past 2 decades. Over 1990-2012, we observe a 37 % increase in euphotic zone-integrated coccolithophore pigment abundance at BATS, though we note that this is sensitive to the period being analyzed. We further demonstrate that variability in coccolithophore chlorophyll a here is positively correlated with variability in nitrate and DIC (and especially the bicarbonate ion) in the upper 30 m of the water column. Previous studies have suggested that coccolithophore photosynthesis may benefit from increasing CO2, but calcification may eventually be hindered by low pHT (< 7.7). Given that DIC has been increasing at BATS by ˜ 1.4 µmol kg-1 yr-1 over the period of 1991-2012, we speculate that coccolithophore photosynthesis and perhaps calcification may have increased in response to anthropogenic CO2 input.

Higher prices, higher quality? Evidence from German nursing homes.
Herr, Annika; Hottenrott, Hanna
2016-02-01
This study investigates the relationship between prices and quality of 7400 German nursing homes. We use a cross section of public quality reports for all German nursing homes, which had been evaluated between 2010 and 2013 by external institutions. Our analysis is based on multivariate regressions in a two stage least squares framework, where we instrument prices to explain their effect on quality controlling for income, nursing home density, demographics, labour market characteristics, and infrastructure at the regional level. Descriptive analysis shows that prices and quality do not only vary across nursing homes, but also across counties and federal states and that quality and prices correlate positively. Second, the econometric analysis, which accounts for the endogenous relation between negotiated price and reported quality, shows that quality indeed positively depends on prices. In addition, more places in nursing homes per people in need are correlated with both lower prices and higher quality. Finally, unobserved factors at the federal state level capture some of the variation of reported quality across nursing homes. Our results suggest that higher prices increase quality. Furthermore, since reported quality and prices vary substantially across federal states, we conclude that the quality and prices of long-term care facilities may well be compared within federal states but not across.

The U.S. Federal Radionavigation Plan
NASA Astrophysics Data System (ADS)
Shirer, Heywood O.
The author presents an overview of the 1990 Federal Radionavigation Plan (FRP) policy and a discussion of the status of GPS (Global Positioning System), Loran-C, Omega, VOR/DME (VHF omnidirectional range/distance measuring equipment), VORTAC, TACAN, MLS (Microwave Landing System), ILS (instrument landing systems), Transit, and radiobeacons. The 1990 FRP contains significant changes regarding several of the radionavigation systems. It is concluded that it is difficult at best to ascertain the post-GPS final systems mix of federally provided radionavigation systems. The phase-out dates of other systems in favor of GPS still remain soft. Many uncertainties remain until the capabilities of GPS are verified for all classes of users. The federal radionavigation planning process accommodates such uncertainties, keeping pace with the constantly changing radionavigation user profile and rapid advancements in system technology.
How Will We React to the Discovery of Extraterrestrial Life?

How will humanity react to the discovery of extraterrestrial life? Speculation on this topic abounds, but empirical research is practically non-existent. We report the results of three empirical studies assessing psychological reactions to the discovery of extraterrestrial life using the Linguistic Inquiry and Word Count (LIWC) text analysis software. We examined language use in media coverage of past discovery announcements of this nature, with a focus on extraterrestrial microbial life (Pilot Study). A large online sample ( N = 501) was asked to write about their own and humanity's reaction to a hypothetical announcement of such a discovery (Study 1), and an independent, large online sample ( N = 256) was asked to read and respond to a newspaper story about the claim that fossilized extraterrestrial microbial life had been found in a meteorite of Martian origin (Study 2). Across these studies, we found that reactions were significantly more positive than negative, and more reward vs. risk oriented. A mini-meta-analysis revealed large overall effect sizes (positive vs. negative affect language: g = 0.98; reward vs. risk language: g = 0.81). We also found that people's forecasts of their own reactions showed a greater positivity bias than their forecasts of humanity's reactions (Study 1), and that responses to reading an actual announcement of the discovery of extraterrestrial microbial life showed a greater positivity bias than responses to reading an actual announcement of the creation of man-made synthetic life (Study 2). Taken together, this work suggests that our reactions to a future confirmed discovery of microbial extraterrestrial life are likely to be fairly positive.

Cont-Bouchaud Percolation Model Including Tobin Tax
NASA Astrophysics Data System (ADS)
Ehrenstein, Gudrun
The Tobin tax is an often discussed method to tame speculation and get a source of income. The discussion is especially heated when the financial markets are in crisis. In this article we refer to the foreign exchange markets. The Tobin tax should be a small international tax affecting all currency transactions and thus consequently reducing destabilizing speculations. In this way this tax should take over a control function. By including the Tobin tax in the microscopic model of Cont and Bouchaud one finds that this tax could be the right method to control foreign exchange operations and to get a good source of income.
Francis Bacon and the classification of natural history.
Anstey, Peter
2012-01-01
This paper analyses the place of natural history within Bacon's divisions of the sciences in The Advancement of Learning (1605) and the later De dignitate et augmentis scientiarum (1623). It is shown that at various points in Bacon's divisions, natural history converges or overlaps with natural philosophy, and that, for Bacon, natural history and natural philosophy are not discrete disciplines. Furthermore, it is argued that Bacon's distinction between operative and speculative natural philosophy and the place of natural history within this distinction, are discontinuous with the later distinction between experimental and speculative philosophy that emerged in the methodology of the Fellows of the early Royal Society.

The Kiyotaki and Wright (1989) (henceforth KW) model of money emergence as a medium of exchange has been studied from various perspectives in recent papers. In the present work we propose a minimalistic model for the behavior of agents in the KW framework, which may either reproduce the theoretical predictions of Kiyotaki and Wright (1989) on the emerging Nash equilibria, or (less closely) the empirical results of Brown (1996), Duffy and Ochs (1999) and our own, introduced in a first part of the present paper. The main import is the systematic computer scanning of speculative monetary equilibria under drastic bounded rationality of agents, based on behavior previously observed in the lab.

One of the lasting legacies of the financial crisis of 2008, and the legislative energies that followed from it, is the growing reliance on econometrics as part of the rulemaking process. Financial regulators are increasingly expected to rationalize proposed rules using available econometric techniques, and the courts have vacated several key rules emanating from Dodd-Frank on the grounds of alleged deficiencies in this evidentiary effort. The turn toward such econometric tools is seen as a significant constraint on and challenge to regulators as they endeavor to engage with such essential policy questions as the impact of financial speculation on food security. Yet, outside of the specialized practitioner community, very little is known about these techniques. This article examines one such econometric test, Granger causality, and its role in a pivotal Dodd-Frank rulemaking. Through an examination of the test for Granger causality and its attempts to distill the causal connections between financial speculation and commodities prices, the article argues that econometrics is a blunt but useful tool, limited in its ability to provide decisive insights into commodities markets and yet yielding useful returns for those who are able to wield it.
Structural analysis of NADPH depleted bovine liver catalase and its inhibitor complexes
Sugadev, Ragumani; Ponnuswamy, M.N.; Sekar, K.
2011-01-01
To study the functional role of NADPH during mammalian catalase inhibition, the X-ray crystal structures of NADPH-depleted bovine liver catalase and its inhibitor complexes, cyanide and azide, determined at 2.8Å resolution. From the complex structures it is observed that subunits with and without an inhibitor/catalytic water molecule are linked by N-terminal domain swapping. Comparing mammalian- and fungal- catalases, we speculate that NADPH-depleted mammalian catalases may function as a domain-swapped dimer of dimers, especially during inactivation by inhibitors like cyanide and azide. We further speculate that in mammalian catalases the N-terminal hinge-loop region and α-helix is the structural element that senses NADPH binding. Although the above arguments are speculative and need further verification, as a whole our studies have opened up a new possibility, viz. that mammalian catalase acts as a domain-swapped dimer of dimers, especially during inhibitor binding. To generalize this concept to the formation of the inactive state in mammalian catalases in the absence of tightly bound NADPH molecules needs further exploration. The present study adds one more intriguing fact to the existing mysteries of mammalian catalases. PMID:21968615
A speculated cause of respiratory inhibition in infants.
Minowa, Hideki; Arai, Ikuyo; Yasuhara, Hajime; Ebisu, Reiko; Ohgitani, Ayako
2018-10-01
In our previous studies, we documented that threatened premature labor and asymmetrical intrauterine growth restriction were risk factors for respiratory inhibition. The goal of this study was to determine the cause of respiratory inhibition by considering perinatal risk factors. We examined 1497 infants with a gestational age of 36 weeks or greater. All infants were monitored using pulse oximetry and examined via cranial sonography. Respiratory inhibition was defined as severe hypoxemia caused by respiratory inhibition immediately after crying or gastroesophageal reflux or as a respiratory pause during feeding. We examined the relationships between respiratory inhibition and perinatal factors and speculated on the cause of respiratory inhibition. The median gestational age, birth weight, Apgar score at 1 min, and Apgar score at 5 min of the subjects were 38.9 weeks, 2930 g, 8.0 points, and 9.0 points, respectively. Respiratory inhibition was observed in 422 infants. Lateral ventricle enlargement and increased echogenicity in the ganglionic eminence were observed in 417 and 516 infants, respectively. Respiratory inhibition was significantly correlated with shorter gestational periods, twin pregnancies, lateral ventricle enlargement, and increased echogenicity in the ganglionic eminence. We speculate that umbilical cord compression is a major cause of respiratory inhibition.

Altered states: state health privacy laws and the impact of the Federal Health Privacy Rule.
Pritts, Joy L
2002-01-01
Although the Federal Health Privacy Rule has evened out some of the inconsistencies between states' health privacy laws, gaps in protection still remain. Furthermore, the Federal Rule contains some lax standards for the disclosure of health information. State laws can play a vital role in filling these gaps and strengthening the protections afforded health information. By enacting legislation that has higher privacy-protective standards than the Federal Health Privacy Rule, states can play three important roles. First, because they can directly regulate entities that are beyond HHS's mandate, states can afford their citizens a broader degree of privacy protection than the Federal Health Privacy Rule. Second, by having state health privacy laws, states can enforce privacy protections at the local level. Finally, action by the states can positively influence health privacy policies at the federal level by raising the standard as to what constitutes sufficient privacy protection. High privacy protections imposed by states may serve as the standard for comprehensive federal legislation, if and when Congress reconsiders the issue. So far, states' reactions to the Federal Privacy Rule have been mixed. Only time will tell whether states will assume the mantle of leadership on health privacy or relinquish their role as the primary protectors of health information.

Ethnic Enclaves and the Earnings of Immigrants
Xie, Yu; Gough, Margaret
2011-01-01
A large literature in sociology concerns the implications of immigrants’ participation in ethnic enclaves for their economic and social well-being. The “enclave thesis” speculates that immigrants benefit from working in ethnic enclaves. Previous research concerning the effects of enclave participation on immigrants’ economic outcomes has come to mixed conclusions as to whether enclave effects are positive or negative. In this article, we seek to extend and improve upon past work by formulating testable hypotheses based on the enclave thesis and testing them with data from the 2003 New Immigrant Survey (NIS), employing both residence-based and workplace-based measures of the ethnic enclave. We compare the economic outcomes of immigrants working in ethnic enclaves with those of immigrants working in the mainstream economy. Our research yields minimal support for the enclave thesis. Our results further indicate that for some immigrant groups, ethnic enclave participation actually has a negative effect on economic outcomes. PMID:21863367

This study compared message-framing effects on physical activity (PA) across age and gender groups. Participants included 111 younger and 100 older adults (68% were women), randomly assigned to read gain-framed or loss-framed PA messages in promotion pamphlets, and who wore accelerometers for the following 14 days. Using regression analyses controlling for demographic and health factors, we found significant age-by-gender-by-framing interactions predicting self-report (B = -4.39, p = .01) and accelerometer-assessed PA (B = -2.44, p = .02) during the follow-up period. Gain-framed messages were more effective than loss-framed messages in promoting PA behaviors only among older men. We speculated that the age-related positivity effect, as well as the age and gender differences in issue involvement, explained the group differences in framing. In addition, more time availability and higher self-efficacy among older men might have contributed to the results.

We report a 5.9-year-old boy with X-linked lymphoproliferative syndrome (XLP) who presented with acute severe infectious mononucleosis. Clinical symptoms rapidly improved after chemotherapy with etoposide. Allogeneic bone marrow transplantation (BMT) was performed after conditioning with etoposide, busulfan and cyclophosphamide. After successful hematopoietic recovery we were able to demonstrate seroconversion from an impaired antibody response to Epstein-Barr virus (EBV) to a normal antibody-producing state in an immunocompetent child. The only post-transplant complication was mild acute graft-versus-host disease (GVHD). Three years after BMT, the boy is healthy and shows no signs of immunodeficiency. This is the first report on successful allogeneic BMT in the severe course of acute infectious mononucleosis in a patient with XLP. We speculate that the application of etoposide contributed to the positive outcome in this patient.
Primary lymphoma of the central nervous system and HTLV-I infection.
Calderón, Enrique J; Japón, Miguel A; Chinchón, Isidoro; Soriano, Vicente; Capote, Francisco J
2002-01-01
Only a few cases of AIDS-related primary lymphomas of the central nervous system (CNS) show a T-cell phenotype. We have recently studied two intravenous drug users with HIV infection who had primary CNS T-cell lymphomas. In both cases, the enzyme immunoassay (EIA) for HTLV gave a positive result. In the first case, study by western-blot (WB) and specific PCR confirmed the human T-cell lymphotropic virus type I (HTLV-I) infection and serological study by EIA for HTLV of his mother was negative. In the second case, analysis of ante-mortem serum samples by two different WBs showed an indeterminate pattern suggestive of HTLV-I infection, but adequate samples for PCR were not available. We speculate about the possibility that the horizontal transmission of HTLV-I infection could have facilitated the devepolment of a primary CNS T-cell lymphoma in these HIV patients, although they cannot be strictly considered as ATLL cases.
Hypereosinophilia and seroconversion of rheumatoid arthritis.
Rosenstein, Rachel K; Panush, Richard S; Kramer, Neil; Rosenstein, Elliot D
2014-11-01
At the intersection of atopy and autoimmunity, we present a patient with seronegative rheumatoid arthritis (RA) who developed hypereosinophilia, without evidence of other etiologies, as she became rheumatoid factor (RF) positive. Although the magnitude of eosinophilia in patients with RA has been thought to reflect the severity or activity of the RA, in our patient, eosinophilia developed at a time when the patient's synovitis was well controlled. Although eosinophilia may reflect associated drug hypersensitivity, discontinuation of the medications utilized to control our patient's disease, adalimumab and methotrexate, did not promote clinical improvement. Probably the most curious aspect of our patient was the concomitant development of rheumatoid factor seropositivity in the setting of previously seronegative RA. The temporal relationship between the development of peripheral eosinophilia and seroconversion suggests a possible connection between these events. We speculate that the T cell cytokine production that can induce eosinophilia may simultaneously activate RF production.

The principles of anatomy and physiology necessary for understanding brain wave recordings made from the scalp of normal people are briefly discussed. Brain waves evoked by sounds are described and certain of their features are related to the physical aspects of the stimulus and to the psychological state of the listener. The position is taken that data obtained through scalp probes can reveal a large amount of detail about brain functioning and that analysis of such records enable detection of the response of the nervous system to an acoustic message at the moment of its inception and to the progress of the message through the brain. Brain events responsible for distinguishing between similar signals and making decisions about them appear to generate characteristic and identifiable electrical waves. Some theoretical speculation about these data are introduced with the aim of generating a more heuristic model of the functioning brain.

We performed a cross-sectional study of all Thames maternity units, 1994-96, including 540,834 live and stillbirths. In contrast to recent media speculation, no association of caesarean section rates with midwifery staffing levels was found after adjustment for confounders. The only association with staffing was with levels of junior obstetric staffing, which could be a reflection of less experienced management of labour. Caesarean section rates were also associated positively with the levels of delivery beds, which could be a reflection of the closer monitoring of labour that may result from increased bed availability. Both caesarean section and instrumental vaginal delivery rates were associated with epidural rates, which was expected from the literature. Variations in epidural rates were mainly associated with variations in demographic case-mix, due possibly to patient demand. Demographic case-mix was also associated with instrumental vaginal deliveries but not the caesarean section rate.
BCG-induced pneumonitis with lymphocytic pleurisy in the absence of elevated KL-6
2014-01-01
Background Pneumonitis is a rare complication of bacillus Calmette-Guerin (BCG) immunotherapy seen in patients with urothelial cancer following the repeated administration of BCG. However, no case of BCG-induced pleurisy has been reported. Case presentation We here report the first case of pneumonitis with lymphocytic pleurisy following bacillus Calmette-Guerin (BCG) immunotherapy. Although marked T helper cell alveolitis was found by bronchoalveolar lavage and transbronchial biopsies, no acid-fast bacillus could be identified in recovered BALF or pleural effusion. The lymphocyte stimulation test of BCG was strongly positive. However, levels of serum and bronchoalveolar lavage fluid KL-6, a useful marker for hypersensitivity pneumonitis (HP), were within normal ranges. Conclusion We speculate that the pathogenesis of our case may be a hypersensitive reaction to the proteic component of BCG entering the lung and pleural space, which is different from the etiology of the common type of HP.

Range : 241,000km (150,600 mi.). This black and white image of Europa, smallest of Jupiter's four Galilean satellites, was acquired by Voyager 2. Europa, the brightest of the Galiliean satellites, has a density slightly less than Io, suggesting it has a substantial quantity of water. Scientists previously speculated that the water must have cooled from the interior and formed a mantle of ice perhaps 100 km thick. The complex patterns on its surface suggest that the icy surface was fractured, and that the cracks filled with dark material from below. Very few impact craters are visible on the surface, suggesting that active processes on the surface are still modifying Europa. The tectonic pattern seen on its surface differs drastically from the fault systems seen on Ganymede where pieces of the crust have moved relative to each other. On Europa, the crust evidently fractures but the pieces remain in roughly their original position.
Is There Evidence to Support a Forefoot Strike Pattern in Barefoot Runners? A Review
Lorenz, Daniel S.; Pontillo, Marisa
2012-01-01
Context: Barefoot running is a trend among running enthusiasts that is the subject of much controversy. At this time, benefits appear to be more speculative and anecdotal than evidence based. Additionally, the risk of injuries is not well established. Evidence acquisition: A PubMed search was undertaken for articles published in English from 1980 to 2011. Additional references were accrued from reference lists of research articles. Results: While minimal data exist that definitively support barefoot running, there are data lending support to the argument that runners should use a forefoot strike pattern in lieu of a heel strike pattern to reduce ground reaction forces, ground contact time, and step length. Conclusions: Whether there is a positive or negative effect on injury has yet to be determined. Unquestionably, more research is needed before definitive conclusions can be drawn. PMID:24179586

A single free-ranging common brushtail possum (Trichosurus vulpecula) and 2 captive sibling common ringtail possums (Pseudocheirus peregrinus)from a zoological facility in Sydney, Australia, were diagnosed with multisystemic listeriosis. The brushtail was found dead in an animal enclosure while the ringtails presented with signs of cardiovascular collapse and died shortly thereafter. All 3 animals were culture positive forListeria monocytogenesand demonstrated focal suppurative lesions within the brainstem in addition to fulminant disease in other areas of the thorax and/or abdomen. Listeriosis in phalangeriformes species has rarely been reported, and brainstem lesions have not previously been described. It is speculated that access to the brainstem by the organism may have occurred hematogenously or via retrograde migration along cranial nerves. Sources of infection and the possibility of transmission between animals are also discussed. © The Author(s) 2015.
Project Ozma: The Birth of Observational SETI

Shuch, H. Paul
It was an idea whose time had come, but nobody dared admit that out loud. Frank Drake, in particular, was keeping silent. Like many of his generation, he had long speculated about the existence of extraterrestrial life, and pondered how we humans might probe for direct evidence of our cosmic companions. Now, in 1959, the young astronomer was finally in a position to do more than ponder. At 29, he had just completed graduate school, the ink on his Harvard diploma as wet as he was behind the ears. As the new kid on the block at the National Radio Astronomy Observatory, he had access to the tools necessary to mount a credible search for radio evidence of distant technological civilizations. Drake knew enough to tread lightly; a publicly announced hunt for Little Green Men would be tantamount to professional suicide, so he approached his superior with understandable trepidation.
Fibrosarcoma of the eyelid in two sibling Czech wolfdogs
Nordio, Laura; Fattori, Sabina; Giudice, Chiara
2017-01-01
Most canine tumors of the eyelid are tumors generally encountered in the skin. They are most commonly of epithelial origin and benign. In this report, we describe the cases of two sibling Czech wolfdogs presented, one year apart, with a subcutaneous mass involving the left eyelid. Both lesions were histologically consistent with a diagnosis of subcutaneous fibrosarcoma. Immunohistochemical analyses of the tumors revealed a mild positivity for vimentin and negativity for GFAP, desmin, αSMA, myoglobin, S100, PNL2 and calponin, excluding all differential diagnosis (i.e. peripheral nerve sheath tumor, melanoma, perivascular sarcoma, myofibroblastic sarcoma, rhabdomyosarcoma). To the best of authors’ knowledge, this is the first report of canine eyelid fibrosarcoma. Since this rare tumor has been observed in two full siblings, we could speculate the existence of some genetic predisposition to sarcoma, however the present data did not allow any definite conclusion on the etiopathogenesis or genetic basis of these tumors.

Boundary-layer surveys were made throughout the transition region along a smooth flat plate placed in an airstream of practically zero turbulence and with an adverse pressure gradient. The boundary-layer Reynolds number at the laminar separation point was varied from 1,800 to 2,600. The test data, when considered in the light of certain theoretical deductions, indicated that transition probably began with separation of the laminar boundary layer. The extent of the transition region, defined as the distance from a calculated laminar separation point to the position of the first fully developed turbulent boundary-layer profile, could be expressed as a constant Reynolds number run of approximately 70,000. Some speculations are presented concerning the application of the foregoing concepts, after certain assumptions have been made, to the problem of the connection between transition on the upper surface of an airfoil at high angles of attack and the maximum lift.
Big five personality and residential mobility: a state-level analysis of the USA.
McCann, Stewart J H
2015-01-01
Relations of the state-aggregated Big Five personality scores of 619,397 residents to four 2005 state-level residential mobility criteria were examined with the 50 states as cases. Multiple regression controlling for five state demographic variables showed (a) higher state neuroticism was strongly associated with lower mobility, lower same-county mobility, and lower between-county mobility; (b) higher state extraversion was associated with lower mobility and lower same-county mobility, but only with neuroticism and/or conscientiousness controlled; and (c) conscientiousness was related to same-residence, same-county, and different-county mobility, but only without demographic variables controlled. Discussion is grounded in the dangers of cross-level speculation and the potential of a basic assumption of geographical psychology that an area's aggregate position on a dispositional variable is associated there with behavioral and psychological tendencies related to that variable.
Modern Antarctic acorn worms form tubes.
Halanych, Kenneth M; Cannon, Johanna T; Mahon, Andrew R; Swalla, Billie J; Smith, Craig R
2013-01-01
Acorn worms, or enteropneusts, are vermiform hemichordates that occupy an important position in deuterostome phylogeny. Allied to pterobranch hemichordates, small colonial tube dwellers, modern enteropneusts were thought to be tubeless. However, understanding of hemichordate diversity is poor, as evidenced by absence of reports from some oceanic regions and recent descriptions of large epibenthic deep-water enteropneusts, Torquaratoridae. Here we show, based on expeditions to Antarctica, that some acorn worms produce conspicuous tubes that persist for days. Interestingly, recent fossil descriptions show a Middle Cambrian acorn worm lived in tubes, leading to speculation that these fossils may have been pterobranch forbearers. Our discovery provides the alternative interpretation that these fossils are similar to modern-day torquaratorids and that some behaviours have been conserved for over 500 million years. Moreover, the frequency of Antarctic enteropneusts observed attests to our limited knowledge of Antarctic marine ecosystems, and strengthens hypotheses relating more northern deep-sea fauna to Antarctic shelf fauna.
Modulation of UK lightning by heliospheric magnetic field polarity

Observational studies have reported solar magnetic modulation of terrestrial lightning on a range of time scales, from days to decades. The proposed mechanism is two-step: lightning rates vary with galactic cosmic ray (GCR) flux incident on Earth, either via changes in atmospheric conductivity and/or direct triggering of lightning. GCR flux is, in turn, primarily controlled by the heliospheric magnetic field (HMF) intensity. Consequently, global changes in lightning rates are expected. This study instead considers HMF polarity, which doesn't greatly affect total GCR flux. Opposing HMF polarities are, however, associated with a 40-60% difference in observed UK lightning and thunder rates. As HMF polarity skews the terrestrial magnetosphere from its nominal position, this perturbs local ionospheric potential at high latitudes and local exposure to energetic charged particles from the magnetosphere. We speculate as to the mechanism(s) by which this may, in turn, redistribute the global location and/or intensity of thunderstorm activity.
Radiation damage in high voltage silicon solar cells

Weinberg, I.; Brandhorst, H., Jr.; Swartz, C. K.; Weizer, V. G.
1980-01-01
Three high open-circuit voltage cell designs based on 0.1 ohm-cm p-type silicon were irradiated with 1 MeV electrons and their performance determined to fluences as high as 10 to the 15th power/sq cm. Of the three cell designs, radiation induced degradation was greatest in the high-low emitter (HLE cell). The diffused and ion implanted cells degraded approximately equally but less than the HLE cell. Degradation was greatest in an HLE cell exposed to X-rays before electron irradiation. The cell regions controlling both short-circuit current and open-circuit voltage degradation were defined in all three cell types. An increase in front surface recombination velocity accompanied time dependent degradation of an HLE cell after X-irradiation. It was speculated that this was indirectly due to a decrease in positive charge at the silicon-oxide interface. Modifications aimed at reducing radiation induced degradation are proposed for all three cell types.
Motility-Induced Phase Separation

Cates, Michael E.; Tailleur, Julien

Self-propelled particles include both self-phoretic synthetic colloids and various microorganisms. By continually consuming energy, they bypass the laws of equilibrium thermodynamics. These laws enforce the Boltzmann distribution in thermal equilibrium: The steady state is then independent of kinetic parameters. In contrast, self-propelled particles tend to accumulate where they move more slowly. They may also slow down at high density for either biochemical or steric reasons. This creates positive feedback, which can lead to motility-induced phase separation (MIPS) between dense and dilute fluid phases. At leading order in gradients, a mapping relates variable-speed, self-propelled particles to passive particles with attractions. This deep link to equilibrium phase separation is confirmed by simulations but generally breaks down at higher order in gradients: New effects, with no equilibrium counterpart, then emerge. We give a selective overview of the fast-developing field of MIPS, focusing on theory and simulation but including a brief speculative survey of its experimental implications.
The laugh of Satan: a study of a familial murderer.
McCully, R S
1978-02-01
A teenage murderer who killed his mother, his tiny half-brother, and his step-father was studied through the imagery he associated to three different editions of inkblots. These sets included the Rorschach, Behn-Rorschach, and Ka-Ro plates. The data were used to theorize about clues, dynamics, and diagnosis in this extreme case of adolescent violence. Family background and developmental history are included. The author takes the position that a conventional analysis of these data alone is not sufficient to fully understand familial murderers. Several of C.G. Jung's concepts, notably his view about the power of shadow-projections to influence conscious percepts and his philosophy about evil as a collective phenomenon, were used to speculate about ways we might extend our understanding of this subject's extreme form of violence. Defining the archetype as an energy-complex, the discussion theorized about possible ways different forms of paranoid ideation may arise.

This study examined the role of visual working memory when transforming visual representations to motor representations in the context of motor imagery. Participants viewed randomized number sequences of three, four, and five digits, and then reproduced the sequence by finger tapping using motor imagery or actually executing the movements; movement duration was recorded. One group viewed the stimulus for three seconds and responded immediately, while the second group had a three-second view followed by a three-second blank screen delay before responding. As expected, delay group times were longer with each condition and digit load. Whereas correlations between imagined and executed actions (temporal congruency) were significant in a positive direction for both groups, interestingly, the delay group's values were significantly stronger. That outcome prompts speculation that delay influenced the congruency between motor representation and actual execution.
Insight into hydrogenation of graphene: Effect of hydrogen plasma chemistry

Felten, A.; Nittler, L.; Pireaux, J.-J.
2014-11-03
Plasma hydrogenation of graphene has been proposed as a tool to modify the properties of graphene. However, hydrogen plasma is a complex system and controlled hydrogenation of graphene suffers from a lack of understanding of the plasma chemistry. Here, we correlate the modifications induced on monolayer graphene studied by Raman spectroscopy with the hydrogen ions energy distributions obtained by mass spectrometry. We measure the energy distribution of H{sup +}, H{sub 2}{sup +}, and H{sub 3}{sup +} ions for different plasma conditions showing that their energy strongly depends on the sample position, pressure, and plasma power and can reach values asmore » high as 45 eV. Based on these measurements, we speculate that under specific plasma parameters, protons should possess enough energy to penetrate the graphene sheet. Therefore, a graphene membrane could become, under certain conditions, transparent to both protons and electrons.« less

We examined the apparent dissociation of perceived length and perceived position with respect to the Muller-Lyer (M-L) illusion. With the traditional (two-chevron) figure, participants made accurate open-loop pointing responses at the endpoints of the shaft, despite the presence of a strong length illusion. This apparently non-Euclidean outcome replicated that of Mack, Heuer, Villardi, and Chambers (1985) and Gillam and Chambers (1985) and contradicts any theory of the M-L illusion in which mislocalization of shaft endpoints plays a role. However, when one of the chevrons was removed, a constant pointing error occurred in the predicted direction, as well as a strong length illusion. Thus, with one-chevron stimuli, perceived length and location were no longer completely dissociated. We speculated that the presence of two opposing chevrons suppresses the mislocalizing effects of a single chevron, especially for figures with relatively short shafts.
Royal ruptures: Caroline of Ansbach and the politics of illness in the 1730s.
Jones, Emrys D
2011-06-01
Caroline of Ansbach, wife of George II, occupied a crucial position in the public life of early 18th-century Britain. She was seen to exert considerable influence on the politics of the court and, as mother to the Hanoverian dynasty's next generation, she became an important emblem for the nation's political well-being. This paper examines how such emblematic significance was challenged and qualified when Caroline's body could no longer be portrayed as healthy and life giving. Using private memoirs and correspondence from the time of her death in 1737, the paper explores the metaphorical potential of the queen's strangulated hernia, as well as the particular problems it posed for the public image of her dynasty. Through these investigations, the paper will comment upon the haphazard nature of public discussion in the early 18th century, and reveal the complex relationship between political speculation and medical diagnosis.
Circumcision policy: A psychosocial perspective.
Goldman, Ronald
2004-11-01
The debate about the advisability of circumcision in English-speaking countries has typically focused on the potential health factors. The position statements of committees from national medical organizations are expected to be evidence-based; however, the contentiousness of the ongoing debate suggests that other factors are involved. Various potential factors related to psychology, sociology, religion and culture may also underlie policy decisions. These factors could affect the values and attitudes of medical committee members, the process of evaluating the medical literature and the medical literature itself. Although medical professionals highly value rationality, it can be difficult to conduct a rational and objective evaluation of an emotional and controversial topic such as circumcision. A negotiated compromise between polarized committee factions could introduce additional psychosocial factors. These possibilities are speculative, not conclusive. It is recommended that an open discussion of psychosocial factors take place and that the potential biases of committee members be recognized.

Evaluate the effect of the relationship among public health expenditures, income inequality, and the marginalization index on maternal and child mortality in Mexico, to determine the effect of these factors on health system performance from a technical efficiency perspective. An ecological study of 32 Mexican states. Correlations were estimated between maternal and infant mortality and public health expenditures in total per capita, federal per capita, and state per capita for the years 2000, 2005, and 2010 (Gini coefficient and marginalization index). Linear regressions were used to explore the association of these variables with health indicators in the state systems. Negative correlations were observed for the marginalization index and Gini coefficient with regard to life expectancy at birth (-0.62 and -0.28 respectively). Furthermore, there was a positive correlation of 0.59 between the marginalization index and infant mortality (P <0.05). Multiple linear regression models revealed a negative effect of the marginalization index and Gini coefficient on health out-comes. Federal funding had a positive effect on system performance in terms of health indicators. Health system reform in Mexico has had a positive impact on the country's health indicators; federal financial investment seems to be effective in this regard. Social determinants have an important effect on health system performance, and analysis using multisectoral and multidisciplinary approaches are needed in addressing them.

The federal system in Germany necessitates that in addition to federal laws, country and church-specific legislations must also be considered during the evaluation of relevant legal stipulations concerning data protection. Furthermore, there are also special legal regulations for hospitals in almost every federal state which are governed by the principle of subsidiarity: special legal regulations are to be preferentially used, so that findings from one federal state are difficult to transfer to another federal state.Patient data may only be used and processed without legal regulations with informed consent of the patient. The use of patient data for purposes of quality assurance, research and further education of students and doctors is possible under the present laws according to a positive weighting of interests. Patient data can also be exchanged via online services for the purposes of patient care; however, informed consent of the patient for medical online services is almost always unavoidable.

Movement of the lacrimal canalicular wall has been speculated to occur during blinking. Movement of the common internal ostium has been observed under nasal endoscopy, and pressure changes in the lacrimal canalicular cavity have been observed with a pressure sensor; however, lacrimal canalicular wall movement under pressure changes has not been observed. To examine movement of the lacrimal canalicular wall under intracanalicular pressure changes using dacryoendoscopy. The authors examined 20 obstruction-free lacrimal canaliculi in 10 patients. A dacryoendoscope was inserted, and water was poured into the intracanalicular cavity via the dacryoendoscope's water channel. The water was then poured or suctioned to cause positive or negative pressure changes in the intracanalicular cavity, and movement of the lacrimal canalicular wall was examined. The lacrimal canalicular wall moved flexibly with pressure changes. Under positive pressure, the intracanalicular cavity was dilated; however, it narrowed under negative pressure. The extent of movement was more dramatic in the common canalicular portion than the proximal canalicular portion. Intracanalicular pressure changes cause movement of the lacrimal canalicular wall. There was a consistent relationship between intracanalicular cavity changes and pressure changes, possibly contributing to lacrimal drainage of the canaliculus.

We report the first complete mitochondrial (mt) DNA sequence from a member of the phylum Chaetognatha (arrow worms). The Paraspadella gotoi mtDNA is highly unusual, missing 23 of the genes commonly found in animal mtDNAs, including atp6, which has otherwise been found universally to be present. Its 14 genes are unusually arranged into two groups, one on each strand. One group is punctuated by numerous non-coding intergenic nucleotides, while the other group is tightly packed, having no non-coding nucleotides, leading to speculation that there are two transcription units with differing modes of expression. The phylogenetic position of the Chaetognatha withinmore » the Metazoa has long been uncertain, with conflicting or equivocal results from various morphological analyses and rRNA sequence comparisons. Comparisons here of amino acid sequences from mitochondrially encoded proteins gives a single most parsimonious tree that supports a position of Chaetognatha as sister to the protostomes studied here. From this, one can more clearly interpret the patterns of evolution of various developmental features, especially regarding the embryological fate of the blastopore.« less

In order to test the hypothesis that neurosecretory axon regeneration occurs only in the presence of specific vascular, perivascular, and glial microenvironments, isografts of neural lobe and optic nerve and autografts of sciatic nerve were transplanted into the hypothalamo-neurohypophysial tract at the lateral retrochiasmatic area of adult male rats. The integrity of the blood-brain barrier (BBB) to intravenously administered horseradish peroxidase (HRP), the regenerative process of neurosecretory axons, and functional recovery from lesion-induced diabetes insipidus were analyzed at 18 hr, 36 hr, 10 days, 30 days, and 80 days postsurgery. Neurophysin-positive axons invaded all grafts, as well as perivascular spaces of the adjacent hypothalamus. Wherever neurosecretory axon regeneration occurred, the BBB was breached. Reestablishment of the BBB was paralleled by a decrease in both density and staining intensity of regenerated neurophysin-positive axons. These observations illustrate that neurosecretory axon regeneration is tributary of the absence of BBB. It is speculated that blood-borne factors, provided when the BBB is breached, initiate and sustain neurosecretory axon regeneration. In addition, products of glial elements may enhance or complement the above stimulatory processes.

Toxocarosis involving cranial nerves is extremely rare and almost exclusively concerns the optic nerve. Toxocarosis involving the seventh cranial nerve has not been reported. A 33y male developed left-sided Bell's palsy two days after left-sided otalgia 6y before. Despite extensive diagnostic work-up at that time the cause of Bell's palsy remained unknown. During the following years Bell's palsy slightly improved but retromandibular pain remained almost unchanged and he developed enlarged lymph nodes along the jugular veins, submandibularly, and in the trigonum caroticum. Re-evaluation 6y later revealed an increased titer of serum antibodies against Toxocara canis and a positive Westernblot for Toxocara canis ES-antigen. Despite absent eosinophilia in the serum, toxocarosis was diagnosed and a therapy with albendazole initiated, with benefit for retromandibular pain, but hardly for Bell's palsy or enlarged lymph nodes. CSF investigations after albendazole revealed a positive Westernblot for antibodies against toxocara but absent pleocytosis or eosinophilia, and negative PCR for Toxocara canis. Visceral larva migrans due to Toxocara canis may be associated with Bell's palsy, retromandibular pain, and lymphadenopathy. A causal relation between Bell's palsy and the helminthosis remains speculative. Adequate therapy years after onset of the infestation may be of limited benefit.

In "The Reunion Process: A New Focus in Short-Term Dynamic Psychotherapy," by Dr. Sandler (see record 2007-09422-001), addresses posttreatment relapse by a new therapeutic strategy based on attachment theory and recent research findings concerning the neurobiology of memory. This strategy involves the discovery or creation of positive childhood maternal attachment memories as a method of overcoming the dominance of negative memories. Dr. Sandler makes assumptions about what can be achieved in short-term therapies, the pace of therapeutic change, as well as the role in treatment outcome of techniques versus therapist skill and relationship factors. These assumptions are not supported by psychotherapy research. While the attempt to use new discoveries from neurobiology to guide the development of therapeutic techniques is admirable, the author appears to engage in a fair amount of speculative theoretical reductionism in attempting to explain the eventually positive outcome of the case he presents. I offer a more parsimonious psychological explanation, which is consistent with the short-term dynamic psychotherapy theory of change. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

To elucidate the molecular mechanism of familial central diabetes insipidus (FDI), we sequenced the arginine vasopressin-neurophysin II (AVP-NPII) gene in 2 patients belonging to a pedigree that is consistent with an autosomal dominant mode of inheritance. 10 patients with idiopathic central diabetes insipidus (IDI) and 5 normals were also studied. The AVP-NPII gene, locating on chromosome 20, consists of three exons that encode putative signal peptide, AVP, NPII, and glycoprotein. Using polymerase chain reaction, fragments including the promoter region and all coding regions were amplified from genomic DNA and subjected to direct sequencing. Sequences of 10 patients with IDI were identical with those of normals, while in 2 patients with FDI, a single base substitution was detected in one of two alleles of the AVP-NPII gene, indicating they were heterozygotes for this mutation. It was a G----A transition at nucleotide position 1859 in the second exon, resulting in a substitution of Gly for Ser at amino acid position 57 in the NPII moiety. It was speculated that the mutated AVP-NPII precursor or the mutated NPII molecule, through their conformational changes, might be responsible for AVP deficiency. Images PMID:1840604
On the dynamics of exotic matter: Towards creation of Perpetuum Mobile of third kind

The one-dimensional dynamics of a classical ideal ‘exotic’ fluid with equation of state p=p(γ)<0 violating the weak energy condition is discussed. Under certain assumptions it is shown that the well-known Hwa-Bjorken exact solution of one-dimensional relativistic hydrodynamics is confined within the future/past light cone. It is also demonstrated that the total energy of such a solution is equal to zero and that there are regions within the light cone with negative (-) and positive (+) total energies. For certain equations of state there is a continuous energy transfer from the (-)-regions to the (+)-regions resulting in indefinite growth of energy in the (+)-regions with time, which may be interpreted as action of a specific ‘Perpetuum Mobile’ (Perpetuum Motion). It is speculated that if it is possible to construct a three-dimensional non-stationary flow of an exotic fluid having a finite negative value of energy such a situation would also occur. Such a flow may continuously transfer positive energy to gravitational waves, resulting in a runaway. It is conjectured that theories plagued by such solutions should be discarded as inherently unstable.

Study objectives were to measure awareness of general antitobacco messages in LGBT-focused and general media outlets among LGBT (lesbian, gay, bisexual, and transgender) individuals and to examine associations between sociodemographic characteristics and awareness levels. Data were based on cross-sectional survey data from a racially diverse sample of participants (N = 726). Participants were primarily male (69.3%), with smaller percentages of female (21.8%) and transgender (8.9%). The median age was 31 years. A higher proportion of participants reported awareness of antitobacco messages in general media outlets compared to LGBT-specific media outlets. Awareness of antitobacco messages in general media was positively associated with current smoking and negatively associated with female gender and Latino ethnicity. Awareness of antitobacco messages in LGBT media was positively associated with younger age, current smoking, frequent reading of LGBT newspapers or magazines, and frequent attendance at LGBT bars and negatively associated with Latino ethnicity. Despite frequent readership, awareness of antitobacco messages in LGBT newspapers/magazines was quite low. We speculate that low awareness is related to the absence of antitobacco messages in LGBT-related media. LGBT-specific media outlets provide an important opportunity for future antitobacco campaigns. © 2014 Society for Public Health Education.
EEOC sues employer who demanded janitor take HIV test. Equal Employment Opportunity Commission.
1995-07-28
The Equal Employment Opportunity Commission (EEOC) has filed suit on behalf of a former janitor whose employer, [name removed] and Associations, insisted he take an HIV-antibody test and spread rumors that he was HIV-positive. The janitor (known as John Doe) had worked at the Third East Hills Park Cooperative, a low-income housing complex in Pittsburgh, for three years. His employer began speculating about his HIV status when Doe's wife died of AIDS-related complications. The manager of the apartment complex began investigating Doe and asked him to be tested for HIV antibodies. The manager went so far as to call Doe's babysitter to tell her that he thought both Doe and his son were HIV-positive and that she should leave as soon as possible. The lawsuit alleges that [name removed] and Association and Third East Hills Park Cooperative violated Title I of the Americans with Disabilities Act (ADA), which protects employees from intrusive medical questions that are unrelated to job performance. The suit seeks compensatory and punitive damages, and an injunction barring the defendants from engaging in unlawful medical inquiries and harassing workers based on disability.

Bacterial remnants and subclinical biofilms residing on prosthesis surfaces have been speculated to play a role in hip implant loosening by opsonizing otherwise relatively inert wear particles. The innate immune system recognizes these microbial pathogen-associated molecular patterns (PAMPs) using Toll-like receptors (TLRs). Our objective was to evaluate the possible presence of TLRs in aseptic synovial membrane-like interface tissue. Bacterial culture-negative, aseptic (n = 4) periprosthetic synovial membrane-like tissue was compared to osteoarthritis synovial membrane (n = 5) for the presence of cells positive for all known human functional TLRs, stained using specific antibodies by immunohistochemistry, and evaluated using morphometry. In comparison to osteoarthtritic synovium, the number of TLR-positive cells was found to be increased in the aseptic setting, reflecting the considerable macrophage infiltration to the tissues investigated. Thus aseptic periprosthetic tissue seems to be very reactive to PAMPs. It has been recently recognized that TLR do not only respond to traditional PAMPs, but also to endogenous alarmings or danger signals released from necrotic and activated cells. Alarming-TLR interaction in the periprosthetic tissue might be a novel mechanism of aseptic loosening of endoprosthesis. (c) 2009 Orthopaedic Research Society.

To better understand the roles of leaves at different stem positions during plant development, we measured the physiological properties of leaves 1-4 on maize seedling stems, and performed a proteomics study to investigate the differences in protein expression in the four leaves using two-dimensional difference gel electrophoresis and tandem mass spectrometry in conjunction with database searching. A total of 167 significantly differentially expressed protein spots were found and identified. Of these, 35% are involved in photosynthesis. By further analysis of the data, we speculated that in leaf 1 the seedling has started to transition from a heterotroph to an autotroph, development of leaf 2 is the time at which the seedling fully transitions from a heterotroph to an autotroph, and leaf maturity was reached only with fully expanded leaves 3 and 4, although there were still some protein expression differences in the two leaves. These results suggest that the different leaves make different contributions to maize seedling growth via modulation of the expression of the photosynthetic proteins. Together, these results provide insight into the roles of the different maize leaves as the plant develops from a heterotroph to an autotroph. Copyright © 2016 Elsevier GmbH. All rights reserved.
