    1984-01-01

    We presented a patient with a deforming and necrotizing syndrome of the nasal pyramid. The histopathology demonstrated a lymphoma. The original works of Weiss are related. The diseases is characterized by: ecotaxis of the nasal pyramid, localized persistency during a long time, malaise in advanced studies and sensibility to radiations. We proposed the name linfoma histiocitico maligno nasal de Weiss and consider it as a autonomous entity.

    It was with great sadness that we learned that our colleague and friend Mario Weiss passed away on February 11th. A feeling of emptiness overtook us all. Mario was a reassuring reference in the small community of linear accelerator experts, as he continued to come to CERN regularly and discuss accelerator problems with passion for many years after his official retirement. Mario came to CERN in 1960 and in the PS Division worked on beam dynamics of low-energy high-intensity proton beams, soon becoming a world-level expert in the field. He took an active part in the construction of Linac2, where he was responsible for the low-energy beam transport system. In the early 80’s he turned his interest to the Radio Frequency Quadrupole (RFQ), a novel concept for acceleration which allows the problems related with bunching and injecting low-energy beams to be overcomed. After starting a fruitful collaboration with the Los Alamos scientists, ...

  8. Relations between adolescent ratings of Rothbart's temperament questionnaire and the HEXACO personality inventory.

    Science.gov (United States)

    Farrell, Ann H; Brook, Christina; Dane, Andrew V; Marini, Zopito A; Volk, Anthony A

    2015-01-01

    Conventionally, individual differences have been assessed using temperament measures for infants and children, and personality measures for adults. We chose to explore both temperament and personality to see whether a convergence exists specifically during adolescence. A sample of 225 adolescents completed Rothbart's Early Adolescent Temperament Questionnaire-Revised (EATQ-R), a 4-factor temperament scale, and the HEXACO Personality Inventory-Revised (HEXACO PI-R), a 6-factor personality scale. As hypothesized, we found significant relations between the 2 measures. However, there were some important differences between the 2 measures regarding Honesty-Humility, Openness, and Frustration that highlight the unique contributions of both instruments to understanding and measuring adolescent individual differences. As there is a relatively scant history of measuring temperament or personality in adolescence, it is sometimes difficult for researchers to decide which instrument is most appropriate. The results reported here suggest that either the EATQ-R or the HEXACO PI-R could be appropriate, depending on the specific research questions being asked.

  9. Mallory-Weiss Tear during Esophagogastroduodenoscopy

    2015-02-01

    Full Text Available Mallory-Weiss tears (MWTs are mucosal lacerations caused by forceful retching and are typically located at the gastroesophageal junction. Reported cases of MWT with serious complications seen in esophagogastroduodenoscopy are limited. We report MWT in an 81-year-old woman who presented with gastric perforation by esophagogastroduodenoscopy. We discuss and indicate that hiatal hernia, atrophic gastritis and old age may be associated with the gastric perforation in comparison to typical tears occurring at the gastroesophageal junction.

  13. Temperamento de crianças na abordagem de Rothbart: estudo de revisão sistemática

    Directory of Open Access Journals (Sweden)

    Maria Beatriz Martins Linhares

    2013-12-01

    Full Text Available O temperamento é definido pelas diferenças individuais na reatividade e autorregulação, tendo composição biológica e podendo ser influenciado pelo ambiente. O modelo psicobiológico de Mary Rothbart tem sido amplamente utilizado no estudo do temperamento. O objetivo desse estudo foi revisar sistematicamente a literatura indexada publicada nos anos de 2008 a 2011 que trata do temperamento de crianças no período do nascimento até a idade escolar, de acordo com a abordagem de Rothbart. As bases de dados utilizadas foram PubMed, PsycINFO, Scielo e Lilacs. Foram encontrados 25 artigos, os quais foram analisados por três pesquisadores quanto aos aspectos objetivo, amostra, instrumentos, resultados e conclusões. As amostras dos estudos foram predominantemente crianças norte-americanas (48% e europeias (32%, avaliadas, em sua maioria, nos primeiros três anos de idade. A maioria dos estudos (92% avaliou o temperamento da criança por meio de questionários de heterorrelato, sendo as mães as principais informantes. Os resultados mostraram, de um lado, a relação entre temperamento e indicadores biológicos da criança (oito estudosm e de outro, a associação entre temperamento e características do contexto familiar (sete estudos. A relação entre temperamento e características do comportamento ou personalidade foi encontrada em quatro estudos. Os demais estudos mostraram associação entre temperamento e transtornos/síndromes, contexto familiar/escolar ou nível socioeconômico/imigração. Nos achados verificou-se que o temperamento nas fases iniciais de desenvolvimento da criança, de acordo com o modelo de Rothbart, mostrou associação com características da personalidade, problemas de comportamento e psicopatologias, podendo ser moderado por interações com o ambiente familiar.

  14. Babinski-Nageotte's syndrome and Hemimedullary (Reinhold's) syndrome are clinically and morphologically distinct conditions.

    Science.gov (United States)

    Krasnianski, Michael; Neudecker, Stephan; Schluter, Andreas; Zierz, Stephan

    2003-08-01

    A hemimedullary infarction, in which medial and lateral medullary lesions occur simultaneously, is a rare cerebrovascular disease. It has been suggested that the Babinski-Nageotte's syndrome is the classical brainstem syndrome that corresponds to hemimedullary lesion. In this study we compare clinical symptoms and magnetic resonance imaging (MRI) data of two patients exhibiting classical Babinski-Nageotte's syndrome according to the original description with symptoms and MRI data of a patient with clinically complete hemimedullary lesion. Our study shows that Babinski-Nageotte's syndrome is neither clinically nor on MRI identical with hemimedullary lesion. Hypoglossal palsy, an invariable symptom of hemimedullary syndrome, is not part of the Babinski-Nageotte's syndrome according to the original description. Consistent with the original historical report, Babinski- Nageotte's syndrome is a lateral "Wallenbergian" medullary lesion with a spreading of the lesion to the more basal localised pyramidal tract. The clinical features of the hemimedullary syndrome, described in 1894 by Reinhold, and the MRI appearances in our patient with this syndrome are clearly different from other classical brainstem syndromes and should be called Reinhold's syndrome.

    2011-03-01

    We present the results of extensive simulations regarding the critical behavior at the endpoint of the Roberge-Weiss transition for Nf=2 QCD. We confirm early evidence, presented in Ref. [M. D’Elia and F. Sanfilippo, Phys. Rev. DPRVDAQ1550-799810.1103/PhysRevD.80.111501 80, 111501(R) (2009).], according to which the Roberge-Weiss endpoint is first order in the limit of large or small quark masses, and second order for intermediate masses. A systematic study of the transition strength as a function of the quark mass in the first order regions, permits us to estimate the tricritical values of the quark mass separating the second order region from the first order ones.

    1983-01-01

    A simple derivation of parabolic 1/εr-T curves is obtained by reconsidering the origin of the dielectric Curie-Weiss law. The only assumption needed is the introduction of a non-linear temperature dependance of the macroscopic dielectric polarization in the macroscopic Clausius-Mossotti equation

  18. Signature of tilted Dirac cones in Weiss oscillations of 8 -P m m n borophene

    Science.gov (United States)

    Islam, SK Firoz; Jayannavar, A. M.

    2017-12-01

    Polymorph of 8 -P m m n borophene exhibits anisotropic tilted Dirac cones. In this work, we explore the consequences of the tilted Dirac cones in magnetotransport properties of a periodically modulated borophene. We evaluate modulation-induced diffusive conductivity by using linear response theory in low temperature regime. The application of weak spatial modulation (electric, magnetic or both) gives rise to the magnetic-field-dependent nonzero oscillatory drift velocity which causes Weiss oscillation in the longitudinal conductivity at low magnetic field. The Weiss oscillation is studied in the presence of a weak spatial electric, magnetic, and both modulations individually. The tilting of the Dirac cones gives rise to an additional contribution to the Weiss oscillation in longitudinal conductivity. Moreover, it also enhances the frequency of the Weiss oscillation and modifies its amplitude too. Most remarkably, it is found that the presence of both out-of-phase electric and magnetic modulations can cause a sizable valley polarization in diffusive conductivity. The origin of valley polarization lies in the opposite tilting of the two Dirac cones at two valleys.

  1. CHRISTIAN PHILOSOPHERS OF THE WEST ABOUT THE “COLD WAR”, TOTALITARIANISM AND COMMUNISM: COMPARATIVE ANALYSIS OF REINHOLD NIEBUHR’S AND GIORGIO LA PIRA’S CONCEPTS

    Directory of Open Access Journals (Sweden)

    T. V. Zonova

    2012-01-01

    Full Text Available The author examines the legacy of two great Christian thinkers, the American Reinhold Niebuhr and the Italian Giorgio La Pira, both very influential during the Cold War. Niebuhr was a Protestant theologian and political adviser to the American establishment. The Mayor of Florence, La Pira, was a prominent Italian statesman and an eminent Catholic thinker. The author analyzes their views on international relations, in particularly on the western policy towards the Soviet Union, the use of nuclear weapons, the war in Vietnam and communism. The legacy of two thinkers is highly topical in front of the ethical dimension of choices needed in international politics today.

  2. Misjudging frustrations in spin liquids from oversimplified use of Curie-Weiss law

    Absence of a single smoking-gun experiment to identify a quantum spin liquid, has kept their characterisation difficult till date. Featureless dc magnetic susceptibility and large antiferromagnetic frustration are always considered as the essential pointers to these systems. However, we show that the amount of frustration estimated by using generalised Curie-Weiss law on these susceptibility data are prone to errors and thus should be dealt with caution. We measure and analyse susceptibility data of Ba{sub 3}ZnIr{sub 2}O{sub 9}, a spin orbital liquid candidate and Gd{sub 2}O{sub 3}, a 1.5 K antiferromagnet and show the distinguishing features between them. A continuous and significant change in Curie and Weiss constants is seen to take place in Ba{sub 3}ZnIr{sub 2}O{sub 9} and other reported spin liquids with the change in the range of fitting temperatures showing the need of a temperature ‘range-of-fit’ analysis before commenting on the Weiss constants of spin liquids. The variation observed is similar to fluctuations among topological sectors persisting over a range of temperature in spin-ice candidates. On the other hand, even though we find correlations to exist at even 100 times the ordering temperature in Gd{sub 2}O{sub 3}, no such fluctuation is observed which may be used as an additional distinguishing signature of spin liquids over similarly featureless correlated paramagnets. - Highlights: • Curie-Weiss fitting may give erroneous frustration parameters in spin-liquids. • The results depend upon choice of fitting method and temperature range used. • More appropriate method is to use a ʽrange of fit’ analysis. • Can distinguish between spin-liquids and correlated paramagnets.

    Corral, Juan E; Keihanian, Tara; Kröner, Paul T; Dauer, Ryan; Lukens, Frank J; Sussman, Daniel A

    2017-04-01

    Hiatal hernia is considered to be a predisposing factor to develop Mallory-Weiss Syndrome (MWS). No large case-control studies verifying this hypothesis have been conducted. We reviewed all esophagogastroduodenoscopies with findings of MWS (n = 2342) in a national database and compared with age and gender-matched controls (n = 9368). Demographics, endoscopic characteristics and presence of a hiatal hernia were compared between both groups. Average age was 56.7 ± 18.6 years, and 72.4% were male. Hiatal hernia was more common in controls, and no significant difference was seen in a multivariate analysis. Dynamic changes inducing mucosal tension are more relevant determinants to develop MWS than gastro-esophageal junction location alone.

    Although, trauma, foot deformity (pesplanovalgus), systemic diseases such as diabetes mellitus and lupus, drugs (steroids, antineoplastic) and excessive alcohol consumption have all been accused in the etiology of avascular necrosis of the tarsal bones, spontaneous avascular necrosis of the navicular bone, especially in adults, is a rare entity. In this article, we report a 50-year-old female patient with bilateral, spontaneous avascular necrosis of the navicular bone and related severe talonavicular arthrosis. Clinical and radiological findings were concordant with Müller-Weiss disease, which is a rare disease with complex idiopathic foot condition of the adult tarsal navicular bone characterized by progressive navicular fragmentation and talonavicular joint destruction. The patient was successfully treated with two-staged bilateral talonavicular arthrodesis.

  8. System approaches of Weiss and Bertalanffy and their relevance for systems biology today.

    Science.gov (United States)

    Drack, Manfred; Wolkenhauer, Olaf

    2011-06-01

    System approaches in biology have a long history. We focus here on the thinking of Paul A. Weiss and Ludwig von Bertalanffy, who contributed a great deal towards making the system concept operable in biology in the early 20th century. To them, considering whole living systems, which includes their organisation or order, is equally important as the dynamics within systems and the interplay between different levels from molecules over cells to organisms. They also called for taking the intrinsic activity of living systems and the conservation of system states into account. We compare these notions with today's systems biology, which is often a bottom-up approach from molecular dynamics to cellular behaviour. We conclude that bringing together the early heuristics with recent formalisms and novel experimental set-ups can lead to fruitful results and understanding. Copyright © 2011 Elsevier Ltd.

    Crouzon syndrome (MIM 123500) is a common autosomal dominant form of craniosynostosis with shallow orbits, ocular proptosis, and maxillary hypoplasia. Jackson-Weiss syndrome (MIM 123150) is another autosomal dominant craniosynostosis with highly variable phenotypic expression. Unlike Crouzon syndrome, Jackson-Weiss syndrome is associated with foot anomalies. The authors performed two point linkage and haplotype analyses using 13 dinucleotide repeat markers on chromosome 10, spanning a genetic distance of 108 cM. The Crouzon syndrome locus (CFD1) maps to the region of chromosome 10q2 with the tightest linkage to locus D10S205 (Z = 3.09, {theta} = 0.00). The Jackson-Weiss syndrome locus in the large Amish pedigree in which the condition was originally described was also linked to the chromosome 10q23-q26 region between loci D10S190 and D10S186. The D10S209 locus was most strongly linked (Z = 11.29, {theta} = 0.00). 29 refs., 2 figs., 2 tabs.

    Full Text Available Zum Sprachgebrauch Fr. R. Kreutzwalds anhand seiner Beiträge in der Wochenschrift „Das Inland“ Zusammenfassung Im vorliegenden Aufsatz wird der Sprachgebrauch Friedrich Reinhold Kreutzwalds anhand seiner Beiträge in der Wochenschrift „Das Inland“ betrachtet. Zuerst wird ein kurzer Überblick über Kreutzwald als Mitarbeiter des „Inlands“ gegeben, danach geht man auf die Behandlung seiner Sprache ein. Die Autoren und Herausgeber des deutschsprachigen „Inlands“ waren in der Regel Deutschbalten, deren Muttersprache Deutsch war. Mit Kreutzwald verhält es sich anders. Er war ein gebürtiger Este, der sich die deutsche Sprache angeeignet hatte. Seine Bildung von der Grundschule bis zum Abschluss der Universität hatte er in deutscher Sprache erhalten. Dieser Umstand gibt Anlass zur Frage, ob in Kreutzwalds deutscher Sprache Merkmale vorkommen, die seine estnische Herkunft verraten. Bei der Analyse des Sprachgebrauchs von Kreutzwald werden folgende Ebenen des Sprachsystems berücksichtigt: Lexik (Wortwahl, Grammatik (Morphologie und Syntax und Stilfiguren, vorwiegend Mittel der Bildlichkeit. Da die untersuchten Texte etwa 170 Jahre alt sind, ist es selbstverständlich, dass in ihnen Wörter und Wendungen vorkommen, die heute als veraltet oder altertümlich gelten. Neben dem veralteten Wortgut benutzt Kreutzwald recht viele Wörter und Wendungen, die der gehobenen Stilschicht angehören. Wörter aus den so genannten niederen Stilschichten kommen in Kreutzwalds Schriften bedeutend seltener vor. Wider Erwarten erscheint ausgesprochenes deutschbaltisches Wortgut in der Publizistik von Kreutzwald kaum. Hervorzuheben sind aber okkasionelle Bildungen von Kreutzwald. Da es nicht für jeden estnischen Begriff oder jedes estnische Wort eine adäquate deutsche Entsprechung gab, musste Kreutzwald selbst neue Wörter bilden. Im Bereich der Morphologie gibt es nicht viele Besonderheiten. Ein typisches Merkmal ist die Bevorzugung der Formen, die

  14. From the other side of doubt – overcoming anxiety and fear: Paul Tillich’s “courage to be” and Reinhold Niebuhr’s “Christian realism”

    Directory of Open Access Journals (Sweden)

    Yolanda Dreyer

    2004-11-01

    Full Text Available Paul Tillich’s view on reality is that anxiety is part of being human. According to Reinhold Niebuhr, Christian realism has a realistic and an idealistic side to it. Reality is always changing and filled with tension. On the other hand there is a vision of otherworldliness, a vision of transcendence in everydayness. The theological nomer “Christian” indicates an awareness of God’s presence as well as the human tendency to be self-directed. The objectives of this article are to “rephrase” Niebuhr’s knowledge of the reality of the secular world, conceptualise Tillich’s categories of “anxiety” and “fear” against the background of the reality of the secular world, and explain Niebuhr’s notion of “Christian realism”. Their insights are used to empower the church to overcome homophobia in the faith community’s pastoral care of gays.

    In this article, we review how two eminent Viennese system thinkers, Paul A Weiss and Ludwig von Bertalanffy, began to develop their own perspectives toward a system theory of life in the 1920s. Their work is especially rooted in experimental biology as performed at the Biologische Versuchsanstalt, as well as in philosophy, and they converge in basic concepts. We underline the conceptual connections of their thinking, among them the organism as an organized system, hierarchical organization, and primary activity. With their system thinking, both biologists shared a strong desire to overcome what they viewed as a “mechanistic” approach in biology. Their interpretations are relevant to the renaissance of system thinking in biology—“systems biology.” Unless otherwise noted, all translations are our own. PMID:18217527

    We study the large deviations of the magnetization at some finite time in the Curie-Weiss random field Ising model with parallel updating. While relaxation dynamics in an infinite-time horizon gives rise to unique dynamical trajectories [specified by initial conditions and governed by first-order dynamics of the form m_{t+1}=f(m_{t})], we observe that the introduction of a finite-time horizon and the specification of terminal conditions can generate a host of metastable solutions obeying second-order dynamics. We show that these solutions are governed by a Newtonian-like dynamics in discrete time which permits solutions in terms of both the first-order relaxation ("forward") dynamics and the backward dynamics m_{t+1}=f^{-1}(m_{t}). Our approach allows us to classify trajectories for a given final magnetization as stable or metastable according to the value of the rate function associated with them. We find that in analogy to the Freidlin-Wentzell description of the stochastic dynamics of escape from metastable states, the dominant trajectories may switch between the two types (forward and backward) of first-order dynamics. Additionally, we show how to compute rate functions when uncertainty in the quenched disorder is introduced.

    Peculiarities of applying the Curie-Weiss law to the analysis of the magnetic susceptibility of the impurities of the rare earth elements in the IV-VI crystals are examined. It is shown that the traditional approach to the determination of the paramagnetic Curie temperature of ferromagnets and antiferromagnets applied to the impurities of ferromagnetic and antiferromagnetic elements in the doped crystal may lead to fundamental mistakes. The results of this examination are used to analyze the high temperature magnetic susceptibility of Eu and Gd impurities in the PbTe doped crystals grown from the melt using the Bridgman method. It is established that the doping of PbTe with Eu leads to the formation of ferromagnetic inclusions and the same doping with Gd leads to the formation of antiferromagnetic inclusions in the crystal. It is shown that these inclusions are most likely the complexes based on the europium or gadolinium oxides EuO and Gd{sub 2}O{sub 3}, respectively.

    This work reports an attempt to quantify the purities of powders of high-purity organic compounds with stable nitroxyl radicals (namely, 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO), 1-oxyl-2,2,6,6-tetramethyl-4-hydroxypiperidine (TEMPOL), and 4-hydroxy-2,2,6,6-tetramethylpiperidine 1-oxyl benzoate (4-hydroxy-TEMPO benzoate)) in terms of mass fractions by using our “effective magnetic moment method,” which is based on both the Curie–Weiss law and a fundamental equation of electron paramagnetic resonance (ESR). The temperature dependence of the magnetic moment resulting from the radicals was measured with a superconducting quantum interference device magnetometer. The g value for each compound was measured with an X-band ESR spectrometer. The results of the purities were (0.998 ± 0.064) kg kg{sup −1} for TEMPO, (1.019 ± 0.040) kg kg{sup −1} for TEMPOL, and (1.001 ± 0.048) kg kg{sup −1} for 4-hydroxy-TEMPO benzoate. These results demonstrate that this analytical method as a future candidate of potential primary direct method can measure the purities with expanded uncertainties of approximately 5%.

    Full Text Available Background and Aim. In some cases of iatrogenic Mallory-Weiss tears (MWTs, hemostasis is needed due to severe mucosal tearing with bleeding. Therefore, we aimed to evaluate the risk factors for severe iatrogenic MWTs and the methods of endoscopic bleeding control. Materials and Methods. Between January 2008 and December 2012, 426,085 cases of screening upper endoscopy were performed at the Asan Medical Center. We retrospectively analyzed the risk factors for severe iatrogenic MWTs requiring an endoscopic procedure and the treatment modalities of bleeding control. Results. Iatrogenic MWTs occurred in 546 cases (0.13% of screening upper endoscopy in 539 patients. Bleeding control due to severe bleeding was applied in 71 cases (13.0%, and rebleeding after initial bleeding control occurred in 1 case. Multivariate analysis showed that old age, a history of distal gastrectomy, and a less-experienced endoscopist (fewer than 2,237.5 endoscopic procedures at the time of the MWT were associated with severe iatrogenic MWTs requiring an endoscopic procedure. Among 71 cases requiring bleeding control, a hemoclip was used in 81.7% (58 cases. Conclusions. Screening endoscopy procedures should be carefully performed when patients are in their old age and have a history of distal gastrectomy, particularly if the endoscopist is less experienced.

    Craniosynostosis is a common malformation consisting of premature fusion of skull bones leading to abnormal head shape and, in severe cases, increased intracranial pressure. Crouzon (CFD1) and Jackson-Weiss syndromes (JWS) are two distinct autosomal dominant craniosynostotic conditions with ocular proptosis and maxillary hypoplasia. In the former condition, the proptosis tends to be more severe and is due to shallow orbits. Unlike CFD1, JWS is associated with foot anomalies and highly variable phenotypic expression. We performed two point linkage and haplotype analyses with 15 markers on chromosome 10, spanning a genetic distance of 108 cM. The CFD1 locus maps to the chromosome 10q23-26 region with tightest linkage to D10S205 (Z=3.09, {theta}=0.00, 19 meioses). The JWS locus (originally described in this family) was also linked to this region in an 18 cM interval between D10S190 and D10S186. The D10S209 locus was most strongly linked (Z=11.29, {theta}=0.00, 40 meioses). All of the markers had recombinants with at least one of the conditions. Regional candidate genes implicated in craniofacial and limb development include HOX11, PAX2, ZNF32, and RBP3. These disorders may be allelic, but our data raised the possibility of genetic heterogeneity. As we gather more families, we will find evidence for or against the presence of genetically distinct forms of both syndromes. Isolation of the craniosynostotic gene(s) on chromosome 10 will be important for accurate diagnosis of these disorders and identification of genetic factors involved in craniofacial development.

Weiss, der hierfür gewonnen werden konnte, bildete sich zunächst an der Bergakademie Freiberg weiter aus, wobei er die Lehre des führenden Mineralogen A. G. Werner voll in sich aufnahm. Im Verlaufe der Mitarbeit an der Übersetzung gelangte Weiss gegenüber den atomistischen Vorstellungen Haüys zu Ansichten über die Gesetzmäßigkeiten des Kristallbaues. die sich auf Kants Naturphilosophie gründeten. Mit Haüy, den er in Paris näher kennen lernte, kam es deshalb zum Bruch. Seine "dynamische" Kristallographie baute Weiss mathematisch aus und vermochte bereits weit in die Gesetzmäßigkeiten des Kristallbaues einzudringen. Dadurch schuf er die Voraussetzungen für seine Berufung auf den für Karsten vorgesehenen Berliner Mineralogie-Lehrstuhl, der durch dessen frühen Tod frei wurde. doi:10.1002/mmng.20000030102x

  5. FGFR2 exon IIIa and IIIc mutations in Crouzon, Jackson-Weiss, and Pfeiffer syndromes: Evidence for missense changes, insertions, and a deletion due to alternative RNA splicing

    Fibroblast growth factor receptor 2 (FGFR2) mutations have been associated with the craniosynostotic conditions Crouzon, Jackson-Weiss, and Pfeiffer syndromes. Previously, mutations were described in the exons IIIa and IIIc, which form the extracellular, third immunoglobulin-like domain (IgM) and adjacent linker regions, both of which are normally involved in ligand binding. For all three conditions, mutations were found in exon IIIc. Only in Crouzon syndrome were mutations identified in exon IIIa. In this study, 39 cases with one of these three conditions were screened for exon IIIa or IIIc mutations. Eleven mutations are reported in 17 unrelated cases. Mutations in exon IIIa are identified for not only Crouzon but also Jackson-Weiss and Pfeiffer syndromes. Four mutations in either exon IIIa or exon IIIc reported only in Crouzon syndrome are present also in one of the other two syndromes. Two insertions, one in exon IIIa in a Crouzon syndrome patient and the other in exon IIIc in a Pfeiffer syndrome patient, were observed. The latter mutation has the same alternative RNA splicing effect as a reported synonymous mutation for Crouzon syndrome. A missense mutation was detected in one Pfeiffer syndrome family in which two members had craniosynostosis without limb anomalies. The inter- and intrafamilial variability in expression of FGFR2 mutations suggests that these three syndromes, presumed to be clinically distinct, are instead representative of a spectrum of related craniosynostotic and digital disorders. 16 refs., 3 figs., 1 tab.

    Mallory-Weiss syndrome (MWS) accounts for 6-14% of all cases of upper gastrointestinal bleeding. Prognosis of patients with MWS is generally good, with a benign course and rare recurrence of bleeding. However, no strict recommendations exist in regard to the mode of action after a failure of primary endoscopic hemostasis. We report a case of an 83-year-old male with MWS and rebleeding after the initial endoscopic treatment with epinephrine and clips. The final endoscopic control of bleeding was achieved by a combined application of clips and a nylon snare in a "tulip-bundle" fashion. The patient had an uneventful postprocedural clinical course and was discharged from the hospital five days later. To the best of our knowledge, this is the first case report showing the "tulip-bundle" technique as a rescue endoscopic bleeding control in the esophagus.

    We describe the clinical and radiological manifestations of the Jackson-Weiss syndrome (JWS) in a large South Australian kindred. Radiological abnormalities not previously described in the hands include coned epiphyses, distal and middle phalangeal hypoplasia, and carpal bone malsegmentation. New radiological findings in the feet include coned epiphyses, hallux valgus, phalangeal, tarso-navicular and calcaneo-navicular fusions, and uniform absence of metatarsal fusions. Absence of linkage to eight markers along the short arm of chromosome 7 excluded allelian between JWS and Saethre-Chotzen syndrome at 7p21. No linkage was detected to D5S211, excluding allelism to another recently described cephalosyndactyly syndrome mapping to 5qter. 35 refs., 5 figs., 4 tabs.

    Saethre-Chotzen, Crouzon, and Jackson-Weiss syndromes are craniosynostotic autosomal dominant conditions with a wide variability in expression. Saethre-Chotzen has been mapped to chromosome 7p by L. A. Brueton et al., the Greig cephalopolysyndactyly gene was identified at 7p13 by A. Vortkamp et al., and many cases of craniosynostosis have been associated with 7p deletions. The authors confirmed linkage of the Saethre-Chotzen syndrome locus to chromosome 7p. The tightest linkage was to locus D7S493 (7 = 5.04, [theta] = 0.00), and linkage and haplotype analyses refined the location of the gene to the region between D7S513 and D7S516. Jackson-Weiss and Crouzon syndrome loci were analyzed using markers spanning the entire 7p arm and were excluded, proving that they are nonallelic to Saethre-Chotzen, Greig cephalopolysyndactyly, and the del(7p) syndromes. 29 refs., 1 fig., 2 tabs.

    The Weiss Functional Impairment Rating Scale-Parent Form (WFIRS-P) is a 50-item scale that assesses functional impairment on six clinically relevant domains typically affected in attention-deficit/hyperactivity disorder (ADHD). As functional impairment is central to ADHD, the WFIRS-P offers potential as a tool for assessing functional impairment in ADHD. These analyses were designed to examine the overall performance of WFIRS-P in differentiating ADHD and non-ADHD cases using receiver operating characteristics (ROC) analysis. This is the first attempt to empirically determine the level of functional impairment that differentiates ADHD children from normal controls. This observational study comprised 5-19-year-olds with physician-diagnosed ADHD (n = 476) and non-ADHD controls (n = 202). ROC analysis evaluated the ability of WFIRS-P to discriminate between ADHD and non-ADHD, and identified a WFIRS-P cut-off score that optimises correct classification. Data were analysed for the complete sample, for males versus females and for participants in two age groups (5-12 versus 13-19 years). Area under the curve (AUC) was 0.91 (95% confidence interval 0.88-0.93) for the overall WFIRS-P score, suggesting highly accurate classification of ADHD distinct from non-ADHD. Sensitivity (0.83) and specificity (0.85) were maximal for a mean overall WFIRS-P score of 0.65, suggesting that this is an appropriate threshold for differentiation. DeLong's test found no significant differences in AUCs for males versus females or 5-12 versus 13-19 years, suggesting that WFIRS-P is an accurate classifier of ADHD across gender and age. When assessing function, WFIRS-P appears to provide a simple and effective basis for differentiating between individuals with/without ADHD in terms of functional impairment.

    Full Text Available Cet article analyse les idées et l’œuvre de la directrice de l’École des mères, Augusta Moll-Weiss. Dans le contexte du tournant des XIXe-XXe siècles où l’éloge de la ménagère est un thème récurrent des discours moralisateurs émanant des ouvriers ou des bourgeois, Augusta Moll-Weiss met en place un projet de cours ménagers. Son œuvre offre une approche singulière de ce que des activités reconnues comme typiquement féminines peuvent offrir aux femmes. Loin de former uniquement des « fées du logis », les cours professés à l’École des mères donnent aussi aux élèves la possibilité de se préparer à une carrière professionnelle. Augusta Moll-Weiss imagine alors pléthore de débouchés qui placent les activités « du souci des autres » dans la sphère du travail social. Son engagement en faveur de l’enseignement ménager s’accompagne d’une réflexion sur de nouveaux modèles domestiques susceptibles d’accompagner l’entrée des femmes sur le marché du travail. La rationalisation et le partage sexué des tâches domestiques ainsi que la question du temps partiel sont au cœur de son projet. Aux marges de la philanthropie et du féminisme, Augusta Moll-Weiss s’engage donc dans une stratégie de reconnaissance du rôle des femmes dans l’espace civique.

    Craniosynostosis (premature fusion of the skull sutures) occurs as a clinically heterogeneous group of disorders, frequently involving digital abnormalities. The authors have previously provisionally assigned the gene for one such condition, Saethre-Chotzen syndrome (ACS III), to chromosome 7p. Linkage analysis is now reported between ACS III and dinucleotide repeat loci on distal 7p. The maximum lod scores, Z[sub max], were 5.57 at a recombination fraction of .05, with D7S488, and 4.74 at a recombination fraction of .05, with D7S493. Only weak linkage, not reaching significance, was found with distal markers (D7S513 and afm281vc9) and a proximal marker (D7S516). Multipoint analysis shows that the disease locus lies between D7S513 and D7S516. Analysis of individual recombinants shows that the most likely position is between D7S493 and D7S516. Linkage data in regard of Jackson-Weiss syndrome demonstrate that this autosomal dominant form of acrocephalosyndactyly does not map to the ACS III region on 7p or to the acrocephalosyndactyly locus on 5q (Boston type). These findings underline the genetic heterogeneity among the different clinical conditions manifesting with acrocephalosyndactyly. 20 refs., 3 figs., 2 tabs.

  6. Weiss mean-field approximation for multicomponent stochastic spatially extended systems

    Science.gov (United States)

    Kurushina, Svetlana E.; Maximov, Valerii V.; Romanovskii, Yurii M.

    2014-08-01

    We develop a mean-field approach for multicomponent stochastic spatially extended systems and use it to obtain a multivariate nonlinear self-consistent Fokker-Planck equation defining the probability density of the state of the system, which describes a well-known model of autocatalytic chemical reaction (brusselator) with spatially correlated multiplicative noise, and to study the evolution of probability density and statistical characteristics of the system in the process of spatial pattern formation. We propose the finite-difference method for the numerical solving of a general class of multivariate nonlinear self-consistent time-dependent Fokker-Planck equations. We illustrate the accuracy and reliability of the method by applying it to an exactly solvable nonlinear Fokker-Planck equation (NFPE) for the Shimizu-Yamada model [Prog. Theor. Phys. 47, 350 (1972), 10.1143/PTP.47.350] and nonlinear Fokker-Planck equation [Desai and Zwanzig, J. Stat. Phys. 19, 1 (1978), 10.1007/BF01020331] obtained for a nonlinear stochastic mean-field model introduced by Kometani and Shimizu [J. Stat. Phys. 13, 473 (1975), 10.1007/BF01013146]. Taking the problems indicated above as an example, the accuracy of the method is compared with the accuracy of Hermite distributed approximating functional method [Zhang et al., Phys. Rev. E 56, 1197 (1997), 10.1103/PhysRevE.56.1197]. Numerical study of the NFPE solutions for a stochastic brusselator shows that in the region of Turing bifurcation several types of solutions exist if noise intensity increases: unimodal solution, transient bimodality, and an interesting solution which involves multiple "repumping" of probability density through bimodality. Additionally, we study the behavior of the order parameter of the system under consideration and show that the second type of solution arises in the supercritical region if noise intensity values are close to the values appropriate for the transition from bimodal stationary probability density for the order parameter to the unimodal one.

    2017-06-01

    Particle-hole symmetry in the lowest Landau level of the two-dimensional electron gas requires the electrical Hall conductivity to equal ±e2/2 h at half filling. We study the consequences of weakly broken particle-hole symmetry for magnetoresistance oscillations about half filling in the presence of an applied periodic one-dimensional electrostatic potential using the Dirac composite fermion theory proposed by Son [Son, Phys. Rev. X 5, 031027 (2015), 10.1103/PhysRevX.5.031027]. At fixed electron density, the oscillation minima are asymmetrically biased towards higher magnetic fields, while at fixed magnetic field the oscillations occur symmetrically as the electron density is varied about half filling. We find an approximate "sum rule" obeyed for all pairs of oscillation minima that can be tested in experiment. The locations of the magnetoresistance oscillation minima for the composite fermion theory of Halperin, Lee, and Read (HLR) and its particle-hole conjugate agree exactly. Within the current experimental resolution, the locations of the oscillation minima produced by the Dirac composite fermion coincide with those of HLR. These results may indicate that all three composite fermion theories describe the same long-wavelength physics.

    Particle-hole symmetry in the lowest Landau level of the two-dimensional electron gas requires the electrical Hall conductivity to equal $\\pm e^2/2h$ at half-filling. We study the consequences of weakly broken particle-hole symmetry for magnetoresistance oscillations about half-filling in the presence of an applied periodic one-dimensional electrostatic potential. At fixed electron density, the oscillation minima are asymmetrically biased towards higher magnetic fields, while at fixed magnetic field, the oscillations occur symmetrically as the electron density is varied about half-filling. We find an approximate "sum rule" obeyed for all pairs of oscillation minima that can be tested in experiment. We discuss the implications of our results and approximations for the description of the half-filled Landau level.

    The mechanical action on iron of the first horseshoe electro-magnets (1824) was obvious. They quickly found important applications (telegraphy). Their use to investigate more subtle magnetic, magneto-optical, atomic or nuclear properties of matter began in 1845 with Faraday. Until the 1970s, when superconducting magnets became common, iron-cored electromagnets were normally used to produce steady magnetic fields of high intensity.

    Objectives To investigate associations between the personality factors and survival during 8 years follow-up. Methods Domains of personality and selected facet scores were assessed in 597 Medicare recipients (aged 66 to 102 years) who were followed up for approximately 8 years. Personality domains and factors were assessed using the Revised NEO Personality Inventory (NEO-PI-R). Using proportional hazards regression, the present study builds on a previous analysis of the NEO-PI-R domains and selected facet scores, which revealed that the Neuroticism facet Impulsiveness, Agreeableness facet Straightforwardness, and Conscientiousness facet Self-Discipline were related to longer life during 4 years of follow-up. In the present study, we extended the follow-up period by an additional 4 years, examining all 30 facets, and using accelerated failure time (AFT) modeling as an additional analytic approach. Unlike proportional hazards regression, AFT permits inferences about the median survival length conferred by predictors. Each facet was tested in a model that included health-related covariates and NEO-PI-R factor scores for dimensions that did not include that facet. Results Over the 8-year mortality surveillance period, Impulsiveness was not significant, but Straightforwardness and Self-Discipline remained significant predictors of longevity. When dichotomized, being high versus average or low on Self-Discipline was associated with an approximately 34% increase in median lifespan. Longer mortality surveillance also revealed that each standard deviation of Altruism, Compliance, Tender-Mindedness, and Openness to Fantasy was associated with an estimated 9–11% increase in median survival time. Conclusions After extending the follow-up period from 4 to 8 years, Self-Discipline remained a powerful predictor of survival. Facets associated with imagination, generosity, and higher quality interpersonal interactions become increasingly important when the follow-up period was extended to 8 years. PMID:24933014

We tested a technique to provide rapid automated total spine MRI screening with improved tissue contrast through optimized fat-water separation.Methods: The entire spine was auto-imaged in two contiguous 35 cm field of view (FOV sagittal stations, utilizing out-of-phase fast gradient echo (FGRE and T1 and/or T2 weighted fast spin echo (FSE IDEAL (Iterative Decomposition of Water and Fat with Echo Asymmetric and Least-squares Estimation sequences. 18 subjects were studied, one twice at 3.0T (pre and post contrast and one at both 1.5 T and 3.0T for a total of 20 spine examinations (8 at 1.5 T and 12 at 3.0T. Images were independently evaluated by two neuroradiologists and run through Automated Spine Survey Iterative Scan Technique (ASSIST analysis software for automated vertebral numbering.Results: In all 20 total spine studies, neuroradiologist and computer ASSIST labeling were concordant. In all cases, IDEAL provided uniform fat and water separation throughout the entire 70 cm FOV imaged. Two subjects demonstrated breast metastases and one had a large presumptive schwannoma. 14 subjects demonstrated degenerative disc disease with associated Modic Type I or II changes at one or more levels. FGRE ASSIST afforded subminute submillimeter in-plane resolution of the entire spine with high contrast between discs and vertebrae at both 1.5 and 3.0T. Marrow signal abnormalities could be particularly well characterized with IDEAL derived images and parametric maps.Conclusion: IDEAL ASSIST is a promising MRI technique affording a rapid automated high resolution, high contrast survey of the entire spine with optimized tissue characterization.

    Full Text Available Most species belonging to Namanereis Chamberlin, 1919 live in freshwater and subterranean waters, even in water bodies several meters above sea level. A new species belonging to the stygobiont Namanereis group is described here; it shares the common morphological characters of absence of eyes and pigmentation, bifid jaws, elongation of chaetae and cirri, which have been recently regarded as troglomorphies. Because these features are used in evaluations of phylogenetic affinity in Namanereis, a review of these features was made for all known namanereidins, and it was extended to include species in Namalycastis Hartman, 1959. It is shown that elongation of tentacular and dorsal cirri, or elongation of upper sub-acicular falcigers in pre- or post-acicular fascicles, are not exclusive or restricted to species living in subterranean habitats or to Namanereis, because these features are also present in several Namalycastis species. However, the presence of bifid jaws, and the absence of eyes are exclusively found in namanereidins living in subterranean habitats. A hypothetical evolutionary derivation of bifid jaws is proposed, based upon observations of jaw morphology of several species. These exclusive troglomorphic characters (bifid jaws, eyeless are regarded as convergent features to aphotic environments, and they should be discouraged as indicators of common ancestry. The new species, herein described as Namanereis christopheri sp. n., was collected in a cave 435 m above sea level in Saint Vincent, Caribbean Sea. The species resembles N. cavernicola but it differs because it has shorter tentacular cirri, margin of prostomium entire, rounded neuropodial lobes and broader dorsal cirri throughout body. A key to identify all known Namanereis species is included.

    There is firm evidence that egocentric projection from the individual self to the in-group can account for in-group favoritism (Cadinu & Rothbart, 1996).

  19. The Infant Version of the Laboratory Temperament Assessment Battery (Lab-TAB): Measurement Properties and Implications for Concepts of Temperament

    Science.gov (United States)

    Planalp, Elizabeth M.; Van Hulle, Carol; Gagne, Jeffrey R.; Goldsmith, H. Hill

    2017-01-01

    We describe large-sample research using the Infant Laboratory Temperament Assessment Battery (Lab-TAB; Goldsmith and Rothbart, 1996) in 1,076 infants at 6 and 12 months of age. The Lab-TAB was designed to assess temperament dimensions through a series of episodes that mimic everyday situations. Our goal is to provide guidelines for scoring Lab-TAB episodes to derive temperament composites. We also present a set of analyses examining mean differences and stability of temperament in early infancy, gender differences in infant temperament, as well as a validation of Lab-TAB episodes and composites with parent reported Infant Behavior Questionnaire (IBQ; Rothbart, 1981) scales. In general, laboratory observed temperament was only modestly related to parent reported temperament. However, temperament measures were significantly stable across time and several gender differences that align with previous research emerged. In sum, the Lab-TAB usefully assesses individual differences in infant emotionality. PMID:28596748

Phys. 6, 167 (1965)], extensions that embrace multistate walks and, in particular, the persistent random walk. We generalize these extensions to include fractional random walks and derive the associated master equation, namely, the fractional telegrapher's equation. We dedicate this review to our joint work with George H. Weiss (1930-2017). It saddens us greatly to report the recent death of George Weiss, a scientific giant and at the same time a lovely and humble man.

    Science.gov (United States)

    2017-03-01

    Rothbart's model of temperament, defined as individual differences in reactivity and self-regulation, has a strong heuristic value with applications in a wide variety of children's outcomes. Our objective was to test Rothbart's model applied to children's food behaviours and BMI outcome through behavioural measures. Our hypotheses, according to Rothbart's model, were as follows: (i) self-regulation in eating modulates appetite reactivity; (ii) appetite reactivity increases the risk of excess BMI, whereas self-regulation in eating limits this risk. One hundred and four children aged between 7 and 12 years completed four behavioural tasks to assess scores for two components of appetite reactivity (i.e. appetite arousal and appetite persistence) and two components of self-regulation in eating (i.e. self-regulation in eating without hunger and self-regulation in eating speed). Their heights and weights were measured in order to calculate their BMI-for-age. T-tests and regression analysis were used to verify our hypotheses. None of the scores of self-regulation in eating was directly associated with BMI but we observed a significant impact of self-regulation in eating without hunger on appetite arousal (p-value = 0.04), together with a modest but significant association between appetite persistence and BMI (p-value = 0.02). We can thus conclude that our behavioural measures could be used for the determination of the child's eating temperament. Further studies are needed to investigate how to use these measures to improve the treatment of overweight in children. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The present study examined the relation between self-esteem and temperament in a sample of 646 Mexican-American early adolescents (mean age=10.4). Self-esteem was assessed using child reports on the Self-Description Questionnaire II—Short (SDQII-S; Marsh et al., 2005) and temperament was assessed using child and mother reports on the revised Early Adolescent Temperament Questionnaire (Ellis & Rothbart, 2001).

    2015-06-01

    Full Text Available Este artigo visa mostrar a contribuição que Reinhold oferece para o Idealismo Alemão, período filosófico subsequente a Kant quando, determinado a encontrar o ponto de partida do qual derive os conhecimentos teórico e moral, não hesita em examinar cuidadosamente todas as filosofias que imediatamente surgem após a dele e, muitas vezes, até se rende a elas, considerando-as mais apropriadas que a sua própria para o alcance daquilo que buscava: um primeiro princípio que vincule o que em Kant estava separado. Para tanto, Reinhold parte do método transcendental kantiano, e, assim, tenta também, numa só tacada, escapar daquilo que Jacobi chamou de subjetivismo absoluto, referindo-se ao método kantiano.

    Belkhode, Pramod Namdeorao

    2017-06-01

    Field data based model is proposed to reduce the overhauling time and human energy consumed in liner piston maintenance activity so as to increase the productivity of liner piston maintenance activity. The independent variables affecting the phenomenon such as anthropometric parameters of workers (Eastman Kodak Co. Ltd in Section VIA Appendix-A: Anthropometric Data. Ergonomic Design for People at Work, Van Nostrans Reinhold, New York, 1), workers parameters, specification of liner piston data, specification of tools used in liner piston maintenance activity, specification of solvents, axial clearance of big end bearing and bolt elongation, workstation data (Eastman Kodak Co. Ltd in Work Place Ergonomic Design for People at Work, Van Nostrans Reinhold, New York, 2) and extraneous variables, namely, temperature, humidity at workplace, illumination at workplace and noise at workplace (Eastman Kodak Co. Ltd in Chapter V Environment Ergonomic Design for People at Work, Van Nostrans Reinhold, New York, 3) are taken into account. The model is formulated for dependent variables of liner piston maintenance activity to minimize the overhauling time and human energy consumption so as to improve the productivity of liner piston maintenance activity. The developed model can predict the performance of liner piston maintenance activity which involves man and machine system (Schenck in Theories of Engineering Experimentation, Mc-Graw Hill, New York 4). The model is then optimized by optimization technique and the sensitivity analysis of the model has also been estimated.

    The accelerating frequency of the 600 MeV Synchro-Cyclotron (SC) was modulated by the varying capacity of a rotating condenser ("Rotco", the most delicate component of the SC). A 1/5-scale model, dating from the design-period of the SC, was used to study improvements to the SC RF-system, and also the acceleration of ions, first Helium and, at the time of this picture, Carbon. In the middle of the picture is the case containing the Dees. To the left, at the wide end of the cone, a rotco. Reinhold Hohbach is busy with measurements.

    Full Text Available In this book Reinhold SACKMANN reviews the theoretical standing of life-course research and biographical analysis. The book offers differing perspectives on this research and analysis that are at an appropriate level for advanced students. Given the immense development in methods used to study the life course and analyses of biography SACKMANN attempts to present a broad spectrum of biographical themes: age, education, work, family, romantic relationships, health issues, and finances. However, SACKMANN falls short in discussing biographical methods. Instead of discussing methods SACKMANN offers a detailed survey of a number of perspectives regarding individual human affairs.

    Full Text Available This essay examines the convergence of the Protestant left and traditionalist right during the 1950s. Reinhold Niebuhr and the World Council of Churches challenged Cold War liberalism from within. As they did, they anticipated and even applauded the anti-liberalism of early Cold War conservatives. While exploring intellectual precursors of the New Left, this essay forefronts one forgotten byproduct of the political realignments following World War II: The transgressive politics of “conservative socialism.” Furthermore, this work contributes to growing awareness of ecumenical Christian impact within American life.

  13. How shall we speak of children's personalities in middle childhood? A preliminary taxonomy.

    Science.gov (United States)

    Shiner, R L

    1998-11-01

    Developmental researchers have neglected the study of personality traits in middle childhood, thus leaving unanswered many questions about childhood personality structure. This article presents a developmental framework for understanding personality in middle childhood and critically reviews 5 models of temperament and personality structure in this age range: the models of A. Thomas and S. Chess, A. H. Buss and R. Plomin, M. K. Rothbart, J. Block and J. H. Block, and the Big Five. A number of robust personality dimensions common to these models and the broader developmental and adult personality literatures are then discussed: sociability, social inhibition, dominance, negative emotionality, aggressiveness, prosocial disposition, persistence/attention, mastery motivation, inhibitory control, and activity level. These dimensions represent a preliminary taxonomy of personality traits for exploring questions of individual development in childhood.

    Full Text Available O temperamento é uma variável da pessoa que interage com variáveis ambientais e pode assim influenciar as trajetórias de desenvolvimento da criança. O presente estudo teve por objetivo revisar de forma sistemática estudos empíricos, publicados de 2001 a 2006, sobre o tema temperamento e sua relação com o desenvolvimento da criança. Foram selecionados 50 estudos empíricos indexados nas bases de dados PsycINFO, MEDLINE e LILACS por meio de levantamento bibliográfico sistematizado.Verificou-se que a abordagem teórico-conceitual mais adotada pelos estudos foi a abordagem psicobiológica de Rothbart. O temperamento foi avaliado predominantemente por meio de questionários respondidos pelas mães. Os resultados dos estudos indicaram que crianças com o temperamento caracterizado por alto nível de humor negativo, medo, timidez e raiva encontram-se, do ponto de vista do desenvolvimento, suscetíveis de apresentar problemas de desenvolvimento. O temperamento com alto nível de controle com esforço, que indica a capacidade de superar tendências comportamentais e motivacionais dirigidas pelo afeto e reprogramar seu comportamento em situações de conflito de interesses associa-se a resultados desenvolvimentais positivos.El temperamento es una variable de carácter personal que interactúa con las variables ambientales y por lo tanto puede tener una influencia en el desarrollo infantil. El objetivo de este estudio fue revisar de forma sistemática los estudios empíricos publicados desde 2001 hasta 2006 sobre el temperamento y su relación con el desarrollo del niño. Cincuenta estudios empíricos indexados en las bases de datos PsycINFO, MEDLINE y LILACS se seleccionaron mediante una revisión bibliográfica sistemática.

    Poor motor skills and differences in sensory processing have been noted as behavioral markers of common neurodevelopmental disorders. A total of 171 healthy children (81 girls, 90 boys) were investigated at age 3 to examine relations between temperament, sensory processing, and motor coordination. Using the Japanese versions of the Children's Behavior Questionnaire (CBQ), the Sensory Profile (SP-J), and the Little Developmental Coordination Disorder Questionnaire (LDCDQ), this study examines an expanded model based on Rothbart's three-factor temperamental theory (surgency, negative affect, effortful control) through covariance structure analysis. The results indicate that effortful control affects both sensory processing and motor coordination. The subscale of the LDCDQ, control during movement, is also influenced by surgency, while temperamental negative affect and surgency each have an effect on subscales of the SP-J.

    2009-01-01

    Full Text Available International research has increasingly considered temperament as a relevant personal variable in child developmental pathways. The purpose of the present study was to describe the methodology for translation to Portuguese (Brazil of three child temperament assessment instruments based on Rothbart´s theoretical approach. An original translation was modified, based on feedback by two professional translators, three bilingual psychologists, and a sample of 15 Brazilian mothers. A backtranslation by a professional translator was then assessed by the authors of the original (English language instruments. For the final version of the measure, authors of the original instrument judged that 100% of items were consistent with the original items, and a second sample of 15 Brazilian mothers identified no problems with the Portuguese items.

  18. Coupled Thermo-Mechanical and Photo-Chemical Degradation Mechanisms that determine the Reliability and Operational Lifetimes for CPV Technologies

    Dauskardt, Reinhold H. [Stanford Univ., CA (United States)

    2017-04-30

    This project sought to identify and characterize the coupled intrinsic photo-chemo-mechanical degradation mechanisms that determine the reliability and operational lifetimes for CPV technologies. Over a three year period, we have completed a highly successful program which has developed quantitative metrologies and detailed physics-based degradation models, providing new insight into the fundamental reliability physics necessary for improving materials, creating accelerated testing protocols, and producing more accurate lifetime predictions. The tasks for the program were separated into two focus areas shown in the figure below. Focus Area 1, led by Reinhold Dauskardt and Warren Cai with a primary collaboration with David Miller of NREL, studied the degradation mechanisms present in encapsulant materials. Focus Area 2, led by Reinhold Dauskardt and Ryan Brock with a primary collaboration with James Ermer and Peter Hebert of Spectrolab, studied stress development and degradation within internal CPV device interfaces. Each focus area was productive, leading to several publications, including findings on the degradation of silicone encapsulant under terrestrial UV, a model for photodegradation of silicone encapsulant adhesion, quantification and process tuning of antireflective layers on CPV, and discovery of a thermal cycling degradation mechanism present in metal gridline structures.

    The aim of the current pilot study is to investigate the efficacy of a novel enhanced vitreous imaging (EVI) in primary macular holes (MHs) using a spectral-domain optical coherence tomography (SD-OCT). Thirty-four eyes of 32 consecutive patients with a MH were examined in one time cross-sectional study. The vitreomacular interface was assessed using SD-OCT with conventional and EVI technique. Twenty-three of the 34 eyes did not show a Weiss ring, and in 22 of those, we observed a MH with an open roof or operculum and a detached posterior vitreous cortex with conventional vitreous imaging. Using EVI-OCT, we visualized the reflection of the posterior vitreous with a vitreopapillary attachment. One of the 23 eyes without a Weiss ring had a central round retinal defect without an operculum, and the conventional SD-OCT showed an empty vitreous, suggesting a complete posterior vitreous detachment. However, the EVI-OCT revealed the reflection of the posterior vitreous, and the cortex appeared to still be completely attached. In all the 23 eyes without a Weiss ring, EVI-OCT detected the reflection of the posterior vitreous and vitreopapillary attachment. In all 11 eyes with a Weiss ring (stage 4 hole), EVI-OCT showed an optically empty space in the posterior vitreous cavity without a vitreopapillary attachment. EVI-OCT may be a new reliable method for preoperative evaluations to determine the presence or absence of a complete posterior vitreous detachment in macular diseases with an indistinct Weiss ring.

    The present work looks into the microstructural modification in electron irradiated Bombyx mori P31 silk fibers. The irradiation process was performed in air at room temperature using 8 MeV electron accelerator at different doses: 0, 25, 50 and 100 kGy. Irradiation of polymer is used to cross‐link or degrade the desired component or to fix the polymer morphology. The changes in microstructural parameters in these natural polymer fibers have been computed using wide angle X‐ray scattering (WAXS) data and employing line profile analysis (LPA) using Fourier transform technique of Warren. Exponential, Lognormal and Reinhold functions for the column length distributions have been used for the determination of crystal size, lattice strain and enthalpy parameters.

    Full Text Available Barbara Hauck-Dlimi, Susanne Achenbach, Julian Strobel, Reinhold Eckstein, Robert Zimmermann Department of Transfusion Medicine and Haemostaseology, University Hospital Erlangen, Erlangen, Germany Abstract: Transfusion of blood components, transplantations, and exchange of blood between mother and child during pregnancy or at birth can lead to alloimmunization. Because of its clinical relevance, this review brings into focus alloimmunization against red blood cells, human platelet antigens, human leukocyte antigens, and human neutrophil antigens. In principle, an individual is able to develop antibodies after exposure to a nonautogenous antigen, but these cells actually induce alloimmunization only for a minority of patients. An individual producing alloantibodies after having contact with foreign antigens depends on various factors, such as genetic predisposition, underlying diseases, the patient's immune status, and clinical immune modulation. When alloimmunization has occurred, it could lead to problems for future transfusions or transplantations. Keywords: transfusion, alloimmunization, prevention

    Science.gov (United States)

    Hanson, Mark J

    1999-08-01

    At the heart of any ethics of human enhancement must be some normative assumptions about human nature. The purpose of this essay is to draw on themes from a Protestant theological anthropology to provide a basis for understanding and evaluating the tension between maintaining our humanity and enhancing it. Drawing primarily on the work of theologian Reinhold Niebuhr, I interpret enhancement as proceeding from the anxiety that characterizes human experience at the juncture of freedom and finiteness. Religious and moral dimensions of human sinfulness are considered in relation to cultural values that motivate human enhancement generally. I employ these dimensions in a series of benchmarks to suggest a background of theological, anthropological, and moral considerations against which enhancement is not to be condemmed but rather critically evaluated.

    2017-03-01

    This study examined the direct and indirect pathways from maternal effortful control to 2 aspects of children's self-regulation-executive functioning and behavioral regulation-via maternal emotional support. Two hundred seventy-eight children and their primary caregivers (96% mothers) participated in laboratory visits when children were 4 and 5 years, and teachers reported on children's behavior at kindergarten. At the 4-year assessment, maternal effortful control was measured using the Adult Temperament Questionnaire (Evans & Rothbart, 2007) and maternal emotional support was observed during a semistructured mother-child problem-solving task. At the 5-year assessment, children's executive functioning was measured using laboratory tasks designed to assess updating/working memory, inhibitory control, and cognitive flexibility, whereas behavioral regulation was assessed via teacher-report questionnaires on children's attention control, discipline and persistence, and work habits. Results from structural equation modeling indicated that, after controlling for child gender and minority status, and maternal education, maternal effortful control was indirectly associated with both child executive functioning and behavioral regulation through maternal emotional support. Maternal effortful control had a direct association with children's teacher-reported behavioral regulation but not observed executive functioning. These findings suggest that maternal effortful control may be a key contributing factor to the development of children's self-regulatory competencies through its impact on maternal emotional support.

    Planalp, Elizabeth M.; Braungart-Rieker, Julia M.

    2013-01-01

    The degree to which parent sensitivity and infant temperament distinguish attachment classification was examined. Multilevel modeling was used to assess the effect of parent sensitivity and infant temperament on infant–mother and infant–father attachment. Data were collected from mothers, fathers, and their infants (N = 135) when the infant was 3-, 5-, 7-, 12-, and 14-months old. Temperament was measured using the Infant Behavior Questionnaire-Revised (Gartstein & Rothbart, 2003); parent sensitivity was coded during the Still Face Paradigm (Tronick, Als, Adamson, Wise, & Brazelton, 1978); attachment was coded using the Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978). Results indicate that mothers and fathers were less sensitive with insecure-avoidant infants. Whereas only one difference was found for infant–mother attachment groups and temperament, five significant differences emerged for infant–father attachment groups, with the majority involving insecure-ambivalent attachment. Infants classified as ambivalent with fathers were higher in perceptual sensitivity and cuddliness and these infants also showed a greater increase in low-intensity pleasure over time compared with other infants. Results indicate the importance of both parent sensitivity and infant temperament, though operating in somewhat different ways, in the development of the infant–mother and infant–father attachment relationship.

    Full Text Available The goal of this study was to determine the relationship between temperament, social competence, and behavioral problems in preschool-age children. The study is based on a sample of 66 children, 40 males and 26 females, between 2 and 6 years old (M = 3.92, SD = 1.01, and their mothers. Temperament was assessed using the Children’s Behavior Questionnaire, Short Version (CBQ; Putnam & Rothbart, 2006, which provides data on the dimensions of Surgency, Negative Affect, and Effortful Control. We used the Social Competence and Behavior Evaluation Scale (SCBE-30, LaFreniere & Dumas, 1996 to assess Social Competence as well as problems of Anxiety and Aggressive behavior in children. First, boys showed lower scores in both Negative Affectivity and Effortful Control than girls. The study’s main analysis identified a significant negative association between Surgency and Anxiety. In addition, the three dimensions of temperament were associated with aggression-behavioral problems: Surgency and Negative Affectivity in a positive direction, whereas Effortful Control was associated negatively. Finally, Effortful Control showed a moderate and positive correlation with social competence. These results are consistent with contemporary theoretical and empirical evidence on the topic. However, future studies should consider larger samples to know the scope of temperament and social competence in preschool-age children.

    2017-01-01

    The aim of this study was to develop an adapted version of the Early Adolescent Temperament Questionnaire-Revised (EATQ-R) that would be valid and reliable for assessing temperament and its components in Chileans between 12 and 18 years of age. Originally, Ellis and Rothbart (2001) developed this questionnaire (EATQ-R) to be used in North American adolescents. For the study in Chile, a translation protocol was developed, to maintain the original instrument's cultural and linguistic equivalence in the adapted version. Psychometric properties of the EATQ-R, such as factor structure, internal consistency, and convergent validity, were also assessed. The adaption and validation was carried out in two stages, with two different studies. The first study, which included 612 adolescent students from educational establishments in the cities of Santiago and Concepcion, Chile, developed the Chilean version of the 83-item EATQ-R, which has 13 dimensions, belonging to 4 theoretical factors with adequate internal consistency (Cronbach's alpha = 0.79–0.82). The second study assessed the questionnaire's convergent validity, through its application to 973 adolescent students in Santiago. Results show that the effortful control subscale was significantly inversely related to indicators of adolescent maladjustment, such as substance abuse and behavioral problems. In addition, it was directly associated with indicators of self-concept, including self-esteem and self-efficacy. The opposite pattern was observed when considering negative affect. These findings coincide with current knowledge on the relationship between temperament and adjustment in adolescents. PMID:29326616

    Parent reports of temperament are used to study many important topics in child development, such as whether boys and girls differ in their levels of emotional reactivity and self-regulation. However, questions regarding measurement equivalence in parental reports of temperament are largely unexplored, despite the fact that this issue is critical for drawing the correct conclusions from mean-level comparisons. In the current study, measurement invariance across boys and girls (as targets), and mothers and fathers (as informants), was investigated in the Child Behavior Questionnaire (CBQ; Rothbart et al., 2001) using a sample of children ranging in age from 3 to 7 years (N = 605). Several instances of noninvariance were identified across both girls and boys, and mothers and fathers. An evaluation of effect size indices suggests that the practical impact of this noninvariance ranges from negligible to moderate. All told, this study illustrates the importance of taking a psychometrically informed approach to the use of parent reports of child temperament.

    2017-01-01

    The present study examined the independent contributions and the interaction effects of oppositional defiant problems (ODD), callous unemotional traits (CU) and anxiety symptoms on attentional orienting to emotional faces, in a community sample of preschoolers. Additionally, based on Rothbart's (2007) model of temperament, we analyzed whether fine-grained dimensions of reactivity (fear, anger, discomfort, sadness, activity level, approach, high intensity pleasure, impulsivity) and self-regulation (attentional shifting, attentional focusing, inhibitory control), as well as the higher order temperamental factors of negative affectivity, surgency and effortful control are associated with CU traits and ODD-related problems. Attentional orienting to emotional faces was assessed with pictorial Dot-probe task, while teachers rated CU traits and ODD-related problems. Also, parents reported on ODD-related problems, anxiety and temperament. Results indicated significant interaction effects between ODD-related problems and CU, as well as between CU and anxiety, in predicting attentional orientation patterns for angry, fearful and happy faces. Moreover, temperamental reactivity was positively associated with CU traits and ODD-related problems, whereas temperamental self-regulation was negatively related to CU traits and ODD-related problems. Results of this study have implications for early intervention and prevention approaches targeting preschool oppositional defiant problems.

    Full Text Available The aim of this work was to analyze the gender differences found in a sample of 474 Spanish children aged between 6 and 8 years with respect to peer rejection using a sociometric status technique. Thus, we analyzed how temperament (Effortful Control and parenting practices (Parental support and Discipline were involved in this relation. To measure social rejection we used the nominations method in the classroom context, while for temperament and parenting practices, parents were given a TMCQ (Temperament in Middle Childhood Questionnaire; Simmonds and Rothbart, 2004 and the Spanish version of the PCRI (Parent-Child Relationship Inventory; Gerard, 1994. Using an statistical modeling approach, we tested various mediation/moderation models until the best one with selected variables was found to explain the relation between these variables. The results confirmed gender differences in social rejection, with boys being rejected more than girls. The model that gave the best fit was the one that placed effortful control latent variable mediating the relation between gender and social rejection and parenting practices as a latent explanatory variable of effortful control. In conclusion, differences between girls and boys in social rejection are to a large extent explained by the significantly lower scores for boys in effortful control construct and, in turn, these lowest scores are explained by negative parental practices, with low levels of support and discipline.

    Effortful control has been proposed as a set of neurocognitive competencies that is relevant to self-regulation and educational attainment (Posner & Rothbart, 2007). This study tested the hypothesis that a multiagent report of adolescents’ effortful control (age 17) would be predictive of academic persistence and educational attainment (age 23–25), after controlling for other established predictors (family factors, problem behavior, grade point average, and substance use). Participants were 997 students recruited in 6th grade from 3 urban public middle schools (53% males; 42.4% European American; 29.2% African American). Consistent with the hypothesis, the unique association of effortful control with future educational attainment was comparable in strength to that of parental education and students’ past grade point average, suggesting that effortful control contributes to this outcome above and beyond well-established predictors. Path coefficients were equivalent across gender and ethnicity (European Americans and African Americans). Effortful control appears to be a core feature of the self-regulatory competencies associated with achievement of educational success in early adulthood. These findings suggest that the promotion of self-regulation in general and effortful control in particular may be an important focus not only for resilience to stress and avoidance of problem behavior, but also for growth in academic competence.

    Negative emotionality is considered to be the core of the difficult temperament concept (J. E. Bates, 1989; R. L. Shiner, 1998). In this correlational study, the authors examined whether the relations between children's negative emotionality and problematic behavior (internalizing and externalizing) were partially mediated by parenting style (authoritative and authoritarian) in a community sample of 196 3-year-old children and their mothers. The authors assessed maternal perception of child negative emotionality using the Children's Behavior Questionnaire (M. K. Rothbart, S. A. Ahadi, K. L. Hershey, & P. Fisher, 2001) and assessed problematic child behavior by means of maternal report using the Child Behavior Checklist (T. M. Achenbach, 1992). The results showed that the relations between child negative emotionality and internalizing and externalizing behaviors were partially mediated by mothers' authoritative parenting style. Moreover, when the authors used confirmatory factor analysis to decontaminate possible overlap in item content between measures assessing temperament and problematic behavior, the association between negative emotionality and internalizing behavior was fully mediated by authoritative parenting.

  19. Emotional and attentional predictors of self-regulation in early childhood

    Full Text Available The development of self-regulation in early childhood is related to development of emotional regulation and attention, in particular executive attention (Feldman, 2009; Posner & Rothbart, 1998. As the ability to self-regulate is crucial in life (Casey et al., 2011, it is important to reveal early predictors of self-regulation. The aim of the paper is to present the results of longitudinal studies on the relationships between the functioning of attention, regulation of emotion and later self-regulatory abilities. 310 children were assessed at three time points. At 12 months of age emotional regulation in situation of frustration and attention regulation were assessed. At 18 and 24 months behavioral-emotional regulation in the Snack Delay Task was measured. Additionally parents assessed executive attention using The Early Childhood Behavior Questionnaire when children were 26 months old. Structural equation modelling revealed two different paths to development of self-regulatory abilities at 18 months: emotional (reactive system and emotionalattentional and only one emotional-attentional path at 24 months. The early ability to focus attention and later executive attention functioning revealed to be important predictors of self-regulatory abilities both at 18 and 24 months of age.

  20. Chilean Adaptation and Validation of the Early Adolescent Temperament Questionnaire-Revised Version

    2017-12-01

    Full Text Available The aim of this study was to develop an adapted version of the Early Adolescent Temperament Questionnaire-Revised (EATQ-R that would be valid and reliable for assessing temperament and its components in Chileans between 12 and 18 years of age. Originally, Ellis and Rothbart (2001 developed this questionnaire (EATQ-R to be used in North American adolescents. For the study in Chile, a translation protocol was developed, to maintain the original instrument's cultural and linguistic equivalence in the adapted version. Psychometric properties of the EATQ-R, such as factor structure, internal consistency, and convergent validity, were also assessed. The adaption and validation was carried out in two stages, with two different studies. The first study, which included 612 adolescent students from educational establishments in the cities of Santiago and Concepcion, Chile, developed the Chilean version of the 83-item EATQ-R, which has 13 dimensions, belonging to 4 theoretical factors with adequate internal consistency (Cronbach's alpha = 0.79–0.82. The second study assessed the questionnaire's convergent validity, through its application to 973 adolescent students in Santiago. Results show that the effortful control subscale was significantly inversely related to indicators of adolescent maladjustment, such as substance abuse and behavioral problems. In addition, it was directly associated with indicators of self-concept, including self-esteem and self-efficacy. The opposite pattern was observed when considering negative affect. These findings coincide with current knowledge on the relationship between temperament and adjustment in adolescents.

    To examine the effect of toothbrushing with different brands of regular (Meridol, Colgate) and whitening toothpaste (Pearl Weiss, Rembrant, Email Diamant) on bacterial adhesion onto enamel surfaces in vitro. Extracted intact human teeth were brushed twice a day, for 3 minutes with the tested toothpaste for a period of 7 days. Sucrose dependent adhesion of Streptococcus mutans to the tested teeth was measured using pre-radioactive labeled bacteria. S. mutans adhered more to enamel surfaces, pre-brushed with the tested toothpastes, than to teeth which were not brushed. Different profiles of bacterial adhesion were recorded. Both Diamant and Rembrant toothpastes increased bacterial affinity toward the enamel surface as compared to the other toothpastes. Meridol and Pearl Weiss demonstrated a similar adhesion effect as the etching control while brushing with Colgate demonstrated the least bacterial adhesion.

    In this work, we determine the effects of temperature on the magnetoplasmon spectrum of an electrically modulated graphene monolayer as well as a two-dimensional electron gas (2DEG). The intra-Landau band magnetoplasmon spectrum within the self-consistent field approach is investigated for both the aforementioned systems. Results obtained not only exhibit Shubnikov-de Haas (SdH) oscillations but also commensurability oscillations (Weiss oscillations). These oscillations are periodic as a function of inverse magnetic field. We find that both the magnetic oscillations, SdH and Weiss, have a greater amplitude and are more robust against temperature in graphene compared to a conventional 2DEG. Furthermore, there is a {pi} phase shift between the magnetoplasmon oscillations in the two systems which can be attributed to Dirac electrons in graphene acquiring a Berry's phase as they traverse a closed path in a magnetic field.

  3. Low-energy spin dynamics and critical hole concentrations in La2 -xSrxCuO4 (0.07 ≤x ≤0.2 ) revealed by 139La and 63Cu nuclear magnetic resonance

    Baek, S.-H.; Erb, A.; Büchner, B.

    2017-09-01

    We report a comprehensive 139La and 63Cu nuclear magnetic resonance study on La2 -xSrxCuO4 (0.07 ≤x ≤0.2 ) single crystals. The 139La spin-lattice relaxation rate 1 -1 139T is drastically influenced by Sr doping x at low temperatures. A detailed field dependence of 1 -1 139 at x =1 /8 suggests that charge ordering induces the critical slowing down of spin fluctuations toward glassy spin order and competes with superconductivity. On the other hand, the 63Cu relaxation rate 1 -1 63T is well described by a Curie-Weiss law at high temperatures, yielding the Curie-Weiss temperature Θ as a function of doping. Θ changes sharply through a critical hole concentration xc˜0.09 . xc appears to correspond to the delocalization limit of doped holes, above which the bulk nature of superconductivity is established.

  4. Solving the inverse Ising problem by mean-field methods in a clustered phase space with many states.

    Decelle, Aurélien; Ricci-Tersenghi, Federico

    2016-07-01

    In this work we explain how to properly use mean-field methods to solve the inverse Ising problem when the phase space is clustered, that is, many states are present. The clustering of the phase space can occur for many reasons, e.g., when a system undergoes a phase transition, but also when data are collected in different regimes (e.g., quiescent and spiking regimes in neural networks). Mean-field methods for the inverse Ising problem are typically used without taking into account the eventual clustered structure of the input configurations and may lead to very poor inference (e.g., in the low-temperature phase of the Curie-Weiss model). In this work we explain how to modify mean-field approaches when the phase space is clustered and we illustrate the effectiveness of our method on different clustered structures (low-temperature phases of Curie-Weiss and Hopfield models).

    Magnetic susceptibility of 11 glass spherules from the Apollo 14 lunar fines have been measured from room temperature to 4 K. Data taken at room temperature, 77 K, and 4.2 K, show that the soft saturation magnetization was temperature independent. In the temperature range 300 to 77 K the temperature-dependent component of the magnetic susceptibility obeys the Curie law. Susceptibility measurements on these same specimens and in addition 14 similar spherules from the Apollo 11 and 12 mission show a Curie-Weiss relation at temperatures less than 77 K with a Weiss temperature of 3-7 degrees in contrast to 2-3 degrees found for tektites and synthetic glasses of tektite composition. A proposed model and a theoretical expression closely predict the variation of the susceptibility of the glass spherules with temperature.

    Full Text Available Recently (Nagel and Weiss, 2005, the class of homogeneous random tessellations that are stable under the operation of iteration (STIT was introduced. In the present paper this model is reviewed and new results for the mean values of essential geometric features of STIT tessellations in two and three dimensions are provided and proved. For the isotropic model, these mean values are compared with those ones of the Poisson-Voronoi and of the Poisson plane tessellations, respectively.

Em 1933, Hitler assume o poder sobre a Alemanha nazista. Pouco tempo depois, Forster entra em contato com um grupo de escritores que viviam em exílio em Paris e passa sigilosamente a eles os seus conhecimentos sobre o caso. O escritor Ernst Weiss, também médico, usa essas informações de Forster para escrever o seu romance A Testemunha Ocular (Der Augenzeuge, que é publicado somente em 1963. O professor Forster comete suicídio em 1933, depois de sofrer uma campanha de denúncias difamantes. Weiss também se suicida em 1940, quando as tropas alemãs invadem Paris. Várias outras pessoas relacionadas ao boletim médico sobre Hitler são assassinadas pela Gestapo.In 1918, in a military reserve hospital located in the small Pomeranian town of Pasewalk, the neuropsychiatrist Prof. Edmund Forster treated Adolf Hitler, an Austrian caporal suffering from a war neurosis (hysterical blindness, using suggestive techniques. Soon after the Hitler’s ascension to the power in the Nazi Germany, in 1933, Dr. Forster met with a group of exiled writers living in Paris and secretly gave them the information about the case. The writer Ernst Weiss, that was also a physician, latter used this information in order to produce his roman "The Eye Witness", which would be published only in 1963. In 1933, Prof. Forster committed suicide in strange circunstances after successive defamatory statements against him. Also Weiss committed suicide in 1940, when German troops invaded Paris.

    Winkler, E L; Tovar, M; Causa, M T

    2013-07-24

    We have studied the magnetic behaviour of half-doped manganite Y0.5Ca0.5MnO3 in an extended range of temperatures by means of magnetic susceptibility, χ(T), and electron spin resonance (ESR) experiments. At high temperature the system crystallizes in an orthorhombic structure. The resistivity value, ρ ≃ 0.05 Ω cm at 500 K, indicates a metallic behaviour, while the Curie-Weiss dependence of χ(T) and the thermal evolution of the ESR parameters are very well described by a model that considers a system conformed by localized Mn(4+) cores, [Formula: see text], and itinerant, eg, electrons. The strong coupling between t2g and eg electrons results in an enhanced Curie constant and an FM Curie-Weiss temperature that overcomes the AFM interactions between the [Formula: see text] cores. A transition to a more distorted phase is observed at T ≈ 500 K and signatures of localization of the eg electrons appear in the χ(T) behaviour below 300 K. A new Curie-Weiss regime is observed, where the Curie-constant value is consistent with dimer formation. Based on mean-field calculations, the dimer formation is predicted as a function of the interaction strength between the t2g and eg electrons.

    Neutron powder diffraction indicates that CeTiNO{sub 2} and PrTiNO{sub 2} crystallize with orthorhombic Pnma symmetry (Ce: a=5.5580(5), b=7.8369(7), and c=5.5830(4) Å; Pr: a=5.5468(5), b=7.8142(5), and c=5.5514(5) Å) as a result of a{sup –}b{sup +}a{sup –} tilting of the titanium-centered octahedra. Careful examination of the NPD data, confirms the absence of long range anion order in both compounds, while apparent superstructure reflections seen in electron diffraction patterns provide evidence for short range anion order. Inverse magnetic susceptibility plots reveal that the RTiNO{sub 2} (R=Ce, Pr, Nd) compounds are paramagnetic with Weiss constants that vary from −28 to −42 K. Effective magnetic moments for RTiNO{sub 2} (R=Ce, Pr, Nd) are 2.43 μ{sub B}, 3.63 μ{sub B}, and 3.47 μ{sub B}, respectively, in line with values expected for free rare-earth ions. Deviations from Curie–Weiss behavior that occur below 150 K for CeTiNO{sub 2} and below 30 K for NdTiNO{sub 2} are driven by magnetic anisotropy, spin–orbit coupling, and crystal field effects. - Graphical abstract: The structure and magnetism of the oxide nitride perovskites RTiNO{sub 2} (R=Ce, Pr, Nd) have been explored. The average symmetry is shown to be Pnma with a random distribution of oxide and nitride ions and a{sup −}b{sup +}a{sup −} tilting of the titanium-centered octahedra, but electron diffraction shows evidence for short range anion order. All three compounds are paramagnetic but deviations from the Curie Weiss law are seen below 150 K for R=Ce and below 30 K for R=Nd. - Highlights: • The oxide nitride perovskites RTiNO{sub 2} (R=Ce, Pr) have been prepared and their structures determined. • Diffraction measurements indicate short range cis-order of O and N, but no long range order. • Compounds are paramagnetic with Weiss constants that vary from −28 to −42 K. • CeTiO{sub 2}N and NdTiO{sub 2}N deviate from Curie–Weiss behavior below 150 and 30 K, respectively.

  16. Infant Joint Attention, Neural Networks and Social Cognition

    Science.gov (United States)

    Mundy, Peter; Jarrold, William

    2010-01-01

    Neural network models of attention can provide a unifying approach to the study of human cognitive and emotional development (Posner & Rothbart, 2007). This paper we argue that a neural networks approach to the infant development of joint attention can inform our understanding of the nature of human social learning, symbolic thought process and social cognition. At its most basic, joint attention involves the capacity to coordinate one’s own visual attention with that of another person. We propose that joint attention development involves increments in the capacity to engage in simultaneous or parallel processing of information about one’s own attention and the attention of other people. Infant practice with joint attention is both a consequence and organizer of the development of a distributed and integrated brain network involving frontal and parietal cortical systems. This executive distributed network first serves to regulate the capacity of infants to respond to and direct the overt behavior of other people in order to share experience with others through the social coordination of visual attention. In this paper we describe this parallel and distributed neural network model of joint attention development and discuss two hypotheses that stem from this model. One is that activation of this distributed network during coordinated attention enhances to depth of information processing and encoding beginning in the first year of life. We also propose that with development joint attention becomes internalized as the capacity to socially coordinate mental attention to internal representations. As this occurs the executive joint attention network makes vital contributions to the development of human symbolic thinking and social cognition. PMID:20884172

  17. Adaptation of the Infant Behavior Questionnaire-Revised for use in Ethiopia: Expanding cross-cultural investigation of temperament development.

    Gartstein, Maria A; Bogale, Wolayte; Meehan, Courtney L

    2016-11-01

    Cross-cultural differences in temperament were evaluated for Ethiopian (N=109) and U.S. (N=109) samples of infants. We anticipated that the Sidama version of the Infant Behavior Questionnaire-Revised (IBQ-R; Gartstein & Rothbart, 2003) developed for use in Ethiopia would demonstrate satisfactory psychometric properties, and hypothesized significant cross-cultural differences in levels of fine-grained temperament characteristics. Interactions between culture, infant age, and sex were also considered. Internal consistency was satisfactory for 13 of the 14 IBQ-R scales (with a somewhat low estimate observed for Duration of Orienting), and an examination of the structure indicated patterns similar to those observed in the US, and elsewhere. Differences between Ethiopia and the US were noted for Activity Level, Distress to Limitations, Fear, Smiling/Laughter, Falling Reactivity, Cuddliness/Affiliation, Sadness, Approach, and Vocal Reactivity. Parents of infants in the US reported higher levels of attributes associated with Surgency/Positive Affectivity (Activity, Smiling/Laughter, Approach Vocal Reactivity), whereas Ethiopian infants' scores were higher for Distress to Limitations and Fear, linked with the over-arching temperament factor of Negative Emotionality; however, US infants received higher ratings on Sadness, also associated with this factor. Higher Falling Reactivity, a regulation-related attribute, was reported for Ethiopian infants, with US babies receiving higher Cuddliness/Affiliation scores. Significant culture*age interactions were observed for Activity and Fear, along with a significant culture*age*sex interaction for Distress to Limitations. Copyright © 2016 Elsevier Inc.

    2015-12-01

    Full Text Available This article provides information to support the database article titled “UbSRD: The Ubiquitin Structural Relational Database” (Harrison et al., 2015 [1] . The ubiquitin-like homology fold (UBL represents a large family that encompasses both post-translational modifications, like ubiquitin (UBQ and SUMO, and functional domains on many biologically important proteins like Parkin, UHRF1 (ubiquitin-like with PDB and RING finger domains-1, and Usp7 (ubiquitin-specific protease-7 (Zhang et al., 2015; Rothbart et al., 2013; Burroughs et al., 2012; Wauer et al., 2015 [2–5]. The UBL domain can participate in several unique protein–protein interactions (PPI since protein adducts can be attached to and removed from amino groups of lysine side chains and the N-terminus of proteins. Given the biological significance of UBL domains, many have been characterized with high-resolution techniques, and for UBQ and SUMO, many protein complexes have been characterized. We identified all the UBL domains in the PDB and created a relational database called UbSRD (Ubiquitin Structural Relational Database by using structural analysis tools in the Rosetta (Leaver et al., 2013; O’Meara et al., 2015; Leaver-fay et al., 2011 [1,6–8]. Querying UbSRD permitted us to report many quantitative properties of UBQ and SUMO recognition at different types interfaces (noncovalent: NC, conjugated: CJ, and deubiquitanse: DB. In this data article, we report the average number of non-UBL neighbors, secondary structure of interacting motifs, and the type of inter-molecular hydrogen bonds for each residue of UBQ and SUMO. Additionally, we used PROMALS3D to generate a multiple sequence alignment used to construct a phylogram for the entire set of UBLs (Pei and Grishin, 2014 [9]. The data described here will be generally useful to scientists studying the molecular basis for recognition of UBQ or SUMO.

  19. Perceptual Sensitivity and Response to Strong Stimuli Are Related

    Directory of Open Access Journals (Sweden)

    Anna C. Bolders

    2017-09-01

    Full Text Available To shed new light on the long-standing debate about the (independence of sensitivity to weak stimuli and overreactivity to strong stimuli, we examined the relation between these tendencies within the neurobehavioral framework of the Predictive and Reactive Control Systems (PARCS theory (Tops et al., 2010, 2014. Whereas previous studies only considered overreactivity in terms of the individual tendency to experience unpleasant affect (punishment reactivity resulting from strong sensory stimulation, we also took the individual tendency to experience pleasant affect (reward reactivity resulting from strong sensory stimulation into account. According to PARCS theory, these temperamental tendencies overlap in terms of high reactivity toward stimulation, but oppose each other in terms of the response orientation (approach or avoid. PARCS theory predicts that both types of reactivity to strong stimuli relate to sensitivity to weak stimuli, but that these relationships are suppressed due to the opposing relationship between reward and punishment reactivity. We measured punishment and reward reactivity to strong stimuli and sensitivity to weak stimuli using scales from the Adult Temperament Questionnaire (Evans and Rothbart, 2007. Sensitivity was also measured more objectively using the masked auditory threshold. We found that sensitivity to weak stimuli (both self-reported and objectively assessed was positively associated with self-reported punishment and reward reactivity to strong stimuli, but only when these reactivity measures were controlled for each other, implicating a mutual suppression effect. These results are in line with PARCS theory and suggest that sensitivity to weak stimuli and overreactivity are dependent, but this dependency is likely to be obscured if punishment and reward reactivity are not both taken into account.

  20. The determination of residence times in a pilot plant

    Ramírez, F. Pablo; Cortés, M. Eugenia

    2004-01-01

    It is well known that residence time distributions (RTD) are very important in many chemical processes such as separation, reforming, hydrocracking, fluid catalytic cracking, hydrodesulfuration, hydrogenation among others [3 Procédés de transformation, Editions Technip, Institute Francais du Petrole, Paris, France, 1998]. In addition, tracers can be used to measure the velocity, distribution and residence time of any stream through any part of an industrial [Guidebook on Radioisotope Tracers in Industry, IAEA, Vienna, 1990] or experimental system. Perhaps the best quality of radiotracers is that they do not interfere with normal unit operations or production scheduling. In this paper are presented the RTDs obtained in a pilot plant for a hydrogenation process [IMP, Technical Report, Determinación del tiempo de residencia promedio en el reactor de la planta piloto de hidroagotamiento de crudo, 2002]. The RTDs show a random phenomenon, which is not typical of this type of chemical processes. Several RTDs were determined in order to confirm this random behavior. The data were obtained using as a tracer a radioactive form of sodium iodide containing iodine-131 [The Condensed Chemical Dictionary, 10th Ed., Van Nostrand Reinhold, USA, 1981]. The process works with two phases in a countercurrent flow, inside a packed column. The liquid phase goes down by gravity. The gas phase goes up due to pressure difference [3 Procédés de transformation, Editions Technip, Institute Francais du Petrole, Paris, France, 1998]. The tracer was selected such that it would follow the liquid phase.

    Artero, Ana; Martinez-Ibañez, Juncal; Civera, Miguel; Martínez-Valls, José Francisco; Ortega-Serrano, Joaquín; Real, José Tomás; Ascaso, Juan Francisco

    Roux-en-Y gastric bypass (RYGB) is an effective treatment for weight loss in patients with morbid obesity. However, few studies have assessed its long-term efficacy in super-obese patients. The study objective was to analyse the long-term effectiveness of RYGB and its effect on improvement of comorbidities after 10 years of follow-up, and to compare the results depending on baseline BMI (<50kg/m(2) vs ≥50kg/m(2)). A retrospective study was conducted in 63 patients referred for RYGB with a 10-year or longer follow-up period. Mean BMI before surgery was 55kg/m(2). Mean BMI decreased to 38.1kg/m(2) at 10 years of follow-up. The success rates according to Reinhold criteria modified by Christou and to Biron's criteria were 30.2% and 54% respectively. The corresponding rates in super-obese patients were 21.4% and 57.1%. Significant, stable improvement was seen in diabetes, dyslipidemia, hypertension, and sleep apnea. Sustained weight loss was achieved after gastric bypass, with a mean excess weight loss of 50.6% after 10 years despite the high prevalence of super-obesity. Comorbidity improvement was maintained.

    Motivated by earlier theoretical studies which utilized simplified models and by a very recent experiment regarding antiproton-impact of hydrogen, we present a description (D.R. Schultz, P.S. Krstić, C.O. Reinhold, and J.C. Wells, Phys. Rev. Lett. (1996) submitted.) of ionization of hydrogen and hydrogenic ions based on very large scale numerical solutions of the time-dependent Schrödinger equation in three spatial dimensions and on analysis of the topology of the electronic eigenenergy surfaces in the plane of complex internuclear distance. It is illustrated how ionization of atomic hydrogen and hydrogenic ions by antiprotons is quite different from that for impact by positively charged particles at low energies. Most significantly, for hydrogen targets, the quasi-molecular electronic eigenenergies approach close to and ultimately merge with the continuum at small distances, leading to a plateau of the low energy ionization cross section.

    In comparison with the lateral (Wallenberg), medial (Dejerine) and hemimedullary (Reinhold) medulla oblongata syndromes, the Babinski-Nageotte and Cestan-Chenais syndromes are much less familiar cerebrovascular disorders. While the Babinski-Nageotte syndrome is usually confused with the hemimedullary syndrome, reports of the extremely rare Cestan-Chenais syndrome are missing from the modern neurological literature. The pathological and magnetic resonance imaging (MRI) correlations of the Cestan-Chenais syndrome have not been shown so far. We compared clinical and MRI features of two patients exhibiting classical Babinski-Nageotte and Cestan-Chenais syndromes according to their original descriptions with those of three patients with lateral, medial and hemimedullary syndromes. Our study shows that Babinski-Nageotte syndrome includes all symptoms of the Wallenberg syndrome and additionally contralateral hemiparesis due to a spreading of the "Wallenbergian" lateral lesion to the pyramidal tract. The Cestan-Chenais syndrome includes all symptoms of the Babinski-Nageotte syndrome with the exception of the ipsilateral cerebellary hemiataxia because of sparing of the posterior spinocerebellar tract. The Babinski-Nageotte syndrome is neither clinically nor on MRI identical with hemimedullary syndrome. Hypoglossal palsy, an invariable symptom of hemimedullary lesion is not part of the Babinski-Nageotte syndrome. The contralateral hypesthesia is dissociated in the Babinski-Nageotte syndrome. The Babinski-Nageotte and Cestan-Chenais syndromes are intermediolateral medullary syndromes with all (Babinski-Nageotte) or nearly all (Cestan-Chenais) features of the lateral and some features of the medial medulla oblongata syndromes.

    when spots are visible on its surface. The presence of spots together with the stellar rotation leads to a periodic modulation on the light curve. By studying that modulation one can then learn about the stellar rotation and also magnetic activity. Recently, Reinhold & Arlt [1] proposed a method based on the analysis of the Lomb Scargle periodogram of the light curve to identify the sign of the differential rotation, i.e. whether the equator rotates faster than the poles or the opposite. We have been studying in detail the spots' impact on the light curve and on the resulting periodogram. We find that, under some conditions, the periodogram can actually provide an estimate of the true spot latitudes and/or the stellar inclination angle. Moreover, we find that the impact of the spot on the ratio between the heights of the second and first harmonics of the main peaks in the periodogram can be described by a single parameter, the visibility time of the spot. Finally, we also identify possible sources of false positives/negatives for the sign of the differential rotation.

  6. The City of Man, European Émigrés, and the Genesis of Postwar Conservative Thought

    2012-08-01

    Full Text Available This article explores the forgotten manifesto The City of Man: A Declaration on World Democracy, which was composed in 1940 by a group of prominent American and European anti-isolationist intellectuals, including Thomas Mann, Reinhold Niebuhr, and Hermann Broch. Written in response to the victories of Nazi Germany, the manifesto declared that the United States had a new global responsibility not only to lead the war against fascism and Marxism, but also to establish a global order of peace and democracy under U.S. hegemony. Moreover, the authors of the manifesto claimed that such an order would have to be based on the rejuvenation of conservative values; in their view, the collapse of Western democracies under the weight of totalitarian aggression was the consequence of inner moral and intellectual degeneration. The City of Man therefore called on the United States to lead the spiritual transformation of democracy into a modern political religion, which would bring about the intellectual and political unity of humanity under one state and one creed. This article analyzes the manifesto as a rare window into the difficulty intellectuals faced as they tried to conceptualize the totalitarian challenge prior to the United States’ entry into the war. Moreover, it claims that The City of Man expressed the emergence of postwar conservatism and Cold War ideology, as well as the unique role played by European émigrés in this process.

    Hole and electron doped LaCoO3 is studied using dynamical mean-field theory. The one-particle spectra are analyzed and compared to the available experimental data, in particular the x-ray absorption spectra. Analyzing the temporal spin-spin correlation functions we find the atomic intermediate spin state is not important for the observed Curie-Weiss susceptibility. Contrary to the commonly held view about the roles played by the t2g and eg electrons we find narrow quasiparticle bands of t2g character crossing the Fermi level accompanied by strongly damped eg excitations.

    Full Text Available Abstract Applications of Genome Polymorphism Scans range from the relatively simple such as gender determination and confirmation of biological relationships, to the relatively complex such as determination of autozygosity and propagation of genetic information throughout pedigrees. Unlike nearly all other clinical DNA tests, the Scan is a universal test – it covers all people and all genes. In balance, I argue that the Genome Polymorphism Scan is the most powerful, affordable clinical DNA test available today.

    2005-01-01

    Eponyms in medicine are frequently criticized because they may not represent the person who first described a syndrome or disease. Although eponyms are very commonly used, most readers are probably unaware of who it was that named the diseases and whether the original description of the disease still corresponds to the modern definition. The 10 most common eponyms in esophageal diseases were revisited. The men and the disease behind Barrett's esophagus, Boerhaave's syndrome, Mallory-Weiss syndrome, Cameron ulcer, Schatzki ring, Paterson-Kelly syndrome, Plummer-Vinson, Chagas's disease, Zenker diverticulum and Killian diverticulum are reviewed here.

  19. Curie law, entropy excess, and superconductivity in heavy fermion metals and other strongly interacting fermi liquids.

    2005-12-02

    Low-temperature thermodynamic properties of strongly interacting Fermi liquids with a fermion condensate are investigated. We demonstrate that the spin susceptibility of these systems exhibits the Curie-Weiss law, and the entropy contains a temperature-independent term. The excessive entropy is released at the superconducting transition, enhancing the specific heat jump deltaC and rendering it proportional to the effective Curie constant. The theoretical results are favorably compared with the experimental data on the heavy-fermion metal CeCoIn5, as well as 3He films.

    In 2017 the scientific community celebrates 100 years since Weiss and Piccard made the first observation of a caloric effect in magnetic materials, when studying temperature changes in Nickel subjected to applied magnetic fields near the Curie transition temperature [1]. The effect was called the magneto-caloric effect. A thermodynamic formulation of the adiabatic magneto-caloric refrigeration was given independently by Debye [2] and Giauque [3] in 1920s, followed by the first experimental confirmation of adiabatic refrigeration in 1933 [4]. Since then, the research field has expanded considerably and other interesting caloric effects have been discovered in materials displaying different forms of ferroic order.

With a reduction of the volume, the DLM amplitude decreases gradually. In the temperature dependence of electrical resistivity ρ under hydrostatic pressure, an upturn in the variation of ρ in the paramagnetic state was observed with decreasing temperature, which is originated from the Curie-Weiss-type DLM fluctuations. In the vicinity of the critical pressure for disappearance of the DLM, the variation of ρ as a function of log(T was observed.

Logo após a ascensão de Hitler ao poder na Alemanha nazista, em 1933, o Prof. Forster reuniu-se com um grupo de escritores alemães exilados em Paris e secretamente passou a eles informações sobre o caso. O escritor Ernst Weiss, também médico, mais tarde utilizou tais informações para escrever seu romance A Testemunha Ocular, que, porém, só seria publicado em 1963. Em circunstâncias estranhas, o Prof. Forster cometeu suicídio após uma campanha difamatória sistemática articulada pelos nazistas em 1933.

    Coupling an antisymmetric tensor field to the electromagnetic field in a dyonic Reissner-Nordström-anti-de Sitter black hole background, we build a holographic model for the paramagnetism/ferromagnetism phase transition. In the case of zero magnetic field, the time reversal symmetry is broken spontaneously and spontaneous magnetization happens at low temperatures. The critical exponents are in agreement with the ones from mean field theory. In the case of nonzero magnetic field, the model realizes the hysteresis loop of a single magnetic domain and the magnetic susceptibility satisfies the Curie-Weiss law.

  19. Magnetic nanoparticles: reactive oxygen species generation and potential therapeutic applications

    Science.gov (United States)

    Mai, Trang; Hilt, J. Zach

    2017-07-01

    Magnetic nanoparticles have been demonstrated to produce reactive oxygen species (ROS), which play a major role in various cellular pathways, via Fenton and Haber-Weiss reaction. ROS act as a double-edged sword inside the body. At normal conditions, the generation of ROS is in balance with their elimination by scavenger systems, and they can promote cell proliferation as well as differentiation. However, at an increased level, they can cause damages to protein, lead to cellular apoptosis, and contribute to many diseases including cancer. Many recent studies proposed a variety of strategies to either suppress toxicity of ROS generation or exploit the elevated ROS levels for cancer therapy.

    Nanocrystalline, granular samples of La{sub 0.7}Ca{sub 0.3}MnO{sub 3} (LCMO) were synthesized by reactive milling method and annealed at various temperatures. Effect of grain size on the low-field magnetoresistance (LFMR) has been investigated. Based upon a phenomenological model taking into account the spin-polarized transport across grain boundaries, we explained magnetic field dependence of magnetoresistance in LCMO samples. The contribution to the magnetoresistance coming from spin-polarized tunneling was separated out from the intergranular contribution. The fitted results showed that the temperature dependence of the LFMR displays a Curie-Weiss law-like behavior.

    Full Text Available Dielectric behavior and diffuse phase transition have been investigated in Sb doped lead lanthanum zirconate titanate (PLZT ceramics to understand the role of La and Sb in ferroelectric-to-relaxor crossover. Rayleigh and Curie–Weiss type law fittings show that the La substitution gradually transforms the PLZTs from ferroelectric to relaxor, while Sb dopants weaken the diffuseness and dielectric dispersion. Vogel–Fulcher model reveals that the samples at high La concentration are fully in relaxor state comparable to the undoped PLZTs.

    Morris Cohen is mainly remembered as a philosopher of history and law, a friend of jurists (Oliver Wendell Holmes, Felix Frankfurter), and a teacher of more prominent philosophers (e.g., Ernest Nagel, Paul Weiss, Morton White). But his unique position as a student of the work of Russell and Peirce led him to make a distinctive contribution to the debate over realism in in the 1910s. Largely ignored and completely uncited, his early papers formulated what would later be called "objective relativism," influencing the later work of Columbia naturalism, hence American philosophy, from the 1940s to the 1960s.

    An r-Spin Riemann surface is a Riemann surface equipped with a choice of rth root of the (co)tangent bundle. We give a careful construction of the moduli space (orbifold) of r-Spin Riemann surfaces, and explain how to establish a Madsen–Weiss theorem for it. This allows us to prove the “Mumford...... conjecture” for these moduli spaces, but more interestingly allows us to compute their algebraic Picard groups (for g≥10, or g≥9 in the 2-Spin case). We give a complete description of these Picard groups, in terms of explicitly constructed line bundles....

    Full Text Available Spindle cell hemangioendothelioma (SCH was originally described by Weiss and Enzinger (1986 as a low-grade angiosarcoma resembling both cavernous hemangioma and Kaposi's sarcoma. Recent studies suggest that SCH is a benign neoplasm or reactive lesion accompanying a congenital or acquired vascular malformation. Most SCHs present as one or more nodules affecting the dermis or subcutis of the distal extremities. Few reports describe SCH of the head and neck region; even fewer note intramuscular SCH. Here, we describe a case of SCH involving the temporal muscle mimicking soft tissue sarcoma, who had a successful surgical treatment with a coronal approach and zygomatic osteotomy.

    From the discovery of the first known human homeobox mutation in MSX2 for craniosynostosis of the Boston type by Jams to the recent report of 2 mutations in FGFR2 in Apert syndrome by Wilkie, it is clear that the molecular aspects of syndromes with craniosynostosis are becoming known at a dizzying pace. Four of the syndromes involve mutations in FGFR2. The first to emerge was Crouzon syndrome followed by Jackson-Weiss syndrome, Pfeiffer syndrome, and finally Apert syndrome. Earlier, Muenke showed that Pfeiffer syndrome was heterogeneous, some families having a mutation in FGFR1. 50 refs., 4 tabs.

    A temperature dependence of the magnetic susceptibility [χ(T)] of rare-earth borates RAl3(BO3)4 (R = Tb, Er, or Ho) is measured by the Faraday method at temperatures in the interval 20-850°C. Nonlinear anomalies caused by structural transitions are observed in the dependences χ-1(T). It is established that the dependences χ-1(T) for each phase obey the linear Curie-Weiss law. The Curie temperatures and the magnetic moments corresponding to the chemical formula of the compounds have been found.

  18. Inverse problem for multispecies ferromagneticlike mean-field models in phase space with many states.

    Science.gov (United States)

    Fedele, Micaela; Vernia, Cecilia

    2017-10-01

    In this paper we solve the inverse problem for the Curie-Weiss model and its multispecies version when multiple thermodynamic states are present as in the low temperature phase where the phase space is clustered. The inverse problem consists of reconstructing the model parameters starting from configuration data generated according to the distribution of the model. We demonstrate that, without taking into account the presence of many states, the application of the inversion procedure produces very poor inference results. To overcome this problem, we use the clustering algorithm. When the system has two symmetric states of positive and negative magnetizations, the parameter reconstruction can also be obtained with smaller computational effort simply by flipping the sign of the magnetizations from positive to negative (or vice versa). The parameter reconstruction fails when the system undergoes a phase transition: In that case we give the correct inversion formulas for the Curie-Weiss model and we show that they can be used to measure how close the system gets to being critical.

    The effects of Mn substitution on the structure and magnetic properties of the SeMO{sub 3} (M = Cu{sub 1-x}Mn{sub x}) solid solution have been studied. Rietveld refinements of the x-ray diffraction patterns of these samples indicate that the manganese ions occupy copper sites. This replacement induces significant changes in the M-O bond lengths that give rise to abrupt decreases of the [M-O{sub 6}] octahedral distortion. In contrast, the M-O(1)-M and M-O(2)-M bond angles remain essentially constant. The magnetic behaviour of this solid solution was studied in the temperature range of 2 K < T < 300 K. The temperature dependence of the inverse magnetic susceptibility is well described by the Curie-Weiss law at high temperatures, in the composition range studied. We found that the substitution of Mn for Cu induces a sharp drop in the saturation moment of SeCuO{sub 3}. At about 10% of Mn there is a change from positive to negative Weiss constant {theta}{sub W} that is mainly due to the [M-O{sub 6}] octahedral distortion introduced by the substitution of the larger Mn ions in the structure. The M- H isotherms show a weak ferromagnetism at about 52 K in SeMnO{sub 3}.

  20. 3D Spin-Liquid State in an Organic Hyperkagome Lattice of Mott Dimers

    We report the first 3D spin liquid state of isotropic organic spins. Structural analysis, and magnetic and heat-capacity measurements were carried out for a chiral organic radical salt, (TBA) 1.5[(-)-NDI -Δ ] (TBA denotes tetrabutylammonium and NDI denotes naphthalene diimide), in which (-)-NDI -Δ forms a K4 structure due to its triangular molecular structure and an intermolecular π -π overlap between the NDI moieties. This lattice was identical to the hyperkagome lattice of S =1 /2 Mott dimers, and should exhibit 3D spin frustration. In fact, even though the high-temperature magnetic susceptibility followed the Curie-Weiss law with a negative Weiss constant of θ =-15 K , the low-temperature magnetic measurements revealed no long-range magnetic ordering down to 70 mK, and suggested the presence of a spin liquid state with a large residual paramagnetism χ0 of 8.5 ×10-6 emu g-1 at the absolute zero temperature. This was supported by the N 14 NMR measurements down to 0.38 K. Further, the low-temperature heat capacities cp down to 68 mK clearly indicated the presence of cp for the spin liquid state, which can be fitted to the power law of T0.62 in the wide temperature range 0.07-4.5 K.

    2017-09-01

    A high-pressure-synthesized double perovskite Sr2YOsO6 was investigated by synchrotron X-ray diffraction and measurements of its magnetic susceptibility, specific heat capacity, complex impedance, and complex dielectric constant. It crystallized into a monoclinic double perovskite structure (P21/n) with complete ordering of the Y and Os atoms. Its magnetic behaviors, including the antiferromagnetic transition temperature (˜52 K), Curie-Weiss effective moment [3.48(5) μB/Os], and Weiss temperature [-350.1(7) K], were close to the respective values of Sr2YOsO6 previously synthesized without an applied pressure of 6 GPa. Transport property measurements revealed that the lower limit of the activation energy was 192(1) meV and the charge gap remained open regardless of the presence of magnetic order, conflicting with the electron delocalization predicted by theoretical calculations. Further consideration, including theoretical and experimental investigations of the roles of spin-orbit coupling and U of the 5d electrons of Os 5d-t2g3, may assist in understanding the general magnetic and insulating behaviors of quasi-half-filled 5d-t2g3oxides in the perovskite category toward the use of 5d double perovskite for magnetic applications.

Subjects spent the most time watching the eyes and mouth. A significant trend in gaze durations was found with the longest gaze duration on the mouth, followed by the eyes and then the nose. In addition, eye-gaze patterns changed across familiarization as subjects learned the word boundaries, showing decreased attention to the mouth in later blocks while attention on other facial features remained consistent. These findings highlight the importance of the visual component of speech processing and suggest that the mouth may play a critical role in visual speech segmentation.

    This study evaluates the effectiveness of cognitive behavioral therapy (CBT) in improving the home behavior of children with attention deficit hyperactivity disorder (ADHD). Twenty-five boys (age 7 to 13) with a diagnosis of ADHD were randomized to a CBT or supportive therapy control group. Outcome measures included parent and teacher ratings of the child on the Behavior Problem Checklist-Attention Problem Subscale (BPC-AP), and the Self-Control Rating Scale (SCRS), parent ratings on the Modified Werry Weiss Activity Scale, and child ratings on the Piers Harris Self-Concept Scale and Matching Familiar Figures Task. Data were analyzed using a two-way analysis of variance for main effects. A significant improvement favoring CBT was found on the Werry Weiss Scale, which measures the parent's perception of the child's hyperactivity in the home, and the child's rating of his/her self-esteem on the Piers Harris Self-Concept Scale. Other outcome measures did not demonstrate statistical differences. This research provides support for the use of CBT in children with ADHD. CBT was found to improve the parent's perception of the child's hyperactivity in the home as well as the child's self-esteem.

    Reported are the synthesis, crystal structure, electronic structure, and magnetic properties of a series of zinc-rich ternary phases with formulas RE2Zn5Tt (RE = La-Nd; Tt = Sn and Pb). The structures of these compounds have been established by single-crystal and powder X-ray diffraction. They crystallize in the orthorhombic space group Cmcm (No. 63, LaRhSn2 structure type, Pearson symbol oC32). The most prominent structural feature is the trigonal-planar coordination of the Sn(Pb) atoms; the latter interconnect layers of Zn atoms to comprise a complex [Zn5Tt] polyanionic framework. The structural relationships between the structure of the title compounds and the EuIn4, La3Al11, and YIrGe2 structure types are highlighted. Temperature-dependent DC magnetization measurements indicate Pauli-like paramagnetism for La2Zn5Sn, while Ce2Zn5Sn, Pr2Zn5Sn, and Nd2Zn5Sn display Curie-Weiss behavior in the high-temperature regime. At cryogenic temperatures, the magnetic responses of Ce2Zn5Sn, Pr2Zn5Sn, and Nd2Zn5Sn appear to deviate from the Curie-Weiss law; however, no magnetic orderings could be observed down to 5 K. Theoretical considerations of the electronic structure on the basis of the tight-binding linear muffin-tin orbital (TB-LMTO-ASA) method are also presented and discussed.

    Bi3Mn4O12(NO3) (BMNO) is a honeycomb bilayers antiferromagnet, not showing any ordering down to very low temperatures despite having a relatively large Curie-Weiss temperature. Using ab initio density functional theory, we extract an effective spin Hamiltonian for this compound. The proposed spin Hamiltonian consists of antiferrimagnetic Heisenberg terms with coupling constants ranging up to third intralayer and fourth interlayer neighbors. Performing Monte Carlo simulation, we obtain the temperature dependence of magnetic susceptibility and so the Curie-Weiss temperature and find the coupling constants which best match with the experimental value. We discover that depending on the strength of the interlayer exchange couplings, two collinear spin configurations compete with each other in this system. Both states have in plane Néel character, however, at small interlayer coupling spin directions in the two layers are antiparallel (N1 state) and discontinuously transform to parallel (N2 state) by enlarging the interlayer couplings at a first order transition point. Classical Monte Carlo simulation and density matrix renormalization group calculations confirm that exchange couplings obtained for BMNO are in such a way that put this material at the phase boundary of a first order phase transition, where the trading between these two collinear spin states prevents it from setting in a magnetically ordered state.

    The Rapid Publication paper by Cohen on the mutational basis of craniosynostosis is a thorough review of the recent work of our group and of that of others. However, we are concerned that his analysis of the phenotypic variation of Pfeiffer and Jackson-Weiss syndromes obscures important issues that need to be addressed. In the original large Amish family reported by Jackson and Weiss, individuals were variably affected with a craniosynostosis syndrome characterized facially by proptosis, hypertelorism, and midface hypoplasia. Some of the affected members had digital abnormalities similar to those found in Pfeiffer syndrome, and in some cases the diagnosis of Apert syndrome might have seemed appropriate. However, as stated by Cohen, none of the affected individuals were reported to have thumb abnormalities. Jabs et al. demonstrated a mutation in the fibroblast growth factor receptor-2 (FGFR2) gene in this family. There was an alanine-to-glycine substitution in position 344 of the B exon of the FGFR2 gene. To date no other craniosynostosis cases with this mutation have been reported. Escobar and Bixler reported a further family where similar extreme variation in phenotype was seen; however, it has not yet been reported whether there is an FGFR2 mutation in this family. 9 refs.

    The magnetic properties of little examined CuCl2·2D2O are studied and compared with those of CuCl2·2H2O. New CuBr2·6H2O is also examined. Susceptibility maxima appear for chlorides at 5.35 and 5.50 K, in the above order, with estimated antiferromagnetic ordering at 4.15 and 4.25 K. Curie-Weiss fits yield g of 2.210 and 2.205, and Weiss θ of -6.0 and -4.7 K, respectively, in χM = C/(T - θ). One-dimensional Heisenberg model fits to susceptibilities, including interchain exchange in a mean-field approximation, are performed. Interchain exchange is significant but much weaker than intrachain. The bromide hexahydrate strongly differs magnetically from any chloride hydrate, but exhibits notable similarities and differences compared to previously studied CuBr2. A broad susceptibility maximum occurs near 218 K, only 4% lower than for CuBr2, but with almost twice the magnitude. Powder X-ray diffraction data for CuBr2·6H2O may be best accounted for by a monoclinic unit cell that is metrically orthorhombic. The volume per formula unit is consistent with trends in metal ionic radii. However, an alternative monoclinic cell with 5% smaller volume more readily rationalizes the magnetism.

    Permian and Meso-/Cenozoic salt formations are represented in wide parts of the German geologic underground (Reinhold & Hammer 2016). They are of interest for cavern storage of oil and gas as well as of renewable energies (in form of compressed air or hydrogen). For industrial exploration purposes, more detailed data about the composition, barrier properties, as well as the genesis and deformation of the rocks is needed. In central Northern Germany, salt rocks from the Upper Rotliegend are implemented in diapir structures together with salt formations from the Zechstein. Rotliegend salt rocks are characterized by halite that contains patches of detrital material which account for 5 to 60 vol.% of the rock. They show a characteristic red to purple color. Drill cores containing Rotliegend halite rocks from different locations were investigated in this study by using petrographical and microstructural methods. The halite shows different fabric types: (i) euhedral to hypidiomorphic grains with grain sizes up to several millimeters, (ii) polygonal grains with smaller grain sizes between 0.1 and 3 mm, and (iii) fibrous halite. Halite grain boundaries are decorated with fluid inclusions, especially around the contact to detrital material. Subgrains in halite are abundant in all investigated samples and show average sizes between 140 µm and 217 µm. These correspond to average differential stresses of 1 MPa to 1.45 MPa (Carter et al. 1993, Schléder & Urai 2005). The detrital material consists of clasts of quartz, feldspar, mica, carbonates and metal oxides with grain sizes of clay to silt fraction. In some samples, the detrital components show internal deformation by folding and fracturing. Depending on the location, different quantities of authigenic evaporite minerals, like carbonate and anhydrite, formed. Fractures are filled with halite, anhydrite and celestine. The different types of halite fabric are an indication of locally different deformational behavior of the

  13. Observation of Heavy Rydberg States in H_2 and HD

    2017-06-01

    The binding energies of the hydrogen atom are given by the Rydberg formula E_n = - {{R}_∞μ/m_e}/{(n-δ)^2}, where the quantum defect δ vanishes in the case of a pure Coulomb potential. Heavy Rydberg systems can be realized when the electron is replaced by an anion, which leads in the case of H^+H^- to an almost 1000 times larger Rydberg constant and to an infinite number of vibrational states. In the diabatic molecular basis, these ion-pair states are described by long-range Coulomb potentials with ^1Σ_g^+ and ^1Σ_u^+ symmetry. In this basis, the level energies are described by an almost energy-independent, nonzero quantum defect, reflecting the finite size of H^-. Strong interactions at small internuclear distances lead to strong variation of δ with n. Gerade [2] and ungerade [3] ion-pair states have been observed in H_2 with principal quantum numbers up to n=240. The quantum defects in this range were found to vary with energy, indicating the inadequacy of a pure diabatic picture. Spectra of ungerade heavy Rydberg states of H_2 with n=160-520 showing that the quantum defect only becomes energy independent for n>350 will be presented, supporting the description using a diabatic basis. I will also present first observations of ion-pair states in HD, showing two series of heavy Rydberg states, H^+D^- and H^-D^+, which have different series limits. The experimental results will be discussed and compared with calculations using both an adiabatic and a diabatic basis. [1] S. Pan, and F. H. Mies, J. Chem. Phys. 89, 3096 (1988). [2] M. O.

    Full Text Available The Cornell Net Carbohydrate and Protein System (CNCPS model has been increasingly used in tropical regions for dairy and beef production. However, the lack of appropriate characterization of the feeds has restricted its application. The objective of this study was to develop and evaluate a feed library containing feeds commonly used in tropical regions with characteristics needed as inputs for the CNCPS. Feed composition data collected from laboratory databases and from experiments published in scientific journals were used to develop this tropical feed library. The total digestible nutrients (TDN predicted at 1x intake of maintenance requirement with the CNCPS model agreed with those predicted by the Weiss et al. (1992 equation (r² of 92.7%, MSE of 13, and bias of 0.8% over all feeds. However, the regression r² of the tabular TDN values and the TDN predicted by the CNCPS model or with the Weiss equation were much lower (58.1 and 67.5%, respectively. A thorough comparison between observed and predicted TDN was not possible because of insufficient data to characterize the feeds as required by our models. When we used the mean chemical composition values from the literature data, the TDN predicted by our models did not agree with the measured values. We conclude using the TDN values calculated using the Weiss equation and the CNCPS model that are based on the actual chemical composition of the feeds result in energy values that more accurately represent the feeds being used in specific production situations than do the tabular values. Few papers published in Latin America journals that were used in this study reported information need by models such as the CNCPS.O uso do Sistema de Carboidrato e Proteina Líquidos da Universidade de Cornell (CNCPS tanto para produção de leite como carne tem aumentado durante o últimos anos nas regiões tropicais.

  15. The Anisotropic Aphid: Three-Dimensional Induction Modeling of Electrical Texture with Mixed Potentials

    Weiss, C. J.

    2014-12-01

    At the macroscopic scale, where the e-folding distance of low-frequency electromagnetic fields in conductive geomaterials is much larger than the size of organized heterogeneities such as fracture sets or laminations that constitute the geologic texture therein, electrical properties can be conveniently approximated by a generalized 3x3 tensor σ. Less convenient, however, are the algorithmic consequences of this approximation in electromagnetic modeling of 3D induction methods for geophysical exploration. Previous efforts at modelling generalized anisotropy with finite differences on a staggered Cartesian grid (e.g. Weiss and Newman, 2002; Wang and Fang, 2001) are posed in terms of the electric field with its governing "curl-curl" equation and well-documented null-space issues at low induction numbers. In contrast, Weiss (2013) proposed an alternate full-physics formulation in terms of Lorenz-gauged magentic vector A and electric scalar Φ potentials (Project APhiD) that eliminates the troublesome curl-curl operator, with ultrabroadband examples drawn from geologies with scalar, isotropic conductivity over the frequency range 10-2-1010 Hz. Here, the anisotropic theory presented in Weiss (2013) is implemented with finite differences on a Cartesian grid. Briefly stated, in this theoretical approach the conductivity tensor σ is split in terms of a rotationally-invariant isotropic conductivity σ* = ⅓ Tr(σ) and the residual σ - σ*I. This splitting decomposes the resulting finite difference coefficient matrix K into the sum Kiso + Kaniso, where the Kiso term is the coefficient matrix for the isotropic medium σ*, thus enabling reuse of the various routines previously developed for computing matrix coefficients in the isotropic case. Treatment of anisotropy is algorithmically therefore restricted to computing the coefficients in the sparse matrix Kaniso consisting of simple inner products of (σ - σ*I) · (A-∇Φ) and their divergence. In keeping with the

    We have reported magnetic properties of La1-xCoxMnO3 nanostructures synthesized by hydrothermal route. The crystal structure has been characterized by X-ray diffraction (XRD) technique, which shows rhombohedral perovskite structure at room temperature. Scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS) have been used to analyse morphology and chemical composition of prepared nanoparticles. Magnetic hysteresis loops of all the samples exhibit ferromagnetic behaviour at 10 K. Inverse susceptibility graphs as a function of temperature represent deviation from Curie Weiss law. The indication for short range ferromagnetic clusters well above Curie temperature is observed due to the Griffiths Phase (GP). It is proposed that the presence of GP arises from induced size effects of La and Co ions.

    2017-11-01

    For second countable discrete quantum groups, and more generally second countable locally compact quantum groups with trivial scaling group, we show that property (T) is equivalent to every weakly mixing unitary representation not having almost invariant vectors. This is a generalization of a theorem of Bekka and Valette from the group setting and was previously established in the case of low dual by Daws, Skalski, and Viselter. Our approach uses spectral techniques and is completely different from those of Bekka-Valette and Daws-Skalski-Viselter. By a separate argument we furthermore extend the result to second countable nonunimodular locally compact quantum groups, which are shown in particular not to have property (T), generalizing a theorem of Fima from the discrete setting. We also obtain quantum group versions of characterizations of property (T) of Kerr and Pichot in terms of the Baire category theory of weak mixing representations and of Connes and Weiss in terms of the prevalence of strongly ergodic actions.

    The authors examined achievement goal orientation (J. L. Duda & J. G. Nicholls, 1992), parental influence (M. L. Babkes & M. R. Weiss, 1999), and the parent-initiated motivational climate (S. A. White, 1996, 1998) in combination to broaden understanding of competitive male youth hockey players' (N = 259) perceptions of the parent-created sport climate and its relation to their self-reported good and poor sport behaviors (GPSB). Exploratory factor analysis revealed a multidimensional measure of GPSB. Multiple regression analyses indicated that athletes' GPSB were significantly predicted by different forms of parental influence. Canonical correlations revealed a complex picture of the contributions of goal orientation and the parent-created sport climate on boys' GPSB in youth hockey. Results expand knowledge of the influence that parents have in youth sport and emphasize the importance of understanding how children's interpretations of parental beliefs and behaviors affect their choices to engage in good and poor sport behaviors.

    β-TeVO4 crystallizes in the monoclinic space group P21/c. The spin structure is an arrangement of V zigzag double chains that run parallel to the c-axis and are formed by slightly distorted VO5 pyramids. Microscopic analysis identifies frustrated J1-J2 spin chains with sizable coupling in the bc plane and no frustrations. Magnetic susceptibility vs temperature experiments reveal a Curie-Weiss behavior with AFM correlations (θ ≈ -11 K) and a pronounced maximum at 14 K. A small anisotropy is observed between H ll b and H ll a,c, with b being the magnetic easy axis. Three anomalies are observed at 2.26 K, 3.28 K and 4.65 K in the magnetic susceptibility, however, the magnetic order corresponding to these transitions is currently unknown.

    The aim of this work is to investigate and compare ferro electrical properties of thin GeSbTe films with composition Ge{sub 4}Sb{sub 1}Te{sub 5} (with well defined ferro electrical properties) and Ge{sub 2}Sb{sub 2}Te{sub 5} using impedance, optical reflection, XRD, DSc and Piezo response Force Microscopy techniques. The temperature dependence of the capacitance in both materials shows an abrupt change at the temperature corresponding to ferroelectric-paraelectric transition and the Curie-Weiss dependence. In Ge{sub 2}Sb{sub 2}Te{sub 5} films this transition corresponds to the end from a NaCl-type to a hexagonal transformation. Piezo response Force Microscopy measurements found ferroelectric domains with dimension approximately equal to the dimension of grains. (Author)

    The influence of heat recovery on the disinfecting effect of composting of sewage sludge in a bio-reactor (in-vessel-composting) was investigated in a reactor type Weiss-system Kneer. As test agents 3 different serovars of salmonella, Parvo- and Poliovirus and eggs of Ascaris suum were used. The experiments were done in a reactor which was fed with dewatered municipal sewage sludge mixed with waste-paper as C-carrier for better composting. Even under winter conditions the test agents were inactivated within the time which is characteristic for the passage of the composting material through the plug-flow reactor. These results cannot simply be applied without further investigation to other reactors of the same type but with different ways of operation. (orig.)

    Full Text Available A perpendicular electric field breaks the layer symmetry of Bernal-stacked bilayer graphene, resulting in the opening of a band gap and a modification of the effective mass of the charge carriers. Using scanning tunneling microscopy and spectroscopy, we examine standing waves in the local density of states of bilayer graphene formed by scattering from a bilayer/trilayer boundary. The quasiparticle interference properties are controlled by the bilayer graphene band structure, allowing a direct local probe of the evolution of the band structure of bilayer graphene as a function of electric field. We extract the Slonczewski-Weiss-McClure model tight binding parameters as γ0 = 3.1 eV, γ1 = 0.39 eV, and γ4 = 0.22 eV.

    Dionne, Gerald F.

    1997-04-01

    At cryogenic temperatures magnetic properties of ferrites change significantly from their values at room temperature, which has been the main regime for most device applications. Recently, microwave ferrite devices with superconducting microstrip circuits have been demonstrated at a temperature of 77 K with virtually no electrical conduction losses. Conventional ferrimagnetic garnet and spinel compositions, however, are not generally optimized for low temperatures and may require chemical redesign if the full potential of these devices is to be realized. Saturation magnetizations increase according to the Brillouin-Weiss function dependence that is characteristic of all ferromagnetic materials. Increased magnetocrystalline anisotropy and magnetostriction can have large effects on hysteresis loop squareness and coercive fields that are essential for stable phase shift and efficient switching. Rare-earth impurities and other ions with short spin-lattice relaxation times can cause increased microwave losses. In this article, the basic magnetochemistry pertaining to ferrites will be examined for adaptation of ferrite technology to cryogenic environments.

    On-board processing (OBP) is one of significant satellite communication technologies, and the Asynchronous Transfer Mode (ATM) is widely used in the OBP which can guarantee the QoS. This article presents the CAC (Call Admission Control) algorithm and Congestion Control algorithm. We combine with B-CAC algorithm, Bahadur-Rao's theory, Weiss theory, to improve the old method, and the simulation results show that when the PDR/LR is small the burst is high, the chain utilization and statistic multiplexing gain get a big advantage. Besides, concerning TCP congestion control, the article compared five strategies: Tahoe, Reno, Newreno, Sack and Vegas. The simulation results show that the Vegas can be used to predict congestion conditions correctly; its congestion window (cwnd) control is smoother and is superior to other algorithms in average RTT.

    1985-01-01

    This unique overview by a prominent CalTech physicist provides a modern, rigorous, and integrated treatment of the key physical principles and techniques related to gases, liquids, solids, and their phase transitions. No other single volume offers such comprehensive coverage of the subject, and the treatment consistently emphasizes areas in which research results are likely to be applicable to other disciples. Starting with a chapter on thermodynamics and statistical mechanics, the text proceeds to in-depth discussions of perfect gases, electrons in metals, Bose condensation, fluid structure, potential energy, Weiss molecular field theory, van der Waals equation, and other pertinent aspects of phase transitions. Many helpful illustrative problems appear at the end of each chapter, and annotated bibliographies offer further guidance.

    We carried out inelastic neutron scattering experiments on a buckled honeycomb lattice antiferromagnet Ba2NiTeO6 exhibiting a stripe structure at a low temperature. Magnetic excitations are observed in the energy range of ℏω≲10 meV having an anisotropy gap of 2 meV at 2 K. We perform spin-wave calculations to identify the spin model. The obtained microscopic parameters are consistent with the location of the stripe structure in the classical phase diagram. Furthermore, the Weiss temperature independently estimated from a bulk magnetic susceptibility is consistent with the microscopic parameters. The results reveal that a competition between the nearest-neighbor and next-nearest-neighbor interactions that together with a relatively large single-ion magnetic anisotropy stabilize the stripe magnetic structure.

    Many graduates of the Harvard Medical Unit (HMU) at Boston City Hospital, in either the clinical training/residency program or the research program at the Thorndike Memorial Laboratory, contributed in major ways to the HMU and constantly relived their HMU experiences. The HMU staff physicians, descending from founder and mentor physicians Francis W. Peabody, Soma Weiss, and George R. Minot, were dedicated to the teaching, development, and leadership of its clinical and research trainees, whose confidence and dedication to patient care as a result of their mentorship led many to lifelong achievements as clinicians, teachers, and mentors. Their experience also led to a lifelong love of the HMU (despite its loss), camaraderie, happiness, and intense friendships with their associates.

    Magnetic susceptibility measurements between 4.2 and 300 K for R{sub 2}BaCuO{sub 5} compounds (R = Dy, Y and Yb), also called green phases, reveal the existence of antiferromagnetic ordering in the copper sublattice around 30 K. At lower temperatures {chi} vs. T plots show in all cases the existence of a sharp maximum, which can be attributed to the onset of antiferromagnetic ordering in the rare earth sublattice, probably induced by the polarization of Cu{sup +2} ions. Experimental magnetic moments estimated from the Curie-Weiss region generally agree with the theoretical values expected for thee R{sup +3} ions. High-resolution transmission electron microscopy and electron diffraction experiments confirm the earlier proposed structures for the R{sub 2}BaCuO{sub 5}, and show the existence of a well ordered material.

    2017-11-01

    Using thermodynamic measurements, neutron diffraction, nuclear magnetic resonance, and muon spin relaxation, we establish putative quantum spin-liquid behavior in Ba3InIr2O9 , where unpaired electrons are localized on mixed-valence Ir2O9 dimers with Ir4.5 + ions. Despite the antiferromagnetic Curie-Weiss temperature on the order of 10 K, neither long-range magnetic order nor spin freezing are observed down to at least 20 mK, such that spins are short-range correlated and dynamic over nearly three decades in temperature. Quadratic power-law behavior of both the spin-lattice relaxation rate and specific heat indicates the gapless nature of the ground state. We envisage that this exotic behavior may be related to an unprecedented combination of the triangular and buckled honeycomb geometries of nearest-neighbor exchange couplings in the mixed-valence setting.

    1982-01-01

    The “gasometer” is a device that measures differential dissolved-gas pressures (δP) in water relative to barometric pressure (as does the “Weiss saturometer”), but operates continuously without human attention. The gasometer can be plumbed into a water-supply system and requires 8 liters/minute of water or more at 60 kilopascals. The gasometer's surfaces are nontoxic, and flow-through water can be used for fish culture. The gasometer may be connected to a small submersible pump and operated as a portable unit. The gasometer can activate an alarm system and thus protect fish from hyperbaric (supersaturation) or hypobaric gas pressures (usually due to low dissolved oxygen). Instructions are included for calculating and reporting data including the pressure and saturation of individual gases. Construction and performance standards are given for the gasometer. Occasional cleaning is required to remove biofouling from the gas-permeable tubing.PDF

    2015-10-01

    We investigate the magnetic properties of spin-1/2 charged Fermi gases with ferromagnetic coupling via mean-field theory, and find the interplay among the paramagnetism, diamagnetism and ferromagnetism. Paramagnetism and diamagnetism compete with each other. When increasing the ferromagnetic coupling the spontaneous magnetization occurs in a weak magnetic field. The critical ferromagnetic coupling constant of the paramagnetic phase to ferromagnetic phase transition increases linearly with the temperature. Both the paramagnetism and diamagnetism increase when the magnetic field increases. It reveals the magnetization density bar M increases firstly as the temperature increases, and then reaches a maximum. Finally the magnetization density bar M decreases smoothly in the high temperature region. The domed shape of the magnetization density bar M variation is different from the behavior of Bose gas with ferromagnetic coupling. We also find the curve of susceptibility follows the Curie-Weiss law, and for a given temperature the susceptibility is directly proportional to the Landé factor.

    Full Text Available We investigate the classical Zassenhaus Conjecture (ZC for integral group rings of alternating groups A9 and A10. Even the question (ZC remains open as no counterexample is known up to date, it been confirmed for special types of groups such as nilpotent groups by Roggenkamp, Scot and Weiss. However, a new method based on the partial augmentation of torsion units been established by Luthar and Passi to confirm the (ZC for A5. Later a weaker version of (ZC was proposed in 2007, we call it the Prime Graph Conjecture (PGC about the Gruenberg-Kegel (prime graph of the group of all normalized units of the integral group ring of a finite group. Recently, the (PGC has a positive answer for solvable groups, Frobenius groups and several simple groups. Here, as a consequence of our results, we confirm the (PGC for integral group rings of alternating groups An for all n<11.

    Mori, Takashi

    2012-08-01

    We study equilibrium states of quantum spin systems with nonadditive long-range interactions by adopting an appropriate scaling of the interaction strength, i.e., the so-called Kac prescription. In classical spin systems, it is known that the equilibrium free energy is obtained by minimizing the free-energy functional over the coarse-grained magnetization. Here we show that it is also true for quantum spin systems. From this observation, it is found that when the canonical ensemble and the microcanonical ensemble are not equivalent in some parameter region, it is not necessarily justified to replace the actual long-range interaction by the infinite-range interaction (Curie-Weiss-type interaction). On the other hand, in the parameter region where the two ensembles are equivalent, this replacement is always justified. We examine the Heisenberg XXZ model as an illustrative example and discuss the relation to experiments.

    Full Text Available The temperature dependence of the spontaneous polarization P is calculated in the ferroelectric phase of KH2PO4 (KDP at atmospheric pressure (TC = 122 K. Also, the dielectric constant ε is calculated at various temperatures in the paraelectric phase of KDP at atmospheric pressure. For this calculation of P and ε, by fitting the observed Raman frequencies of the soft mode, the microscopic parameters of the pure tunnelling model are obtained. In this model, the proton-lattice interaction is not considered and the collective proton mode is identified with the soft-mode response of the system. Our calculations show that the spontaneous polarization decreases continuously in the ferroelectric phase as approaching the transition temperature TC. Also, the dielectric constant decreases with increasing temperature and it diverges in the vicinity of the transition temperature (TC = 122 K for KDP according to the Curie-Weiss law.

    We present a 6-year-old boy with a virilizing adrenocortical tumor who initially presented with peripheral precocious puberty. Development of facial acne, pubic hair and a growth spurt were noted at the age of five. A low-pitched voice as well as maturation of external genitalia was noted at the age of six. Both serum and urinary levels of adrenal androgens were elevated. Abdominal computed tomography revealed a large right suprarenal mass and he underwent surgical resection without any complications. The histological diagnosis was adrenocortical carcinoma according to the criteria of Weiss. Following surgical removal of the androgen-producing tumor, the patient subsequently developed hypothalamic-pituitary activation and demonstrated central precocious puberty. He was treated with a gonadotropin-releasing hormone agonist in order to delay further pubertal progression. Clinical follow-up of potential secondary effects of excess hormone secretion after removal is important in some pediatric patients with virilizing adrenocortical tumor.

  7. Evolutionary Mechanisms for Loneliness

    2013-01-01

    Robert Weiss (1973) conceptualized loneliness as perceived social isolation, which he described as a gnawing, chronic disease without redeeming features. On the scale of everyday life, it is understandable how something as personally aversive as loneliness could be regarded as a blight on human existence. However, evolutionary time and evolutionary forces operate at such a different scale of organization than we experience in everyday life that personal experience is not sufficient to understand the role of loneliness in human existence. Research over the past decade suggests a very different view of loneliness than suggested by personal experience, one in which loneliness serves a variety of adaptive functions in specific habitats. We review evidence on the heritability of loneliness and outline an evolutionary theory of loneliness, with an emphasis on its potential adaptive value in an evolutionary timescale. PMID:24067110

    In this work, we have presented the generalized phase diagrams of the van Hemmen model for spin S=1 in the presence of an anisotropic term of random crystalline field. In order to study the critical behavior of the phase transitions, we employed a mean-field Curie–Weiss approach, which allows calculation of the free energy and the equations of state of the model. The phase diagrams obtained here displayed tricritical behavior, with second-order phase transition lines separated from the first-order phase transition lines by a tricritical point. - Highlights: • Several phase diagrams are obtained for the model. • The influence of the random crystalline anisotropy field on the model is investigated. • Three ordered (spin-glass, ferromagnetic and mixed) phases are found. • The tricritical behavior is examined.

    We present a high-pressure NMR study of the overdoped iron pnictide superconductor NaFe0.94Co0.06As. The low-energy antiferromagnetic spin fluctuations in the normal state, manifest as the Curie-Weiss upturn in the spin-lattice relaxation rate 1/(75)T1T, first increase strongly with pressure but fall again at P>Popt=2.2  GPa. Neither long-ranged magnetic order nor a structural phase transition is encountered up to 2.5 GPa. The superconducting transition temperature Tc shows a pressure dependence identical to the spin fluctuations. Our observations demonstrate that magnetic correlations and superconductivity are optimized simultaneously as a function of the electronic structure, thereby supporting very strongly a magnetic origin of superconductivity.

    Full Text Available We consider an open-loop system of a fourth order Schrodinger equation with variable coefficients and Neumann boundary control and collocated observation. Using the multiplier method on Riemannian manifold we show that that the system is well-posed in the sense of Salamon. This implies that the exponential stability of the closed-loop system under the direct proportional output feedback control and the exact controllability of open-loop system are equivalent. So in order to conclude feedback stabilization from well-posedness, we study the exact controllability under a uniqueness assumption by presenting the observability inequality for the dual system. In addition, we show that the system is regular in the sense of Weiss, and that the feedthrough operator is zero.

    This paper develops a framework for the design of failure detection and isolation (FDI) algorithms. Rather than trying to apply 'optimal' techniques in a top-down manner, the system redundancies are evaluated with respect to their ability to provide reliable FDI information. Previous work of Pattipati et al. (1984) and Weiss et al. (1984) defined a useful context and several useful analytical results, which provide a basis for the FDI design methodology developed here. A general decision structure which can take advantage of redundancy evaluation is presented, and examples of typical design considerations are discussed. The operation of the decision structure is then demonstrated for a sensor FDI application involving the F-100 jet engine.

    The concentrations of the inorganic chemical elements presents in archaeological ceramic samples and clay samples allows the study about the clay sources determination used in the ceramic production. The analyzed samples are fragments of Brazilian indigenous ceramic, found in the area of the city of Londrina, North of Parana, and they belong to the archaeological collection of the 'Padre Carlos Weiss' Historical Museum, of the State University of Londrina. The determination of the chemical elements in these fragments was performed by energy dispersive X-ray microfluorescence ({mu}-XRF), for being not destructive and multielementar. The analytic technique allowed the identification of the K, Ca, Ti, Mn, Fe minority elements, and the Cr, Ni, Cu, Zn and Rb trace elements. The cluster analysis for the method of the medium grouping was used, and it was obtained two different groups, taking to conclude that indigenous Tupiguaranis used two clay sources in the making of its ceramic.

    We have performed {sup 75}As, {sup 139}La, and {sup 57}Fe Nuclear Magnetic Resonance (NMR) measurements on the new LaO{sub 1-x}F{sub x}FeAs superconductor. For x=0.1, NMR on all three nuclei shows that the local electronic susceptibility increases with increasing temperature in the normal state. The scaling of all NMR shifts with respect to the macroscopic susceptibility indicates a single spin liquid. Relaxation measurements exhibit a similar temperature-dependence for (T{sub 1}T){sup -1}, and suggest that the dynamical susceptibility changes uniformly in q space with varying temperature. For x=0.05, in the underdoped regime, we find a Curie Weiss like increase of (T{sub 1}T){sup -1} at low temperatures, indicating the onset of local moment fluctuations.

    This paper reports DFT-computed electronic ground states, Mössbauer isomer shifts, O-O and Fe-O vibration frequencies, and thermodynamics of O2-binding of heme models representing different distal (position E7) interactions, strictly validated against experimental data. Based on the results......, the impact of specific types of distal interactions on oxyheme electronic structure can be systematized. Hydrogen bonding increases back donation, O-O bond activation, and oxygen binding affinity. The heme side-chains reduce isomer shifts by -0.06 mm/s due to electron-withdrawal from iron, and distal......-O bond length does not correlate with O2-affinity, as hydrogen bonding elongates both Fe-O and O-O bonds by ~0.01-0.02 Å, contrary to the situation absent of distal hydrogen bonds and of potential relevance to ligand-activation where distal interactions are involved. An ionic (Weiss-type) model of Fe...

    In the framework of the IEA Task 32 (Solar Heating and Cooling Programme), we developed a numeric model to simulate heat transfer in phase change materials (PCM), and experimental data. The analyzed system is bulk PCM plunged in a water tank storage of a solar combisystem (heating and domestic hot water production). The numerical model, based on the enthalpy approach, takes into account hysteresis and subcooling characteristic and also the conduction and the convection in the PCM. This model has been implemented in an existing TRNSYS type of water tank storage. The simulations has been compared with experimental data obtained with a solar installation using water tank storage of about 900 litres, already studied during the IEA Task 26 (Weiss 2003).

    Social interaction and development of friendships between children with and without a disability are often proposed as potential outcomes of inclusive education. Physical activity specialists assert that exercise and sport environments may be conducive to social and friendship outcomes. This study investigated friendship in inclusive physical education from the perspective of students with (n = 8) and without (n = 8) physical disabilities. All participants attended a reversely integrated school and were interviewed using a semistructured, open-ended format. An adapted version of Weiss, Smith, and Theeboom's (1996) interview guide exploring perceptions of peer relationships in the sport domain was used. Four conceptual categories emerged from the analysis: development of friendship, best friend, preferred physical activities and outcomes, and dealing with disability. The results demonstrated the key characteristics of best friends and the influential role they play.

    In this paper we have shown a potential approach to fabricate relaxor materials by making a ceramic composite of environmental friendly Ba-based diffuse ferroelectric BaZr{sub x}Ti{sub 1-x}O{sub 3} (x = 0.20 and 0.25) with non-ferroelectric magnesium oxide (MgO). The dielectric behaviour of BaZr{sub x}Ti{sub 1-x}O{sub 3} : 50 wt% MgO (x = 0.20 and 0.25) composites has been studied in the temperature range from 300-11 K. The degree of relaxation ({gamma}) has been estimated using the modified Curie-Weiss law. The dielectric relaxation rate follows the Vogel-Fulcher relation with a characteristic cooperative freezing at a specific temperature. These BaZr{sub x}Ti{sub 1-x}O{sub 3} composites have also shown strong dc electric field dependent dielectric behaviour.

    We report magneto-transport and magnetic properties of (1-x)La{sub 0.7}Ca{sub 0.3}MnO{sub 3}+xAl{sub 2}O{sub 3} composites synthesized through a solid-state reaction method combined with a high energy milling method. Most interestingly, the effective magnetic anisotropy is found to decrease with increase in the non-magnetic insulating Al{sub 2}O{sub 3} phase fraction in the composites. In addition, we observed that the magnitude of low-field magnetoresistance arising from spin-polarized tunneling of conduction electrons, as well as that of high-field magnetoresistance, displays a Curie-Weiss law-like behavior. Finally, we found that the temperature dependence of low and high-field magnetoresistance is controlled predominantly by the nature of temperature response of surface magnetization of the particles.

    We present the magnetic properties of silica-supported metal (Fe,catalyst) nanoparticles synthesized by precipitation of metal nitrate in ammonia-based medium. Our goal is the study of possible metal-support interactions in the nanoporous catalyst. The temperature dependence of the magnetization for all samples display spin-glass like behavior below c.a. 11-12 K, with clear Curie-Weiss dependence in the high-temperature regime. Spin-glass-like behavior was inferred from dynamic AC susceptibility data after analyzing the frequency-dependence of the in-phase component {chi}'(f) by the expression W = {Delta}T{sub f}/[T{sub f} {Delta}log(f)] = 3.0 x 10{sup -3}. We found that the magnetic behavior of the catalyst is drastically affected by the existence of interactions between the metal and the support.

Teil der Artikelserie wurde die Zeit behandelt, in der das Gesamtgebiet der Geowissenschaften von dem Mineralogen und Kristallographen Christian Samuel Weiss im Mineralogischen Museum vertreten wurde und in der sich die Spezialisierung in Teilgebiete durch auftretende weitere Lehrkräfte zeigte. Nach dem Tod von Weiss im Jahre 1856 wirkte sich diese Entwicklung auch auf die Leitung des Mineralogischen Museums aus und führte schließlich zur Teilung in zwei Institutionen. Der vorliegende Artikel, der bis zum 100jährigen Jubiläum der Universität im Jahre 1910 reicht, behandelt dies in folgenden Kapiteln: 1 das Mineralogische Museum unter dem Mineralogen Gustav Rose als Direktor und dem Geologen und Paläontologen Ernst Beyrich in der Zeit von 1856 bis 1873, 2 das Mineralogische Museum unter Ernst Beyrich als Direktor, dem Mineralogen Martin Websky und dem Geologen und Petrographen Justus Roth in den Jahren von 1873 bis 1888 nebst Aufteilung in zwei Institutionen, 3 die Projektierung und den Bau des Museums für Naturkunde in den Jahren von 1873 bis 1889, 4 die beiden geowissenschaftlichen Institutionen in den Jahren 1888 bis 1910, 4a das Geologisch-Paläontologische Institut und Museum unter den Geologen und Paläontologen Ernst Beyrich, Wilhelm Dames und Wilhelm Branco (Branca nacheinander als Direktoren und 4b das Mineralogisch-Petrographische Institut und Museum unter dem Mineralogen und Petrographen Carl Klein und danach dem Mineralogen und Kristallographen Theodor Liebisch als Direktoren. The preceding fourth part of this series of articles dealt with the period (of time, when the whole field of earth sciences in the Mineralogical Museum was represented by one person, the mineralogist and crystallographer Christian Samuel Weiss.

    The fulfilment of the Curie and Curie-Weiss laws for a magnetic dispersive nanosystem is critically discussed. Results of investigations into the temperature dependences of the magnetic susceptibility of these media are presented for a wide range of dispersive phase concentrations. Based on the results of these investigations, the validity of these laws for the χ/μ and χ-1 is checked. A conclusion is drawn that the Curie law is valid only for colloids with a certain limited range of magnetic nanoparticle concentrations due to difference in magnitudes of the external magnetic field and the field acting on an individual nanoparticle (effective field). The effective field parameter is calculated in the context of the effective field theory. It is indicated that the value of the effective field parameter is not a constant and depends on the concentration of magnetic nanoparticles and on the temperature of the disperse medium as a whole.

    Water is characterized by large molecular electric dipole moments and strong interactions between molecules; however, hydrogen bonds screen the dipole-dipole coupling and suppress the ferroelectric order. The situation changes drastically when water is confined: in this case ordering of the molecular dipoles has been predicted, but never unambiguously detected experimentally. In the present study we place separate H2O molecules in the structural channels of a beryl single crystal so that they are located far enough to prevent hydrogen bonding, but close enough to keep the dipole-dipole interaction, resulting in incipient ferroelectricity in the water molecular subsystem. We observe a ferroelectric soft mode that causes Curie-Weiss behaviour of the static permittivity, which saturates below 10 K due to quantum fluctuations. The ferroelectricity of water molecules may play a key role in the functioning of biological systems and find applications in fuel and memory cells, light emitters and other nanoscale electronic devices.

    The authors tested a model, inspired by affective events theory (H. M. Weiss & R. Cropanzano, 1996), that examines the dynamic nature of emotions at work, work attitudes, and workplace deviance. Sixty-four employees completed daily surveys over 3 weeks, reporting their mood, job satisfaction, perceived interpersonal treatment, and deviance. Supervisors and significant others also evaluated employees' workplace deviance and trait hostility, respectively. Over half of the total variance in workplace deviance was within-individual, and this intraindividual variance was predicted by momentary hostility, interpersonal justice, and job satisfaction. Moreover, trait hostility moderated the interpersonal justice-state hostility relation such that perceived injustice was more strongly related to state hostility for individuals high in trait hostility.

  10. Spin glass behavior of isolated, geometrically frustrated tetrahedra of iron atoms in the intermetallic La(21)Fe(8)Sn(7)C(12).

    Metal flux synthesis in a low-melting eutectic mixture of lanthanum and nickel has produced a family of complex intermetallic carbide phases. La(21)Fe(8)M(7)C(12) (M = Sn, Bi, Sb, Te, Ge) has a new cubic structure featuring tetrahedra of iron atoms capped with carbon on each edge. These tetrahedra are surrounded by a La/M framework and are therefore isolated from each other. The antiferromagnetic coupling of the iron atoms is frustrated by their ideal tetrahedral arrangement; this is evidenced by magnetic susceptibility measurements on the La(21)Fe(8)Sn(7)C(12) analogue. Deviations from Curie-Weiss behavior begin at 100 K; variation in field-cooled vs zero-field-cooled behavior is seen at 5 K indicative of magnetic ordering. AC susceptibility data indicate that the temperature of this transition is frequency-dependent, behavior characteristic of spin glass systems.

    This motivating textbook gives a friendly, rigorous introduction to fundamental concepts in equilibrium statistical mechanics, covering a selection of specific models, including the Curie–Weiss and Ising models, the Gaussian free field, O(n) models, and models with Kać interactions. Using classical concepts such as Gibbs measures, pressure, free energy, and entropy, the book exposes the main features of the classical description of large systems in equilibrium, in particular the central problem of phase transitions. It treats such important topics as the Peierls argument, the Dobrushin uniqueness, Mermin–Wagner and Lee–Yang theorems, and develops from scratch such workhorses as correlation inequalities, the cluster expansion, Pirogov–Sinai Theory, and reflection positivity. Written as a self-contained course for advanced undergraduate or beginning graduate students, the detailed explanations, large collection of exercises (with solutions), and appendix of mathematical results and concepts also make i...

    Geometrical frustration, arising from the unsatisfying magnetic bonds in peculiar magnetic materials, leads to the emergence of a variety of ground states ranging from exotic disordered (quantum spin liquid) to unusual magnetic ordered states. We have prepared and studied the magnetic properties of a novel quantum magnet PbCuTeO5, whose structure suggests that it has 2D distorted check-board lattice. A large antiferromagnetic Curie-Weiss temperature of -165 K and a spin freezing temperature Tf = 6 K are observed in the magnetic data. Our results suggest that PbCuTeO5 is a new frustrated quantum magnet with a large frustration parameter f = θCW/Tf > 27.

    Substitution of zinc nonmagnetic impurities in copper site of conductive planes in the compound YBa{sub 2}Cu{sub 3}O{sub 7} constitute a probe for studying the magnetism role in superconductivity apparition. This zinc substitution effects are put in evidence by neutrons and X-rays diffraction. Neel temperature of zinc substituted isolating compounds is lowered, this is attributed to zinc dilution effect of the bidimensional antiferromagnetic structure. Curie-Weiss type magnetic comportment in planes copper site, and the screening of the structural effects by the doping substitution indicate a reduction of the charges carriers. Nickel substitution induces along the c axis an important reduction of the lattice parameter, and a doubling of the magnetic lattice. This is attributed to nickel partial substitution in copper sites non affecting the charges transfer. (A.B.). 219 refs.

    This textbook provides an exposition of equilibrium thermodynamics and its applications to several areas of physics with particular attention to phase transitions and critical phenomena. The applications include several areas of condensed matter physics and include also a chapter on thermochemistry. Phase transitions and critical phenomena are treated according to the modern development of the field, based on the ideas of universality and on the Widom scaling theory. For each topic, a mean-field or Landau theory is presented to describe qualitatively the phase transitions. These theories include the van der Waals theory of the liquid-vapor transition, the Hildebrand-Heitler theory of regular mixtures, the Griffiths-Landau theory for multicritical points in multicomponent systems, the Bragg-Williams theory of order-disorder in alloys, the Weiss theory of ferromagnetism, the Néel theory of antiferromagnetism, the Devonshire theory for ferroelectrics and Landau-de Gennes theory of liquid crystals.

    Full Text Available We give conditions under which two solutions x and y of the Kolmogorov equation x˙=xf(t,x satisfy limy(t/x(t=1 as t→∞. This conclusion is important for two reasons: it shows that the long-time behavior of the population is independent of the initial condition and it applies to ecological systems in which the coefficients are time dependent. Our first application is to an equation of Weissing and Huisman for growth and competition in a light gradient. Our second application is to a nonautonomous generalization of the Turner-Bradley-Kirk-Pruitt equation, which even before generalization, includes several problems of ecological interest.

  18. The Utility of Iron Chelators in the Management of Inflammatory Disorders

    Directory of Open Access Journals (Sweden)

    C. Lehmann

    2015-01-01

    Full Text Available Since iron can contribute to detrimental radical generating processes through the Fenton and Haber-Weiss reactions, it seems to be a reasonable approach to modulate iron-related pathways in inflammation. In the human organism a counterregulatory reduction in iron availability is observed during inflammatory diseases. Under pathological conditions with reduced or increased baseline iron levels different consequences regarding protection or susceptibility to inflammation have to be considered. Given the role of iron in development of inflammatory diseases, pharmaceutical agents targeting this pathway promise to improve the clinical outcome. The objective of this review is to highlight the mechanisms of iron regulation and iron chelation, and to demonstrate the potential impact of this strategy in the management of several acute and chronic inflammatory diseases, including cancer.

    2014-07-01

    We present a detailed direct numerical simulation of statistically steady, homogeneous, isotropic, two-dimensional magnetohydrodynamic turbulence. Our study concentrates on the inverse cascade of the magnetic vector potential. We examine the dependence of the statistical properties of such turbulence on dissipation and friction coefficients. We extend earlier work significantly by calculating fluid and magnetic spectra, probability distribution functions (PDFs) of the velocity, magnetic, vorticity, current, stream-function, and magnetic-vector-potential fields, and their increments. We quantify the deviations of these PDFs from Gaussian ones by computing their flatnesses and hyperflatnesses. We also present PDFs of the Okubo-Weiss parameter, which distinguishes between vortical and extensional flow regions, and its magnetic analog. We show that the hyperflatnesses of PDFs of the increments of the stream function and the magnetic vector potential exhibit significant scale dependence and we examine the implication of this for the multiscaling of structure functions. We compare our results with those of earlier studies.

    2017-12-01

    The properties of MnO have been calculated using generalised gradient approximation (GGA-) and hybrid (h-) density functional theory (DFT), specifically variants of the popular PBE and PBESol exchange-correlation functionals. The GGA approaches are shown to be poor at reproducing experimental magnetic coupling constants and rhombohedral structural distortions, with the PBESol functional performing worse than PBE. In contrast, h-DFT results are in reasonable agreement with experiment. Calculation of the Néel temperatures using the mean-field approximation gives overestimates relative to experiment, but the discrepancies are as low as 15 K for the PBE0 approach and, generally, the h-DFT results are significant improvements over previous theoretical studies. For the Curie-Weiss temperature, larger disparities are observed between the theoretical results and previous experimental results.

    Spontaneous total avascular necrosis of the tarsal navicula has been well documented in children (Kohler's disease) but is uncommon in adults where partial necrosis is usually seen after trauma or in Müller-Weiss disease. A case of spontaneous complete navicular osteonecrosis in a 46 year old female is described; she had accompanying Mee's leuchonychial lines in the toenails of the great and second toes only; the lines resolved after 9 months. She has been treated with an excision of the navicula and interpositional iliac crest bone graft talo-cuneiform fusion with resolution of her pain. It is postulated that the combination of the Mee's lines and avascular necrosis of the navicula indicates an occlusion of the dorsalis pedis in a predisposed individual.

    Full Text Available Lithium-based cells LiCo2O4 have been characterized by magnetic techniques, looking at the influence of the partial substitution of cobalt by 3d or 4d transition metal elements (Fe, Ni, Cu, Cr, Mo. The non-substituted compound LiCo2O4 behaves as an antiferromagnet, with a Néel temperature TN of 30 K, although antiferromagnetic interactions are much more important, as suggested by a Weiss parameter Θ of the order of ‑225 K. In the solid solution Li(NixCo2‑xO4 the Weiss parameter Θ changes with x(Ni, reaching large positive values (e.g., Θ ~ +230 K, for x = 0.5. This phenomenon suggests the existence of a canted‑antiferromagnetic or ferrimagnetic structures with large ferromagnetic components. Substitution of cobalt by other 3d or 4d transition metals in the LiMe0.5Co1.5O4 series shows dramatic effects with respect to the non-substituted LiCo2O4 compound : copper completely suppresses the magnetic order, while iron increases TN to almost room temperature. No modifications are observed when molybdenum substitutes cobalt, while chromium transforms the AF order in a ferromagnetic one, with Tc of about 90 K.Se ha caracterizado por técnicas magnéticas, el efecto de la sustitución parcial de Co por elementos de transición 3d o 4d (Fe, Ni, Cu, Cr, Mo en celdas LiCo2O4 a base de litio.

En la solución sólida Li(NixCo2‑xO4, el parámetro de Weiss Θ cambia con x(Ni, alcanzando valores positivos altos (e.g., Θ ~ +230K, para x=0.5.

    The synthesis of rubidium heptachlorodiuranate(III) together with some of its structural, spectroscopic, and magnetic properties are reported. Unit cell parameters were determined from X-ray powder diffraction data. Uranium(3+) doped single crystals of RbY2Cl7have been grown by the Bridgman-Stockbarger method. The Raman and infrared spectra of RbU2Cl7as well as the electronic absorption spectrum of RbY2Cl7: U3+(1%) at 4.2 K have been recorded and are discussed. Magnetic susceptibility measurements were carried out by the Faraday method in the 4.2-300 K range. The Curie-Weiss law is followed in the 210-300 K range with the paramagnetic constants μeff= 3.74 μB,C= 1.750 emu·K·mole-1, and θ = -80 K.

    A large variety of solar combi systems are on the marked to day. The best performing systems are highly advanced energy systems with thermal stratification manifolds, an efficient boiler and only one control system, which controls both the boiler and the solar collector loop (Weiss et al., 2003......). However, it is still too early to draw conclusions on the design of solar combi systems. Among others, the following questions needs to be answered: Is an external domestic hot water preparation more desirable than an internal domestic hot water preparation? Is a stratification manifold always more...... desirable than a fixed inlet position? This paper presents experimental investigations of an advanced solar combi system with thermal stratification manifold inlets both in the solar collector loop and in the space heating system and with an external domestic hot water preparation.

    Graphical abstract: Modified Curie–Weiss law fitting of BT1, NBT1, NBT2 and NBT3 samples and inset shows modified Curie–Weiss law fitting for NBT at 10 kHz frequency. Highlights: ► For the first time we have studied the effect of Nd{sup 3+} and BT on structural changes in NBT lattice. ► Ti metal powder was used instead of TiO{sub 2} to synthesize the ceramics using sol–gel. ► FTIR and Raman spectra were recorded for NBT–BT based ceramics. ► In dielectric measurements the transition from relaxor to normal with doping is observed. -- Abstract: Lead free relaxor NBT–BT based ceramic compositions were prepared using sol–gel method. The samples were sintered around 1140 °C for 3–4 h in the air. The characterization was done using X-ray diffraction (XRD), filed emission scanning electron microscope (FESEM), energy dispersive spectrometry (EDS), Raman, Fourier transform infrared (FTIR), dielectric and P–E loop measurements. The XRD patterns recorded at room temperature confirmed the phase formation of the samples. From FESEM micrographs, the particle sizes were estimated for calcined powders and are found to be in the range of 50–70 nm. The analysis of both Raman and FTIR spectral data of the samples also indicated the distortion of NBT lattice with the addition of Ba{sup 2+} and Nd{sup 3+} ions. It was found that the dielectric and piezoelectric properties of NBT–BT compositions beyond the morphotrophic phase boundary (MPB) are rather sensitive to the presence of tetragonal phase in addition to the rhombohedral phase. NBT ceramics exhibit a decrease in diffusive factor with increasing BT content, implying a degradation of relaxor feature leading to the normal ferroelectric nature. The ceramic samples employed in the present study exhibited variation in P–E hysteresis loops.

    Full Text Available This mini-review describes electrical conductivity, magnetic properties, and magnetotransport properties of one-dimensional partially oxidized salts composed of axially ligated phthalocyanines, TPP[M(Pc(CN2]2 (TPP = tetraphenylphosphonium, Pc = phthalocyaninato, with M of Fe (d5, S = 1/2 and Cr (d3, S = 3/2. These salts are isomorphous, and π–π interactions in the crystal, that becomes the origin of the charge carriers, are nearly the same. Both the Fe and Cr salts show carrier localization and charge disproportionation which is enhanced by the interaction between local magnetic moments and conduction π-electrons (π–d interaction. However, the magnetic properties are slightly different between them. M = Fe has been found to show unique anisotropic magnetic properties and antiferromagnetic short-range magnetic order between the d-spins. On the other hand, for M = Cr, its magnetic moment is isotropic. Temperature dependence of the magnetic susceptibility shows typical Curie–Weiss behavior with negative Weiss temperature, but the exchange interaction is complicated. Both M = Fe and M = Cr show large negative magnetoresistance, reflecting the difference in the anisotropy. The magnetoresistance ratio (MR is larger in the Fe system than in the Cr system in the low magnetic field range, but MR in the Cr system exceeds that in the Fe system when the magnetic field becomes higher than 15 T. We discuss the mechanism of the giant negative magnetoresistance with reference to the d–d, π–d, and π–π interactions.

  9. NMR evidence for spin fluctuations in underdoped LaO{sub 1-x}F{sub x}FeAs

    We present {sup 75}As Nuclear Magnetic Resonance (NMR) measurements on the iron-based superconductor LaO{sub 1-x}F{sub x}FeAs with 0 {<=} x {<=} 0.1, covering a broad range of the phase diagram from magnetically-ordered to optimally-doped superconducting samples. For underdoped samples (x=0.05,x=0.075) the {sup 75}As NMR spin-lattice relaxation rate (T{sub 1}T){sup -1} shows a Curie-Weiss-like increase at intermediate temperatures, indicating the slowing down of spin fluctuations. However, a simple Curie-Weiss fit fails to describe (T{sub 1}T){sup -1}(T) above 250 K and the occurrence of a peak in (T{sub 1}T){sup -1} slightly above T{sub c}. Instead, the data can be well described by considering a BPP-model for fluctuating magnetic fields in combination with a doping-independent linear temperature dependence at high temperature. At optimal doping (x=0.1) spin fluctuations are suppressed and only the linear contribution to (T{sub 1}T){sup -1} is left. This stands in contrast to other pnictides, such as Ba(Fe{sub 1-x}Co{sub x}As){sub 2} and Ba(FeAs{sub 1-x}P{sub x}){sub 2}. Our analysis is consistent with charge carrier localization in underdoped LaO{sub 1-x}F{sub x}FeAs as seen by means of resistivity measurements.

    Full Text Available Doped BaTiO3-ceramics is very interesting for their application as PTCR resistors, multilayer ceramic capacitors, thermal sensors etc. Ho doped BaTiO3 ceramics, with different Ho2O3 content, ranging from 0.01 to 1.0 wt% Ho, were investigated regarding their microstructural and dielectric characteristics. The samples were prepared by the conventional solid state reaction and sintered at 1320° and 1380°C in an air atmosphere for 4 hours. The grain size and microstructure characteristics for various samples and their phase composition was carried out using a scanning electron microscope (SEM equipped with EDS system. SEM analysis of Ho/BaTiO3 doped ceramics showed that in samples doped with a rare-earth ions low level, the grain size ranged from 20-30μm, while with the higher dopant concentration the abnormal grain growth is inhibited and the grain size ranged between 2- 10μm. Dielectric measurements were carried out as a function of temperature up to 180°C. The low doped samples sintered at 1380°C, display the high value of dielectric permittivity at room temperature, 2400 for 0.01Ho/BaTiO3. A nearly flat permittivity-response was obtained in specimens with higher additive content. Using a Curie-Weiss low and modified Curie-Weiss low the Curie constant (C, Curie temperature (Tc and a critical exponent of nonlinearity (γ were calculated. The obtained value of γ pointed out that the specimens have almost sharp phase transition.

  11. Gender and marital-history differences in emotional and social loneliness among Dutch older adults.

    In this study, Weiss's (1973) theorizing about the sources of emotional and social loneliness is elaborated--with notions about the asymmetric gratifications derived from marriage, about the conflicting loyalties that result from remarriage, and about selection into marriage--in order to reach an understanding of gender differences in loneliness, both in and outside of marriage. First and subsequent marriages are considered, as well as marital disruptions and never marrying. The data (N = 3737) are from the 1992 Dutch survey on older adults' living arrangements and social networks (NESTOR-LSN). Marital-history differences emerge, not only for emotional loneliness, but also (and contrary to Weiss's theoretical conceptualizations) for social loneliness. The marital-history differences in emotional and social loneliness are greater among men than women. For men, the marriage bond appears not only to be more central to emotional well-being than is the case for women but also to play a pivotal role in their involvement with others. Marital history offers the best explanation for differences in emotional loneliness among men, but social embeddedness characteristics also account for differences in emotional loneliness among women. Apparently, whereas men are more likely to find an intimate attachment in marriage, women also find protection from emotional loneliness in other close ties. The marital-history differences in social loneliness are largely mediated by social embeddedness characteristics, partly in different ways for men and women. Involvement in activities outside the home serves as the context for sociability for men, whereas parenthood plays a more important role in women's social engagements.

  12. Southeast Asian Monsoon variability may have assisted the rise and fall of the Khmer Empire

    Climate shifts with links to human migration and social change have contributed to the global rise and fall of ancient civilizations (Weiss et al 2001; Haug et al. 2003). At the same time, these civilizations also tend to influence their environment significantly (Buckley et. al, 2010). Here we use δ13C and δD data of long-chained n-alkanes to unravel the drivers of monsoon intensity and their potential effects on the Angkor civilization. Strong Sea Surface Temperature (SST) variability from the Indo Pacific Warm Pool (IPWP), coupled to dramatic changes in the Pacific Walker Circulation (PWC) is suggested as a potential driver of the monsoon variability in Southeast Asia over the last two millennia. Our dataset provides independent evidence that past vegetation in Southeast Asia was greatly influenced by the activities of the Angkor people at about AD 834 to 1431 when agricultural activities and extensive hydrological systems may have contributed immensely to change the vegetation type. The massive agricultural boom as a result of increase in monsoon intensity, along with an extensive hydrological system, may have contributed significantly to the rise of the Khmer Empire. However, a prolonged drought as a result of the gradual weakening of the monsoon intensity over time (AD 1375-2000) may have caused the water management system to fail thus contributing significantly to the demise of the Khmer empire.

    The proposed research is a continuation of the work conducted under this contract and is outlined. During this year, the main emphasis will be given to study further the properties of HO/sub 2/ and O/sub 2//sup -/ and OH, mainly in their role in biological systems. We will continue to study and elucidate how O/sub 2//sup -/ reacts in biological systems. The toxicity of O/sub 2//sup -/ is quite well established, but the mechanism is still obscure. The Haber Weiss reaction most probably can not account for the toxicity of O/sub 2//sup -/ nor for the formation of singlet oxygen, nor of OH. We will study if reduction of Fe/sup 3 +/ complexes by O/sub 2//sup -/ in biological systems does catalyze the Haber Weiss reaction and if OH is formed in this mechanism. The role of oxygen, radiosensitizers in radiation damage of bacteriophages and cells will be further studied, as well as on E. Coli and Enzymes. We will try to elucidate the formation and role of OH, O/sub 2//sup -/ and O/sub 2/ in these systems as well as the relative contribution of endogenous and exogenous damage, and the role of direct and indirect radiation damage to cells. We intend also to study if SOD (super oxide dismutase) does react only with O/sub 2//sup -/ or also with biological peroxides (RO/sub 2/) and Hydroperoxides (RO/sub 2/H). Further studies of O/sub 2//sup -/ and O/sub 2/ with various cytochromes, and hemoglobins is planned.

    The synthesis, X-ray crystal structure, and magnetic studies of a rare example of organic/inorganic spin hybrid clusters extended in infinite ladder-type chain [Cu(C5F6HO2)2]7(C35H35N5O4)2 ([Cu(hfac)2]7(pyacbisNN)2, 2) formed by the reaction of a high spin nitronylnitroxide biradical C35H35N5O4 (pyacbisNN, 1) and bis(hexafluroacetylacetonate)copper(II) = Cu(hfac)2 are described. Single-crystal X-ray structure analysis revealed the triclinic P1 space group of 2 with the following parameters: a = 10.6191(4) A, b = 19.6384(7) A, c = 21.941(9) A, alpha = 107.111(7) degrees, beta = 95.107(8) degrees, gamma = 94.208(0) degrees , Z = 2. Each repeating unit in 2 carries a centrosymmetric cyclic six spin and a linear five spin cluster with four different copper coordination environments having octahedral and square planar geometries. These clusters are interconnected to form infinite chains which are running along the crystallographic b axis. The magnetic measurements show nearly paramagnetic behavior with very small variations over a large temperature range. The magnetic properties are thus result of complex competitions of many weak ferro- and antiferromagnetic interactions, which appear as small deviations from quite linear mu(eff) vs T dependence at low temperature. At high temperature (300-14 K), antiferromagnetic behavior dominates a little, while at very low temperature (14-2 K), a small increase of mu(eff) was observed. The magnetic susceptibility data are described by the Curie-Weiss law [chi = C/(T - theta)] with the optimal parameters C = 4.32 +/- 0.01 emuK/mol and theta = - 0.6 +/- 0.3 K, where C is the Curie constant and theta is the Weiss temperature.

    The crystal structure of new hexagonal MgZn2-type {Ho, Tm}FeGa compounds (space group P63/mmc, N 194, hP12) has been established using powder X-ray diffraction studies. The magnetic properties of polycrystalline MgZn2-type ErFeGa compound have been studied using bulk magnetization data. ErFeGa exhibits ferromagnetic ordering at TC = 77 K and field sensitive antiferromagnetic-like ordering at Tm 58 K in field of 100 Oe and Tm 10 K in field of 5 kOe. The paramagnetic susceptibility follows Curie-Weiss law with effective paramagnetic moment per formula unit (Meff/fu) of 9.59 μB and paramagnetic Weiss temperature (ΘP) of 27 K. At 2 K, ErFeGa exhibits hard magnetic properties with remanent magnetization per formula unit (Mres/fu) of 3.7 μB, coercive field (Hcoer) of 8.2 kOe and critical field (Hcrit) of 9.6 kOe. The magnetocaloric effect of ErFeGa has been calculated in terms of isothermal magnetic entropy change (ΔSm) and maximum ΔSm values are -5.5 J/kg K for a field change of 0-50 kOe (relative cooling power RCP50 kOe 410 J/kg), -13.0 J/kg K for a field change of 0-140 kOe (RCP140 kOe 1230 J/kg) at 70 K and +1.7 J/kg K for a field change of 0-10 kOe at 10 K (RCP10 kOe 34 J/kg).

    Recent theoretical and experimental researches have revealed that the strained bulk HgTe can be regarded as a three-dimensional topological insulator (TI). Motivated by this, we explore the strain effects on the transport properties of the HgTe surface states, which are modulated by a weak 1D in-plane electrostatic periodic potential in the presence of a perpendicular magnetic field. We analytically derive the zero frequency (dc) diffusion conductivity for the case of quasielastic scattering in the Kubo formalism, and find that, in strong magnetic field regime, the Shubnikov–de Haas oscillations are superimposed on top of the Weiss oscillations due to the electric modulation for null and finite strain. Furthermore, the strain is shown to remove the degeneracy in inversion symmetric Dirac cones on the top and bottom surfaces. This accordingly gives rise to the splitting and mixture of Landau levels, and the asymmetric spectrum of the dc conductivity. These phenomena, not known in a conventional 2D electron gas and even in a strainless TI and graphene, are a consequence of the anomalous spectrum of surface states in a fully stained TI. These results should be valuable for electronic and spintronic applications of TIs, and thus we fully expect to see them in the further experiment. - Highlights: • The strain removes the degeneracy in inversion symmetric Dirac cones. • The strain gives rise to the splitting and mixture of the Landau levels. • The strain leads to the asymmetric spectrum of the dc conductivity. • Shubnikov de Haas oscillations are shown to be superimposed on Weiss oscillations. • Interplay between strain and electric field causes different occupancy of TI states.

    Highlights: • Magnetic structure is reported from neutron diffraction. • We examine changes of Néel temperature versus V content. • Composition dependence of intra and inter chain exchange parameters are determined. • The temperature dependence of the Mn magnetic moment is determined for MnNb{sub 1.9}V{sub 0.1}O{sub 6}. - Abstract: The structural and magnetic properties of MnNb{sub 2−x}V{sub x}O{sub 6} samples were studied. These materials belong to the AB{sub 2}O{sub 6} class, which presents low-dimensional magnetism. Curie-Weiss fitting gives a negative Weiss temperature that is a characteristic of dominant antiferromagnetic interactions in paramagnetic region. Rietveld refinements of neutron diffraction data show that magnetic moments are aligned antiferromagnetically within the zig-zag chains running along the c axis. Unlike other ANb{sub 2}O{sub 6} type systems crystallizing also in Pbcn space group and presenting ferromagnetic Ising chains, MnNb{sub 2−x}V{sub x}O{sub 6} samples exhibit antiferromagnetic type order along the chains. At 1.5 K, the Mn atoms are found to carry an ordered magnetic moment of about 4.3 μ{sub B}. The Mn chains are antiferromagnetic and do not present significant anisotropy. These characteristics and the high spin allowed us to model the system as weakly interacting classical Heisenberg chains, estimating the values of both intra- and interchain exchange constants evolution with x content.

    The title compound with the nominal formula, Sr{sub 13}Eu{sub 8}Cd{sub 3}Mn{sub 1}Sb{sub 18}, was synthesized by Sn-flux. Structure refinement was based on single-crystal X-ray diffractometer data. Employing the exact composition, the formula is Sr{sub 13.23}Eu{sub 7.77}Cd{sub 3.12}Mn{sub 0.88}Sb{sub 18} for the solid solution Sr{sub 21-x}Eu{sub x}Cd{sub 4-y}Mn{sub y}Sb{sub 18}. This phase adopts the Sr{sub 21}Mn{sub 4}Sb{sub 18} type structure with site preferences for both Eu and Cd. The structure crystallizes in the monoclinic system in space group C2/m and Z=4: a=18.1522(11), b=17.3096(10), c=17.7691(10) Aa, β=91.9638(8) , 6632 F{sup 2} values, 216 variables, R1=0.0254 and wR2=0.0563. Site selectivity of the elements in this new compound will be discussed in relationship with the Sr{sub 21}Mn{sub 4}Sb{sub 18} type structure and other related structure types. Temperature dependent magnetic susceptibility data reveal Curie-Weiss paramagnetism with an experimental moment of 19.3 μ{sub B}/f.u. and a Weiss constant of 0.4 K. Magnetic ordering is seen at low temperatures, with a transition temperature of 3.5 K.
