  5. Obituary: John Daniel Kraus, 1910-2004 (United States)

    Kraus, John D., Jr.; Marhefka, Ronald J.


    John Daniel Kraus, 94, of Delaware, Ohio, director of the Ohio State University "Big Ear" Radio Observatory, physicist, inventor, and environmentalist died 18 July 2004 at his home in Delaware, Ohio. He was born on 28 June 1910 in Ann Arbor, Michigan. He received a Bachelor of Science in 1930, a Master of Science in 1931, and a PhD in physics in 1933 (at 23 years of age), all from the University of Michigan, Ann Arbor. During the 1930s at Michigan, he was involved in physics projects, antenna consulting, and in atomic-particle-accelerator research using the University of Michigan's premier cyclotron. Throughout the late 1920s and the 1930s, John was an avid radio amateur with call sign W8JK. He was back on the air in the 1970s. In 2001 the amateur radio magazine CQ named him to the inaugural class of its Amateur Radio Hall of Fame. He developed many widely used innovative antennas. The "8JK closely spaced array" and the "corner reflector" were among his early designs. Edwin H. Armstrong wrote John in July 1941 indicating in part, "I have read with interest your article in the Proceedings of the Institute on the corner reflector...Please let me congratulate you on a very fine piece of work." Perhaps John's most famous invention, and a product of his intuitive reasoning process, is the helical antenna, widely used in space communications, on global positioning satellites, and for other applications. During World War II, John was in Washington, DC as a civilian scientist with the U.S. Navy responsible for "degaussing" the electromagnetic fields of steel ships to make them safe from magnetic mines. He also worked on radar countermeasures at Harvard University's Radio Research Laboratory. He received the U.S. Navy Meritorious Civilian Service Award for his war work. In 1946 he took a faculty position at Ohio State University, becoming professor in 1949, and retiring in 1980 as McDougal Professor Emeritus of Electrical Engineering and Astronomy. Even so, he never retired

  7. Occurrence of substance P-like immunoreactive nerve fibers in Krause corpuscles of the dog's tongue. (United States)

    Ichikawa, H; Nishikawa, S; Wakisaka, S; Matsuo, S; Takano, Y; Akai, M


    Substance P-like immunoreactive (SPLI) nerve fibers were demonstrated in the Krause corpuscles of the dog's tongue using the indirect immunofluorescence method and cholinesterase histochemistry. SPLI nerve fibers were often in contact with Krause end bulbs and occasionally entered them. From this result it was suggested that substance P might be involved in sensory mechanism of the Krause apparatus.

  8. The Ordovician ostracodes established by Aurel Krause, Part I

    R. Schallreuter


    Full Text Available The lack of a revision of the ostracodes described by Aurel Krause at the end of the 19th century from glacial erratic boulders from Berlin and the Mark Brandenburg (Northern Germany has led to taxonomic confusion in the corresponding literature of the 20th century. To attain stability in names, some of Krause's ostracode species have been revised based on the types stored in the Museum für Naturkunde Berlin, namely Primitia plana, P. plana tuberculata, P. intermedia, P. globifera, Entomis sigma antiquata, Bollia v-scripta, B. granulosa, B. duplex, Strepula lineata, Isochilina canaliculata, Beyrichia dissecta, B. mamillosa, B. signata, and B. bidens. Most species have up to four younger synonyms among species described later from outcrops or borings in Baltoscandia or glacial erratic boulders of Northern Germany and Sweden. Three of Krause's species, which have been considered as nomina dubia by Jaanusson are in fact valid species. Some of Krause's species or of their synonyms are type species. doi:10.1002/mmng.201000015

    Full Text Available The revision of ostracodes originally established by Aurel Krause is continued and finished with the description of the following species: Primitia distans, P. elongata, P. cincta, P. excavata, P. papillata, P. plicata, P. schmidtii, Strepula limbata, S. simplex, Entomis obliqua, E. plicata, E. sigma, E. sigma ornata, E. simplex, E. trilobata, Beyrichia erratica, B. erratica granulosa, B. erratica acuta, B. harpa, and B. marchica lata. Three of these species are younger primary homonyms. For Beyrichia erratica granulosa Krause, 1891 a respective decision of the ICZN according to art. 23.9.5 is presently unnecessary, because it has an older synonym (Beyrichia grewingkii Bock, 1867, and Primitia excavata Krause, 1892 has a younger synonym (Laccochilina paucigranosa Jaanusson, 1957. The third homonym, Beyrichia marchica lata Krause, 1891, is considered as a nomen protectum. Entomis sigma ornata, and E. plicata are presently considered as nomina dubia. Since the type material of the three species P. distans, E. sigma, and E. simplex is apparently lost, neotypes are designated. doi:10.1002/mmng.201300007

    Dirk Rose


    Full Text Available This essay focuses on the medial transgression from the written word to action in the polemic writings of Karl Kraus. The manifestation of transgression in his polemical wri­tings should be seen as a consequent mode which characterizes his concept of polemics, finally as a permanent excess of its own medial as well as conceptual requirements. In the second part, this essay discusses ethical and/or political problems that result from those modes of transgression, particularly in Kraus’ attitude towards the First World War and the Nazi regime.

  11. The noisy Hegselmann-Krause model for opinion dynamics (United States)

    Pineda, Miguel; Toral, Raúl; Hernández-García, Emilio


    In the model for continuous opinion dynamics introduced by Hegselmann and Krause, each individual moves to the average opinion of all individuals within an area of confidence. In this work we study the effects of noise in this system. With certain probability, individuals are given the opportunity to change spontaneously their opinion to another one selected randomly inside the opinion space with different rules. If the random jump does not occur, individuals interact through the Hegselmann-Krause's rule. We analyze two cases, one where individuals can carry out opinion random jumps inside the whole opinion space, and other where they are allowed to perform jumps just inside a small interval centered around the current opinion. We found that these opinion random jumps change the model behavior inducing interesting phenomena. Using pattern formation techniques, we obtain approximate analytical results for critical conditions of opinion cluster formation. Finally, we compare the results of this work with the noisy version of the Deffuant et al. model [G. Deffuant, D. Neu, F. Amblard, G. Weisbuch, Adv. Compl. Syst. 3, 87 (2000)] for continuous-opinion dynamics.

  13. Shakespearean Thoughts as Statutes. Law and Literature in Karl Kraus Pensieri shakespeariani come leggi dello stato. Letteratura e diritto in Karl Kraus

    Directory of Open Access Journals (Sweden)

    Irene Fantappie


    Full Text Available It is not possible to understand Karl Kraus, claims Walter Benjamin, without assuming that in the oeuvre of the Viennese writer "everything takes place in the sphere of law". In Kraus’s thought legal issues are strongly related to literature and language. His concept of law stems from a higher ideal of ‘justice’; justice is based on language and language has a strong ideal and prescriptive value. Through the use of quotation Kraus charges literature and journalism with betraying language, while on the other hand he charges law with betraying justice. This essay aims at demonstrating trough an interdisciplinary approach that Kraus did not only involve law issues in his literary writings, he also invested some literary works – especially Shakespeare’s plays – with a legal value. In Kraus’s thought Shakespeare is a symbol of consubstantiality between reality and literature, and an 'encyclopedia' providing eternally valid categories. As an ideal paradigm for the interpretation of reality, Shakespeare is the utopian background of Kraus’s reflection on language and justice, bearing witness to the indissolubility, in Kraus’s thought, of literature and law.   È impossibile comprendere alcunché di Karl Kraus, afferma Walter Benjamin, se non si capisce che nell’opera del grande scrittore viennese «tutto ha luogo nella sfera del diritto». In Kraus l’analisi delle questioni giuridiche è inscindibile dalla riflessione sulla letteratura e sul linguaggio. La disamina del diritto muove da un più alto ideale di giustizia fondato sulla lingua, e specularmente il linguaggio possiede una forte valenza ideale e prescrittivo-normativa. Attraverso l’uso della citazione Kraus mette sotto accusa letteratura e giornalismo in nome di un più alto ideale di lingua, mentre nei suoi scritti letterari mette sotto accusa il sistema del diritto in nome di un più alto ideale di giustizia. Scopo del presente saggio è dimostrare, utilizzando un

  14. Fedor Krause: the first systematic use of X-rays in neurosurgery. (United States)

    Elhadi, Ali M; Kalb, Samuel; Martirosyan, Nikolay L; Agrawal, Abhishek; Preul, Mark C


    Within a few months of Wilhelm Conrad Röntgen's discovery of x-rays in 1895, Fedor Krause acquired an x-ray apparatus and began to use it in his daily interactions with patients and for diagnosis. He was the first neurosurgeon to use x-rays methodically and systematically. In 1908 Krause published the first volume of text on neurosurgery, Chirurgie des Gehirns und Rückenmarks (Surgery of the Brain and Spinal Cord), which was translated into English in 1909. The second volume followed in 1911. This was the first published multivolume text totally devoted to neurosurgery. Although Krause excelled in and promoted neurosurgery, he believed that surgeons should excel at general surgery. Importantly, Krause was inclined to adopt technology that he believed could be helpful in surgery. His 1908 text was the first neurosurgical text to contain a specific chapter on x-rays ("Radiographie") that showed roentgenograms of neurosurgical procedures and pathology. After the revolutionary discovery of x-rays by Röntgen, many prominent neurosurgeons seemed pessimistic about the use of x-rays for anything more than trauma or fractures. Krause immediately seized on its use to guide and monitor ventricular drainage and especially for the diagnosis of tumors of the skull base. The x-ray images contained in Krause's "Radiographie" chapter provide a seminal view into the adoption of new technology and the development of neurosurgical technique and are part of neurosurgery's heritage.

  15. Model and simulation of Krause model in dynamic open network (United States)

    Zhu, Meixia; Xie, Guangqiang


    The construction of the concept of evolution is an effective way to reveal the formation of group consensus. This study is based on the modeling paradigm of the HK model (Hegsekmann-Krause). This paper analyzes the evolution of multi - agent opinion in dynamic open networks with member mobility. The results of the simulation show that when the number of agents is constant, the interval distribution of the initial distribution will affect the number of the final view, The greater the distribution of opinions, the more the number of views formed eventually; The trust threshold has a decisive effect on the number of views, and there is a negative correlation between the trust threshold and the number of opinions clusters. The higher the connectivity of the initial activity group, the more easily the subjective opinion in the evolution of opinion to achieve rapid convergence. The more open the network is more conducive to the unity of view, increase and reduce the number of agents will not affect the consistency of the group effect, but not conducive to stability.

  16. Continued-fraction representation of the Kraus map for non-Markovian reservoir damping (United States)

    van Wonderen, A. J.; Suttorp, L. G.


    Quantum dissipation is studied for a discrete system that linearly interacts with a reservoir of harmonic oscillators at thermal equilibrium. Initial correlations between system and reservoir are assumed to be absent. The dissipative dynamics as determined by the unitary evolution of system and reservoir is described by a Kraus map consisting of an infinite number of matrices. For all Laplace-transformed Kraus matrices exact solutions are constructed in terms of continued fractions that depend on the pair correlation functions of the reservoir. By performing factorizations in the Kraus map a perturbation theory is set up that conserves in arbitrary perturbative order both positivity and probability of the density matrix. The latter is determined by an integral equation for a bitemporal matrix and a finite hierarchy for Kraus matrices. In the lowest perturbative order this hierarchy reduces to one equation for one Kraus matrix. Its solution is given by a continued fraction of a much simpler structure as compared to the non-perturbative case. In the lowest perturbative order our non-Markovian evolution equations are applied to the damped Jaynes–Cummings model. From the solution for the atomic density matrix it is found that the atom may remain in the state of maximum entropy for a significant time span that depends on the initial energy of the radiation field.

  17. Optimization search effort over the control landscapes for open quantum systems with Kraus-map evolution

    International Nuclear Information System (INIS)

    Oza, Anand; Pechen, Alexander; Beltrani, Vincent; Moore, Katharine; Rabitz, Herschel; Dominy, Jason


    A quantum control landscape is defined as the expectation value of a target observable Θ as a function of the control variables. In this work, control landscapes for open quantum systems governed by Kraus map evolution are analyzed. Kraus maps are used as the controls transforming an initial density matrix ρ i into a final density matrix to maximize the expectation value of the observable Θ. The absence of suboptimal local maxima for the relevant control landscapes is numerically illustrated. The dependence of the optimization search effort is analyzed in terms of the dimension of the system N, the initial state ρ i and the target observable Θ. It is found that if the number of nonzero eigenvalues in ρ i remains constant, the search effort does not exhibit any significant dependence on N. If ρ i has no zero eigenvalues, then the computational complexity and the required search effort rise with N. The dimension of the top manifold (i.e., the set of Kraus operators that maximizes the objective) is found to positively correlate with the optimization search efficiency. Under the assumption of full controllability, incoherent control modeled by Kraus maps is found to be more efficient in reaching the same value of the objective than coherent control modeled by unitary maps. Numerical simulations are also performed for control landscapes with linear constraints on the available Kraus maps, and suboptimal maxima are not revealed for these landscapes

  18. Kraus Operators for a Pair of Interacting Qubits: a Case Study (United States)

    Arsenijević, M.; Jeknić-Dugić, J.; Dugić, M.


    The Kraus form of the completely positive dynamical maps is appealing from the mathematical and the point of the diverse applications of the open quantum systems theory. Unfortunately, the Kraus operators are poorly known for the two-qubit processes. In this paper, we derive the Kraus operators for a pair of interacting qubits, while the strength of the interaction is arbitrary. One of the qubits is subjected to the x-projection spin measurement. The obtained results are applied to calculate the dynamics of the entanglement in the qubits system. We obtain the loss of the correlations in the finite time interval; the stronger the inter-qubit interaction, the longer lasting entanglement in the system.

  2. Ultrastructural relationships between the receptor nerve fiber and surrounding lamellae in Krause end-bulbs. (United States)

    Spassova, I


    The ultrastructural relationship between the receptor nerve fiber and the surrounding lamellae in Krause end-bulbs was discussed. Many sites of specialized junctions of symmetrical or asymmetrical type along the receptor nerve fiber and the surrounding lamellae were found. In addition, in close vicinity to them, spine-like digitations of the receptor nerve fiber, filled mainly with small clear vesicles, were observed. Mitochondrion-like cholinesterase-positive structures bulging in some cytoplasmic lamellae were also found. It is suggested that a functional link might exist between the specialized junctions, digitations and mitochrondrion-like structures in the transformation of external mechanical stimuli into nerve impulses.

  4. [Our experience with the Krause method in the Clínica y Maternidad Conchita]. (United States)

    Benavides de Anda, L


    The author reports on his experience with the Krause method of pregnancy termination at the "Conchita" Maternity Clinic in Mexico during a period of 13 years, from 1955 to 1968. The following indications are accepted as legitimate and justify use of this method: dead retained ovum, hydatidiform mole, fetal death, and such complications in pregnancy as isoimmunization to the Rh factor, diabetes mellitus, gravidic toxemia, chronic hypertension. 149 patients were studied, of whom 9 had hydatidiform mole, 29 had induced delivery, and 111 had retained dead ovum. The technique and stages of the procedure are described in detail and the results are summarized in 4 tables. The technique is described as simple and requiring few instruments. Results are considered satisfactory, although the method involves some serious dangers. Brief reference is made to other methods of interrupting pregnancy, such as dilatation and curettage, hysterectomy, the injection of hypertonic solution into the uterine cavity and the perfusion of intravenous oxytoxin.

  5. Dynamical phase transitions in Hegselmann-Krause model of opinion dynamics and consensus (United States)

    Slanina, F.


    The dynamics of the model of agents with limited confidence introduced by Hegselmann and Krause exhibits multiple well-separated regimes characterised by the number of distinct clusters in the stationary state. We present indications that there are genuine dynamical phase transitions between these regimes. The main indicator is the divergence of the average evolution time required to reach the stationary state. The slowdown close to the transition is connected with the emergence of the groups of mediator agents which are very small but have decisive role in the process of social convergence. More detailed study shows that the histogram of the evolution times is composed of several peaks. These peaks are unambiguously interpreted as corresponding to mediator groups consisting of one, two, three etc. agents. Detailed study reveals that each transition possesses also an internal fine structure.

  7. Noisy Hegselmann-Krause Systems: Phase Transition and the 2 R-Conjecture (United States)

    Wang, Chu; Li, Qianxiao; E, Weinan; Chazelle, Bernard


    The classic Hegselmann-Krause ( HK) model for opinion dynamics consists of a set of agents on the real line, each one instructed to move, at every time step, to the mass center of the agents within a fixed distance R. In this work, we investigate the effects of noise in the continuous-time version of the model as described by its mean-field Fokker-Planck equation. In the presence of a finite number of agents, the system exhibits a phase transition from order to disorder as the noise increases. We introduce an order parameter to track the phase transition and resolve the corresponding phase diagram. The system undergoes a phase transition for small R but none for larger R. Based on the stability analysis of the mean-field equation, we derive the existence of a forbidden zone for the disordered phase to emerge. We also provide a theoretical explanation for the well-known 2 R conjecture, which states that, for a random initial distribution in a fixed interval, the final configuration consists of clusters separated by a distance of roughly 2 R. Our theoretical analysis confirms previous simulations and predicts properties of the noisy HK model in higher dimension.

  10. Opinion dynamics of modified Hegselmann-Krause model in a group-based population with heterogeneous bounded confidence (United States)

    Fu, Guiyuan; Zhang, Weidong; Li, Zhijun


    Continuous opinion dynamics in a group-based population with heterogeneous bounded confidences is considered in this paper. A slightly modified Hegselmann-Krause model is proposed, and agents are classified into three categories: open-minded-, moderate-minded-, and closed-minded-agents, while the whole population is divided into three subgroups accordingly. We study how agents of each category and the population size can affect opinion dynamics. It is observed that the number of final opinion clusters is dominated by the closed-minded agents; open-minded agents cannot contribute to forming opinion consensus and the existence of open-minded agents may diversify the final opinions instead; for the fixed population size and proportion of closed-minded agents, the relative size of the largest final opinion cluster varies along concave-parabola-like curve as the proportion of open-minded agents increases, and there is a tipping point when the number of open-minded agents is almost equal to that of moderate-minded agents; for the fixed proportion of the three categories in the population, as the population size becomes larger, the number of final opinion clusters will reach a plateau. Some of the results are different from the previous studies.

Besides that, the interaction study of the nanoparticles solution with Pb2+ ions was also studied. The results, shows that the present reduction system (aqueous extract of the plant leaves) successfully reduced gold (III) ions to gold metals as shown by new peak at 544 nm in spectrophotometry analysis. The average nanopartiles size was 96 nm based on Particles Size Analyzer (PSA) result. The stability study revealed that the nanoparticles solution was not stable in the persence of Pb(OAc)2 at high concentration. The nanoparticles were effective enough toward E. coli as shown by inhibition zone that indicates the degree of sensitivity of bacteria to nanoparticles.

    Full Text Available In der 2010 veröffentlichten kommunikationswissenschaftlich ausgerichteten Studie geht es um eine quantitative Beschreibung des Nutzungsverhaltens und der Nutzungsmotive computerspielender Frauen. Melanie Krause argumentiert konsequent innerhalb der fachlichen Grenzen der neueren Mediennutzungsforschung. Wirklich neu ist der von ihr unternommene Versuch einer Spielerinnentypologisierung, indem sie auf der Basis der erhobenen Daten zum Nutzungsverhalten und zu Nutzungsmotiven der Spielerinnen vier Cluster gebildet hat. Diese werden mit vier Spielerinnentypen identifiziert, die allerdings hochgradig normativ besetzt sind. Aus der Perspektive der kritischen Gender Studies wäre eine Reflexion und Diskussion der in die Spielerinnentypologie eingeflossenen normativen Voraussetzungen wünschenswert.

    Full Text Available The MeOH extract of Dracaena viridiflora was found to display significant cytotoxicity against some cancer cell lines. Systematic phytochemical investigation of this extract led to the isolation and structure elucidation of ten secondary metabolites including five spirostane (1-5 and one furostane (6 steroidal saponins. Furthermore, some acetylated spirostane analogues and three previously unreported derivatives with the 22,26-epoxycholesta-5,22-diene skeleton (15-17 were prepared from trillin (1, prosapogenin A of dioscin (2 and dioscin (4 by reaction with ZnCl 2/Ac 2O. Among the isolated and semisynthetic compounds, dioscin showed the most potent cytotoxicity against A549, Jurkat and Skov-3 cells with IC 50 values of 0.42, 1.70 and 1.90 µg/mL, respectively. It was noteworthy that acetylation of the bioactive compounds led to semisynthetic derivatives which unfortunately did not present any activity. This is the first report on the phytochemical and pharmacological investigation of Dracaena viridiflora.

  17. Opinion Dynamics of Social-Similarity-Based Hegselmann–Krause Model

    Directory of Open Access Journals (Sweden)

    Xi Chen


    Full Text Available The existing opinion dynamics models mainly concentrate on the impact of opinions on other opinions and ignore the effect of the social similarity between individuals. Social similarity between an individual and their neighbors will also affect their opinions in real life. Therefore, an opinion evolution model considering social similarity (social-similarity-based HK model, SSHK model for short is introduced in this paper. Social similarity is calculated using individual properties and is used to measure the social relationship between individuals. By considering the joint effect of confidence bounds and social similarity in this model, the role of neighbors’ selection is changed significantly in the process of the evolution of opinions. Numerical results demonstrate that the new model can not only obtain the salient features of the opinion result, namely, fragmentation, polarization, and consensus, but also achieve consensus more easily under the appropriate similarity threshold. In addition, the improved model with heterogeneous and homogeneous confidence bounds and similarity thresholds are also discussed. We found that the improved heterogeneous SSHK model could acquire opinion consensus results more easily than the homogeneous SSHK model and the classical models when the confidence bound was related to the similarity threshold. This finding provides a new way of thinking and a theoretical basis for the guidance of public opinion in real life.

    This work describes phytochemical analysis of an Araceae species Dracontium spruceanum (Schott) G.Zhu, which occurs in Amazon region and is popularly used against snakebite and treatment of some diseases. The solvent partitions and chromatographic fractionations of extract afforded sitosterol (I), stigmasterol (II), 3-β-hydroxycolest-5-en-7-one (III), p-hydroxybenzaldehyde (IV), p-hydroxybenzoic acid (V), acyl-glycosyl sitosterol (VI), acyl-glycosyl-7-oxo-sitosterol (VII), sitosteryl-glycoside (VIII), sucrose (IX). The polar fractions were acetylated before the purification and the isolation through chromatographic techniques yielded a mixture of peracetylated carbohydrates: 2,3,4,6-tetra-O-acetyl-1-ethyl-glucose (X), which was identified by spectroscopic analysis [GC-MS, 13 C NMR and 1 H NMR].

  1. A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Duck Creek, Madison, Tipton, and Hamilton counties, Indiana (United States)

    Crawford, Charles G.; Wilber, William G.; Peters, James G.


    The Indiana State Board of Health is developing a State water-quality plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Duck Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards defined for two critical hydrologic conditions, summer and winter low flows. The major point-source waste load affecting Duck Creek is the Elwood wastewater-treatment facility. Natural streamflow during the low flow is zero, so no benefit from dilution is provided. Natural reaeration at the low-flow condition (approximately 3 cubic feet per second), also low, is estimated to be less than 1 per day (base e at 20 Celsius). Consequently, the wasteload assimilative capacity of the stream is low. Effluent ammonia-nitrogen concentrations, projected by the Indiana State Board of Health, will result in stream ammonia-nitrogen concentrations that exceed the State ammonia-nitrogen toxicity standards (2.5 milligrams per liter from April to October and 4.0 milligrams per liter from November through March). The projected effluent ammonia-nitrogen load will also result in the present Indiana stream dissolved-oxygen standard (5.0 milligrams per liter) not being met. Benthic-oxygen demand may also affect stream water quality. During the summer low-flow, a benthic-oxygen demand of only 0.6 gram per square meter per day would utilize all the streams 's available assimilative capacity. (USGS)

  10. Well-posedness of the limiting equation of a noisy consensus model in opinion dynamics (United States)

    Chazelle, Bernard; Jiu, Quansen; Li, Qianxiao; Wang, Chu


    This paper establishes the global well-posedness of the nonlinear Fokker-Planck equation for a noisy version of the Hegselmann-Krause model. The equation captures the mean-field behavior of a classic multiagent system for opinion dynamics. We prove the global existence, uniqueness, nonnegativity and regularity of the weak solution. We also exhibit a global stability condition, which delineates a forbidden region for consensus formation. This is the first nonlinear stability result derived for the Hegselmann-Krause model.

  11. Operator-sum representation for bosonic Gaussian channels

    International Nuclear Information System (INIS)

    Ivan, J. Solomon; Sabapathy, Krishna Kumar; Simon, R.


    Operator-sum or Kraus representations for single-mode bosonic Gaussian channels are developed, and several of their consequences explored. The fact that the two-mode metaplectic operators acting as unitary purification of these channels do not, in their canonical form, mix the position and momentum variables is exploited to present a procedure which applies uniformly to all families in the Holevo classification. In this procedure the Kraus operators of every quantum-limited Gaussian channel can be simply read off from the matrix elements of a corresponding metaplectic operator. Kraus operators are employed to bring out, in the Fock basis, the manner in which the antilinear, unphysical matrix transposition map when accompanied by injection of a threshold classical noise becomes a physical channel, denoted D(κ) in the Holevo classification. The matrix transposition channels D(κ), D(κ -1 ) turn out to be a dual pair in the sense that their Kraus operators are related by the adjoint operation. The amplifier channel with amplification factor κ and the beam-splitter channel with attenuation factor κ -1 turn out to be mutually dual in the same sense. The action of the quantum-limited attenuator and amplifier channels as simply scaling maps on suitable quasiprobabilities in phase space is examined in the Kraus picture. Consideration of cumulants is used to examine the issue of fixed points. The semigroup property of the amplifier and attenuator families leads in both cases to a Zeno-like effect arising as a consequence of interrupted evolution. In the cases of entanglement-breaking channels a description in terms of rank 1 Kraus operators is shown to emerge quite simply. In contradistinction, it is shown that there is not even one finite rank operator in the entire linear span of Kraus operators of the quantum-limited amplifier or attenuator families, an assertion far stronger than the statement that these are not entanglement breaking channels. A characterization of

Further, in connection with corresponding rigorous formulas for the field from a circular, helical antenna with a uniformly progressing current wave of constant amplitude the present formulas may be used for an investigation of the magnitude of the error introduced in Kraus......' approximate calculation of the field from a circular, helical antenna by replacing this antenna with an ``equivalent'' square helix. This investigation is carried out by means of a numerical example. The investigation shows that Kraus' approximate method of calculation yields results in fair agreement...

    Full Text Available The identification of small colon lesions is one of the major problems in laparoscopic colonic resection.Research objective: to develop a technique of visualization of small tumors of a colon by preoperative endoscopic marking of a tumor.Materials and methods. In one day prior to operation to the patient after bowel preparation the colonoscopy is carried out. In the planned point near tumor on antimesentery edge the submucous infiltration of marking solution (Micky Sharpz blue tattoo pigment, UK is made. The volume of entered solution of 1–3 ml. In only 5 months of use of a technique preoperative marking to 14 patients with small (the size of 1–3 cm malignant tumors of the left colon is performed.Results. The tattoo mark was well visualized by during operation at 13 of 14 patients. In all cases we recorded no complications. Time of operation with preoperative marking averaged 108 min, that is significantly less in comparison with average time of operation with an intra-operative colonoscopy – 155 min (р < 0.001.Conclusions. The first experience of preoperative endoscopic marking of non palpable small tumors of a colon is encouraging. Performance of a technique wasn't accompanied by complications and allowed to reduce significantly time of operation and to simplify conditions of performance of operation.

  9. Stress concentration factors for pressurized elliptic crossbores in blocks

    International Nuclear Information System (INIS)

    Badr, Elie A.


    Intersecting bore geometries are used in a number of industrial applications including heavy-walled pressure vessels containing oil holes for lubrication, ports for valves and fluid ends of reciprocating pumps. The bore intersection location is a stress concentration point where the maximum hoop stress can be many times the fluid pressure in the bores. Intersecting circular holes in heavy-walled cylinders and rectangular blocks have been extensively investigated. Specifically, stress/pressure concentration curves for intersecting circular bores in rectangular blocks were presented by Sorem et al. [Sorem JR, Shadley JR, Tipton SM. Design curves for maximum stresses in blocks containing pressurized bore intersections. ASME J Mech Des 1990; 113: 427-31.]. However, stress/pressure concentrations due to intersecting elliptic bores have not been broadly investigated. With the availability of computer numerical control (CNC) machinery, bores with elliptic crosssection can be produced with relative ease. In this paper, hoop stress concentration ratios are developed for elliptic crossbores in rectangular blocks. Results indicate that introducing elliptic crossbores, rather than circular ones, significantly reduces the hoop stress concentration factor at the crossbore intersection. Also, the presence of intersecting crossbores has a major effect on the fatigue life of pressure vessels [Badr EA, Sorem JR, Jr Tipton SM. Evaluation of the autofrettage effect on fatigue lives of steel blocks with crossbores using a statistical and a strain-based method. ASTM J Test Eval 2000; 28: 181-8.] and the reduction of hoop stress concentration is expected to enhance the fatigue life of pressure vessels containing crossbores

  10. Trapping Dust to Form Planets (United States)

    Kohler, Susanna


    Growing a planet from a dust grain is hard work! A new study explores how vortices in protoplanetary disks can assist this process.When Dust Growth FailsTop: ALMA image of the protoplanetary disk of V1247 Orionis, with different emission components labeled. Bottom: Synthetic image constructed from the best-fit model. [Kraus et al. 2017]Gradual accretion onto a seed particle seems like a reasonable way to grow a planet from a grain of dust; after all, planetary embryos orbit within dusty protoplanetary disks, which provides them with plenty of fuel to accrete so they can grow. Theres a challenge to this picture, though: the radial drift problem.The radial drift problem acknowledges that, as growing dust grains orbit within the disk, the drag force on them continues to grow as well. For large enough dust grains perhaps around 1 millimeter the drag force will cause the grains orbits to decay, and the particles drift into the star before they are able to grow into planetesimals and planets.A Close-Up Look with ALMASo how do we overcome the radial drift problem in order to form planets? A commonly proposed mechanism is dust trapping, in which long-lived vortices in the disk trap the dust particles, preventing them from falling inwards. This allows the particles to persist for millions of years long enough to grow beyond the radial drift barrier.Observationally, these dust-trapping vortices should have signatures: we would expect to see, at millimeter wavelengths, specific bright, asymmetric structures where the trapping occurs in protoplanetary disks. Such disk structures have been difficult to spot with past instrumentation, but the Atacama Large Millimeter/submillimeter Array (ALMA) has made some new observations of the disk V1247 Orionis that might be just what were looking for.Schematic of the authors model for the disk of V1247 Orionis.

    Since the 1960’ties the influence of the thermal stratification in hot water tanks on the thermal performance of solar heating systems has been studied intensively. It was found, that the thermal performance of a solar heating system is increasing for increasing thermal stratification in the hot...... water tank. The temperature of the storage water heated by the solar collector loop usually varies strongly during the day. In order to reach a good thermal stratification in the tank, different types of pipes, plates, diffusers and other devices have been investigated in the past (e.g. Loehrke, 1979...... plates inside the pipes (Davidson, 1992) or openings in form of balls (e.g. Leibfried, 2000) or flaps (e.g. described in Krause, 2001) have entered the market during the recent years.

  12. Resolving the Birth of High-Mass Binary Stars (United States)

    Kohler, Susanna


    New observations may help us to learn more about the birth of high-mass star systems. For the first time, scientists have imaged a very young, high-mass binary system and resolved the individual disks that surround each star and the binary.Massive MultiplesIts unusually common for high-mass stars to be discovered in multiple-star systems. More than 80% of all O-type stars which have masses greater than 16 times that of the Sun are in close multiple systems, compared with a multiplicity fraction of only 20% for stars of 3 solar masses, for instance.Reconstructed VLTI observations of the two components of the high-mass binary IRAS17216-3801. [Adapted from Kraus et al. 2017]Why do more massive stars preferentially form in multiple-star systems? Many different models of high-mass star formation have been invoked to explain this observation, but before we can better understand the process, we need better observations. In particular, past observations have placed few constraints on the architecture and disk structure of early high-mass stars.Conveniently, a team of scientists led by Stefan Kraus (University of Exeter) may have found exactly what we need: a high-mass protobinary that is still in the process of forming. Using ESOs Very Large Telescope Interferometer (VLTI), Kraus and collaborators have captured the first observations of a very young, high-mass binary system in which the circumbinary disk and the two circumstellar dust disks could all be spatially resolved.Clues from Resolved DisksThe VLTI near-infrared observations reveal that IRAS17216-3801, originally thought to be a single high-mass star, is instead a close binary separated by only 170 AU. Its two components are both surrounded by disks from which the protostars are actively accreting mass, and both of these circumstellar disks are strongly misaligned with respect to the separation vector of the binary. This confirms that the system is very young, as tidal forces havent yet had time to align the disks

  14. Neurophysiological Evidence That Musical Training Influences the Recruitment of Right Hemispheric Homologues for Speech Perception

    Directory of Open Access Journals (Sweden)

    McNeel Gordon Jantzen


    Full Text Available Musicians have a more accurate temporal and tonal representation of auditory stimuli than their non-musician counterparts (Kraus & Chandrasekaran, 2010; Parbery-Clark, Skoe, & Kraus, 2009; Zendel & Alain, 2008; Musacchia, Sams, Skoe, & Kraus, 2007. Musicians who are adept at the production and perception of music are also more sensitive to key acoustic features of speech such as voice onset timing and pitch. Together, these data suggest that musical training may enhance the processing of acoustic information for speech sounds. In the current study, we sought to provide neural evidence that musicians process speech and music in a similar way. We hypothesized that for musicians, right hemisphere areas traditionally associated with music are also engaged for the processing of speech sounds. In contrast we predicted that in non-musicians processing of speech sounds would be localized to traditional left hemisphere language areas. Speech stimuli differing in voice onset time was presented using a dichotic listening paradigm. Subjects either indicated aural location for a specified speech sound or identified a specific speech sound from a directed aural location. Musical training effects and organization of acoustic features were reflected by activity in source generators of the P50. This included greater activation of right middle temporal gyrus (MTG and superior temporal gyrus (STG in musicians. The findings demonstrate recruitment of right hemisphere in musicians for discriminating speech sounds and a putative broadening of their language network. Musicians appear to have an increased sensitivity to acoustic features and enhanced selective attention to temporal features of speech that is facilitated by musical training and supported, in part, by right hemisphere homologues of established speech processing regions of the brain.

    Baptista Afonso, Ana Carolina


    El crecimiento demográfico, la explotación de los recursos naturales, el cambio climático y otros factores están poniendo al mundo en una trayectoria de desarrollo que no es sostenible (KPMG, 2012). La conciencia ambiental de los consumidores se ha intensificado en gran medida en las últimas décadas (Kalafatis et al., 1999). En consecuencia, los consumidores estan más preocupados con el medio ambiente y progresivamente han ido cambiando sus hábitos diarios y patrones de compra (Krause, 1993)....

  17. Boltzmann factor and Hawking radiation

    International Nuclear Information System (INIS)

    Ryskin, Gregory


    Hawking radiation has thermal spectrum corresponding to the temperature T H =(8πM) −1 , where M is the mass (energy) of the black hole. Corrections to the Hawking radiation spectrum were discovered by Kraus and Wilczek (1995) and Parikh and Wilczek (2000). Here I show that these corrections follow directly from the basic principles of thermodynamics and statistical mechanics. In essence, it is the Boltzmann factor that ought to be corrected; corrections to the Hawking (or any other) radiation spectrum then follow necessarily

  4. Max Dvořák and Austrian Denkmalpflege at War

    Directory of Open Access Journals (Sweden)

    Jonathan Blower


    Full Text Available As was often the case with Vienna School art historians, Max Dvořák (1874-1921 contributed a significant amount to the theory and practice of monument preservation. This paper considers his reactions to the precarious situation of artistic heritage during and after the first world war, which he conceived as a conflict between spiritual and material values. In writings that betray a less than objective patriotism, Italy emerges as Dvořák’s principal antagonist, whilst critical voices in Austria – that of Karl Kraus in particular – undermined his position by calling for an end to the so-called monument cult.

    In this thesis, we explore both total syntheses and methodologies of several aromatic heterocyclic molecules. Extensions of the Kraus indole synthesis toward 2-substituted and 2,3-disubstituted indoles, as well as biologically attractive indolo[2,1-a]isoquinolines are described. Recent renewable efforts directed to commodity maleic acid and the first reported furan-based ionic liquids are described. Our total synthesis of mRNA aptamer ligand PDC-Gly, and its dye coupled forms, plus aminoglycoside dye coupled ligands used in molecular imaging, are described.

  6. The tunneling radiation of a black hole with a f( R) global monopole under generalized uncertainty principle (United States)

    Chen, Lingshen; Cheng, Hongbo


    The Parikh-Kraus-Wilczeck tunneling radiation of black hole involving a f( R) global monopole is considered based on the generalized uncertainty principle. The influences from global monopole, f( R) gravity and the corrections to the uncertainty appear in the expression of black hole entropy difference. It is found that the global monopole and the revision of general relativity both hinder the black hole from emitting the photons. The two parts as corrections to the uncertainty make the entropy difference of this kind of black hole larger or smaller respectively.

    Saleem, Rabia; Sharif, M.


    We check the consistency of the entropy of Bardeen and Ayón Beato-García-Bronnikov black holes with the entropy of particular conformal field theory via Cardy-Verlinde formula. We also compute the first-order semiclassical corrections of this formula due to self-gravitational effects by modifying pure extensive and Casimir energy in the context of Keski-Vakkuri, Kraus and Wilczek analysis. It is concluded that the correction term remains positive for both black holes, which leads to the violation of the holographic bound


    Energy Technology Data Exchange (ETDEWEB)



    PET is uniquely capable of providing information on biochemical transformations in the living human body. Although most of the studies of monoamine oxidase (MAO) have focused on measurements in the brain, the role of peripheral MAO as a phase 1 enzyme for the metabolism of drugs and xenobiotics is gaining attention (Strolin Benedetti and Tipton, 1998; Castagnoli et al., 1997.). MAO is well suited for this role because its concentration in organs such as kidneys, liver and digestive organs is high sometimes exceeding that in the brain. Knowledge of the distribution of the MAO subtypes within different organs and different cells is important in determining which substrates (and which drugs and xenobiotics) have access to which MAO subtypes. The highly variable subtype distribution with different species makes human studies even more important. In addition, the deleterious side effects of combining MAO inhibitors with other drugs and with foodstuffs makes it important to know the MAO inhibitory potency of different drugs both in the brain and in peripheral organs (Ulus et al., 2000). Clearly PET can play a role in answering these questions, in drug research and development and in discovering some of the factors which contribute to the highly variable MAO levels in different individuals.

  10. Unit physics performance of a mix model in Eulerian fluid computations

    Energy Technology Data Exchange (ETDEWEB)

    Vold, Erik [Los Alamos National Laboratory; Douglass, Rod [Los Alamos National Laboratory


    In this report, we evaluate the performance of a K-L drag-buoyancy mix model, described in a reference study by Dimonte-Tipton [1] hereafter denoted as [D-T]. The model was implemented in an Eulerian multi-material AMR code, and the results are discussed here for a series of unit physics tests. The tests were chosen to calibrate the model coefficients against empirical data, principally from RT (Rayleigh-Taylor) and RM (Richtmyer-Meshkov) experiments, and the present results are compared to experiments and to results reported in [D-T]. Results show the Eulerian implementation of the mix model agrees well with expectations for test problems in which there is no convective flow of the mass averaged fluid, i.e., in RT mix or in the decay of homogeneous isotropic turbulence (HIT). In RM shock-driven mix, the mix layer moves through the Eulerian computational grid, and there are differences with the previous results computed in a Lagrange frame [D-T]. The differences are attributed to the mass averaged fluid motion and examined in detail. Shock and re-shock mix are not well matched simultaneously. Results are also presented and discussed regarding model sensitivity to coefficient values and to initial conditions (IC), grid convergence, and the generation of atomically mixed volume fractions.

  13. Naval Petroleum Reserves in California site environmental report for calendar year 1989

    Energy Technology Data Exchange (ETDEWEB)


    This summary for Naval Petroleum Reserves in California (NPRC) is divided into NPR-1 and NPR-2. Monitoring efforts at NPR-1 include handling and disposal of oilfield wastes; environmental preactivity surveys for the protection of endangered species and archaeological resources; inspections of topsoil stockpiling; monitoring of revegetated sites; surveillance of production facilities for hydrocarbons and oxides of nitrogen (NO{sub x}) emissions; monitoring of oil spill prevention and cleanup; and monitoring of wastewater injection. No major compliance issues existed for NPR-1 during 1989. Oil spills are recorded, reviewed for corrective action, and reported. Environmental preactivity surveys for proposed projects which may disturb or contaminate the land are conducted to prevent damage to the federally protected San Joaquin kit fox, blunt-nosed leopard lizard, Tipton kangaroo rat and the giant kangaroo rat. Projects are adjusted or relocated as necessary to avoid impact to dens, burrows, or flat-bottomed drainages. A major revegetation program was accomplished in 1989 for erosion control enhancement of endangered species habitat. The main compliance issue on NPR-2 was oil and produced water discharges into drainages by lessees. An additional compliance issue on NPR-2 is surface refuse from past oilfield operations. 17 refs.

  15. Oil shale resources in the Eocene Green River Formation, Greater Green River Basin, Wyoming, Colorado, and Utah (United States)



    The U.S. Geological Survey (USGS) recently completed a comprehensive assessment of in-place oil in oil shales in the Eocene Green River in the Greater Green River Basin, Wyoming, Colorado, and Utah. This CD-ROM includes reports, data, and an ArcGIS project describing the assessment. A database was compiled that includes about 47,000 Fischer assays from 186 core holes and 240 rotary drill holes. Most of the oil yield data were analyzed by the former U.S. Bureau of Mines oil shale laboratory in Laramie, Wyoming, and some analyses were made by private laboratories. Location data for 971 Wyoming oil-shale drill holes are listed in a spreadsheet and included in the CD-ROM. Total in-place resources for the three assessed units in the Green River Formation are: (1) Tipton Shale Member, 362,816 million barrels of oil (MMBO), (2) Wilkins Peak Member, 704,991 MMBO, and (3) LaClede Bed of the Laney Member, 377,184 MMBO, for a total of 1.44 trillion barrels of oil in place. This compares with estimated in-place resources for the Piceance Basin of Colorado of 1.53 trillion barrels and estimated in-place resources for the Uinta Basin of Utah and Colorado of 1.32 trillion barrels.

    Roxana Acosta


    Full Text Available A redescription of the genus Phalacropsylla Rothschild is provided. Six species are recognized: Phalacropsylla allos Wagner, P. hamata Tipton and Mendez, P. morlani Eads and Campos, P. nivalis Barrera and Traub, P. oregonensis Lewis and Maser, and P. paradisea Rothschild. Phalacropsylla hamata is designated herein as a junior synonym of P. paradisea. The distribution of P. paradisea is more extensive than previously thought, extending from Arizona through southern Colorado, into New Mexico, Texas, and northern Mexico (State of Nuevo León. It is the least host-specific of all species of Phalacropsylla, occurring on 13 different host species including cricetid, heteromyid, murid, and sciurid rodents and several carnivores, although it most commonly occurs on Neotoma albigula Hartley. The range of P. oregonensis is expanded from eastern Oregon to southeastern Idaho. Numerous records are documented for the most common and ubiquitous species, P. allos, which is found in British Columbia, central to northern California, Idaho, Montana, Colorado, Nevada, Utah, Wyoming, Arizona, and New Mexico. Neotoma cinerea Ord is the principal host of P. allos. Phalacropsylla allos is a winter flea west of the Rocky Mountains, but it has been reported in warmer months of the year on the eastern slopes of the Rocky Mountains in Larimer County, Colorado. A distribution map and key are provided for all species in the genus Phalacropsylla.

  18. Critical discussion on the "observed" water balances of five sub-basins in the Everest region (United States)

    Chevallier, P.; Eeckman, J.; Nepal, S.; Delclaux, F.; Wagnon, P.; Brun, F.; Koirala, D.


    The hydrometeorological components of five Dudh Koshi River sub-basins on the Nepalese side of the Mount Everest have been monitored during four hydrological years (2013-2017), with altitudes ranging from 2000 m to Everest top, areas between 4.65 and 1207 km², and proportions of glaciated areas between nil and 45%. This data set is completed with glacier mass balance observations. The analysis of the observed data and the resulting water balances show large uncertainties of different types: aleatory, epistemic or semantic, following the classification proposed by Beven (2016). The discussion is illustrated using results from two modeling approaches, physical (ISBA, Noilhan and Planton, 1996) and conceptual (J2000, Krause, 2001), as well as large scale glacier mass balances obtained by the way of a recent remote sensing processing method.

  19. Smooth manifold structure for extreme channels (United States)

    Iten, Raban; Colbeck, Roger


    A quantum channel from a system A of dimension dA to a system B of dimension dB is a completely positive trace-preserving map from complex dA × dA to dB × dB matrices, and the set of all such maps with Kraus rank r has the structure of a smooth manifold. We describe this set in two ways. First, as a quotient space of (a subset of) the rdB × dA dimensional Stiefel manifold. Second, as the set of all Choi-states of a fixed rank r. These two descriptions are topologically equivalent. This allows us to show that the set of all Choi-states corresponding to extreme channels from system A to system B of a fixed Kraus rank r is a smooth submanifold of dimension 2 r dAdB-dA2-r2 of the set of all Choi-states of rank r. As an application, we derive a lower bound on the number of parameters required for a quantum circuit topology to be able to approximate all extreme channels from A to B arbitrarily well.

  2. Unravelling the Mystery of Massive Star Birth - All Stars are Born the Same Way (United States)


    Astronomers have obtained the first image of a dusty disc closely encircling a massive baby star, providing direct evidence that massive stars form in the same way as their smaller brethren. This discovery, made thanks to a combination of ESO's telescopes, is described in an article in this week's issue of Nature. "Our observations show a disc surrounding an embryonic young, massive star, which is now fully formed," says Stefan Kraus, who led the study. "One can say that the baby is about to hatch!" The team of astronomers looked at an object known by the cryptic name of IRAS 13481-6124. About twenty times the mass of our Sun and five times its radius, the young central star, which is still surrounded by its pre-natal cocoon, is located in the constellation of Centaurus, about 10 000 light-years away. From archival images obtained by the NASA Spitzer Space Telescope as well as from observations done with the APEX 12-metre submillimetre telescope, astronomers discovered the presence of a jet. "Such jets are commonly observed around young low-mass stars and generally indicate the presence of a disc," says Kraus. Circumstellar discs are an essential ingredient in the formation process of low-mass stars such as our Sun. However, it is not known whether such discs are also present during the formation of stars more massive than about ten solar masses, where the strong light emitted might prevent mass falling onto the star. For instance, it has been proposed that massive stars might form when smaller stars merge. In order to discover and understand the properties of this disc, astronomers employed ESO's Very Large Telescope Interferometer (VLTI). By combining light from three of the VLTI's 1.8-metre Auxiliary Telescopes with the AMBER instrument, this facility allows astronomers to see details equivalent to those a telescope with a mirror of 85 metres in diameter would see. The resulting resolution is about 2.4 milliarcseconds, which is equivalent to picking out the head

  3. Collection of short papers on Beaver Creek watershed studies in West Tennessee, 1989-94 (United States)

    Doyle, W. Harry.; Baker, Eva G.


    In 1989, the U.S. Geological Survey began a scientific investigation to evaluate the effect of agricultural activities on water quality and the effectiveness of agricultural best management practices in the Beaver Creek watershed, West Tennessee. The project is being conducted jointly with other Federal, State, county agencies, the farming community, and academic institutions, in support of the U.S. Department of Agriculture's Hydrologic Unit Area program. The Beaver Creek project has evolved into a long-term watershed assessment and monitoring program. In 1991, a grant was received to develop and evaluate sampling strategies for higher order streams. During the summer of 1992, a reconnaissance of water-quality conditions for the shallow aquifers in Shelby, Tipton, Fayette, and Haywood Counties was conducted and included 89 domestic wells in the Beaver Creek watershed. Results from this effort lead to the development of a 1-year program to evaluate cause- and-effect relations that can explain the observed water-quality conditions for the shallow aquifers in the watershed. In 1992 the USGS, in cooperation with the Soil Conservation Service and the Shelby County Soil Conservation District, began an evaluation of in-stream processes and in-stream resource-management systems. In 1993, a biomonitoring program was established in the watershed. This collection of eight articles and abstracts was originally published in the American Water Resources Association National Symposium on Water Quality Proceedings for the national conference held in Chicago in 1994 and describes what has been learned in the study to date.

  4. A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for the Mississinewa River, Grant County, Indiana (United States)

    Wilber, William G.; Crawford, Charles G.; Peters, James G.


    A digital model calibrated to conditions in the Mississinewa River, Grant County, IN was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards defined for two critical hydrologic conditions, summer and winter low flows. The hydrology of the Mississinewa River downstream from Gas City is controlled primarily by two factors; low slopes, typical of the Tipton Till Plain, and a 10-foot dam at river mile 35.9, in Marion. All point-source waste loads affecting the modeled segment of the Mississinewa River are in the four incorporated municipalities of Fairmount, Jonesboro, Gas City, and Marion, in a primarily agricultural area. Model simulations indicate that algal photosynthesis and nitrification are the most significant factors affecting the dissolved-oxygen concentration in the Mississinewa River during summer low flows. Natural reaeration without photosynthesis, is not sufficient to maintain an average dissolved-oxygen concentration of at least 5 milligrams per liter in the stream, the State 's water-quality standard. Projected carbonaceous and nitrogenous biochemical-oxygen demand loads, from the Indiana State Board of Health, for Owens, Illinois, Inc., and the Gas City and Marion wastewater-treatment facility will result in violations of the instream dissolved-oxygen standard. Fairmount and Jonesboro, because of their distance from the Mississinewa, do not significantly affect the water quality of the modeled segment. The model also indicates that, during winter low flows, ammonia toxicity, rather than dissolved oxygen is the limiting water-quality criterion in the Mississinewa River downstream from the Gas City wastewater-treatment facility.

  5. Hawking radiation from AdS black holes (United States)

    Hemming, Samuli; Keski-Vakkuri, Esko


    We investigate Hawking radiation from black holes in (d+1)-dimensional anti-de Sitter space. We focus on s waves, make use of the geometrical optics approximation, and follow three approaches to analyze the radiation. First, we compute a Bogoliubov transformation between Kruskal and asymptotic coordinates and compare the different vacua. Second, following a method due to Kraus, Parikh, and Wilczek, we view Hawking radiation as a tunneling process across the horizon and compute the tunneling probability. This approach uses an anti-de Sitter version of a metric originally introduced by Painlevé for Schwarzschild black holes. From the tunneling probability one also finds a leading correction to the semiclassical emission rate arising from back reaction to the background geometry. Finally, we consider a spherically symmetric collapse geometry and the Bogoliubov transformation between the initial vacuum state and the vacuum of an asymptotic observer.

  6. Logarithmic entropy of Kehagias-Sfetsos black hole with self-gravitation in asymptotically flat IR modified Horava gravity

    International Nuclear Information System (INIS)

    Liu Molin; Lu Junwang


    Motivated by recent logarithmic entropy of Horava-Lifshitz gravity, we investigate Hawking radiation for Kehagias-Sfetsos black hole from tunneling perspective. After considering the effect of self-gravitation, we calculate the emission rate and entropy of quantum tunneling by using Kraus-Parikh-Wilczek method. Meanwhile, both massless and massive particles are considered in this Letter. Interestingly, two types tunneling particles have the same emission rate Γ and entropy S b whose analytical formulae are Γ=exp[π(r in 2 -r out 2 )/2+π/αlnr in /r out ] and S b =A/4+π/αln(A/4), respectively. Here, α is the Horava-Lifshitz field parameter. The results show that the logarithmic entropy of Horava-Lifshitz gravity could be explained well by the self-gravitation, which is totally different from other methods. The study of this semiclassical tunneling process may shed light on understanding the Horava-Lifshitz gravity.

  7. [1400 hours of analysis with Freud: Viktor von Dirsztay. A biographical sketch]. (United States)

    May, Ulrike


    On the basis of mostly unpublished sources, the author reconstructs the life of the Hungarian writer Viktor von Dirsztay (1884?-1935) who was personally acquainted with many expressionist artists and writers, e. g. with Karl Kraus, Oskar Kokoschka, Herwarth Walden, Walter Hasenclever, Hermann Broch and Arthur Schnitzler. This association puts Freud into closer proximity with the cultural avantgarde of his times than previously realized. Between 1910 and 1920 Dirsztay underwent several phases of analysis with Freud; then he was treated by Theodor Reik. The overall length of his analysis with Freud is almost unparalleled. The article discusses whether and in which way Dirsztay's writings might have been influenced by his analyses and how Freud and Reik might have drawn upon their experiences with this patient. It is argued that likely references can be discovered in both authors' theories of masochism. There is an intriguing late remark of Dirsztay's that he was "ruined by analysis".

  8. Die Reporterin Alice Schalek an der Adria

    Mira Miladinović Zalaznik


    Full Text Available Im vorliegenden Beitrag wird die Berichterstattung der einzigen Reporterin, die im Ersten Weltkrieg an die Front geschickt wurde, analysiert. Es handelt sich dabei um jene Artikel, die sich mit der k. u. k. Marine befassen. Schalek wurde wegen ihrer Berichterstattung über die Schlachten in den Dolomiten, am Isonzo, in Serbien, Montenegro oder an der Adria scharf kritisiert und sogar attackiert, da vor allem besonders rücksichtslos von Karl Kraus sowohl in seiner Fackel als in seinem Theaterstück Die letzten Tage der Menschheit. Er hatte an ihr einiges auszusetzen, unter anderem, dass sie eine Frau war und in ihren Artikeln Propaganda betrieb. Im Beitrag soll gezeigt werden, dass Schalek ihre Berichte zwar im Geiste der Habsburgischen Politik verfasste, dass es ihr darin aber nicht nur um Propaganda ging, sondern auch darum, den Kämpfenden eine Stimme zu geben, wobei ihr mitunter trotz Zensur Kritisches zum Zeitgeschehen weiterzugeben gelang.

  9. Measurements of fluorescence and Coster-Kronig yields for 66Dy using synchrotron radiation induced selective photoionization method (United States)

    Kaur, Rajnish; Kumar, Anil; Czyzycki, M.; Migliori, A.; Karydas, A. G.; Puri, Sanjiv


    The L shell fluorescence (ω1, ω2, ω3) and Coster-Kronig (f12, f13, f23) yields for 66Dy have been deduced from the Li (i = 1-3) sub-shell X-ray intensities measured at different incident photon energies across its Li absorption edge energies. Three sets of photoionization cross sections used for determination of these yields include two sets of theoretical values based on the non-relativistic Hartree-Fock-Slater model and the self-consistent Dirac-Hartree-Fock model, and the third one is that deduced from independently measured mass attenuation coefficients of 66Dy. The present experimental fluorescence and Coster-Kronig yields deduced using the self-consistent Dirac-Hartree-Fock model based photoionization cross sections have been found to be in good agreement with the semi-empirical values tabulated by Krause [1] and the Dirac-Hartree-Slater model based values.

    The authors explore a unifying model which couples phase separation and damage processes in a system of partial differential equations. The model has technological applications to solder materials where interactions of both phenomena have been observed and cannot be neglected for a realistic description. The equations are derived in a thermodynamically consistent framework and suitable weak formulations for various types of this coupled system are presented.

  11. Share-of-Surplus Product Line Optimisation with Price Levels

    Directory of Open Access Journals (Sweden)

    X. G. Luo


    Full Text Available Kraus and Yano (2003 established the share-of-surplus product line optimisation model and developed a heuristic procedure for this nonlinear mixed-integer optimisation model. In their model, price of a product is defined as a continuous decision variable. However, because product line optimisation is a planning process in the early stage of product development, pricing decisions usually are not very precise. In this research, a nonlinear integer programming share-of-surplus product line optimization model that allows the selection of candidate price levels for products is established. The model is further transformed into an equivalent linear mixed-integer optimisation model by applying linearisation techniques. Experimental results in different market scenarios show that the computation time of the transformed model is much less than that of the original model.

  12. Mesoporous Silica-Supported Metal Oxide-Promoted Rh Nanocatalyst for Selective Production of Ethanol from Syngas

    Kraus, George


    The objective is to develop a process that will convert synthesis gas from coal into ethanol and then transform the ethanol into hydrogen. Principal investigators from Iowa State University include Dr. George Kraus, Dr. Victor Lin, Marek Pruski, and Dr. Robert Brown. Task 1 involves catalyst development and catalyst scale up. Mesoporous manganese silicate mixed oxide materials will be synthesized, characterized and evaluated. The first-and secondgeneration catalysts have been prepared and scaled up for use in Task 2. The construction of a high-pressure reactor system for producing synthetic liquid fuel from simulated synthesis gas stream has been completed as the first step in Task 2. Using the first- and second generation catalysts, the reactor has demonstrated the production of synthetic liquid fuel from a simulated synthesis gas stream.

  13. Americans Still Overestimate Social Class Mobility: A Pre-Registered Self-Replication. (United States)

    Kraus, Michael W


    Kraus and Tan (2015) hypothesized that Americans tend to overestimate social class mobility in society, and do so because they seek to protect the self. This paper reports a pre-registered exact replication of Study 3 from this original paper and finds, consistent with the original study, that Americans substantially overestimate social class mobility, that people provide greater overestimates when made while thinking of similar others, and that high perceived social class is related to greater overestimates. The current results provide additional evidence consistent with the idea that people overestimate class mobility to protect their beliefs in the promise of equality of opportunity. Discussion considers the utility of pre-registered self-replications as one tool for encouraging replication efforts and assessing the robustness of effect sizes.

  14. Dynamics of quantum discord in a quantum critical environment

    International Nuclear Information System (INIS)

    Xi Zhengjun; Li Yongming; Lu Xiaoming; Sun Zhe


    We study the dynamics of quantum discord (QD) of two qubits independently coupled to an Ising spin chain in a transverse field, which exhibits a quantum phase transition. For this model, we drive the corresponding Kraus operators, obtain the analytic results of QD and compare the dynamics of QD with the dynamics of relative entropy of entanglement nearby the critical point. It is shown that the impact of the quantum criticality environment on QD can be concentrated in a very narrow region nearby the critical point, so it supplies an efficient way to detect the critical points. In the vicinity of the critical point, the evolution of QD is shown to be more complicated than that of entanglement. Furthermore, we find that separable states can also be used to reflect the quantum criticality of the environment.

  15. The salinity effect in a mixed layer ocean model (United States)

    Miller, J. R.


    A model of the thermally mixed layer in the upper ocean as developed by Kraus and Turner and extended by Denman is further extended to investigate the effects of salinity. In the tropical and subtropical Atlantic Ocean rapid increases in salinity occur at the bottom of a uniformly mixed surface layer. The most significant effects produced by the inclusion of salinity are the reduction of the deepening rate and the corresponding change in the heating characteristics of the mixed layer. If the net surface heating is positive, but small, salinity effects must be included to determine whether the mixed layer temperature will increase or decrease. Precipitation over tropical oceans leads to the development of a shallow stable layer accompanied by a decrease in the temperature and salinity at the sea surface.

  16. VizieR Online Data Catalog: Praesepe members rotational periods from K2 LCs (Douglas+, 2017) (United States)

    Douglas, S. T.; Agueros, M. A.; Covey, K. R.; Kraus, A.


    We continue to use the Praesepe membership catalog presented in PaperII (Douglas+, 2014, J/ApJ/795/161), which includes 1130 cluster members with membership probabilities Pmem>=50% as calculated by Kraus & Hillenbrand (2007, J/AJ/134/2340) and 39 previously identified members too bright to be included by those authors in their catalog for the cluster. We assign these bright stars Pmem=100%. We also continue to use the photometry and stellar masses presented in Table 5 of Paper II. For most of our analysis, as in that work, we include only the 1099 stars with Pmem>=70%. K2 targeted Praesepe in its Campaign 5. We analyze the resulting long-cadence data for 794 Praesepe members. We present Prot for 677 K2 targets. Of these, 471 are new measurements. (3 data files).

  17. Universal cross sections for K-shell ionization by low-velocity protons; importance of relativistic and energy-loss effects

    International Nuclear Information System (INIS)

    Zander, A.R.; Lapicki, G.


    When Z 1 2 , inner-shell ionization of a target atom of atomic number Z 2 by a projectile of atomic number Z 1 occurs predominately via removal of an inner-shell electron to the target atom continuum (direct ionization). Electron capture contributes then insignificantly to the ionization, and thus the predictions of perturbativein-Z 1 /Z 2 theories of direct ionization can be tested through comparison with measured ionization cross sections. We present such a comparison with the recently reported data for K-shell ionization of the Z 2 =22, 26, 28, and 30 elements by 60-150 keV protons (Z 1 =1). These ionization cross sections were inferred from x-ray production measurements using Krause's fluorescence yields

    The chemical composition of Spathelia excelsa (Krause) R. S. Cowan and Brizicky was investigated and the limonoids harrisonin (1) and deacetylspathelin (2), alkaloids folinin and casimiroin mixture (3a,b), plus a further casimiroin (3b) were identified in methanol extract from root. The CH 2 Cl 2 extract from the rachis yielded protolimonoid 3β-angeloyl-21,24-epoxy-7α,21α,23α,25-tetrahydroxy-4α,4β,8β,10β-tetramethyl -25-dimethyl-14,18-cyclo-5α,13α,14α,17α-cholestane (4), and methanol extract, the limonoids limonin diosphenol (5) and perforatin (6), as well as the chromone biflorin (7). Harrisonin and biflorin were isolated for the first time in this genus. On the antifungal assay against witches' broom (Moniliophthora perniciosa) compound 3b was found to be active. (author)

  19. Effect of vanadium neighbors on the hyperfine properties of iron-vanadium alloys

    Energy Technology Data Exchange (ETDEWEB)

    Elzain, M., E-mail:; Yousif, A.; Gismelseed, A.; Al Rawas, A.; Widatallah, H.; Bouziane, K.; Al-Omari, I. [College of Science, Sultan Qaboos University, Physics Department (Oman)


    The electronic and magnetic structures of Fe-V alloys are calculated using the discrete-variational and full-potential linearized-augmented-plane wave methods. The derived hyperfine properties at Fe sites are studied against the number of Fe atoms in the neighbouring shells. As expected the magnetic hyperfine field depends strongly on the number of Fe atoms in the first and second shells of neighbours while its dependence on the variation of atoms in the third shell is weak. The calculated distribution of the magnetic hyperfine fields at the Fe sites, are compared to the experimental data of Krause et al. (Phys Rev B 61:6196-6204, 2000). The contact charge densities and the magnetic moments are also calculated. It was found that the contact charge density increases with increasing V contents and this leads to negative isomer shift on addition of V.

  20. Towards generic adiabatic elimination for bipartite open quantum systems (United States)

    Azouit, R.; Chittaro, F.; Sarlette, A.; Rouchon, P.


    We consider a composite open quantum system consisting of a fast subsystem coupled to a slow one. Using the time scale separation, we develop an adiabatic elimination technique to derive at any order the reduced model describing the slow subsystem. The method, based on an asymptotic expansion and geometric singular perturbation theory, ensures the physical interpretation of the reduced second-order model by giving the reduced dynamics in a Lindblad form and the state reduction in Kraus map form. We give explicit second-order formulas for Hamiltonian or cascade coupling between the two subsystems. These formulas can be used to engineer, via a careful choice of the fast subsystem, the Hamiltonian and Lindbald operators governing the dissipative dynamics of the slow subsystem.

  2. Gleason-Busch theorem for sequential measurements (United States)

    Flatt, Kieran; Barnett, Stephen M.; Croke, Sarah


    Gleason's theorem is a statement that, given some reasonable assumptions, the Born rule used to calculate probabilities in quantum mechanics is essentially unique [A. M. Gleason, Indiana Univ. Math. J. 6, 885 (1957), 10.1512/iumj.1957.6.56050]. We show that Gleason's theorem contains within it also the structure of sequential measurements, and along with this the state update rule. We give a small set of axioms, which are physically motivated and analogous to those in Busch's proof of Gleason's theorem [P. Busch, Phys. Rev. Lett. 91, 120403 (2003), 10.1103/PhysRevLett.91.120403], from which the familiar Kraus operator form follows. An axiomatic approach has practical relevance as well as fundamental interest, in making clear those assumptions which underlie the security of quantum communication protocols. Interestingly, the two-time formalism is seen to arise naturally in this approach.

    Developing many of the major, exciting, pre- and post-millennium developments from the ground up, this book is an ideal entry point for graduate students into quantum information theory. Significant attention is given to quantum mechanics for quantum information theory, and careful studies of the important protocols of teleportation, superdense coding, and entanglement distribution are presented. In this new edition, readers can expect to find over 100 pages of new material, including detailed discussions of Bell's theorem, the CHSH game, Tsirelson's theorem, the axiomatic approach to quantum channels, the definition of the diamond norm and its interpretation, and a proof of the Choi–Kraus theorem. Discussion of the importance of the quantum dynamic capacity formula has been completely revised, and many new exercises and references have been added. This new edition will be welcomed by the upcoming generation of quantum information theorists and the already established community of classical information theo...

  4. Francisco Giner and Adolfo Posada, precursors of the League of Nations

    Directory of Open Access Journals (Sweden)

    Delia Manzanero


    Full Text Available This paper presents the contributions to the process of formation of the League of Nations which, from sociological and legal premises present in the enlightened ideas of the German philosopher Krause, were designed and represented by two eminent Spanish Krausist jurists, Giner and Posada. First, we will analyse the influence of the teleological tradition of the Interessenjurisprudenz in Krausist legal philosophy, and the function of this iusphilosophical trend as a modernising and emancipating movement from the prevailing positivist formalism of the time. Secondly, we will delve into the basic principles of the Krausist sociological and legal theory which have been a major factor of Europeanisation, for which we will review his most scathing criticism to the European doctrines of imperial nationalism. Finally, we will address the role of Krausism in the promotion and defense of Wilson's Fourteen Points and the League of Nations, and its views on what should be subject to contestation in terms of international law.

  5. Benjamin's Voices: Irresolution and Textual Practice in ON THE CONCEPT OF HISTORY

    Directory of Open Access Journals (Sweden)

    Lawrence S. Wang


    Full Text Available Benjamin’s final treatise On the Concept of History has generated significant criticism with its profound yet enigmatic statements on his historical materialism. Its internal references range from the philosopher Hegel to satirist Karl Kraus; these interludes of scientific and poetic language have garnered notable readings through Marxian lenses, as well as ample theological and literary interpretations. Reading against any simplified tradition of unity, I suggest instead an insoluble collection of distinct voices at play in the entanglements of the text. Constellating these ‘Benjamins’ as self-conscious reflective and speculative identities nonetheless actualizing to their human character, this article illustrates a text which is intrinsically in deep conversation with its own medial limitation and consequently transforms that textuality into a locus of power. Structurally, Benjamin’s theses perform a harmonic, musical feat, embedding a true praxis of historical critique within an image from which it unendingly springs forth.

  6. Internationalization Process and Technological Capability Trajectory of Iguaçu

    Rafael Kuramoto Gonzalez


    Full Text Available This article focuses on the influence of the internationalization process in the evolution of technological capability. This implication was studied in Iguaçu between 1967 and 2009. To achieve the proposed goal it was used the Internationalization of Brazilian Export Producer Companies Model, built by Kraus (2006 and the Model of Technological Capabilities in Companies of Emerging Economies, built by Figueiredo (2004. The study found that different stages of internationalization require different functions and different levels of technology. The discussion proposed by this paper found a close association between the process of internationalization and the development of technological capability in the company studied. It can be concluded that for companies of Soluble Coffee to conquer, reach and remain competitive in international markets it should engage efforts to build diverse organizational skills, alliances and technological capabilities.

  10. 150 kW Class Solar Electric Propulsion Spacecraft Power Architecture Model (United States)

    Csank, Jeffrey T.; Aulisio, Michael V.; Loop, Benjamin


    The National Aeronautics and Space Administration (NASA) Solar Electric Propulsion Technology Demonstration Mission in conjunction with PC Krause and Associates has created a Simulink-based power architecture model for a 50 kilo-Watt (kW) solar electric propulsion system. NASA has extended this model to investigate 150 kW solar electric propulsion systems. Increasing the power system capability from 50 kW to 150 kW better aligns with the anticipated power requirements for Mars and other deep space explorations. The high-power solar electric propulsion capability has been identified as a critical part of NASAs future beyond-low-Earth-orbit for human-crewed exploration missions. This paper presents multiple 150 kW architectures, simulation results, and a discussion of their merits.

  11. Fine structure of primary afferent axon terminals projecting from rapidly adapting mechanoreceptors of the toe and foot pads of the cat. (United States)

    Maxwell, D J; Bannatyne, B A; Fyffe, R E; Brown, A G


    Two Pacinian corpuscle afferents and two rapidly adapting afferents from Krause corpuscles were intra-axonally labelled with horseradish peroxidase in the lumbosacral enlargement of the cat's spinal cord. Tissue was prepared for combined light and electron microscopical analysis. Boutons from both classes of afferent had similar ultrastructural appearances. They both formed from one to three synaptic junctions with dendritic shafts and spines and received axo-axonic synapses. In addition, both categories of bouton were seen to be presynaptic to structures interpreted as vesicle-containing dendrites. It is concluded that both types of afferent fibre are subject to presynaptic control and that they synapse with dorsal horn neurones which are possibly interneurones involved in primary afferent depolarization and post-synaptic dorsal column neurones.

  12. The nerve endings of the acetabular labrum. (United States)

    Kim, Y T; Azuma, H


    The nerve endings of the human acetabular labrum were investigated. Twenty-three acetabular labra were obtained from 24 fresh human cadavers, stained with Suzuki's silver impregnation and an immunohistochemical technique for neurogenic specific protein S-100, and examined by light and electron microscopy. Ramified free nerve endings were seen in all specimens by silver staining, and also were observed by the immunohistochemical technique for S-100 protein. Sensory nerve end organs, such as a Vater-Pacini corpuscle, Golgi-Mazzoni corpuscle, Ruffini corpuscle, and articular corpuscle (Krause corpuscle), were observed by silver staining. Collagen fibers were scattered sparsely in the superficial layer of the labrum, and nerve endings were observed mostly in this region. Collagen fibers were sparse, and nerve endings also were observed in some regions among the collagen fiber bundles in the inner layer. Innervation of the acetabular labrum was confirmed in this study, suggesting that nerve endings in the labrum may be involved in nociceptive and proprioceptive mechanisms.

  13. Nerve endings in the heart of teleosts. (United States)

    Kumar, S


    The nerve endings in the heart of fishes were studied using silver impregnation techniques. The heart chambers are profusely innervated by the sympathetic, parasympathetic (vagal) and postganglionic fibers of the intracardiac ganglia situated at the sinuatrial and the atrioventricular junctions. The plexuses are composed of medullated and nonmedullated fibers. The nerve fibers generally end freely and are slightly branched or unbranched terminations of myelinated and unmyelinated fibers. Moreover, a few nerve fibers end redundant in the form of end-rings, bulb-like, bush-like, club-shaped end end-coil like structures. The complex unencapsulated types of endings are also found in the myocardium of the atrium and the ventricle. The encapsulated endings (Vater-Pacinian; Krause end-bulb) could not be observed.

    Krysko, Kenneth L.; Hart, Kristen M.; Smith, Brian J.; Selby, Thomas H.; Cherkiss, Michael S.; Coutu, Nicholas T.; Reichart, Rebecca M.; Nuñez, Leroy P.; Mazzotti, Frank J.; Snow, Ray W.


    The Burmese Python, Python bivittatus Kuhl 1820 (Squamata: Pythonidae), is indigenous to northern India,east to southern China, and south to Vietnam and a few islands in Indonesia (Barker and Barker 2008, Reed and Rodda 2009). This species has been introduced since at least 1979 in southern Florida, USA, where it likely began reproducing and became established during the 1980s (Meshaka et al. 2000, Snowet al. 2007b,Kraus 2009, Krysko et al. 2011, Willson et al. 2011). Python bivittatus has been documented in Florida consuming a variety of mammals and birds, and the American Alligator(Alligator mississippiensis) (Snowet al. 2007a, 2007b; Harvey et al. 2008; Rochford et al. 2010b; Holbrook and Chesnes 2011), many of which are protected species. Herein, we provide details on two of the largest known wild P. bivittatus in Florida to date, including current records on length,mass,clutch size, and diet.

    The L 1 and L 2 sub-shell fluorescence yields have been deduced for elements with 64 ≤ Z ≤ 70 from the L k (k = l, α, β 1,4 , β 3,6 , β 2,15,9,10,7 , γ 1,5 and γ 2,3,4 ) X-ray production cross sections measured at 22.6 keV incident photon energy using a spectrometer involving a disc type radioisotope of Cd 109 as a photon source and a Peltier cooled X-ray detector. The incident photon intensity, detector efficiency and geometrical factor have been determined from the K X-ray yields emitted from elemental targets with 20 ≤ Z ≤ 42 in the same geometrical setup and from knowledge of the K shell cross sections. The present deduced ω 1 (exp) values, for elements with 64 ≤ Z ≤ 70, are found to be in good agreement with those tabulated by Campbell (J.L. Campbell, Atom. Data Nucl. Data Tables 95 (2009) 115), where as these are, on an average, higher by 19% and 24% than those based on the Dirac-Hartree-Slater model (S. Puri et al., X-ray Spectrometry 22 (1993) 358) and the semi-empirical values compiled by Krause (M.O. Krause, J. Phys. Chem. Ref. Data 8 (1979) 307), respectively. The present deduced ω 2 (exp) values are found to be in good agreement with those based on the Dirac-Hartree-Slater model and are higher by up to ∼13% than the semi-empirical values for the elements under investigation.

  17. Theoretical & Experimental Studies of Elementary Particles

    Energy Technology Data Exchange (ETDEWEB)

    McFarland, Kevin [Univ. of Rochester, NY (United States)


    Abstract High energy physics has been one of the signature research programs at the University of Rochester for over 60 years. The group has made leading contributions to experimental discoveries at accelerators and in cosmic rays and has played major roles in developing the theoretical framework that gives us our ``standard model'' of fundamental interactions today. This award from the Department of Energy funded a major portion of that research for more than 20 years. During this time, highlights of the supported work included the discovery of the top quark at the Fermilab Tevatron, the completion of a broad program of physics measurements that verified the electroweak unified theory, the measurement of three generations of neutrino flavor oscillations, and the first observation of a ``Higgs like'' boson at the Large Hadron Collider. The work has resulted in more than 2000 publications over the period of the grant. The principal investigators supported on this grant have been recognized as leaders in the field of elementary particle physics by their peers through numerous awards and leadership positions. Most notable among them is the APS W.K.H. Panofsky Prize awarded to Arie Bodek in 2004, the J.J. Sakurai Prizes awarded to Susumu Okubo and C. Richard Hagen in 2005 and 2010, respectively, the Wigner medal awarded to Susumu Okubo in 2006, and five principal investigators (Das, Demina, McFarland, Orr, Tipton) who received Department of Energy Outstanding Junior Investigator awards during the period of this grant. The University of Rochester Department of Physics and Astronomy, which houses the research group, provides primary salary support for the faculty and has waived most tuition costs for graduate students during the period of this grant. The group also benefits significantly from technical support and infrastructure available at the University which supports the work. The research work of the group has provided educational opportunities

  18. Uranium resources in fine-grained carbonaceous rocks of the Great Divide Basin, south-central Wyoming. National Uranium Resource Evaluation

    International Nuclear Information System (INIS)

    Burger, J.A.; Roe, L.M. II; Hacke, C.M.; Mosher, M.M.


    The uranium resources of the fine-grained carbonaceous rocks of the Great Divide Basin in southern Wyoming were assessed. The assessment was based primarily on data from some 600 boreholes. The data included information from geophysical logs, lithologic logs and cores, and drill cuttings. The cores and cuttings were analyzed for chemical U 3 O 8 , radiometric U, Th and trace elements. Selected samples were examined by thin section, sieve analysis, x-ray, SEM, ion probe, and alpha track methods. The uranium is associated with fine-grained carbonaceous shales, siltstones, mudstones, and coals in radioactive zones 5 to 50 ft thick that are continuous over broad areas. These rocks have a limited stratigraphic range between the Red Desert tongue of the Wasatch Formation and the lower part of the Tipton tongue of the Green River Formation. Most of this uranium is syngenetic in origin, in part from the chelation of the uranium by organic material in lake-side swamps and in part as uranium in very fine detrital heavy minerals. The uraniferous fine-grained carbonaceous rocks that exceed a cutoff grade of 100 ppM eU 3 O 8 extend over an area of 542 mi 2 and locally to a depth of approximately 2000 ft. The uraniferous area is roughly ellipical and embraces the zone of change between the piedmont and alluvial-fan facies and the lacustrine facies of the intertonguing Battle Spring, Wasatch, and Green River Formations. About 1.05 x 10 6 tons U 3 O 8 , based on gross-gamma logs not corrected for thorium, are assigned to the area in the first 500 ft; an estimated 3.49 x 10 6 tons are assigned to a depth of 1000 ft. These units also contain a substantial thorium resource that is also associated with fine-grained rocks. The thorium-to-uranium ratio generally ranges between 1 and 4. A thorium resource of 3.43 x 10 6 tons to a depth of 500 ft is estimated for the assessment area. 5 figures, 3 tables

  19. Effect of an axially-symmetric cyclonic vortex on the sea surface temperature in the Gulf of Mexico

    Villanueva, E.E.; Mendoza, V.M.; Adem, J. [Universidad Nacional Autonoma de Mexico, Mexico, D.F. (Mexico)]. E-mail:


    A model for the mixed layer of the Gulf of Mexico has been used to determine the effect that an idealized cyclonic vortex has in the sea surface temperature. The model consists of the equations of conservation of thermal energy and this of balance between mechanical energy and thermal energy, last based on the Kraus-Turner theory; both equations are vertically integrated in the mixed layer. As atmospheric forcing, we prescribe the surface wind associated with an axially-symmetric cyclonic vortex characterized by two parameters: the maximum tangential velocity and the radius at which that velocity is reached. The values of these two parameters, which depend on the position of the vortex, correspond to two cases: hurricane Hilda, which crossed the central part of the Gulf of Mexico between September 29 and October 3, 1964 and hurricane Gilbert whose trajectory between 11 and 17 September, 1988 crossed the Caribbean Sea, the Yucatan Peninsula and the southwest Gulf of Mexico. The results show that a cyclonic vortex with such characteristics, produce during its passage by the sea vertical turbulent water transport through the thermocline (entrainment) that is able to cool down the mixed layer in several degrees and increases the thermocline depth in several meters, in agreement with the observations.

El modelo consiste basicamente de dos ecuaciones, la de conservacion de energia termica y la de balance entre energia mecanica y energia termica, esta ultima derivada de la teoria de Kraus-Turner; ambas ecuaciones son verticalmente integradas y acopladas en la capa de mezcla. Como forzamiento atmosferico sobre la superficie del mar se prescribe el viento asociado a un vortice ciclonico axialmente simetrico caracterizado por dos parametros: la velocidad tangencial maxima y el radio al

  2. Immunohistochemical analysis of mechanoreceptors in the human posterior cruciate ligament: a demonstration of its proprioceptive role and clinical relevance. (United States)

    Del Valle, M E; Harwin, S F; Maestro, A; Murcia, A; Vega, J A


    Although long-term studies report successful results with total knee arthroplasty (TKA), performed with or without posterior cruciate ligament (PCL) retention, controversy exists as to which is preferable in regard to patient outcome and satisfaction. The possible proprioceptive role of the PCL may account for a more normal feeling of the arthroplasty. Although the PCL has been examined using various histological techniques, immunohistochemical techniques are the most sensitive for neural elements. Therefore an immunohistochemical study was designed to determine the patterns of innervation, the morphological types of the proprioceptors, and their immunohistochemical profile. During TKA, samples were obtained from 22 osteoarthritic PCLs and subjected to immunohistochemical analysis with mouse monoclonal antibodies against neurofilament protein (NFP), S100 protein (S100P), epithelial membrane antigen (EMA), and vimentin (all present in neuromechanoreceptors). Three normal PCLs from cadaveric specimens were also obtained and analyzed for comparison. Five types of sensory corpuscles were observed in both the normal and the arthritic PCLs: simple lamellar, Pacini-like, Ruffini, Krause-like, and morphologically unclassified. Their structure included a central axon, inner core, and capsule in lamellar and Pacini corpuscles and variable intracorpuscular axons and periaxonal cells in the Ruffini and Krause-like corpuscles. The immunohistochemical profile showed the central axon to have NFP immunoreactivity, periaxonal cells to have S100P and vimentin immunoreactivity, and the capsule to have EMA and vimentin immunoreactivity. Nerve fibers and free nerve endings displayed NFP and S100P immunoreactivity. The immunohistochemical profile of the PCL sensory corpuscles is almost identical to that of cutaneous sensory corpuscles. Some prior histological studies of the PCL reported Golgi-like mechanoreceptors, and others found encapsulated corpuscles but no Golgi-like structures

    Kovácsné Bobály, Viktória; Szilágyi, Brigitta; Makai, Alexandra; Koller, Ákos; Járomi, Melinda


    Ballet dancers often suffer from low back pain. Low back pain can be reduced by strengthening the core muscles with the help of a special exercise program. In the study 62 ballet dancer women (average age: 14.89 ± 1.21 years) were included. Intervention group: n = 30 participant, average age: 14.86 ± 1.00 years, control group: n = 32 participant, average age: 14.91 ± 1.37 years. We examined the pain intensity that occurs during training with visual analog scale, the habitual posture with photogrammetry, the abdominal muscle strength with Kraus-Weber test, the static muscle strength of the trunk muscles with core test and the lumbar motor control with leg lowering test. The intervention group did a trunk prevented exercise program during 3 months, and then we examined them again. In the intervention group the intensity of pain significantly decreased (VAS1: p = 0.012; VAS2: p = 0.021), the abdominal muscle strength significantly improved (K-W. B: p=0.025; K-W. C: pCore-test: pexercise program, which improves the conditions of trunk muscles, the motor control of lumbar regions can be improved and the lower back pain and the incidence of injuries can be reduced.

  5. Recommendations for diagnosing a mild traumatic brain injury: a National Academy of Neuropsychology education paper. (United States)

    Ruff, Ronald M; Iverson, Grant L; Barth, Jeffrey T; Bush, Shane S; Broshek, Donna K


    A special interest group of the American Congress of Rehabilitation Medicine [ACRM; Mild Traumatic Brain Injury Committee. (1993). Definition of mild traumatic brain injury. Journal of Head Trauma Rehabilitation, 8 (3), 86-87.] was the first organized interdisciplinary group to advocate four specific criteria for the diagnosis of a mild traumatic brain injury (TBI). More recently, the World Health Organization (WHO) Collaborative Center Task Force on Mild Traumatic Brain Injury [Carroll, L. J., Cassidy, J. D., Holm, L., Kraus, J., & Coronado, V. G. (2004). Methodological issues and research recommendations for mild traumatic brain injury: the WHO Collaborating Centre Task Force on Mild Traumatic Brain Injury. Journal of Rehabilitation Medicine, (Suppl. 43), 113-125.] conducted a comprehensive review of the definitions utilized in evidence-based studies with mild TBI patients. Based on this review, the WHO task force maintained the same four criteria but offered two modifications. The similarities and differences between these two definitions are discussed. The authors of the ACRM and the WHO definitions do not provide guidelines or specific recommendations for diagnosing the four criteria. Thus, we provide recommendations for assessing loss of consciousness, retrograde and post-traumatic amnesia, disorientation and confusion as well as clarification of the neurologic signs that can be indicative of a diagnosis of mild TBI. Finally, confounding factors mentioned in both definitions that should exclude a mild TBI diagnosis are summarized.

    Rodrigo Zuleta


    Full Text Available Hace unos cuarenta años, apareció en la editorial española Tauros un breve libro del entonces joven ensayista colombiano Rafael Gutiérrez Girardot titulado En torno a la literatura alemana actual. Para sorpresa de algunos lectores, en el libro de Gutiérrez no se hablaba de nombres previsibles como Kafka, Thomas Mann o Rainer Maria Rilke, que ya entonces tenían un público entre los lectores de lengua española, sino que se dedicaba a autores más o menos secretos en el mundo hispánico, en ese entonces, como Ernst Jünger, Karl Kraus y Gottfried Benn o, aún hoy, casi completamente secretos, como Eugen Gottlob Winkler y Max Komerell. Esa preferencia del joven ensayista por autores secretos anticipaba lo que sería después una de las características fundamentales de su trabajo: el rechazo a las modas y la voluntad de abrir siempre nuevos horizontes con su trabajo.

  7. The influence of entanglement and decoherence on the quantum Stackelberg duopoly game

    International Nuclear Information System (INIS)

    Zhu Xia; Kuang, L-M


    In this paper, we investigate the influence of entanglement and decoherence on the quantum Stackelberg duopoly (QSD) game. It is shown that the first-mover advantage can be weakened or enhanced due to the existence of entanglement for the QSD game without decoherence. The influence of decoherence induced by the amplitude damping and the phase damping are explicitly studied in the formalism of Kraus operator representations. We show that the amplitude damping drastically changes the Nash equilibrium of the QSD game and the profits of the two players while the phase damping does not affect the Nash equilibrium and the profits of the two players. It is found that under certain conditions there exists a 'critical point' of the damping parameter for the amplitude damping environment. At the 'critical point' the two players have the same moves and payoffs. The QSD game can change from the first-mover advantage game into the follower-mover advantage game when the damping parameter varies from the left-hand-side regime of the 'critical point' to the right-hand-side regime

  8. Tellurium Stable Isotopes as a Paleoredox Proxy (United States)

    Wasserman, N.; Johnson, T. M.


    Despite arguments for variably-oxygenated shallow waters and anoxic deep marine waters, which delayed animal development until the Neoproterozoic Oxidation Event, the magnitude of atmospheric oxygen during the Proterozoic is still uncertain [1]. The evidence for low pO2 (biologic reduction of Te(VI) or Te(IV) to elemental Te(0) [3, 4]. Utilizing hydride generation MC-ICP-MS, we are able to obtain high precision (2σ 0.04‰) measurements of δ128Te/125Te for natural samples containing < 10 ng of Te. A suite of Phanerozoic and Proterozoic ironstones show significant variation in δ128Te/125Te (<0.5‰), suggesting that the Te redox cycle was active during the Proterozoic. Future directions will include Te isotope measurements of Precambrian paleosols to determine natural isotope variation before the Great Oxidation Event and experiments to determine fractionation during adsorption to Fe-oxyhydroxides.

  9. Plasma versus Drude Modeling of the Casimir Force: Beyond the Proximity Force Approximation (United States)

    Hartmann, Michael; Ingold, Gert-Ludwig; Neto, Paulo A. Maia


    We calculate the Casimir force and its gradient between a spherical and a planar gold surface. Significant numerical improvements allow us to extend the range of accessible parameters into the experimental regime. We compare our numerically exact results with those obtained within the proximity force approximation (PFA) employed in the analysis of all Casimir force experiments reported in the literature so far. Special attention is paid to the difference between the Drude model and the dissipationless plasma model at zero frequency. It is found that the correction to PFA is too small to explain the discrepancy between the experimental data and the PFA result based on the Drude model. However, it turns out that for the plasma model, the corrections to PFA lie well outside the experimental bound obtained by probing the variation of the force gradient with the sphere radius [D. E. Krause et al., Phys. Rev. Lett. 98, 050403 (2007), 10.1103/PhysRevLett.98.050403]. The corresponding corrections based on the Drude model are significantly smaller but still in violation of the experimental bound for small distances between plane and sphere.

  10. Emerging dynamics arising from coarse-grained quantum systems (United States)

    Duarte, Cristhiano; Carvalho, Gabriel Dias; Bernardes, Nadja K.; de Melo, Fernando


    The purpose of physics is to describe nature from elementary particles all the way up to cosmological objects like cluster of galaxies and black holes. Although a unified description for all this spectrum of events is desirable, this would be highly impractical. To not get lost in unnecessary details, effective descriptions are mandatory. Here we analyze the dynamics that may emerge from a full quantum description when one does not have access to all the degrees of freedom of a system. More concretely, we describe the properties of the dynamics that arise from quantum mechanics if one has access only to a coarse-grained description of the system. We obtain that the effective maps are not necessarily of Kraus form, due to correlations between accessible and nonaccessible degrees of freedom, and that the distance between two effective states may increase under the action of the effective map. We expect our framework to be useful for addressing questions such as the thermalization of closed quantum systems, as well as the description of measurements in quantum mechanics.

  11. Prediction problem for target events based on the inter-event waiting time (United States)

    Shapoval, A.


    In this paper we address the problem of forecasting the target events of a time series given the distribution ξ of time gaps between target events. Strong earthquakes and stock market crashes are the two types of such events that we are focusing on. In the series of earthquakes, as McCann et al. show [W.R. Mc Cann, S.P. Nishenko, L.R. Sykes, J. Krause, Seismic gaps and plate tectonics: seismic potential for major boundaries, Pure and Applied Geophysics 117 (1979) 1082-1147], there are well-defined gaps (called seismic gaps) between strong earthquakes. On the other hand, usually there are no regular gaps in the series of stock market crashes [M. Raberto, E. Scalas, F. Mainardi, Waiting-times and returns in high-frequency financial data: an empirical study, Physica A 314 (2002) 749-755]. For the case of seismic gaps, we analytically derive an upper bound of prediction efficiency given the coefficient of variation of the distribution ξ. For the case of stock market crashes, we develop an algorithm that predicts the next crash within a certain time interval after the previous one. We show that this algorithm outperforms random prediction. The efficiency of our algorithm sets up a lower bound of efficiency for effective prediction of stock market crashes.

  12. Talcum induced pneumoconiosis following inhalation of adulterated marijuana, a case report

    Directory of Open Access Journals (Sweden)

    Scheel Andreas


    Full Text Available Abstract Background Talcosis, a granulomatous inflammation of the lungs caused by inhalation of talcum dust, is a rare form of pneumoconiosis. Besides inhalative occupational exposure, intravenous abuse of adulterated drugs is a major cause for this condition. Minerals such as talcum (magnesium silicate and sand (predominant silicon dioxide are used to increase both volume and weight of illicit substances. In intravenous heroin-abuse, talcosis is a well-known complication. Here we describe a case of talcosis caused by inhalative abuse of adulterated marijuana. Clinical history A 29-year old man presented with persistent fever, dyspnea and cervical emphysema. He admitted consumption of 'cut' marijuana for several years, preferentially by water pipe smoking. Morphologic findings Lung-biopsies showed chronic interstitial lung disease, anthracotic pigments and birefringent material. Energy dispersive x-ray spectroscopy revealed silicon-containing particles (1-2 μm and fine aluminum particles ( Conclusions The exacerbated chronic interstitial lung disease in a 29-year old patient could be attributed to his prolonged abuse of talcum-adulterated marjuana by histopathology and x-ray spectroscopy. Since cannabis consumption is widely spread among young adults, it seems to be justified to raise attention to this form of interstitial pulmonary disease.

  13. Invasive reptiles and amphibians: global perspectives and local solutions (United States)

    Reed, R.N.; Kraus, F.


    In the annals of invasive species biology, higher taxa such asmammals, plants and insects have received the lion’s shareof research attention, largely because many of these invadershave demonstrated a remarkable ability to degrade ecosys-tems and cause economic harm. Interest in invasive reptilesand amphibians (collectively ‘herpetofauna’, colloquially‘herps’) has historically lagged but is now garnering in-creased scrutiny as a result of their escalating pace ofinvasion. A few herpetofaunal invaders have received con-siderable attention in scientific and popular accounts, in-cluding the brown treesnakeBoiga irregularison Guam,Burmese pythonPython molurusin Florida, Coqu´ıEleutherodactylus coquiin Hawaii and cane toadBufomarinusin Australia. However, relatively few are aware ofmany emerging and potentially injurious herpetofaunalinvaders, such as Nile monitorsVaranus niloticusin Flor-ida, common kingsnakesLampropeltis getulain the CanaryIslands, boa constrictorsBoa constrictoron Aruba andCozumel, or a variety of giant constrictor snakes in PuertoRico. For the vast majority of the most commonlyintroduced species, real or potential impacts to nativeecosystems or human economic interests are poorly under-stood and incompletely explored; major pathways of intro-duction have only recently been elucidated, and effectivemanagement interventions have been limited (Kraus, 2009).

Haplodrassus pseudosignifer is a new species record for Crimea and Ukraine as a whole, with Crimea as the westernmost point of its distribution range. Haplodrassus invalidus is recorded for the first time for the fauna of Azerbaijan, Caucasus and the former Soviet Union. Azerbaijan is the easternmost point of its known distribution range. All Crimean Haplodrassus species have only one peak of activity of adult specimens during the year.

  17. Color-avoiding percolation (United States)

    Krause, Sebastian M.; Danziger, Michael M.; Zlatić, Vinko


    Many real world networks have groups of similar nodes which are vulnerable to the same failure or adversary. Nodes can be colored in such a way that colors encode the shared vulnerabilities. Using multiple paths to avoid these vulnerabilities can greatly improve network robustness, if such paths exist. Color-avoiding percolation provides a theoretical framework for analyzing this scenario, focusing on the maximal set of nodes which can be connected via multiple color-avoiding paths. In this paper we extend the basic theory of color-avoiding percolation that was published in S. M. Krause et al. [Phys. Rev. X 6, 041022 (2016)], 10.1103/PhysRevX.6.041022. We explicitly account for the fact that the same particular link can be part of different paths avoiding different colors. This fact was previously accounted for with a heuristic approximation. Here we propose a better method for solving this problem which is substantially more accurate for many avoided colors. Further, we formulate our method with differentiated node functions, either as senders and receivers, or as transmitters. In both functions, nodes can be explicitly trusted or avoided. With only one avoided color we obtain standard percolation. Avoiding additional colors one by one, we can understand the critical behavior of color-avoiding percolation. For unequal color frequencies, we find that the colors with the largest frequencies control the critical threshold and exponent. Colors of small frequencies have only a minor influence on color-avoiding connectivity, thus allowing for approximations.

  18. Transport features of nano-hydroxylapatite (n-HA) embedded silicone rubber (SR) systems: influence of SR/n-HA interaction, degree of reinforcement and morphology. (United States)

    M, Bindu; G, Unnikrishnan


    We report the transport characteristics of silicone rubber/nano-hydroxylapatite (SR/n-HA) systems at room temperature with reference to the effects of n-HA loading, morphology and penetrant nature, using toluene, xylene, ethyl acetate and butyl acetate in the liquid phase and methanol, ethanol, 1-propanol, 2-propanol and butanol in the vapour phase as probe molecules. The interaction between the n-HA particles and SR matrix has been confirmed by FTIR analysis. As the n-HA content in the SR matrix increased, the penetrant uptake has been found to decrease. The observations have been correlated with the density and void content of the systems. Scanning electron microscopy images have been found to be complementary to the observed transport features. The reinforcement effect of n-HA particles on the SR matrix has been verified by Kraus equation. Molecular mass between the cross links has been observed to decrease with an increase in n-HA loading. The results have been compared with affine, phantom network, parallel, series and Maxwell models. The transport data have been complemented by observations on biological fluid uptake with urea, d-glucose, KI, saline water, phosphate buffer and artificial urine as the media.

  19. Leader's opinion priority bounded confidence model for network opinion evolution (United States)

    Zhu, Meixia; Xie, Guangqiang


    Aiming at the weight of trust someone given to participate in the interaction in Hegselmann-Krause's type consensus model is the same and virtual social networks among individuals with different level of education, personal influence, etc. For differences between agents, a novelty bounded confidence model was proposed with leader's opinion considered priority. Interaction neighbors can be divided into two kinds. The first kind is made up of "opinion leaders" group, another kind is made up of ordinary people. For different groups to give different weights of trust. We also analyzed the related characteristics of the new model under the symmetrical bounded confidence parameters and combined with the classical HK model were analyzed. Simulation experiment results show that no matter the network size and initial view is subject to uniform distribution or discrete distribution. We can control the "opinion-leader" good change the number of views and values, and even improve the convergence speed. Experiment also found that the choice of "opinion leaders" is not the more the better, the model well explain how the "opinion leader" in the process of the evolution of the public opinion play the role of the leader.

  20. Nerves and nerve endings in the skin of tropical cattle. (United States)

    Amakiri, S F; Ozoya, S E; Ogunnaike, P O


    The nerves and nerve endings in the skin of tropical cattle were studied using histological and histochemical techniques. Many nerve trunks and fibres were present in the reticular and papillary dermis in both hairy and non-hairy skin sites. In non-hairy skin locations such as the muzzle and lower lip, encapsulated endings akin to Krause and Ruffini end bulbs, which arise from myelinated nerve trunks situated lower down the dermis were observed at the upper papillary layer level. Some fibre trunks seen at this level extended upwards to terminate within dermal papillae as bulb-shaped longitudinally lamellated Pacinian-type endings, while other onion-shaped lamellated nerve structures were located either within dermal papillae or near the dermo-epidermal area. Intraepidermal free-ending nerve fibres, appearing non-myelinated were observed in areas with thick epidermis. Intraepidermal free-ending nerve fibres, appearing non-myelinated were observed in areas with thick epidermis. On hairy skin sites, however, organized nerve endings or intraepidermal nerve endings were not readily identifiable.

    Full Text Available Ethnobotanical investigations on local oilseed species in Burkina Faso revealed that oils from tree oilseeds are frequently used for food, cosmetics and traditional medicine by local people. To test the bio-preservative capacity, the effect of the oilseed extracts on the stabilization of Shea butter was evaluated. Levels of bioactive phyto-components were evaluated through several methods. Some aspects of the quality of oilcakes were evaluated based on their inhibitory capacity on the endogenous digestive enzymes of cattle. For fat stabilizing quality, the extract from Lannea microcarpa Engl. & K. Krause has showed the largest increase (91.47% in the Rancimat induction time (TIR of Shea butter. Using DPPH and FRAP methods for prevention or scavenging of free radicals, the results evidenced the highest activity with extracts of L. microcarpa. With respect to the feed quality of the oilcakes, the IC50 obtained with α-amylase and trypsin have showed that the ethanolic extracts of Pentadesma butyracea Sabine (1824 is less toxic for cattle. These results suggest that phenolic compounds extracted from these native oilseeds, especially those of Lannea microcarpa, can be used as biological antioxidants for bio-preservation of edible fats. In addition, the by-products of the oil-extraction can be valorized as nontoxic and protein-rich oilcakes for livestock feed.

  2. Optimal evolution models for quantum tomography

    International Nuclear Information System (INIS)

    Czerwiński, Artur


    The research presented in this article concerns the stroboscopic approach to quantum tomography, which is an area of science where quantum physics and linear algebra overlap. In this article we introduce the algebraic structure of the parametric-dependent quantum channels for 2-level and 3-level systems such that the generator of evolution corresponding with the Kraus operators has no degenerate eigenvalues. In such cases the index of cyclicity of the generator is equal to 1, which physically means that there exists one observable the measurement of which performed a sufficient number of times at distinct instants provides enough data to reconstruct the initial density matrix and, consequently, the trajectory of the state. The necessary conditions for the parameters and relations between them are introduced. The results presented in this paper seem to have considerable potential applications in experiments due to the fact that one can perform quantum tomography by conducting only one kind of measurement. Therefore, the analyzed evolution models can be considered optimal in the context of quantum tomography. Finally, we introduce some remarks concerning optimal evolution models in the case of n-dimensional Hilbert space. (paper)

  3. Multi-level opinion dynamics under bounded confidence. (United States)

    Kou, Gang; Zhao, Yiyi; Peng, Yi; Shi, Yong


    Opinion dynamics focuses on the opinion evolution in a social community. Recently, some models of continuous opinion dynamics under bounded confidence were proposed by Deffuant and Krause, et al. In the literature, agents were generally assumed to have a homogeneous confidence level. This paper proposes an extended model for a group of agents with heterogeneous confidence levels. First, a social differentiation theory is introduced and a social group is divided into opinion subgroups with distinct confidence levels. Second, a multi-level heterogeneous opinion formation model is formulated under the framework of bounded confidence. Finally, computer simulations are conducted to study the collective opinion evolution, focusing on three key factors: the fractions of heterogeneous agents, the initial opinions, and the group size. The simulation results demonstrate that the number of final opinions depends on the fraction of close-minded agents when the group size and the initial opinions are fixed; the final opinions converge more easily when the initial opinions are closer; and the number of final opinions can be approximately modeled by a linear increasing function of the group size and the increasing rate is the fraction of close-minded agents.

    Full Text Available Korff Krause, Carsten Schneider, Kai Jaquet, Karl-Heinz KuckHanseatic Heart Center Hamburg, Department of Cardiology, Asklepios Hospital St. Georg, Hamburg, GermanyAbstract: The recent identification of bone marrow-derived adult stem cells and other types of stem cells that could improve heart function after transplantation have raised high expectations. The basic mechanisms have been studied mostly in murine models. However, these experiments revealed controversial results on transdifferentiation vs transfusion of adult stem cells vs paracrine effects of these cells, which is still being debated. Moreover, the reproducibility of these results in precisely translated large animal models is still less well investigated. Despite these weaknesses results of several clinical trials including several hundreds of patients with ischemic heart disease have been published. However, there are no solid data showing that any of these approaches can regenerate human myocardium. Even the effectiveness of cell therapy in these approaches is doubtful. In future we need in this important field of regenerative medicine: i more experimental data in large animals that are closer to the anatomy and physiology of humans, including data on dose effects, comparison of different cell types and different delivery routes; ii a better understanding of the molecular mechanisms involved in the fate of transplanted cells; iii more intensive research on genuine regenerative medicine, applying genetic regulation and cell engineering.Keywords: stem cells, cardiovascular disease

  5. Co-Expression and Co-Localization of Cartilage Glycoproteins CHI3L1 and Lubricin in Osteoarthritic Cartilage: Morphological, Immunohistochemical and Gene Expression Profiles. (United States)

    Szychlinska, Marta Anna; Trovato, Francesca Maria; Di Rosa, Michelino; Malaguarnera, Lucia; Puzzo, Lidia; Leonardi, Rosy; Castrogiovanni, Paola; Musumeci, Giuseppe


    Osteoarthritis is the most common human arthritis characterized by degeneration of articular cartilage. Several studies reported that levels of human cartilage glycoprotein chitinase 3-like-1 (CHI3L1) are known as a potential marker for the activation of chondrocytes and the progression of Osteoarthritis (OA), whereas lubricin appears to be chondroprotective. The aim of this study was to investigate the co-expression and co-localization of CHI3L1 and lubricin in normal and osteoarthritic rat articular cartilage to correlate their modified expression to a specific grade of OA. Samples of normal and osteoarthritic rat articular cartilage were analyzed by the Kellgren-Lawrence OA severity scores, the Kraus' modified Mankin score and the Histopathology Osteoarthritis Research Society International (OARSI) system for histomorphometric evaluations, and through CHI3L1 and lubricin gene expression, immunohistochemistry and double immuno-staining analysis. The immunoexpression and the mRNA levels of lubricin increased in normal cartilage and decreased in OA cartilage (normal vs. OA, p < 0.01). By contrast, the immunoexpression and the mRNA levels of CHI3L1 increased in OA cartilage and decreased in normal cartilage (normal vs. OA, p < 0.01). Our findings are consistent with reports suggesting that these two glycoproteins are functionally associated with the development of OA and in particular with grade 2/3 of OA, suggesting that in the future they could be helpful to stage the severity and progression of the disease.

  6. Bolbophorus damnificus n. sp. (Digenea: Bolbophoridae) from the channel catfish Ictalurus punctatus and American white pelican Pelecanus erythrorhynchos in the USA based on life-cycle and molecular data. (United States)

    Overstreet, Robin M; Curran, Stephen S; Pote, Linda M; King, D Tommy; Blend, Charles K; Grater, Walter D


    The common pathogenic prodiplostomulum metacercaria in the flesh, mostly near the skin, of pond-produced channel catfish Ictalurus punctatus has been demonstrated to be Bolbophorus damnificus Overstreet & Curran n. sp. The catfish acquires the infection from the snail Planorbella trivolvis, the only known first intermediate host, and the species is perpetuated through the American white pelican Pelecanus erythrorhynchos, as confirmed by experimental infections with nestling and dewormed adult pelican specimens in conjunction with molecular data. It differs from the cryptic species Bolbophorus sp., also found concurrently in the American white pelican, by having eggs 123-129 microm rather than 100-112 microm long and consistent low values for nucleotide percentage sequence similarity comparing COI, ITS 1/2, 18S rRNA and 28S rRNA fragments. Bolbophorus sp. is comparable but most likely distinct from B. confusus (Kraus, 1914), which occurs in Europe and has eggs 90-102 microm long. Its intermediate hosts were not demonstrated. The adults of neither of the confirmed North American species of Bolbophorus were encountered in any bird other than a pelican, although several shore birds feed on infected catfish, and B. damnificus can survive but not mature when protected in the mouse abdominal cavity. B. ictaluri (Haderlie, 1953) Overstreet & Curran n. comb., a species different from B. damnificus, is considered a species inquirenda.

  7. Duality quantum algorithm efficiently simulates open quantum systems (United States)

    Wei, Shi-Jie; Ruan, Dong; Long, Gui-Lu


    Because of inevitable coupling with the environment, nearly all practical quantum systems are open system, where the evolution is not necessarily unitary. In this paper, we propose a duality quantum algorithm for simulating Hamiltonian evolution of an open quantum system. In contrast to unitary evolution in a usual quantum computer, the evolution operator in a duality quantum computer is a linear combination of unitary operators. In this duality quantum algorithm, the time evolution of the open quantum system is realized by using Kraus operators which is naturally implemented in duality quantum computer. This duality quantum algorithm has two distinct advantages compared to existing quantum simulation algorithms with unitary evolution operations. Firstly, the query complexity of the algorithm is O(d3) in contrast to O(d4) in existing unitary simulation algorithm, where d is the dimension of the open quantum system. Secondly, By using a truncated Taylor series of the evolution operators, this duality quantum algorithm provides an exponential improvement in precision compared with previous unitary simulation algorithm.

    Full Text Available Albuca crispa is a new species of section Falconera series Trianthera with crispulate leaves from the Great Karoo, known  at least since 1947 but overlooked until now. A second new species. A grandis. from the southwestern Cape was previously included in  A. fragrans Jacq. (section  Falconera series  Falconera. It is a robust species that flowers in winter and early spring and the styles are rugulose with ± isodiametric epidermal cells, unlike typical  A. fragrans which is a more slender species flowering in early summer and with derived, smooth styles with fusiform epidermal cells. The recent discovery of a flowering population matching the type of A. albucoides (Aiton J.C.Manning & Goldblatt (subgenus Osmyne allows for a full description and illustration of this poorly know n and taxonomically neglected species that has often been included in A. suaveolens (Jacq.

  10. The appropriate or optimal tempo for music: a comparison between non-musicians and musicians. (United States)

    Quinn, Sandra; Watt, Roger


    Musicians have enhanced skills that result from intensive training. Whilst musicians show enhanced auditory capabilities (Kraus and Chandrasekaran, 2010 Nature Reviews Neuroscience 11 599-605), non-musicians demonstrate an ability to perform musical tasks (eg listening, dancing, and singing). Non-musicians can also undertake tasks that would normally be reserved for musicians. For example, non-musicians can perceive optimal tempi (ie an appropriate speed) for music (Quinn and Watt, 2006 Perception 35 267-280; Quinn and Watt, 2012 Perception 41 236-238; Quinn et al, 2012 Journal of the Acoustical Society of America 131 3595-3598). This suggests that formalised musical training is not a prerequisite for developing a sense of the tempo that sounds right for a melody. The current studies examine this issue and compare the tempo that musicians choose to perform unfamiliar melodies with the tempo that non-musicians perceive to be optimal for the same melodies. The results demonstrate that the perceived optimal tempo is similar to the performed tempo.

  11. Continuous Opinion Dynamics Under Bounded Confidence:. a Survey (United States)

    Lorenz, Jan

    Models of continuous opinion dynamics under bounded confidence have been presented independently by Krause and Hegselmann and by Deffuant et al. in 2000. They have raised a fair amount of attention in the communities of social simulation, sociophysics and complexity science. The researchers working on it come from disciplines such as physics, mathematics, computer science, social psychology and philosophy. In these models agents hold continuous opinions which they can gradually adjust if they hear the opinions of others. The idea of bounded confidence is that agents only interact if they are close in opinion to each other. Usually, the models are analyzed with agent-based simulations in a Monte Carlo style, but they can also be reformulated on the agent's density in the opinion space in a master equation style. The contribution of this survey is fourfold. First, it will present the agent-based and density-based modeling frameworks including the cases of multidimensional opinions and heterogeneous bounds of confidence. Second, it will give the bifurcation diagrams of cluster configuration in the homogeneous model with uniformly distributed initial opinions. Third, it will review the several extensions and the evolving phenomena which have been studied so far, and fourth it will state some open questions.

The influence of nano-and micro- particle size of SiO2 on physical and mechanical properties, as well as effectiveness volume ratio of filiers in NBR-CSM polymer matrix at 300% elongation was tested using Einstein-Quth-Gold equation. The Kraus equation for swelling test of NBR-CSM polymer matrix containing nano- and micro- particle size of SiO2. Test results have shown that a greater interaction of nano-particie size of SiO2 with NBR-CSM polymer matrix, and possible chemical bonding, than the one of micro-silica was a consequence of a greater contact area. This results in better physical and mechanical properties.

  13. Yoga Practice Increases Minimum Muscular Fitness in Children with Visual Impairment. (United States)

    Mohanty, Soubhagyalaxmi; Venkata Ramana Murty, Peri; Pradhan, Balaram; Hankey, Alex


    Muscle strength, a component for balance, gait and functional mobility is vital for children with visual impairment. Yoga has frequently been demonstrated to improve physical and mental fitness in children. This study aimed to assess the effect of 16 weeks yoga training on muscular fitness in children with visual impairment. This was a wait-listed two-armed-matched case-control study. Eighty (41 yoga, 39 control) visual impairment students of both genders aged 9-16 years matched on age, gender and degree of blindness were assessed at pre, mid (after 8 weeks) and post (after 16 weeks) yoga intervention using the Kraus-Weber test. The percentage of students passed in yoga group were 12.2%, 43.9% and 68.3% whereas percentages in the control group were 23.1%, 30.8% and 30.8% in pre, mid, and post tests respectively. McNemar test showed significant differences between pre and mid, mid and post in the yoga group while those parameters were not significantly different in the control group. Yoga therapy seemed to have considerable benefits for the children's muscular fitness. The study suggests that yoga have considerable benefits for improvement of fitness level in children with visual impairment and may be recommended as and effective, alternative, inexpensive low risk training activity option for them.

  14. Herschel Observations of the Pre-Collapse Phase of Star Formation (United States)

    Di Francesco, J.


    Stars form after compact gas cores condense out of larger molecular clouds and collapse. How these cores themselves form has been difficult to observe, given the limitations of detecting from the ground faint, diffuse sub-structure in clouds (e.g., clumps and filaments). With its sensitive, spaceborne instrumentation, however, Herschel has now detected these structures in numerous clouds out to several kiloparsecs from their continuum emission. Indeed, the continuum data from PACS and SPIRE are revolutionizing our understanding of the environments from which cores themselves arise. In this review, we will summarize the recent results of several Herschel Key Programmes whose goals include better physical understanding of these environments. The specific programmes with prestellar core targets include the Herschel Gould Belt Survey (GBS; PI: Ph. André), the Herschel OB Young Star survey (HOBYS; PI: F. Motte), Galactic Cold Cores (GCC; PI: M. Juvela), the Earliest Phases of Star Formation (EPoS; PI: O. Krause), and the Herschel Galactic Plane Survey (HiGAL; PI: S. Molinari). We show in general that filaments are found on many scales throughout the Galaxy, and are a key aspect to the pre-collapse phase of star formation not previously appreciated before Herschel. In addition, the continuum data are providing new direct probes of the thermal and density structures of pre-collapse star-forming objects.

  15. Use of 3D-computed tomography angiography for planning the surgical removal of pineal region meningiomas using Poppen's approach: a report of ten cases and a literature review

    Li Ye


    Full Text Available Abstract Background There are several treatment approaches for pineal region meningiomas, such as Poppen's approach, Krause's approach and combinations of the two approaches. We present our experience with the use of 3D-computed tomography angiography for planning the surgical removal of pineal region meningiomas using a suboccipital transtentorial approach (Poppen's approach and evaluate the role of Poppen's approach. Methods During the period from January 2005 to June 2010, ten patients presented to us with pineal region meningioma. MRI was routinely used to define the tumor size, position, and its relevant complications while 3D-CTA was applied to define the blood supply of the tumor and the venous complex (VC shift before operations. Most of the meningiomas had developed at both sides of the tentorial plane and extended laterally with typical characteristics of a pineal region tumor. Results All tumors were completely removed surgically without any injury to the VC. Postoperative intracranial infection occurred in one case who recovered after antibiotics were given. Postoperative intraventricular hemorrhage and pneumocephalus were found in one case, but fully recovered after conservative treatment. In the nine cases of concurrent hydrocephalus, this was gradually relieved in eight patients and the single case that became aggravated was successfully treated with ventriculoperitoneal shunt. Moreover, the follow-up MRI examinations did not indicate any recurrence of the meningiomas. Conclusion We found that the use of Poppen's approach is strongly supported for the successful removal of pineal region meningiomas without serious complications.

    Bauer, Bruno


    Full Text Available Since 2007 the university library at the Medical University Vienna runs a provenance research project. Books, stolen between 1938 and 1945, were acquired by at that time discrete libraries at institutions and clinics of the former medical faculty at Vienna University. A systematic survey of the now centralised book collection should bring to light these misgotten book acquisitions. Aim of the project is to document such cases and to restitute books to their lawful owners or their legal successors. Until Novemver 2008 about 80,000 volumes were scrutinised directly at the shelves by so-called autopsy. So far about 200 definitely stolen books and approximately 1800 suspicious books were dedected. This paper describes the initial position, method and hitherto existing results of the provenance research project.

  17. Ancilla-assisted sequential approximation of nonlocal unitary operations (United States)

    Saberi, Hamed


    We consider the recently proposed “no-go” theorem of Lamata [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.101.180506 101, 180506 (2008)] on the impossibility of sequential implementation of global unitary operations with the aid of an itinerant ancillary system and view the claim within the language of Kraus representation. By virtue of an extremely useful tool for analyzing entanglement properties of quantum operations, namely, operator-Schmidt decomposition, we provide alternative proof to the no-go theorem and also study the role of initial correlations between the qubits and ancilla in sequential preparation of unitary entanglers. Despite the negative response from the no-go theorem, we demonstrate explicitly how the matrix-product operator (MPO) formalism provides a flexible structure to develop protocols for sequential implementation of such entanglers with an optimal fidelity. The proposed numerical technique, which we call variational matrix-product operator (VMPO), offers a computationally efficient tool for characterizing the “globalness” and entangling capabilities of nonlocal unitary operations.

    Normal histologic architecture of acetabular labrum, regarding presence of Free Nerve Endings (FNEs) and Nerve End Organs (NEOs) has been four times described. Nevertheless, elderly cadaveric specimens and individuals were recruited, leading to considerably high unreliability probability due to microscopic degenerative alterations. Aim of this paper is to analyze distribution pattern of FNEs and NEOs in acetabular labra of healthy middle-aged individuals, configuring thus more reliably acetabular labrum microscopic profile. Six patients with middle age 52 ± 2.5 years were enrolled in this study. Injury of acetabular labrum and normal hip radiograph were present in all cases. Patients were all subjected to successful hip hemi-arthroplasty and derived acetabular labra were subsequently histologically processed and observed under a compound microscope. FNEs and NEOs were detected in all specimens. All types of NEOs were identified, including Paccini, Golgi-Mazzoni, Ruffini and Krause corpuscles. FNEs and NEOs were both in ventral part and in chondral side of labrum predominantly detected. FNEs and NEOs presence was greater in ventral side of labrum, being thus in partial agreement with previous studies results. Further study is required, in order to elucidate the exact acetabular labrum normal microscopic anatomy. IV.

  19. Coherifying quantum channels (United States)

    Korzekwa, Kamil; Czachórski, Stanisław; Puchała, Zbigniew; Życzkowski, Karol


    Is it always possible to explain random stochastic transitions between states of a finite-dimensional system as arising from the deterministic quantum evolution of the system? If not, then what is the minimal amount of randomness required by quantum theory to explain a given stochastic process? Here, we address this problem by studying possible coherifications of a quantum channel Φ, i.e., we look for channels {{{Φ }}}{ \\mathcal C } that induce the same classical transitions T, but are ‘more coherent’. To quantify the coherence of a channel Φ we measure the coherence of the corresponding Jamiołkowski state J Φ. We show that the classical transition matrix T can be coherified to reversible unitary dynamics if and only if T is unistochastic. Otherwise the Jamiołkowski state {J}{{Φ }}{ \\mathcal C } of the optimally coherified channel is mixed, and the dynamics must necessarily be irreversible. To assess the extent to which an optimal process {{{Φ }}}{ \\mathcal C } is indeterministic we find explicit bounds on the entropy and purity of {J}{{Φ }}{ \\mathcal C }, and relate the latter to the unitarity of {{{Φ }}}{ \\mathcal C }. We also find optimal coherifications for several classes of channels, including all one-qubit channels. Finally, we provide a non-optimal coherification procedure that works for an arbitrary channel Φ and reduces its rank (the minimal number of required Kraus operators) from {d}2 to d.

  20. Classifying and segmenting microscopy images with deep multiple instance learning. (United States)

    Kraus, Oren Z; Ba, Jimmy Lei; Frey, Brendan J


    High-content screening (HCS) technologies have enabled large scale imaging experiments for studying cell biology and for drug screening. These systems produce hundreds of thousands of microscopy images per day and their utility depends on automated image analysis. Recently, deep learning approaches that learn feature representations directly from pixel intensity values have dominated object recognition challenges. These tasks typically have a single centered object per image and existing models are not directly applicable to microscopy datasets. Here we develop an approach that combines deep convolutional neural networks (CNNs) with multiple instance learning (MIL) in order to classify and segment microscopy images using only whole image level annotations. We introduce a new neural network architecture that uses MIL to simultaneously classify and segment microscopy images with populations of cells. We base our approach on the similarity between the aggregation function used in MIL and pooling layers used in CNNs. To facilitate aggregating across large numbers of instances in CNN feature maps we present the Noisy-AND pooling function, a new MIL operator that is robust to outliers. Combining CNNs with MIL enables training CNNs using whole microscopy images with image level labels. We show that training end-to-end MIL CNNs outperforms several previous methods on both mammalian and yeast datasets without requiring any segmentation steps.

  1. Landau–Zener evolution under weak measurement: manifestation of the Zeno effect under diabatic and adiabatic measurement protocols

    International Nuclear Information System (INIS)

    Novelli, Anna; Belzig, Wolfgang; Nitzan, Abraham


    The time evolution and the asymptotic outcome of a Landau–Zener–Stueckelberg–Majorana (LZ) process under continuous weak non-selective measurement is analyzed. We compare two measurement protocols in which the populations of either the adiabatic or the non-adiabatic levels are (continuously and weakly) monitored. The weak measurement formalism, described using a Gaussian Kraus operator, leads to a time evolution characterized by a Markovian dephasing process, which, in the non-adiabatic measurement protocol is similar to earlier studies of LZ dynamics in a dephasing environment. Casting the problem in the language of measurement theory makes it possible for us to compare diabatic and adiabatic measurement scenarios, to consider engineered dephasing as a control device and to examine the manifestation of the Zeno effect under the different measurement protocols. In particular, under measurement of the non-adiabatic populations, the Zeno effect is manifested not as a freezing of the measured system in its initial state, but rather as an approach to equal asymptotic populations of the two diabatic states. This behavior can be traced to the way by which the weak measurement formalism behaves in the strong measurement limit, with a built-in relationship between measurement time and strength. (paper)

  2. Liquid electrolytes based on new lithium conductive imidazole salts

    Niedzicki, L.; Kasprzyk, M.; Kuziak, K.; Zukowska, G.Z.; Marcinek, M.; Wieczorek, W. [Department of Chemistry, Warsaw University of Technology, Noakowskiego 3, 00-664 Warsaw (Poland); Armand, M. [LRCS, University de Picardie Jules Verne, UMR 6007 CNRS, 33 rue de Saint-Leu, 80039 Amiens (France)


    In the present paper new generation of imidazole-derived lithium salts (LiTDI - lithium 4,5-dicyano-2-(trifluoromethyl)imidazolide, LiPDI - lithium 4,5-dicyano-2-(pentafluoroethyl)imidazolide and LiHDI - lithium 4,5-dicyano-2-(n-heptafluoropropyl)imidazolide) applied in a model liquid electrolyte, with propylene carbonate used as a solvent, is described. Room temperature ionic conductivities measured by Impedance Spectroscopy are as high as 10{sup -2} to 10{sup -3} S cm{sup -1} for the 0.1-1 mol dm{sup -3} salt concentration range. Lithium cation transference numbers calculated using the Bruce-Vincent method exceed 0.4 at salt concentration equal to 1 mol dm{sup -3}. Interface resistance measurements showed good stability at high - 0.5 mol dm{sup -3} or low - 0.01 mol dm{sup -3} salt concentrations. Ionic associations were estimated using Fuoss-Kraus semiempirical method revealing relatively low association rates. The effect of anion structure on ionic interactions and electrochemical characteristics of the studied electrolytes is discussed. (author)

  3. A Translational Model of Research-Practice Integration (United States)

    Vivian, Dina; Hershenberg, Rachel; Teachman, Bethany A.; Drabick, Deborah A. G.; Goldfried, Marvin R.; Wolfe, Barry


    We propose a four-level, recursive Research-Practice Integration framework as a heuristic to (a) integrate and reflect on the articles in this Special Section as contributing to a bidirectional bridge between research and practice, and (b) consider additional opportunities to address the research–practice gap. Level 1 addresses Treatment Validation studies and includes an article by Lochman and colleagues concerning the programmatic adaptation, implementation, and dissemination of the empirically supported Coping Power treatment program for youth aggression. Level 2 translation, Training in Evidence-Based Practice, includes a paper by Hershenberg, Drabick, and Vivian, which focuses on the critical role that predoctoral training plays in bridging the research–practice gap. Level 3 addresses the Assessment of Clinical Utility and Feedback to Research aspects of translation. The articles by Lambert and Youn, Kraus, and Castonguay illustrate the use of commercial outcome packages that enable psychotherapists to integrate ongoing client assessment, thus enhancing the effectiveness of treatment implementation and providing data that can be fed back to researchers. Lastly, Level 4 translation, the Cross-Level Integrative Research and Communication, concerns research efforts that integrate data from clinical practice and all other levels of translation, as well as communication efforts among all stakeholders, such as researchers, psychotherapists, and clients. Using a two-chair technique as a framework for his discussion, Wolfe's article depicts the struggle inherent in research–practice integration efforts and proposes a rapprochement that highlights advancements in the field.

  4. Opinion dynamics in activity-driven networks (United States)

    Li, Dandan; Han, Dun; Ma, Jing; Sun, Mei; Tian, Lixin; Khouw, Timothy; Stanley, H. Eugene


    Social interaction between individuals constantly affects the development of their personal opinions. Previous models such as the Deffuant model and the Hegselmann-Krause (HK) model have assumed that individuals only update their opinions after interacting with neighbors whose opinions are similar to their own. However, people are capable of communicating widely with all of their neighbors to gather their ideas and opinions, even if they encounter a number of opposing attitudes. We propose a model in which agents listen to the opinions of all their neighbors. Continuous opinion dynamics are investigated in activity-driven networks with a tolerance threshold. We study how the initial opinion distribution, tolerance threshold, opinion-updating speed, and activity rate affect the evolution of opinion. We find that when the initial fraction of positive opinion is small, all opinions become negative by the end of the simulation. As the initial fraction of positive opinions rises above a certain value —about 0.45— the final fraction of positive opinions sharply increases and eventually equals 1. Increased tolerance threshold δ is found to lead to a more varied final opinion distribution. We also find that if the negative opinion has an initial advantage, the final fraction of negative opinion increases and reaches its peak as the updating speed λ approaches 0.5. Finally we show that the lower the activity rate of individuals, the greater the fluctuation range of their opinions.

    Francisco Rüdiger


    Full Text Available As transformações por que passou a imprensa por volta de 1900 deram origem a uma reavaliação de seu significado e bases teóricas por parte de seus intérpretes liberais. O colapso do jornalismo político e doutrinário delas resultante foi, de início, objeto de assimilação, via a reestruturação de suas antigas teorias. Depois de 1918, porém, sua agenda de discussões migrou do campo da formação da opinião pública para o da manipulação da consciência das massas. As teorias liberais sofreram um eclipse, que subordinou a velha figura da imprensa ao novo conceito de propaganda. Este artigo relata e avalia as peculiaridades históricas desse processo, analisando as ideias de Frank Taylor, Emil Löbl, Wilhelm Bauer, Karl Kraus e Henry Mencken.

  7. Encapsulated sensory corpuscle in the mucosa of human vocal cord: an electron microscope study. (United States)

    Nagai, T


    Encapsulated sensory corpuscles of the Krause type were found in the mucosa of surgically removed human vocal cords. The corpuscles were ellipsoidal structures of about 30 to 50 micrometers and were located beneath the free edge in the mid-region along the intermembranous part. They contained a number of varicose nerve endings and lamellar cells. The lamellar cells had thin cytoplasmic lamellae which contained numerous cytoplasmic filaments and were interposed between the nerve endings. Attachment devices were frequently noted between the cytoplasmic lamellae and between the lamellae and nerve endings. Half-desmosomes were also noted along the plasma membrane of the lamellar cells. The intercellular space was filled with amorphous electron lucent material and contained a few collagen fibrils. Ladder-like filamentous structures were frequently encountered in the intercellular space. The location of the corpuscles at the free edge of the vocal cords suggests that the endings may receive the bilateral touch of the vibrating part of the cords in order to give sensory information for the control of the movement of the cords in phonation.

  8. Light and electron microscopy of contacts between primary afferent fibres and neurones with axons ascending the dorsal columns of the feline spinal cord. (United States)

    Maxwell, D J; Koerber, H R; Bannatyne, B A


    In addition to primary afferent fibres, the dorsal columns of the cat spinal cord contain ascending second-order axons which project to the dorsal column nuclei. The aim of the present study was to obtain morphological evidence that certain primary afferent axons form monosynaptic contacts with cells of origin of this postsynaptic dorsal column pathway. In ten adult cats, neurones with axons ascending the dorsal columns were retrogradely labelled with horseradish peroxidase using a pellet implantation method in the thoracic dorsal columns. In the lumbosacral regions of the same animals, primary afferent fibres were labelled intra-axonally with ionophoretic application of horseradish peroxidase. Tissue containing labelled axons was prepared for light and combined light and electron microscopy. Ultrastructural examination demonstrated that slowly adapting (Type I), hair follicle, Pacinian corpuscle and group Ia muscle spindle afferents formed monosynaptic contacts with labelled cells and light microscopical analysis suggested that they also received monosynaptic input from rapidly adapting (Krause) afferents. This evidence suggests that sensory information from large-diameter cutaneous and muscle spindle afferent fibres is conveyed disynaptically via the postsynaptic dorsal column pathway to the dorsal column nuclei. Some of the input to this pathway is probably modified in the spinal cord as the majority of primary afferent boutons forming monosynaptic contacts were postsynaptic to other axon terminals. The postsynaptic dorsal column system appears to constitute a major somatosensory pathway in the cat.

    Full Text Available The crystal structure of the title salt, C13H19Cl2N2+·Cl−, has been reported previously [Homrighausen & Krause Bauer (2002. Acta Cryst. E58, o1395–o1396] based on room-temperature data, where it was found to contain a disordered chloropropyl group. We now present the structure at 100 K in which the chloropropyl group is ordered. The piperazine ring adopts a chair conformation with the exocyclic N—C bonds in equatorial orientations. The dihedral angle between the piperazine ring (all atoms and the benzene ring is 28.47 (5°. The chloropropyl group has an extended conformation [N—C—C—C = −177.25 (8 ° and C—C—C—Cl = 174.23 (7°]. In the crystal, charge-assisted N—H...Cl hydrogen bonds link the cation and anion into ion pairs. Numerous weak C—H...Cl interactions link the ion pairs into a three-dimensional network. Short Cl...Cl contacts [3.2419 (4 Å] are also observed.

  10. Differential vulnerability of 3 rapidly conducting somatosensory pathways in the dog with vitamin B6 neuropathy. (United States)

    Schaeppi, U; Krinke, G


    In anesthetized dogs with chronically implanted cortical electrodes somatic sensory-evoked potentials (SEPs) were produced by electrical stimulation at neural, muscular or cutaneous sites of the contralateral hind leg. Stimulation of the tibial nerve at the calcaneus or of the short flexor muscles of the hind paw caused SEPs having characteristics following activation of rapidly conducting afferents from muscle spindles. Stimulation of the glabrous skin of the central pad resulted in SEPs arriving after a more protracted latency evidently related to activation of afferents from Merkel cells, Krause and Pacinian corpuscles known to be located at these sites. Stimulation of the hairy skin from the dorsal surface of the hindpaw produced a further type of SEP presumably resulting from activation of afferents from receptors of tylotrich hair follicles. Vitamin B6-induced neuropathy involves the selective degeneration of the largest neurons in the spinal ganglia and of associated long peripheral and central neurites performing rapid impulse transmission. In the course of vitamin B6 neuropathy the relatively slow impulse transmission following stimulation of the central pad was more severely impaired than the faster one after activation of afferents from muscle spindles or receptors from hair follicles. This allows us to conclude that in the dog afferents from the glabrous skin of the central pad conduct centrally via the dorsal columns, susceptible to vitamin B6 intoxication, while muscle and hair receptor afferents ascend in the dorsal spinocerebellar and spinocervical tract, respectively, which are vitamin B6 resistant.

  12. Zero-error classical channel capacity and simulation cost assisted by quantum non-signalling correlations

    Energy Technology Data Exchange (ETDEWEB)

    Winter, Andreas [Universitat Autonoma de Barcelona (Spain)


    We describe quantum non-signalling correlations as two-input and two-output completely positive and trace preserving maps with linear constraints determining non-signalling. We then study the one-shot zero-error classical capacity of a quantum channel assisted by quantum non-signalling correlations, and the reverse problem of simulation. Both lead to simple semidefinite programmings (SDPs) whose solutions can be given in terms of the conditional min-entropies and depend only on the Kraus operator space of the channel. In particular, we show that the asymptotic zero-error classical simulation cost is precisely the conditional min-entropy of the Choi-Jamiolkowski matrix of the given channel. The asymptotic zero-error classical capacity is given by the regularization of a sequence of SDPs, and generally has no simple form. Interestingly, for the class of classical-quantum channels, we show that the asymptotic capacity is reduced to the solution of a rather simple SDP, which coincides with a quantum version of the fractional packing number suggested by Aram Harrow. This further gives an operational interpretation of the celebrated Lovasz number of a classical graph as the zero-error classical capacity of the graph assisted by quantum non-signalling correlations.

    We construct concrete counterterms of the Balasubramanian-Kraus type for Einstein-scalar theories with designer gravity boundary conditions in AdS{sub 4}, so that the total action is finite on-shell and satisfy a well defined variational principle. We focus on scalar fields with the conformal mass m{sup 2}=−2l{sup −2} and show that the holographic mass matches the Hamiltonian mass for any boundary conditions. We compute the trace anomaly of the dual field theory in the generic case, as well as when there exist logarithmic branches of non-linear origin. As expected, the anomaly vanishes for the boundary conditions that are AdS invariant. When the anomaly does not vanish, the dual stress tensor describes a thermal gas with an equation of state related to the boundary conditions of the scalar field. In the case of a vanishing anomaly, we recover the dual theory of a massless thermal gas. As an application of the formalism, we consider a general family of exact hairy black hole solutions that, for some particular values of the parameters in the moduli potential, contains solutions of four-dimensional gauged N=8 supergravity and its ω-deformation. Using the AdS/CFT duality dictionary, they correspond to triple trace deformations of the dual field theory.

  14. Sora rail studies on the Patuxent River, Maryland (United States)

    Haramis, M.; Kearns, G.D.


    College. During 1996-97 we developed a successful radio transmitter attachment technique to secure 1.8g radio transmitters over the synsacrum of migrant soras. We modified Rappole and Tipton's (1991) leg-loop attachment method by addition of a waist loop to prevent soras from slipping transmitters over their short tails. Thin gauge (0.6 mm) elastic thread proved ideal for attachment and allowed for girth expansion associated with fattening during stopover. Sixty instrumented soras have been monitored in two years of study from early September until early November. Only a single mortality was recorded and 41 (68%) were confIrmed and another 13 (total 90%) were believed to have migrated from the study area. Only a single bird slipped a radio transmitter. Most birds demonstrated a sedentary nature in the marsh throughout stopover. Average length of stay was 44 days in 1997 (n=29) with peak departure occurring 20-24 October. Departing migrants were detected using a receiver/data-logger monitoring system placed 4 miles down river from the study site. Thirty-six of 37 (97%) soras departed in a 2-hour window of time, beginning 1 hour after sunset. Departure was synchronized with cold fronts on clear, starlit nights. Twenty-five soras were monitored on migration from 8 km to as far away as 770 km. Findings indicate migration flight speeds of 40 to 50 mph and a direct southward orientation from the study site at least until contact with the Atlantic Ocean west of Cape Lookout, North Carolina. We also attempted to monitor passage of migrant soras radio tagged at Iroquois National Wildlife Refuge in western New York by biologist Soch Lor. None were recorded passing a monitoring unit at Haldeman Island in the middle of the Susquehanna River 10 miles north of Harrisburg, Pennsylvania. This further corroborates our findings that when migrating overland, soras move in a direct southward orientation and are not following land features such as major rivers

  15. Synthesis of data from high-frequency nutrient and associated biogeochemical monitoring for the Sacramento–San Joaquin Delta, northern California (United States)

    Downing, Bryan D.; Bergamaschi, Brian A.; Kraus, Tamara E.C.


    Executive SummaryThis report is the second in a series of three reports that provide information about high-frequency (HF) nutrient and biogeochemical monitoring in the Sacramento–San Joaquin Delta of northern California (Delta). The purpose of this report is to synthesize the data available from a nutrient and water-quality HF (about every 15 minutes) monitoring network operated by the U.S. Geological Survey in the northern Delta. In this report, we describe the network and focus on the purpose of each station. We then present and discuss the available data, at various timescales—first at the monthly, seasonal, and inter-annual timescales, and second, for comparison, at the tidal and event timescales. As expected, we determined that there is substantial variability in nitrate-N concentrations at short timescales within hours, but also significant variability at longer timescales such as months or years. Resolving this variability is made possible by the HF data, with the largest variability caused by storms, tides, and diel biological processes. Given this large temporal variability, calculations of cumulative nutrient fluxes (for example, daily, monthly, or annual loads) is difficult without HF data. For example, in the Cache Slough, calculation of the annual load without the tidal variability resulted in a 30 percent underestimation of the true annual load value. We conclude that HF measurements are important for accurate determination of fluxes and loads in tidal environments, but, more importantly, provide important insights into processes and rates of nutrient cycling.This report, along with the other two reports of this series (Bergamaschi and others, 2017; Kraus, Bergamaschi, and others, 2017), was drafted in cooperation with the Delta Regional Monitoring Program to help scientists, managers, and planners understand how HF data improve our understanding of nutrient sources and sinks, drivers, and effects in the Delta. The first report in the series

    Bergamaschi, Brian A.; Downing, Bryan D.; Kraus, Tamara E.C.; Pellerin, Brian A.


    Executive SummaryThis report is the third in a series of three reports that provide information about how high-frequency (HF) nutrient monitoring may be used to assess nutrient inputs and dynamics in the Sacramento–San Joaquin Delta, California (Delta). The purpose of this report is to provide the background, principles, and considerations for designing an HF nutrient-monitoring network for the Delta to address high-priority, nutrient-management questions. The report starts with discussion of the high-priority management questions to be addressed, continues through discussion of the questions and considerations that place demands and constraints on network design, discusses the principles applicable to network design, and concludes with the presentation of three example nutrient-monitoring network designs for the Delta. For three example network designs, we assess how they would address high-priority questions that have been identified by the Delta Regional Monitoring Program (Delta Regional Monitoring Program Technical Advisory Committee, 2015).This report, along with the other two reports of this series (Kraus and others, 2017; Downing and others, 2017), was drafted in cooperation with the Delta Regional Monitoring Program to help scientists, managers, and planners understand how HF data improve our understanding of nutrient sources and sinks, drivers, and effects in the Delta. The first report in the series (Kraus and others, 2017) provides an introduction to the reasons for and fundamental concepts behind using HF monitoring measurements, including a brief summary of nutrient status and trends in the Delta and an extensive literature review showing how and where other research and monitoring programs have used HF monitoring to improve our understanding of nutrient cycling. The report covers the various technologies available for HF nutrient monitoring and presents the different ways HF monitoring instrumentation may be used for both fixed station and spatial

  17. Un taccuino a forma di strada. Su "Einbahnstrasse" di Walter Benjamin

    Directory of Open Access Journals (Sweden)

    Pier Giovanni Adamo


    Full Text Available La poetica di F. Schlegel ha realizzato una storicizzazione della teoria dei generi letterari sostituendo alla dicotomia del classicismo tra forma e contenuto una distinzione tra forma e spirito, secondo cui i materiali linguistico-tematici rappresentano i precipitati di quest’ultimo. Riprendendo questa intuizione di P. Szondi, potremmo affermare che, nella modernità letteraria, l’ibridazione è il processo di transizione dei materiali attraverso le forme. Un’opera tanto esemplare quanto strutturalmente rilevante, nell’orizzonte dell’ibridazione, è Einbahnstraße di Walter Benjamin, dove i materiali più disparati sono combinati a modellare una forma innovativa. Vi si mescolano stilemi della poesia in prosa, narrazione diaristica, (antimetodo surrealista, satira e intuizioni filosofiche. L’unicità, d’altra parte, risiede innanzitutto nell’essenza metacritica del procedimento organizzativo del libro: il frammentismo sistematico è un’applicazione pratica della teoria allegorica del montaggio, descritta nell’Ursprung des deutschen Trauerspiels. Il saggio si propone di leggere il testo come «un taccuino a forma di strada», anche per indagarne il valore di prologo al Passagenwerk, nato dall’avida lettura del Paysan de Paris di Aragon: istituisce un confronto per rilevare, nell’affinità di fondo, la  diversità di approccio tra il pensatore tedesco e il surrealismo, distinguendo tecniche di assemblaggio e ruolo dell’immaginario nell’uso di pubblicità e altri oggetti metropolitani. L’intenzione di una simile analisi di Einbahnstraße è dimostrare che Benjamin combina modelli letterari (Baudelaire, Proust, Kraus su tutti con i nuovi linguaggi artistici e le strategie discorsive della stampa per creare un’«immagine dialettica» dell’esistenza nel XX secolo.Friedrich Schlegel’s poetics realized a historicisation of literary genres theory by replacing classicist dichotomy between form and content with a

    Beegle-Krause, C. J.; Boyer, T.; Murray, D.


    , previous research and modeling were combined to tell the story of the DWH MC 252 from the subsurface perspective. The Comprehensive Deepwater Oil and Gas model (CDOG, Yapa and Xie, 2005), and the General NOAA Operational Modeling Environment (GNOME, Beegle-Krause, 1999) were used with the NOAA Gulf of Mexico Model nowcast/forecast model to understand the 3D evolution of the subsurface spill.

    Full Text Available We explored the short-term adjustment in photochemical efficiency (Fv /Fm in adult and young leaves of the understory neotropical shrub Psychotria limonensis Krause (Rubiaceaein response to rapid changes in the light environment.Leaves were collected from 20 individual plants growing under sun and shade conditions on Gigante Peninsula,Barro Colorado Natural Monument (Republic of Panama,during the wet season of 1996. Leaves were distributed in four sequences of light treatments (AB leaves were expanded under sun and were transferred to shade,BA leaves experienced the opposite transfer,and the controls AA and BB leaves that were expanded and maintained under sun or shade conditions.Adult and young leaves did not differ in overall photochemical efficiency.Instead,differences were found among light environments,for which leaves transferred from shade to sun showed the lowest F v /F m ratios.There was no relationship between photochemical efficiency and leaf temperature.In P.limonensis,understory plants are susceptible of photoinhibition independently of the leaf ontogenetic stage.The approach utilized in this experiment allowed the rapid exploration of this capacity, and could be applied to poorly studied understory species.

    Kraus, George A.


    The overall objective of this proposal is to enable Iowa State University to establish a Center that enjoys world-class stature and eventually enhances the economy through the transfer of innovation from the laboratory to the marketplace. The funds have been used to support experimental proposals from interdisciplinary research teams in areas related to catalysis and green chemistry. Specific focus areas included: • Catalytic conversion of renewable natural resources to industrial materials • Development of new catalysts for the oxidation or reduction of commodity chemicals • Use of enzymes and microorganisms in biocatalysis • Development of new, environmentally friendly reactions of industrial importance These focus areas intersect with barriers from the MYTP draft document. Specifically, section Processing and Conversion has a list of bulleted items under Improved Chemical Conversions that includes new hydrogenation catalysts, milder oxidation catalysts, new catalysts for dehydration and selective bond cleavage catalysts. Specifically, the four sections are: 1. Catalyst development (7.4.12.A) 2. Conversion of glycerol (7.4.12.B) 3. Conversion of biodiesel (7.4.12.C) 4. Glucose from starch (7.4.12.D) All funded projects are part of a soybean or corn biorefinery. Two funded projects that have made significant progress toward goals of the MYTP draft document are: Catalysts to convert feedstocks with high fatty acid content to biodiesel (Kraus, Lin, Verkade) and Conversion of Glycerol into 1,3-Propanediol (Lin, Kraus). Currently, biodiesel is prepared using homogeneous base catalysis. However, as producers look for feedstocks other than soybean oil, such as waste restaurant oils and rendered animal fats, they have observed a large amount of free fatty acids contained in the feedstocks. Free fatty acids cannot be converted into biodiesel using homogeneous base-mediated processes. The CCAT catalyst system offers an integrated and cooperative catalytic

  3. Applications of optical sensors for high-frequency water-quality monitoring and research (United States)

    Pellerin, Brian


    meet high-quality standards requires investment in and adherence to tested and established methods and protocols for sensor operation and data management (Pellerin et al., 2013). For example, optical sensor measurements can be strongly influenced by a variety of matrix effects, including water temperature, inner filtering from highly colored water, and scattering of light by suspended particles (Downing et al., 2012). Characterizing and correcting sensors for these effects – as well as the continued development of common methodologies and protocols for sensor use – will be critical to ensuring comparable measurements across sites and over time. In addition, collaborative efforts such as the Nutrient Sensor Challenge ( will continue to accelerate the development, production and use of affordable, reliable and accurate sensors for a range of environments.

    Full Text Available A wide conception of state administration would also include the science of economics. With the triumphal progress of the doctrine of Adam Smith from the end of the 18th century this part of state administration also came within the sphere of influence of the national economy. This formed a theoretical partial discipline, which subsumed the determinants of the development of wealth. This theoretical part, the pure theory of political economy, contained those principles which should determine the practical part, the practice of economics. On the other hand, the theory of political economy considered practice in the process of the drafting of economic postulates. Both partial disciplines interacted and influenced the doctrines of state administration. This process will be described by means of writers influenced by the work of Adam Smith (Sartorius, Kraus, Lüder, Soden, Jakob, Lotz, Rau and using the example of governmental financial support for private enterprises. All these authors shared the doctrine of the absence of state intervention. But the state was nevertheless considered responsible for the prosperity of the country and had to intervene if private means failed and if the public welfare was to be protected. Based on these assumptions, criteria for the justification of state assistance were developed. Financial support was acceptable as sponsorship for innovation, as temporary aid in times of crisis and as an instrument of socio-political stabilization. The same types of financial aid were practiced by government. In the administration of states based on the rule of law (Robert von Mohl, national-economic and judicial principles moved in the same direction. The justifications of financial aid were concordant with the economic justifications. Thus the shaping of the national economy took on a juridical character.

  6. Relativistic and noise effects on multiplayer Prisoners' dilemma with entangling initial states (United States)

    Goudarzi, H.; Rashidi, S. S.


    Three-players Prisoners' dilemma (Alice, Bob and Colin) is studied in the presence of a single collective environment effect as a noise. The environmental effect is coupled with final states by a particular form of Kraus operators K_0 and K_1 through amplitude damping channel. We introduce the decoherence parameter 0≤p≤1 to the corresponding noise matrices, in order to controling the rate of environment influence on payoff of each players. Also, we consider the Unruh effect on the payoff of player, who is located at a noninertial frame. We suppose that two players (Bob and Colin) are in Rindler region I from Minkowski space-time, and move with same uniform acceleration (r_b=r_c) and frequency mode. The game is begun with the classical strategies cooperation ( C) and defection ( D) accessible to each player. Furthermore, the players are allowed to access the quantum strategic space ( Q and M). The quantum entanglement is coupled with initial classical states by the parameter γ \\in [0,π /2]. Using entangled initial states by exerting an unitary operator \\hat{J} as entangling gate, the quantum game (competition between Prisoners, as a three-qubit system) is started by choosing the strategies from classical or quantum strategic space. Arbitrarily chosen strategy by each player can lead to achieving profiles, which can be considered as Nash equilibrium or Pareto optimal. It is shown that in the presence of noise effect, choosing quantum strategy Q results in a winning payoff against the classical strategy D and, for example, the strategy profile ( Q, D, C) is Pareto optimal. We find that the unfair miracle move of Eisert from quantum strategic space is an effective strategy for accelerated players in decoherence mode (p=1) of the game.

    We present the results of a search for new members of the Taurus star-forming region using data from the Spitzer Space Telescope and the XMM-Newton Observatory. We have obtained optical and near-infrared spectra of 44 sources that exhibit red Spitzer colors that are indicative of stars with circumstellar disks and 51 candidate young stars that were identified by Scelsi and coworkers using XMM-Newton. We also performed spectroscopy on four possible companions to members of Taurus that were reported by Kraus and Hillenbrand. Through these spectra, we have demonstrated the youth and membership of 41 sources, 10 of which were independently confirmed as young stars by Scelsi and coworkers. Five of the new Taurus members are likely to be brown dwarfs based on their late spectral types (>M6). One of the brown dwarfs has a spectral type of L0, making it the first known L-type member of Taurus and the least massive known member of the region (M ∼ 4-7 M Jup ). Another brown dwarf exhibits a flat infrared spectral energy distribution, which indicates that it could be in the protostellar class I stage (star+disk+envelope). Upon inspection of archival images from various observatories, we find that one of the new young stars has a large edge-on disk (r = 2.''5 = 350 AU). The scattered light from this disk has undergone significant variability on a timescale of days in optical images from the Canada-France-Hawaii Telescope. Using the updated census of Taurus, we have measured the initial mass function for the fields observed by XMM-Newton. The resulting mass function is similar to previous ones that we have reported for Taurus, showing a surplus of stars at spectral types of K7-M1 (0.6-0.8 M sun ) relative to other nearby star-forming regions, such as IC 348, Chamaeleon I, and the Orion Nebula Cluster.

    Highlights: • L XRF production cross-sections for {sup 62}Sm at excitation energies 6.8, 7.4 and 8 KeV were measured. • Synchrotron radiations with Peltier cooled Si(Li) detector was employed. • Experimental L XRF cross sections are in good agreement with the theoretical estimations of Puri’s data. • The present study was also carried out to examine the effect of Coster - Kronig transitions on L XRF cross section. • The measured enhancement factors are found to be smaller than the theoretical estimations. - Abstract: L{sub ℓ}, L{sub α} and L{sub β} XRF production cross-sections were measured for {sup 62}Sm at excitation energies i.e. 6.8 KeV, 7.4 KeV and 8 KeV using synchrotron radiations. Experimental measurements were also carried out to examine the effect of Coster–Kronig transitions (non-radiative transitions) on fluorescence cross section for the L{sub i} (i = 1, 2, 3) X-ray lines. The experimental cross-sections with greater accuracy and better signal to noise ratio can be measured using a polarized monoenergetic excitation beam and a high resolution detector system. A Peltier cooled vortex solid state detector with energy resolution of 138 eV at 5.959 keV X-ray was employed. Experimentally measured cross-sections have been compared with the theoretical predictions with the data of M.O. Krause [J. Phys. Chem. Ref. Data 8 (1979) 307], J.L. Campbell [At. Data Nucl. Data Tables 85 (2003) 291] and S. Puri et al. [X-Ray Spectrom. 22 (1993) 358]. The measured enhancement factors were found to be smaller than the theoretically calculated values.

  11. Historical perspective on neurosurgery in Germany after World War II. (United States)

    Collmann, Hartmut; Vitzthum, Hans-Ekkehart


    AFTER THE COLLAPSE of the Third Reich, the specialty of neurosurgery in Germany, although well developed in the late 1930s, had to start anew, and for decades to come, had to deal with the physical and political consequences of World War II. Because of the division of the country, neurosurgery developed separately in the two independent states. In West Germany, the evolution was promoted by a few personalities who represented different schools according to their own training: these "surgical neurologists" emphasized the neurological basis of neurosurgery and were represented by Traugott Riechert and the students of Otfrid Foerster, such as Arist Stender and Hans Kuhlendahl. In contrast, the "neurological surgeons" stressed their origins in general surgery. Their main proponent was Wilhelm Tönnis, who gained particular merit for promoting neurosurgical teaching, the development of new neurosurgical units, and the recognition of neurosurgery as an autonomous specialty. In East Germany, progress was delayed by a weak economy and a repressive political system. Yet several excellent neurosurgeons won international recognition, predominantly Georg Merrem, who came from the school of Fedor Krause. Following a worldwide trend, the number of neurosurgical units in West Germany increased dramatically from 18 in 1950 to 85 in 1988. In 2006, in the unified nation, 1200 certified neurosurgeons in 138 hospital departments and 75 private practices served 82 million people. Since its founding in 1949, the German Neurosurgical Society has promoted the idea of reconciliation and has focused on international collaboration in both science and education. This idea, shared by other European nations, eventually gave rise to the European Association of Neurosurgical Societies. At present, escalating costs in the health sector pose a problem to neurosurgical services and have led to reconsiderations about their structure and financing.

  12. The potential of using KMOS for multi-object massive star spectroscopy (United States)

    Wegner, Michael; Bender, Ralf; Sharples, Ray; KMOS Team


    KMOS, the ``K-Band Multi-Object Spectrometer'', was built by a British-German consortium as a second generation instrument for the ESO Paranal Observatory. It is available to the user community since its successful commissioning in 2013 (Sharples et al. 2013). As a multi-object integral field spectrometer for the near infrared, KMOS offers 24 deployable IFUs of 2.8x2.8 arcsec and 14x14 spatial pixels each, which can either be placed individually within a 7.2 arcmin field of view or combined in a Mosaic mode in order to map contiguous fields on sky. The instrument covers the whole range of NIR atmospheric windows (0.8. . .2.5μm) with 5 spectral bands and a resolution of R ~ 3000. . .4000. Although the main science driver for KMOS was to enable the study of galaxy formation and evolution through multiplexed observations of high-redshift galaxies, KMOS also already exhibited its tremendous potential for the spectroscopy of massive stars: A quantitative study of 27 RSGs in NGC 300 (Gazak et al. 2015) proves its applicability for the spectroscopy of individual stars even beyond the Local Group. A Mosaic observation of the Galactic centre (Feldmeier-Krause et al. 2015) demonstrates how spectra of early-type stars can be extracted from a contiguous field. Other applications include (but need not be limited to) velocity determinations of globular cluster stars, observations of jets/outflows of high mass protostars, or contiguous mapping of star-forming regions. We therefore aim at presenting the excellent capabilities of KMOS to a wider community and indicate potential applications.

  13. Perspectives for research of the procrastination phenomenon in professional work

    Directory of Open Access Journals (Sweden)

    Valentina V. Barabanshchikova


    Full Text Available The paper describes the current state of the procrastination phenomenon in professional work, reviews the basic unexplored aspects in this area, and highlights the promising areas of scientific analysis. The survey of the existing literature periodization shows that the quantity of researches devoted to procrastination is growing exponentially every year. In spite of a pronounced research interest in this construct, in native and foreign psychological science procrastination phenomenon in the professional work is represented insufficiently. Firstly, there is no common and generally accepted definition of procrastination (Corkin, Yu, Lindt, 2011; Steel, 2010; Krause, Freund, 2014, that suggests that there is a deep terminological crisis in this area. Secondly, the characteristic of delaying the implementation of the elements of workload is represented only by the example of a fairly narrow range of professional activities, which makes it relevant to study the specificity of the differentiated functioning of the phenomenon on the material of a wide range of professions. Thirdly, in psychology there are no information about the peculiarities of the so-called “active” procrastination manifestations in professional activity, which is the tendency of conscious assignments delaying to achieve the optimum final result (Chu, Choi, 2005; Choi, Moran, 2009. Fourthly, there is an acute shortage of standardized psychodiagnostic tools to evaluate this phenomenon in work (most of the existing methods have been tested on samples of students and are aimed at identifying academic procrastination. In the fifth place, there are no science-based allocation of methods of coping with destructive manifestations of the psychological strategy of the job functions postponement in a professional work.

  14. The influence of corrective exercises in a water environment on the shape of the antero-posterior curves of the spine and on the functional status of the locomotor system in children with Io scoliosis. (United States)

    There has been a growing interest in studies examining the importance of the aquatic environment in non-invasive treatment of scoliosis. The water environment is an important element in the correction of body posture abnormalities. The aim of this paper is to evaluate the influence of corrective exercises in a water environment on the shape of the antero-posterior curves of the spine and on the functional status of the locomotor system of children with Io scoliosis. The study involved a group of 94 children aged 8-13 years with Cobb Io scoliosis. Computer-aided photogrammetry was used to analyse the shape of the antero-posterior curves of the spine. The functional evaluation of the children's musculoskeletal system involved several functional tests: the Dega wall test, Thomas test, Lasegue test, and Kraus-Weber test. The tests were carried out twice: before a 6-month programme of corrective exercises in a water environment, and immediately on completion of the rehabilitation programme. The programme included swimming and corrective exercises in water. A statistical analysis of the dimensions of the anterio-posterior curves of the spine revealed a significant increase in the total length of the spine and the length of thoracic kyphosis. Besides, the bending angle of the trunk, the angle of thoracic kyphosis and the angle of lumbar lordosis were reduced. The analysis also showed an increase in the bending angle of the upper spine. Shoulder mobility also increased significantly following the programme of corrective aquatic exercises. 1. The programme of corrective exercises had an influence on the length and angle of thoracic kyphosis. 2. The muscle strength of the lower part of the erector spinae also increased, as did shoulder mobility measured by the Dega test.

  15. The Grotesque Masks of Elias Canetti: Monads with no Doors or Windows

    Directory of Open Access Journals (Sweden)

    Jelena Ulrike Reinhardt


    Full Text Available For Elias Canetti comedy was always an important tool to express himself. But in his works, besides the link to comic, laughter has also a terrible, uncanny and creepy appearance. This disquieting side of laughter often leads to unheard of violence on the edge of madness. Canetti goes back to the archaic essence of laughter and shows the deep similarities with the act of eating. He considers the gesture of gulping down food as an act of incorporation, that is the first form of power and oppression. This type of humor finds an expression in different stylistic features of the grotesque. Through the analysis of some of his works, especially of his theatre plays and his novel Auto da fé, it clearly appears that the grotesque of Canetti is closely linked to the idea of mask. In this regard, Canetti’s definition of "acoustic mask" is by now well known. However, of great interest is the study of his literary  production in the light of a more complex meaning of the term mask, as the author himself points out in his anthropological essay Crowds and power, where alongside the acoustic elements he also includes visual ones. In this way, the broader concept of "grotesque mask" can be defined. This approach gives evidence of Canetti’s debt, not only towards acoustic elements related to his stay in  Vienna and to the influence of his great idol Karl Kraus, but also to the visual arts and, especially, to Brueghel and Goya. In sum, the grotesque masks show their inability to communicate not only in a verbal sense, but especially through their body language, as they are totally unable to touch each other in any way.

  18. Timing of the deposition of uppermost Cretaceous and Paleocene coal-bearing deposits in the Greater Glendive area, Montana and North Dakota

    Energy Technology Data Exchange (ETDEWEB)



    With the aid of a grant from the National Geographic Society, a cooperative agreement with the State University of New York at Stony Brook, and contract with the U.S. Department of Energy, Late Cretaceous and Paleocene geologic and paleontologic field studies were undertaken in Makoshika, State Park and vicinity, Dawson County, Montana. This region was chosen as a study area because of its potential for yielding new fossil localities and extensive exposures both above and below the K/T boundary, as suggested by previous research by David W. Krause and Joseph H. Hartman. Related field studies were also undertaken in areas adjacent to the Cedar Creek Anticline in North Dakota. This work was part of ongoing research to document change in the composition of mammalian and molluscan faunas during the Late Cretaceous and Paleocene and to relate observed patterns to floral and invertebrate changes in composition. This study focuses on the record of mammals and mollusks in the Makoshika stratigraphic section and places old and new observations into a paleomagnetic and palynomorph framework. Of particular interest is the appearance and diversification of archaic ungulate mammals. Simultaneous dinosaur extinction with ungulate radiation has been invoked in gradual, as opposed to catastrophic, models of faunal change at the K/T boundary. However, supposed Cretaceous localities bearing archaic ungulates and other mammals of {open_quotes}Paleocene aspect{close_quotes} may be the product of faunal reworking. Elsewhere in the Williston Basin (e.g., Garfield and McCone Counties, Montana), the molluscan record of uppermost Cretaceous and Paleocene strata indicates the extinction of all of the highly sculptured unionid bivalves just prior to the onset of coal swamps and subsequent coal formation.

  19. Can motto-goals outperform learning and performance goals? Influence of goal setting on performance and affect in a complex problem solving task

    Directory of Open Access Journals (Sweden)

    Miriam S. Rohe


    Full Text Available In this paper, we bring together research on complex problem solving with that on motivational psychology about goal setting. Complex problems require motivational effort because of their inherent difficulties. Goal Setting Theory has shown with simple tasks that high, specific performance goals lead to better performance outcome than do-your-best goals. However, in complex tasks, learning goals have proven more effective than performance goals. Based on the Zurich Resource Model (Storch & Krause, 2014, so-called motto-goals (e.g., "I breathe happiness" should activate a person’s resources through positive affect. It was found that motto-goals are effective with unpleasant duties. Therefore, we tested the hypothesis that motto-goals outperform learning and performance goals in the case of complex problems. A total of N = 123 subjects participated in the experiment. In dependence of their goal condition, subjects developed a personal motto, learning, or performance goal. This goal was adapted for the computer-simulated complex scenario Tailorshop, where subjects worked as managers in a small fictional company. Other than expected, there was no main effect of goal condition for the management performance. As hypothesized, motto goals led to higher positive and lower negative affect than the other two goal types. Even though positive affect decreased and negative affect increased in all three groups during Tailorshop completion, participants with motto goals reported the lowest rates of negative affect over time. Exploratory analyses investigated the role of affect in complex problem solving via mediational analyses and the influence of goal type on perceived goal attainment.

  20. The Impact of Mathematics Anxiety on Primary School Children’s Working Memory

    Directory of Open Access Journals (Sweden)

    Marcus Witt


    Full Text Available While there is little doubt that there is a connection between mathematics anxiety and poor mathematical performance, the direction and nature of this connection is less clear. Some researchers (e.g., Ma & Xu, 2004 have contended that poor mathematical performance directly causes mathematics anxiety. Others see a more complex relationship in which mathematics anxiety may, in part at least, cause poor mathematical performance. One possible explanation for the latter view is that mathematics anxiety leads directly to a disruption of cognitive processes such as working memory, which leads directly to poorer mathematical performance (Hopko, Ashcraft, Gute, Ruggiero, & Lewis, 1998. The working memory component most consistently associated with mathematics anxiety is the central executive (Ashcraft & Krause, 2007, although there is evidence (Miller & Bichsel, 2004 that visual-spatial working memory is impaired by mathematics anxiety. This study sought to explore the suggestion (Ashcraft & Kirk, 2001 that the mere presence of digits might trigger an anxious reaction among children reporting high levels of mathematics anxiety, leading to a decrement in working memory performance. Children of 9 and 10 years of age reported levels of mathematics anxiety and undertook two working memory tasks, one measuring central executive functioning and the other measuring visual-spatial working memory. Each working memory task was completed twice, once using letters as the to-be-remembered stimuli and again using digits. The differences in performance between the two versions of the tasks were compared with the reported levels of mathematics anxiety. The findings suggest that the presence of digits as the stimuli caused a decrement in working memory performance commensurate with the reported levels of mathematical anxiety.

    Neem plants (Rutales: Meliaceae) are well known for their multitude of human benefits in various fields. Specifically well investigated are the Indian neem tree Azadirachta indica A. Juss., the Thai neem A. siamensis Val., the originally Malaysian/Philippinean neem A. excelsa (Jack) and, as a close relative, the Persian lilac, Melia azedarach. The major and most active natural products are azadirachtin, salannin, nimbin and marrangin from Azadirachta species, and azadirachtin analogues like meliantriol from Melia species. Neem fruits, leaves, bark, and roots have specific virtues. They have been traditionally exploited for a considerable part of human history and are documented in Sanskrit texts. Due to human activity in trade and travel both at land and sea, the plant species has been distributed around the globe and is cultivated in many tropical, and subtropical regions. A multitude of natural products of neem have been isolated, chemically characterized or identified, and investigated for their properties in the management of insects, Acarina, Crustacea, nematodes, bacteria, fungi, viruses and soil fertility (for reviews see Kraus, 2002; Schmutterer, 2002A; Rembold, 2002; Koul, 2004; Schmutterer and Huber, 2005; Kleeberg and Strang, 2009; Hummel et al., 2008, 2011, 2012). Neem products are virtually nontoxic, compatible with beneficial insects, pollinators and bees. They are environmentally benign, sustainable, renewable, and of a price affordable for developed countries. In conclusion, neem is a prime example of a natural resource with many beneficial applications in agriculture, human and veterinary medicine. So far, its use is practically free of resistance problems which are frustratingly prevalent in many areas of synthetic insecticide and drug development. Investigating more neem applications will increase future human welfare and health while being of general ecological benefit to the planet.

  2. Searching for evidence of hydrothermal activity at Apollinaris Mons, Mars (United States)

    El Maarry, M. Ramy; Dohm, James M.; Marzo, Giuseppe A.; Fergason, Robin; Goetz, Walter; Heggy, Essam; Pack, Andreas; Markiewicz, Wojciech J.


    A multidisciplinary approach involving various remote sensing instruments is used to investigate Apollinaris Mons, a prominent volcano on Mars, as well as the surrounding plains for signs of prolonged hydrologic and volcanic, and possibly hydrothermal activity. The main findings include (1) evidence from laser altimetry indicating the large thickness (1.5–2 km at some locations) of the fan deposits draping the southern flank contrary to previous estimates, coupled with possible layering which point to a significant emplacement phase at Apollinaris Mons, (2) corroboration of Robinson et al. (Robinson, M.S., Mouginis-Mark, P.J., Zimbelman, J.R., Wu, S.S.C., Ablin, K.K., Howington-Kraus, A.E. [1993]. Icarus 104, 301–323) hypothesis regarding the formation of incised valleys on the western flanks by density current erosion which would indicate magma–water interaction or, alternatively, volatile-rich magmas early in the volcano’s history, (3) mounds of diverse geometric shapes, many of which display summit depressions and occur among faults and fractures, possibly marking venting, (4) strong indicators on the flanks of the volcano for lahar events, and possibly, a caldera lake, (5) ubiquitous presence of impact craters displaying fluidized ejecta in both shield-forming (flank and caldera) materials and materials that surround the volcano that are indicative of water-rich target materials at the time of impact, (6) long-term complex association in time among shield-forming materials and Medusae Fossae Formation. The findings point to a site of extensive volcanic and hydrologic activity with possibly a period of magma–water interaction and hydrothermal activity. Finally, we propose that the mound structures around Apollinaris should be prime targets for further in situ exploration and search for possible exobiological signatures.

    Hay Kraus BL


    Full Text Available Bonnie L Hay Kraus Department of Veterinary Clinical Sciences, Iowa State University College of Veterinary Medicine, Ames, IA, USA Abstract: Neurokinin-1 (NK-1 receptors are present in both the central nervous system and peripheral tissues. Substance P (SP is the major ligand and is involved in multiple processes including pain transmission, vasodilation, modulation of the inflammatory response, as well as the sensory neuronal transmission involved in stress, anxiety, and emesis. The involvement of NK-1 and SP in the vomiting reflex has led to the development of NK-1 antagonists to prevent and treat vomiting in human and veterinary medicine. Maropitant is a potent, selective neurokinin (NK-1 receptor antagonist that blocks the pharmacologic action of SP in the central nervous system. Maropitant is available in both an injectable and tablet formulation and approved for use in dogs and cats for the treatment and prevention of vomiting from a variety of clinical causes and motion sickness. When administered prior to anesthetic premedication, maropitant prevents or significantly decreases the incidence of opioid-induced vomiting and signs of nausea in dogs and cats. Maropitant has also been shown to improve postoperative return to feeding and food intake in dogs. The minimum alveolar concentration of sevoflurage is decreased in both dogs and cats by maropitant, indicating a potential role as an adjunct analgesic, especially for visceral pain. This article will review the background information and literature, including clinical recommendations with respect to the perioperative use of maropitant in canine and feline veterinary patients.

  4. Coherent chemical kinetics as quantum walks. I. Reaction operators for radical pairs. (United States)

    Chia, A; Tan, K C; Pawela, Ł; Kurzyński, P; Paterek, T; Kaszlikowski, D


    Classical chemical kinetics uses rate-equation models to describe how a reaction proceeds in time. Such models are sufficient for describing state transitions in a reaction where coherences between different states do not arise, in other words, a reaction that contains only incoherent transitions. A prominent example of a reaction containing coherent transitions is the radical-pair model. The kinetics of such reactions is defined by the so-called reaction operator that determines the radical-pair state as a function of intermediate transition rates. We argue that the well-known concept of quantum walks from quantum information theory is a natural and apt framework for describing multisite chemical reactions. By composing Kraus maps that act only on two sites at a time, we show how the quantum-walk formalism can be applied to derive a reaction operator for the standard avian radical-pair reaction. Our reaction operator predicts the same recombination dephasing rate as the conventional Haberkorn model, which is consistent with recent experiments [K. Maeda et al., J. Chem. Phys. 139, 234309 (2013)], in contrast to previous work by Jones and Hore [J. A. Jones and P. J. Hore, Chem. Phys. Lett. 488, 90 (2010)]. The standard radical-pair reaction has conventionally been described by either a normalized density operator incorporating both the radical pair and reaction products or a trace-decreasing density operator that considers only the radical pair. We demonstrate a density operator that is both normalized and refers only to radical-pair states. Generalizations to include additional dephasing processes and an arbitrary number of sites are also discussed.

  5. Explorative socio-environmental survey for honey quality assessment in six target provinces of Burkina Faso.

    Tania Cencetti


    Full Text Available Honeybees and bee products are optimal monitors for environment quality. Twelve honey and wax samples from six hives located in six different provinces of Burkina Faso, sited near agricultural crops, were analyzed. Two honey flow periods were taken into account: the main honey flow, during the dry season, and the second one, occurring at the end of the rainy season. Physico-chemical parameters (water, total sugars, hydroxy-methyl-furfural content, conductivity, pH and acidity and residual pesticide analysis were carried out to verify honey quality. Melissopalynological analysis was conducted to establish the botanical origin of honey samples. Five samples were identified as monoflorals, with a predominance of Lannea microcarpa Engl. & K.Krause, Vitellaria paradoxa C. F. Gaertn., Cassia mimosoides L. and Combretum Loefl. genus. Pollen profiles obtained by palynological analysis were compared with plant biodiversity present in the sampling area, which covered seven square kilometers. Ninety beekeepers were interviewed about their perception of the impact of agricultural pesticide use on honeybee colonies. As a first result, pesticides were absent both in honey and in wax samples. On the other hand, data showed that honey quality needed to be increased and beekeeping techniques improved. In general, further researches are recommended, to enhance the knowledge on the characteristics of Burkina Faso’s honeys and verify the specific impact of pesticides on Apis mellifera adansonii Latreille life-cycle and bee-products. The improvement of honey quality could ensure a best-selling price, opening new sale channels for Burkinabé beekeepers and farmers; at the same time, it could guarantee ecosystem pollination service and biodiversity conservation.

  6. Interactive Learning Program (ILP)- a concept for life long learning and Capacity Building of Stakeholders in Integrated Flood Management (IFM) (United States)

    Pasche, E.; Manojlovic, N.; Basener, S.; Behzadnia, N.


    In the paradigm shift in flood management from traditional to more integrated approach the key to initialising this transition stage is capacity building of stakeholders. It supports the effective participation of stakeholders within their role by giving the individuals/professionals and institutions required knowledge and skills. Such a process of empowering targeted stakeholder groups should be based on the interactive learning rather than mere delivering of flood related information. It can be achieved by initiating the learning process and developing life-long learning programs in form of blended learning that combines both, supervised online and face-to-face approaches. The learning concept based on the didactic principle of Kolb/Fry, has been used as a basis for development of the Interactive Learning Program (ILP) presented in this paper. Kolb/Fry define learning as a cyclic process dividing it into four steps: concrete experience, reflection & observation, forming abstract concepts, testing of acquainted knowledge in new situations. As the knowledge to understand the complexity of IFM is extensive and required level usually cannot be achieved within the face-to-face phase, additional autodidactic learning module tailored to the individual skills should be included in the learning program. ILP combines both, the face-to-face sessions following the Kolb?s learning cycle including theoretical and practical aspects and autodidactic phase by means of the e-learning platform based on the web dissemination strategy for IFM- Kalypso Inform (Pasche/Kraus/Manojlovic). According to this strategy, the access to the flood related information is enabled through three different modules Tutorial, Knowledge Base and Virtual Trainer enabling interaction with the system. This ILP is generic and can be tailored to requirements of different stakeholder groups depending on their role and level of integration in IFM. The first results, obtained for both public and private

    Electronic patient portals provide a new method for sharing personal medical information with individual patients. Our aim was to review utilization patterns of the largest online patient portal in Canada's largest city. We conducted a 4-year time-trend analysis of aggregated anonymous utilization data of the MyChart patient portal at Sunnybrook Health Sciences Centre in Ontario, Canada, from January 1, 2012, through December 31, 2015. Prespecified analyses examined trends related to day (weekend vs weekday), season (July vs January), year (2012 vs 2015), and an extreme adverse weather event (ice storm of December 20-26, 2013). Primary endpoints included three measures of patient portal activity: registrations, logins, and pageviews. We identified 32,325 patients who registered for a MyChart account during the study interval. Time-trend analysis showed no sign of attenuating registrations over time. Logins were frequent, averaged 734 total per day, and showed an increasing trend over time. Pageviews mirrored logins, averaged about 3029 total per day, and equated to about 5 pageviews during the average login. The most popular pageviews were clinical notes, followed by laboratory results and medical imaging reports. All measures of patient activity were lower on weekends compared to weekdays (Pmalware attack, or software failure occurred during the study. Online patient portals can provide a popular and reliable system for distributing personal medical information to active patients and may merit consideration for hospitals. ©Donald A Redelmeier, Nicole C Kraus.

  8. Conceptual model for invasive bivalve control on wetland productivity (United States)

    Hartman, Rosemary; Brown, Larry R.; Thompson, Janet K.; Parchaso, Francis


    Tidal wetlands were the historically dominant features of many coastal regions around the world, including the San Francisco Estuary (Callaway et al. 2011; Whipple et al. 2012). These mosaics of varied interconnected habitats (Mitsch and Gosselink 1993) provide a host of ecosystem services, including biodiversity maintenance, fish and wildlife habitat, water quality improvement, flood abatement, and carbon sequestration (Rabenhorst 1995; Costanza et al. 1997; Bottom et al. 2005; Zedler and Kercher 2005; Barbier et al. 2010). They also support human activities and values such as recreation and aesthetic appreciation (Barbier et al. 2010; Milligan and Kraus-Polk 2016). Despite their critical functions, many wetland landscapes have been destroyed or irreparably altered, either incidentally or intentionally, by human activities (Holland et al. 2004; Zedler and Kercher 2005; Callaway et al. 2011; Cloern and Jassby 2012; Whipple et al. 2012; Schile et al. 2014). San Francisco Estuary (SFE) (see Figure 1) tidal wetlands were largely converted to other land uses in the late 1800s and early 1900s, with the extent of loss and new use varying by region. Wetland losses in the North, Central, and South San Francisco bays and Suisun Bay ranged from 70 percent to 93 percent to accommodate agricultural uses, salt production, managed waterfowl habitat, and urban development (Callaway et al. 2011). Landscape transformation within the most inland portion of the SFE, the Sacramento-San Joaquin Delta (Delta), was even more dramatic. Overall, today’s Delta contains 97 percent less freshwater tidal wetland than its historical state and nearly double the open water area (Whipple et al. 2012). The majority of the modern Delta consists of agricultural tracts protected from tidal waters by human-made dikes or levees, which are commonly armored with riprap. The de-watered, rich peat soils of these created islands have supported abundant agricultural production, but have oxidized, compacted

  10. New insights on multiplicity and clustering in Taurus. (United States)

    Joncour, Isabelle; Duchene, Gaspard; Moraux, Estelle; Mundy, Lee


    Multiplicity and clustering of young stars are critical clues to constraint star formation process. The Taurus molecular complex is the archetype of a quiescent star forming region that may retain primeval signature of star formation.Using statistical and clustering tools such as nearest neighbor statistics, correlation functions and the density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm, this work reveals new spatial substructures in Taurus.We have identified unexpected ultra wide pairs (UWPs) candidates of high order multiplicity in Taurus in the 5-60 kAU separation range (Joncour et al 2017), beyond the separation assessed for wide pairs (Kraus & Hillenbrand 2009).Our work reveals 20 local stellar substructures, the Nested Elementary Structures (NESTs). These NESTs contain nearly half the stars of Taurus and 75% of the Class 0/I objects probing that they are the preferred sites of star formation (Joncour et al, sub.). The NESTs size ranges from few kAU up to 80 kAU making a length scale bridge between wide pairs and loose group (few hundreds kAU, Kirk & Myers, 2011). The NESTs mass ranges from 0.5-10 solar mass. The balance between Class I, II and III in NESTs suggests that they may be ordered as an evolutionary temporal scheme, some of them got infertile, while other shelter stars in infancy.The UWPs and the NESTs may be pristine imprints of their spatial configuration at birth. The UWPs population may result from a cascade fragmentation scenario of the natal molecular core. They could be the older counterparts, to the 0.5 Myr prestellar cores/Class 0 multiple objects observed at radio/millimeter wavelengths (Tobin et al 2010, 2016) and the precursors of the large number of UWPs (10–100 kAU) recently identified in older moving groups (Floriano-Alonso et al, 2015 ; Elliot et al 2016). The NESTs may result from the gravitational collapse of a gas clump that fragments to give a tight collection of stars within few millions years

    Estudiamos en este artículo el enigma de la grandeza del sueño vienés, confrontando las obras de sus tres principales representantes: Klimt, Shiele y Kokoschka, que cerraron el s.XIX, y se adentraron con fuerza en el s.XX, mostrándonos su inquietante cambio, mediante los primeros destellos de una luz nueva, nacida en el corazón de la vieja Europa aún poderosa, pese al desgarro de la Primera Guerra Mundial. KLIMT fue el auténtico creador de la Gran Escuela Vienesa. El carácter extraordinario de su arte consistió en haber logrado una síntesis entre las dos tendencias fundamentales de su momento: el Simbolismo y el Art Nouveau. Su idea fué la «creación de una obra de arte total», grande, moderna y democrática, en la que el progreso de la cultura se basase en una compenetración entre los fines artísticos y los aspectos más diversos de la vida moderna. Su filosofía, basada en Shopenhauer, reunía las fuerzas de la voluntad con las del mal, afirmando que : «un sincero abrazo a todo el mundo no podía darlo la vida», sino solo el arte liberado de la voluntad. Su discípulo Shiele, quien sobrevivió al maestro unos meses, (ya que solo vivió durante 28 años, se diferenció enseguida del «deseo de triunfo de la vida», presente en la obra de su profesor, mediante los ejemplos fantasmagóricos que confirió a sus telas, impregnando a sus mejores cuadros de toda la desesperación que es posible transmitir a través de sus torturados personajes. Y finalmente Kokoschska, hizo que la sustancia misma de su obra, fuese la representación de un siglo, que al menos en dos ocasiones, había cambiado la faz de Europa, testimoniando con su mirada penetrante la degradación social y cultural del imperio. Secundado por el escritor y periodista Karl Kraus y el filósofo Wittgenstein, realizó imágenes de tal violencia plástica que se le ha considerado como un expresionista austriaco, más que como un aut

  15. Evaluation of the Dopamine Hypothesis of ADHD with PET Brain Imaging

    Energy Technology Data Exchange (ETDEWEB)

    Swanson, James (University of California, Irvine)


    The Dopamine (DA) Hypothesis of ADHD (Wender, 1971; Levy, 1990) suggests that abnormalities in the synaptic mechanisms of DA transmission may be disrupted, and specific abnormalities in DA receptors and DA transporters (DAT) have been proposed (see Swanson et al, 1998). Early studies with small samples (e.g., n = 6, Dougherty et al, 1999) used single photon emission tomography (SPECT) and the radioligand (123I Altropane) to test a theory that ADHD may be caused by an over expression of DAT and reported 'a 70% increase in age-corrected dopamine transporter density in patients with attention deficit hyperactivity disorder compared with healthy controls' and suggested that treatment with stimulant medication decreased DAT density in ADHD patients and corrected an underlying abnormality (Krause et al, 2000). The potential importance of these findings was noted by Swanson (1999): 'If true, this is a major finding and points the way for new investigations of the primary pharmacological treatment for ADHD (with the stimulant drugs - e.g., methylphenidate), for which the dopamine transporter is the primary site of action. The potential importance of this finding demands special scrutiny'. This has been provided over the past decade using Positron Emission Tomography (PET). Brain imaging studies were conducted at Brookhaven National Laboratory (BNL) in a relatively large sample of stimulant-naive adults assessed for DAT (11C cocaine) density and DA receptors (11C raclopride) availability. These studies (Volkow et al, 2007; Volkow et al, 2009) do not confirm the hypothesis of increased DAT density and suggest the opposite (i.e., decreased rather than increased DAT density), and follow-up after treatment (Wang et al, 2010) does not confirm the hypothesis that therapeutic doses of methylphenidate decrease DAT density and suggests the opposite (i.e., increased rather than decreased DAT density). The brain regions implicated by these PET imaging studies also

  16. Computer modeling of pesticide fate at the hillslope scale. Influence of vegetated filter strips on surface runoff pesticides transfer and partitioning between surface and subsurface fluxes (United States)

    Djabelkhir, K.; Carluer, N.; Lauvernet, C.


    In France, agriculture uses large quantities of fertilizer and pesticides. Water contamination by pesticides is highlighted by monitoring networks, at local and national levels. Control and reduction of contamination are major issues, for the protection of drinking water resources and aquatic ecosystems. Thus, understanding and quantifying the mechanisms involved in mobilization, transfer and dissipation of these substances can help to perform risk of water contamination diagnosis, and to estimate the effectiveness of corrective solutions. In this context, landscape elements, like buffer zones, can be an effective way to reduce diffuse contamination of pesticides carried by surface runoff. They protect the water ressources of the drift of the products applied to crops and contribute to the reduction of the transfer of pesticides in surface runoff from the plots to the river. We are interested in our study to the vegetative filter strips. The main objective of this thesis is to develop a model simulating the processes governing the transfer and dissipation of pesticides from plots to surface water, on surface and subsurface, along a slope. This will be done by taking into account the influence of vegetative filter strips between plots and rivers on the transfer, by changing the flow paths and retention time of these products via several mechanisms (infiltration, filtration of runoff -sedimentation of MES-, adsorption and degradation of products on the surface of the vegetative filter strips or infiltrated). Several models describing the mechanisms of transfer of water and solutes (sometimes) at a hillslope scale exist, in particular : POLA (Pinheiro and al., 1995), Openfluid (LISAH), J2000-JAMS (Krause and al., 2006), CatFlow (Zehe and al., 2000), tRIBS (Ivanov and al., 2004), Cathy 3D (Bixio and al., 2000) and CMF (Kraft and al., 2011). It was decided to choose a spatially distributed and object-oriented model, allowing to couple hydrological processes occuring

  17. Approaches to local climate action in Colorado (United States)

    Huang, Y. D.


    Though climate change is a global problem, the impacts are felt on the local scale; it follows that the solutions must come at the local level. Fortunately, many cities and municipalities are implementing climate mitigation (or climate action) policies and programs. However, they face many procedural and institutional barriers to their efforts, such of lack of expertise or data, limited human and financial resources, and lack of community engagement (Krause 2011). To address the first obstacle, thirteen in-depth case studies were done of successful model practices ("best practices") of climate action programs carried out by various cities, counties, and organizations in Colorado, and one outside Colorado, and developed into "how-to guides" for other municipalities to use. Research was conducted by reading documents (e.g. annual reports, community guides, city websites), email correspondence with program managers and city officials, and via phone interviews. The information gathered was then compiled into a series of reports containing a narrative description of the initiative; an overview of the plan elements (target audience and goals); implementation strategies and any indicators of success to date (e.g. GHG emissions reductions, cost savings); and the adoption or approval process, as well as community engagement efforts and marketing or messaging strategies. The types of programs covered were energy action plans, energy efficiency programs, renewable energy programs, and transportation and land use programs. Between the thirteen case studies, there was a range of approaches to implementing local climate action programs, examined along two dimensions: focus on climate change (whether it was direct/explicit or indirect/implicit) and extent of government authority. This benchmarking exercise affirmed the conventional wisdom propounded by Pitt (2010), that peer pressure (that is, the presence of neighboring jurisdictions with climate initiatives), the level of

  18. Correlative physiological and morphological studies of rapidly adapting mechanoreceptors in cat's glabrous skin. (United States)

    Iggo, A; Ogawa, H


    1. A total of fifty-four mechanoreceptor afferent units with fast conducting axons in the tibial nerve innervating the glabrous skin of the hind leg were isolated in anaesthetized cats. 2. Twenty-six rapidly adapting units (RA), eighteen slowly adapting units (SA) and ten Pacinian corpuscle units (PC) were differentiated from each other mainly on the presence of the off response in RA and PC units to a ramp stimulation, the persistence of discharges of the SA units during steady pressure on the receptive field and the classical tuning curve seen in the PC units. A few PC units in the hairy skin were also studied for comparison. 3. Lamellated corpuscles were found histologically in the skin of the receptive field of RA units and identified as Krause's corpuscle of cylindrical type by their superficial location in the cutaneous tissue and their structure revealed by electron microscopy. 4. Physiological characteristics of RA units to various forms of mechanical stimulation were studied and compared with those of the other two kinds of units. SA units had the lowest critical slope among three groups and PC units the highest. 5. The discharge pattern of RA and PC units to a ramp stimulation was found to be time-locked, whereas with SA unites only the first spike appeared at a fixed latency from the start of stimulation. 6. Some RA units showed a tuning curve which was flat from 10 to 200 Hz. Those with narrowly tuned curves had a best turning frequency at around 20 Hz. They were easily differentiated from the SA and PC units. SA units were tuned best at 5 HZ or less, and PC units at around 200 HZ. 7. The relation between the indentation velocity and amplitude of the ramp and the spike discharges was analysed in eleven RA units. In most cases the relation between identation velocity and maximum instataneous frequency was found to be best fit with a power function although other kinds of functions (linear, logarithmic, and logarithmic hyperbolic tangent) could also fit

  19. Coding of information about tactile stimuli by neurones of the cuneate nucleus. (United States)

    Douglas, P R; Ferrington, D G; Rowe, M


    1. The responses of cuneate neurones to controlled tactile stimulation of the foot pads were examined in unanaesthetized, decerebrate cats. The neurones were divided into three functional classes; one sensitive to steady tactile stimuli, and two dynamically sensitive classes which could be readily differentiated by their responsiveness to cutaneous vibration. Each class appeared to receive an exclusive input from only one of the three known groups of tactile receptors associated with the foot pads, namely the Pacinian corpuscles, the Merkel endings and the intradermal, encapsulated endings known as Krause or Meissner corpuscles. 2. Cuneate neurones responsive to steady indentation of the skin displayed approximately linear or sigmoidal stimulus-response relations over indentation ranges up to approximately 1.5--2 mm. Response variability at a fixed stimulus intensity was relatively low and showed little systematic change over the full range of the stimulus-response curves. 3. One class of dynamically sensitive cuneate neurones responded to cutaneous vibration over a range of approximately 5-80 Hz with maximal responsiveness around 30 Hz. The other class, the Pacinian neurones, responded over a range of approximately 80- greater than 600 Hz with maximal responsiveness at 200-400 Hz. The thresholds and combined band width of vibratory sensitivity of these populations were comparable with known subjective thresholds and range of cutaneous vibratory sensibility. 4. Responses of cuneate neurones were phase-locked to the vibratory stimulus suggesting that information about vibration frequency could be coded by the patterns of impulse activity. Quantitative measures indicated that maximal phase-locking occurred in responses to vibration frequencies of 10-50 Hz with a progressive decline at higher frequencies. Above 400 Hz, impulse activity occurred almost randomly throughout the vibratory stimulus cycle and therefore carried little further signal of vibratory frequency

  20. Testing for and the role of anal and rectal sensation. (United States)

    Rogers, J


    The rectum is insensitive to stimuli capable of causing pain and other sensations when applied to a somatic cutaneous surface. It is, however, sensitive to distension by an experimental balloon introduced through the anus, though it is not known whether it is the stretching or reflex contraction of the gut wall, or the distortion of the mesentery and adjacent structures which induces the sensation. No specific sensory receptors are seen on careful histological examination of the rectum in humans. However, myelinated and non-myelinated nerve fibres are seen adjacent to the rectal mucosa, but no intraepithelial fibres arise from these. The sensation of rectal distension travels with the parasympathetic system to S2, S3 and S4. The two main methods for quantifying rectal sensation are rectal balloon distension and mucosal electrosensitivity. The balloon is progressively distended until particular sensations are perceived by the patient. The volumes at which these sensations are perceived are recorded. Three sensory thresholds are usually defined: constant sensation of fullness, urge to defecate, and maximum tolerated volume. The modalities of anal sensation can be precisely defined. Touch, pain and temperature sensation exist in normal subjects. There is profuse innervation of the anal canal with a variety of specialized sensory nerve endings: Meissner's corpuscles which record touch sensation, Krause end-bulbs which respond to thermal stimuli, Golgi-Mazzoni bodies and pacinian corpuscles which respond to changes in tension and pressure, and genital corpuscles which respond to friction. In addition, there are large diameter free nerve endings within the epithelium. The nerve pathway for anal canal sensation is via the inferior haemorrhoidal branches of the pudendal nerve to the sacral roots of S2, S3 and S4. Anal sensation may be quantitatively measured in response to electrical stimulation. The technique involves the use of a specialized constant current generator

  1. Early-term effect of adult chondrocyte transplantation in an osteoarthritis animal model. (United States)

    Desando, Giovanna; Cavallo, Carola; Tschon, Matilde; Giavaresi, Gianluca; Martini, Lucia; Fini, Milena; Giardino, Roberto; Facchini, Andrea; Grigolo, Brunella


    In this study, we investigated the efficacy of the transplantation of autologous articular chondrocytes seeded onto a hyaluronan-based scaffold, known as Hyaff(®)-11, on the treatment of early cartilage lesions in a rabbit osteoarthritis (OA) model. The hypothesis of the study was that this treatment could enhance cartilage repair after OA induction. OA was surgically induced by Anterior Cruciate Ligament Transection (ACLT) in thirty rabbits. Animals were divided into three groups, according to treatment: group 1: ACLT; group 2: Chondrocytes+Hyaff-11; and group 3: Hyaff-11 alone. The animals were euthanized, respectively, at 3 and 6 months after the treatment. Histomorphometrical analyses were performed by means of fibrillation index, cartilage thickness, and subchondral bone thickness evaluations. Histological appearance was scored according to Modified Kraus' Mankin and Osteoarthritis Research Society International (OARSI) scores. Immunohistochemical analyses were carried out for type I and II collagens, MMP-1, and MMP-3. A comparison between groups and follow-up for each outcome was performed with the general linear model with Sidak correction. Histomorphometrical evaluations at 3 and 6 months demonstrated that OA lesions became significantly worse followed by Hyaff-11 treatment, whereas Chondrocytes+Hyaff-11 treatment had the best overall subjective grade. Overall raw histological scores demonstrated a significant improvement with chondro-hyaluronic acid (HA) treatment at 3 months compared with HA in cartilage repair processes. Immunohistochemical analyses displayed a strong positivity for type II collagen in the Chondrocytes+Hyaff-11group at 3 months compared with the HA group. No staining was observed in MMP-3 expression in this group at any experimental point. The use of Chondrocytes+Hyaff-11 for the treatment of early OA lesions produced, already at 3 months, a repair tissue showing better macroscopic, histological, and immunohistochemical results than

  2. Triple-ion anions and polynuclear complexing in supercritical electrolyte solutions (United States)

    Oelkers, Eric H.; Helgeson, Harold C.


    Calculation of accurate mineral solubilities in hydrothermal solutions requires dissociation constants for the predominant aqueous complexes in solution, many of which may be present in appreciable concentrations only at high temperatures. Consideration of dissociation constants representing the standard molal Gibbs free energy changes resulting from the electrostatic interaction of aqueous species indicates that triple ions such as NaCl 2- and Na 2Cl + may be major species in alkali metal halide solutions at high temperatures and low pressures where the dielectric constant of H 2O is ≲ 15. Molal triple ion dissociation constants were computed for temperatures from 400° to 800°C at pressures from 500 to 4000 bars using equations given by FUOSS and KRAUS (1933b), together with values of the effective electrostatic radii of aqueous ions generated from algorithms developed by TANGER and HELGESON (1988) and SHOCK et al. (1990). The logarithms of the calculated second stepwise dissociation constants (log K2) for 16 alkali metal and hydrogen halides typically decrease at 500 bars from ˜0 at 400° to ˜ -3 at 700°C, but they increase with increasing pressure from ˜ -3 at 500 bars to ˜0 at 3 kb and 700°C. Distribution of species calculations using these log K2 values and dissociation constants for 1:1 ion pairs ( OELKERS and HELGESON, 1988), together with activity coefficients generated by adopting the revised HKF ( HELGESON, KIRKHAM, and FLOWERS, 1981) equation of state ( TANGER and HELGESON, 1988) to calculate extended term parameters in the Hückel equation ( HELGESON et al., 1981) indicate that triple ions are the predominant species in low-pressure supercritical aqueous solutions at concentrations ≈ 0.8 m. Under these circumstances, polynuclear and mixed ligand complexes in natural electrolyte solutions such as KNaCl +, MgKCl 2+, ZnNaCl 2+, FeKCl 2+, Na 2ClSO 4-, etc. may have a substantial effect on the hydrothermal solubilities of minerals at high

  3. VizieR Online Data Catalog: Radio haloes in nearby galaxies (Heesen+, 2018) (United States)

    Heesen, V.; Krause, M.; Beck, R.; Adebahr, B.; Bomans, D. J.; Carretti, E.; Dumke, M.; Heald, G.; Irwin, J.; Koribalski, B. S.; Mulcahy, D. D.; Westmeier, T.; Dettmar, R.-J.


    We present radio continuum observations of 12 nearby (D=2-27Mpc) edge-on galaxies at two different frequencies, namely at 1.4 and 5GHz (one galaxy at 8.5GHz instead of 5GHz). Our sample includes 11 late-type spiral (Sb or Sc) galaxies and one Magellanic-type barred galaxy (SBm), which are all highly inclined (i>=76°). As part of our study we have obtained several additional radio continuum maps. We make these maps publicly available (as well as all the other radio continuum maps in the paper). For 4 galaxies (NGC 55, 253, 891 and 4631) we have used single-dish maps, to correct for the missing zero-spacing flux where necessary. The Effelsberg maps of NGC 253 and 4631 were already presented in Heesen et al. (2009A&A...494..563H) and Mora & Krause (2013A&A...560A..42M), respectively, and the Effelsberg map of NGC 891 was already presented in Dumke (1997, PhD thesis, University of Bonn). We present these maps for completeness. The 4.80-GHz map of NGC 55 obtained with the 64-m Parkes telescope is so far unpublished. Furthermore, we show two maps of NGC 4631 at 1.35 and 1.65GHz observed with the VLA in D- configuration (R. Beck 2016, priv. comm.). The data were observed in August 1996, with 12 h on-source (ID: AG486) and reduced in standard fashion with AIPS. The maps have an angular resolution of 52 arcsec, so that we did not use them in the analysis, but they also show the halo of this galaxy very well. Lastly, we obtained maps of three further edge-on galaxies observed with the VLA (NGC 4157, 4217 and 4634). We reduced the data as described in Section 2, but since we had only one frequency available and no spectral index map, we did not use them in the analysis. The maps of NGC 4157 and 4217 were created by re-reducing archive data (IDs AI23, AF85, AH457 and AS392 for NGC 4157 and ID AM573 for NGC 4217). The map of NGC 4634 was created by using so far unpublished data from the VLA (ID: AD538). (3 data files).

  4. A history of lumbar disc herniation from Hippocrates to the 1990s. (United States)

    Truumees, Eeric


    In ancient times, a supernatural understanding of the syndrome of lumbar radiculopathy often involved demonic forces vexing the individual with often crippling pain. The ancient Greeks and Egyptians began to take a more naturalistic view and, critically, suspected a relationship between lumbar spinal pathology and leg symptoms. Relatively little then changed for those with sciatica until the classic works by Cotugno and Kocher arrived in the late 18th century. Early lumbar canal explorations were performed in the late 1800s and early 1900s by MacEwen, Horsley, Krause, Taylor, Dandy, and Cushing, among others. In these cases, when compressive pathologies were found and removed, the lesions typically were (mis-)identified as enchondromas or osteochondritis dissecans. To better understand the history, learn more about the first treatments of lumbar disc herniation, and evaluate the impact of the early influences on modern spine practice, searches of PubMed and Embase were performed using the search terms discectomy, medical history, lumbar spine surgery, herniated disc, herniated nucleus pulposus, sciatica, and lumbar radiculopathy. Additional sources were identified from the reference lists of the reviewed papers. Many older and ancient sources including De Ischiade Nervosa are available in English translations and were used. When full texts were not available, English abstracts were used. The first true, intentional discectomy surgery was performed by Mixter and Barr in 1932. Early on, a transdural approach was favored. In 1938, Love described the intralaminar, extradural approach. His technique, although modified with improved lighting, magnification, and retractors, remains a staple approach to disc herniations today. Other modalities such as chymopapain have been investigated. Some remain a part of the therapeutic armamentarium, whereas others have disappeared. By the 1970s, CT scanning after myelography markedly improved the clinical evaluation of patients with

  5. The Mineral Collection of the University of Michigan: its History and Future (United States)

    Stefano, C. J.; Ewing, R. C.; Erwin, K.


    The mineral collection at the University of Michigan is among the oldest and finest in the Great Lakes region. The collection was created in 1838 with the purchase, under Douglass Houghton, one of the first professors at the University of Michigan, of 2,600 specimens, largely of European origin, from Baron Louis von Lederer of Vienna. This was one of the first major purchases by the Board of Regents. The collection was actively curated and continued to grow under the direction of Edward H. Kraus, one of the founders of the Mineralogical Society of America and the Chair of the then separate Department of Mineralogy. The collection is the repository for specimens collected by Douglass Houghton, as well as specimens collected during the first geological survey of Michigan. Specimens from Michigan's Keweenaw copper district are of exceptional quality, mainly due to the world-class specimens donated by then Regent L. L. Hubbard between 1917 and the mid-1920s. There is also a significant suite of fine Sicilian sulfur specimens collected during the Ph.D. research of Professor Walter F. Hunt. Other important suites include the Stuart H. Perry Meteorite collection, the Frederick S. Stearns gemstone collection, and a suite of Antarctic rock samples collected during the Byrd expedition in 1928-30. The collection also has a wide variety of worldwide specimens, mostly of reference quality, although there are several hundred excellent to world class pieces that do not fit into the core suites. Overall, the collection contains approximately 15,000 mineral specimens, about 1,000 meteorites, and several thousand gemstones and related materials. Although the collection continued to be an important part of the teaching and research efforts after the Departments of Mineralogy and Geology were merged in 1961, the collection was little used and without active curation through the latter half of the 20th Century. Recently, the University has initiated an inventory process prior to

  6. [Sciatica. From stretch rack to microdiscectomy]. (United States)

    Gruber, P; Böni, T


    In ancient times as well as in the Middle Ages treatment options for discogenic nerve compression syndrome were limited and usually not very specific because of low anatomical and pathophysiological knowledge. The stretch rack (scamnum Hippocratis) was particularly prominent but was widely used as a therapeutic device for very different spinal disorders. Since the beginning of the nineteenth century anatomical knowledge increased and the advances in the fields of asepsis, anesthesia and surgery resulted in an increase in surgical interventions on the spine. In 1908 the first successful lumbar discectomy was initiated and performed by the German neurologist Heinrich O. Oppenheim (1858-1919) and the surgeon Fedor Krause (1857-1937); however, neither recognized the true pathological condition of discogenic nerve compression syndrome. With the landmark report in the New England Journal of Medicine in 1934, the two American surgeons William Jason Mixter (1880-1958) and Joseph Seaton Barr (1901-1963) finally clarified the pathomechanism of lumbar disc herniation and furthermore, propagated discectomy as the standard therapy. Since then interventions on intervertebral discs rapidly increased and the treatment options for lumbar disc surgery quickly evolved. The surgical procedures changed over time and were continuously being refined. In the late 1960s the surgical microscope was introduced for spinal surgery by the work of the famous neurosurgeon Mahmut Gazi Yasargil and his colleague Wolfhard Caspar and so-called microdiscectomy was introduced. Besides open discectomy other interventional techniques were developed to overcome the side effects of surgical procedures. In 1964 the American orthopedic surgeon Lyman Smith (1912-1991) introduced chemonucleolysis, a minimally invasive technique consisting only of a cannula and the proteolytic enzyme chymopapain, which is injected into the disc compartment to dissolve the displaced disc material. In 1975 the Japanese orthopedic

  7. Tuning of spinal networks to frequency components of spike trains in individual afferents. (United States)

    Koerber, H R; Seymour, A W; Mendell, L M


    Cord dorsum potentials (CDPs) evoked by primary afferent fiber stimulation reflect the response of postsynaptic dorsal horn neurons. The properties of these CDPs have been shown to vary in accordance with the type of primary afferent fiber stimulated. The purpose of the present study was to determine the relationships between frequency modulation of the afferent input trains, the amplitude modulation of the evoked CDPs, and the type of primary afferent stimulated. The somata of individual primary afferent fibers were impaled in the L7 dorsal root ganglion of alpha-chloralose-anesthetized cats. Action potentials (APs) were evoked in single identified afferents via the intracellular microelectrode while simultaneously recording the response of dorsal horn neurons as CDPs, or activity of individual target interneurons recorded extracellularly or intracellularly. APs were evoked in afferents using temporal patterns identical to the responses of selected afferents to natural stimulation of their receptive fields. Two such physiologically realistic trains, one recorded from a hair follicle and the other from a slowly adapting type 1 receptor, were chosen as standard test trains. Modulation of CDP amplitude in response to this frequency-modulated afferent activity varied according to the type of peripheral mechanoreceptor innervated. Dorsal horn networks driven by A beta afferents innervating hair follicles, rapidly adapting pad (Krause end bulb), and field receptors seemed "tuned" to amplify the onset of activity in single afferents. Networks driven by afferents innervating down hair follicles and pacinian corpuscles required more high-frequency activity to elicit their peak response. Dorsal horn networks driven by afferents innervating slowly adapting receptors including high-threshold mechanoreceptors exhibited some sensitivity to the instantaneous frequency, but in general they reproduced the activity in the afferent fiber much more faithfully. Responses of

  8. Evaluation of the Dopamine Hypothesis of ADHD with PET Brain Imaging

    International Nuclear Information System (INIS)

    Swanson, James


    The Dopamine (DA) Hypothesis of ADHD (Wender, 1971; Levy, 1990) suggests that abnormalities in the synaptic mechanisms of DA transmission may be disrupted, and specific abnormalities in DA receptors and DA transporters (DAT) have been proposed (see Swanson et al, 1998). Early studies with small samples (e.g., n = 6, Dougherty et al, 1999) used single photon emission tomography (SPECT) and the radioligand (123I Altropane) to test a theory that ADHD may be caused by an over expression of DAT and reported 'a 70% increase in age-corrected dopamine transporter density in patients with attention deficit hyperactivity disorder compared with healthy controls' and suggested that treatment with stimulant medication decreased DAT density in ADHD patients and corrected an underlying abnormality (Krause et al, 2000). The potential importance of these findings was noted by Swanson (1999): 'If true, this is a major finding and points the way for new investigations of the primary pharmacological treatment for ADHD (with the stimulant drugs - e.g., methylphenidate), for which the dopamine transporter is the primary site of action. The potential importance of this finding demands special scrutiny'. This has been provided over the past decade using Positron Emission Tomography (PET). Brain imaging studies were conducted at Brookhaven National Laboratory (BNL) in a relatively large sample of stimulant-naive adults assessed for DAT (11C cocaine) density and DA receptors (11C raclopride) availability. These studies (Volkow et al, 2007; Volkow et al, 2009) do not confirm the hypothesis of increased DAT density and suggest the opposite (i.e., decreased rather than increased DAT density), and follow-up after treatment (Wang et al, 2010) does not confirm the hypothesis that therapeutic doses of methylphenidate decrease DAT density and suggests the opposite (i.e., increased rather than decreased DAT density). The brain regions implicated by these PET imaging studies also suggest that a

  10. Lutropin alpha, recombinant human luteinizing hormone, for the stimulation of follicular development in profoundly LH-deficient hypogonadotropic hypogonadal women: a review

    Directory of Open Access Journals (Sweden)

    Bernd Th Krause


    Full Text Available Bernd Th Krause1, Ralf Ohlinger2, Annette Haase31Center for Endocrinology and Reproductive Medicine, MVZ Uhlandstr, Berlin, Germany; 2Ernst-Moritz-Arndt-University, Department of Gynecology and Obstetrics, Greifswald, Germany; 3Uhlandstr. 162, 10719 BerlinAbstract: Hypogonadotropic hypogonadism is defined as a medical condition with low or undetectable gonadotropin secretion, associated with a complete arrest of follicular growth and very low estradiol. The main cause can be traced back to an irregular or absent hypothalamic GnRH secretion, whereas only a minority suffers from a pituitary disorder. The choice of treatment to reverse this situation is a pulsatile GnRH application or a direct ovarian stimulation using gonadotropin injections. The goal is to achieve a proper ovarian function in these cases for a short time to allow ovulation and chance of pregnancy. Since the pulsatile GnRH treatment lost its former importance, several gonadotropins are in use to stimulate follicular growth, such as urine-derived human menopausal gonadotropin, highly purified follicle stimulating hormone (FSH or recombinant FSH, all with different success. The introduction of recombinant luteinizing hormone (LH and FSH provided an opportunity to investigate the distinct influences of LH and FSH alone and in combination on follicular growth in monofollicular ovulation induction cycles, and additionally on oocyte maturation, fertilization competence of the oocyte and embryo quality in downregulated IVF patients. Whereas FSH was known to be indispensable for normal follicular growth, the role of LH remained questionable. Downregulated IVF patients with this short-term gonadotropin depletion displayed no advance in stimulation success with the use of recombinant LH. Patients with hypogonadotropic hypogonadism undergoing monofollicular stimulation for ovulation induction showed clearly a specific role and need for both hormones in normal follicular growth. Therefore, a

    Information on high-risk drug use in Turkey, particularly at the regional level, is lacking. The present analysis aims at estimating high-risk cannabis use (HRCU) and high-risk opiate use (HROU) in the cities of Ankara, Istanbul and Izmir. Capture-recapture and multiplier methods were applied based on treatment and police data stratified by age and gender in the years 2009 and 2010. Case definitions refer to ICD-10 cannabis (F.12) and opiate (F.11) disorder diagnoses from outpatient and inpatient treatment records and illegal possession of these drugs as recorded by the police. High-risk cannabis use was estimated at 28 500 (8.5 per 1000; 95% confidence interval 7.3-10.3) and 33 400 (11.9 per 1000; 95% confidence interval 10.7-13.5) in Ankara and Izmir, respectively. Using multipliers based on capture-recapture estimates for Izmir, HRCU in Istanbul was estimated up to 166 000 (18.0 per 1000; range: 2.8-18.0). Capture-recapture estimates of HROU resulted in 4800 (1.4 per 1000; 95% confidence interval 0.9-1.9) in Ankara and multipliers based on these gave estimates up to 20 000 (2.2 per 1000; range: 0.9-2.2) in Istanbul. HROU in Izmir was not estimated due to the low absolute numbers of opiate users. While HRCU prevalence in both Ankara and Izmir was considerably lower in comparison to an estimate for Berlin, the rate for Istanbul was only slightly lower. Compared with the majority of European cities, HROU in these three Turkish cities may be considered rather low.

  12. Investigation of the possible connection of rock and soil geochemistry to the occurrence of high rates of neurodegenerative diseases on Guam and a hypothesis for the cause of the diseases (United States)

    Miller, William R.; Sanzolone, Richard F.


    have neurotoxic effects (MacDonald and Martin, 1988), and aluminum has been implicated in the pathogenesis of Alzheimer’s disease and similar dementia by Perl and others (1982). Studies of soils developed on volcanic rocks on Guam and other islands by McLachlan and others (1989) found that soils on Guam averaged 42-fold higher yield of elutable aluminum than soils developed on volcanic rocks on Jamaica or Palau. They did not detect unusually high dietary aluminum or low dietary calcium, but concluded that the soils and possibly the dusts of Guam might be a major source of aluminum entering the body of the inhabitants. This study was conducted to investigate the geochemistry of the soils and rocks of the volcanic southern part of the island of Guam, particularly in the vicinity of the three southern villages (Umatac, Merizo, and Inarajan) with high incidences of the diseases. In addition to total chemical analyses of the soils and rocks, various extractions of soils were carried out. Both excesses and deficiencies of various elements were looked for. Because soluble aluminum in the soil was shown by McLachlan and others (1989) to be unusually high, water-soluble extractions as well as sequential extractions of the soils were carried out. In addition, elements such as aluminum found in dust can traverse the nose-brain barrier in experimental animals (Sunderman, 2000) and respiratory epithelium is known to contain the highest concentration of aluminum in the human body (Tipton and others, 1957). The availability of elements, particularly aluminum from human inhalation of dust, derived from soil, was investigated.

    Full Text Available We present new data on the paleoichthyology, paleobotany and radiometric results of the Loreto Formation in the Brunswick Peninsula of southernmost Chile, that allow us to propose a Late Eocene age. The rich diversity of fossil cartilaginous fishes (Chondrichthyes, Elasmobranchii recognized in upper levels of this unit includes the taxa Carcharías aff. 'hopef (Agassiz, Odontaspis sp., Carcharoides catticus (Philippi, Striatolamia macrota (Agassiz, Anomotodon sp., Macrorhizoduspraecursor (Leriche, Galeorhinus sp., Abdounia sp., Hexanchus sp., Squatina sp., Hexanchidae indet.,Myliobatis sp., Myliobatoidea indet., and Ischyodus dolloi Leriche. This assemblage has clear ecological affinities with Eocene Tethyan fauna previously described in the Northern Hemisphere, and also has common elements with Eocene cartilaginous fishes from Antarctica. Additionally, a paleobotanic study of this unit identified leaf imprints ofAsplenium sp., Pteris sp., Podocarpus sp., and abundant angiosperms including Nothofagus lanceolata Dusén, N. simplicidens Dusén, N. variabilis Dusén, N. cf. alessandri Espinosa, N. subferruginea (Dusén, Hydrangea sp. and Phyllites spp. Wood remains of Nothofagoxylon scalariforme Gothan and Araucariaceae cf. Araucarioxylon Kraus were also identified. Additionally, pollen grains indicate gymnosperms and angiosperms: Podocarpidites otagoensis Couper, Retitricolpites sp., Tricolpites sp., Liliacidites sp., Polyporina sp., Nothofagidites cincta Cookson, and Nothofagidites cranwellae Couper, having affinities with Eocene florae, and being consistent with the age of the fossil fishes. Finally, a SHRIMP U-Th-Pb analysis of two samples collected from the studied beds provided thirty-eight and sixty zircon grains, indicating a clear main peak at 36.48±0.47 Ma (MSWD=1.5 and 36,73±0.50 Ma (MSWD=0.65. The integrated results indicate that the upper part of the Loreto Formation has a minimum Priabonian age, supporting previous reassignations of

    Full Text Available Obezita v dětství i v dospělosti přináší spoustu zdravotních problémů. Obezita v dětství je také spojována s množstvím potenciálních zdravotních a psychosociálních komplikací stejně jako je rizikovým faktorem pro nárust morbidity a předčasného úmrtí v dospělosti. V posledních letech prevalence obezity mezi dětmi a adolescenty dramaticky stoupla především díky nezdravému životnímu stylu. Cílem studie je poskytnout základní informace o výskytu, prevenci a léčbě dětské obezity zaměřené především na fyzickou zdatnost, popsat komplexní lázeňskou léčbu ve Státních léčebných lázních Bludov zahrnující program pohybové aktivity, dietní opatření a psychologickou terapii a zjistit efekt měsíční lázeňské léčby na svalovou zdatnost a tělesnou výkonnost obézních dětí. Tato studie zahrnuje skupinu 26 obézních dětí, které podstoupily komplexní lázeňskou léčbu, a kontrolní skupinu neobézních dětí. Před a po lázeňské léčbě byla měřena svalová zdatnost a tělesná výkonnost obézních dětí pomocí Kraus-Weberova testu minimální svalové zdatnosti a testu obecné tělesné výkonnosti. Výsledky byly srovnány s hodnotami naměřenými u kontrolní skupiny neobézních dětí. Z výsledků studie vyplývá, že měsíčníní komplexní lázeňská léčba má velký vliv na svalovou zdatnost a tělesnou výkonnost obézních dětí. Childhood and adult obesity are associated with various health problems. Obesity in childhood is also coupled with a range of potential medical and psychosocial complications, as well as being a risk factor for increased morbidity and premature mortality in adulthood. In recent years, the prevalence of obesity among children and adolescents has risen dramatically due to unhealthy changes in lifestyle. The aim of this study was to provide some basic information about the incidence, prevention and treatment of obesity in

  17. Experimental evaluation of ALS point cloud ground extraction over different land cover in the Malopolska Province (United States)

    Korzeniowska, Karolina; Mandlburger, Gottfried; Klimczyk, Agata


    The paper presents an evaluation of different terrain point extraction algorithms for Airborne Laser Scanning (ALS) point clouds. The research area covers eight test sites in the Małopolska Province (Poland) with varying point density between 3-15points/m² and surface as well as land cover characteristics. In this paper the existing implementations of algorithms were considered. Approaches based on mathematical morphology, progressive densification, robust surface interpolation and segmentation were compared. From the group of morphological filters, the Progressive Morphological Filter (PMF) proposed by Zhang K. et al. (2003) in LIS software was evaluated. From the progressive densification filter methods developed by Axelsson P. (2000) the Martin Isenburg's implementation in LAStools software (LAStools, 2012) was chosen. The third group of methods are surface-based filters. In this study, we used the hierarchic robust interpolation approach by Kraus K., Pfeifer N. (1998) as implemented in SCOP++ (Trimble, 2012). The fourth group of methods works on segmentation. From this filtering concept the segmentation algorithm available in LIS was tested (Wichmann V., 2012). The main aim in executing the automatic classification for ground extraction was operating in default mode or with default parameters which were selected by the developers of the algorithms. It was assumed that the default settings were equivalent to the parameters on which the best results can be achieved. In case it was not possible to apply an algorithm in default mode, a combination of the available and most crucial parameters for ground extraction were selected. As a result of these analyses, several output LAS files with different ground classification were achieved. The results were described on the basis of qualitative and quantitative analyses, both being in a formal description. The classification differences were verified on point cloud data. Qualitative verification of ground extraction was

    exact diagonal- ization. In Part II, we deal with the compressed way of quantum computation mentioned above, used to simulate physically interesting behaviours of large systems. To give an example, consider an experimental set–up, where up to 8 qubits can be well controlled. Such a set–up can be used to simulate certain interactions of 2 8 = 256 qubits. In [Boyajian et al. (2013)], we generalised the results from [Kraus (2011)], and demonstrated how the adiabatic evolution of the 1D XY-model can be simulated via an exponentially smaller quantum system. More precisely, it is shown there, how the phase transition of such a model of a spin chain consisting out of n qubits can be observed via a compressed algorithm processing only log( n ) qubits. The feasibility of such a compressed quantum simulation is due to the fact that the adiabatic evolution and the measurement of the magnetization employed to observe the phase transition can be described by a matchgate circuit. Remarkably, the number of elementary gates, i.e. the number of single and two-qubit gates which are required to implement the compressed simulation can be even smaller than required to implement the original matchgate circuit. This compressed algorithm has already been experimentally realized using NMR quantum computing [Li et al. (2014)]. In [Boyajian et al. (2013)] we showed that not only the quantum phase transition can be observed in this way, but that various other interesting processes, such as quantum quenching, where the evolution is non–adiabatic, and general time evolutions can be simulated with an exponentially smaller system. In Part II, we also recall the results from [Boyajian and Kraus (2015)] where we extend the notion of compressed quantum simulation even further. We consider the XY-model and derive compressed circuits to simulate the behavior of the thermal and any excited state of the system. To this end, we use the diagonalization of the XY-Hamiltonian presented in[ Verstraete et al

    Full Text Available The issue of anticipation social support is actual topic because of detection important factors for positive development of personality. Emotional bonds are getting stronger with perception of social support. Subjective feeling of positive emotions and relationships is manifest with higher range of social and mental functioning, emotional - willing stability of personality. Emotional basement of personality is emotional stability, which represent relationship with the anticipated social support. The lack of social support make a negative influence on personality development and personality traits. Positive emotional relationsthips with parents are important for healthy growth of personality (Filadelfiová, 2001; Arrive, 2004; Vágnerová, 2000; Langmeier & Křejčířová, 2006; Grun, 2011; Kraus & Poláčková, 2001; Matulník, 2002; Matějček & Dytrych, 2002. The meaning of social support and partner's love is confirmed with research. The meaning of social support in adolescence is replaced from parents to life partner. Strong emotional relationship motivates, integrates and regulates (Vágnerová, 2000. Absence of positive and permanent emotional relationship hold the positive soul steadiness. The signs of soul unsteadiness are destruction of self-esteem and self-image which manifest unstable emotionality. Subjective survival of emotional and social disharmony influence mental problems - neurotic disorders, problems with adaptation, emotional and social problems (Kondáš, 2002. The goal of research was find out relationship of social support regarding with emotional-willing stability and adolescence relationships in their family. We were interested in level of social support and level of emotional- willing stability and perception of quality family relationships regarding with gender and actual partnership.

    This second joint conference between the APS Topical Group on Shock Compression of Condensed Matter and the International Association for the Advancement of High Pressure Science and Technology (AIRAPT) demonstrates that static and dynamic compression of condensed matter continues to be a vibrant field of science and engineering. It is also by its nature an interdisciplinary field, incorporating chemistry, materials science, solid mechanics, plasma physics, and condensed matter physics, and utilizes theoretical, computational, and experimental tools. Recent years have brought about many advances in loading platforms, diagnostics, and computations that are leading to the emergence of many new avenues of research. These advances are also breathing new life into traditional topics such as equations of state, phase transformations, and chemistry at extreme conditions. The plenary lectures by Gennady Kanel, Karl Syassen, David Ceperley, Jon Eggert, Duck Young Kim, and Richard Kraus spanned the disciplines of static and dynamic high pressure physics and illustrated the breadth of the field. They also showed that interesting and important problems remain for researchers of the future to solve. The main guiding principal in the organization of this conference was to intertwine static and dynamical experimental alongside computational and theoretical studies of similar materials. To achieve this goal, we arranged the conference to include static, dynamic, and computational components in the same sessions, quite often taking presenters out of their comfort zone. The three special sessions on Deep Carbon Budget (organized by Giulia Galli and Rus Hemley), High Energy Density Materials (organized by Raymond Jeanloz and Jon Eggert), and Dynamic Response of Materials (organized by Yogendra Gupta and John Sarrao) furthered this guiding principal. We also endeavored to represent the breadth of static and dynamic high pressure science and technology, notably beyond that done at

    should be based on a comprehensive sensitivity and uncertainty analysis (Bäse, 2005 and multi-response validations with independent data sets (Krause and Flügel, 2005 carried out in advance in the headwater part of the calibration basin. To obtain good results in the transfer basins the calibrated parameter set could be adjusted slightly. This step was considered as necessary because of specific constraints which were not of significant importance in the calibration basin. This readjustment should be carried out on parameters which show a sensitive reaction on the identified differences in the environmental setup. Potential scaling problems of the process description, distribution concept or model structure should be identified by the comparison of the modelling results obtained in a small headwater region of the calibration basin with observed streamflow to find out if the selected efficiency measures show a significant change.

  7. Česká literární moderna v časopise Aus fremden Zungen — čtyři příklady prostředkování // Czech literary modernism in the journal Aus fremden Zungen — four examples of mediation

    Directory of Open Access Journals (Sweden)

    Lucie Merhautová


    Full Text Available The study focuses on Bronislav Wellek, Adolph Donath, Camill Hoffmann, Oskar Wiener and Otto Hauser and their translations and articles on modern Czech literature published in the German journal Aus fremden Zungen (1891–1910. This fortnightly established by Joseph Kürschner dealt exclusively with foreign literature. Its openness to all kinds of literary currents and little-known minor literatures was unique within the system of German literary journals. A comparison indicates the key role played by mediators. The primary requirement for their activity was multilingualism, and it turns out that in the case of all the figures under consideration, language did not necessarily have the nationally symbolic significance ascribed by politics, and their identity basically did not depend on their use of one language or another. The progress and success of this mediation was not just decided by the literary standard of the translation, but all five translators were concerned to improve the standard of translation, as well as to change the approach to translation in general. The choice of text and its succeeded publication was determined by the involvement of the mediators in the Czech and German literary context. Hence Bronislav Wellek focused primarily on translations and interpretations of poetry by Jaroslav Vrchlický and J. S. Machar, whom he knew personally and who also introduced him to their own literary and intellectual circles. It was thanks to Vrchlický that he printed his translations in Eduard Albert’s anthologies Poesie aus Böhmen (1893–1895. Machar was responsible for other translations, e.g. Hilbert’s drama Vina, which Hermann Bahr was to help promote in the German-language sphere. Between 1896 and 1898, Adolph Donath attempted to build up his position as mediator between the Moderní revue circle and some representatives of Viennese modernism (e.g. Karl Kraus, Peter Altenberg and Felix Rappaport.

    children and adolescents were compared by survey design and data collection mode by calculating predictive margins from regression models. There were no statistically significant differences in sociodemographic characteristics or health indicators between the single-mode control group and any of the mixed-mode survey designs. Differences in sociodemographic characteristics between SAQ-Web and SAQ-paper were found. Web respondents were more likely to be male, have higher levels of education, and higher household income compared with paper respondents. After adjusting for sociodemographic characteristics, only one of the 38 analyzed health indicators showed different prevalence rates between the data collection modes, with a higher prevalence rate for lifetime alcohol consumption among the online-responding adolescents (Pinterview surveys for children and adolescents using a mixed-mode design with Web-based and paper questionnaires. ©Elvira Mauz, Robert Hoffmann, Robin Houben, Laura Krause, Panagiotis Kamtsiuris, Antje Gößwald.

  11. On the annual cycle of the sea surface temperature and the mixed layer depth in the Gulf of Mexico

    Mendoza, V.M.; Villanueva, E.E.; Adem, J. [Centro de Ciencias de la Atmosfera, Universidad Nacional Autonoma de Mexico, UNAM, Mexico, D.F. (Mexico)


    Using an integrated mixed layer model, we carry out a simulation of the annual cycle of the sea surface temperature (SST) and of the mixed layer depth (MLD) in the Gulf of Mexico. We also compute the annual cycle of the entrainment velocity in the deepest region of the Gulf of Mexico. The model is based on the thermal energy equation and on an equation of mechanical and thermal energy balance based on the Kraus-Turner theory; both equation are coupled and are vertically integrated in the mixed layer. The model equations are solved in a uniform grid of 25 km in the Gulf of Mexico, the northwestern region of the Caribbean Sea and the eastern coast of Florida. The surface ocean current velocity and the atmospheric variables are prescribed in the model using observed values. We show the importance of the Ekman pumping in the entrainment velocity. We found that the upwelling plays an important role in increasing the entrainment velocity, producing an important reduction in the SST and diminishing the depth of the mixed layer in the Campeche Bay. In the rest of the Gulf of Mexico the downwelling tends to reduce the entrainment velocity, increasing the SST and the MLD. Comparison of the computed annual cycle of the SST and the MLD with the corresponding observations reported by Robinson (1973) shows a good agreement. In the deepest region of the Gulf of Mexico, the photosynthetic pigment concentration data obtained from the Mexican Pacific Cd-Rom of environmental analysis shows significant correlation with the computed annual cycle of the computed entrainment velocity only in January, April, May, June and September.

    Special Issue on Management This special issue contains seven papers originally presented at an International Workshop on Services for Managing Distributed Systems (SMDS'95), held in September 1995 in Karslruhe, Germany. The workshop was organized to present the results of two ESPRIT III funded projects, Sysman and IDSM, and more generally to bring together work in the area of distributed systems management. The workshop focused on the tools and techniques necessary for managing future large-scale, multi-organizational distributed systems. The open call for papers attracted a large number of submissions and the subsequent attendance at the workshop, which was larger than expected, clearly indicated that the topics addressed by the workshop were of considerable interest both to industry and academia. The papers selected for this special issue represent an excellent coverage of the issues addressed by the workshop. A particular focus of the workshop was the need to help managers deal with the size and complexity of modern distributed systems by the provision of automated support. This automation must have two prime characteristics: it must provide a flexible management system which responds rapidly to changing organizational needs, and it must provide both human managers and automated management components with the information that they need, in a form which can be used for decision-making. These two characteristics define the two main themes of this special issue. To satisfy the requirement for a flexible management system, workers in both industry and universities have turned to architectures which support policy directed management. In these architectures policy is explicitly represented and can be readily modified to meet changing requirements. The paper `Towards implementing policy-based systems management' by Meyer, Anstötz and Popien describes an approach whereby policy is enforced by event-triggered rules.

    quantum registers with five or less qubits. Moreover, about 5-20 MB of working memory is typically needed (in addition to the memory for the Maple environment itself). However, especially when working with symbolic expressions, the requirements on the CPU time and memory critically depend on the size of the quantum registers owing to the exponential growth of the dimension of the associated Hilbert space. For example, complex (symbolic) noise models, i.e. with several Kraus operators, may result in very large expressions that dramatically slow down the evaluation of e.g. distance measures or the final-state entropy, etc. In these cases, Maple's assume facility sometimes helps to reduce the complexity of the symbolic expressions, but more often than not only a numerical evaluation is feasible. Since the various commands can be applied to quite different scenarios, no general scaling rule can be given for the CPU time or the request of memory. References:[1] T. Radtke, S. Fritzsche, Comput.

  18. Coupling alongshore variations in wave energy to beach morphologic change using the SWAN wave model at Ocean Beach, San Francisco, CA (United States)

    Eshleman, Jodi L.; Barnard, Patrick L.; Erikson, Li H.; Hanes, Daniel M.


    Coastal managers have faced increasing pressure to manage their resources wisely over the last century as a result of heightened development and changing environmental forcing. It is crucial to understand seasonal changes in beach volume and shape in order to identify areas vulnerable to accelerated erosion. Shepard (1950) was among the first to quantify seasonal beach cycles. Sonu and Van Beek (1971) and Wright et al. (1985) described commonly occurring beach states. Most studies utilize widest spaced 2-D cross shore profiles or shorelines extracted from aerial photographs (e.g. Winant et al. 1975; Aubrey, 1979, Aubrey and Ross, 1985; Larson and Kraus, 1994; Jimenez et al., 1977; Lacey and Peck, 1998; Guillen et al., 1999; Norcorss et al., 2002) to analyzed systematic changes in beach evolution. But with the exception of established field stations, such as Duck, NC (Birkemeier and Mason, 1984), ans Hazaki Oceanographical Research Station (HORS) in Japan (Katoh, 1997), there are very few beach change data sets with high temporal and spatial resolutions (e.g. Dail et al., 2000; Ruggiero et al., 2005; Yates et al., in press). Comprehensive sets of nearshore morphological data and local in situ measurements outside of these field stations are very rare and virtually non-existent high-energy coasts. Studied that have attempted to relate wave statistics to beach morphology change require some knowledge of the nearshore wave climate, and have had limited success using offshore measurement (Sonu and Van Beek, 1971; Dail et al., 2000). The primary objective of this study is to qualitatively compare spatially variable nearshore wave predictions to beach change measurements in order to understand the processes responsible for a persistent erosion 'hotspot' at Ocean Beach, San Francisco, CA. Local wave measurements are used to calibrate and validate a wave model that provides nearshore wave prediction along the beach. The model is run for thousands of binned offshore wave

  19. Long-term impact of bottom trawling on pelagic-benthic coupling in the southern North Sea (German Bight) (United States)

    were measured on sandy (permeable) and silty (diffusive) sediments, whereas significant differences of microbial O2 uptake were observed indeed between permeable and diffusive sediments. Nevertheless, when considering the multitude of different methods, we found that benthic respiration over the season seemed to be governed mainly by settling of fresh organic matter during calm periods and its rapid turnover in a region where strong tidal and wind-forced currents distribute suspended particles over large areas. Summer pelagic respiration rates were an order of magnitude higher then benthic rates, and account for 88-93% of total respiration, which represents 79-98% of pelagic primary production. Our measurements of benthic respiration account for 7-12% of the total in the German Bight, which is lower compared to earlier studies. Strong tidal and wind-forced currents along with the lack of complex three-dimensional biogenic structures seem to prevent settling of suspended matter and foster resuspension, thereby supporting pelagic turnover processes. Hence, we assume that benthic turnover might have been higher before systematic bottom trawling destroyed the bottom hydrobiological regime. Today, due to the strong current regime in the German Bight, the pelagic system appears to be a largely closed system of production and respiration, with comparably little for export to the benthic system due to absence of biogenic structures.

    , Kognitivismus und Konstruktivismus zur theoretischen Fundierung der Mediendidaktik. Er geht auf Missverständnisse und Probleme in diesem Zusammenhang ein. Als alternative Sichtweise stellen die Autoren eine Interpretation des Pragmatismus von John Dewey vor, der von der Lernsituation ausgeht und einen methodisch orientierten Ansatz anbietet. Damit wird letztlich eine stärkere Verbindung von Theorien der Mediendidaktik und Medienbildung angestrebt. Auch Stefan Krause und Rolf-Dieter Kortmann ziehen die Lerntheorien zur Diskussion der medienbasierten Wissensaneignung heran, sie legen ihren Schwerpunkt aber auf die Frage nach der aktuell diskutierten Problematik der Standardisierung bzw. Standardisierbarkeit von medial aufbereiteten Lerninhalten. Sie beschreiben, wie der Austausch von Inhalten perspektivisch nicht mehr über Datenformate, sondern durch Lernobjekte stattfindet, und diskutieren anhand eines Beispiels die - problematischen - Implikationen für die Mediendidaktik. Einen anderen Impuls gibt der Beitrag von Wolfgang Müskens und Isabel Müskens. Sie verstehen «Provokationen» als methodisches Element einer Didaktik internetgestützter Lernarrangements. «Provoziert» werden soll der Lernende durch einstellungskonträres Material, das letztlich zu einer höheren Individualisierung des Lernens und einer stärkeren Interaktion zwischen Lehrenden und Lernenden führen soll. Die theoretische Begründung solcher provokativen Elemente in einem didaktischen Konzept findet sich im Kompetenzbegriff und in der Systemtheorie, aber auch in psychologischen Ansätzen. In dem zweiten Teil dieser Ausgabe der Online-Zeitschrift geht es insbesondere um den Zusammenhang von Mediendidaktik und Wissensmanagement. Für Gabi Reinmann-Rothmeier handelt es sich bei Wissensmanagement und Mediendidaktik bislang um ein dialektisches Paar. Während Wissensmanagement eher ein Thema für die Betriebswirtschaft war, wurde die Mediendidaktik als eine (Teil-Disziplin der Medienpädagogik verstanden

  7. Invasive cancer cells and metastasis (United States)

    Mierke, Claudia Tanja


    , vinculin and FAK synergize their functions to regulate the mechanical properties of cells such as stiffness and contractile forces. Finally, the knowledge of the mechanical properties of invasive and non-invasive cells could provide a source for future drug developments to inhibit formation of metastases. This special section also includes two papers from the group of Martin Herrmann, a research paper and a review paper. The research paper by Janko et al deals with the cooperative binding of Annexin A5 to phosphatidylserines on apoptotic cell membranes [6]. This could not alone serve as an 'eat me' signal for macrophages as healthy cells also express Annexin A5 on their cell surface. The authors suggest that the cooperative binding is altered and subsequently the fluidity of Annexin A5 on the membrane. Together this may serve as a signal for phagocytic cells to eat apoptotic cells and leave healthy ones untouched. The paper by Biermann et al reviews the role of biophysical signals in the clearance of apoptotic cells [7]. In addition to the acto-myosin cytoskeleton, the keratin network seems to play a role in cancer research. The paper from the Beil and the Marti group demonstrates that microrheology is a valuable tool to determine the viscoelastic properties of polymer networks such as the keratin network in cells and an arbitrary in vitro network [8]. They describe how the topology of the keratin network affects the overall mechanical behavior of cells. It seems that the field of physical oncology will continue to grow in the future and more research will address the mechanical properties of cancer cells and whole tissues. Biophysical methods will need to be further improved and adapted to the needs of cancer research. References [1] Coughlin M F and Fredberg J J 2013 Phys.

    ) used the adaptive optics systems at Keck and Palomar with NIRC2 and PHARO, respectively, and typically observed each target with the J-, H-, and K-band filters. Adams et al. 2012 (Cat. J/AJ/144/42), Adams et al. (2013AJ....146....9A) and Dressing et al. (2014AJ....148...78D) mainly used the Ks filter in their AO observations at the MMT; in addition, they often used the J-band filter when a companion was detected in the Ks image. The field of view of the ARIES instrument on the MMT was 20''*20'', somewhat smaller than that of PHARO at Palomar, and the FWHM of the stellar images varied between about 0.1'' and 0.6''. Kraus et al. 2016 (Cat. J/AJ/152/8) employed adaptive optics imaging and also non-redundant aperture-mask interferometry at Keck with the NIRC2 instrument; the latter technique is limited only by the diffraction limit of the 10m Keck telescope. They used the K' filter for their observations. Baranec et al. 2016 (Cat. J/AJ/152/18) and Ziegler et al. 2016 (AJ accepted, arXiv:1605.03584) observed a sample of KOI host stars at Keck using mostly the K' filter on NIRC2. With the Robo-AO imaging at the Palomar 1.5m telescope, Law et al. 2014 (Cat. J/ApJ/791/35), Baranec et al. 2016 (Cat. J/AJ/152/18), and Ziegler et al. 2016 (AJ accepted, arXiv:1605.03584) covered a total of 3320 KOI host stars. For most observations, they used a long-pass filter whose window starts at 600nm (LP600), which is similar to the Kepler bandpass; they also took data for some stars in the Sloan i-band filter and, more rarely, Sloan r and z filters. The typical FWHM of the observed stellar PSF amounted to 0.12''-0.15''; the images covered a field of view of 44''*44''. Lillo-Box et al. (2012, Cat. J/A+A/546/A10; 2014, Cat. J/A+A/566/A103) used the 2.2m Calar Alto telescope with the AstraLux instrument to obtain diffraction-limited imaging with the lucky imaging technique, typically observing in the i- and z-band filters. This technique involves taking a very large number of short exposures

    to afford imports (Naylor and Falcon 2010). Future changes in agricultural commodity prices tied to yield variations could disproportionately impact the welfare of specific households, while possibly benefiting other lower income countries that produce exports (Hertel et al 2010). In the event that import dependence rises markedly from 16% of the global population circa 2000 (Fader et al 2013), cooperative trade policies may be pivotal to alleviating food insecurity of the most vulnerable net-food importing countries (Bouët and Debucquet 2012). Quantifying the capacity of countries to meet their per capita crop requirements underpins the importance of truly widespread yield improvements, particularly given the already concentrated nature of export production. Fader et al 's study offers new insight on how the growing spatial disconnect between where people live and where food is grown may dictate either increasingly entrenched dependence on foreign production or immense cropland expansion throughout net-importing countries. Framing this challenge in terms of potential domestic crop production reveals that even small yield improvements could go a long way toward easing both.

    results. It seems that the introduction of any radical solutions referring to the inclusion of newly arrived groups produces very poor integration effects. Forcing cultural assimilation by state institutions through the introduction of obligatory integration courses and through giving importance only to socio-economic dimension could be just as deflating as the granting of special cultural rights and recognition of cultural difference through multiculturalist policies and ignoring importance of socio-economic dimension of integration. Since recently there have been discussions about the connections between the politics of recognition and the politics of redistribution, it could be assumed that the multiculturalism backlash stems from economic rather than ideological reason. However, research findings do not confirm that the introduction of multiculturalist policies affects the weakening of the welfare state. But, on the contrary, there are findings that show how multiculturalism policy combined with generous welfare state could cause poor integration outcomes. Many theoretical research (Banting and Kymlicka, 2004; Banting et al., 2006; Entzinger, 2006; Evans, 2006; Kraus and Schönwälder, 2006; Miller, 2008 question the connections between ethnic diversity, multiculturalism and the welfare state. However, there are few studies that explain how multicultural policies linked with generous welfare state influence immigrant integration. The findings of many studies dealing with the influence of multicultural policies on the welfare state suggest that the very multicultural policies are not responsible for the weakening of the welfare state and for reducing the allocation of funds for social purposes (Banting and Kymlicka, 2004; Banting et al., 2006; Evans, 2006; Entzinger, 2006; Miller, 2008. In the study of twenty-three types of multiculturalist policies, Banting et al. (2006 tested whether countries with more developed multiculturalist policies faced impoverishment and

    . Maximow (27) showed that bovine bacilli even in small numbers cause the death of cells in tissue cultures of rabbit lymph nodes whereas the BCG or the human bacillus may accumulate within the cells in tremendous numbers without injuring them. Nevertheless in the liver, spleen and bone marrow of the living animal, caseation does not appear at the time when bovine bacilli are most abundant, but after they have been greatly reduced in numbers. Large numbers of the less virulent types of tubercle bacilli accumulated in different organs a short time after infection do not cause caseation, and with the bovine infection caseation under the same conditions occurs only in the lung. Later when the animal is sensitized caseation occurs in various organs in the presence of the small numbers of tubercle bacilli that remain in the tissues after most of them have been destroyed, and the extent of this caseation varies with the numbers of residual bacilli. These observations suggest that a large number of bacilli fail to cause necrosis soon after infection whereas a few bacilli produce caseation in the animal that is sensitized. Many investigators have held that caseation is due to sensitization. Krause (28), Huebschman (29) and Pagel (30) think that caseation is caused by the action of tuberculin-like substances on the sensitized tissues of the allergic animal. Rich and McCordock (31) view the process in essentially the same light. Recently Schleussing (32) has suggested that caseation is a coagulation necrosis in Weigert's sense of an allergically inflamed tissue, and is similar to the necrosis of the Arthus phenomenon.
