Joseph Conrad's Lord Jim: Reconsiderations

Directory of Open Access Journals (Sweden)

Ali Albashir Mohammed Al-Haj

2014-12-01

Full Text Available The present study aims at reconsidering critically Joseph Conrad's Lord Jim. Joseph Conrad is a great master of English prose who writes normally of the sea, of the Eastern islands, of the English character as seen against a background of the exotic or faced with difficulties. The power of Conrad's feelings for Jim, as well as the force of his judgment  against him, are the responses  of a man mightily involved on two planes, one personal and one public , with the dynamics of good and evil. The evil in Lord Jim is one thing on the surface and another beneath our grasp. It is of course the evil of men who have no sense of loyalty to anything.

Comparative Transcriptional Profiling Established the Awn as the Major Photosynthetic Organ of the Barley Spike While the Lemma and the Palea Primarily Protect the Seed

Directory of Open Access Journals (Sweden)

Tilahun Abebe

2009-11-01

Full Text Available The lemma, palea, and awn of a barley ( L. spike are photosynthetic organs that supply the developing seed with carbohydrates. The lemma and palea also enclose the seed and protect it from pathogens and insects. Despite the important roles they play, little information exists on gene expression in these organs that identifies their function. In this study, we compared gene expression among the lemma, palea, awn, and developing seed of barley during grain filling using the Barley1 Genome Array to identify highly expressed genes involved in the primary function of these organs. Hierarchical clustering and mixed model analysis revealed that the lemma and palea have closely related gene expression patterns. In addition, the lemma and palea overexpressed defense-related genes compared with the awn. The awn preferentially expressed genes for photosynthesis, the biosynthesis of chlorophyll and carotenoids, and reactive oxygen species scavenging. This suggests the lemma and palea are mainly protective organs whereas the awn is primarily a photosynthetic structure. The seed was enriched with genes for the biosynthesis of starch, storage proteins, enzyme inhibitors, and cell proliferation.

Thin-wall approximation in vacuum decay: A lemma

Science.gov (United States)

Brown, Adam R.

2018-05-01

The "thin-wall approximation" gives a simple estimate of the decay rate of an unstable quantum field. Unfortunately, the approximation is uncontrolled. In this paper I show that there are actually two different thin-wall approximations and that they bracket the true decay rate: I prove that one is an upper bound and the other a lower bound. In the thin-wall limit, the two approximations converge. In the presence of gravity, a generalization of this lemma provides a simple sufficient condition for nonperturbative vacuum instability.

Juan Ramón Jiménez and Nietzsche

Directory of Open Access Journals (Sweden)

John P. Devlin

1983-01-01

Full Text Available The young Juan Ramón Jiménez shared the enthusiasm for the writings of Nietzsche prevalent among his contemporaries. More significant are the interest in and affinity with Nietzsche which persisted into the poet's maturity. Jiménez found in Nietzsche not only a man of ideas but a poet who claimed to be a potent spiritual force. Both writers held that the modern age could recover a sense of spiritual integrity through the will of the individual to live and interpret human existence as an aesthetic phenomenon. Nietzsche's views on the nature of art and the role of the artist helped to sustain Jiménez' exalted and elitist view of poetry and the poet's mission. Jiménez felt an ethical kinship with the philosopher who asserted the absolute uniqueness of the creative individual, the end of whose existence was self-realization through his art. Nietzsche's doctrine of heroic vitalism as an antidote to chronic spiritual malaise corresponds to Jiménez' revitalized vision of the poetic word proclaimed in the Diario and elaborated in subsequent verse and prose writings.

A Geometric Problem and the Hopf Lemma. Ⅱ

Institute of Scientific and Technical Information of China (English)

YanYan LI; Louis NIRENBERG

2006-01-01

A classical result of A. D. Alexandrov states that a connected compact smooth n-dimensional manifold without boundary, embedded in Rn+1, and such that its mean curvature is constant, is a sphere. Here we study the problem of symmetry of M in a hyperplane Xn+1 =constant in case M satisfies: for any two points (X′, Xn+1), (X′, ^Xn+1)on M, with Xn+1 ＞ ^Hn+1, the mean curvature at the first is not greater than that at the second. Symmetry need not always hold, but in this paper, we establish it under some additional conditions. Some variations of the Hopf Lemma are also presented. Several open problems are described. Part Ⅰ dealt with corresponding one dimensional problems.

Sequence stratigraphic and sedimentologic significance of biogenic structures from a late Paleozoic marginal- to open-marine reservoir, Morrow Sandstone, subsurface of southwest Kansas, USA

Science.gov (United States)

Buatois, L.A.; Mangano, M.G.; Alissa, A.; Carr, T.R.

2002-01-01

Integrated ichnologic, sedimentologic, and stratigraphic studies of cores and well logs from Lower Pennsylvanian oil and gas reservoirs (lower Morrow Sandstone, southwest Kansas) allow distinction between fluvio-estuarine and open marine deposits in the Gentzler and Arroyo fields. The fluvio-estuarine facies assemblage is composed of both interfluve and valley-fill deposits, encompassing a variety of depositional environments such as fluvial channel, interfluve paleosol, bay head delta, estuary bay, restricted tidal flat, intertidal channel, and estuary mouth. Deposition in a brackish-water estuarine valley is supported by the presence of a low diversity, opportunistic, impoverished marine ichnofaunal assemblage dominated by infaunal structures, representing an example of a mixed, depauperate Cruziana and Skolithos ichnofacies. Overall distribution of ichnofossils along the estuarine valley was mainly controlled by the salinity gradient, with other parameters, such as oxygenation, substrate and energy, acting at a more local scale. The lower Morrow estuarine system displays the classical tripartite division of wave-dominated estuaries (i.e. seaward-marine sand plug, fine-grained central bay, and sandy landward zone), but tidal action is also recorded. The estuarine valley displays a northwest-southeast trend, draining to the open sea in the southeast. Recognition of valley-fill sandstones in the lower Morrow has implications for reservoir characterization. While the open marine model predicts a "layer-cake" style of facies distribution as a consequence of strandline shoreline progradation, identification of valley-fill sequences points to more compartmentalized reservoirs, due to the heterogeneity created by valley incision and subsequent infill. The open-marine facies assemblage comprises upper, middle, and lower shoreface; offshore transition; offshore; and shelf deposits. In contrast to the estuarine assemblage, open marine ichnofaunas are characterized by a

An Equivalent LMI Representation of Bounded Real Lemma for Continuous-Time Systems

Directory of Open Access Journals (Sweden)

Xie Wei

2008-01-01

Full Text Available Abstract An equivalent linear matrix inequality (LMI representation of bounded real lemma (BRL for linear continuous-time systems is introduced. As to LTI system including polytopic-type uncertainties, by using a parameter-dependent Lyapunov function, there are several LMIs-based formulations for the analysis and synthesis of performance. All of these representations only provide us with different sufficient conditions. Compared with previous methods, this new representation proposed here provides us the possibility to obtain better results. Finally, some numerical examples are illustrated to show the effectiveness of proposed method.

Lucky Jim is set around 1950s. The novel is under the influence of"Angry Young Men" movement which has encouraged many authors to produce angry novels that criticize the outdated social and political values and condemn the distinctive class differentiation. This essay analyzes the luck and anger of Jim Dixon from the perspective of"Political Unconscious". And the deeper reasons that are dug out behind luck and anger reflect readers' symbolic meditation towards a whole generation of people.

Performing Jim Crow: Blackface Performance and Emancipation (Interpretando a Jim Crow: Blackface y emancipación

Directory of Open Access Journals (Sweden)

Thomas L. King

2015-06-01

Full Text Available Abstract: A nineteenth-century American actor named Thomas Rice was sensationally popular as a blackface character named Jim Crow. His popularity is credited with giving birth to blackface minstrelsy as others began to imitate him in the hope of emulating his success. Rice’s Jim Crow provided a name for laws and customs designed to repudiate the emancipation of African slaves. Blackface minstrelsy staged an idealized version of slave life on a southern plantation. Paradoxically, as blackface revoked the emancipation of slaves on stage, it emancipated the American theatre from its British origins and its audience of recently immigrated laborers from a low social position. It even occasionally performed an ironic reversal of the subaltern status of the very African slaves whose freedom by proclamation and constitutional amendment the performance sought to negate. Contradictions in the history of blackface performance in the United States stage American anxieties about race, class, emancipation, and the very construction of the concepts of blackness and whiteness.Resumen: En el siglo XIX, Thomas Rice, un actor estadounidense, ganó mucha fama haciendo el papel de un personaje cuya cara estaba pintada de negro con el nombre Jim Crow.

El Jim Crow de Rice dio nombre a una serie de leyes y costumbres diseñadas para repudiar la emancipación de esclavos africanos. Los espectáculos de los actores en blackface representaron una versión idealizada de la vida de los esclavos en una hacienda sureña. Paradójicamente, mientras el blackface revocó la emancipación de los esclavos sobre el escenario, emancipó el teatro estadounidense de sus orígenes británicas y su público que consistía en obreros inmigrantes de baja clase social.

The detectability lemma and its applications to quantum Hamiltonian complexity

International Nuclear Information System (INIS)

Aharonov, Dorit; Arad, Itai; Vazirani, Umesh; Landau, Zeph

2011-01-01

Quantum Hamiltonian complexity, an emerging area at the intersection of condensed matter physics and quantum complexity theory, studies the properties of local Hamiltonians and their ground states. In this paper we focus on a seemingly specialized technical tool, the detectability lemma (DL), introduced in the context of the quantum PCP challenge (Aharonov et al 2009 arXiv:0811.3412), which is a major open question in quantum Hamiltonian complexity. We show that a reformulated version of the lemma is a versatile tool that can be used in place of the celebrated Lieb-Robinson (LR) bound to prove several important results in quantum Hamiltonian complexity. The resulting proofs are much simpler, more combinatorial and provide a plausible path toward tackling some fundamental open questions in Hamiltonian complexity. We provide an alternative simpler proof of the DL that removes a key restriction in the original statement (Aharonov et al 2009 arXiv:0811.3412), making it more suitable for the broader context of quantum Hamiltonian complexity. Specifically, we first use the DL to provide a one-page proof of Hastings' result that the correlations in the ground states of gapped Hamiltonians decay exponentially with distance (Hastings 2004 Phys. Rev. B 69 104431). We then apply the DL to derive a simpler and more intuitive proof of Hastings' seminal one-dimensional (1D) area law (Hastings 2007 J. Stat. Mech. (2007) P8024) (both these proofs are restricted to frustration-free systems). Proving the area law for two and higher dimensions is one of the most important open questions in the field of Hamiltonian complexity, and the combinatorial nature of the DL-based proof holds out hope for a possible generalization. Indeed, soon after the first publication of the methods presented here, they were applied to derive exponential improvements to Hastings' result (Arad et al 2011, Aharonov et al 2011) in the case of frustration-free 1D systems. Finally, we also provide a more general

Creativity, alcohol and drug abuse: the pop icon Jim Morrison.

Science.gov (United States)

Holm-Hadulla, Rainer M; Bertolino, Alina

2014-01-01

Alcohol and drug abuse is frequent among performers and pop musicians. Many of them hope that alcohol and drugs will enhance their creativity. Scientific studies are scarce and conclusions limited for methodological reasons. Furthermore, extraordinary creativity can hardly be grasped by empirical-statistical methods. Thus, ideographic studies are necessary to learn from extraordinarily creative persons about the relationship of creativity with alcohol and drugs. The pop icon Jim Morrison can serve as an exemplary case to investigate the interrelation between alcohol and drug abuse and creativity. Morrison's self-assessments in his works and letters as well as the descriptions by others are analyzed under the perspective of creativity research. In the lyrics of Jim Morrison and in biographical descriptions, we can see how Jim Morrison tried to cope with traumatic events, depressive moods and uncontrolled impulses through creative activities. His talent, skill and motivation to write creatively were independent from taking alcohol and drugs. He used alcohol and drugs to transgress restrictive social norms, to broaden his perceptions and to reinforce his struggle for self-actualization. In short, his motivation to create something new and authentic was reinforced by alcohol and drugs. More important was the influence of a supportive group that enabled Morrison's talents to flourish. However, soon the frequent use of high doses of alcohol and drugs weakened his capacity to realize creative motivation. Jim Morrison is an exemplary case showing that heavy drinking and the abuse of LSD, mescaline and amphetamines damages the capacity to realize creative motivation. Jim Morrison is typical of creative personalities like Amy Winehouse, Janis Joplin, Brian Jones and Jimmy Hendrix who burn their creativity in early adulthood through alcohol and drugs. We suppose that the sacrificial ritual of their decay offers some benefits for the excited spectators. One of these is the

Effects of aging, aphasia, and Parkinson’s disease on the time course of lemma selection during sentence production: evidence from eyetracking

Directory of Open Access Journals (Sweden)

Jiyeon Lee

2015-05-01

Full Text Available Sentence production involves intricate coordination of planning and speaking. In the word-by-word incremental model, speakers start their speech upon preparing a single lemma, taxing the pre-speech memory buffer minimally (deSmedt, 1990; Griffin, 2001; Kempen & Hoenkamp, 1987. Alternatively, speakers may prepare multiple words in advance, such as up to the verb (Ferreria, 2000; Lindsley, 1975 or the entire clause (Garret, 1982; Ford, 1982 to avoid producing disfluencies and momentary word retrieval difficulties during speech. Sentence production in young healthy speakers is largely incremental, with some strategic flexibility (Ferreira & Swets, 2000; Schriefers et al., 1998. However, how the time course of lexical selection during sentence production is affected in speakers with reduced cognitive-linguistic capacity remains unclear. The present study examined the effects of aging, aphasia, and Parkinson’s disease (PD on the time course of lemma selection during sentence production, using eyetracking. Data from a group of 16 young, 14 older, 12 PD, and 12 agrammatic aphasic speakers are reported. Young and aphasic speakers’ data are drawn from Lee, Yoshida, & Thompson (accepted to compare with PD and older speakers’ data. Participants described three object pictures (A, B, C using the sentence frame “the A and the B are above the C” (Griffin, 2001. Each picture’s codability (name agreement was manipulated to be high (clock or low (couch/sofa. Speakers experience increased lemma selection difficulty when naming low codable pictures, resulting in increased gaze durations. Participants’ gaze durations to each picture were measured and aligned with the speech onset of sentences to see ‘when’ each lemma was prepared. Results showed that aphasic and PD speakers produced significantly fewer target sentences than young and older speakers, with this difference pronounced only when sentences included low-codable pictures for the PD group

Norms of valence, arousal, and dominance for 13,915 English lemmas.

Science.gov (United States)

Warriner, Amy Beth; Kuperman, Victor; Brysbaert, Marc

2013-12-01

Information about the affective meanings of words is used by researchers working on emotions and moods, word recognition and memory, and text-based sentiment analysis. Three components of emotions are traditionally distinguished: valence (the pleasantness of a stimulus), arousal (the intensity of emotion provoked by a stimulus), and dominance (the degree of control exerted by a stimulus). Thus far, nearly all research has been based on the ANEW norms collected by Bradley and Lang (1999) for 1,034 words. We extended that database to nearly 14,000 English lemmas, providing researchers with a much richer source of information, including gender, age, and educational differences in emotion norms. As an example of the new possibilities, we included stimuli from nearly all of the category norms (e.g., types of diseases, occupations, and taboo words) collected by Van Overschelde, Rawson, and Dunlosky (Journal of Memory and Language 50:289-335, 2004), making it possible to include affect in studies of semantic memory.

The American Serialization of Lord Jim

Stephen Donovan

2017-12-01

Full Text Available This essay presents the discovery of the American serialization of Joseph Conrad’s Lord Jim in New York’s Evening Telegram in 1903. This ‘lost’ serialization, it argues, invites a new perspective on Conrad’s early career by foregrounding the role of newspaper serialization and syndication in establishing his literary standing. After surveying the principal differences in the respective reading experiences of the periodical versus the book, it concludes by proposing that the prominence of women among Conrad’s first audiences requires us to reassess the basis for his success in North America and elsewhere.

Robust Monotonically Convergent Iterative Learning Control for Discrete-Time Systems via Generalized KYP Lemma

Directory of Open Access Journals (Sweden)

Jian Ding

2014-01-01

Full Text Available This paper addresses the problem of P-type iterative learning control for a class of multiple-input multiple-output linear discrete-time systems, whose aim is to develop robust monotonically convergent control law design over a finite frequency range. It is shown that the 2 D iterative learning control processes can be taken as 1 D state space model regardless of relative degree. With the generalized Kalman-Yakubovich-Popov lemma applied, it is feasible to describe the monotonically convergent conditions with the help of linear matrix inequality technique and to develop formulas for the control gain matrices design. An extension to robust control law design against systems with structured and polytopic-type uncertainties is also considered. Two numerical examples are provided to validate the feasibility and effectiveness of the proposed method.

Comparing Free-Free and Shaker Table Model Correlation Methods Using Jim Beam

Science.gov (United States)

Ristow, James; Smith, Kenneth Wayne, Jr.; Johnson, Nathaniel; Kinney, Jackson

2018-01-01

Finite element model correlation as part of a spacecraft program has always been a challenge. For any NASA mission, the coupled system response of the spacecraft and launch vehicle can be determined analytically through a Coupled Loads Analysis (CLA), as it is not possible to test the spacecraft and launch vehicle coupled system before launch. The value of the CLA is highly dependent on the accuracy of the frequencies and mode shapes extracted from the spacecraft model. NASA standards require the spacecraft model used in the final Verification Loads Cycle to be correlated by either a modal test or by comparison of the model with Frequency Response Functions (FRFs) obtained during the environmental qualification test. Due to budgetary and time constraints, most programs opt to correlate the spacecraft dynamic model during the environmental qualification test, conducted on a large shaker table. For any model correlation effort, the key has always been finding a proper definition of the boundary conditions. This paper is a correlation case study to investigate the difference in responses of a simple structure using a free-free boundary, a fixed boundary on the shaker table, and a base-drive vibration test, all using identical instrumentation. The NAVCON Jim Beam test structure, featured in the IMAC round robin modal test of 2009, was selected as a simple, well recognized and well characterized structure to conduct this investigation. First, a free-free impact modal test of the Jim Beam was done as an experimental control. Second, the Jim Beam was mounted to a large 20,000 lbf shaker, and an impact modal test in this fixed configuration was conducted. Lastly, a vibration test of the Jim Beam was conducted on the shaker table. The free-free impact test, the fixed impact test, and the base-drive test were used to assess the effect of the shaker modes, evaluate the validity of fixed-base modeling assumptions, and compare final model correlation results between these

In South Korean ferry disaster in 2014, the captain abandoned the ship with passengers including high school students still aboard. We noticed the resemblance of abandoning the ship with passengers still aboard the ferry (named the Sewol) and the ship Patna, which was full of pilgrims, in Joseph Conrad's novel "Lord Jim." The aim of this study is to see how medical students think about the role of a medical doctor as a captain of a ship by analyzing book reports on Conrad's "Lord Jim." Participants included 49 third-year medical students. Their book reports were analyzed. If placed in the same situation as the character of Jim, 24 students of the 49 respondents answered that they would stay with the passengers, while 18 students indicated they would escape from the ship with the crew. Most of the students thought the role of a doctor in the medical field was like that of a 'captain.' The medical students reported that they wanted to be a doctor who is responsible for his or her patients, highly moral, warm-hearted, honest, and with high self-esteem. In conclusion, we found that "Lord Jim" induced the virtue of 'responsibility' from the medical students. Consequently, "Lord Jim" could be good teaching material for medical humanities.

Tropic and race. Miguel Jiménez López and the Japanese Immigration in Colombia, 1920-1929

Abel Fernando Martínez Martín

2017-01-01

Full Text Available This article discusses the debate on immigration in Colombia, specifically focusing on Japanese immigration, an problem, by being so far from the desired European immigration. Likewise, the important role played by the psychiatrist and conservative Colombian politician Miguel Jiménez Lopez and his theory of degeneration of the Colombian race. Jiménez Lopez is the author of "The yellow immigration in the America", a publication of the National Academy of Medicine, written in response to the Ministry of Industries about the question for the possible impact of a Japanese immigration in the eastern plains. Jiménez Lopez maintains the problem from medicalization and biology, using more arguments from geographical determinism and racism that from eugenics, to justify that a Japanese immigration to Colombia was not advisable, because it jeopardizes the progressive bleaching managed —with the passage of time— by the Colombian race.

GENESIS AND DEVELOPMENT OF A “NONPARTISAN” POLITICAL ACTOR: The Formation of the Jama’ah Islah Malaysia (JIM and its Roots in Western Europe

Full Text Available This paper looks at the genesis and development of the Jama’ah Islah Malaysia (JIM, a modernist-reformist Islamist organisation that today has played a vital and visible role in the political landscape of Malaysian politics. Little is known about the early genesis of JIM, and how it began in the 1970s and 1980s as a student-based cadre organisation, created by Malaysian Muslim students studying abroad in Europe and North America. JIM’s roots therefore lie in the Islamic Representative Council (IRC that was a semi-underground student-cadre movement that was created outside Malaysia, and which aimed to bring about the Islamisation of Malaysian society through the process of social and political mobilisation. Working through the archives of JIM today and interviewing the foundermembers of JIM and the IRC, this paper is the first historical account of the formation and development of IRC and JIM to be published.

Assessment of caprock sealing behavior for secure CO2 storage is a multiscale endeavor. Sealing behavior arises from the nano-scale capillarity of pore throats, but sealing lithologies alone do not guarantee an effective seal since bypass systems, such as connected, conductive fractures can compromise the integrity of the seal. We apply pore-to-formation-scale data to characterize the multiscale caprock sealing behavior of the Morrow shale and Thirteen Finger Limestone. This work is part of the Southwest Regional Partnership on Carbon Sequestration's Phase III project at the Farnsworth Unit, Texas. The caprock formations overlie the Morrow sandstone, the target for enhanced oil recovery and injection of over one million metric tons of anthropogenically-sourced CO2. Methods include: focused ion beam-scanning electron microscopy; laser scanning confocal microscopy; electron and optical petrography; multi-stress path mechanical testing and constitutive modeling; core examinations of sedimentary structures and fractures; and a noble gas profile for formation-scale transport of the sealing lihologies and the reservoir. We develop relationships between diagenetic characteristics of lithofacies to mechanical and petrophysical measurements of the caprocks. The results are applied as part of a caprock sealing behavior performance assessment. Funding for this project is provided by the U.S. Department of Energy's National Energy Technology Laboratory through the Southwest Regional Partnership on Carbon Sequestration (SWP) under Award No. DE-FC26-05NT42591.

About a Class of Positive Hybrid Dynamic Linear Systems and an Associate Extended Kalman-Yakubovich-Popov Lemma

Directory of Open Access Journals (Sweden)

M. De la Sen

2017-01-01

Full Text Available This paper formulates an “ad hoc” robust version under parametrical disturbances of the discrete version of the Kalman-Yakubovich-Popov Lemma for a class of positive hybrid dynamic linear systems which consist of a continuous-time system coupled with a discrete-time or a digital one. An extended discrete system, whose state vector contains both the digital one and the discretization of the continuous-time one at sampling instants, is a key analysis element in the formulation. The hyperstability and asymptotic hyperstability properties of the studied class of positive hybrid systems under feedback from any member of a nonlinear (and, eventually, time-varying class of controllers, which satisfies a Popov’s-type inequality, are also investigated as linked to the positive realness of the associated transfer matrices.

Pinning Synchronization for Complex Networks with Interval Coupling Delay by Variable Subintervals Method and Finsler’s Lemma

Directory of Open Access Journals (Sweden)

Dawei Gong

2017-01-01

Full Text Available The pinning synchronous problem for complex networks with interval delays is studied in this paper. First, by using an inequality which is introduced from Newton-Leibniz formula, a new synchronization criterion is derived. Second, combining Finsler’s Lemma with homogenous matrix, convergent linear matrix inequality (LMI relaxations for synchronization analysis are proposed with matrix-valued coefficients. Third, a new variable subintervals method is applied to expand the obtained results. Different from previous results, the interval delays are divided into some subdelays, which can introduce more free weighting matrices. Fourth, the results are shown as LMI, which can be easily analyzed or tested. Finally, the stability of the networks is proved via Lyapunov’s stability theorem, and the simulation of the trajectory claims the practicality of the proposed pinning control.

Skookum Jim Friendship Centre retrofit training

Energy Technology Data Exchange (ETDEWEB)

1984-08-01

The retrofit/renovation of the Skookum Jim Friendship Centre in Whitehorse, Yukon, provided an ideal opportunity to train ten carpenters as specialists in energy conserving construction at the community level throughout the Yukon. Through this project, the trainees have gained special skills through hands-on experience with many energy conserving materials and techniques. As well, the training sessions provided extensive information on applicable thermodynamic principles and building science technology. The crew of two instructors, ten trainees, and the foreman covered all aspects of residential/light commercial construction which apply to retrofit work. Training sessions included information on site-safety, and interpreting the National Building Code, as well as special attention to the air tightness and insulation levels in the building. In observing the operation of the new building during the first heating season, it was noted that the heat provided by the lighting in the building supplied the majority of space heating requirements. Back-up electrical heating was required only at temperatures approaching design temperature for the building. 6 Figs.

"Mr. Database" : Jim Gray and the History of Database Technologies.

Hanwahr, Nils C

2017-12-01

Although the widespread use of the term "Big Data" is comparatively recent, it invokes a phenomenon in the developments of database technology with distinct historical contexts. The database engineer Jim Gray, known as "Mr. Database" in Silicon Valley before his disappearance at sea in 2007, was involved in many of the crucial developments since the 1970s that constitute the foundation of exceedingly large and distributed databases. Jim Gray was involved in the development of relational database systems based on the concepts of Edgar F. Codd at IBM in the 1970s before he went on to develop principles of Transaction Processing that enable the parallel and highly distributed performance of databases today. He was also involved in creating forums for discourse between academia and industry, which influenced industry performance standards as well as database research agendas. As a co-founder of the San Francisco branch of Microsoft Research, Gray increasingly turned toward scientific applications of database technologies, e. g. leading the TerraServer project, an online database of satellite images. Inspired by Vannevar Bush's idea of the memex, Gray laid out his vision of a Personal Memex as well as a World Memex, eventually postulating a new era of data-based scientific discovery termed "Fourth Paradigm Science". This article gives an overview of Gray's contributions to the development of database technology as well as his research agendas and shows that central notions of Big Data have been occupying database engineers for much longer than the actual term has been in use.

Air pollution in China, one of the world’s oldest civilizations, reflects a combination of traditional and modern-day factors. Severe air pollution in Chinese cities is the result of rapid industrialization, urbanization, and growth in vehicle use. At the same time, traditional indoor burning of solid fuels such as coal and dung presents acute, severe exposures to pollutants including particulate matter, carbon monoxide, arsenic, and mercury. In this podcast, Junfeng (Jim) Zhang tells host Ashley Ahearn about some of the factors that make air pollution a significant problem in China.

The press in Alabama covered major events taking place in Germany from the rise of Adolf Hitler and the Nazis in 1933 through the Nuremberg Trials in 1946. Journalists in the state provided extensive coverage, and editors did not hesitate to opine on the persecution of the Jews in Europe. Yet, Alabama’s white-run press failed in the end to explain the events as a singularly Jewish tragedy. The state’s black-run press, for its part, used the news of the mass killings of the Jews to warn against the dangers of conceptions of racial superiority—a primary concern for black southerners living in the Jim Crow South.

Tourism and the Hispanicization of race in Jim Crow Miami, 1945-1965.

Science.gov (United States)

Rose, Chanelle N

2012-01-01

This article examines how Miami's significant presence of Anglo Caribbean blacks and Spanish-speaking tourists critically influenced the evolution of race relations before and after the watershed 1959 Cuban Revolution. The convergence of people from the American South and North, the Caribbean, and Latin America created a border culture in a city where the influx of Bahamian blacks and Spanish-speakers, especially tourists, had begun to alter the racial landscape. To be sure, Miami had many parallels with other parts of the South in regard to how blackness was understood and enforced by whites during the first half of the twentieth century. However, I argue that the city's post-WWII meteoric tourist growth, along with its emergence as a burgeoning Pan-American metropolis, complicated the traditional southern black-white dichotomy. The purchasing power of Spanish-speaking visitors during the postwar era transformed a tourist economy that had traditionally catered to primarily wealthy white transplanted Northerners. This significant change to the city's tourist industry significantly influenced white civic leaders' decision to occasionally modify Jim Crow practices for Latin American vacationers. In effect, Miami's early Latinization had a profound impact on the established racial order as speaking Spanish became a form of currency that benefited Spanish-speaking tourists—even those of African descent. Paradoxically, this ostensibly peculiar racial climate aided the local struggle by highlighting the idiosyncrasies of Jim Crow while perpetuating the second-class status of native-born blacks.

Enfermedad y muerte de Don Gonzalo Jiménez de Quesada

La lepra es una enfermedad que se caracteriza por la insidia de su presencia, su lenta evolución y la progresiva incapacidad que en sus víctimas causa.

Esto y el temor que ha infundido desde tiempos bíblicos, han hecho que ante ella se haya mantenido una actitud ambivalente de negación hasta donde es posible y de rechazo irracional a quien la padece, por temor al contagio.

Ejemplo de ello es el aura de sagrado misterio que envuelve la leyenda de los padecimientos del Adelantado don Gonzalo Jiménez de Quesada (1509-1579, conquistador del Nuevo Reino de Granada y fundador de Santafé de Bogotá en el año de 1538, muerto a la edad, avanzada para la época, de setenta años.

No se puede afirmar, en forma definitiva, que el conquistador fuera leproso. Se acepta, acogiendo el argumento de autoridad que tiene el primer historiador médico entre nosotros, don Pedro María Ibáñez, quien escribió en 1884, en las Memorias para la Historia de la Medicina en Santa Fe, que en “1579 falleció en la ciudad de Mariquita, y de mal de lepra o elefancía de los

An integral geometry lemma and its applications: The nonlocality of the Pavlov equation and a tomographic problem with opaque parabolic objects

Grinevich, P. G.; Santini, P. M.

2016-10-01

Written in the evolutionary form, the multidimensional integrable dispersionless equations, exactly like the soliton equations in 2+1 dimensions, become nonlocal. In particular, the Pavlov equation is brought to the form v t = v x v y - ∂ x -1 ∂ y [ v y + v x 2], where the formal integral ∂ x -1 becomes the asymmetric integral - int_x^∞ {dx'} . We show that this result could be guessed using an apparently new integral geometry lemma. It states that the integral of a sufficiently general smooth function f( X, Y) over a parabola in the plane ( X, Y) can be expressed in terms of the integrals of f( X, Y) over straight lines not intersecting the parabola. We expect that this result can have applications in two-dimensional linear tomography problems with an opaque parabolic obstacle.

Magnetospheric Plasma Physics : the Impact of Jim Dungey’s Research

CERN Document Server

Southwood, David; Mitton, Simon

2015-01-01

This book makes good background reading for much of modern magnetospheric physics. Its origin was a Festspiel for Professor Jim Dungey, former professor in the Physics Department at Imperial College on the occasion of his 90th birthday, 30 January 2013. Remarkably, although he retired 30 years ago, his pioneering and, often, maverick work in the 50’s through to the 70’s on solar terrestrial physics is probably more widely appreciated today than when he retired. Dungey was a theoretical plasma physicist. The book covers how his reconnection model of the magnetosphere evolved to become the standard model of solar-terrestrial coupling. Dungey’s open magnetosphere model now underpins a holistic picture explaining not only the magnetic and plasma structure of the magnetosphere, but also its dynamics which can be monitored in real time. The book also shows how modern day simulation of solar terrestrial coupling can reproduce the real time evolution of the solar terrestrial system in ways undreamt of in 1961 w...

Mechanical changes caused by CO2-driven cement dissolution in the Morrow B Sandstone at reservoir conditions: Experimental observations

Science.gov (United States)

Wu, Z.; Luhmann, A. J.; Rinehart, A. J.; Mozley, P.; Dewers, T. A.

2017-12-01

Carbon Capture, Utilization and Storage (CCUS) in transmissive reservoirs is a proposed mechanism in reducing CO2 emissions. Injection of CO2 perturbs reservoir chemistry, and can modify porosity and permeability and alter mineralogy. However, little work has been done on the coupling of rock alteration by CO2 injection and the mechanical integrity of the reservoir. In this study, we perform flow-through experiments on calcite- and dolomite-cemented Pennsylvanian Morrow B Sandstone (West Texas, USA) cores. We hypothesize that poikilotopic calcite cement has a larger impact on chemo-mechanical alteration than disseminated dolomite cement given similar CO2 exposure. With one control brine flow-through experiment and two CO2-plus-brine flow-through experiments for each cement composition, flow rates of 0.1 and 0.01 ml/min were applied under 4200 psi pore fluid pressure and 5000 psi confining pressure at 71 °C. Fluid chemistry and permeability data enable monitoring of mineral dissolution. Ultrasonic velocities were measured pre-test using 1.2 MHz source-receiver pairs at 0.5 MPa axial load and show calcite-cemented samples with higher dynamic elastic moduli than dolomite-cemented samples. Velocities measured post-experiment will identify changes from fluid-rock interaction. We plan to conduct cylinder-splitting destructive mechanical test (Brazil test) to measure the pristine and altered tensile strength of different cemented sandstones. The experiments will identify extents to which cement composition and texture control chemo-mechanical degradation of CCUS reservoirs.

However fragmentary and partial the critical opinions of Juan Ramón may be (also outspoken and polemical in nature, they are invaluable as a personal historical and aesthetic guide to about fifty or sixty years of Hispanic literary development (1900-1960. Not to take them into account is to fail to recognize a highly important aspect of his total artistic personality. These varied critical texts are a product of a first rate intelligence and the sensibility of a writer of consummate discrimination who was endowed not only with an excellent memory but also a very special talent for appreciating the authentic. Juan Ramón as a critic is quick to praise (San Juan, Bécquer, Dario, Unamuno and Machado and at the same time strong in his censure of certain contemporaries. Several recently collected volumes of miscellaneous critical materials have resolved the bibliographical muddle for the initial study of this fundamental aspect of the poet, but still particularly important are the expressionistic portraits of Españoles de tres mundos , longer tributes to Valle, Ortega and Villaespesa as well as the extensive lectures delivered in his latter years. Examination of these pages gives us an historical and creative overview of the period in which he lived and worked in addition to original considerations about the evolution of Hispanic poetry. Of course, one of the constant focal points of his literary criticism was the modernist epoch of his early days, a movement or attitude which he considered to be a modern twentieth century renaissance. Together with detailed study of these two areas of historical and aesthetic nature, in the ensuing pages some conclusions are pointed out as to the essence of poetry

A military officer in Rif: Jesús Jiménez Ortoneda (1911-1936

Directory of Open Access Journals (Sweden)

José Luis Villanova

2009-08-01

Full Text Available This paper uses original and for the most part unpublished documentation in order to examine the career of Jesús Jiménez Ortoneda, a highly successful career officer who served in the Spanish Protectorate of Morocco between 1907 and 1936. He occupied important positions in the political administration of the Protectorate (as director of the political section of Melilla’s Oficina Central de Intervenciones and a senior official in the Department of Indigenous Affairs; he was fluent in Arab and Tamazight, and gained a sound knowledge of the geography of the Rif mountains. His military career, in which he achieved the rank of lieutenant colonel, was characterized by his strictly professional attitude. He was one of the few career officers in Africa who were faithful to Spain’s republican government and who did not participate in the military uprising of 1936. This discussion of his career brings into question some well-established ideas concerning Spanish colonial policy in Morocco.

Jim Peters' collapse in the 1954 Vancouver Empire Games marathon.

Noakes, Tim; Mekler, Jackie; Pedoe, Dan Tunstall

2008-08-01

On 7 August 1954, the world 42 km marathon record holder, Jim Peters, collapsed repeatedly during the final 385 metres of the British Empire and Commonwealth Games marathon held in Vancouver, Canada. It has been assumed that Peters collapsed from heatstroke because he ran too fast and did not drink during the race, which was held in windless, cloudless conditions with a dry-bulb temperature of 28 degrees C. Hospital records made available to us indicate that Peters might not have suffered from exertional heatstroke, which classically produces a rectal temperature > 42 degrees C, cerebral effects and, usually, a fatal outcome without vigorous active cooling. Although Peters was unconscious on admission to hospital approximately 60 minutes after he was removed from the race, his rectal temperature was 39.4 degrees C and he recovered fully, even though he was managed conservatively and not actively cooled. We propose that Peters' collapse was more likely due to a combination of hyperthermia-induced fatigue which caused him to stop running; exercise-associated postural hypotension as a result of a low peripheral vascular resistance immediately he stopped running; and combined cerebral effects of hyperthermia, hypertonic hypernatraemia associated with dehydration, and perhaps undiagnosed hypoglycaemia. But none of these conditions should cause prolonged unconsciousness, raising the possibility that Peters might have suffered from a transient encephalopathy, the exact nature of which is not understood.

Full Text Available This study aims to read Jim Jarmusch’s movie Only Lovers Left Alive from the perspective of downfall of industrial capitalism and ecosocialist approach. The movie mainly takes place in Detroit Michigan, which is a symbol of the collapse of Fordism and industrialization. Ecosocialist critique of industrial capitalism has common notions with Jarmusch’s tale. Thus, theoretical framework of this study has been established on ecosocialist paradigm. In the movie, Jarmusch represents vampires as intellectuals with a wide accumulation of culture and knowledge and places his critique of industrialization from their point of view. Multimodal Discourse Analysis was applied to the movie to find out how the movie did use visual and literal signifiers to establish its narrative.

The Irish Phone Home: Reflections of Ireland in Jim Sheridan’s In America

Directory of Open Access Journals (Sweden)

Paula Murphy

2009-03-01

Full Text Available This article analyses Jim Sheridan’s film In America (2002, arguing that the American location reflects back imaginary images of Ireland to its Irish audience, in a manner similar to the mechanism described in Lacan’s discussion of his experiment of the inverted bouquet, which he uses to illustrate the three registers of the human psyche. It explores imaginary, symbolic and real dimensions of identity as they are articulated in the film, showing that, as in Lacan’s experiment, the symbolic dimension, which equates with the position of the human subject as social being, is the most powerful structuring force.  In Sheridan’s film, this dimension is embodied in Steven Spielberg’s film ET, a fictional narrative that allows Johnny, the father of the family, to articulate his grief and begin a new life.  Further, Sheridan’s film suggests that America is the imaginary locus of contemporary Irish identity, and that it can be understood as analogous to the spherical mirror of Lacan’s experiment.

Love stories can be unpredictable: Jules et Jim in the vortex of life.

Science.gov (United States)

Dercole, Fabio; Rinaldi, Sergio

2014-06-01

Love stories are dynamic processes that begin, develop, and often stay for a relatively long time in a stationary or fluctuating regime, before possibly fading. Although they are, undoubtedly, the most important dynamic process in our life, they have only recently been cast in the formal frame of dynamical systems theory. In particular, why it is so difficult to predict the evolution of sentimental relationships continues to be largely unexplained. A common reason for this is that love stories reflect the turbulence of the surrounding social environment. But we can also imagine that the interplay of the characters involved contributes to make the story unpredictable-that is, chaotic. In other words, we conjecture that sentimental chaos can have a relevant endogenous origin. To support this intriguing conjecture, we mimic a real and well-documented love story with a mathematical model in which the environment is kept constant, and show that the model is chaotic. The case we analyze is the triangle described in Jules et Jim, an autobiographic novel by Henri-Pierre Roché that became famous worldwide after the success of the homonymous film directed by François Truffaut.

Full Text Available This study examines verb modes and tenses as well as the predicate structure in «Libro decimosexto» of Bartolomé Jiménez Patón’s Comentarios de erudición in an effort to demonstrate how the text straddles the line between Medieval and Golden Age norms. Jiménez Patón, thus, combines traits already considered archaic at the time, due perhaps to his solid training in grammar and his linguistic awareness, with those modern solutions which, towards the end of the 1500’s, were forging the new Spanish language (that of the «plain style», which he championed, one that was gradually being refined in order to take its place as the language of culture.

The Representational Impasse of Post-Apocalyptic Fiction: The Pesthouse by Jim Crace

Directory of Open Access Journals (Sweden)

Diletta De Cristofaro

2013-05-01

Full Text Available Jim Crace’s The Pesthouse (2007 provides the ideal springboard for a discussion about the apocalypse and representation because the event remains unspecified, a gap in the story, suggesting the presence of epistemological limits. The present article contends that this narrative choice depends on a representational impasse which makes the depiction of the apocalypse and its aftermath impossible and which post-apocalyptic fiction has to address, in order to grant its own existence. The apocalypse is to be considered the ultimate iconoclastic concept, utterly beyond our abilities as image-makers and story-tellers, because it has either to do with the notion of an absolute end or with that of the radical alterity of a new beginning. A theoretical discussion of the impasse, divided, for the purposes of a more detailed analysis, into two dilemmas, is followed by an outline of how The Pesthouse engages with this unrepresentability. On the one hand, the British author deploys what might be defined as the logic of the absent referent, in order to allude to the unrepresentable apocalypse. This remains, in fact, inaccessible to language, and thus absent in the narrative, while several elements point to its absence. On the other hand, Crace uses a typical topos of post-apocalyptic fiction, temporal inversion, namely representing the future as a return to the past, to allude to the radical alterity of the aftermath.

Towards a Poetry of Silence: Stéphane Mallarmé and Juan Ramón Jiménez

Directory of Open Access Journals (Sweden)

Mervyn Coke-Enguídanos

1983-01-01

Full Text Available In an era of apparent dissolution, "la Obra" of Juan Ramón Jiménez, like "l'Oeuvre" of Stéphane Mallarmé, has for its goal the attainment of timelessness. In both poets, the concept of absolute Time—the timelessness of eternal Time—is yoked with the ideal of silence. But this is no ordinary silence, and certainly not the kind that results from inadequacy of expression. It is the silence of perfection, the expression of the ineffable: pure Poetry. Since the poetic language is the silent language of thought, both Mallarmé and Juan Ramón seek to convey the pure idea. In so doing, both must stringently eliminate whatever is not essential in their poetry. The astonishing paradox, central to Mallarmé and Juan Ramón alike, is the urge to create an "unwritten" poetry.

How Many Words Do We Know? Practical Estimates of Vocabulary Size Dependent on Word Definition, the Degree of Language Input and the Participant’s Age

Based on an analysis of the literature and a large scale crowdsourcing experiment, we estimate that an average 20-year-old native speaker of American English knows 42,000 lemmas and 4,200 non-transparent multiword expressions, derived from 11,100 word families. The numbers range from 27,000 lemmas for the lowest 5% to 52,000 for the highest 5%. Between the ages of 20 and 60, the average person learns 6,000 extra lemmas or about one new lemma every 2 days. The knowledge of the words can be as shallow as knowing that the word exists. In addition, people learn tens of thousands of inflected forms and proper nouns (names), which account for the substantially high numbers of ‘words known’ mentioned in other publications.

Improved oil recovery in fluvial dominated deltaic reservoirs of Kansas - Near-term, Class I

2000-06-08

This project involved two demonstration projects, one in a Marrow reservoir located in the southwestern part of the state and the second in the Cherokee Group in eastern Kansas. Morrow reservoirs of western Kansas are still actively being explored and constitute an important resource in Kansas. Cumulative oil production from the Morrow in Kansas is over 400,000,000 bbls. Much of the production from the Morrow is still in the primary stage and has not reached the mature declining state of that in the Cherokee. The Cherokee Group has produced about 1 billion bbls of oil since the first commercial production began over a century ago. It is a billion-barrel plus resource that is distributed over a large number of fields and small production units. Many of the reservoirs are operated close to the economic limit, although the small units and low production per well are offset by low costs associated with the shallow nature of the reservoirs (less than 1000 ft. deep).

Remote sensing evidence of lava-ground ice interactions associated with the Lost Jim Lava Flow, Seward Peninsula, Alaska

Science.gov (United States)

Marcucci, Emma C.; Hamilton, Christopher W.; Herrick, Robert R.

2017-12-01

Thermokarst terrains develop when ice-bearing permafrost melts and causes the overlying surface to subside or collapse. This process occurs widely throughout Arctic regions due to environmental and climatological factors, but can also be induced by localized melting of ground ice by active lava flows. The Lost Jim Lava Flow (LJLF) on the Seward Peninsula of Alaska provides evidence of former lava-ground ice interactions. Associated geomorphic features, on the scale of meters to tens of meters, were identified using satellite orthoimages and stereo-derived digital terrain models. The flow exhibits positive- and mixed-relief features, including tumuli ( N = 26) and shatter rings ( N = 4), as well as negative-relief features, such as lava tube skylights ( N = 100) and irregularly shaped topographic depressions ( N = 1188) that are interpreted to include lava-rise pits and lava-induced thermokarst terrain. Along the margins of the flow, there are also clusters of small peripheral pits that may be the products of meltwater or steam escape. On Mars, we observed morphologically similar pits near lava flow margins in northeastern Elysium Planitia, which suggests a common formation mechanism. Investigating the LJLF may therefore help to elucidate processes of lava-ground ice interaction on both Earth and Mars.

Abstract: The focus of this article is the planning and design of a bilingual, explanatory dictionary for industrial electronics with a clearly delimited and very specific target user in mind. Since the number of lemmas to be treated in the dictionary is limited to 500, special care must be taken to select those lemmas that are relevant for both the purpose of the dictionary and the needs of the target user. It is indicated that the main consideration in the planning of the envisaged dictionary is user-friendliness, as dictated by the intended target users. In this article, a novel approach to the semi-automatic selection of lemmas for inclusion in an LSP dictionary is described. The procedure that is used for the extraction of definitional information from an electronic corpus is also explained.

We provide elementary proofs of Lemmas 7.1 and 7.4 appearing in "The Cartan-Hadamard conjecture and the Little Prince", by B. Kloeckner and G. Kuperberg. The Lemmas play an important role in the derivation of novel isoperimetric inequalities. The original proofs relied on Sage, a symbolic algebra package, to factor certain algebraic varieties into irreducible components.

The Drosophila BTB domain protein Jim Lovell has roles in multiple larval and adult behaviors.

Directory of Open Access Journals (Sweden)

Sonia M Bjorum

Full Text Available Innate behaviors have their origins in the specification of neural fates during development. Within Drosophila, BTB (Bric-a-brac,Tramtrack, Broad domain proteins such as Fruitless are known to play key roles in the neural differentiation underlying such responses. We previously identified a gene, which we have termed jim lovell (lov, encoding a BTB protein with a role in gravity responses. To understand more fully the behavioral roles of this gene we have investigated its function through several approaches. Transcript and protein expression patterns have been examined and behavioral phenotypes of new lov mutations have been characterized. Lov is a nuclear protein, suggesting a role as a transcriptional regulator, as for other BTB proteins. In late embryogenesis, Lov is expressed in many CNS and PNS neurons. An examination of the PNS expression indicates that lov functions in the late specification of several classes of sensory neurons. In particular, only two of the five abdominal lateral chordotonal neurons express Lov, predicting functional variation within this highly similar group. Surprisingly, Lov is also expressed very early in embryogenesis in ways that suggests roles in morphogenetic movements, amnioserosa function and head neurogenesis. The phenotypes of two new lov mutations that delete adjacent non-coding DNA regions are strikingly different suggesting removal of different regulatory elements. In lov(47 , Lov expression is lost in many embryonic neurons including the two lateral chordotonal neurons. lov(47 mutant larvae show feeding and locomotor defects including spontaneous backward movement. Adult lov(47 males perform aberrant courtship behavior distinguished by courtship displays that are not directed at the female. lov(47 adults also show more defective negative gravitaxis than the previously isolated lov(91Y mutant. In contrast, lov(66 produces largely normal behavior but severe female sterility associated with ectopic lov

Borehole geophysical and flowmeter data for eight boreholes in the vicinity of Jim Woodruff Lock and Dam, Lake Seminole, Jackson County, Florida

Science.gov (United States)

Clarke, John S.; Hamrick, Michael D.; Holloway, O. Gary

2011-01-01

Borehole geophysical logs and flowmeter data were collected in April 2011 from eight boreholes to identify the depth and orientation of cavernous zones within the Miocene Tampa Limestone in the vicinity of Jim Woodruff Lock and Dam in Jackson County, Florida. These data are used to assess leakage near the dam. Each of the eight boreholes was terminated in limestone at depths ranging from 84 to 104 feet. Large cavernous zones were encountered in most of the borings, with several exceeding 20-inches in diameter. The cavernous zones generally were between 1 and 5 feet in height, but a cavern in one of the borings reached a height of about 6 feet. The resistivity of limestone layers penetrated by the boreholes generally was less than 1,000 ohm-meters. Formation resistivity near the cavernous zones did not show an appreciable contrast from surrounding bedrock, probably because the bedrock is saturated, owing to its primary permeability. Measured flow rates in the eight boreholes determined using an electromagnetic flowmeter were all less than ±0.1 liter per second. These low flow rates suggest that vertical hydraulic gradients in the boreholes are negligible and that hydraulic head in the various cavernous zones shows only minor, if any, variation.

The split-hull phenotype caused by reduced lemma width and low lignin content is under control of SPH encoding a type-2 13-lipoxygenase and contributes to high dehulling efficiency. Rice hulls consist of two bract-like structures, the lemma and palea. The hull is an important organ that helps to protect seeds from environmental stress, determines seed shape, and ensures grain filling. Achieving optimal hull size and morphology is beneficial for seed development. We characterized the split-hull (sph) mutant in rice, which exhibits hull splitting in the interlocking part between lemma and palea and/or the folded part of the lemma during the grain filling stage. Morphological and chemical analysis revealed that reduction in the width of the lemma and lignin content of the hull in the sph mutant might be the cause of hull splitting. Genetic analysis indicated that the mutant phenotype was controlled by a single recessive gene, sph (Os04g0447100), which encodes a type-2 13-lipoxygenase. SPH knockout and knockdown transgenic plants displayed the same split-hull phenotype as in the mutant. The sph mutant showed significantly higher linoleic and linolenic acid (substrates of lipoxygenase) contents in spikelets compared to the wild type. It is probably due to the genetic defect of SPH and subsequent decrease in lipoxygenase activity. In dehulling experiment, the sph mutant showed high dehulling efficiency even by a weak tearing force in a dehulling machine. Collectively, the results provide a basis for understanding of the functional role of lipoxygenase in structure and maintenance of hulls, and would facilitate breeding of easy-dehulling rice.

Advanced Reservoir Characterization and Development through High-Resolution 3C3D Seismic and Horizontal Drilling: Eva South Marrow Sand Unit, Texas County, Oklahoma

Energy Technology Data Exchange (ETDEWEB)

Wheeler,David M.; Miller, William A.; Wilson, Travis C.

2002-03-11

The Eva South Morrow Sand Unit is located in western Texas County, Oklahoma. The field produces from an upper Morrow sandstone, termed the Eva sandstone, deposited in a transgressive valley-fill sequence. The field is defined as a combination structural stratigraphic trap; the reservoir lies in a convex up -dip bend in the valley and is truncated on the west side by the Teepee Creek fault. Although the field has been a successful waterflood since 1993, reservoir heterogeneity and compartmentalization has impeded overall sweep efficiency. A 4.25 square mile high-resolution, three component three-dimensional (3C3D) seismic survey was acquired in order to improve reservoir characterization and pinpoint the optimal location of a new horizontal producing well, the ESU 13-H.

Morrowan stratigraphy, depositional systems, and hydrocarbon accumulation, Sorrento field, Cheyenne County, Colorado

Energy Technology Data Exchange (ETDEWEB)

Orchard, D.M.; Kidwell, M.R.

1983-08-01

The Sorrento field, located on the western flank of the present-day Las Animas arch in western Cheyenne County, Colorado, has approximately 29 million bbl of oil and 12 bcf of gas in place in sandstones of the Lower Pennsylvanian Morrow units. The sandstones were deposited in a fluvially dominated deltaic system, and the trap for the hydrocarbon accumulation is formed by pinch-out of this deltaic system onto regional dip. The primary reservoirs are point-bar deposits. At the Sorrento field, the basal Keyes limestone member of the Morrow formation rests unconformably on the Mississippian St. Louis Formation. Above the Keyes limestone, the Morrow shale is 180 to 214 ft (55 to 65 m) thick, and locally contains reservoir sands. Gas/oil and oil/water contacts are not uniform through the field owing to discontinuities between separate point bars. One such discontinuity is formed by an apparent mud plug of an abandoned channel separating two point bars on the southeastern end of the field. In a well 7000 ft (2100 m) from the edge of the meander belt, the regressive sequence is represented by a shoreline siltstone unit 8 ft (2 m) thick with flaser bedding, graded bedding, load structures, and rare wave-ripple cross-bedding overlain by 3 ft (1 m) of flood-plain mudstone and coal with no indication of proximity to a nearby sand system.

Failure to Burrow and Tunnel Reveals Roles for jim lovell in the Growth and Endoreplication of the Drosophila Larval Tracheae.

Directory of Open Access Journals (Sweden)

Fanli Zhou

Full Text Available The Drosophila protein Jim Lovell (Lov is a putative transcription factor of the BTB/POZ (Bric- a-Brac/Tramtrack/Broad/ Pox virus and Zinc finger domain class that is expressed in many elements of the developing larval nervous system. It has roles in innate behaviors such as larval locomotion and adult courtship. In performing tissue-specific knockdown with the Gal4-UAS system we identified a new behavioral phenotype for lov: larvae failed to burrow into their food during their growth phase and then failed to tunnel into an agarose substratum during their wandering phase. We determined that these phenotypes originate in a previously unrecognized role for lov in the tracheae. By using tracheal-specific Gal4 lines, Lov immunolocalization and a lov enhancer trap line, we established that lov is normally expressed in the tracheae from late in embryogenesis through larval life. Using an assay that monitors food burrowing, substrate tunneling and death we showed that lov tracheal knockdown results in tracheal fluid-filling, producing hypoxia that activates the aberrant behaviors and inhibits development. We investigated the role of lov in the tracheae that initiates this sequence of events. We discovered that when lov levels are reduced, the tracheal cells are smaller, more numerous and show lower levels of endopolyploidization. Together our findings indicate that Lov is necessary for tracheal endoreplicative growth and that its loss in this tissue causes loss of tracheal integrity resulting in chronic hypoxia and abnormal burrowing and tunneling behavior.

Regulatory role of OsMADS34 in the determination of glumes fate, grain yield and quality in rice

Directory of Open Access Journals (Sweden)

Deyong Ren

2016-12-01

Full Text Available Grasses produce seeds on spikelets, a unique type of inflorescence. Despite the importance of grass crops for food, the genetic mechanisms that control spikelet development remain poorly understood. In this study, we used m34-z, a new mutant allele of the rice (Oryza sativa E-class gene OsMADS34, to examine OsMADS34 function in determining the identities of glumes (rudimentary glume and sterile lemma and grain size. In the m34-z mutant, both the rudimentary glume and sterile lemma were homeotically converted to the lemma-like organs and acquired the lemma identity, suggesting that OsMADS34 plays important roles in the development of glumes. In the m34-z mutant, most of the grains from the secondary panicle branches were decreased in size, compared with grains from wild type, but no differences were observed in the grains from the primary panicle branches. The amylose content and gel consistency, and a seed-setting rate from the secondary panicle branches were reduced in the m34-z mutant. Interesting, transcriptional activity analysis revealed that OsMADS34 protein was a transcription repressor and it may influence grain yield by suppressing the expressions of BG1, GW8, GW2 and GL7 in the m34-z mutant. These findings revealed that OsMADS34 largely affects grain yield by affecting the size of grains from the secondary branches.

Low-sensitivity H ∞ filter design for linear delta operator systems with sampling time jitter

Science.gov (United States)

Guo, Xiang-Gui; Yang, Guang-Hong

2012-04-01

This article is concerned with the problem of designing H ∞ filters for a class of linear discrete-time systems with low-sensitivity to sampling time jitter via delta operator approach. Delta-domain model is used to avoid the inherent numerical ill-condition resulting from the use of the standard shift-domain model at high sampling rates. Based on projection lemma in combination with the descriptor system approach often used to solve problems related to delay, a novel bounded real lemma with three slack variables for delta operator systems is presented. A sensitivity approach based on this novel lemma is proposed to mitigate the effects of sampling time jitter on system performance. Then, the problem of designing a low-sensitivity filter can be reduced to a convex optimisation problem. An important consideration in the design of correlation filters is the optimal trade-off between the standard H ∞ criterion and the sensitivity of the transfer function with respect to sampling time jitter. Finally, a numerical example demonstrating the validity of the proposed design method is given.

Evidence for distinct roles of the SEPALLATA gene LEAFY HULL STERILE1 in Eleusine indica and Megathyrsus maximus (Poaceae).

Science.gov (United States)

Reinheimer, Renata; Malcomber, Simon T; Kellogg, Elizabeth A

2006-01-01

LEAFY HULL STERILE1 (LHS1) is an MIKC-type MADS-box gene in the SEPALLATA class. Expression patterns of LHS1 homologs vary among species of grasses, and may be involved in determining palea and lemma morphology, specifying the terminal floret of the spikelet, and sex determination. Here we present LHS1 expression data from Eleusine indica (subfamily Chloridoideae) and Megathyrsus maximus (subfamily Panicoideae) to provide further insights into the hypothesized roles of the gene. E. indica has spikelets with three to eight florets that mature acropetally; E. indica LHS1 (EiLHS1) is expressed in the palea and lemma of all florets. In contrast, M. maximus has spikelets with two florets that mature basipetally; M. maximus LHS1 (MmLHS1) is expressed in the palea and lemma of the distal floret only. These data are consistent with the hypothesis that LHS1 plays a role in determining palea and lemma morphology and specifies the terminal floret of basipetally maturing grass spikelets. However, LHS1 expression does not correlate with floret sex expression; MmLHS1 is restricted to the bisexual distal floret, whereas EiLHS1 is expressed in both sterile and bisexual floret meristems. Phylogenetic analyses reconstruct a complex pattern of LHS1 expression evolution in grasses. LHS1 expression within the gynoecium has apparently been lost twice, once before diversification of a major clade within tribe Paniceae, and once in subfamily Chloridoideae. These data suggest that LHS1 has multiple roles during spikelet development and may have played a role in the diversification of spikelet morphology.

The Lexicographic Treatment of Sublexical and Multilexical Items in a Northern Sotho Monolingual Dictionary: A Challenge for Lexicographers

Directory of Open Access Journals (Sweden)

Motlokwe Clifford Mphahlele

2011-10-01

Full Text Available

Abstract: Dictionaries have in the past used a word-based approach in which sublexical and multilexical items were not regarded as lemmata. Metalexicography as the theoretical component of lexicography requires that sublexical and multilexical items be lemmatized and treated as independent lemmata in the macrostructure of dictionaries. One of the greater challenges for compiling a better and user-oriented Northern Sotho monolingual dictionary is to treat sublexical and multi-lexical items as macrostructural elements. Treating these items, the lexicographer faces quite a number of challenges. This article proposes possible ways in which sublexical and multilexical elements could be successfully treated in a Northern Sotho monolingual dictionary. Taking stock of these challenges, the writer comes with suggestions that would assist lexicographers in the compi-lation of a user-friendly, lexicon-based monolingual dictionary that would lead users to successful information retrieval.

Models for predicting the inflectional paradigm of Croatian words

Directory of Open Access Journals (Sweden)

Jan Šnajder

2013-12-01

Full Text Available Morphological analysis is a prerequisite for many natural language processing tasks. For inflectionally rich languages such as Croatian, morphological analysis typically relies on a morphological lexicon, which lists the lemmas and their paradigms. However, a real-life morphological analyzer must also be able to handle properly the out-of-vocabulary words. We address the task of predicting the correct inflectional paradigm of unknown Croatian words. We frame this as a supervised machine learning problem: we train a classifier to predict whether a candidate lemma-paradigm pair is correct based on a number of string- and corpus-based features. The candidate lemma-paradigm pairs are generated using a handcrafted morphology grammar. Our aim is to examine the machine learning aspect of the problem: we test a comprehensive set of features and evaluate the classification accuracy using different feature subsets. We show that satisfactory classification accuracy (92% can be achieved with SVM using a combination of string- and corpus-based features. On a per word basis, the F1-score is 53% and accuracy is 70%, which outperforms a frequency-based baseline by a wide margin. We discuss a number of possible directions for future research.

James F. T. Bugental died peacefully at age 92 at his Petaluma, California, home on September 18, 2008. Jim was a leading psychotherapist and a founding father, with Abraham Maslow and others, of humanistic psychology, or the "third force" (in contrast to psychoanalysis and behaviorism). Jim was also the creator, along with Rollo May, of existential-humanistic psychotherapy. Jim was born in Fort Wayne, Indiana, on Christmas Day in 1915. Jim earned his doctorate in 1948 from Ohio State University, where he was influenced by Victor Raimy and George Kelly. After a brief time on the University of California, Los Angeles (UCLA) faculty in psychology, Jim resigned in 1953 to found the first group practice of psychotherapy, Psychological Service Associates, with Alvin Lasko. With Abraham Maslow and others, Jim was a cofounder of the Journal of Humanistic Psychology (JHP) and the Association for Humanistic Psychology in 1961. Jim also wrote many books on the topic of psychotherapy during his lifetime. Jim was a great and bold spirit--his many writings and teachings are cherished today widely, and the field of psychology is much richer for his efforts. 2009 APA, all rights reserved

The Macrostructural Embodiment of Affixes and Technostems in Afrikaans Translation Dictionaries

In this article the inclusion and presentation of sublexical items in Afrikaans translation dictionaries, that is, standard translation desk dictionaries with Afrikaans and English as language pair, are emphasized. The two dictionaries under discussion are Groot Woordeboek/Major Dictionary (MD and Tweetalige Woordeboek/Bilingual Dictionary (BD which belong to this category. The discussion encompasses a critical evaluation of the inclusion and presentation of sublexical lemmas according to present-day metalexicographical approaches. The theoretical discussion concentrates throughout on practical lexicography and articles are therefore evaluated according to theoretical principles.

From the investigation of the macrostructural embodiment of sublexical lemmas in BD and MD, it becomes clear that a wider variety of stems than affixes are included in these dictionaries. Where affixes are included, they are treated more scantily than stems. There is also a need for the inclusion of comprehensive instructions for the user in both dictionaries.

This report presents the answers that an informal and unfunded group at SNL provided for questions concerning computer security posed by Jim Gosler, Sandia Fellow (00002). The primary purpose of this report is to record our current answers; hopefully those answers will turn out to be answers indeed. The group was formed in November 2010. In November 2010 Jim Gosler, Sandia Fellow, asked several of us several pointed questions about computer security metrics. Never mind that some of the best minds in the field have been trying to crack this nut without success for decades. Jim asked Campbell to lead an informal and unfunded group to answer the questions. With time Jim invited several more Sandians to join in. We met a number of times both with Jim and without him. At Jim's direction we contacted a number of people outside Sandia who Jim thought could help. For example, we interacted with IBM's T.J. Watson Research Center and held a one-day, videoconference workshop with them on the questions.

Schmidt games and Markov partitions

Tseng, Jimmy

2009-01-01

Let T be a C 2 -expanding self-map of a compact, connected, C ∞ , Riemannian manifold M. We correct a minor gap in the proof of a theorem from the literature: the set of points whose forward orbits are nondense has full Hausdorff dimension. Our correction allows us to strengthen the theorem. Combining the correction with Schmidt games, we generalize the theorem in dimension one: given a point x 0 in M, the set of points whose forward orbit closures miss x 0 is a winning set. Finally, our key lemma, the no matching lemma, may be of independent interest in the theory of symbolic dynamics or the theory of Markov partitions

“They can’t wipe us out, they can’t lick us. We’ll go on forever pa, ‘cause we’re the people”: Misrepresenting Death in Jim Sheridan’s In America (2003

2008-03-01

Full Text Available This paper will examine the recurring theme of death in Jim Sheridan’s work, with particular focus on his 2003 film In America. This theme also links Sheridan’s work to one of his favourite directors, John Ford, whose work In America alludes to. While exploring the theme of death in Sheridan’s films, and how it connects with the work of Ford, this paper will consider responses to In America, the first film to be (partly shot in New York after the attack on the twin towers, in light of the tragedy of 9/11. It raises questions about the problematic positioning of this film by Sheridan and others not just with respect to the events of that day but also in relation to the 1981 hunger strikes in Northern Ireland. Furthermore, it questions the regressive politics involved in the depiction of the central black character in In America, Mateo, particularly as it relates to this theme of death.

SEMANTIC PROSODY OF WORDS OF EFFECTS IN INDONESIAN

Directory of Open Access Journals (Sweden)

Full Text Available In a cause-and-effect type sentence, the choice of lexis and grammar are of crucial importance. This paper focuses on five near synonymous Indonesian lemmas indicating effect, which are: . In Kamus Besar Bahasa Indonesia[1] (the online version of the Indonesian reference dictionary used in this study, these lemmas are described without any feature of semantic prosody. Does this mean that the prosody of these words is not important? My study has shown otherwise. I, here, have extracted cause-and-effect sentences from the PAN Localization Corpus[2] (the reference corpus employed in this study. The collocates and grammatical constructions show that the semantic prosody of hasil is flexible. However, discussion of my finding shows that the prosody for the rest of the lemmas tends to be negative. This can be seen from statistics showing lexical preferences for words with negative associations and negative grammatical constructions where the effects are negative or unexpected. This holds true the four text types in the corpus (economy, sport, science and international affairs. For this reason, I recommend that the KBBI development team should incorporate this feature in forthcoming versions of the dictionary. [1] www.daring.kbbi.co.id [2] http://www.panl10n.net/indonesia/

Information on the spatial distribution of arabinogalactan proteins (AGPs) in plant organs and tissues during plant reactions to low temperature (LT) is limited. In this study, the extracellular distribution of AGPs in banana leaves and roots, and their changes under LT stress were investigated in two genotypes differing in chilling tolerance, by immuno-techniques using 17 monoclonal antibodies against different AGP epitopes. Changes in total classical AGPs in banana leaves were also tested. The results showed that AGP epitopes recognized by JIM4, JIM14, JIM16, and CCRC-M32 antibodies were primarily distributed in leaf veins, while those recognized by JIM8, JIM13, JIM15, and PN16.4B4 antibodies exhibited predominant sclerenchymal localization. Epitopes recognized by LM2, LM14, and MAC207 antibodies were distributed in both epidermal and mesophyll cells. Both genotypes accumulated classical AGPs in leaves under LT treatment, and the chilling tolerant genotype contained higher classical AGPs at each temperature treatment. The abundance of JIM4 and JIM16 epitopes in the chilling-sensitive genotype decreased slightly after LT treatment, and this trend was opposite for the tolerant one. LT induced accumulation of LM2- and LM14-immunoreactive AGPs in the tolerant genotype compared to the sensitive one, especially in phloem and mesophyll cells. These epitopes thus might play important roles in banana LT tolerance. Different AGP components also showed differential distribution patterns in banana roots. In general, banana roots started to accumulate AGPs under LT treatment earlier than leaves. The levels of AGPs recognized by MAC207 and JIM13 antibodies in the control roots of the tolerant genotype were higher than in the chilling sensitive one. Furthermore, the chilling tolerant genotype showed high immuno-reactivity against JIM13 antibody. These results indicate that several AGPs are likely involved in banana tolerance to chilling injury.

Introduction. The term quasi-algebra was introduced in [2] as an algebra in a monoidal category. Since the associativity constraints in these categories are allowed to be nontrivial, the class of quasi-algebras contains various important examples of non-associative algebras like the octonions and other Cayley algebras [2].

Jim was born in Preston, England, in October 1936. After obtaining a first degree in physics at King’s College, London, he moved to Liverpool to study for his PhD at the university’s synchrocyclotron. This was his first proton-proton scattering experiment, and was also the start of a lifelong friendship with Bert Diddens, who was there as a CERN fellow. In the early 1960s Jim moved to SLAC where he worked with Dave Ritson on electron inelastic scatterings. Ritson greatly appreciated Jim’s calm and systematic approach to any kind of problem he was confronted with.

The Microstructural Treatment of Affixes in Afrikaans Translation Dictionaries

The microstructural treatment of affix lemmata in Afrikaans translation dictionaries is currently inadequate. In the dictionaries under discussion, namely Tweetalige Woordeboek / Bilingual Dictionary (BD and Groot Woordeboek / Major Dictionary (MD which are presently viewed as the leading translation desk-top dictionaries, affixes are included rarely. And if they are included as affix lemmata, their treatment is cursory. BD and MD are not very user-friendly and force the user to rely largely on his/her intuition for the meaning and use of affix lemmata. Consequently these dictionaries do not consistently fulfil their role as sources of information. This article considers a number of information categories according to which the lexicographer should treat affix lemmata in the dictionary so that they may be of value to the user. These categories include semantic information such as polysemy, homonymy and synonymy, etymological information, as well as pronunciation and grammatical information.

Automatic training of lemmatization rules that handle morphological changes in pre-, in- and suffixes alike

DEFF Research Database (Denmark)

Jongejan, Bart; Dalianis, Hercules

2009-01-01

We propose a method to automatically train lemmatization rules that handle prefix, infix and suffix changes to generate the lemma from the full form of a word. We explain how the lemmatization rules are created and how the lemmatizer works. We trained this lemmatizer on Danish, Dutch, English......, German, Greek, Icelandic, Norwegian, Polish, Slovene and Swedish full form-lemma pairs respectively. We obtained significant improvements of 24 percent for Polish, 2.3 percent for Dutch, 1.5 percent for English, 1.2 percent for German and 1.0 percent for Swedish compared to plain suffix lemmatization...... using a suffix-only lemmatizer. Icelandic deteriorated with 1.9 percent. We also made an observation regarding the number of produced lemmatization rules as a function of the number of training pairs....

Reservoir release patterns for hydropower operations at the Aspinall Unit on the Gunnison River, Colorado

International Nuclear Information System (INIS)

Yin, S.C.L.; Sedlacek, J.

1995-05-01

This report presents the development of reservoir release patterns for the Aspinall Unit, which includes Blue Mesa, Morrow Point, and Crystal Reservoirs on the Gunnison River in Colorado. Release patterns were assessed for two hydropower operational scenarios--seasonally adjusted steady flows and seasonally adjusted high fluctuating flows--and three representative hydrologic years--moderate (1987), dry (1989), and wet (1983). The release patterns for the operational scenarios were developed with the aid of monthly, daily, and hourly reservoir operational models, which simulate the linked operation of the three Aspinall Unit reservoirs. Also presented are reservoir fluctuations and downstream water surface elevations corresponding to the reservoir release patterns. Both of the hydropower operational scenarios evaluated are based on the ecological research flows proposed by the US Fish and Wildlife Service for the Aspinall Unit. The first operational scenario allows only seasonally adjusted steady flows (no hourly fluctuations at any dam within one day), whereas the second scenario permits high fluctuating flows from Blue Mesa and Morrow Point Reservoirs during certain times of the year. Crystal Reservoir would release a steady flow within each day under both operational scenarios

Distribution of pectins in the pollen apertures of Oenothera hookeri.velans ster/+ster.

Cell wall pectins are some of the most complex biopolymers known, and yet their functions remain largely mysterious. The aim of this paper was to deepen the study of the spatial pattern of pectin distribution in the aperture of Oenothera hookeri.velans ster/+ster fertile pollen. We used "in situ" immunocytochemical techniques at electron microscopy, involving monoclonal antibodies JIM5 and JIM7 directed against pectin epitopes in fertile pollen grains of Oenothera hookeri.velans ster/+ster. The same region was also analyzed by classical cytochemistry for polysaccharide detection. Immunogold labelling at the JIM7 epitope showed only in mature pollen labelling mainly located at the intine endo-aperture region. Cytoplasmic structures near the plasma membrane of the vegetative cell showed no labelling gold grains. In the same pollen stge the labelling at the JIM5 epitope was mostly confined to a layer located in the limit between the endexine and the ektexine at the level of the border of the oncus. Some tubuli at the base of the ektexine showed also an accumulation of gold particles. No JIM5 label was demonstrated in the aperture chamber and either in any cytoplasmic structure of the pollen grains. The immunocytochemical technique, when compared with the traditional methods for non-cellulose polysaccharide cytochemistry is fare more sensitive and allows the univocal determination of temporal and spatial location of pectins recognized by the JIM7 and JIM5 MAbs.

Genetic divergence of a sympatric lake-resident-anadromous three-spined stickleback Gasterosteus aculeatus species pair.

Drevecky, C J; Falco, R; Aguirre, W E

2013-07-01

The genetic relationship between sympatric, morphologically divergent populations of anadromous and lake-resident three-spined stickleback Gasterosteus aculeatus in the Jim Creek drainage of Cook Inlet, Alaska, was examined using microsatellite loci and mitochondrial d-loop sequence data. Resident samples differed substantially from sympatric anadromous samples in the Jim Creek drainage with the magnitude of the genetic divergence being similar to that between allopatric resident and anadromous populations in other areas. Resident samples were genetically similar within the Jim Creek drainage, as were the anadromous samples surveyed. Neighbour-joining and Structure cluster analysis grouped the samples into four genetic clusters by ecomorph (anadromous v. all resident) and geographic location of the resident samples (Jim Creek, Mat-Su and Kenai). There was no evidence of hybridization between resident and anadromous G. aculeatus in the Jim Creek drainage, which thus appear to be reproductively isolated. © 2013 The Authors.

Investigations on photosynthetic pigments of Lemnaceae, pt. 14: The effect of UV-B radiation on deetiolating and autotrophically growing plants of Lemna gibba L

International Nuclear Information System (INIS)

Wejnar, R.; Döhler, D.

1992-01-01

In deetiolating plants of Lemma gibba L., the biosynthesis of photosynthetically active pigments (chlorophyll a and b, beta-carotene, lutein, violaxanthin and neoxanthin) was reduced by UV-B radiation (2,5 W cnt * m -2 ) in dependence on the exposure time (8-96-h). The biosynthesis of chlorophyll b was more inhibited than that of chlorophyll a, that of the chlorophylls more than that of the carotenoids and that of beta-carotene more than that of the xanthophylls notably lutein. In autotrophic plants. UV-B radiation (42, 72 and 120 h) causes a strong reduction of the pigment content. The alteration of the ratios between the pigments was the same as in deetiolating plants. In deetiolating as well as in autotropically cultivated plants of Lemma gibba, the termination of the UV-B radiation is followed by an approach to the original ratios

AmAMorph: Finite State Morphological Analyzer for Amazighe

Directory of Open Access Journals (Sweden)

Fatima Zahra Nejme

2016-03-01

Full Text Available This paper presents AmAMorph, a morphological analyzer for Amazighe language using a system based on the NooJ linguistic development environment. The paper begins with the development of Amazighe lexicons with large coverage formalization. The built electronic lexicons, named ‘NAmLex’, ‘VAmLex’ and ‘PAmLex’ which stand for ‘Noun Amazighe Lexicon’, ‘Verb Amazighe Lexicon’ and ‘Particles Amazighe Lexicon’, link inflectional, morphological, and syntacticsemantic information to the list of lemmas. Automated inflectional and derivational routines are applied to each lemma producing over inflected forms. To our knowledge,AmAMorph is the first morphological analyzer for Amazighe. It identifies the component morphemes of the forms using large coverage morphological grammars. Along with the description of how the analyzer is implemented, this paper gives an evaluation of the analyzer.

Cellular and molecular changes associated with somatic embryogenesis induction in Agave tequilana.

Portillo, L; Olmedilla, A; Santacruz-Ruvalcaba, F

2012-10-01

In spite of the importance of somatic embryogenesis for basic research in plant embryology as well as for crop improvement and plant propagation, it is still unclear which mechanisms and cell signals are involved in acquiring embryogenic competence by a somatic cell. The aim of this work was to study cellular and molecular changes involved in the induction stage in calli of Agave tequilana Weber cultivar azul in order to gain more information on the initial stages of somatic embryogenesis in this species. Cytochemical and immunocytochemical techniques were used to identify differences between embryogenic and non-embryogenic cells from several genotypes. Presence of granular structures was detected after somatic embryogenesis induction in embryogenic cells; composition of these structures as well as changes in protein and polysaccharide distribution was studied using Coomassie brilliant blue and Periodic Acid-Schiff stains. Distribution of arabinogalactan proteins (AGPs) and pectins was investigated in embryogenic and non-embryogenic cells by immunolabelling using anti-AGP monoclonal antibodies (JIM4, JIM8 and JIM13) as well as an anti-methyl-esterified pectin-antibody (JIM7), in order to evaluate major modifications in cell wall composition in the initial stages of somatic embryogenesis. Our observations pointed out that induction of somatic embryogenesis produced accumulation of proteins and polysaccharides in embryogenic cells. Presence of JIM8, JIM13 and JIM7 epitopes were detected exclusively in embryogenic cells, which supports the idea that specific changes in cell wall are involved in the acquisition of embryogenic competence of A. tequilana.

2009-01-01

It was with shock and sorrow that we heard Jim Allaby passed away on 7 April. Jim was born in Preston, England, in October 1936. After obtaining a first degree in physics at King’s College, London, he moved to Liverpool to study for his PhD at the university’s synchrocyclotron. This was his first proton-proton scattering experiment, and was also the start of a lifelong friendship with Bert Diddens, who was there as a CERN fellow. In the early 1960s Jim moved to SLAC where he worked with Dave Ritson on electron inelastic scatterings. Ritson greatly appreciated Jim’s calm and systematic approach to any kind of problem he was confronted with. Thus it was natural for Jim to visit SLAC later and for Ritson to join the DELPHI Collaboration in the 1990s. Jim came to CERN in the summer of 1965. He joined the CERN group of Giuseppe Cocconi, Bert Diddens and Alan Wetherell, who were preparing proton-proton scattering experiments, in a s...

2015-04-15

We develop a newapproach on the (1 + 3) threading of spacetime (M, g) with respect to a congruence of curves defined by an arbitrary timelike vector field. The study is based on spatial tensor fields and on theRiemannian spatial connection ∇*, which behave as 3D geometric objects. We obtain new formulas for local components of the Ricci tensor field of (M, g) with respect to the threading frame field, in terms of the Ricci tensor field of ∇* and of kinematic quantities. Also, new expressions for time covariant derivatives of kinematic quantities are stated. In particular, a new form of Raychaudhuri's equation enables us to prove Lemma 6.3, which completes a well-known lemma used in the proof of the Penrose-Hawking singularity theorems. Finally, we apply the new (1 + 3) formalism to the study of the dynamics of a Kerr-Newman black hole. (orig.)

Optimum harvest maturity for Leymus chinensis seed

Directory of Open Access Journals (Sweden)

Jixiang Lin

2016-06-01

Full Text Available Timely harvest is critical to achieve maximum seed viability and vigour in agricultural production. However, little information exists concerning how to reap the best quality seeds of Leymus chinensis, which is the dominant and most promising grass species in the Songnen Grassland of Northern China. The objective of this study was to investigate and evaluate possible quality indices of the seeds at different days after peak anthesis. Seed quality at different development stages was assessed by the colours of the seed and lemmas, seed weight, moisture content, electrical conductivity of seed leachate and germination indices. Two consecutive years of experimental results showed that the maximum seed quality was recorded at 39 days after peak anthesis. At this date, the colours of the seed and lemmas reached heavy brown and yellow, respectively. The seed weight was highest and the moisture content and the electrical conductivity of seed leachate were lowest. In addition, the seed also reached its maximum germination percentage and energy at this stage, determined using a standard germination test (SGT and accelerated ageing test (AAT. Thus, Leymus chinensis can be harvested at 39 days after peak anthesis based on the changes in parameters. Colour identification can be used as an additional indicator to provide a more rapid and reliable measure of optimum seed maturity; approximately 10 days after the colour of the lemmas reached yellow and the colour of the seed reached heavy brown, the seed of this species was suitable for harvest.

2009-01-01

James N. Kile, of Needham Heights, Massachusetts, died on 17 August 2007, following a brave two-year battle with cancer. One of three children of David R. Kile and Betty Jane Kile, Jim was born in Niagara Falls, New York, on 20 April 1958 and lived in the nearby village of Lewiston before his family settled in Alden, an hour east of Niagara Falls, when Jim was nine. Jim's father worked for American Telephone and Telegraph for 37 years, and his mother was a homemaker. Jim earned his Bachelor's degree in Physics from Rensselaer Polytechnic Institute in 1980, a Master's degree from Northwestern University in 1982, and a Doctorate from Tufts University in 1996 under the direction of Robert Willson. His thesis involved comparison of radio data from the Very Large Array and the Russian RATAN 600 telescope with Yohkoh soft X-ray data, with an emphasis on understanding the relationship between solar noise storms and coronal magnetic fields. While working on his thesis, Jim collaborated with one of us (EWC) at the Air Force Research Laboratory on an investigation of the 154-day periodicity in solar flares. The resulting publication (ApJ 370, 442, 1991) is his most cited work. Jim co-authored four other papers in refereed journals. Jim's professional affiliations included the American Astronomical Society, the American Institute of Aeronautics and Astronautics, the American Geophysical Union, and the Astronomical Society of the Pacific. Jim worked as a contractor in the defense industry from 1982 until the time of his death, settling in the Boston area in the early 1980s. He worked for Calspan Corporation from 1982-1989, the Ultra Corporation from 1989-1994, and the Riverside Research Institute from 1994-2007. He was a highly-respected expert in radar systems, including radar data and systems analysis, systems engineering, and planning support for radar acquisition programs and technology development. The work entailed frequent extended travel to Norway for system testing

Full Text Available Abstract Background Hydroxyproline rich glycoproteins (HRGPs are implicated to have a role in many aspects of plant growth and development but there is limited knowledge about their localization and function during somatic embryogenesis of higher plants. In this study, the localization and function of hydroxyproline rich glycoproteins in embryogenic cells (ECs and somatic embryos of banana were investigated by using immunobloting and immunocytochemistry with monoclonal JIM11 and JIM20 antibodies as well as by treatment with 3,4-dehydro-L-proline (3,4-DHP, an inhibitor of extensin biosynthesis, and by immunomodulation with the JIM11 antibody. Results Immunofluorescence labelling of JIM11 and JIM20 hydroxyproline rich glycoprotein epitopes was relatively weak in non-embryogenic cells (NECs, mainly on the edge of small cell aggregates. On the other hand, hydroxyproline rich glycoprotein epitopes were found to be enriched in early embryogenic cells as well as in various developmental stages of somatic embryos. Embryogenic cells (ECs, proembryos and globular embryos showed strong labelling of hydroxyproline rich glycoprotein epitopes, especially in their cell walls and outer surface layer, so-called extracellular matrix (ECM. This hydroxyproline rich glycoprotein signal at embryo surfaces decreased and/or fully disappeared during later developmental stages (e.g. pear-shaped and cotyledonary stages of embryos. In these later developmental embryogenic stages, however, new prominent hydroxyproline rich glycoprotein labelling appeared in tri-cellular junctions among parenchymatic cells inside these embryos. Overall immunofluorescence labelling of late stage embryos with JIM20 antibody was weaker than that of JIM11. Western blot analysis supported the above immunolocalization data. The treatment with 3,4-DHP inhibited the development of embryogenic cells and decreased the rate of embryo germination. Embryo-like structures, which developed after 3,4-DHP

Evaluation of uncertainty in the measurement of sense of natural language constructions

Directory of Open Access Journals (Sweden)

Bisikalo Oleg V.

2017-01-01

Full Text Available The task of evaluating uncertainty in the measurement of sense in natural language constructions (NLCs was researched through formalization of the notions of the language image, formalization of artificial cognitive systems (ACSs and the formalization of units of meaning. The method for measuring the sense of natural language constructions incorporated fuzzy relations of meaning, which ensures that information about the links between lemmas of the text is taken into account, permitting the evaluation of two types of measurement uncertainty of sense characteristics. Using developed applications programs, experiments were conducted to investigate the proposed method to tackle the identification of informative characteristics of text. The experiments resulted in dependencies of parameters being obtained in order to utilise the Pareto distribution law to define relations between lemmas, analysis of which permits the identification of exponents of an average number of connections of the language image as the most informative characteristics of text.

Adding part-of-speech information to the SUBTLEX-US word frequencies.

Science.gov (United States)

Brysbaert, Marc; New, Boris; Keuleers, Emmanuel

2012-12-01

The SUBTLEX-US corpus has been parsed with the CLAWS tagger, so that researchers have information about the possible word classes (parts-of-speech, or PoSs) of the entries. Five new columns have been added to the SUBTLEX-US word frequency list: the dominant (most frequent) PoS for the entry, the frequency of the dominant PoS, the frequency of the dominant PoS relative to the entry's total frequency, all PoSs observed for the entry, and the respective frequencies of these PoSs. Because the current definition of lemma frequency does not seem to provide word recognition researchers with useful information (as illustrated by a comparison of the lemma frequencies and the word form frequencies from the Corpus of Contemporary American English), we have not provided a column with this variable. Instead, we hope that the full list of PoS frequencies will help researchers to collectively determine which combination of frequencies is the most informative.

General H-theorem and Entropies that Violate the Second Law

Directory of Open Access Journals (Sweden)

Alexander N. Gorban

2014-04-01

Full Text Available H-theorem states that the entropy production is nonnegative and, therefore, the entropy of a closed system should monotonically change in time. In information processing, the entropy production is positive for random transformation of signals (the information processing lemma. Originally, the H-theorem and the information processing lemma were proved for the classical Boltzmann-Gibbs-Shannon entropy and for the correspondent divergence (the relative entropy. Many new entropies and divergences have been proposed during last decades and for all of them the H-theorem is needed. This note proposes a simple and general criterion to check whether the H-theorem is valid for a convex divergence H and demonstrates that some of the popular divergences obey no H-theorem. We consider systems with n states Ai that obey first order kinetics (master equation. A convex function H is a Lyapunov function for all master equations with given equilibrium if and only if its conditional minima properly describe the equilibria of pair transitions Ai ⇌ Aj . This theorem does not depend on the principle of detailed balance and is valid for general Markov kinetics. Elementary analysis of pair equilibria demonstrate that the popular Bregman divergences like Euclidian distance or Itakura-Saito distance in the space of distribution cannot be the universal Lyapunov functions for the first-order kinetics and can increase in Markov processes. Therefore, they violate the second law and the information processing lemma. In particular, for these measures of information (divergences random manipulation with data may add information to data. The main results are extended to nonlinear generalized mass action law kinetic equations.

Detrital Zircon Geo- and Thermochronologic Constraints on Late Mississippian-Early Pennsylvanian Sediment Transport and Tectonics, Southwestern Kansas and Northwestern Arkansas

Science.gov (United States)

Bidgoli, T. S.; Wang, W.; Moeller, A.; Stockli, D. F.; Watney, L.

2017-12-01

The Late Mississippian to Early Pennsylvanian is a critical time interval across the globe, with major changes in tectonics, climate, and eustacy. Transcontinental sediment transport in North America, from the Appalachians to Great Canyon, has been proposed to initiate at this time (Gehrels et al., 2011). In the midcontinent, clastic influx to the Hugoton Embayment and Arkoma Shelf, during widespread carbonate platform deposition, may record evidence for this model, but the limited number of provenance studies has hindered interpretations. To test this model and further constrain sediment dispersal and source-to-sink systems in the midcontinent, we evaluate the provenance of upper Mississippian to middle Pennsylvanian siliciclastic intervals, in two areas, using sandstone component analysis and detrital zircon U-Pb and (U-Th)/He double dating. (1) For the Hugoton Embayment in southwestern Kansas, we focus on sandstones deposited in two valley-filling intervals, the Chester and Morrow. A total of 1100 zircon U-Pb ages have been acquired from samples from 10 boreholes, 6 from Chester and 4 from Morrow. Preliminary analysis suggests that the Chester is characterized by two major zircon U-Pb age clusters of 900-1295 Ma (Grenville) and 390-475 Ma, consistent with sediment delivery from the Appalachian orogen. Morrow strata record a change in provenance, with the presence of two additional age groups, 1300-1500 Ma (24.5%) and 1600-1800 Ma (17.9%), that correspond well with the age of basement rocks in the Granite-Rhyolite and Yavapai-Maztzal provinces, respectively. We ascribe changes in the zircon age spectra and introduction of these grains to the development of local uplifts, like the Nemaha Ridge, in the early Pennsylvanian. Double dating of zircons from these peaks may reveal additional information about these basement sources and the timing of denudation of these uplifts. (2) For the Arkoma shelf, we are analyzing 11 samples, collected from outcrops in northwestern

The Treatment of Polysemy and Homonymy in Monolingual General-purpose Dictionaries with Special Reference to Isichazamazwi SesiNdebele

Directory of Open Access Journals (Sweden)

Eventhough Ndlovu

2011-10-01

Full Text Available

ABSTRACT: This article focuses on the treatment of polysemy and homonymy in general-purpose monolingual dictionaries with special reference to Isichazamazwi SesiNdebele. It was found that there are some inconsistencies in the treatment of polysemous and homonymous entries in this dictionary. The article shows that an overreliance on one criterion, particularly etymology, to distinguish polysemy and homonymy is often misleading and unreliable. Polysemy itself has its own inherent complexities, among these being the problem of determining the exact number of meanings of a polysemous lemma. When the meanings of a polysemous lemma are listed, the central or primary meaning, which is not always easily ascertainable, should come first. A holistic approach is proposed to distinguish polysemy and homonymy, which entails the use of the following criteria: etymology, relatedness vs unrelatedness of meaning, componential analysis, the identification of the central or core meaning and the test of ambiguity. Whatever results are obtained from a particular criterion, these findings must be compared with those of other criteria, and verified against native speakers' intuitive knowledge and introspective judgements.

Ice caps in Antarctica or Greenland have recorded the anthropogenic effect on atmospheric composition and especially on greenhouse effect gases such as carbon dioxide and methane. 2000 meter depth drilling samples allowed to study the climates for 150 000 years ago; hot and cold climates are ruled by periodic movement of the Earth around the sun and by more or less elevated concentration of greenhouse effect gases in the atmosphere. Prospects for to morrow climates and anthropogenic contribution are then possible [fr

The emergence of recombinant DNA technology during the early 70's set a revolution in molecular biology. This set of techniques was strengthened even further later on with the introduction of the polymerase chain reaction and allowed scientists to explore and understand essential life processes in an easy and straightforward way. It also marked the birth of the modern biotech industry. At that time, it was shown that eukaryotic DNA could be propagated in Escherichia coli (Morrow et al., 1974)...

Seed dormancy, seedling establishment and dynamics of the soil seed bank of Stipa bungeana (Poaceae on the Loess Plateau of northwestern China.

Directory of Open Access Journals (Sweden)

Xiao Wen Hu

Full Text Available Studying seed dormancy and its consequent effect can provide important information for vegetation restoration and management. The present study investigated seed dormancy, seedling emergence and seed survival in the soil seed bank of Stipa bungeana, a grass species used in restoration of degraded land on the Loess Plateau in northwest China. Dormancy of fresh seeds was determined by incubation of seeds over a range of temperatures in both light and dark. Seed germination was evaluated after mechanical removal of palea and lemma (hulls, chemical scarification and dry storage. Fresh and one-year-stored seeds were sown in the field, and seedling emergence was monitored weekly for 8 weeks. Furthermore, seeds were buried at different soil depths, and then retrieved every 1 or 2 months to determine seed dormancy and seed viability in the laboratory. Fresh seeds (caryopses enclosed by palea and lemma had non-deep physiological dormancy. Removal of palea and lemma, chemical scarification, dry storage (afterripening, gibberellin (GA3 and potassium nitrate (KNO3 significantly improved germination. Dormancy was completely released by removal of the hulls, but seeds on which hulls were put back to their original position germinated to only 46%. Pretreatment of seeds with a 30% NaOH solution for 60 min increased germination from 25% to 82%. Speed of seedling emergence from fresh seeds was significantly lower than that of seeds stored for 1 year. However, final percentage of seedling emergence did not differ significantly for seeds sown at depths of 0 and 1 cm. Most fresh seeds of S. bungeana buried in the field in early July either had germinated or lost viability by September. All seeds buried at a depth of 5 cm had lost viability after 5 months, whereas 12% and 4% seeds of those sown on the soil surface were viable after 5 and 12 months, respectively.

Fusarium head blight (FHB) in wheat and other small grain cereals is a globally devastating disease caused by toxigenic Fusarium pathogens. Controlling FHB is a challenge because germplasm that is naturally resistant against these pathogens is inadequate. Current control measures rely on fungicides. Here, an antibody fusion comprised of the Fusarium spp.-specific recombinant antibody gene CWP2 derived from chicken, and the endochitinase gene Ech42 from the biocontrol fungus Trichoderma atroviride was introduced into the elite wheat cultivar Zhengmai9023 by particle bombardment. Expression of this fusion gene was regulated by the lemma/palea-specific promoter Lem2 derived from barley; its expression was confirmed as lemma/palea-specific in transgenic wheat. Single-floret inoculation of independent transgenic wheat lines of the T3 to T6 generations revealed significant resistance (type II) to fungal spreading, and natural infection assays in the field showed significant resistance (type I) to initial infection. Gas chromatography-mass spectrometry analysis revealed marked reduction of mycotoxins in the grains of the transgenic wheat lines. Progenies of crosses between the transgenic lines and the FHB-susceptible cultivar Huamai13 also showed significantly enhanced FHB resistance. Quantitative real-time PCR analysis revealed that the tissue-specific expression of the antibody fusion was induced by salicylic acid drenching and induced to a greater extent by F. graminearum infection. Histochemical analysis showed substantial restriction of mycelial growth in the lemma tissues of the transgenic plants. Thus, the combined tissue-specific and pathogen-inducible expression of this Fusarium-specific antibody fusion can effectively protect wheat against Fusarium pathogens and reduce mycotoxin content in grain. © 2014 Society for Experimental Biology, Association of Applied Biologists and John Wiley & Sons Ltd.

The problem of the universal density functional and the density matrix functional theory

International Nuclear Information System (INIS)

Bobrov, V. B.; Trigger, S. A.

2013-01-01

The analysis in this paper shows that the Hohenberg-Kohn theorem is the constellation of two statements: (i) the mathematically rigorous Hohenberg-Kohn lemma, which demonstrates that the same ground-state density cannot correspond to two different potentials of an external field, and (ii) the hypothesis of the existence of the universal density functional. Based on the obtained explicit expression for the nonrel-ativistic particle energy in a local external field, we prove that the energy of the system of more than two non-interacting electrons cannot be a functional of the inhomogeneous density. This result is generalized to the system of interacting electrons. It means that the Hohenberg-Kohn lemma cannot provide justification of the universal density functional for fermions. At the same time, statements of the density functional theory remain valid when considering any number of noninteracting ground-state bosons due to the Bose condensation effect. In the framework of the density matrix functional theory, the hypothesis of the existence of the universal density matrix functional corresponds to the cases of noninteracting particles and to interaction in the Hartree-Fock approximation.

Who Knew? Hospice Is a Business. What that Means for All of Us.

Science.gov (United States)

Rahman, Anna N

2017-02-01

A seasoned gerontologist whose work has explored end-of-life care, I thought I knew what I was getting into when I undertook care for my brother Jim. In April 2014, Jim, whose health was then declining rapidly due to liver cancer, moved from his apartment in Minneapolis to my house in Santa Monica. Jim had come for a liver transplant evaluation at the University of California, Los Angeles (UCLA). When the UCLA team declined to list him-his cancer was just too widespread-Jim elected to stay with my family and me, enrolling in hospice. I did my homework when shopping for a hospice provider. Colleagues in the field gave me referrals. I googled their recommendations and read the reviews. I interviewed admissions counselors. When Jim signed the admission papers, I was confident that we were in good hands with the agency we selected. For the most part, we were. Hospice is widely considered an effective program. Studies show that it prevents pain and suffering among dying patients and increases satisfaction with care. Although other health care programs are regularly pilloried in the press, hospice programs are often lauded. Indeed, they sometimes appear so mission driven that one might mistake them for charities. They are not. Whether for-profit or not-for-profit enterprises, they are businesses-and concerned about their bottom line. Through Jim's story and mine, this article highlights the implications of this business orientation for patients and providers. Methods for evaluating hospice programs nationally are critiqued. Finally, recommendations for improving the business of hospice care are offered. © The Author 2016. Published by Oxford University Press on behalf of The Gerontological Society of America.

A tribute to James A. Holcombe

Sturgeon, Ralph

2015-03-01

My first interaction with Jim Holcombe was by letter in late 1977 (well before our instant e-mail communications age we all enjoy and/or curse). Jim was enquiring via some subtle questions about a paper I had recently published in Analytical Chemistry on the mechanisms of atomization in the graphite furnace. This brief correspondence initiated a 35 year period of technical interaction and friendship which literally carried us throughout the world to many conferences and more than a few shared hotel rooms in the days when one would make sacrifices to reduce travel costs to enable conference attendance. At the SciX 2013 (FACSS) meeting in Milwaukee WI, a special symposium was organized by John Molloy in honor of Jim's achievements. This was the closest "public" venue to correspond with Jim's announced 2013 spring retirement and his "exit" from a working career at the Department of Chemistry, University of Texas at Austin. It was a distinct honor for me to have Nicolo Omenetto ask if I would help coordinate this special issue of Spectrochim. Acta, Part B in honor of Jim's career/achievements. This gives me the opportunity to publicly comment on my personal association with this "Texas" gentleman from Colorado, a genuine "out of the box" thinker, a productive, highly acknowledged but humble character that I am grateful to have known, and with whom I have traveled the world and enjoyed so many good times.

Obituary: James Houck (1940 - 2015)

Science.gov (United States)

Weedman, Daniel; Barry, Donald; Soifer, Thomas

James R. Houck, the leading figure in developing infrared spectroscopy for astrophysics, died in Ithaca, NY, on September 18, 2015, at age 74 from complications of Alzheimer's Disease. He was born on October 5, 1940, in Mobile, Alabama, but lived much of his early life in Pittsburgh, Pennsylvania, where he received his undergraduate degree from Carnegie Institute of Technology. Jim spent his scientific career at Cornell University. He came to Cornell as a physics graduate student in 1962 and remained until his retirement as the Kenneth A. Wallace Professor of Astronomy in 2012. His only year away from Ithaca was as a Guggenheim Fellow at Caltech, and he declined job offers from other universities because of his opinion that Ithaca provided the best environment for raising his family. His passion for learning, doing, and teaching science by building instruments and understanding physics led to great benefits for his students and astronomy colleagues. After receiving his PhD in condensed matter physics, he changed fields to work in astronomy at Cornell. He first collaborated with colleague Martin Harwit to develop a rocket program at Cornell for infrared observations and made numerous treks to the White Sands Missile Range flying payloads on Aerobee sounding rockets. Jim emphasized building spectrographs and making pioneering observations with ground based, airborne, and rocket-borne infrared instrumentation. Jim flew on every airplane NASA provided for astronomy. Those were pioneering times. One of his survival stories was of the Learjet in which both engines flamed out over the Pacific when the pilot did a celebratory barrel role after successful completion of their observations. His observations with rockets and airplanes were primarily of a variety of Galactic objects, including planetary nebulae, HII regions, and stars. But the most notable was an observation on the Convair 990 that produced a prescient discovery paper in 1973 led by Jim which discovered bound

Early local differentiation of the cell wall matrix defines the contact sites in lobed mesophyll cells of Zea mays.

Science.gov (United States)

Giannoutsou, E; Sotiriou, P; Apostolakos, P; Galatis, B

2013-10-01

The morphogenesis of lobed mesophyll cells (MCs) is highly controlled and coupled with intercellular space formation. Cortical microtubule rings define the number and the position of MC isthmi. This work investigated early events of MC morphogenesis, especially the mechanism defining the position of contacts between MCs. The distributions of plasmodesmata, the hemicelluloses callose and (1 → 3,1 → 4)-β-d-glucans (MLGs) and the pectin epitopes recognized by the 2F4, JIM5, JIM7 and LM6 antibodies were studied in the cell walls of Zea mays MCs. Matrix cell wall polysaccharides were immunolocalized in hand-made sections and in sections of material embedded in LR White resin. Callose was also localized using aniline blue in hand-made sections. Plasmodesmata distribution was examined by transmission electron microscopy. Before reorganization of the dispersed cortical microtubules into microtubule rings, particular bands of the longitudinal MC walls, where the MC contacts will form, locally differentiate by selective (1) deposition of callose and the pectin epitopes recognized by the 2F4, LM6, JIM5 and JIM7 antibodies, (2) degradation of MLGs and (3) formation of secondary plasmodesmata clusterings. This cell wall matrix differentiation persists in cell contacts of mature MCs. Simultaneously, the wall bands between those of future cell contacts differentiate with (1) deposition of local cell wall thickenings including cellulose microfibrils, (2) preferential presence of MLGs, (3) absence of callose and (4) transient presence of the pectins identified by the JIM5 and JIM7 antibodies. The wall areas between cell contacts expand determinately to form the cell isthmi and the cell lobes. The morphogenesis of lobed MCs is characterized by the early patterned differentiation of two distinct cell wall subdomains, defining the sites of the future MC contacts and of the future MC isthmi respectively. This patterned cell wall differentiation precedes cortical microtubule

Comments on the variation of spike morphology in selected species of Elytrigia and Elymus (Triticeae

Directory of Open Access Journals (Sweden)

Romuald Kosina

2014-01-01

Full Text Available The structure of spikes of Elytrigia repens, E. intermedia and Elymus caninus was investigated. The number of spikelets per spike reveals the weakest correlations with other characters of the spike. The same concerns some character ratios. The correlations provide information about the segmented structure (metamers of the spike. There is a great difference between matrices of correlation coefficients for E. repens and E. intermedia related to the development and structure of spike. Characters important for the description of the spike were chosen - in five-character set these are among others: length of glume awn in median spikelet, length of lemma awn in the first floret of the median spikelet, number of spikelets per spike. Length of lemma awn and mean length of the rachis segment were recognized as the best discriminants for species. Ordination of forms along axes of canonical variates does not indicate the subunits within E. repens. Intermediate forms between E. repens and Elymus caninus have not been found. Between E. repens and E. intermedia there exists some proximity. Heteromorphic individuals were described by means of cluster analysis. They prove the mobility of the genome in ramets of a single genet.

Second-order asymptotics for quantum hypothesis testing in settings beyond i.i.d.—quantum lattice systems and more

International Nuclear Information System (INIS)

Datta, Nilanjana; Rouzé, Cambyse; Pautrat, Yan

2016-01-01

Quantum Stein’s lemma is a cornerstone of quantum statistics and concerns the problem of correctly identifying a quantum state, given the knowledge that it is one of two specific states (ρ or σ). It was originally derived in the asymptotic i.i.d. setting, in which arbitrarily many (say, n) identical copies of the state (ρ"⊗"n or σ"⊗"n) are considered to be available. In this setting, the lemma states that, for any given upper bound on the probability α_n of erroneously inferring the state to be σ, the probability β_n of erroneously inferring the state to be ρ decays exponentially in n, with the rate of decay converging to the relative entropy of the two states. The second order asymptotics for quantum hypothesis testing, which establishes the speed of convergence of this rate of decay to its limiting value, was derived in the i.i.d. setting independently by Tomamichel and Hayashi, and Li. We extend this result to settings beyond i.i.d. Examples of these include Gibbs states of quantum spin systems (with finite-range, translation-invariant interactions) at high temperatures, and quasi-free states of fermionic lattice gases.

A generalization of the q-(Pfaff)-Saalschutz summation formula is proved. This implies a generalization of the Burge transform, resulting in an additional dimension of the ``Burge tree''. Limiting cases of our summation formula imply the (higher-level) Bailey lemma, provide a new decomposition of the q-multinomial coefficients, and can be used to prove the Lepowsky and Primc formula for the A_1^{(1)} string functions.

Abstract: The article discusses the user perspective and information retrieval in relation to the lemmatisation of specific multi-word lexical units, namely fixed expressions, in the Shona monolingual dictionary, Duramazwi Guru reChiShona. It shows that the decisions arrived at in lemmatising fixed expressions were influenced by a user-driven approach. The article gives a comparative analysis of how fixed expressions were treated in previous Shona dictionaries and how they were subsequently dealt with in Duramazwi Guru reChiShona. Previous dictionaries have grappled with the problem of giving fixed expressions as run-on entries. Against the background of the user perspective, it will be argued that the lemmatisation of fixed expressions in monolingual dictionaries has certain advantages over previously used strategies.

I'm Right and You're and Idiot — Jim Hoggan discusses the toxic state of public discourse and how to clean it up, by changing the communication climate

Science.gov (United States)

Hoggan, J. C.

2016-12-01

Just as the natural environment can be polluted, so too can public discourse. I'm Right and You're an Idiot: The Toxic State of Public Discourse and How to Clean it Up examines the sorry state of today's public square, showing how polluted, polarized conversations discourage people from taking action on critical issues such as climate change, and demonstrating how we can clear the air and become more powerful and effective communicators. The most urgent environmental threat today is not climate change, species extinction or the declining health of oceans. Author Jim Hoggan says the more pressing problem is resistance to change that results from pollution in the public square. A smog of adversarial rhetoric, propaganda and polarization that comes from all sides, is stifling discussion and our ability to solve problems collectively. Hoggan has investigated this troubling state of public dialogue and in his new book he asks leading intellectuals why, despite overwhelming scientific evidence, so little is being done to address today's critical environmental challenges. As chair of the David Suzuki Foundation and founder of one of Canada's most successful PR firms, he is uniquely positioned to probe this question. During Hoggan's 30 years in crisis management he has dealt with food poisonings, labour disputes, multi-million dollar bank fraud, sawmill explosions, even bodies disappearing from funeral homes. He also authored the bestseller Climate Cover-Up, which took a critical look at science propaganda and the widespread echo chamber of media and think tanks that magnifies it. How do we improve public discourse and curb over-the-top advocacy, corrupt conversations and propaganda. How do we counteract polarization and gridlock? Hoggan sought answers from more than 60 outstanding scholars, ranging from a NASA scientist to deep-sea oceanographer. He tapped the brains of cognitive researchers, political pundits, philosophers, moral psychologists, corporate analysts and

Pore Structure and Diagenetic Controls on Relative Permeability: Implications for Enhanced Oil Recovery and CO2 Storage

Science.gov (United States)

Feldman, J.; Dewers, T. A.; Heath, J. E.; Cather, M.; Mozley, P.

2016-12-01

Multiphase flow in clay-bearing sandstones of the Morrow Sandstone governs the efficiency of CO2 storage and enhanced oil recovery at the Farnsworth Unit, Texas. This formation is the target for enhanced oil recovery and injection of one million metric ton of anthropogenically-sourced CO2. The sandstone hosts eight major flow units that exhibit distinct microstructural characteristics due to diagenesis, including: "clean" macro-porosity; quartz overgrowths constricting some pores; ghost grains; intergranular porosity filled by microporous authigenic clay; and feldspar dissolution. We examine the microstructural controls on macroscale (core scale) relative permeability and capillary pressure behavior through: X-ray computed tomography, Robomet.3d, and focused ion beam-scanning electron microscopy imaging of the pore structure of the major flow units of the Morrow Sandstone; relative permeability and capillary pressure in the laboratory using CO2, brine, and oil at reservoir pressure and effective stress conditions. The combined data sets inform links between patterns of diagenesis and multiphase flow. These data support multiphase reservoir simulation and performance assessment by the Southwest Regional Partnership on Carbon Sequestration (SWP). Funding for this project is provided by the U.S. Department of Energy's National Energy Technology Laboratory through the SWP under Award No. DE-FC26-05NT42591.

We develop the generalized Cartan Calculus for the groups and SO(5 , 5). They are the underlying algebraic structures of d = 9 , 7 , 6 exceptional field theory, respectively. These algebraic identities are needed for the "tensor hierarchy" structure in exceptional field theory. The validity of Poincaré lemmas in this new differential geometry is also discussed. Finally we explore some possible extension of the generalized Cartan calculus beyond the exceptional series.

Distribution of some pectic and arabinogalactan protein epitopes during Solanum lycopersicum (L.) adventitious root development.

Science.gov (United States)

Sala, Katarzyna; Malarz, Katarzyna; Barlow, Peter W; Kurczyńska, Ewa U

2017-01-25

The adventitious roots (AR) of plants share the same function as primary and lateral roots (LR), although their development is mainly an adaptive reaction to stress conditions. Regeneration of grafted plants is often accompanied by AR formation thus making the grafting technique a good model for studying AR initiation and development and their means of emergence. Pectins and arabinogalactan proteins (AGP) are helpful markers of particular cellular events, such as programmed cell death (PCD), elongation, proliferation or other differentiation events that accompany AR development. However, little is known about the distribution of pectins and AGPs during AR ontogeny, either in the primordium or stem tissues from which AR arise or their correspondence with these events during LR formation. AR were developed from different stem tissues such as parenchyma, xylem rays and the cambium, depending on the stem age and treatment (grafting versus cutting) of the parental tissue. Immunochemical analysis of the presence of pectic (LM8, LM19, LM20) and AGP (JIM8, JIM13, JIM16) epitopes in AR and AR-associated tissues showed differential, tissue-specific distributions of these epitopes. Two pectic epitopes (LM19, LM20) were developmentally regulated and the occurrence of the LM8 xylogalacturonan epitope in the root cap of the AR differed from other species described so far. AGP epitopes were abundantly present in the cytoplasmic compartments (mainly the tonoplast) and were correlated with the degree of cell vacuolisation. JIM8 and JIM13 epitopes were detected in the more advanced stages of primordium development, whereas the JIM16 epitope was present from the earliest division events of the initial AR cells. The comparison between AR and LR showed quantitative (AGP,) and qualitative (pectins) differences. The chemical compositions of adventitious and lateral root cells show differences that correlate with the different origins of these cells. In AR, developmental changes in the

Directory of Open Access Journals (Sweden)

Filasová Anna

2016-06-01

Full Text Available The H∞ norm approach to virtual actuators design, intended to Takagi-Sugeno fuzzy continuous-time systems, is presented in the paper. Using the second Ljapunov method, the design conditions are formulated in terms of linear matrix inequalities in adapted bounded real lemma structures. Related to the static output controller, and for systems under influence of single actuator faults, the design steps are revealed for a three-tank system plant.

2010-08-01

Full Text Available In this paper we investigate the existence of the periodic solutions of a quasilinear differential equation with piecewise constant argument of generalized type. By using some fixed point theorems and some new analysis technique, sufficient conditions are obtained for the existence and uniqueness of periodic solutions of these systems. A new Gronwall type lemma is proved. Some examples concerning biological models as Lasota-Wazewska, Nicholson's blowflies and logistic models are treated.

Probabilistic metric spaces were introduced by Karl Menger. Alsina, Schweizer and Sklar gave a general definition of probabilistic normed space based on the definition of Menger . We introduce the concept of semi-invariance among the PN spaces. In this paper we will find a sufficient condition for some PN spaces to be semi-invariant. We will show that PN spaces are normal spaces. Urysohn's lemma, and Tietze extension theorem for them are proved.

State-Feedback Control for Fractional-Order Nonlinear Systems Subject to Input Saturation

Directory of Open Access Journals (Sweden)

Junhai Luo

2014-01-01

Full Text Available We give a state-feedback control method for fractional-order nonlinear systems subject to input saturation. First, a sufficient condition is derived for the asymptotical stability of a class of fractional-order nonlinear systems. Then based on Gronwall-Bellman lemma and a sector bounded condition of the saturation function, a linear state-feed back controller is designed. Finally, two simulation examples are presented to show the validity of the proposed method.

Maximum principles for boundary-degenerate second-order linear elliptic differential operators

OpenAIRE

Feehan, Paul M. N.

2012-01-01

We prove weak and strong maximum principles, including a Hopf lemma, for smooth subsolutions to equations defined by linear, second-order, partial differential operators whose principal symbols vanish along a portion of the domain boundary. The boundary regularity property of the smooth subsolutions along this boundary vanishing locus ensures that these maximum principles hold irrespective of the sign of the Fichera function. Boundary conditions need only be prescribed on the complement in th...

Introduction to Stopping Time in Stochastic Finance Theory. Part II

Directory of Open Access Journals (Sweden)

Jaeger Peter

2017-12-01

Full Text Available We start proceeding with the stopping time theory in discrete time with the help of the Mizar system [1], [4]. We prove, that the expression for two stopping times k1 and k2 not always implies a stopping time (k1 + k2 (see Theorem 6 in this paper. If you want to get a stopping time, you have to cut the function e.g. (k1 + k2 ⋂ T (see [2, p. 283 Remark 6.14]. Next we introduce the stopping time in continuous time. We are focused on the intervals [0, r] where r ∈ ℝ. We prove, that for I = [0, r] or I = [0,+∞[ the set {A ⋂ I : A ∈ Borel-Sets} is a σ-algebra of I (see Definition 6 in this paper, and more general given in [3, p.12 1.8e]. The interval I can be considered as a timeline from now to some point in the future. This set is necessary to define our next lemma. We prove the existence of the σ-algebra of the τ -past, where τ is a stopping time (see Definition 11 in this paper and [6, p.187, Definition 9.19]. If τ1 and τ2 are stopping times with τ1 is smaller or equal than τ2 we can prove, that the σ-algebra of the τ1-past is a subset of the σ-algebra of the τ2-past (see Theorem 9 in this paper and [6, p.187 Lemma 9.21]. Suppose, that you want to use Lemma 9.21 with some events, that never occur, see as a comparison the paper [5] and the example for ST(1={+∞} in the Summary. We don’t have the element +1 in our above-mentioned time intervals [0, r[ and [0,+1[. This is only possible if we construct a new σ-algebra on ℝ {−∞,+∞}. This construction is similar to the Borel-Sets and we call this σ-algebra extended Borel sets (see Definition 13 in this paper and [3, p. 21]. It can be proved, that {+∞} is an Element of extended Borel sets (see Theorem 21 in this paper. Now we use the interval [0,+∞] as a basis. We construct a σ-algebra on [0,+∞] similar to the book ([3, p. 12 18e], see Definition 18 in this paper, and call it extended Borel subsets. We prove for stopping times with this given σ-algebra, that

The taktivine immune correction influence on the immune status of an irradiated organism

Low-methylesterified homogalacturonans have been suggested to play a role in the binding and immobilization of Pb in CW. Using root apices of hybrid aspen, a plant with a high phytoremediation potential, as a model, we demonstrated that the in situ distribution pattern of low-methylesterified homogalacturonan, pectin epitope (JIM5-P), reflects the pattern of Pb occurrence. The region which indicated high JIM5-P level corresponded with “Pb accumulation zone”. Moreover, JIM5-P was especially abundant in cell junctions, CWs lining the intercellular spaces and the corners of intercellular spaces indicating the highest accumulation of Pb. Furthermore, JIM5-P and Pb commonly co-localized. The observations indicate that low-methylesterified homogalacturonan is the CW polymer that determines the capacity of CW for Pb sequestration. Our results suggest a promising directions for CW modification for enhancing the efficiency of plant roots in Pb accumulation, an important aspect in the phytoremediation of soils contaminated with trace metals. - Highlights: • Co-localization of low-methylesterified pectins and Pb was analysed in situ. • The pattern of Pb accumulation matched low-methylesterified pectins distribution. • Low-methylesterified pectins and Pb commonly co-localized in cell walls. • Low-methylesterified pectins revealed an important compound in Pb sequestration. • We suggest a new direction in enhancing plant efficiency for phytoremediation. - The distribution of lead in developing tissues of aspen root tips exposed to short-term lead treatment mimics the distribution of low-methylesterified pectin epitope

A Solution Space for a System of Null-State Partial Differential Equations: Part 2

Science.gov (United States)

Flores, Steven M.; Kleban, Peter

2015-01-01

This article is the second of four that completely and rigorously characterize a solution space for a homogeneous system of 2 N + 3 linear partial differential equations in 2 N variables that arises in conformal field theory (CFT) and multiple Schramm-Löwner evolution (SLE). The system comprises 2 N null-state equations and three conformal Ward identities which govern CFT correlation functions of 2 N one-leg boundary operators. In the first article (Flores and Kleban, Commun Math Phys, arXiv:1212.2301, 2012), we use methods of analysis and linear algebra to prove that dim , with C N the Nth Catalan number. The analysis of that article is complete except for the proof of a lemma that it invokes. The purpose of this article is to provide that proof. The lemma states that if every interval among ( x 2, x 3), ( x 3, x 4),…,( x 2 N-1, x 2 N ) is a two-leg interval of (defined in Flores and Kleban, Commun Math Phys, arXiv:1212.2301, 2012), then F vanishes. Proving this lemma by contradiction, we show that the existence of such a nonzero function implies the existence of a non-vanishing CFT two-point function involving primary operators with different conformal weights, an impossibility. This proof (which is rigorous in spite of our occasional reference to CFT) involves two different types of estimates, those that give the asymptotic behavior of F as the length of one interval vanishes, and those that give this behavior as the lengths of two intervals vanish simultaneously. We derive these estimates by using Green functions to rewrite certain null-state PDEs as integral equations, combining other null-state PDEs to obtain Schauder interior estimates, and then repeatedly integrating the integral equations with these estimates until we obtain optimal bounds. Estimates in which two interval lengths vanish simultaneously divide into two cases: two adjacent intervals and two non-adjacent intervals. The analysis of the latter case is similar to that for one vanishing

The BQP-hardness of approximating the Jones polynomial

International Nuclear Information System (INIS)

Aharonov, Dorit; Arad, Itai

2011-01-01

A celebrated important result due to Freedman et al (2002 Commun. Math. Phys. 227 605-22) states that providing additive approximations of the Jones polynomial at the kth root of unity, for constant k=5 and k≥7, is BQP-hard. Together with the algorithmic results of Aharonov et al (2005) and Freedman et al (2002 Commun. Math. Phys. 227 587-603), this gives perhaps the most natural BQP-complete problem known today and motivates further study of the topic. In this paper, we focus on the universality proof; we extend the result of Freedman et al (2002) to ks that grow polynomially with the number of strands and crossings in the link, thus extending the BQP-hardness of Jones polynomial approximations to all values to which the AJL algorithm applies (Aharonov et al 2005), proving that for all those values, the problems are BQP-complete. As a side benefit, we derive a fairly elementary proof of the Freedman et al density result, without referring to advanced results from Lie algebra representation theory, making this important result accessible to a wider audience in the computer science research community. We make use of two general lemmas we prove, the bridge lemma and the decoupling lemma, which provide tools for establishing the density of subgroups in SU(n). Those tools seem to be of independent interest in more general contexts of proving the quantum universality. Our result also implies a completely classical statement, that the multiplicative approximations of the Jones polynomial, at exactly the same values, are P-hard, via a recent result due to Kuperberg (2009 arXiv:0908.0512). Since the first publication of those results in their preliminary form (Aharonov and Arad 2006 arXiv:quant-ph/0605181), the methods we present here have been used in several other contexts (Aharonov and Arad 2007 arXiv:quant-ph/0702008; Peter and Stephen 2008 Quantum Inf.

Do we need statistics when we have linguistics?

Directory of Open Access Journals (Sweden)

Cantos Gómez Pascual

2002-01-01

Full Text Available Statistics is known to be a quantitative approach to research. However, most of the research done in the fields of language and linguistics is of a different kind, namely qualitative. Succinctly, qualitative analysis differs from quantitative analysis is that in the former no attempt is made to assign frequencies, percentages and the like, to the linguistic features found or identified in the data. In quantitative research, linguistic features are classified and counted, and even more complex statistical models are constructed in order to explain these observed facts. In qualitative research, however, we use the data only for identifying and describing features of language usage and for providing real occurrences/examples of particular phenomena. In this paper, we shall try to show how quantitative methods and statistical techniques can supplement qualitative analyses of language. We shall attempt to present some mathematical and statistical properties of natural languages, and introduce some of the quantitative methods which are of the most value in working empirically with texts and corpora, illustrating the various issues with numerous examples and moving from the most basic descriptive techniques (frequency counts and percentages to decision-taking techniques (chi-square and z-score and to more sophisticated statistical language models (Type-Token/Lemma-Token/Lemma-Type formulae, cluster analysis and discriminant function analysis.

Full Text Available The development of an inflected form generator for Afrikaans In this article the development of an inflected form generator for Afrikaans is described. Two requirements are set for this inflected form generator, viz. to generate only one specific inflected form of a lemma and to generate all possible inflected forms of a lemma. The decision to use machine learning instead of the more traditional rule-based approach in the development of this core-technology is explained and a brief overview of the development of LIA, a lemmatiser for Afrikaans, is given. Experiments are done with three different methods and it is shown that the most effective way of developing an inflected form generator for Afrikaans is by training different classifiers for each affix. Therefore a classifier is trained to generate a plural form, one to generate the diminutive, one to generate the plural of diminutive, et cetera. The final inflected form generator for Afrikaans (AIL-3 reaches an average accuracy of 86,37% on the training data and 86,88% on a small amount of new data. It is indicated that, with the help of a preprocessing module, AIL-3 meets the requirements that were set for an Afrikaans inflected form generator. Finally suggestions are made on how to improve the accuracy of AIL-3.

2015-08-01

The xylanase inhibitor TAXI-III has been proven to delay Fusarium head blight (FHB) symptoms caused by Fusarium graminearum in transgenic durum wheat plants. To elucidate the molecular mechanism underlying the capacity of the TAXI-III transgenic plants to limit FHB symptoms, we treated wheat tissues with the xylanase FGSG_03624, hitherto shown to induce cell death and hydrogen peroxide accumulation. Experiments performed on lemmas of flowering wheat spikes and wheat cell suspension cultures demonstrated that pre-incubation of xylanase FGSG_03624 with TAXI-III significantly decreased cell death. Most interestingly, a reduced cell death relative to control non-transgenic plants was also obtained by treating, with the same xylanase, lemmas of TAXI-III transgenic plants. Molecular modelling studies predicted an interaction between the TAXI-III residue H395 and residues E122 and E214 belonging to the active site of xylanase FGSG_03624. These results provide, for the first time, clear indications in vitro and in planta that a xylanase inhibitor can prevent the necrotic activity of a xylanase, and suggest that the reduced FHB symptoms on transgenic TAXI-III plants may be a result not only of the direct inhibition of xylanase activity secreted by the pathogen, but also of the capacity of TAXI-III to avoid host cell death. © 2014 BSPP AND JOHN WILEY & SONS LTD.

Yet another proof of Hawking and Ellis's Lemma 8.5.5

The fact that the null generators of a future Cauchy horizon are past-complete was first proved by Hawking and Ellis (1973 The Large Scale Structure of Spacetime (Cambridge: Cambridge University Press)). Then, Budzyński, Kondracki and Królak outlined a proof free from the error found in the original one (2000 New properties of Cauchy and event horizons arXiv:gr-qc/0011033). Now, Minguzzi has published his version of the proof (2014 J. Math. Phys. 55 082503), patching a previously unnoticed hole in the preceding two. I am not aware of any flaws in that last proof, but it is quite difficult. In this note, I present a simpler one. (note)

We specify an “archetype” version of the Davis-Putnam-Logemann-Loveland algorithm through the THEORY of recursive functions based on a well-founded relation, and prove it to be correct.Within the same framework, and by resorting to the Zorn lemma, we develop a straightforward proof of the compactness theorem.

Homotopical Dynamics IV: Hopf invariants and hamiltonian flows

In a non-compact context the first natural step in the search for periodic orbits of a hamiltonian flow is to detect bounded ones. In this paper we show that, in a non-compact setting, certain algebraic topological constraints imposed to a gradient flow of the hamiltonian function $f$ imply the existence of bounded orbits for the hamiltonian flow of $f$. Once the existence of bounded orbits is established, under favorable circumstances, application of the $C^{1}$-closing lemma leads to period...

Beyond Epistemological Deficits: Dynamic explanations of engineering students' difficulties with mathematical sense-making

Science.gov (United States)

Gupta, Ayush; Elby, Andrew

2011-12-01

Researchers have argued against deficit-based explanations of students' difficulties with mathematical sense-making, pointing instead to factors such as epistemology. Students' beliefs about knowledge and learning can hinder the activation and integration of productive knowledge they have. Such explanations, however, risk falling into a 'deficit trap'-substituting a concepts/skills deficit with an epistemological one. Our interview-based case study of a freshman engineering major, 'Jim,' explains his difficulty solving a physics problem (on hydrostatic pressure) in terms of his epistemology, but avoids a deficit trap by modeling the dynamics of his epistemological stabilities and shifts in terms of fine-grained cognitive elements that include the seeds of epistemological expertise. Specifically, during a problem-solving episode in the interview, Jim reaches and sticks with an incorrect answer that violates common sense. We show that Jim has all the mathematical skills and physics knowledge he would need to resolve the contradiction. We argue that his difficulty doing so stems in part from his epistemological views that (i) physics equations are much more trustworthy than everyday reasoning, and (ii) physics equations do not express meaning that tractably connects to common sense. For these reasons, he does not view reconciling between common sense and formalism as either necessary or plausible to accomplish. But Jim's in-the-moment shift to a more sophisticated epistemological stance highlights the seeds of epistemological expertise that were present all along: he does see common sense as connected to formalism (though not always tractably so), and in some circumstances, this connection is both salient and valued.

Arabinogalactan proteins in plants

Directory of Open Access Journals (Sweden)

Ewa Szczuka

2013-04-01

Full Text Available AGPs (arabinogalactan-proteins are the major constituent of arabic gum and have been used as emulsifiers and stabilizing agents. They are also one of the most abundant and heterogeneous class forming a large family of proteoglycans that sculpt the surface not only of plant but also of all eukaryotic cells. Undoubtedly, AGPs appear in numerous biological processes, playing diverse functions. Despite their abundance in nature and industrial utility, the in vivofunction(s of AGPs still remains unclear or even unknown. AGPs are commonly distributed in different plant organs and probably participate in all aspects of plant growth and development including reproduction (e.g. they are present in the stigma including stigma exudates, and in transmitting tissues in styles, pollen grains, and pollen tubes. The functions and evident involvement of AGPs in sexual plant reproduction in a few plant species as Actinidia deliciosa (A.Chev. C.F.Liang & A.R.Ferguson, Amaranthus hypochondriacus L., Catharanthus roseus (L. G.Don, Lolium perenneL. and Larix deciduaMill. are known from literature. The localization of two kinds of AGP epitopes, recognized by the JIM8 and JIM13 mAbs, in anatomically different ovules revealed some differences in spatial localization of these epitopes in ovules of monocots Galanthus nivalis L. and Galtonia candicans (Baker Decne. and dicots like Oenothera species and Sinapis albaL. A detailed study of the localization of AGPs in egg cells, zygotes, including the zygote division stage, and in two-celled proembryos in Nicotiana tabacumL. prompts consideration of the necessity of their presence in the very early steps of ontogenesis. The selective labeling obtained with AGP mAbs JIM8, JIM13, MAC207, and LM2 during Arabidopsis thaliana(L. Heynh. development suggests that some AGPs can be regarded as molecular markers for gametophytic cell differentiation. Moreover, the results show evident differences in the distribution of specific AGP

Problematizing the concept ‘epistemological access’: A review of literature

Directory of Open Access Journals (Sweden)

Lucinda du Plooy

2014-07-01

Full Text Available This paper provides a review of literature which aims at problematizing the concept ‘epistemological access”, a fairly under-researched topic in South African education. Morrow’s distinction between formal access (institutional access and epistemological access (access to the goods distributed by the institution is used as a conceptual framework. We argue that the meaning of the concept ‘epistemological access’ as Morrow intended was borne out of a particular political need that arose in higher education; the need to democratize access to higher education. The dearth of literature on the concept “epistemological access” and its meaning for access to basic education, especially foundation phase schooling, therefore warranted this literature review.

A coupled FE and scaled boundary FE-approach for the earthquake response analysis of arch dam-reservoir-foundation system

International Nuclear Information System (INIS)

Wang Yi; Lin Gao; Hu Zhiqiang

2010-01-01

For efficient and accurate modelling of arch dam-reservoir-foundation system a coupled Finite Element method (FEM) and Scaled Boundary Finite Element method (SBFEM) is developed. Both the dam-foundation interaction and the dam-reservoir interaction including the effect of reservoir boundary absorption are taken into account. The arch dam is modelled by FEM, while the reservoir domain and the unbounded foundation are modelled by SBFEM. In order to make comparison with the results available in the literature, the Morrow Point arch dam is selected for numerical analysis. The analyses are carried out in the frequency domain, and then the time-domain response of the dam-reservoir-foundation system is obtained by Inverse Fourier Transform.

Characterization of cyclic deformation behaviour of tempered and quenched 42CrMoS4 at single step and variable amplitude loading

International Nuclear Information System (INIS)

Schelp, M.; Eifler, D.

2000-01-01

Cyclic single steps tests were performed on tempered and quenched specimens of the steel 42CrMoS4. Strain, temperature and electrical resistance measurements yielded an empirical prediction of fatigue life according to Coffin, Manson and Morrow. All measured values are based on physical processes and therefore show a strong interaction. A new testing procedure was developed permitting hysteresis measurements to be used for the characterization and description of fatigue behaviour under variable amplitude loading. The basic idea is to combine fatigue tests with any kind of load spectrum with single step tests. This offers the possibility to apply lifetime prediction methods normally used for single step tests for those with random or service loading. (orig.)

Islamic movement and human rights: Pertubuhan Jamaah Islah Malaysia’s involvement in the “Abolish Internal Security Act Movement,” 2000-2012

Full Text Available Human rights has been acknowledged as one of the essential characteristics of good governance. Abuse of human rights is strongly associated with bad governance, which is believed by many to be a serious impediment to development and sustainable growth. Despite the active participations of Islamic movements in many parts of the political world, very little is known of their involvement in advocating human rights issues as part of their struggle for power. Nevertheless, as an Islamic movement and an Islamic revivalism actor in Malaysia, Pertubuhan Jamaah Islah Malaysia (JIM has shown otherwise. JIM has resembled a different attitude towards the issue of human rights that they believe as an integrated and pertinent composition of good governance. By scrutinising their political activities and discourse since 2000, it becomes clear that JIM has been actively engaged in good governance and human rights issues, especially those that relate to the political rights of citizens through its involvement in the Abolish Internal Security Act (ISA Movement (Gerakan Mansuhkan ISA. This paper examines JIM’s involvement in human rights issues with a special focus on its active and leading role in calling for the abolishment of the Internal Security Act (ISA.

Phytolith analysis for differentiating between foxtail millet (Setaria italica) and green foxtail (Setaria viridis).

Science.gov (United States)

Foxtail millet (Setaria italica) is one of the oldest domesticated cereal crops in Eurasia, but identifying foxtail millets, especially in charred grains, and differentiating it from its wild ancestor, green foxtail (Setaria viridis), in the archaeobotanical remains, is still problematic. Phytolithic analysis provides a meaningful method for identifying this important crop. In this paper, the silicon structure patterns in the glumes, lemmas, and paleas from inflorescence bracts in 16 modern plants of foxtail millet and green foxtail from China and Europe are examined using light microscopy with phase-contrast and a microscopic interferometer. Our research shows that the silicon structure of ΩIII from upper lemmas and paleas in foxtail millet and green foxtail can be correspondingly divided into two groups. The size of ΩIII type phytolith of foxtail millet is bigger than that from green foxtail. Discriminant function analysis reveals that 78.4% of data on foxtail millet and 76.9% of data on green foxtail are correctly classified. This means certain morphotypes of phytoliths are relatively reliable tools for distinguishing foxtail millet from green foxtail. Our results also revealed that the husk phytolith morphologies of foxtail millets from China and Eastern Europe are markedly different from those from Western Europe. Our research gives a meaningful method of separating foxtail millet and green foxtail. The implications of these findings for understanding the history of foxtail millet domestication and cultivation in ancient civilizations are significant.

Krisztin, Tibor; Wu, Jianhong

1998-01-01

This book contains recent results about the global dynamics defined by a class of delay differential equations which model basic feedback mechanisms and arise in a variety of applications such as neural networks. The authors describe in detail the geometric structure of a fundamental invariant set, which in special cases is the global attractor, and the asymptotic behavior of solution curves on it. The approach makes use of advanced tools which in recent years have been developed for the investigation of infinite-dimensional dynamical systems: local invariant manifolds and inclination lemmas f

Feedback control for distributed heat transfer mechanisms in direct-contact membrane distillation system

KAUST Repository

Eleiwi, Fadi; N'Doye, Ibrahima; Laleg-Kirati, Taous-Meriem

2015-01-01

In this paper, the problem of stabilization and production rate reference tracking for a Direct-Contact Membrane Distillation (DCMD) system is addressed. Sufficient conditions for the asymptotic and exponential stabilization for DCMD system are presented using the Gronwall-Bellman lemma and Linear Matrix Inequalities (LMIs) approaches, respectively. A nonlinear observer is then proposed to estimate the temperature distribution among the DCMD domain. This contributes to propose a reference production rate control design for the DCMD process via observer-based output control approach. Finally, numerical simulations are given to show the effectiveness of the proposed methods.

Full Text Available In this note we present equations that uniquely determine the maximum possible imaginary value of the closed loop eigenvalues in an LQ-optimal system, irrespective of how the state weight matrix is chosen, provided a real symmetric solution of the algebraic Riccati equation exists. In addition, the corresponding state weight matrix and the solution to the algebraic Riccati equation are derived for a class of linear systems. A fundamental lemma for the existence of a real symmetric solution to the algebraic Riccati equation is derived for this class of linear systems.

Some sufficient conditions for Hamiltonian property in terms of ...

[1, D], or Wf (G) ≥ f (1). 2 n2 + [f(2) − 3. 2 f(1)]n − 2[f(2) − f(1)] for a monotonically decreasing function f(x) on x ∈ [1, D], then G is Hamiltonian, unless G ∼= K∗ n or K2∨3K1. Proof. Assume that G is not a Hamiltonian graph with degree sequence (d1,d2,...,dn), where d1 ≤ d2 ≤ ··· ≤ dn and n ≥ 3. By Lemma 1, there is a ...

Hyper-lattice algebraic model for data warehousing

CERN Document Server

Sen, Soumya; Chaki, Nabendu

2016-01-01

This book presents Hyper-lattice, a new algebraic model for partially ordered sets, and an alternative to lattice. The authors analyze some of the shortcomings of conventional lattice structure and propose a novel algebraic structure in the form of Hyper-lattice to overcome problems with lattice. They establish how Hyper-lattice supports dynamic insertion of elements in a partial order set with a partial hierarchy between the set members. The authors present the characteristics and the different properties, showing how propositions and lemmas formalize Hyper-lattice as a new algebraic structure.

Rational homotopy theory and differential forms

CERN Document Server

Griffiths, Phillip

2013-01-01

This completely revised and corrected version of the well-known Florence notes circulated by the authors together with E. Friedlander examines basic topology, emphasizing homotopy theory. Included is a discussion of Postnikov towers and rational homotopy theory. This is then followed by an in-depth look at differential forms and de Tham's theorem on simplicial complexes. In addition, Sullivan's results on computing the rational homotopy type from forms is presented.  New to the Second Edition: *Fully-revised appendices including an expanded discussion of the Hirsch lemma*Presentation of a natu

A family of isospectral Euler–Bernoulli beams

International Nuclear Information System (INIS)

Gladwell, Graham M L; Morassi, Antonino

2010-01-01

In this paper we consider the class of Euler–Bernoulli beams such that the product between the bending stiffness and the linear mass density is constant. Under the assumption that the end conditions are any combination of pinned and sliding, we obtain closed-form expressions for beams isospectral to a given one. The analysis is based on the fact that this special class of beams is, in a certain sense, equivalent to a string, and uses a Darboux lemma after reduction of the string equation to Sturm–Liouville canonical form

Adaptive observer based synchronization of a class of uncertain chaotic systems

International Nuclear Information System (INIS)

Bowong, S.; Yamapi, R.

2005-05-01

This study addresses the adaptive synchronization of a class of uncertain chaotic systems in the drive-response framework. For a class of uncertain chaotic systems with unknown parameters and external disturbances, a robust adaptive observer based response system is constructed to synchronize the uncertain chaotic system. Lyapunov stability theory and Barbalat lemma ensure the global synchronization between the drive and response systems even if Lipschitz constants on function matrices and bounds on uncertainties are unknown. Numerical simulation of the Genesio-Tesi system verifies the effectiveness of the proposed method. (author)

Topological rings

CERN Document Server

Warner, S

1993-01-01

This text brings the reader to the frontiers of current research in topological rings. The exercises illustrate many results and theorems while a comprehensive bibliography is also included. The book is aimed at those readers acquainted with some very basic point-set topology and algebra, as normally presented in semester courses at the beginning graduate level or even at the advanced undergraduate level. Familiarity with Hausdorff, metric, compact and locally compact spaces and basic properties of continuous functions, also with groups, rings, fields, vector spaces and modules, and with Zorn''s Lemma, is also expected.

Feedback control for distributed heat transfer mechanisms in direct-contact membrane distillation system

KAUST Repository

Eleiwi, Fadi

2015-09-21

In this paper, the problem of stabilization and production rate reference tracking for a Direct-Contact Membrane Distillation (DCMD) system is addressed. Sufficient conditions for the asymptotic and exponential stabilization for DCMD system are presented using the Gronwall-Bellman lemma and Linear Matrix Inequalities (LMIs) approaches, respectively. A nonlinear observer is then proposed to estimate the temperature distribution among the DCMD domain. This contributes to propose a reference production rate control design for the DCMD process via observer-based output control approach. Finally, numerical simulations are given to show the effectiveness of the proposed methods.

Synonymy in the Translation Equivalent Paradigms of a Standard Translation Dictionary

Directory of Open Access Journals (Sweden)

Phillip Adriaan Louw

2012-09-01

Full Text Available The norm in current canonical translation dictionaries with Afrikaans and English as the treated language pair is an undiscriminated grouping of partially synonymous translation equivalents. These are separated by commas as sole markers of synonymy. Lexicographers should reject this practice and embrace the view that absolute synonyms are just as rare as absolute equivalents. In most cases members of a target language synonym paradigm will be partial synonyms demanding some form of contextual guidance in order to distinguish them from other equivalents in the paradigm.

This article will focus on the motivation for the indication of partial target language synonymy. Two particular motivations will be discussed, as well as ways in which equivalent discrimination can be implemented.

The first motivation arises from a group of problematic phenomena that effect contextual divergence between the source and target language. Stylistic and register divergence should necessitate contextual guidance. Lexicographical labels are the most frequently used discriminators, but in South African dictionaries they are applied too sparingly and inconsistently. Other possible discriminators will also be discussed.

The most problematic motivation for the indication of partial synonymy is however different equivalents for various usages of a lemma. Ways in which equivalent discrimination can be implemented in these cases, will be discussed in detail.

Lastly, it will be shown that without a new, more effective method of indicating and ordering target language synonyms, none of the major changes that are pleaded for, will bear fruit.

Keywords: absolute synonymy; contextual guidance; equivalent discrimination; lexicographic labels; partial synonymy; polysemy; senses; standard translation dictionary; synonymy; target language synonyms; target language synonym paradigm; translation equivalent paradigm; usages of the lemma
