    2014-01-01

    Werner Albrecht, one of the very first mechanical designers recruited by CERN, passed away on 28 March. Born and educated in Zurich, where he spent the first years of his professional life, he joined CERN in June 1955.   Thanks to his experience and personality, he soon became the deputy to Frank Blythe, the head of the Synchrocyclotron (SC) technical office. The office, which included a large mechanical workshop, had been created in the light of the development and construction of the SC - the first of CERN’s accelerators. For around 25 years Werner kept this position at Frank’s side while the services under their responsibility evolved to become the natural facility to provide design and development for a large range of apparatus required by experimental physicists. After Frank’s retirement in 1980, Werner became head of the office, maintaining its typical character as an efficient, informal and friendly service. Omega, UA1, Aleph, Opal and Delphi are example...

  4. Correlations in Werner States

    2008-01-01

    Werner states are paradigmatic examples of quantum states and play an innovative role in quantum information theory. In investigating the correlating capability of Werner states, we find the curious phenomenon that quantum correlations, as quantified by the entanglement of formation, may exceed the total correlations, as measured by the quantum mutual information. Consequently, though the entanglement of formation is so widely used in quantifying entanglement, it cannot be interpreted as a consistent measure of quantum correlations per se if we accept the folklore that total correlations are measured (or rather upper bounded) by the quantum mutual information.

    2015-09-01

    Full Text Available Werner syndrome (WS is a rare autosomal recessive adult-onset progeroid disorder characterized by the early onset of aged-appearance and age-related metabolic disorders. Symptoms of premature aging usually first develop in the second-third decades of life. We report a 27-year-old female who was admitted to our clinic at the age of eighteen with hyperglycemia. She was diagnosed with diabetes and type 4 dyslipidemia at the age of seven. In her family history, her parents were first cousins and she had three healthy brothers. On her first physical examination; she had bird-like face appearance, global hair loss, beaked nose, short stature and she was overweight. She had global hair loss with gray and thin hair. Hoarseness of voice and hyperkeratosis of skin were observed. She had bilateral cataracts and moderate sensorineural hearing loss. On psychiatric examination, borderline mental retardation was detected. She had severe insulin resistance and hypertriglyceridemia despite levothyroxine, gemfibrozil, omega-3 and intensive insulin treatment. Routine lipid apheresis was performed to lower the triglyceride levels reaching 5256 mg/dL. She also had focal segmental glomerulosclerosis, hepatosteatosis, osteoporosis and epilepsy. Disease was accompanied by several congenital deformities, such as Rathke’s cleft cyst, angiomyolipoma and femoral neck hypoplasia. WS is a rare genetic disorder characterized by multiple endocrine manifestations as well as soft tissue changes. We present a case of early disturbances that were diagnosed before typical clinical signs and symptoms. We propose that WS should be kept in mind when type 2 diabetes and hyperlipidemia are diagnosed early in childhood. Turk Jem 2015; 19: 99-104

    Werner was born in Wiernsheim, a small town in Baden-Württemberg close to Stuttgart. His childhood was profoundly marked by the war and the death of his father on the German eastern front.   Despite life after the war being difficult for his family, he was very successful in his academic studies and earned a fellowship at the University of Göttingen, where he did his PhD in solid-state physics. Werner joined CERN in 1964 as a post-doc fellow and he remained at the Organization for his entire career in experimental particle physics. Concerned and eager for peace in the tense context of the cold war, he was deeply involved in collaboration with Russian colleagues and participated in experiments in Serpukhov from 1968 to 1972. Back at CERN, his work concentrated on the search for experimental evidence of the presence of quarks in hadrons. He was among the main initiators of the NA3 experiment at the SPS that measured the structure functions of the pions: the results indicated a cro...

    Werner Heisenberg was one of the greatest physicists of all times. When he started out as a young research worker, the world of physics was in a very confused and frustrating state, which Abraham Pais has described1 as: It was the spring of hope, it was the winter of despair using Charles Dickens' words in A Tale of Two Cities. People were playing a guessing game: There were from time to time great triumphs in proposing, through sheer intuition, make-shift schemes that amazingly explained some regularities in spectral physics, leading to joy. But invariably such successes would be followed by further work which reveal the inconsistency or inadequacy of the new scheme, leading to despair...

    2005-01-01

    Werner syndrome is a rare autosomal recessive disorder characterized by clinical signs of premature aging, short stature, scleroderma-like skin changes, endocrine abnormalities, cataracts, and an increased incidence of malignancies. We report on a 48-year-old woman with Werner syndrome associated with intracranial meningiomas who had extensive musculoskeletal manifestations including osteoporosis of the extremities, extensive tendinopathy about the ankles, osteomyelitis of the phalanges of the first left toe, abundant soft-tissue calcification, and two dense ossified soft-tissue masses, with cortical bone and trabeculae arising from the posterosuperior aspect of the calcanei and extending into Kager fat pads. A review of previous descriptions of the radiological abnormalities of Werner syndrome indicates that the presence of soft-tissue calcifications has either not been noted or been mentioned only briefly. Moreover, there is no mention of bony masses associated with Werner syndrome in the world literature, and this would appear to be the first report of this kind. (orig.)

    Full Text Available We present applications of the representation theory of Lie groups to the analysis of structure and local unitary classification of Werner states, sometimes called the decoherence-free states, which are states of n quantum bits left unchanged by local transformations that are the same on each particle. We introduce a multiqubit generalization of the singlet state and a construction that assembles these qubits into Werner states.

    2013-02-21

    Neurodegenerative diseases are capturing the world's attention as being the next set of diseases we must tackle collectively. Not only are the patients experiencing gradual cognitive and physical decline in most cases, but these diseases are fatal with no prevention currently available. As these diseases are progressive, providing care and symptom treatment for the ageing population is becoming both a medical and a financial challenge. This review discusses how Werner coordination chemistry plays a role in three diseases - those of Alzheimer's, Parkinson's, and prions. Metal ions are considered to be involved in these diseases in part via their propensity to cause toxic aggregation of proteins. First, the coordination of metal ions, with emphasis on copper(II), to metalloproteins that are hallmarks of these diseases - amyloid β, α-synuclein, and prion, respectively - will be discussed. We will present the current understanding of the metal coordination environments created by the amino acids of these proteins, as well as metal binding affinity. Second, a diverse set of examples of rationally designed metal chelators to outcompete this deleterious binding will be examined based on coordination mode and affinity toward bio-relevant metal ions. Overall, this review will give a general overview of protein and metal chelator coordination environments in neurodegenerative diseases.

    Werner's syndrome is a rare, autosomal recessive inherited disorder with a distinctive clinical picture. The characteristic physiognomy, shortness of stature with thin extremities, and large trophic ulcers are the key signs for the diagnosis. Premature greying of the hair and baldness, juvenile cataracts, a tendency to diabetes mellitus, hypogonadism, calcifications of the blood vessels, osteoporosis, metastatic calcifications of the soft tissue and an elevated incidence of neoplasms are further important features. We describe two patients with this disorder.

    Human fibroblast cells from two different progeroid syndromes, Werner syndrome (WS) and progeria, were established as immortalized cell lines by transfection with plasmid DNA containing the SV40 early region. The lineage of each immortalized cell line was confirmed by VNTR analysis. Each of the immortalized cell lines maintained its original phenotype of slow growth. DNA repair ability of these cells was also studied by measuring sensitivity to killing by uv or the DNA-damaging drugs methyl methansulfonate, bleomycin, and cis-dichlorodiamine platinum. The results showed that both WS and progeria cells have normal sensitivity to these agents

    The eminent Austrian zoologist Franz Werner described several new species of amphibians and reptiles from America, including Anolis aequatorialis Werner, 1894 and Hylodes appendiculatus Werner, 1894. Both species were described based on single specimens, with no more specific type localities than "Ecuador" (Werner 1894a,b). After its description, A. aequatorialis remained unreported until Peters (1967) and Fitch et al. (1976) published information on its distribution and natural history. Anolis aequatorialis is currently known to inhabit low montane and cloud forest on the western slopes of the Andes from extreme southern Colombia to central Ecuador, between 1300 and 2300 m elevation (Ayala-Varela & Velasco 2010; Ayala-Varela et al. 2014; Lynch et al. 2014; D.F. Cisneros-Heredia pers. obs.). Likewise, Hylodes appendiculatus (now Pristimantis appendiculatus) remained only known from its type description until Lynch (1971) and Miyata (1980) provided certain localities and information on its natural history. Pristimantis appendiculatus is currently known to occur in low montane, cloud, and high montane forests on the western slopes of the Andes from extreme southern Colombia to northern Ecuador between 1460 and 2800 m elevation (Lynch 1971; Miyata 1980; Lynch & Burrowes 1990; Lynch & Duellman 1997; Frost 2016). To this date, the type localities of both species remain obscure. The purpose of this paper is to restrict the type localities of Hylodes appendiculatus Werner, 1894 and Anolis aequatorialis Werner, 1894 based on analyses of the travel journals of their original collector.

  3. Accelerated epigenetic aging in Werner syndrome.

    Individuals suffering from Werner syndrome (WS) exhibit many clinical signs of accelerated aging. While the underlying constitutional mutation leads to accelerated rates of DNA damage, it is not yet known whether WS is also associated with an increased epigenetic age according to a DNA methylation based biomarker of aging (the "Epigenetic Clock"). Using whole blood methylation data from 18 WS cases and 18 age matched controls, we find that WS is associated with increased extrinsic epigenetic age acceleration (p=0.0072) and intrinsic epigenetic age acceleration (p=0.04), the latter of which is independent of age-related changes in the composition of peripheral blood cells. A multivariate model analysis reveals that WS is associated with an increase in DNA methylation age (on average 6.4 years, p=0.011) even after adjusting for chronological age, gender, and blood cell counts. Further, WS might be associated with a reduction in naïve CD8+ T cells (p=0.025) according to imputed measures of blood cell counts. Overall, this study shows that WS is associated with an increased epigenetic age of blood cells which is independent of changes in blood cell composition. The extent to which this alteration is a cause or effect of WS disease phenotypes remains unknown.

  4. The Werner gap in the presence of simple coloured noise

    Science.gov (United States)

    Cong Tran, Minh; Laskowski, Wiesław; Paterek, Tomasz

    2014-10-01

    The ‘Werner gap’ is the range of relevant parameters characterizing a quantum state for which it is both entangled and admits a local hidden variable model. Werner showed that the gap becomes maximal for entanglement mixed with white noise if subsystems have infinitely many levels. Here we study pure entangled states mixed with simple coloured noise modelled as a single pure product state. We provide an explicit local hidden variable model for quantum correlations of some states of this family and provide hints that there is probably a model for all quantum predictions. This demonstrates essentially a maximal Werner gap already for just two qubits. Additionally to its fundamental interest, the study has implications for quantum computation and communication. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘50 years of Bell’s theorem’.

  5. Adaptive estimation and discrimination of Holevo-Werner channels

    Cope Thomas P. W.

    2017-12-01

    Full Text Available The class of quantum states known as Werner states have several interesting properties, which often serve to illuminate unusual properties of quantum information. Closely related to these states are the Holevo- Werner channels whose Choi matrices are Werner states. Exploiting the fact that these channels are teleportation covariant, and therefore simulable by teleportation, we compute the ultimate precision in the adaptive estimation of their channel-defining parameter. Similarly, we bound the minimum error probability affecting the adaptive discrimination of any two of these channels. In this case, we prove an analytical formula for the quantum Chernoff bound which also has a direct counterpart for the class of depolarizing channels. Our work exploits previous methods established in [Pirandola and Lupo, PRL 118, 100502 (2017] to set the metrological limits associated with this interesting class of quantum channels at any finite dimension.

    Werner syndrome protein (WRN) is one of a family of five human RecQ helicases implicated in the maintenance of genome stability. The conserved RecQ family also includes RecQ1, Bloom syndrome protein (BLM), RecQ4, and RecQ5 in humans, as well as Sgs1 in Saccharomyces cerevisiae, Rqh1...... in Schizosaccharomyces pombe, and homologs in Caenorhabditis elegans, Xenopus laevis, and Drosophila melanogaster. Defects in three of the RecQ helicases, RecQ4, BLM, and WRN, cause human pathologies linked with cancer predisposition and premature aging. Mutations in the WRN gene are the causative factor of Werner...

    Lessel, D.; Oshima, J.; Kubisch, C.

    2013-01-01

    Das Werner-Syndrom ist eine segmental progeroide Erkrankung mit Beginn in der Adoleszenz oder im frühen Erwachsenenalter. Typische Symptome, die zum vorgealterten Phänotyp beitragen, sind ein post-pubertär auftretender Kleinwuchs, Katarakte, eine vorzeitige Ergrauung/Ausdünnung des Haupthaars, sklerodermieähnliche Hautveränderungen und eine regionale Atrophie des subkutanen Fettgewebes. Darüber hinaus kommt es früh und gehäuft zu „Alterserkrankungen“ wie z. B. einem Diabetes mellitus Typ 2, einer Osteoporose, einer Atherosklerose sowie verschiedenen malignen Tumoren. Das Werner-Syndrom wird autosomal- rezessiv vererbt und ist durch Mutationen im Werner-Gen (WRN) bedingt. Es wurden bis heute mehr als 70 über das gesamte Gen verteilte Mutationen identifiziert, die typischerweise zu einem Verlust der Genfunktion führen. WRN kodiert für eine RecQ-Typ- Helikase, die u. a. an der DNA-Reparatur und der Aufrechterhaltung der DNA-Integrität beteiligt ist, was sich in einer erhöhten genetischen Instabilität in Patientenzellen wider-spiegelt. Trotz der relativen Seltenheit ist die Analyse des Werner-Syndroms von allgemeiner Bedeutung, um die Rolle der DNA-Stabilität und Integrität für das Altern sowie die Entwicklung altersassoziierter Erkrankungen besser zu verstehen.

    Werner syndrome is a premature aging disease characterized by genomic instability and increased cancer risk. Here, we report a 45-year-old diabetic man as the first Werner syndrome patient found to have an adiponectin gene mutation. Showing graying and loss of hair, skin atrophy, and juvenile cataract, he was diagnosed with Werner syndrome type 4 by molecular analysis. His serum adiponectin concentration was low. In the globular domain of the adiponectin gene, I164T in exon 3 was detected. When we examined effects of pioglitazone (15 mg/day) on serum adiponectin multimer and monomer concentrations using selective assays, the patient's relative percentage increased in adiponectin concentration was almost same as that in the 18 diabetic patients without an adiponectin mutation, but the absolute adiponectin concentration was half of those seen in diabetic patients treated with the same pioglitazone dose who had no adiponectin mutation. The response suggested that pioglitazone treatment might help to prevent future Werner syndrome-related acceleration of atherosclerosis. Present and further clinical relevant to atherosclerosis in this patient should be imformative concerning the pathogenesis and treatment of atherosclerosis in the presence of hypoadiponectinemia and insulin resistance.

    We described a case of Werner's syndrome associated with osteosarcoma. A 37-year-old Japanese man was diagnosed as having Werner's syndrome by the presence of juvenile cataracts, skin sclerosis and hyperpigmentation of the feet, high-pitched voice, characteristic bird-like appearance of the face with beak-shaped nose, thinning of the entire skin and hyperkeratoses on soles, hyperlipemia, hyperuricemia, diabetes melitus, and the mutated responsible gene (WRN). He had a 3-month history of a tumor on his left forearm. Histologically, the tumor included four histological patterns; a malignant fibrous histiocytoma-like, a desmoid-like, a dermatofibrosarcoma protuberans-like, and a chondrosarcoma-like pattern. Tumoral osteoid formation was also found in the tumor. Therefore, the tumor was diagnosed as osteosarcoma.

  11. Compatible quantum correlations: Extension problems for Werner and isotropic states

    Science.gov (United States)

    Johnson, Peter D.; Viola, Lorenza

    2013-09-01

    We investigate some basic scenarios in which a given set of bipartite quantum states may consistently arise as the set of reduced states of a global N-partite quantum state. Intuitively, we say that the multipartite state “joins” the underlying correlations. Determining whether, for a given set of states and a given joining structure, a compatible N-partite quantum state exists is known as the quantum marginal problem. We restrict to bipartite reduced states that belong to the paradigmatic classes of Werner and isotropic states in d dimensions and focus on two specific versions of the quantum marginal problem which we find to be tractable. The first is Alice-Bob, Alice-Charlie joining, with both pairs being in a Werner or isotropic state. The second is m-n sharability of a Werner state across N subsystems, which may be seen as a variant of the N-representability problem to the case where subsystems are partitioned into two groupings of m and n parties, respectively. By exploiting the symmetry properties that each class of states enjoys, we determine necessary and sufficient conditions for three-party joinability and 1-n sharability for arbitrary d. Our results explicitly show that although entanglement is required for sharing limitations to emerge, correlations beyond entanglement generally suffice to restrict joinability, and not all unentangled states necessarily obey the same limitations. The relationship between joinability and quantum cloning as well as implications for the joinability of arbitrary bipartite states are discussed.

    The psychiatrist and medical historian Werner Leibbrand resigned from the Berlin Medical Association after the seizure of power in protest against the exclusion of Jewish colleagues and lost both the license to practice as well as his professional position in the public health service. After the end of the war the American military authorities appointed him as expert witness for the prosecution in the Nürnberg Doctors Trial. In addition to a biographical review, Leibbrand's resolute although still undisputed attitude as ethical expert in the trials will be roughly outlined.

    Full Text Available Herlyn-Werner-Wunderlich syndrome (HWW is a triad of didelphys uterus, obstructed hemivagina, and ipsilateral renal agenesis. It is a combined anomaly of Mullerian and mesonephric ducts. It usually presents in adolescent females after menarche with nonspecific symptoms of pelvic pain, dysmenorrhea, and rarely a palpable pelvic mass. We report here, a case of an 18-year-old female presenting with complaints of lower abdominal pain and dysmenorrhea where magnetic resonance imaging (MRI confirmed the diagnosis of HWW syndrome. MRI is the imaging modality of choice for diagnosis of HWW syndrome and associated complications such as endometriosis.

    Full Text Available Busch, Lahti and Werner (BLW have recently criticized the operator approach to the description of quantum errors and disturbances. Their criticisms are justified to the extent that the physical meaning of the operator definitions has not hitherto been adequately explained. We rectify that omission. We then examine BLW’s criticisms in the light of our analysis. We argue that, although the BLW approach favour (based on the Wasserstein two-deviation has its uses, there are important physical situations where an operator approach is preferable. We also discuss the reason why the error-disturbance relation is still giving rise to controversies almost a century after Heisenberg first stated his microscope argument. We argue that the source of the difficulties is the problem of interpretation, which is not so wholly disconnected from experimental practicalities as is sometimes supposed.

    To investigate the clinical characteristics and treatment of the Herlyn-Werner-Wunderlich syndrome (HWWS). Sixty-one patients diagnosed with HWWS were retrospectively analyzed. HWWS is categorized into three types in China. Age at presentation of all the cases was after menarche. The most common clinical presentations were dysmenorrhea for type I and vaginal discharge for types II and III. Clinical presentations of types II and III may not occur until reproductive age. HWWS occurred on the right in 39/61. Excision of the obstructed vaginal septum was the treatment utilized in this cohort. After surgery, subsequent pregnancies were ipsilateral in 52.9 %. Clinical presentation in untreated HWWS suggests the anatomic anomaly. Early recognition and treatment can reduce symptoms. Pregnancies occur in both the affected and unaffected uterus.

  19. Stochastic simulations of normal aging and Werner's syndrome.

    Human cells typically consist of 23 pairs of chromosomes. Telomeres are repetitive sequences of DNA located at the ends of chromosomes. During cell replication, a number of basepairs are lost from the end of the chromosome and this shortening restricts the number of divisions that a cell can complete before it becomes senescent, or non-replicative. In this paper, we use Monte Carlo simulations to form a stochastic model of telomere shortening to investigate how telomere shortening affects normal aging. Using this model, we study various hypotheses for the way in which shortening occurs by comparing their impact on aging at the chromosome and cell levels. We consider different types of length-dependent loss and replication probabilities to describe these processes. After analyzing a simple model for a population of independent chromosomes, we simulate a population of cells in which each cell has 46 chromosomes and the shortest telomere governs the replicative potential of the cell. We generalize these simulations to Werner\\'s syndrome, a condition in which large sections of DNA are removed during cell division and, amongst other conditions, results in rapid aging. Since the mechanisms governing the loss of additional basepairs are not known, we use our model to simulate a variety of possible forms for the rate at which additional telomeres are lost per replication and several expressions for how the probability of cell division depends on telomere length. As well as the evolution of the mean telomere length, we consider the standard deviation and the shape of the distribution. We compare our results with a variety of data from the literature, covering both experimental data and previous models. We find good agreement for the evolution of telomere length when plotted against population doubling.

  20. Use of p38 MAPK Inhibitors for the Treatment of Werner Syndrome

    2010-06-01

    Full Text Available Werner syndrome provides a convincing model for aspects of the normal ageing phenotype and may provide a suitable model for therapeutic interventions designed to combat the ageing process. Cultured primary fibroblast cells from Werner syndrome patients provide a powerful model system to study the link between replicative senescence in vitro and in vivo pathophysiology. Genome instability, together with an increased pro-oxidant state, and frequent replication fork stalling, all provide plausible triggers for intracellular stress in Werner syndrome cells, and implicates p38 MAPK signaling in their shortened replicative lifespan. A number of different p38 MAPK inhibitor chemotypes have been prepared rapidly and efficiently using microwave heating techniques for biological study in Werner syndrome cells, including SB203580, VX-745, RO3201195, UR-13756 and BIRB 796, and their selectivity and potency evaluated in this cellular context. Werner syndrome fibroblasts treated with a p38 MAPK inhibitor reveal an unexpected reversal of the accelerated ageing phenotype. Thus the study of p38 inhibition and its effect upon Werner pathophysiology is likely to provide new revelations into the biological mechanisms operating in cellular senescence and human ageing in the future.

  1. [The birth of acknowledgement: Michel Foucault and Werner Leibbrand].

    Mildenberger, Florian

    2006-01-01

    In 1964, Werner Leibbrand (1896-1974) was the first German medical historian to present, in Sudhoffs Archiv, a review of the work of Michel Foucault (1926-1984). This paper examines some of the reasons leading to the fact that Leibbrand's own generation refused to acknowledge the importance of Foucault's ideas, while, later on, younger German medical historians, although impressed with Foucault's writings, failed to acknowledge, first, the close relationship between Leibbrand's and Foucault's world views, and, second, Leibbrand's attempts at introducing Foucault to German medical historians. Leibbrand with his Jewish wife had survived the Nazi period partly in hiding. His attempts at clearing post-war German psychiatry and medical historiography of NS-sympathizers isolated him among his colleagues, many of whom had begun their career during the Third Reich. Leibbrand enjoyed the support by the Swiss medical historian and avowed Communist Erwin Ackerknecht (1906-1988), but later turned against him, possibly because Acknerknecht had called Leibbrand's writings "unscientific". Leibbrand was unable to overcome his antagonisms with his contemporaries. At the same time, opposition to Ackerknecht made him appear a respresentative of the past in the eyes of the younger generation. Thus, when Foucault was accepted by the latter, they were not prepared to examine the work of Leibbrand and realize how close some of the ideas developed by Leibbrand and Foucault had been.

    Werner syndrome (WS; MIM#277700) or adult progeria, is a rare disease, associated with mutations of a single gene (RECQL2 or WRN), located on chromosome 8 (8p12). It codes a DNA-helicase, whose defects cause genomic instability. The highest incidences are reported in Japan and Sardinia (Italy). On this major island of the Mediterranean Basin, the WS cases have been observed in the northern areas. The authors describe the apparently first case reported in southern Sardinia, a 51-year-old woman, who was born in and resides in the province of Cagliari. She presented with a 9-year history of an intractable leg ulcer and other characteristic symptoms, including "bird-like" face, high-pitched voice, premature greying, short stature, abdominal obesity in contrast with thin body type, scleroderma-like legs, decreased muscle mass, diabetes, atherosclerosis, and premature menopause. A specialized genetic Institute of Research (IRCCS-IDI, Rome) confirmed the clinical diagnosis. There is no cure or specific treatment and patients must be periodically screened for an increased risk of cardiovascular and cerebrovascular disease and malignancies. Among the many findings, leg ulcers significantly affect the patient's quality of life. This problem may send the patient to the dermatologist, who finally suspects the diagnosis. Poor response to medical treatment may require aggressive repeated surgery, with poor or temporary results.

    2014-01-01

    The development of organic and physical chemistry as specialist fields, during the middle and end of the 19th century respectively, left inorganic behind as a decidedly less highly regarded subfield of chemistry. Despite Alfred Werner's groundbreaking studies of coordination chemistry in the early 20th century, that inferior status remained in place - particularly in the US - until the 1950s, when the beginnings of a resurgence that eventually restored its parity with the other subfields can be clearly observed. This paper explores the extent to which Werner's heritage - both direct, in the form of academic descendants, and indirect - contributed to those advances.

  9. Heinz Werner: His Life, Ideas, and Contributions to Developmental Psychology in the First Half of the 20th Century.

    Ostler, Teresa

    2016-01-01

    The author provides an overview of Heinz Werner's life and contributions to the field of developmental psychology during the first half of the 20th century. She focuses on his early work in Vienna and Munich as well as his tenure at the Psychological Institute in Hamburg, up through the time when he became a named Professor in Psychology at Clark University. Recognized as one of the founders of developmental psychology, Heinz Werner worked in the areas of perceptual development, comparative psychology, and symbol formation. Versatile in rigorous experimental methodologies, and in observational and phenomenological methodologies, Werner's approach to development stood in contrast to other approaches of development, both past and current. For Werner, development was a heuristic, a way of looking at processes in a variety of domains, including ontogeny, phylogeny, microgenesis, biology, developmental psychopathology, neuropsychology, and comparative psychology. Werner viewed development as proceeding from a state of relative globality and lack of differentiation to a state of increasing differentiation, articulation, and hierarchical integration, but he also stressed that individuals can function at different developmental levels under different times and conditions. Werner's holistic, organismic, comparative, and contextual approach to development transcended interdisciplinary boundaries, allowing him to study the interrelatedness between thought, language, feeling, perception, and culture.

    This paper follows Werner Heisenberg and Carl Friedrich von Weizsäcker during their fifty-year friendship from 1926, when they first met in Copenhagen, to Heisenberg's death in Munich in 1976. The relationship underwent profound changes during that period, as did physics, philosophy, and German society and politics, all of which exerted important influences on their lives, work, and interactions with each other. The nature of these developments and their impact are explored in this paper.

    Supermassive stars born in pristine environments in the early Universe hold the promise of being the seeds for the supermassive black holes observed as high redshift quasars shortly after the epoch of reionisation. {H_2} suppression is thought to be crucial in order to negate normal Population III star formation and allow high accretion rates to drive the formation of supermassive stars. Only in the cases where vigorous fragmentation is avoided will a monolithic collapse be successful giving rise to a single massive central object. We investigate the number of fragmentation sites formed in collapsing atomic cooling haloes subject to various levels of background Lyman-Werner flux. The background Lyman-Werner flux manipulates the chemical properties of the gas in the collapsing halo by destroying {H_2}. We find that only when the collapsing gas cloud shifts from the molecular to the atomic cooling regime is the degree of fragmentation suppressed. In our particular case we find that this occurs above a critical Lyman-Werner background of J ˜ 10 J21. The important criterion being the transition to the atomic cooling regime rather than the actual value of J, which will vary locally. Once the temperature of the gas exceeds T ≳ 104 K and the gas transitions to atomic line cooling, then vigorous fragmentation is strongly suppressed.

    2017-04-01

    Disentanglement and loss of quantum correlations due to one global collective noise effect are described for two-qubit Schrödinger cat and Werner states of a four level trapped ion quantum system. Once the Jaynes-Cummings ionic interactions are mapped onto a Dirac spinor structure, the elementary tools for computing quantum correlations of two-qubit ionic states are provided. With two-qubit quantum numbers related to the total angular momentum and to its projection onto the direction of an external magnetic field (which lifts the degeneracy of the ion’s internal levels), a complete analytical profile of entanglement for the Schrödinger cat and Werner states is obtained. Under vacuum noise (during spontaneous emission), the two-qubit entanglement in the Schrödinger cat states is shown to vanish asymptotically. Otherwise, the robustness of Werner states is concomitantly identified, with the entanglement content recovered by their noiseless-like evolution. Most importantly, our results point to a firstly reported sudden transition between classical and quantum decay regimes driven by a classical collective noise on the Schrödinger cat states, which has been quantified by the geometric discord.

    In 1956, the Nobel Prize in Physiology or Medicine was awarded jointly to Werner Forssmann, André Frédéric Cournand and Dickinson W. Richards for their development of cardiac catheterization. Forssmann performed a self-experiment in 1929 by inserting a urethral catheter into his right ventricular cavity via his antecubital vein. Despite his popularity as one of the first German Nobel Laureates after 1945, little is known about Forssmann personally. This contribution aims to close this gap regarding the Nazi period and early post-war Germany. Primary historical sources from Forssmann's private archive were examined, evaluated and interpreted for the first time. Additionally, a comparative analysis based on further archival and secondary sources was performed. Werner Forssmann joined the Nazi Party, the Sturmabteilung (Stormtroopers, SA) and the Nationalsozialistischer Deutscher Ärztebund (Nazi Doctors' Association) in 1932, a year before Hitler's assumption of power. In his autobiography, Forssmann referred to the political situation in passing. However, he expressed his personal thoughts in private letters which he wrote as a medical officer during the war. After World War II, Forssmann underwent denazification and was banned from practicing medicine for 3 years. He did not seem to be averse to Hitler's politics and in some ways expressed his approval. However, correspondence from the 1960s with 2 Jewish colleagues reveals that Forssmann may have changed his attitude toward National Socialism later. Werner Forssmann's political attitudes during the Third Reich and in the post-war era can be characterized as early agreement that gradually changed to a more critical distance to Nazi ideology. In this respect, Forssmann appears to be quite a typical example of a larger proportion of German medical doctors during these eras. © 2016 S. Karger AG, Basel.

    Full Text Available The article aims at showing how complex can be the relationship between literary prototype and operatic work. It analyses the adaptation of Heinrich von Kleist’s drama by two outstanding postwar artists: the Austrian author Ingeborg Bachmann (1926–1973 and the German composer Hans Werner Henze (1926–2012. They not only adjust the dramatic text to the needs of the operatic medium. They also, very much in the spirit of their times (1958, try to rethink, to “save” as they put it, a work of art misused by the ideology of Wilhelminism and the Third Reich. In their interpretation they turn their back on military and political content of the drama, focus their attention on the person of the Prince, glorifying him as a dreamer and outsider.

    Il genio di Werner Heisenberg attraversa l'orizzonte della fisica del nostro secolo come una meteora. Testimoniano della fecondità e dell'originalità del suo pensiero non solo il Nobel che gli fu assegnato a soli 32 anni, ma soprattutto i decisivi impulsi da lui dati alla fisica quantistica, alla teoria delle particelle elementari, alla teoria del nucleo. Si deve a Heisenberg quel "principio di indeterminazione" che ha rivoluzionato non solo il corso della fisica ma il modo di concepire la posizione dell'uomo nell'universo. L'interesse del libro, però, vuole andare oltre la fisica, giacché il curriculum del "ragazzo di campagna dei biondi capelli" rispecchia in forma emblematica l'ambiguo rapporto della scienza col potere.

    Full Text Available Abstract: Werner Syndrome (WS is a premature aging disease that begins in adolescence or early adulthood and results in the appearance of old age by 30-40 years of age. Some endocrinological abnormalities were manifested in this rare disease, such as hypogonadism, diabetes mellitus, hyperlipidemia. In this article, we present a nineteen years-old female patient who had been diagnosed as WS two years ago because of type 2 diabetes mellitus, osteopenia, hyperlipidemia, cataract, gray hair, and skin atrophy. Subclinical hypothyroidism was detected at her laboratory tests. Thyroid ultrasonography (USG showed thyroid atrophy. Fine needle aspiration biopsy of both lobes confirmed this diagnose and excluded some infiltrative diseases such as amyloidosis. It should be kept in mind that thyroid atrophy could be seen in WS and, therefore, detailed thyroid examination including thyroid USG and close follow up should be performed in all patients with WS.

We present a rare and unusual case of this syndrome in a 19 year-old female who suffered from hypomenorrhoea and abdominal pain. She had an obstructed hemi-vagina on right side which led to marked distention of ipsilateral cervix, while proximal hemi-vagina compressed the contralateral side causing its partial obstruction resulting in hypomenorrhoea. Understanding the imaging findings of this rare condition is important for early diagnosis in order to prevent complications which may lead to infertility.

    Herlyn-Werner-Wunderlich (HWW) syndrome is a rare müllerian duct anomaly with uterus didelphys, unilateral obstructed hemivagina, and ipsilateral renal agenesis. Patients with this syndrome generally present after menarche with pelvic pain and mass and, rarely, primary infertility in later years. Strong suspicion and knowledge of this syndrome are mandatory for an accurate diagnosis. A 14-year-old female patient presented with acute retention of urine and abdominopelvic pain. Her condition was diagnosed with the use ultrasonography and magnetic resonance imaging as a case of HWW syndrome. She was treated with vaginal hemiseptal resection. The HWW syndrome should be considered among the differential diagnoses in girls with renal anomalies presenting with pelvic mass, symptoms of acute abdominal pain, and acute urinary retention.

Nowadays, at least 90% of the 93 listed species are threatened and more than 77% are Critically Endangered (McCaffery et al. 2015; IUCN 2016). Colombia has 44 described species of Atelopus (Frost 2017), two of these are categorized as extinct (EX) by the IUCN (2016): A. ignescens and A. longirostris, although they were recently re-discovered in Ecuador (Tapia et al. 2017), 34 as critical endangered (CR), four as endangered (EN), two as vulnerable (VU), one species has data deficient (DD) and another one has not been evaluated. Atelopus subornatus Werner, 1899, is an endemic Colombian harlequin toad described from 2300 to 2800 m.a.s.l in the municipalities of Sibaté (Alto de Sibaté and Agua Bonita) and Fusagasuga (above Fusagasuga and Tierra Negra), in Cundinamarca (Fig. 1A), on the western flank from Cordillera Oriental of Colombia (Werner 1899; Lynch 1986; Lötters 1989, 1992). The last record of this species was in 1993 (Lötters 2005), and it currently is listed as Critically Endangered by the IUCN (2016). Herein, we report the rediscovery of A. subornatus at a new locality from Tolima, Colombia (Fig. 1A), and redescribe its tadpole. The determination of the species was based on comparisons with material deposited in the amphibian collection of the Instituto de Ciencias Naturales, Universidad Nacional de Colombia (ICN-UNAL) for all species of Atelopus reported from the same general area in Cundinamarca and relatively similar to A. subornatus. The specimens are housed in the Herpetological collection of the Tolima University (CZUT-A) and amphibian collection of ICN-UNAL.

  5. Genetics and aging; the Werner syndrome as a segmental progeroid syndrome.

    The maximum lifespan potential is a constitutional feature of speciation and must be subject to polygenic controls acting both in the domain of development and in the domain of the maintenance of macromolecular integrity. The enormous genetic heterogeneity that characterizes our own species, the complexities of numerous nature-nurture interactions, and the quantitative and qualitative variations of the senescent phenotype that are observed suggest that precise patterns of aging in each of us may be unique. Patterns of aging may also differ sharply among species (for example, semelparous vs. multiparous mammals). Some potential common denominators, however, allow one to identify progeroid syndromes in man that could lead to the elucidation of important pathways of gene action. (The suffix "-oid" means "like"; it does not mean identity.) Unimodal progeroid syndromes (eg., familial dementia of the Alzheimer type, an autosomal dominant) can help us understand the pathogenesis of a particular aspect of the senescent phenotype of man. Segmental progeroid syndromes (eg. the Werner syndrome, an autosomal recessive) may be relevant to multiple aspects of the senescent phenotype. Some results of research on the Werner syndrome may be interpreted as support for "peripheral" as opposed to "central" theories of aging; they are consistent with the view that gene action in the domain of development (adolescence, in this instance) can set the stage for patterns of aging in the adult; they point to the importance of mesenchymal cell populations in the pathogenesis of age-related disorders; finally, they underscore the role of chromosomal instability, especially in the pathogenesis of neoplasia.

    Luminous quasars detected at redshifts z > 6 require that the first black holes form early and grow to ~109 solar masses within one Gyr. Our work uses cosmological simulations to study the formation and early growth of direct collapse black holes. In the pre-reionization epoch, molecular hydrogen (H2) causes gas to fragment and form Population III stars, but Lyman-Werner radiation can suppress H2 formation and allow gas to collapse directly into a massive black hole. The critical flux required to inhibit H2 formation, Jcrit, is hotly debated, largely due to the uncertainties in the source radiation spectrum, H2 self-shielding, and collisional dissociation rates. Here, we test the power of the direct collapse model in a non-uniform Lyman-Werner radiation field, using an updated version of the SPH+N-body tree code Gasoline with H2 non-equilibrium abundance tracking, H2 cooling, and a modern SPH implementation. We vary Jcrit from 30 to 104 J21 to study the effect on seed black holes, focusing on black hole formation as a function of environment, halo mass, metallicity, and proximity of the Lyman-Werner source. We discuss the constraints on massive black hole occupation fraction in the quasar epoch, and implications for reionization, high-redshift X-ray background radiation, and gravitational waves.

    Full Text Available Purpose. To examine the promoter methylation and histone modification of WRN (Werner syndrome gene, a DNA repair gene, and their relationship with the gene expression in age-related cataract (ARC lens. Methods. We collected the lenses after cataract surgery from 117ARC patients and 39 age-matched non-ARC. WRN expression, DNA methylation and histone modification around the CpG island were assessed. The methylation status of Human-lens-epithelium cell (HLEB-3 was chemically altered to observe the relationship between methylation and expression of WRN. Results. The WRN expression was significantly decreased in the ARC anterior lens capsules comparing with the control. The CpG island of WRN promoter in the ARC anterior lens capsules displayed hypermethylation comparing with the controls. The WRN promoter was almost fully methylated in the cortex of ARC and control lens. Acetylated H3 was lower while methylated H3-K9 was higher in ARC anterior lens capsules than that of the controls. The expression of WRN in HLEB-3 increased after demethylation of the cells. Conclusions. A hypermethylation in WRN promoter and altered histone modification in anterior lens capsules might contribute to the ARC mechanism. The data suggest an association of altered DNA repair capability in lens with ARC pathogenesis.

    Full Text Available Werner syndrome (WS patients exhibit premature aging predominantly in mesenchyme-derived tissues, but not in neural lineages, a consequence of telomere dysfunction and accelerated senescence. The cause of this lineage-specific aging remains unknown. Here, we document that reprogramming of WS fibroblasts to pluripotency elongated telomere length and prevented telomere dysfunction. To obtain mechanistic insight into the origin of tissue-specific aging, we differentiated iPSCs to mesenchymal stem cells (MSCs and neural stem/progenitor cells (NPCs. We observed recurrence of premature senescence associated with accelerated telomere attrition and defective synthesis of the lagging strand telomeres in MSCs, but not in NPCs. We postulate this “aging” discrepancy is regulated by telomerase. Expression of hTERT or p53 knockdown ameliorated the accelerated aging phenotypein MSC, whereas inhibition of telomerase sensitized NPCs to DNA damage. Our findings unveil a role for telomerase in the protection of accelerated aging in a specific lineage of stem cells.

    Full Text Available Aging, the universal phenomenon, affects human health and is the primary risk factor for major disease pathologies. Progeroid diseases, which mimic aging at an accelerated rate, have provided cues in understanding the hallmarks of aging. Mutations in DNA repair genes as well as in telomerase subunits are known to cause progeroid syndromes. Werner syndrome (WS, which is characterized by accelerated aging, is an autosomal-recessive genetic disorder. Hallmarks that define the aging process include genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulation of nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and altered intercellular communication. WS recapitulates these hallmarks of aging and shows increased incidence and early onset of specific cancers. Genome integrity and stability ensure the normal functioning of the cell and are mainly guarded by the DNA repair machinery and telomeres. WRN, being a RecQ helicase, protects genome stability by regulating DNA repair pathways and telomeres. Recent advances in WS research have elucidated WRN’s role in DNA repair pathway choice regulation, telomere maintenance, resolution of complex DNA structures, epigenetic regulation, and stem cell maintenance.

  12. Frequency of Werner helicase 1367 polymorphism and age-related morbidity in an elderly Brazilian population

    2005-07-01

    Full Text Available Werner syndrome (WS is a premature aging disease caused by a mutation in the WRN gene. The gene was identified in 1996 and its product acts as a DNA helicase and exonuclease. Some specific WRN polymorphic variants were associated with increased risk for cardiovascular diseases. The identification of genetic polymorphisms as risk factors for complex diseases affecting older people can improve their prevention, diagnosis and prognosis. We investigated WRN codon 1367 polymorphism in 383 residents in a district of the city of São Paulo, who were enrolled in an Elderly Brazilian Longitudinal Study. Their mean age was 79.70 ± 5.32 years, ranging from 67 to 97. This population was composed of 262 females (68.4% and 121 males (31.6% of European (89.2%, Japanese (3.3%, Middle Eastern (1.81%, and mixed and/or other origins (5.7%. There are no studies concerning this polymorphism in Brazilian population. These subjects were evaluated clinically every two years. The major health problems and morbidities affecting this cohort were cardiovascular diseases (21.7%, hypertension (83.7%, diabetes (63.3%, obesity (41.23%, dementia (8.0%, depression (20.0%, and neoplasia (10.8%. Their prevalence is similar to some urban elderly Brazilian samples. DNA was isolated from blood cells, amplified by PCR and digested with PmaCI. Allele frequencies were 0.788 for the cysteine and 0.211 for the arginine. Genotype distributions were within that expected for the Hardy-Weinberg equilibrium. Female gender was associated with hypertension and obesity. Logistic regression analysis did not detect significant association between the polymorphism and morbidity. These findings confirm those from Europeans and differ from Japanese population.

    Genetic diagnosis of inherited metabolic disease is conventionally achieved through syndrome recognition and targeted gene sequencing, but many patients receive no specific diagnosis. Next-generation sequencing allied to capture of expressed sequences from genomic DNA now offers a powerful new diagnostic approach. Barriers to routine diagnostic use include cost, and the complexity of interpreting results arising from simultaneous identification of large numbers of variants. We applied exome-wide sequencing to an individual, 16-year-old daughter of consanguineous parents with a novel syndrome of short stature, severe insulin resistance, ptosis, and microcephaly. Pulldown of expressed sequences from genomic DNA followed by massively parallel sequencing was undertaken. Single nucleotide variants were called using SAMtools prior to filtering based on sequence quality and existence in control genomes and exomes. Of 485 genetic variants predicted to alter protein sequence and absent from control data, 24 were homozygous in the patient. One mutation – the p.Arg732X mutation in the WRN gene – has previously been reported in Werner's syndrome (WS). On re-evaluation of the patient several early features of WS were detected including loss of fat from the extremities and frontal hair thinning. Lymphoblastoid cells from the proband exhibited a defective decatenation checkpoint, consistent with loss of WRN activity. We have thus diagnosed WS some 15 years earlier than average, permitting aggressive prophylactic therapy and screening for WS complications, illustrating the potential of exome-wide sequencing to achieve early diagnosis and change management of rare autosomal recessive disease, even in individual patients of consanguineous parentage with apparently novel syndromes.

    Reactive oxygen species constantly generated as by-products of cellular metabolism readily attack genomic DNA creating mutagenic lesions such as 7,8-dihydro-8-oxo-guanine (8-oxo-G) that promote aging. 8-oxo-G:A mispairs arising during DNA replication are eliminated by base excision repair initiated by the MutY DNA glycosylase homologue (MUTYH). Here, by using formaldehyde crosslinking in mammalian cell extracts, we demonstrate that the WRN helicase/exonuclease defective in the premature aging disorder Werner syndrome (WS) is recruited to DNA duplex containing an 8-oxo-G:A mispair in a manner dependent on DNA polymerase λ (Polλ) that catalyzes accurate DNA synthesis over 8-oxo-G. Similarly, by immunofluorescence, we show that Polλ is required for accumulation of WRN at sites of 8-oxo-G lesions in human cells. Moreover, we show that nuclear focus formation of WRN and Polλ induced by oxidative stress is dependent on ongoing DNA replication and on the presence of MUTYH. Cell viability assays reveal that depletion of MUTYH suppresses the hypersensitivity of cells lacking WRN and/or Polλ to oxidative stress. Biochemical studies demonstrate that WRN binds to the catalytic domain of Polλ and specifically stimulates DNA gap filling by Polλ over 8-oxo-G followed by strand displacement synthesis. Our results suggest that WRN promotes long-patch DNA repair synthesis by Polλ during MUTYH-initiated repair of 8-oxo-G:A mispairs.

    Two PhD theses (Alexander Gordienko, 1912; Johannes Angerstein, 1914) and a dissertation in partial fulfillment of a PhD thesis (H. S. French, Zurich, 1914) are reviewed that deal with hitherto unpublished UV-vis spectroscopy work of coordination compounds in the group of Alfred Werner. The method of measurement of UV-vis spectra at Alfred Werner's time is described in detail. Examples of spectra of complexes are given, which were partly interpreted in terms of structure (cis ↔ trans configuration, counting number of bands for structural relationships, and shift of general spectral features by consecutive replacement of ligands). A more complete interpretation of spectra was hampered at Alfred Werner's time by the lack of a light absorption theory and a correct theory of electron excitation, and the lack of a ligand field theory for coordination compounds. The experimentally difficult data acquisitions and the difficult spectral interpretations might have been reasons why this method did not experience a breakthrough in Alfred Werner's group to play a more prominent role as an important analytical method. Nevertheless the application of UV-vis spectroscopy on coordination compounds was unique and novel, and witnesses Alfred Werner's great aptitude and keenness to always try and go beyond conventional practice.

  16. Competition between the DNA unwinding and strand pairing activities of the Werner and Bloom syndrome proteins

    Directory of Open Access Journals (Sweden)

    Orren David K

    2006-01-01

    Full Text Available Abstract Background The premature aging and cancer-prone Werner and Bloom syndromes are caused by defects in the RecQ helicase enzymes WRN and BLM, respectively. Recently, both WRN and BLM (as well as several other RecQ members have been shown to possess a strand annealing activity in addition to the requisite DNA unwinding activity. Since an annealing function would appear to directly oppose the action of a helicase, we have examined in this study the dynamic equilibrium between unwinding and annealing mediated by either WRN or BLM. Results Our investigation into the competition between annealing and unwinding demonstrates that, under standard reaction conditions, WRN- or BLM-mediated annealing can partially or completely mask unwinding as measured in standard helicase assays. Several strategies were employed to suppress the annealing activity so that the actual strength of WRN- or BLM-dependent unwinding could be more accurately assessed. Interestingly, if a DNA oligomer complementary to one strand of the DNA substrate to be unwound is added during the helicase reaction, both WRN and BLM unwinding is enhanced, presumably by preventing protein-mediated re-annealing. This strategy allowed measurement of WRN-catalyzed unwinding of long (80 base pair duplex regions and fully complementary, blunt-ended duplexes, both of which were otherwise quite refractory to the helicase activity of WRN. Similarly, the addition of trap strand stimulated the ability of BLM to unwind long and blunt-ended duplexes. The stimulatory effect of the human replication protein A (hRPA, the eukaryotic single-stranded DNA binding protein on both WRN- and BLM-dependent unwinding was also re-examined in light of its possible role in preventing re-annealing. Our results show that hRPA influences the outcome of WRN and BLM helicase assays by both inhibiting re-annealing and directly promoting unwinding, with the larger contribution from the latter mechanism. Conclusion These

    In this paper, we investigate the dynamical behaviour of entanglement in terms of concurrence in a bipartite system subjected to an external magnetic field under the action of dissipative environments in the extended Werner-like initial state. The interesting phenomenon of entanglement sudden death as well as sudden birth appears during the evolution process. We analyse in detail the effect of the purity of the initial entangled state of two qubits via Heisenberg XY interaction on the apparition time of entanglement sudden death and entanglement sudden birth. Furthermore, the conditions on the conversion of entanglement sudden death and entanglement sudden birth can be generalized when the initial entangled state is not pure. In particular, a critical purity of the initial mixed entangled state exists, above which entanglement sudden birth vanishes while entanglement sudden death appears. It is also noticed that stable entanglement, which is independent of different initial states of the qubits (pure or mixed state), occurs even in the presence of decoherence. These results arising from the combination of the extended Werner-like initial state and dissipative environments suggest an approach to control and enhance the entanglement even after purity induced sudden birth, death and revival.

    The enclathration of benzene and toluene by Werner complexes has been described. In the case of toluene, time-lapse PXRD analysis reveals that solid-liquid and solid-vapour reactions proceed according to different pathways. These preliminary results suggest that solid-liquid reactions destroy the host structure, whereas the solid-vapour reactions allow post-synthetic modification.

    2013-08-01

    Full Text Available In this work we attempt to analyze the intra-theoretic characterization provided by Hilary Putnam and Werner Heisenberg between quantum mechanics and other theories. The first defended the idea that physical theories include macro principles that under specific definite historical conditions can be revised on the light of rival principles. Putnam will concentrate in the impact that quantum mechanics has produced in the classical image of knowledge. Heisenberg, on the other hand, develops his analysis from the notion of closed theories, assuming the independence and incommensurability of physical theories. These divergences between the two authors will allow us to analyze how the disagreement in the consideration of the status of physical theories, goes deeper into more profound aspects related to the nature of knowledge and the relation between theory and world

    To present a rare anomaly consisting of uterus didelphys, longitudinal vaginal septum, obstructed hemivagina with pyocolpos, fistula to the open vaginal canal, and ipsilateral renal agenesis, referred as Herlyn-Werner-Wunderlich syndrome (HWWS). A 14-year-old girl with recurring purulent vaginal discharge lasting for a few months. Preoperative examination revealed one vaginal canal with one cervical opening on the right side. There was a fistula leading from the obstructed vaginal canal to the left vagina. Intravaginal ultrasound examination demonstrated a longitudinal vaginal septum and a closed pyocolpos on the right side. The longitudinal vaginal septum was excised by way of electrocauterization under direct vision. HWWS should be considered in the differential diagnosis in patients with uterus didelphys and unusual symptoms such as pyocolpos and vaginal discharge.

    2015-01-01

    Full Text Available Werner syndrome (WS is a progeroid or premature aging syndrome characterized by early onset of age-related pathologies and cancer. The average life expectancy of affected people is 52.8 years and tends to increase. The major causes of death are malignancy and myocardial infarction. Increased telomere attrition and decay are thought to play a causative role in the clinical and pathological manifestations of the disease. Although telomere length, with or without germline mutation, is known to be associated with interstitial lung disease, the latter is not associated with WS. To the best of our knowledge, we report the first case describing a WS patient with fatal ILD. This case suggests that older patients with WS could develop ILD. Clinical outcome of WS patients may thus be improved by counselling them regarding smoking cessation or other exposure and by proposing antifibrotic therapy.

    Herlyn-Werner-Wunderlich (HWW) syndrome is a very rare congenital anomaly of the urogenital tract involving Müllerian ducts and Wolffian structures, and it is characterized by the triad of didelphys uterus, obstructed hemivagina and ipsilateral renal agenesis. It generally occurs at puberty and exhibits non-specific and variable symptoms with acute or pelvic pain shortly following menarche, causing a delay in the diagnosis. Moreover, the diagnosis is complicated by the infrequency of this syndrome, because Müllerian duct anomalies (MDA) are infrequently encountered in a routine clinical setting. two cases of HWW syndrome in adolescents and a differential diagnosis for one case of a different MDA, and the impact of magnetic resonance (MR) imaging technology to achieve the correct diagnosis. MR imaging is a very suitable diagnostic tool in order to perform the correct diagnosis of HWW syndrome.

Two tertiary academic centers. None. The evaluation of the clinical features, ultrasonography and magnetic resonance imaging findings, and the treatment protocols. Ultrasonographic evaluation of didelphic or double uterus in 10 and bicornuate-bicollis uterus in 3 patients with hematocolpos or hematometrocolpos associated with agenesis of the ipsilateral kidney revealed the diagnosis. In 10 patients, magnetic resonance imaging provided extra information. In 1 patient, a 25-week pregnancy was additionally detected and follow-up was suggested. Seven patients underwent surgical excision of the septum and drainage of the obstructed vagina. Total hysterectomy and hemicolpectomy were performed in 1 patient with 2 children suffering from severe chronic pelvic pain due to pelvic inflammatory disease. Despite its rarity, accurate diagnosis and morphologic description of Herlyn-Werner-Wunderlich syndrome with radiologic modalities are of importance in relieving the clinical complaints by enabling the suitable surgical treatment to be identified.

    Instrumental Neutron Activation Analysis (INAA) is a multielementar technique with high sensitivity, and can be applied to study small samples. Therefore, this research proposes using the INAA for quantifying the accumulation of chemical elements in organs of anuran amphibians Rhinella schneideri (Werner, 1894). Male individuals were collected on areas with anthropogenic influence close to water resources on the campus of ESALQ/USP in 2009. The animals were sacrificed in a cold chamber and dissected to separate their kidneys, livers, lungs and skins. After cleaning, the organs were lyophilized and pulverized. Samples weighing from 200 to 500 mg were placed in polyethylene capsules to be irradiated. The INAA technique, based on the bombardment of samples with neutrons for the production of radionuclides, was applied using the Nuclear Research Reactor of the Nuclear and Energy Research Institute. Portions of certified reference materials were used to evaluate the quality of the analytical procedure. The mass fractions were quantified by the k0 method, and the results indicated differences among the As, Br, Co, Cr, Fe, Hg, Sc, Se and Zn concentrations in the analyzed organs. Therefore, it was possible to calculate the bioaccumulation indexes relative to these chemical elements for the species. In addition, it was possible to infer the contamination pathways: As, Br, Co, Cr and Se by ingestion and Co, Fe, Hg, Sc and Zn by contact, which corroborated the usage of R. schneideri anuran as a biomonitor of chemical elements.

    Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis is a rare entity, sometimes referred to as Herlyn-Werner-Wunderlich syndrome (HWW). It usually presents after menarche with progressive pelvic pain, sometimes with regular menses, and a palpable mass due to hemihaematocolpos. The diagnosis is generally made only if the suspicion of this genitourinary syndrome is raised. To highlight the imaging diagnostic clues in this rare condition. We report on 11 adolescents with this condition. Sonography mostly allowed the correct diagnosis by showing uterovaginal duplication, haematocolpos or haematometrocolpos, and the absence of the ipsilateral kidney. MRI provided more detailed information regarding uterine morphology, the continuity with each vaginal channel (obstructed and nonobstructed), and the bloody nature of the contents.

    Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis is a rare entity, sometimes referred to as Herlyn-Werner-Wunderlich syndrome (HWW). It usually presents after menarche with progressive pelvic pain, sometimes with regular menses, and a palpable mass due to hemihaematocolpos. The diagnosis is generally made only if the suspicion of this genitourinary syndrome is raised. To highlight the imaging diagnostic clues in this rare condition. We report on 11 adolescents with this condition. Sonography mostly allowed the correct diagnosis by showing uterovaginal duplication, haematocolpos or haematometrocolpos, and the absence of the ipsilateral kidney. MRI provided more detailed information regarding uterine morphology, the continuity with each vaginal channel (obstructed and nonobstructed), and the bloody nature of the contents. Early and accurate diagnosis of this syndrome is important so that adequate and prompt surgical therapy (excision of the vaginal septum) can provide relief of pain and prevent further complications. It is also advisable to look for an obstructed Muellerian system whenever a multicystic dysplastic kidney or the absence of a kidney is discovered in a fetus, or girl postnatally. (orig.)

  7. Reprogramming suppresses premature senescence phenotypes of Werner syndrome cells and maintains chromosomal stability over long-term culture.

    Full Text Available Werner syndrome (WS is a premature aging disorder characterized by chromosomal instability and cancer predisposition. Mutations in WRN are responsible for the disease and cause telomere dysfunction, resulting in accelerated aging. Recent studies have revealed that cells from WS patients can be successfully reprogrammed into induced pluripotent stem cells (iPSCs. In the present study, we describe the effects of long-term culture on WS iPSCs, which acquired and maintained infinite proliferative potential for self-renewal over 2 years. After long-term cultures, WS iPSCs exhibited stable undifferentiated states and differentiation capacity, and premature upregulation of senescence-associated genes in WS cells was completely suppressed in WS iPSCs despite WRN deficiency. WS iPSCs also showed recapitulation of the phenotypes during differentiation. Furthermore, karyotype analysis indicated that WS iPSCs were stable, and half of the descendant clones had chromosomal profiles that were similar to those of parental cells. These unexpected properties might be achieved by induced expression of endogenous telomerase gene during reprogramming, which trigger telomerase reactivation leading to suppression of both replicative senescence and telomere dysfunction in WS cells. These findings demonstrated that reprogramming suppressed premature senescence phenotypes in WS cells and WS iPSCs could lead to chromosomal stability over the long term. WS iPSCs will provide opportunities to identify affected lineages in WS and to develop a new strategy for the treatment of WS.

    Acrolein is a ubiquitous environmental hazard to human health. Acrolein has been reported to activate the DNA damage response and induce apoptosis. However, little is known about the effects of acrolein on cellular senescence. We examined whether acrolein induces cellular senescence in cultured normal human lung fibroblasts (NHLF). We cultured NHLF in the presence or absence of acrolein and determined the effects of acrolein on cell proliferative capacity, senescence-associated β-galactosidase activity, the known senescence-inducing pathways (e.g., p53, p21), and telomere length. We found that acrolein induced cellular senescence by increasing both p53 and p21. The knockdown of p53 mediated by small interfering RNA (siRNA) attenuated acrolein-induced cellular senescence. Acrolein decreased Werner's syndrome protein (WRN), a member of the RecQ helicase family involved in DNA repair and telomere maintenance. Acrolein-induced down-regulation of WRN protein was rescued by p53 knockdown or proteasome inhibition. Finally, we found that acrolein accelerated p53-mediated telomere shortening. These results suggest that acrolein induces p53-mediated cellular senescence accompanied by enhanced telomere attrition and WRN protein down-regulation.

    XPG is a structure-specific endonuclease required for nucleotide excision repair (NER). XPG incision defects result in the cancer-prone syndrome xeroderma pigmentosum, whereas truncating mutations of XPG cause the severe postnatal progeroid developmental disorder Cockayne syndrome. We show that XPG interacts directly with WRN protein, which is defective in the premature aging disorder Werner syndrome, and that the two proteins undergo similar sub-nuclear redistribution in S-phase and co-localize in nuclear foci. The co-localization was observed in mid- to late-S-phase, when WRN moves from nucleoli to nuclear foci that have been shown to contain protein markers of both stalled replication forks and telomeric proteins. We mapped the interaction between XPG and WRN to the C-terminal domains of each and show that interaction with the C-terminal domain of XPG strongly stimulates WRN helicase activity. WRN also possesses a competing DNA single-strand annealing activity that, combined with unwinding, has been shown to coordinate regression of model replication forks to form Holliday junction/chicken foot intermediate structures. We tested whether XPG stimulated WRN annealing activity and found that XPG itself has intrinsic strand annealing activity that requires the unstructured R- and C-terminal domains, but not the conserved catalytic core or endonuclease activity. Annealing by XPG is cooperative, rather than additive, with WRN annealing. Taken together, our results suggest a novel function for XPG in S-phase that is at least in part carried out coordinately with WRN, and which may contribute to the severity of the phenotypes that occur upon loss of XPG.

    Herlyn-Werner-Wunderlich syndrome is a rare Mullerian ductal anomaly that is characterized by the presence of a hemivaginal septum, a didelphic uterus and ipsilateral renal agenesis. It is generally difficult to diagnose the uterine malformation before menarche owing to its small size. Therefore, a follow-up study is very important for confirming the uterine malformation in girls with renal agenesis. We report a patient with renal agenesis and microscopic hematuria, who showed symptoms before menarche. A follow-up study eventually revealed uterine didelphys with a hemivaginal obstruction. A biopsy proved that the microscopic hematuria was caused by thin glomerular basement membrane disease of the contralateral kidney

  14. Investigating the role of c-Jun N-terminal kinases in the proliferation of Werner syndrome fibroblasts using diaminopyridine inhibitors

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Abstract Fibroblasts derived from the progeroid Werner syndrome show reduced replicative lifespan and a "stressed" morphology, both alleviated using the MAP kinase inhibitor SB203580. However, interpretation of these data is problematical because although SB203580 has the stress-activated kinases p38 and JNK1/2 as its preferred targets, it does show relatively low overall kinase selectivity. Several lines of data support a role for both p38 and JNK1/2 activation in the control of cellular proliferation and also the pathology of diseases of ageing, including type II diabetes, diseases to which Werner Syndrome individuals are prone, thus making the use of JNK inhibitors attractive as possible therapeutics. We have thus tested the effects of the widely used JNK inhibitor SP600125 on the proliferation and morphology of WS cells. In addition we synthesised and tested two recently described aminopyridine based inhibitors. SP600125 treatment resulted in the cessation of proliferation of WS cells and resulted in a senescent-like cellular phenotype that does not appear to be related to the inhibition of JNK1/2. In contrast, use of the more selective aminopyridine CMPD 6o at concentrations that fully inhibit JNK1/2 had a positive effect on cellular proliferation of immortalised WS cells, but no effect on the replicative lifespan of primary WS fibroblasts. In addition, CMPD 6o corrected the stressed WS cellular morphology. The aminopyridine CMPD 6r, however, had little effect on WS cells. CMDP 6o was also found to be a weak inhibitor of MK2, which may partially explain its effects on WS cells, since MK2 is known to be involved in regulating cellular morphology via HSP27 phosphorylation, and is thought to play a role in cell cycle arrest. These data suggest that total JNK1/2 activity does not play a substantial role in the proliferation control in WS cells.

  16. Association of the rs1346044 Polymorphism of the Werner Syndrome Gene RECQL2 with Increased Risk and Premature Onset of Breast Cancer

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Like other RECQ helicases, WRN/RECQL2 plays a crucial role in DNA replication and the maintenance of genome stability. Inactivating mutations in RECQL2 lead to Werner syndrome, a rare autosomal disease associated with premature aging and an increased susceptibility to multiple cancer types. We analyzed the association of two coding single-nucleotide polymorphisms in WRN, Cys1367Arg (rs1346044, and Arg834Cys (rs3087425, with the risk, age at onset, and clinical subclasses of breast cancer in a hospital-based case-control study of an Austrian population of 272 breast cancer patients and 254 controls. Here we report that the rare homozygous CC genotype of rs1346044 was associated with an approximately two-fold elevated breast cancer risk. Moreover, patients with the CC genotype exhibited a significantly increased risk of developing breast cancer under the age of 55 in both recessive and log-additive genetic models. CC patients developed breast cancer at a mean age of 55.2 ± 13.3 years and TT patients at 60.2 ± 14.7 years. Consistently, the risk of breast cancer was increased in pre-menopausal patients in the recessive model. These findings suggest that the CC genotype of WRN rs1346044 may contribute to an increased risk and a premature onset of breast cancer.

  17. The Berlin Mission Society and German linguistic roots of volkekunde: The background, training and Hamburg writings of Werner Eiselen, 1899-1924

    Directory of Open Access Journals (Sweden)

    Andrew Bank

    Full Text Available This article presents a case for the centrality of race and racism in the training and early ethnographic writings of Werner Eiselen (1899-1977. Together with further discussion in two other articles, it demonstrates that Eiselen was not the consolidator of the British functionalist anthropological tradition in South Africa nor a strong affiliate of the liberal school of African studies in South Africa as other scholars have proposed. On the contrary, he was the founder of a radically different ethnographic tradition: an anti-humanist and deeply racialised tradition of cultural study with its roots in Berlin Mission Society ideology and German Africanist linguistics. I track the origins of Eiselens volkekunde to his missionary background in a former Boer Republic, his Afrikaner nationalist schooling and university career, and especially to his training in African linguistics in Hamburg (and Berlin between 1921 and 1924 under the leading international figure in the field, the German linguist and ethnologist Carl Meinhof (1857-1944, whose racially informed theories and politics profoundly shaped Eiselen and the school of volkekunde that he would father during his decade-long tenure at Stellenbosch University.

    Werner mesomelic syndrome (WMS) is an autosomal dominant disorder with unknown molecular etiology characterized by hypo- or aplasia of the tibiae in addition to the preaxial polydactyly (PPD) of the hands and feet and/or five-fingered hand with absence of thumbs. We show that point mutations of a specific nucleotide within the sonic hedgehog (SHH) regulatory region (ZRS) cause WMS. In a previously unpublished WMS family, we identified the causative G>A transition at position 404 of the ZRS, and in six affected family members of a second WMS family we found a 404G>C mutation of the ZRS. The 404G>A ZRS mutation is known as the "Cuban mutation" of PPD type II (PPD2). Interestingly, the index patient of that family had tibial hypoplasia as well. These data provide the first evidence that WMS is caused by a specific ZRS mutation, which leads to strong ectopic SHH expression. In contrast, we show that complete duplications of the ZRS region lead to type Haas polysyndactyly or triphalangeal thumb-polysyndactyly syndrome, but do not affect lower limb development. We suggest the term "ZRS-associated syndromes" and a clinical subclassification for the continuum of limb malformations caused by different molecular alterations of the ZRS.

    2014-01-01

    The purpose of this article is the analyses of discussion between Albert Einstein and Werner Heisenberg in the period 1925-1927. Their disputes, relating to the sources of scientific knowledge, its methods and the value of knowledge acquired in this way, are part of the characteristic for the European science discourse between rationalism and empirism. On the basis of some sources and literature on the subject, the epistemological positions of both scholars in the period were reconstructed. This episode, yet poorly known, is a unique example of scientific disputes, whose range covers a broad spectrum of methodological problems associated with the historical development of science. The conducted analysis sheds some light on the source of popularity of logical empirism in the first half of the 20th century. A particular emphasis is placed on the impact of the neopositivist ideas which reflect Heisenberg's research program, being the starting point for the Copenhagen interpretation of quantum mechanics. The main assumption of logical empirism, concerning acquisition of scientific knowledge only by means of empirical procedures and logical analysis of the language of science, in view of the voiced by Einstein arguments, bears little relationship with actual testing practices in the historical aspect of the development of science. The criticism of Heisenberg's program, carried out by Einstein, provided arguments for the main critics of the neopositivist ideal and contributed to the bankruptcy of the idea of logical empirism, thereby starting a period of critical rationalism prosperity, arising from criticism of neopositivism and alluding to Einstein's ideas.

    Full Text Available In coordination chemistry the study of geometrical isomerization and reactivity of specific isomers is a topic of major importance. The preparation of specific isomers often requires considerable complexity, and it is important to acquire a sense of what is involved in studying isomerism in laboratory. If it is difficult sometimes to prepare pure isomers, it is not easier to understand the mechanisms of isomerization reactions since studies on this subject have shown conflicting results and diferent interpretations on the same system have been reported in the literature. Although cis-trans isomerism in octahedral metal complexes is a common occurrence, there are relatively few studies reporting how these isomerizations occur. This paper gives an overview on cis-trans isomerization processes and identification of these species.

    2018-04-01

    Quantum entanglement as a special resource inspires various distinct applications in quantum information processing. Unfortunately, it is NP-hard to detect general quantum entanglement using Bell testing. Our goal is to investigate quantum entanglement with white noises that appear frequently in experiment and quantum simulations. Surprisingly, for almost all multipartite generalized Greenberger-Horne-Zeilinger states there are entangled noisy states that satisfy all linear Bell inequalities consisting of full correlations with dichotomic inputs and outputs of each local observer. This result shows generic undetectability of mixed entangled states in contrast to Gisin's theorem of pure bipartite entangled states in terms of Bell nonlocality. We further provide an accessible method to show a nontrivial set of noisy entanglement with small number of parties satisfying all general linear Bell inequalities. These results imply typical incompleteness of special Bell theory in explaining entanglement.

    Genetic diagnosis of inherited metabolic disease is conventionally achieved through syndrome recognition and targeted gene sequencing, but many patients receive no specific diagnosis. Next-generation sequencing allied to capture of expressed sequences from genomic DNA now offers a powerful new diagnostic approach. Barriers to routine diagnostic use include cost, and the complexity of interpreting results arising from simultaneous identification of large numbers of variants. We applied exome-w...

  1. Biomedical program for the converted 200-MeV synchrocyclotron at the Gustaf Werner Institute

    International Nuclear Information System (INIS)

    Larsson, B.

    1985-01-01

    Between 1956 and 1977, the former synchrocyclotron in Uppsala was used for biological experiments and clinical tests with 185-MeV protons. Therapeutic irradiations have been performed since 1957 by cross-firing with pencil beams through small intracranial structures for the treatment of Parkinsonism and intractable pain and with the spread-out Bragg peak for the treatment of large malignant tumors. Radiological and radiophysical aspects of the use of charged-particle beams were studied in detail. The former accelerator is now being converted to a sector-focusing, frequency-modulated cyclotron, SFSC-200, to permit acceleration of protons up to 200 MeV and other light ions to corresponding energies. Production of spallation neutrons and radionuclides for biomedical uses is expected to start this year. Experiments with charged-particle beams will begin in 1986. This paper presents a discussion of accelerator developments for planned experimental and clinical programs

    Full Text Available The paper analyzes Talcott Parsons’ early essay published in two issues of The Journal of Political Economy in 1928 and 1929. ““Capitalism” in recent German Literature: Sombart and Weber”, which introduces both Sombart and Weber to the American public. It represents a relevant moment in the development of Parsons as a sociologist. After discussing Parsons’ interpretation of both Sombart’s and Weber’s theories about the origin of Capitalism, the paper gives an interpretation of Parsons’ role in the establishment of Weber as a founding father of sociology and the relative irrelevance of Sombart as a sociological classic.

    Emiliano Bevilacqua

    2015-03-01

    Full Text Available The authors discuss the Sombartian analysis of capitalism from a bioeconomic perspective, paying attention to the relationship between people’s lives and economy. The paper focuses on the influence of individual behaviors and values on the genesis and the stabilization of capitalism. The Sombartian analysis is discussed stressing the point that it offers interesting insights to understand the relationship between economy and the everyday life of the people: the spirit of capitalism, luxury and religious beliefs are examples of cultural phenomena from which economy cannot be separated. The thesis of the authors is that the Sombartian analysis through a sociological interpretation of history able to avoid any psychological reductionism puts life at the center of economy.

  18. The Notion of Capitalist Evolution in Werner Sombart in the light of the Modern Critiques of the Evolutionary Conceptions

    Directory of Open Access Journals (Sweden)

    Sandro Segre

    2015-03-01

    Full Text Available This essay reconstructs Sombart’s evolutionary conception of modern capitalism, focuses on the different stages of capitalist development which Sombart has conceptualized, and evaluates this conception in the light of the current debate on the fruitfulness of the evolutionary accounts of social change. A perusal of Sombart’s oeuvre has shown that Sombart’s conception of the capitalist social and historical change anticipates modernization theories, while avoiding the fallacies of Merton’s and Parsons’ functionalism; for Sombart reconstructs the plausible motivations of the actors playing a role in historical change and pursues a multi-factor account of historical change.

    2017-01-01

    The family Gymnophthalmidae contains nearly 235 species with a distribution range from southern Mexico to central Argentina as well as in the Antilles. Among gymnophthalmids, the genus Colobosaura is a member of the tribe Iphisini, and currently is considered monotypic ( C. modesta ). The diversity of the tribe was studied recently, with the erection of several new genera. In this work genetic and morphological data of specimens of Colobosaura recently collected in Paraguay were analyzed. Genetic (16S barcode) data indicate that these samples are not conspecific with C. modesta and they are allocated to the nominal species C. kraepelini . Because the original primary type of the latter taxon is considered to be lost, a neotype (SMF 101370) is designated for this species and a redescription provided based on our material. Colobosaura kraepelini is distributed in the Humid Chaco, being the only member of the whole tribe in this ecoregion.

It contains theoretical approaches to the theory of disability and introduces the reader to empirical research on the body and on cultures of disability. Cross-national approaches and analyses of the social and political situation give information on the situation of people with disabilities in Germany as well as internationally. The book discusses the recent debate on the social construction of disability in German academia. It also contributes to the new Anglo-American theoretical debate about the governmentality of disabilty and, for example, problematizes findings about blindness, personal assistance and segregation within the educational system.

    Steffen Großkopf

    2008-01-01

    Full Text Available The handbook gives a general overview of the established—but increasingly complex—theoretical and methodological practice of discourse analysis. The attempt is made to systematize the diversity of discourse analysis, with its different historical roots and fields of research in the social sciences, even though the focus is mainly on FOUCAULT's approach. Thus, the handbook has to be understood as an important step towards a insertion of discourse analysis into social science. Although there are unavoidable contradictions between the articles—almost because of the open theoretical foundations—the handbook characterizes, as a whole, discourse analysis as a heterogeneous strategy of research rather than as a stringent method. With this approach, it can be a helpful guide for the reader’s own research projects. However, if one is looking for a precise method, the investment of time in discourse analysis could be wasted.

  11. Hacia una Taxonomía Integral: poniendo a prueba especies candidatas relacionadas a Liolaemus buergeri Werner 1907 (Iguania: Liolaemini mediante análisis morfológicos

    Directory of Open Access Journals (Sweden)

    Avila, Luciano Javier

    2012-11-01

    Full Text Available La taxonomía tradicional ha estado basada en caracteres de morfología externa o interna, delimitando morfo-especies. En los últimos años comenzó a desarrollarse la denominada taxonomía integral, con el objetivo de integrar los conceptos y métodos básicos de la taxonomía tradicional con nuevos conceptos y metodologías. Dentro de esta aproximación las especies son hipótesis, y las hipótesis de especies más estables, son aquellas avaladas por diferentes tipos de caracteres independientes. Liolaemus es el género de lagartijas con más número de especies de América austral, y dentro del mismo se han propuesto varios clados y complejos. Uno de ellos es el grupo kriegi, que incluye las especies L. buergeri, L. ceii y L. kriegi. En base a tres marcadores mitocondriales, se han propuesto como especies candidatas a tres taxa cercanamente relacionados a L. buergeri: L. sp. A, L. sp. B y L. sp. C. El objetivo de este trabajo es analizar las variaciones morfológicas entre los taxa propuestos y los individuos de la localidad tipo de L. buergeri, a fin de aportar una fuente de evidencia nueva e independiente al análisis de las hipótesis de especies propuestas para este grupo. Se estudiaron individuos de toda el área de distribución de L. buergeri y de las especies candidatas. Para cada ejemplar se registraron caracteres morfométricos, de escamación y el número de poros precloacales en machos. Se encontraron diferencias significativas entre los taxa para las variables analizadas, y se hallaron diferencias en el grado de dimorfismo sexual. Los resultados de estos análisis indican que los taxa candidatos se pueden diferenciar morfológicamente y por lo tanto apoyan, de manera independiente, las hipótesis de especies planteadas por el análisis de DNA mitocondrial. Traditional taxonomy has usually been based mainly on characters of external or internal morphology to delimit morpho-species. Recent years have seen the emergence of "integrative taxonomy", with the objective of integrating the basic concepts and methods of traditional taxonomy with new concepts and methodologies. In this conceptual framework, species are treated as hypotheses and stable species’ hypotheses are those supported by different types of independent characters. The lizard genus Liolaemus has the highest species richness of southern South America, and several clades and complexes have been proposed. One of these is the kriegi group, which includes the species L. buergeri, L. ceii and L. kriegi. Based on three mitochondrial markers, three haploclades closely related to L. buergeri have been proposed as candidate species: L. sp. A, L. sp. B and L sp. C. The aim of this paper is to analyze the morphological variation in the proposed clades and individuals from the type locality of L. buergeri, in order to provide a source of new and independent evidence for the analysis of candidate species proposed for this group. We studied individuals across all the distributional range of L. buergeri and the candidate species. For each specimen we registered morphometric and meristic characters, and precloacal pores in males. We found significant differences among taxa for the analyzed variables, as well as in the degree of sexual dimorphism. The results of these analyzes indicate that the candidate taxa can be identified morphologically and therefore support, based on independent evidence, the “candidate species” hypotheses proposed based on mitochondrial DNA.

    Full Text Available In this book the author tries to show a connection between LUHMANN's systems theory and social research with a qualitative reconstructive methodology. Following a detailed theoretical introduction to the field, showing the background of the two concepts as well as the opportunities and challenges arising if they are to be connected, three chapters show practical applications in a medical context. In these studies the main approach discussed is BOHNSACK's documentary method. The book presents an effective and meticulous way of dealing with its main issue. Unfortunately, there is no clear link between the theoretical and the practical part of the book and the reader needs either already to have detailed knowledge of the area or else must achieve a lot in integrating the contents.

Three independent observers, two surgeons specializing in musculoskeletal tumour surgery and a medical student, tested the English language version of Wikipedia and the NCI “websites” on April 3, 2009. Answers to the 20 questions found on the websites were scored from zero to three and were discussed with a member of the "German board for guidelines in musculoskeletal surgery" (p. 373 and verified against international guidelines published by the World Health Organization. Data was analyzed using SPSS and group comparisons were performed using Mann-Whitney U test with p-values of less than 0.05 significance. Main Results – The quality of information about osteosarcoma found in the English language version of Wikipedia was good but inferior to the patient information from NCI. Out of a total of 60 points Wikipedia scored 33, NCI patient information 40 and NCI professional information 50. There was no significant difference between the NCI patient information and Wikipedia but a significant difference (p=0.039 between Wikipedia and NCI professional information.Conclusion – Non-peer reviewed websites providing health information, such as Wikipedia, should include links to sites such as NCI and other more definitive sources such as professional and international organizations. Frequent checks should be used to ensure external links are of the highest quality.

  2. Minimizing the loss of entanglement under dimensional reduction

    Science.gov (United States)

    Petersen, V.; Madsen, L. B.; Mølmer, K.

    2004-05-01

    We investigate the possibility of transforming, under local operations and classical communication, a general bipartite quantum state on a d A x d B tensor-product space into a final state in 2 x 2 dimensions, while maintaining as much entanglement as possible. For pure states, we prove that Nielsen’s theorem provides the optimal protocol, and we present quantitative results on the degree of entanglement before and after the dimensional reduction. For mixed states, we identify a protocol that we argue is optimal for isotropic and Werner states. In the literature, it has been conjectured that some Werner states are bound entangled and in support of this conjecture our protocol gives final states without entanglement for this class of states. For all other entangled Werner states and for all entangled isotropic states some degree of free entanglement is maintained. In this sense, our protocol may be used to discriminate between bound and free entanglement.

    In the present paper, quantum speed limit (QSL) time of a bipartite V-type three-level atomic system under the effect of two-qutrit entanglement is investigated. Each party interacts with own independent reservoir. By considering two local unitarily equivalent Werner states and the Horodecki PPT state, as initial states, the QSL time is evaluated for each of them in the respective entangled regions. It is counterintuitively observed that the effect of entanglement on the QSL time driven from each of the initial Werner states are completely different when the degree of non-Markovianity is considerable. In addition, it is interesting that the effect of entanglement of the non-equivalent Horodecki state on the calculated QSL time displays an intermediate behavior relative to the cases obtained for the Werner states.

    Werner syndrome is an inherited human progeriod syndrome caused by mutations in the gene encoding the Werner Syndrome protein, WRN. It has both 3'-5' DNA helicase and exonuclease activities, and is suggested to have roles in many aspects of DNA metabolism, including DNA repair and telomere...... D-loop model substrate. In addition, the length of telomeric G-tails decreases in DNA-PKcs knockdown cells, and this phenotype is reversed by overexpression of WRN helicase. These results suggest that WRN and DNA-PKcs may cooperatively prevent G-tail shortening in vivo....

When completed, the plant will burn about 200,000 tons of waste materials per year.El crecimiento considerable experimentado por la ciudad, el actual sistema de venta, en general, las nuevas instalaciones de calefacción y la prohibición a las fábricas de verter sus residuos en vertederos públicos ha creado la imperiosa necesidad de construir una nueva planta de incineración, con extraordinarias instalaciones y perfecto funcionamiento, que, progresivamente, ha de sustituir a la antigua, sin que ésta deje de funcionar, a fin de no crear nuevos problemas. Recientemente ha sido terminada la primera etapa; la segunda se acabará hacia 1980; después de la cual se demolerá la vieja fábrica y se acometerá la última fase, que será finalizada hacia 1985. En estas fechas, el complejo total quemará más de 200.000 t de desechos por año.

    We adopt a continuous model to estimate the Grothendieck constants. An analytical formula to compute the lower bounds of Grothendieck constants has been explicitly derived for arbitrary orders, which improves previous bounds. Moreover, our lower bound of the Grothendieck constant of order three gives a refined bound of the threshold value for the nonlocality of the two-qubit Werner states. (paper)

  3. Cooperation of DNA-PKcs and WRN helicase in the maintenance of telomeric D-loops

    2010-01-01

    Werner syndrome is an inherited human progeriod syndrome caused by mutations in the gene encoding the Werner Syndrome protein, WRN. It has both 3'-5' DNA helicase and exonuclease activities, and is suggested to have roles in many aspects of DNA metabolism, including DNA repair and telomere...... maintenance. The DNA-PK complex also functions in both DNA double strand break repair and telomere maintenance. Interaction between WRN and the DNA-PK complex has been reported in DNA double strand break repair, but their possible cooperation at telomeres has not been reported. This study analyzes thein vitro...... D-loop model substrate. In addition, the length of telomeric G-tails decreases in DNA-PKcs knockdown cells, and this phenotype is reversed by overexpression of WRN helicase. These results suggest that WRN and DNA-PKcs may cooperatively prevent G-tail shortening in vivo....

  4. The early S-matrix theory and its propagation (1942-1952)

    International Nuclear Information System (INIS)

    Rechenberg, H.

    1989-01-01

    This paper describes the development of S-matrix theory in the 1940s and 1950s, which described the scattering and emission problems in elementary particle theory. Its chief architect, Werner Heisenberg, worked in Germany all through the Second World War. Communication problems were intense and made discussion of this useful tool very difficult. Werner Heisenberg's collaborative efforts with Hendrik Kramers in Holland and Christian Moeller are noted. The theory had its opponents and their objections are described. As other scientists took up the theory it was used in new ways such as in quantum electrodynamics, and to predict the creation of massive particles by analyzing S-matrix threshold behaviour. Although the theory fell into disfavour in the early 1950s, it was later readopted when ideas such as crossed channels and analytic behaviour in the complex angular-momentum plane needed explanations.

  7. Trying to explain Copenhagen

    CERN Multimedia

    2003-01-01

    The documentary "The Copenhagen Fallout" recounts the friendship and "falling out" of Niels Bohr and Werner Heisenberg, two of the greatest contemporary physicists - friends whom war turned into enemies. It will be shown at CERN on 1st December. During a lecture in Germany towards the end of 1922, a 20-year-old physicist dared to interrupt Physics Nobel-Prize winner Niels Bohr with the words "There is a mathematical error in what you have said." The young scientist in question was none other than Werner Heisenberg. From this audacious beginning a fruitful collaboration and great friendship grew. But World War II threw up a wall of incomprehension between the two scientists, as one worked for the Nazi regime and the other opened his Copenhagen institute to German Jewish scientists. Then came their famous meeting in September 1941, dramatised by the no less famous play "Copenhagen", currently being performed in association with CERN at th...

Kirsten (WHK) student internship, I did not know what I know now. I only knew what each of Gandhi’s words meant individually. I now understand the full meaning of the phrase. To me, Gandhi’s words mean that nothing in life is handed to you. You have to work hard today to get the results you want tomorrow.

  11. Entanglement Evolution of Three-Qubit States under Local Decoherence

    International Nuclear Information System (INIS)

    Ma Xiaosan; Liu Gaosheng; Wang Anmin

    2010-01-01

    By using negativity as entanglement measure, we have investigated the effect of local decoherence from a non-Markovian environment on the time evolution of entanglement of three-qubit states including the GHZ state, the W state, and the Werner state. From the results, we find that the entanglement dynamics depends not only on the coupling strengths but also on the specific states of concern. Specifically, the entanglement takes different behaviors under weak or strong coupling and it varies with the quantum states under study. The entanglement of the GHZ state and the Werner state can be destroyed completely by the local decoherence, while the entanglement of the W state can survive through the local decoherence partially.

    Man'ko, V. I.; Markovich, L. A.

    2018-02-01

    Quantum correlations in the state of four-level atom are investigated by using generic unitary transforms of the classical (diagonal) density matrix. Partial cases of pure state, X-state, Werner state are studied in details. The geometrical meaning of unitary Hilbert reference-frame rotations generating entanglement in the initially separable state is discussed. Characteristics of the entanglement in terms of concurrence, entropy and negativity are obtained as functions of the unitary matrix rotating the reference frame.

    At a key time in his scientific development, Pauli was undergoing analysis by Jung. What can we learn about Pauli's discoveries of the exclusion principle and the CPT theorem, as well as his thoughts on non-conservation of parity, and his quest with Heisenberg for a unified field theory of elementary particles from Jung’s analysis of his dreams? A very different Pauli emerges, one at odds with esteemed colleagues such as Niels Bohr and Werner Heisenberg.

    The Heisenberg uncertainty principle shows that no one can specify the values of the non-commuting canonically conjugated variables simultaneously. However, the uncertainty relation is usually applied to two incompatible measurements. We present tighter bounds on both entropic uncertainty relation and information exclusion relation for multiple measurements in the presence of quantum memory. As applications, three incompatible measurements on Werner state and Horodecki's bound entangled state are investigated in details.

    Full Text Available The notion of (geological formation has gradually developed through mostly German terms: from ein Gebirge, which was used by Saxon miners for several centuries (AGRICOLA, then Schichten, Bergart (LEHMANN and serie montana (FUCHSEL to Gebirgsart (WERNER. The term ‘formation’ was introduced by WERNER in 1791 and its meaning was clearly defined around 1800. He included the notion of “formation” into his system of “geognostic structures”: mineral; rock (layer; formation; Earth’s crust. Therefore, it was an equivocal term from the start. It implied a geological body of certain composition, genesis and superposition (i.e. time of origination. After Werner, the term ‘formation’ was used in different ways, mostly as a synonym for a ‘system’, until 1881 when such use was forbidden. The original Wernerian sense of the term ‘formation’ (as a unit in geological levels of organisation: mineral-rock-formation-geosphere-planet with an intentionally equivocal meaning was not restored until the second half of the twentieth century.

  9. Decoherence of Two-qubits Coupled with Reservoirs Studied with New Ket-Bra Entangled State Method

    Science.gov (United States)

    Ren, Yi-Chong; Fan, Hong-Yi

    2016-04-01

    For the first time we define a so-called Ket-Bra Entangled State (KBES) for two-qubits coupled with reservoirs by introduce an extra fictitious mode vector, and convert the corresponding master equation into Schrödinger-like equation by virtue of this state. Via this approach we concisely obtain the dynamic evolution of two uncoupled qubits each immersed in local thermal noise. Based on this, the decoherence evolution for the extended Werner-like states is derived and how purity and temperature influence the concurrence is analyzed. This KBES method may also be applied to tackling master equations of limited atomic level systems.

    Herlyn-Werner-Wunderlich syndrome (HWWS), characterized by uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis, is an uncommon combined Mullerian and mesonephric duct anomaly, and its presentation in adulthood is even rarer. We report here a 22-year-old female presenting with primary infertility where magnetic resonance imaging (MRI) suggested the diagnosis of HWWS with endometriosis. In a patient of infertility with endometriosis and unilateral renal agenesis, diagnosis of HWWS should be suspected and MRI is the investigation of choice for such anomalies

    Accurate full-dimensional quantum mechanical thermal rate constant values have been calculated for the F+H{sub 2}{yields}HF+H reaction on the Stark-Werner ab initio potential energy surface. These calculations are based on a flux correlation functions and employ a rigorous statistical sampling scheme to account for the overall rotation and the MCTDH scheme for the wave packet propagation. Our results shed some light on discrepancies on the thermal rate found for previous flux correlation based calculations with respect to accurate reactive scattering results. The resonance pattern of the all-J cumulative reaction probability is analyzed in terms of the partial wave contributions.

The activities in High Energy Physics fall into three domains: Research with the local accelerator, participation in collaborations at international centers and work on the rebuilding of the Uppsala synchrocyclotron. A major subject of research in Physical Biology is control of growth and differentiation, as reflected in the kinetics of biochemical reactions or in the behaviour of healthy or malignant cells at various levels of organization.

    2009-01-01

    The evolution of professional child psychiatry partly took place against a historically difficult background: the National Socialism. Physicians who shaped the profession scientifically were at the same time offenders in forced sterilisation and euthanasia. Substanciated understanding of the professional history implies a differenciated examination of relevant biographies. The careers of Werner Villinger and Hans Heinze are being outlined and related to the historical context. A distinct and satisfactory understanding has not taken place during postwar period in Germany. However, in the meantime there has grown an awareness and also a consternation about the incidents due to research and publications.

    The discovery of nuclear fusion 50 years ago, man's entry into the new atomic age, occurred in a fateful era, marked by the Munich Agreement shortly before and the outbreak of World War II shortly afterwards. Werner Heisenberg, Germany's Number One Physicist, was, on the one hand, respected as a competent and 'useful' theoretician, but on the other, was reviled as a 'white Jew, the spirit of Einstein's spirit'. He plays a key role in answering the question of whether research at that time could have resulted in a German atomic bomb. (orig.) [de

    The quantification of publication activity and impact has become a key element in the evaluation of scientific excellence. However, it is unclear to what extent this grasps the diversity of research communication that accompanies the transition of scientific fields. This contribution investigates number, categorization, and impact of publications (i.e., publication patterns) of six scientists active at the cognitive turn, which promoted the information processing perspective on neuronal processes in different communities: Horace Barlow, Theodore Bullock, Ralph Gerard, Donald MacKay, Warren McCulloch, and Werner Reichardt. The large variety of publication patterns revealed indicates the limits of standardized evaluation procedures based on publication activity.

  8. Sudden entanglement death, and ways to avoid it

    International Nuclear Information System (INIS)

    Eberly, J.H.; Ting Yu

    2005-01-01

    We report that non-communicating but entangled qubit pairs are almost universally liable to sudden entanglement death. In the presence of minor and purely local environmental noises their mixed-state entanglement may abruptly become zero long before the noises are able to destroy the local qubit coherence. Despite the inability of unitary transformations to alter entanglement, for example of Werner states, unitary transformations have been found to delay or defeat the sudden death event. These results upset the conventional understanding that entanglement lifetime can be estimated from qubit lifetime. This is not even approximately or qualitatively true. (author)

    We discuss some new features of the model of two two-level atoms interacting with two single-mode thermal cavity field via multi-photon transitions under intensity-dependent coupling. We examine the dynamics of quantum and classical correlations of the system initially exists in Werner states. The results show that the sudden death and sudden birth of quantum entanglement occur but the geometric measure of quantum discord remains non-zero. It is observed that, by increasing the number of photons, the periods become shorter and the quantum discord and entanglement become irregular.

    Electrostatic pickups around the circumference of the AA served for the measurement of the closed orbits across the wide momentum range of +- 3% to either side of central orbit. The pickups were of the "shoebox" type, with diagonal cuts, a horizontal and a vertical one mechanically coupled together. They were located where they would not require extra space. The small ones, like the one we see here, were inserted into the vacuum chamber of the BLG (long and narrow) bending magnets. Werner Sax contemplates his achievement.

    2018-01-01

    Full Text Available In order to explain the success of populist politicians use of social media, we need to subtract the social from relationality and separate social relationships from network theory applications. A pure theory of relationality is suggested by Werner Heisenberg’s breakthrough in quantum mechanics. It is argued that sociology, to its detriment, has failed to incorporate a theory of communication, one adequate to the explosion of social media and the recent rise of populist politics, here instanced by Donald Trump. Realizing the underlying importance of communication technology in all social relationships, and treating these two aspects in a complementary fashion, is the purpose of this essay in sociological theory.

    Some properties of the quantum discord based on the geometric measure advanced by Dakic et al (2010 Phys. Rev. Lett. 105 190502) are discussed here by recourse to a systematic survey of the two-qubit state-space, with emphasis on Werner and MEM states. We explore the dependence of quantum discord on the degree of mixedness of the bipartite states, and also its connection with non-locality as measured by the maximum violation of a Bell inequality within the CHSH scenario. Some considerations regarding the XY model are also made. (paper)

    We investigate the distillability of bipartite quantum states in terms of positive and completely positive maps. We construct the so-called generalized Choi states and show that it is distillable when it has negative partial transpose. We convert the distillability problem of 2-copy n× n Werner states into the determination of the positivity of an Hermitian matrix. We obtain several sufficient conditions by which the positivity holds. Further, we investigate the case n=3 by the classification of 2× 3× 3 pure states.

    Open quantum system dynamics of random unitary type may in principle be fully undone. Closely following the scheme of environment-assisted error correction proposed by Gregoratti and Werner [J. Mod. Opt. 50, 915 (2003)], we explicitly carry out all steps needed to invert a phase-damping error on a single qubit. Furthermore, we extend the scheme to a mixed-state environment. Surprisingly, we find cases for which the uncorrected state is closer to the desired state than any of the corrected ones.

    We employ the technique of weak measurement in order to enable preservation of teleportation fidelity for two-qubit noisy channels. We consider one or both qubits of a maximally entangled state to undergo amplitude damping, and show that the application of weak measurement and a subsequent reverse operation could lead to a fidelity greater than 2/3 for any value of the decoherence parameter. The success probability of the protocol decreases with the strength of weak measurement, and is lower when both the qubits are affected by decoherence. Finally, our protocol is shown to work for the Werner state too.

    In this paper, by exploiting the weak measurement and quantum measurement reversal procedure, we propose a scheme to show how one can protect the geometric quantum discord (GQD) of a two-qutrit V-type atomic system each of which interacts with a dissipative reservoir independently. We examine the scheme for the GQD of the initial two-qutrit Werner and Horodecki states for different classes of weak measurement strengths. It is found out that the presented protocol enables us to suppress decoherence due to the amplitude damping channel and preserve the quantum discord of the two-qutrit system successfully.

En esta investigación se analiza la aplicación de la madera laminada del Pinus caribaea Morelet, var. hondurensis; cultivado en la Orinoquia venezolana, para fabricar sistemas estáticos curvos, dentro de procedimientos edificatorios en construcciones ecológicas y sustentables. El objetivo general propone definir un modelo estructural de arcos que simplifique las labores de producción, transporte, pre-ensamblado, montaje, aprovechamiento, transformabilidad, deconstrucción y reciclaje; que justifique los principios de desarrollo tecnológico ecosustentable basados en las innovaciones tecnológicas de la madera laminada de pino Caribe. La metodología empleada permitió analizar comparativamente y describir los predimensionamientos del peralte de distintos componentes estructurales portantes, que responden eficientemente a esfuerzos de flexo-compresión, configurados a partir de los diagramas de momentos flexionantes de vigas rectas simplemente apoyadas y empotradas y son geométricamente análogos a sistemas de arcos bi o triarticulados. Entre las conclusiones se determina que la arquitectura ecosustentable queda definida como el conjunto de medidas que aportan soluciones constructivas que no dañan el medio ambiente; que emplea, además, materiales naturales renovables, respeta los ecosistemas, construye sin desperdicios; que deconstruye y recicla, sin demoler ni generar escombros.

    Why did Werner Heisenberg, a participant in the nuclear research programme of the Third Reich, visit his friend and mentor Niels Bohr in occupied Denmark in September 1941? Was it a deliberate attempt to mislead the allies through talking to Bohr? Or was he really pursuing the utopian goal of halting the race to build the atomic bomb? What the historians have never been able to fully explain is explored in the play "Copenhagen", in which the ghosts of the two great scientists try to fathom why they failed to understand each other all those years ago. "Copenhagen", which has filled theatres in London, New York and Paris, is one of the most successful plays of British author Michael Frayn, also famous for his crime thrillers and comedies. A production of the play in French will be staged at the Théâtre de Carouge from 18th November.

    Highlights: {yields} In this study, we investigated the effect of a DNA secondary structure on the two WRN activities. {yields} We found that a DNA secondary structure of the displaced strand during unwinding stimulates WRN helicase without coordinate action of WRN exonuclease. {yields} These results imply that WRN helicase and exonuclease activities can act independently. -- Abstract: Werner syndrome (WS) is an autosomal recessive premature aging disorder characterized by aging-related phenotypes and genomic instability. WS is caused by mutations in a gene encoding a nuclear protein, Werner syndrome protein (WRN), a member of the RecQ helicase family, that interestingly possesses both helicase and exonuclease activities. Previous studies have shown that the two activities act in concert on a single substrate. We investigated the effect of a DNA secondary structure on the two WRN activities and found that a DNA secondary structure of the displaced strand during unwinding stimulates WRN helicase without coordinate action of WRN exonuclease. These results imply that WRN helicase and exonuclease activities can act independently, and we propose that the uncoordinated action may be relevant to the in vivo activity of WRN.

    ''Quanta 3'' contains the speeches of the general assembly of the Heisenberg society in october 2014 and a speech of Werner Heisenberg about his talks with Albert Einstein, which he has hold in the year 1974 in the Einstein House in Ulm. The speech of Harald Lesch is dedicated to the question, which role plays quantum mechanics in the development of the Universe. In the second speech Karl Jacobs, one of the leading scientists in the ATLAS experiment at CERN, the discovery of the Higgs boson. The Heisenberg Society is dedicated to the mediation of the mental heritage of Werner Heisenberg. He was one of the most important scientists of the 20th century. With his quantum mechanics he opened for us the world of the smallest components of matter, the atoms,nuclei, and elementary particles. It makes also possible the description of the physical properties of molecules, chemical compounds, crystals, solids, and semiconductors and is so the base of the contemporary computer techniques. Heisenberg's discovery of the uncertainty relation has far reaching consequences for natural philosophy ant theory of knowledge and for the development of the cosmos.

  2. The effects of safer-sex stories on college students' attitudes toward condoms.

    Wright, S S; Kyes, K B

    1996-01-01

    Social learning theory predicts that reading non-erotic stories involving condom use will be as effective as reading erotic stories with condom use in producing positive attitudes toward condoms. Werner's orthogenetic principle, however, predicts that reading erotic condom stories will be most effective because of the link created between sexual arousal and cognitive information about condoms. 168 male and 149 female undergraduates enrolled in Introductory Psychology at a small, private, southern university participated in a study to test the validity of these two theories. The students read one of the following types of stories: erotic with condom placement described, erotic without condom use, or non-erotic with a model for discussing condoms. The men and women who read the non-erotic stories were most positive about condoms and reported the strongest intentions to use condoms in the future. These findings suggest that erotica is not necessary to produce positive attitudes toward condoms.

  3. The mystery of the seven spheres how homo sapiens will conquer space

    Bignami, Giovanni F

    2015-01-01

    In this book, Giovanni Bignami, the outstanding Italian scientist and astronomer, takes the reader on a journey through the “seven spheres”, from our own planet to neighboring stars. The author offers a gripping account of the evolution of Homo Sapiens to the stage where our species is developing capabilities, in the form of new energy propulsion systems, that will enable us to conquer space. The reader will learn how we first expanded our activities to reach beyond our planet, to the Moon, and how nuclear energy, nuclear fusion, and matter–antimatter annihilation will enable us to extend our exploration. After Mars and Jupiter we shall finally reach the nearest stars, which we now know are surrounded by numerous planets, some of which are bound to be habitable. The book includes enticing descriptions of such newly discovered planets and also brings alive key historical characters in our story, such as Jules Verne and Werner von Braun.

    Schäfer, Wolf

    2014-01-01

    In a letter to his wife from October 14, 1943, Werner Heisenberg describes a fierce clash with Carl Friedrich von Weizsäcker. The sudden conflict raises numerous questions, two of which are tackled here. First: How is now the friendly relationship between Heisenberg and Weizsäcker in the postwar years to be understood? The answer is: as a strategic performance. Second: How are the radical opinions to be explained that Weizsäcker expressed at the time? A thorough reconstruction of the lifelong connection that Weizsäcker maintained with Martin Heidegger and Heidegger's philosophy gives the answer: the young Weizsäcker was fired up by the "utopian" National Socialism with which Heidegger trumped the real existing.

    Nakagawa, Y.

    1980-01-01

    A method of analysis for the MHD initial-boundary problem is presented in which the model's formulation is based on the method of nearcharacteristics developed by Werner (1968) and modified by Shin and Kot (1978). With this method, the physical causality relationship can be traced from the perturbation to the response as in the method of characteristics, while achieving the advantage of a considerable reduction in mathematical procedures. The method offers the advantage of examining not only the evolution of nonforce free fields, but also the changes of physical conditions in the atmosphere accompanying the evolution of magnetic fields. The physical validity of the method is demonstrated with examples, and their significance in interpreting observations is discussed.

    2017-07-01

    The protein associated with Werner syndrome (WRN), is involved in DNA repair, checkpoint activation, and telomere maintenance. To better understand the involvement of WRN in double-strand DNA break (DSB) repair, we analyzed the combinatorial role of WRN-1, the Caenorhabditis elegans WRN helicase, in conjunction with EXO-1 and DNA-2 nucleases. We found that WRN-1 cooperates with DNA-2 to resect DSB ends in a pathway acting in parallel to EXO-1. The wrn-1 mutants show an aberrant accumulation of replication protein A (RPA) and RAD-51, and the same pattern of accumulation is also observed in checkpoint-defective strains. We conclude that WRN-1 plays a conserved role in the resection of DSB ends and mediates checkpoint signaling, thereby influencing levels of RPA and RAD-51. © 2017 Federation of European Biochemical Societies.

  13. Radiative feedback by low-mass stars in the first generation

    2009-01-01

    The survival of cosmological minihalos in both ionizing and Lyman-Werner (LW) UV fields from nearby and distant sources has attracted recent attention for its role in regulating the rise of stellar populations at high red-shifts. Numerical models suggest that the first stars form in isolation in small dark matter halos of ∼ 10 5 -10 7 M · at z ∼ 20-30 and that they are very massive, 25-500 M · . These stars form large H II regions 2.5-5 kpc in radius capable of engulfing nearby halos. With the rise of Population III stars throughout the cosmos also comes a global LW background that sterilizes mini-halos of H 2 , delaying or preventing new star formation in them. At high redshifts, ionizaing radiation is therefore relatively local while LW photons can originate from many megaparsects away because their energies lie below the ionization limit of H.

    Khorasani, Sasan Torabzadeh; Almasifard, Maryam

    2017-11-01

    This paper presents a dual-objective facility programming model for a green supply chain network. The main objectives of the presented model are minimizing overall expenditure and negative environmental impacts of the supply chain. This study contributes to the existing literature by incorporating uncertainty in customer demand, suppliers, production, and casting capacity. An industrial case study is also analyzed to reveal the feasibility of the proposed model and its application. A fuzzy approach which is known as TH is used to solve the suggested dual-objective model. TH approach is integration of a max-min method (LH) and modified version of Werners' approach (MW). The outcome of this study reveals that the presented model can support green supply chain network in different levels of uncertainty. In presented model, cost and negative environmental impacts derived from the supply chain network will increase of higher levels of uncertainty.

    2011-01-01

    Full Text Available This paper deals with the Multiobjective Linear Transportation Problem that has fuzzy cost coefficients. In the solution procedure, many objectives may conflict with each other; therefore decision-making process becomes complicated. And also due to the fuzziness in the costs, this problem has a nonlinear structure. In this paper, fuzziness in the objective functions is handled with a fuzzy programming technique in the sense of multiobjective approach. And then we present a compensatory approach to solve Multiobjective Linear Transportation Problem with fuzzy cost coefficients by using Werner's and operator. Our approach generates compromise solutions which are both compensatory and Pareto optimal. A numerical example has been provided to illustrate the problem.

    Full text: In Werner Lindingers laboratory we have developed a mass spectrometric technique, named proton-transfer-reaction mass-spectrometry (PTR-MS), which utilizes positive ion chemistry to measure trace neutral concentrations in air. During the last few years PTR-MS has been used in food research, in medical applications, and in environmental applications to gain gas phase information of volatile organic compounds (VOCs) at parts per trillion (pptv) levels. The real time method relies on proton transfer reactions between H 3 O + primary ions and organic trace gases (VOCs) which have a higher proton affinity than water molecules. Organic trace gases such as hydrocarbons, carbonyls, alcohols, acetonitrile, and others can be monitored on-line. In this lecture we will discuss the mass spectrometric method and present recent results gained in the field of environmental trace gas analysis. (author)

    How highly abstract quantum concepts were represented in language, and how these concepts were later taken up by philosophers, literary critics, and new-age gurus. The principles of quantum physics -- and the strange phenomena they describe -- are represented most precisely in highly abstract algebraic equations. Why, then, did these mathematically driven concepts compel founders of the field, particularly Erwin Schrödinger, Niels Bohr, and Werner Heisenberg, to spend so much time reflecting on ontological, epistemological, and linguistic concerns? What is it about quantum concepts that appeals to latter-day Eastern mystics, poststructuralist critics, and get-rich-quick schemers? How did their interpretations and misinterpretations of quantum phenomena reveal their own priorities? In this book, Jennifer Burwell examines these questions and considers what quantum phenomena -- in the context of the founders' debates over how to describe them -- reveal about the relationship between everyday experience, percep...

    We study the exact evolution of two noninteracting qubits, initially in a Bell state, in the presence of an environment, modeled by a kicked Ising spin chain. Dynamics of this model range from integrable to chaotic and we can handle numerics for a large number of qubits. We find that the entanglement (as measured by concurrence) of the two qubits has a close relation to the purity of the pair, and closely follows an analytic relation derived for Werner states. As a collateral result we find that an integrable environment causes quadratic decay of concurrence as well as of purity, while a chaotic environment causes linear decay. Both quantities display recurrences in an integrable environment

    The German atom bomb is a chimera. Scientists such as Carl Friedrich von Weizsaecker and Werner Heisenberg have been claiming for a long time that they refused to carry out research in the Third Reich because they did not want to put such a terrible weapon into Hitler's hand. The author produces evidence proving that the German physicists were never in a position to carry out a research project on the scale of the 'Manhattan Project', quite apart from the fact that they were lacking important technical prerequisites for splitting isotopes. With a detective's touch the author succeeds in reconstructing the competition for the bomb in minute detail. This book is the most detailed and precise analysis of the reality of that uranium machine which for four decades has haunted scientific and journalistic literature. (orig./HP) [de

    Werner's syndrome (WS) is a rare autosomal disease characterized by the premature onset of several age-associated pathologies. The protein defective in patients with WS (WRN) is a helicase/exonuclease involved in DNA repair, replication, transcription and telomere maintenance. In this study, we...... show that a knock down of the WRN protein in normal human fibroblasts induces phosphorylation and activation of several protein kinase C (PKC) enzymes. Using a tandem affinity purification strategy, we found that WRN physically and functionally interacts with receptor for activated C-kinase 1 (RACK1......), a highly conserved anchoring protein involved in various biological processes, such as cell growth and proliferation. RACK1 binds strongly to the RQC domain of WRN and weakly to its acidic repeat region. Purified RACK1 has no impact on the helicase activity of WRN, but selectively inhibits WRN exonuclease...

    The discovery of cosmic rays by Victor Hess during a balloon flight in 1912 at an altitude of 5350 m would not have been possible without the more than one hundred years development of scientific ballooning. The discovery of hot air and hydrogen balloons and their first flights in Europe is shortly described. Scientific ballooning was mainly connected with activities of meteorologists. It was also the geologist and meteorologist Franz Linke, who probably observed first indications of a penetrating radiation whose intensity seemed to increase with the altitude. Karl Bergwitz and Albert Gockel were the first physicists studying the penetrating radiation during balloon flights. The main part of the article deals with the discovery of the extraterrestrial radiation by V. Hess and the confirmation by Werner Kolhörster.

    2015-01-01

    Bartel Leendert van der Waerden made major contributions to algebraic geometry, abstract algebra, quantum mechanics, and other fields. He liberally published on the history of mathematics. His 2-volume work Modern Algebra is one of the most influential and popular mathematical books ever written. It is therefore surprising that no monograph has been dedicated to his life and work. Van der Waerden’s record is complex. In attempting to understand his life, the author assembled thousands of documents from numerous archives in Germany, the Netherlands, Switzerland and the United States which revealed fascinating and often surprising new information about van der Waerden. Soifer traces Van der Waerden’s early years in a family of great Dutch public servants, his life as professor in Leipzig during the entire Nazi period, and his personal and professional friendship with one of the great physicists Werner Heisenberg. We encounter heroes and villains and a much more numerous group in between these two extremes. ...

    The European Stroke Organisation (ESO) held its first European Stroke Science Workshop in Garmisch-Partenkirchen, Germany (15-17 December 2011). Stroke experts based in Europe were invited to present and discuss their current research. The scope of the workshop was to review the most recent findings of selected topics in stroke, to exchange ideas, to stimulate new research and to enhance collaboration between European stroke research groups. Seven scientific sessions were held, each starting with a keynote lecture to review the state of the art of the given topic, followed by 4 or 5 short presentations by experts. They were asked to limit their presentations to 10 slides containing only recent information. The meeting was organized by the executive committee of the ESO (Heinrich Mattle, chairman, Michael Brainin, Angel Chamorro, Werner Hacke, Didier Leys) and supported by the European Stroke Conference (Michael Hennerici). In this article we summarize the main contents of this successful workshop. PMID:22836350

    Full text: Traditional areas of forensic science, such as, handwriting and fingerprint examinations and the newer sciences such as molecular biology are increasingly being scrutinized and challenged by the legal and scientific communities. These older forensic disciplines are targets for critics and skeptics as they are not founded on the traditional sciences but have rather an empirical basis and are supported by what may be considered quasi-validated data. This paper discusses in broad terms the basis of these legal and scientific attitudes and the various solutions to overcoming these negative perceptions.

    A molecular hydrogen absorber at a lookback time of 12.4 billion years, corresponding to 10% of the age of the Universe today, is analyzed to put a constraint on a varying proton-electron mass ratio, μ. A high resolution spectrum of the J1443+2724 quasar, which was observed with the Very Large Telescope, is used to create an accurate model of 89 Lyman and Werner band transitions whose relative frequencies are sensitive to μ, yielding a limit on the relative deviation from the current laboratory value of Δμ/μ=(-9.5 ± 5.4(stat)± 5.3(syst))×10(-6).

    Half-life values of spontaneous nuclear decay processes are presented in the framework of the Effective Liquid Drop Model (ELDM) using the combination of varying mass asymmetry shape description for the mass transfer with Werner-Wheeler's inertia coefficient V MAS /WW. The calculated half-lives of ground-state to ground-state transitions for the proton emission, alpha decay, cluster radioactivity, and cold fission processes are compared with experimental data. Results have shown that the ELDM is a very efficient model to describe these different decay processes in a same, unified theoretical framework. A Table listing the predicted half-life values, τ c is presented for all possible cases of spontaneous nuclear break-up such that -7.30 10 τ c [S] 10 (τ/τ c ) > -17.0, where τ is the total half-life of the parent nucleus.

ReadingMacunaíma, by Mário de Andrade, a canonical vanguard text, or the forgotten early detective novels of Medeiros de Albuquerque, which did not make it into the canon, the question rises about what thecanon is, keeping in mind that it is impossible to return to thingspast, but only to things in the past which have a place in thefuture.

  1. Light deflection by charged wormholes in Einstein-Maxwell-dilaton theory

    Science.gov (United States)

    Jusufi, Kimet; Övgün, Ali; Banerjee, Ayan

    2017-10-01

    In this paper, we study the deflection of light by a class of charged wormholes within the context of the Einstein-Maxwell-dilaton theory. The primordial wormholes are predicted to exist in the early universe, where inflation is driven by the dilaton field. We perform our analysis through optical geometry using the Gibbons-Werner method (GW) by adopting the Gauss-Bonnet theorem and the standard geodesics approach. We report an interesting result for the deflection angle in leading-order terms—namely, the deflection angle increases due to the electric charge Q and the magnetic charge P , whereas it decreases due to the dilaton charge Σ . Finally, we confirm our findings by means of geodesics equations. Our computations show that the GW method gives an exact result in leading-order terms.

  2. Figure-of-merit analysis and cost effectiveness of low-level radioactive waste treatment systems

    Science.gov (United States)

    Cox, N. D.; Falconer, K. L.; McCormack, M. D.; Hootman, H. D.; Thompson, T. K.

    Two studies were performed to assess low level waste treatment systems that are available commercially for volume reduction and/or solidification. In the first, a Figure-of-Merit (FOM) decision analysis technique was used to evaluate fourteen low level radioactive waste processing systems on their ability to treat power reactor wastes. The assessment of the various processing systems was accomplished using a five member task force. The systems were judged on eleven major criteria and twenty subcriteria. The system judged superior to all the others was compaction of dry wastes with liquid wastes and sludges being directly incorporated into concrete. This was also the lowest cost system. The controlled air incinerator was judged the preferred incineration process. The Werner-Pfleider bitumen extruduer was the preferred liquid waste treatment system. In the second study, the cost economy of volume reduction measured in land disposal dollars was investigated.

  3. Nobel Prize nominees and the rise of urology in Europe around 1900.

    Recent historical research has reconstructed the roads leading to the Nobel Prize for the trained urologists Werner Forssmann (1904-1979) in 1956 and Charles Huggins (1901-1997) in 1966. However, the story of urology and the Nobel Prize does not start and end with the laureates. Taking James Israel (1848-1926), Félix Guyon (1831-1920), and Peter J Freyer (1852-1921) as examples, this paper shows that pioneers in urology were in fact runners-up for the award much earlier. The study is based on an analysis of original files in the Nobel Prize archive in Stockholm, scientific publications of the early twentieth century, and secondary literature. We argue that Israel's, Guyon's, and Freyer's candidacies reflect not only scientific trends and controversies in urology at the turn of twentieth century, but that the development of the specialty itself was reflected in nominations of physicians working on problems of the genito-urinary system.

    Our research group has reconstructed why the board certified urologists Werner Forssmann (1904-1979) and Charles Huggins (1901-1997) received the Nobel Prize in physiology or medicine (1956, and 1966, respectively). But the history of "Urology and the Nobel Prize" is in fact more multifaceted than the success stories of these two laureates suggest. James Israel (1848-1926), Berlin, Félix Guyon (1831-1920), Paris, Peter J. Freyer (1852-1921), London and Edwin Beer (1876-1938), New York were nominated for the award during the first three decades of the 20th century. Their candidacies mirror trends among leading urologists during the time when urology became a specialty in its own right.

    1992-01-01

    Two accelerators at The Svedberg Laboratory in Uppsala, the Gustaf Werner cyclotron and the CELSIUS ring, will get a new control system. At present both the cyclotron and the ring have their own control systems based on S99 and PDP-11 minicomputers respectively. There are also a number of subsystems which are controlled separately from the stand-alone PC based consoles (ECR ion source, electron cooler, vacuum system). The goal of the rejuvenation is to integrate all existing control systems and provide the new system with an uniform operators interface based on workstations. The obsolete S99 microcomputers will be substituted with a VME system and all subsystems will be connected to the Ethernet. The upgrade strategy enabling the transformation of the system without any long shut-down period is discussed. Hardware and software planned for the upgrade is presented together with a discussion of expected problems. (author)

  8. Philosophy of biology: about the fossilization of disciplines and other embryonic thoughts.

    Science.gov (United States)

    Van Speybroeck, Linda

    2007-01-01

    This paper focuses on a running dispute between Werner Callebaut's naturalistic view and Filip Kolen and Gertrudis Van de Vijver's transcendentalist view on the nature of philosophy of biology and the relation of this discipline to biological sciences. It is argued that, despite differences in opinion, both positions agree that philosophy of biology's ultimate goal is to 'move' biology or at least be 'meaningful' to it. In order to make this goal clear and effective, more is needed than a polarizing debate which hardly touches upon biology. Therefore, a redirection in discussion is suggested towards a reflection on the possibilities of incorporating philosophy in interdisciplinary research, and on finding concrete research questions which are of interest both to the philosopher and to the biologist.

    We give a multidimensional generalization of the complete set of Bell-correlation inequalities given by Werner and Wolf (2001 Phys. Rev. A 64 032112) and by Zukowski and Brukner (2002 Phys. Rev. Lett. 88 210401), for the two-dimensional case. Our construction applies to the n-party, two-observable case, where each observable is d-valued. The d d n inequalities obtained involve homogeneous polynomials. They define the facets of a polytope in a complex vector space of dimension d n . We detail the inequalities obtained in the case d = 3 and, from them, we recover known inequalities. We finally explain how the violations of our inequalities by quantum mechanics can be computed and could be observed, when using unitary observables. (paper)

  10. Uncertainty Einstein, Heisenberg, Bohr, and the struggle for the soul of science

    CERN Document Server

    Lindley, David

    2007-01-01

    The uncertainty in this delightful book refers to Heisenberg's Uncertainty Principle, an idea first postulated in 1927 by physicist Werner Heisenberg in his attempt to make sense out of the developing field of quantum mechanics. As Lindley so well explains it, the concept of uncertainty shook the philosophical underpinnings of science. It was Heisenberg's work that, to a great extent, kept Einstein from accepting quantum mechanics as a full explanation for physical reality. Similarly, it was the Uncertainty Principle that demonstrated the limits of scientific investigation: if Heisenberg is correct there are some aspects of the physical universe that are to remain beyond the reach of scientists. As he has done expertly in books like Boltzmann's Atom, Lindley brings to life a critical period in the history of science, explaining complex issues to the general reader, presenting the major players in an engaging fashion, delving into the process of scientific discovery and discussing the interaction between scien...

  11. Quantum discord for a central two-qubit system coupled to an XY-spin-chain environment

    International Nuclear Information System (INIS)

    Liu Benqiong; Shao Bin; Zou Jian

    2010-01-01

    We investigate the dynamic behaviors of quantum discord for a central two-qubit system coupled to an XY-spin-chain environment. In the weak-coupling regime, we show that the quantum discord for the two central qubits can become minimized rapidly close to the critical point of a quantum phase transition. By considering the two qubits that are initially prepared in the Werner state, we study the evolution of the quantum discord and that of entanglement under the same conditions. Our results imply that entanglement can disappear completely after a finite time, while the quantum discord decreases and tends to be a stable value according to the initial-state parameter for a very-long-time interval. In this sense, the quantum discord is more robust than entanglement for the quantum system exposed to the environment. The relation between the quantum correlations and the classical correlation is also shown for two particular cases.

    This is yet another indispensable volume for all probabilists and collectors of the Saint-Flour series, and is also of great interest for mathematical physicists. It contains two of the three lecture courses given at the 32nd Probability Summer School in Saint-Flour (July 7-24, 2002). Boris Tsirelson's lectures introduce the notion of nonclassical noise produced by very nonlinear functions of many independent random variables, for instance singular stochastic flows or oriented percolation. Two examples are examined (noise made by a Poisson snake, the Brownian web). A new framework for the scaling limit is proposed, as well as old and new results about noises, stability, and spectral measures. Wendelin Werner's contribution gives a survey of results on conformal invariance, scaling limits and properties of some two-dimensional random curves. It provides a definition and properties of the Schramm-Loewner evolutions, computations (probabilities, critical exponents), the relation with critical exponents of planar...

  13. Simulating quantum correlations as a distributed sampling problem

    International Nuclear Information System (INIS)

    Degorre, Julien; Laplante, Sophie; Roland, Jeremie

    2005-01-01

    It is known that quantum correlations exhibited by a maximally entangled qubit pair can be simulated with the help of shared randomness, supplemented with additional resources, such as communication, postselection or nonlocal boxes. For instance, in the case of projective measurements, it is possible to solve this problem with protocols using one bit of communication or making one use of a nonlocal box. We show that this problem reduces to a distributed sampling problem. We give a new method to obtain samples from a biased distribution, starting with shared random variables following a uniform distribution, and use it to build distributed sampling protocols. This approach allows us to derive, in a simpler and unified way, many existing protocols for projective measurements, and extend them to positive operator value measurements. Moreover, this approach naturally leads to a local hidden variable model for Werner states

  14. American cinema and the construction of masculinity in film in the Federal Republic after 1945.

    Science.gov (United States)

    Leal, Joanne

    2012-01-01

    Since 1945, film in the Federal Republic has maintained an ambivalent relationship to American cinema and its embedded ideologies and nowhere is this more evident than in (West) German film's representations of masculinity. This article focuses on three historical moments when political and social shifts resulted in a problematising of male identities in the Federal Republic: the mid-1950s, the early 1970s and the late 1990s. Cinema responded to a perceived destabilisation of gender norms by exploring constructions of German masculinity in relation to the ambivalently received models of male identity offered by American cinema. With a detailed analysis of three specific examples – Georg Tressler's Die Halbstarken (1956), Rainer Werner Fassbinder's Der amerikanische Soldat (1970) and Fatih Akin's Kurz und schmerzlos (1998) – this article investigates the manner in which German cinema engages with these competing conceptions of masculinity and demonstrates the ways in which divergent understandings of gender identity can impact on representations of national and ethnic identity.

    Full Text Available The position about the internal connection between the cultural-historical theory of development of higher mental functions of L.S. Vygotsky and two prominent theories of the 20th century is substatianted. Firstly, this is the theory of conditioned reflex of I.P. Pavlov, including the idea of significant qualitative difference between human higher nervous activity and human behaviour and those of animals, due to the presence of the second signal system as a “grand speech signal” in humans. Second, this is the differential theory of development by H. Werner, which fits a number of key ideas of L.S. Vygotsky about the development of speech function and the role of the word in the psychological development of a child.

    CERN Document Server

    Pohl, Göran

    2015-01-01

    This book provides the readers with a timely guide to the application of biomimetic principles in architecture and engineering design. As a result of a combined effort by two internationally recognized authorities, the biologist Werner Nachtigall and the architect Göran Pohl, the book describes the principles which can be used to compare nature and technology, and at the same time it presents detailed explanations and examples showing how biology can be used as a source of inspiration and “translated” in building and architectural solutions (biomimicry). Even though nature cannot be directly copied, the living world can provide architects and engineers with a wealth of analogues and inspirations for their own creative designs. But how can analysis of natural entities give rise to advanced and sustainable design? By reporting on the latest bionic design methods and using extensive artwork, the book guides readers through the field of nature-inspired architecture, offering an extraordinary resource for pro...

  19. Farm Hall and the German atomic project of World War II a dramatic history

    CERN Document Server

    Cassidy, David C

    2017-01-01

    This gripping book brings back to life the events surrounding the internment of ten German Nuclear Scientists immediately after World War II. It is also an "eye-witness" account of the dawning of the nuclear age, with the dialogue and narrative spanning the period before, during and after atomic bombs were dropped on Japan at the end of the war. This pivotal historical episode is conveyed, along with the emotions as well as the facts, through drama, historical narrative, and photographs of the captive German nuclear scientists - who included Werner Heisenberg, Otto Hahn, and Max von Laue. The unique story that unfolds in the play is based on secretly recorded transcripts of the scientists’ actual conversations at Farm Hall, together with related documents and photographs.

    In this paper, Fisher information for an accelerated system initially prepared in the X-state is discussed. An analytical solution, which consists of three parts: classical, the average over all pure states and a mixture of pure states, is derived for the general state and for Werner state. It is shown that the Unruh acceleration has a depleting effect on the Fisher information. This depletion depends on the degree of entanglement of the initial state settings. For the X-state, for some intervals of Unruh acceleration, the Fisher information remains constant, irrespective to the Unruh acceleration. In general, the possibility of estimating the state’s parameters decreases as the acceleration increases. However, the precision of estimation can be maximized for certain values of the Unruh acceleration. We also investigate the contribution of the different parts of the Fisher information on the dynamics of the total Fisher information.

  3. Configuring the thermochemical hydrogen sulfuric acid process step for the Tandem Mirror Reactor

    This paper identifies the sulfuric acid step as the critical part of the thermochemical cycle in dictating the thermal demands and temperature requirements of the heat source. The General Atomic Sulfur-Iodine Cycle is coupled to a Tandem Mirror. The sulfuric acid decomposition process step is focused on specifically since this step can use the high efficiency electrical power of the direct converter together with the other thermal-produced electricity to Joule-heat a non-catalytic SO 3 decomposer to approximately 1250 0 K. This approach uses concepts originally suggested by Dick Werner and Oscar Krikorian. The blanket temperature can be lowered to about 900 0 K, greatly alleviating materials problems, the level of technology required, safety problems, and costs. A moderate degree of heat has been integrated to keep the cycle efficiency around 48%, but the number of heat exchangers has been limited in order to keep hydrogen production costs within reasonable bounds

    2005-01-01

    Cold fusion reactions are investigated with the goal to synthesize Z=118 isotopes with neutron numbers N=162, 168, 172, 176. Potential energy surfaces are calculated as the result of dynamic minimization with independent deformations of the target and projectile, small semi-axis of the projectile and distance between centers as degrees of freedom. An advanced binary macroscopic-microscopic method is used to obtain the deformation energy and the Werner-Wheeler approximation yield the mass tensor. Charge asymmetry is varied for the same mass asymmetry channel which belongs to a given energy valley. The highest penetrability values are obtained for cold fusion channels with Sn, Te and Xe isotopes as projectiles

    Bartel Leendert van der Waerden made major contributions to algebraic geometry, abstract algebra, quantum mechanics, and other fields. He liberally published on the history of mathematics. His 2-volume work Modern Algebra is one of the most influential and popular mathematical books ever written. It is therefore surprising that no monograph has been dedicated to his life and work. Van der Waerden’s record is complex. In attempting to understand his life, the author assembled thousands of documents from numerous archives in Germany, the Netherlands, Switzerland and the United States which revealed fascinating and often surprising new information about van der Waerden. Soifer traces Van der Waerden’s early years in a family of great Dutch public servants, his life as professor in Leipzig during the entire Nazi period, and his personal and professional friendship with one of the great physicists Werner Heisenberg. We encounter heroes and villains and a much more numerous group in between these two extremes. ...

  8. Local Hidden Variable Models for Entangled Quantum States Using Finite Shared Randomness

    2015-03-01

    The statistics of local measurements performed on certain entangled states can be reproduced using a local hidden variable (LHV) model. While all known models make use of an infinite amount of shared randomness, we show that essentially all entangled states admitting a LHV model can be simulated with finite shared randomness. Our most economical model simulates noisy two-qubit Werner states using only log2(12 )≃3.58 bits of shared randomness. We also discuss the case of positive operator valued measures, and the simulation of nonlocal states with finite shared randomness and finite communication. Our work represents a first step towards quantifying the cost of LHV models for entangled quantum states.

  10. [Psychiatry as cultural science: considerations following Max Weber].

    Science.gov (United States)

    Bormuth, M

    2010-11-01

    Psychiatry can be seen as a natural and cultural science. According to this the postulate of freedom is its strong value judgment. Since the times of enlightenment it has been described metaphorically by the myth of the expulsion from Paradise. Following Max Weber and Wilhelm Dilthey, Karl Jaspers has introduced this perspective into psychiatry. His strict dichotomy between explaining and understanding has later been critically revised by Werner Janzarik and Hans Heimann. Their concepts of structure dynamic, of pathography and of anthropology are closer to Max Weber who connected natural and cultural sciences in a much stronger way. Especially the pathographic example of Nietzsche allows to demonstrate the differences between Jaspers and the later psychopathologists of the Heidelberg and Tübingen schools.

    2006-04-01

    We have constructed a brand-new radiation hydrodynamics solver based upon Smoothed Particle Hydrodynamics, which works on a parallel computer system. The code is designed to investigate the formation and evolution of first-generation objects at z ≳ 10, where the radiative feedback from various sources plays important roles. The code can compute the fraction of chemical species e, H+, H, H-, H2, and H+2 by by fully implicit time integration. It also can deal with multiple sources of ionizing radiation, as well as radiation at Lyman-Werner band. We compare the results for a few test calculations with the results of one-dimensional simulations, in which we find good agreements with each other. We also evaluate the speedup by parallelization, which is found to be almost ideal, as long as the number of sources is comparable to the number of processors.

    2002-01-01

    The main interest in tropospheric volatile organic compounds (VOCs) originating from biogenic sources such as forests and anthropogenic sources such as cities is because these reactive trace gases can have a significant impact on levels of oxidants such as ozone (O 3 ) and the hydroxyl radical (OH). The proton-transfer-reaction mass-spectrometry (PTR-MS) technique developed by Werner Lindingers Laboratory, utilizes positive ion chemistry to measure trace neutral concentrations in air. It has been applied in food research, medicine and environmental studies to gain gas phase information about VOCs at parts per trillion (pptv) levels.The real-time method relies on proton transfer reactions between H 3 O + primary ions and VOCs which have a higher proton affinity than water molecules. Organic trace gases such as hydrocarbons, carbonyls, alcohols, acetonitrile, and others can be monitored on-line.Results on tropospheric VOCs measurements in tropical regions and in cities are discussed.

    We address the question as to whether an entangled state that satisfies local realism will give a violation of the same after entanglement swapping in a suitable scenario. We consider such a possibility as a kind of superadditivity in nonclassicality. Importantly, it will indicate that checking for violation of local realism, in the state obtained after entanglement swapping, can be a method for detecting entanglement in the input state of the swapping procedure. We investigate various entanglement swapping schemes, which involve mixed initial states. The strength of violation of local realism by the state obtained after entanglement swapping is compared with the one for the input states. We obtain a kind of superadditivity of violation of local realism for Werner states, consequent upon entanglement swapping involving Greenberger-Horne-Zeilinger-state measurements. We also discuss whether entanglement swapping of specific states may be used in quantum repeaters with a substantially reduced need to perform the entanglement distillation step

    Henri becquerel tracked down in 1896 a strange radiation, which was called radioactivity by Marie Curie. In the following centuries German scientists Max Planck, Albert Einstein and Werner Heisenberg presented fundamental contributions to understand processes in the atomic nucleus. At Goettingen, center of the international nuclear physics community, the American student J. Robert Oppenheimer admit to this physical research. In the beginning of 1939 the message of Otto Hahns' nuclear fission electrified researchers. The first step, unleashing atomic energy, was done. A half year later the Second World War begun. And suddenly being friend with and busily communicating physicians were devided into hostile power blocs as bearers of official secrets. The author tells in this exciting book the story of the first atomic bomb as a chain reaction of ideas, discoveries and visions, of friendships, jealousy and intrigues of scientists, adventurers and genius.

    2001-11-01

    Letters by Niels Bohr that have been kept secret since his death could explain the mystery of why Werner Heisenberg visited him in Copenhagen in 1941. When the author Michael Frayn spent two years writing Copenhagen, he had no idea how successful the play would become. He doubted that audiences would sit through a historical drama about a war-time meeting between Werner Heisenberg - head of Germany's nuclear programme - and his old mentor Niels Bohr in the Nazi-occupied Danish capital in 1941. But Frayn's efforts paid off. Audiences and critics alike have thrilled at the way the award-winning play probes the historical uncertainty that surrounds the encounter. Was Heisenberg fishing for information about the Allies' atomic plans - or was he trying to recruit Bohr for Germany's bomb programme? Did Heisenberg want to suggest that the Germans were close to finishing a bomb so that the Allies would make peace with Hitler? Maybe he was simply seeking approval from Bohr for his own atomic work. There is also a moral debate: did Heisenberg know how to build a bomb, but decided not to - or did he want to build one, but got his calculations wrong? Unfortunately, no-one was there to record or observe the encounter and we cannot know for sure what was said or implied between the two men. All we do know is that the pair dined together and took a short walk - and that the incident damaged Bohr and Heisenberg's friendship forever. To piece together what happened, historians of science have had to rely on Heisenberg's post-war recollections - which have been ambiguous and contradictory - along with scraps of evidence from secondary sources.

    Water is the main driver of ecosystem productivity in most terrestrial ecosystems worldwide. Extreme events are predicted to increase in frequency in many regions and dynamic responses in soil-vegetation-atmosphere feedbacks play a privotal role in understanding the ecosystem water balance and functioning. In this regard, more interdisciplinary approaches, bridging hydrology, ecophysiology and atmospheric sciences are needed and particularly water stable isotopes are a powerful tracer of water transfer in soils and at the soil-plant interface (Werner and Dubbert 2016). Here, we present observations 2 different ecosystems. Water fluxes, atmospheric concentrations and their isotopic compositions were measured using laser spectroscopy. Soil moisture and its isotopic composition in several depths as well as further water sources in the ecosystem were monitored throughout the year. Using these isotopic approaches we disentangled soil-plant-atmosphere feedback processes controlling the ecosystem water cycle including vegetation effects on soil water infiltration and distribution, event water use of vegetation and soil fluxes, vegetational soil water uptake depths plasticity and partitioning of ecosystem water fluxes. In this regard, we review current strategies of ET partitioning and highlight pitfalls in the presented strategies (Dubbert et al. 2013, Dubbert et al.2014a). We demonstrate that vegetation strongly influenced water cycling, altering infiltration and distribution of precipitation. In conclusion, application of stable water isotope tracers delivers a process based understanding of interactions between soil, understorey and trees governing ecosystem water cycling necessary for prediction of climate change impact on ecosystem productivity and vulnerability.

    Full Text Available The article “Karst aquifer recharge: Comments on ‘Characteristics of Point Recharge in Karst Aquifers’, by Adrian D. Werner, 2014, Water 6, doi:10.3390/w6123727” provides misrepresentation in some parts of Somaratne [1]. The description of Uley South Quaternary Limestone (QL as unconsolidated or poorly consolidated aeolianite sediments with the presence of well-mixed groundwater in Uley South [2] appears unsubstantiated. Examination of 98 lithological descriptions with corresponding drillers’ logs show only two wells containing bands of unconsolidated sediments. In Uley South basin, about 70% of salinity profiles obtained by electrical conductivity (EC logging from monitoring wells show stratification. The central and north central areas of the basin receive leakage from the Tertiary Sand (TS aquifer thereby influencing QL groundwater characteristics, such as chemistry, age and isotope composition. The presence of conduit pathways is evident in salinity profiles taken away from TS water affected areas. Pumping tests derived aquifer parameters show strong heterogeneity, a typical characteristic of karst aquifers. Uley South QL aquifer recharge is derived from three sources; diffuse recharge, point recharge from sinkholes and continuous leakage of TS water. This limits application of recharge estimation methods, such as the conventional chloride mass balance (CMB as the basic premise of the CMB is violated. The conventional CMB is not suitable for accounting chloride mass balance in groundwater systems displaying extreme range of chloride concentrations and complex mixing [3]. Over simplification of karst aquifer systems to suit application of the conventional CMB or 1-D unsaturated modelling as described in Werner [2], is not suitable use of these recharge estimation methods.

    vegetation strongly increased rain infiltration, specifically during strong rain events. In conclusion, beneficial understory vegetation effects were dominant. However, the observed vulnerability of the understory vegetation to drought and competition for water with trees suggests, that increased drought and altered precipitation pattern as predicted in future climate change scenarios for the Mediterranean basin not only threaten understory development. They also very likely decrease rain infiltration and ground water recharge by decreasing understory vegetation cover and increasing amount of heavy precipitation events with high run-off from sealed bare soils. This in turn can severely diminish cork-oak productivity and hence the resilience of the ecosystem toward drought (Costa e Silva et al., in rev.).

  4. SHARAD Constrains on Lava Flow Properties at Southeastern Utopia Planitia

    Science.gov (United States)

    Nunes, D. C.

    2012-12-01

    The volcanic flows originated at the southwestern flanks of Elysium Mons extend over 1,000 km into Utopia Planitia and overlie the knobby and polygonally cracked Vastitas Borealis Formation (VBF). These flows display rough and smooth lobate morphologies (RL and SL) morphologies and occur in conjunction with sinuous channels (SC). Russell and Head [2003] described these morphologies and hypothesized that RL correspond to debris flows that arose as lahars from the interaction between magma and ground water or ice. The mapping of Tanaka et al. [2003] identified these features similarly, attributing them to volcanoclastic flows formed from magma-volatile interactions. Crater counts by Werner et al. [2011] support surface ages between 1 and 2 Gyr for these flows. Analysis of the radargrams acquired throughout this area o show unambiguous subsurface reflectors that, individually, are relatively short and laterally intermittent. As a group, however, these reflectors are distributed sparsely over the flow field and correlate very well with the SL units. Delays to reflectors beneath the surface are generally in the order of < ~1 μs. In one locale with a high concentration of subsurface reflectors, centered at 117.61°E and 31.31°N, a sequence of smooth lobate flows overlie a smooth volcanic unit. The lobate flow in immediate contact with the smooth unit possesses subsurface reflections that correlate well with the flow edges, and where this flow is overlain by another lobate flow these reflections vanish. We interpret these reflections as a reflector that corresponds to the interface between the lobate flow and smooth unit. The average delay to this reflector is 0.68 - 0.71 μs along its length. The thickness of this lobate flow, estimated from MOLA elevation data, ranges between 35 and 40 m. The thickness estimate from MOLA and the delay to reflector from SHARAD together constrain the relative permittivity of the flow to between 6.5 and 9.5. These values are consistent

  5. Seawater intrusion vulnerability indicators for freshwater lenses in strip islands

    Morgan, L.; Werner, A. D.

    2014-12-01

    Freshwater lenses on small islands have been described as some of the most vulnerable aquifer systems in the world. Yet, little guidance is available regarding methods for rapidly assessing the vulnerability of freshwater lenses to the potential effects of climate change. To address this gap we employ a steady-state analytic modelling approach to develop seawater intrusion (SWI) vulnerability indicator equations. The vulnerability indicator equations quantify the propensity for SWI to occur in strip islands due to both recharge change and sea-level rise (SLR) (incorporating the effect of land surface inundation (LSI)). This work extends that of Werner et al. (2012) who developed SWI vulnerability indicator equations for unconfined and confined continental aquifers, and did not consider LSI. Flux-controlled and head-controlled conceptualisations of freshwater lenses are adopted. Under flux-controlled conditions the water table is able to rise unencumbered by land surface effects. Under head-controlled conditions the head is fixed at the centre of the lens due to, for example, centrally located topographic controls, surface water features or pumping. A number of inferences about SWI vulnerability in freshwater lenses can be made from the analysis: (1) SWI vulnerability indicators for SLR (under flux-controlled conditions) are proportional to lens thickness (or volume) and the rate of LSI and inversely proportional to island width; (2) SWI vulnerability indicators for recharge change (under flux-controlled conditions) are proportional to lens thickness (or volume) and inversely proportional to recharge; (3) SLR has greater impact under head-controlled conditions rather than flux-controlled conditions, whereas the opposite is the case for LSI and recharge change. Example applications to several case studies illustrate use of the method for rapidly ranking lenses according to vulnerability, thereby allowing for prioritisation of areas where further and more detailed SWI

    Attenuated vaccine strains of the alphaherpesvirus causing infectious laryngotracheitis of chickens (ILTV, gallid herpesvirus 1) can be used for mass application. Previously, we showed that live virus vaccination with recombinant ILTV expressing hemagglutinin of highly pathogenic avian influenza viruses (HPAIV) protected chickens against ILT and fowl plague caused by HPAIV carrying the corresponding hemagglutinin subtypes [Lüschow D, Werner O, Mettenleiter TC, Fuchs W. Protection of chickens from lethal avian influenza A virus infection by live-virus vaccination with infectious laryngotracheitis virus recombinants expressing the hemagglutinin (H5) gene. Vaccine 2001;19(30):4249-59; Veits J, Lüschow D, Kindermann K, Werner O, Teifke JP, Mettenleiter TC, et al. Deletion of the non-essential UL0 gene of infectious laryngotracheitis (ILT) virus leads to attenuation in chickens, and UL0 mutants expressing influenza virus haemagglutinin (H7) protect against ILT and fowl plague. J Gen Virol 2003;84(12):3343-52]. However, protection against H5N1 HPAIV was not satisfactory. Therefore, a newly designed dUTPase-negative ILTV vector was used for rapid insertion of the H5-hemagglutinin, or N1-neuraminidase genes of a recent H5N1 HPAIV isolate. Compared to our previous constructs, protein expression was considerably enhanced by insertion of synthetic introns downstream of the human cytomegalovirus immediate-early promoter within the 5'-nontranslated region of the transgenes. Deletion of the viral dUTPase gene did not affect in vitro replication of the ILTV recombinants, but led to sufficient attenuation in vivo. After a single ocular immunization, all chickens developed H5- or N1-specific serum antibodies. Nevertheless, animals immunized with N1-ILTV died after subsequent H5N1 HPAIV challenge, although survival times were prolonged compared to non-vaccinated controls. In contrast, all chickens vaccinated with either H5-ILTV alone, or H5- and N1-ILTV simultaneously, survived

    2017-04-01

    The photovoltaic reciprocity theory relates the electroluminescence spectrum of a solar cell under applied bias to the external photovoltaic quantum efficiency of the device as measured at short circuit conditions [1]. So far, the theory has been verified for a wide range of devices and material systems and forms the basis of a growing number of luminesecence imaging techniques used in the characterization of photovoltaic materials, cells and modules [2-5]. However, there are also some examples where the theory fails, such as in the case of amorphous silicon. In our contribution, we critically assess the assumptions made in the derivation of the theory and compare its predictions with rigorous formal relations as well as numerical computations in the framework of a comprehensive quantum-kinetic theory of photovoltaics [6] as applied to ultra-thin absorber architectures [7]. One of the main applications of the photovoltaic reciprocity relation is the determination of quasi-Fermi level splittings (QFLS) in solar cells from the measurement of luminescence. In nanostructure-based photovoltaic architectures, the determination of QFLS is challenging, but instrumental to assess the performance potential of the concepts. Here, we use our quasi-Fermi level-free theory to investigate existence and size of QFLS in quantum well and quantum dot solar cells. [1] Uwe Rau.

    The rapid recognition and repair of DNA damage is essential for the maintenance of genomic integrity and cellular survival. Multiple complex and interconnected DNA damage responses exist within cells to preserve the human genome, and these repair pathways are carried out by a specifi c interplay of protein-protein interactions. Thus a failure in the coordination of these processes, perhaps brought about by a breakdown in any one multifunctional repair protein, can lead to genomic instability, developmental and immunological abnormalities, cancer and premature aging. This study demonstrates a novel interaction between two such repair proteins, Xeroderma pigmentosum group G protein (XPG) and Werner syndrome helicase (WRN), that are both highly pleiotropic and associated with inherited genetic disorders when mutated. XPG is a structure-specifi c endonuclease required for the repair of UV-damaged DNA by nucleotide excision repair (NER), and mutations in XPG result in the diseases Xeroderma pigmentosum (XP) and Cockayne syndrome (CS). A loss of XPG incision activity results in XP, whereas a loss of non-enzymatic function(s) of XPG causes CS. WRN is a multifunctional protein involved in double-strand break repair (DSBR), and consists of 3’–5’ DNA-dependent helicase, 3’–5’ exonuclease, and single-strand DNA annealing activities. Nonfunctional WRN protein leads to Werner syndrome, a premature aging disorder with increased cancer incidence. Far Western analysis was used to map the interacting domains between XPG and WRN by denaturing gel electrophoresis, which separated purifi ed full length and recombinant XPG and WRN deletion constructs, based primarily upon the length of each polypeptide. Specifi c interacting domains were visualized when probed with the secondary protein of interest which was then detected by traditional Western analysis using the antibody of the secondary protein. The interaction between XPG and WRN was mapped to the C-terminal region of

    The conventional stable isotope ratios 13C/12C and 18O/16O in atmospheric CO2 are a powerful tool for unraveling the global carbon cycle. In recent years, it has been suggested that the abundance of the very rare isotopologue 13C18O16O on m/z 47 might be a promising tracer to complement conventional stable isotope analysis of atmospheric CO2 [Affek and Eiler, 2006; Affek et al. 2007; Eiler and Schauble, 2004; Yeung et al., 2009]. Here we present an automated analytical system that is designed for clumped isotope analysis of atmo- and biospheric CO2. The carbon dioxide gas is quantitatively extracted from about 1.5L of air (ATP). The automated stainless steel extraction and purification line consists of three main components: (i) a drying unit (a magnesium perchlorate unit and a cryogenic water trap), (ii) two CO2 traps cooled with liquid nitrogen [Werner et al., 2001] and (iii) a GC column packed with Porapak Q that can be cooled with liquid nitrogen to -30°C during purification and heated up to 230°C in-between two extraction runs. After CO2 extraction and purification, the CO2 is automatically transferred to the mass spectrometer. Mass spectrometric analysis of the 13C18O16O abundance is carried out in dual inlet mode on a MAT 253 mass spectrometer. Each analysis generally consists of 80 change-over-cycles. Three additional Faraday cups were added to the mass spectrometer for simultaneous analysis of the mass-to-charge ratios 44, 45, 46, 47, 48 and 49. The reproducibility for δ13C, δ18O and Δ47 for repeated CO2 extractions from air is in the range of 0.11o (SD), 0.18o (SD) and 0.02 (SD)o respectively. This automated CO2 extraction and purification system will be used to analyse the clumped isotopic signature in atmospheric CO2 (tall tower, Cabauw, Netherlands) and to study the clumped isotopic fractionation during photosynthesis (leaf chamber experiments) and soil respiration.

    Full Text Available A major medical challenge in the elderly is osteoporosis and the high risk of fracture. Telomere dysfunction is a cause of cellular senescence and telomere shortening, which occurs with age in cells from most human tissues, including bone. Telomere defects contribute to the pathogenesis of two progeroid disorders characterized by premature osteoporosis, Werner syndrome and dyskeratosis congenital. It is hypothesized that telomere shortening contributes to bone aging. We evaluated the skeletal phenotypes of mice with disrupted telomere maintenance mechanisms as models for human bone aging, including mutants in Werner helicase (Wrn−/−, telomerase (Terc−/− and Wrn−/−Terc−/− double mutants. Compared with young wild-type (WT mice, micro-computerized tomography analysis revealed that young Terc−/− and Wrn−/−Terc−/− mice have decreased trabecular bone volume, trabecular number and trabecular thickness, as well as increased trabecular spacing. In cortical bone, young Terc−/− and Wrn−/−Terc−/− mice have increased cortical thinning, and increased porosity relative to age-matched WT mice. These trabecular and cortical changes were accelerated with age in Terc−/− and Wrn−/−Terc−/− mice compared with older WT mice. Histological quantification of osteoblasts in aged mice showed a similar number of osteoblasts in all genotypes; however, significant decreases in osteoid, mineralization surface, mineral apposition rate and bone formation rate in older Terc−/− and Wrn−/−Terc−/− bone suggest that osteoblast dysfunction is a prominent feature of precocious aging in these mice. Except in the Wrn−/− single mutant, osteoclast number did not increase in any genotype. Significant alterations in mechanical parameters (structure model index, degree of anistrophy and moment of inertia of the Terc−/− and Wrn−/−Terc−/− femurs compared with WT mice were also observed.

    Fields of bedform patterns persist across many orders of magnitude, from cm-scale sub-aqueous current ripples to km-scale aeolian dunes, and form with surprisingly little difference in expression despite a range of formative environments. Because of the remarkable similarity between and among patterns, extracting information about climate and environment from these patterns is a challenge. For example, crest orientation is not diagnostic of a particular flow regime; similar patterns form under many different flow configurations. On Titan, these challenges have played out with many attempts to reconcile dune-field patterns with modeled and expected wind regimes. We propose that thinking about the change in dune orientation, rather than the orientation itself, can provide new insights on the long-term stability of the dune-field patterns and the formative wind regime. In this work, we apply the re-orientation model presented by Werner and Kocurek [Geology, 1997] to the equatorial dune fields of Titan. We measure variations in pattern parameters (crest spacing, crest length and defect density, which is the number of defect pairs per total crest length) both within and between Titan's dune fields to describe pattern maturity and identify areas where changes in dune orientation are likely to occur (or may already be occurring). Measured defect densities are similar to Earth's largest linear dune fields, such as the Namib Sand Sea and the Simpson Desert. We use measured defect densities in the Werner and Kocurek model to estimate crestline reorientation rates. We find reorientation timescales varying from ten to a hundred thousand times the average migration timescale (time to migrate a bedform one meter, ~1 Titan year according to Tokano (Aeolian Research, 2010)). Well organized patterns have the longest reorientation time scales (~10^5 migration timescales), while the topographically or spatially isolated patches of dunes show the shortest reorientation times (~10

    In 1974, at the Medical Policlinic of the University of Zürich, German-born physician-scientist Andreas Grüntzig (1939-1985) for the first time applied a balloon-tipped catheter to re-open a severely stenosed femoral artery, a procedure, which he initially called "percutaneous transluminal dilatation". Balloon angioplasty as a therapy of atherosclerotic vascular disease, for which Grüntzig and Charles T. Dotter (1920-1985) received a nomination for the Nobel Prize in Physiology or Medicine in 1978, became one of the most successful examples of translational medicine in the twentieth century. Known today as percutaneous transluminal angioplasty (PTA) in peripheral arteries or percutaneous transluminal coronary angioplasty (PTCA) or percutaneous coronary intervention (PCI) in coronary arteries, balloon angioplasty has become the method of choice to treat patients with acute myocardial infarction or occluded leg arteries. On the occasion of the 40(th) anniversary of balloon angioplasty, we summarize Grüntzig's life and career in Germany, Switzerland, and the United States and also review the developments in vascular medicine from the 1890s to the 1980s, including Dotter's first accidental angioplasty in 1963. The work of pioneers of catheterization, including Pedro L. Fariñas in Cuba, André F. Cournand in France, Werner Forssmann, Werner Porstmann and Eberhard Zeitler in Germany, António Egas Moniz and Reynaldo dos Santos in Portugal, Sven-Ivar Seldinger in Sweden, and Barney Brooks, Thomas J.

    The watercolor illusion is a long-range color assimilation (coloration effect) imparting a figure-ground segregation (figural effect) across large enclosed areas (B. Pinna, 1987; B. Pinna, G. Brelstaff, & L. Spillmann, 2001; B. Pinna, L. Spillmann, & J. S. Werner, 2003; B. Pinna, J. S. Werner, & L. Spillmann, 2003). The watercolored figure has a very poorly reversible or univocal figure-ground segregation and strongly enhances the unilateral belongingness of the boundaries (E. Rubin, 1915), a principle stating that the boundaries belong only to the figure and not to the background. The figural effect determines grouping and figure-ground segregation more strongly than the well-known Gestalt principles. Under watercolor conditions both the figure and the background assume new properties becoming respectively bulging object and hole both with a 3-D volumetric appearance (object-hole effect). Our purposes were: (i) to demonstrate that the hole induced by the watercolor illusion has unique figural properties comparable to those of the object and not present in the background induced by the known figure-ground principles; (ii) to demonstrate a dissociation of the object-hole effect from the coloration one; (iii) to demonstrate that the object-hole effect depends on a new principle. This was psychophysically tested by weakening (ungrouping) the whole figural organization of the watercolor illusion, i.e. by imparting motion to only some components of a stimulus, while other components remain stationary. The results showed that (i) subjects perceived moving holes more strongly than moving figures or objects enlarging and shrinking. (ii) Paradoxically, moving holes appear more as figures than the bulging surfaces. (iii) When motion was imparted to components that while stationary were perceived as objects, their figurality is further enhanced (summation effect). (iv) When object-hole and coloration effects were dissociated no significant difference compared to illusory

The CERN Antiproton Decelerator decelerates antipro-tons emerging from a target placed in the path of a 26 GeV/c proton beam from 90 % of to about 10 % of the speed of light. However, even this is far too fast for many of the most interesting experiments on antiprotons planned by Danish and Japanese members of the ASACUSA collaboration.

    WRN is unique among the five human RecQ DNA helicases by having a functional exonuclease domain (WRN-exo) and being defective in the premature aging and cancer-related disorder Werner syndrome. Here, we characterize WRN-exo crystal structures, biochemical activity and participation in DNA end-joining. Metal ion complex structures, active site mutations and activity assays reveal a two-metal-ion mediated nuclease mechanism. The DNA end-binding Ku70/80 complex specifically stimulates WRN-exo activity, and structure-based mutational inactivation of WRN-exo alters DNA end-joining in human cells. We furthermore establish structural and biochemical similarities of WRN-exo to DnaQ family replicative proofreading exonucleases, with WRN-specific adaptations consistent with dsDNA specificity and functionally important conformational changes. These results indicate WRN-exo is a human DnaQ family member and support analogous proof-reading activities that are stimulated by Ku70/80 with implications for WRN functions in age related pathologies and maintenance of genomic integrity.

    We have developed a semi-analytic framework to model the large-scale evolution of the first Population III (Pop III) stars and the transition to metal-enriched star formation. Our model follows dark matter halos from cosmological N-body simulations, utilizing their individual merger histories and three-dimensional positions, and applies physically motivated prescriptions for star formation and feedback from Lyman-Werner (LW) radiation, hydrogen ionizing radiation, and external metal enrichment due to supernovae winds. This method is intended to complement analytic studies, which do not include clustering or individual merger histories, and hydrodynamical cosmological simulations, which include detailed physics, but are computationally expensive and have limited dynamic range. Utilizing this technique, we compute the cumulative Pop III and metal-enriched star formation rate density (SFRD) as a function of redshift at z ≥ 20. We find that varying the model parameters leads to significant qualitative changes in the global star formation history. The Pop III star formation efficiency and the delay time between Pop III and subsequent metal-enriched star formation are found to have the largest impact. The effect of clustering (i.e. including the three-dimensional positions of individual halos) on various feedback mechanisms is also investigated. The impact of clustering on LW and ionization feedback is found to be relatively mild in our fiducial model, but can be larger if external metal enrichment can promote metal-enriched star formation over large distances.
