Full Text Available La era de la comunicación en cambio constante que vivimos ha obligado a las marcas a redefinir sus estrategias comunicativas y publicitarias, especialmente cuando se trata de tener presencia en plataformas digitales. Conscientes de que actualmente necesitan contar historias (storytelling más allá de las ventajas y bondades de sus productos yservicios (la economía del cariño, las empresas diseñan estrategias basadas en narraciones audiovisuales ficcionales, buscando presentar a la marca de manera cercanay transparente y conectar así con la audiencia (engagement, desde un enfoque inspirado en el profundo conocimiento del público destinatario y de su relación con las marcas (big data, basado en la transmedialidad de los contenidos y buscando la viralidad, gracias a la interacción de los usuarios.Venimos asistiendo a una inclinación creciente de las marcas por generar contenidos denominados Branded Content, inspirados en las teorías de la narrativa transmediática,y ejemplo de la disrupción con los clásicos modelos publicitarios. Esta tendencia se evidencia de manera más destacada en aquellas marcas enfocadas al público adolescente, una generación (llamada Generación Z o iGen especialmente permeable a la era de la comunicación en cambio; jóvenes multitaskers que han crecido con las plataformas digitales y que son más exigentes con las empresas.Por otra parte, las plataformas digitales han fomentado un nuevo concepto de la clásica figura del prescriptor publicitario. Se trata del influencer, en muchas ocasiones un personaje famoso (celebrity, con gran poder de recomendación e influencia, que comparte con sus seguidores en redes sociales sus experiencias con las marcas.Especialmente sensible a estas recomendaciones es el público adolescente, heavy users de las redes sociales que utilizan estos espacios, entre otras actividades, para seguir a sus ídolos e interactuar con ellos.En el presente artículo se

Novel Antimicrobial Peptides EeCentrocins 1, 2 and EeStrongylocin 2 from the Edible Sea Urchin Echinus esculentus Have 6-Br-Trp Post-Translational Modifications.

Directory of Open Access Journals (Sweden)

Full Text Available The global problem of microbial resistance to antibiotics has resulted in an urgent need to develop new antimicrobial agents. Natural antimicrobial peptides are considered promising candidates for drug development. Echinoderms, which rely on innate immunity factors in the defence against harmful microorganisms, are sources of novel antimicrobial peptides. This study aimed to isolate and characterise antimicrobial peptides from the Edible sea urchin Echinus esculentus. Using bioassay-guided purification and cDNA cloning, three antimicrobial peptides were characterised from the haemocytes of the sea urchin; two heterodimeric peptides and a cysteine-rich peptide. The peptides were named EeCentrocin 1 and 2 and EeStrongylocin 2, respectively, due to their apparent homology to the published centrocins and strongylocins isolated from the green sea urchin Strongylocentrotus droebachiensis. The two centrocin-like peptides EeCentrocin 1 and 2 are intramolecularly connected via a disulphide bond to form a heterodimeric structure, containing a cationic heavy chain of 30 and 32 amino acids and a light chain of 13 amino acids. Additionally, the light chain of EeCentrocin 2 seems to be N-terminally blocked by a pyroglutamic acid residue. The heavy chains of EeCentrocins 1 and 2 were synthesised and shown to be responsible for the antimicrobial activity of the natural peptides. EeStrongylocin 2 contains 6 cysteines engaged in 3 disulphide bonds. A fourth peptide (Ee4635 was also discovered but not fully characterised. Using mass spectrometric and NMR analyses, EeCentrocins 1 and 2, EeStrongylocin 2 and Ee4635 were all shown to contain post-translationally brominated Trp residues in the 6 position of the indole ring.

The branching fraction of the rate decay $B^0 \\rightarrow K^{*0}e^+e^-$ in the dilepton mass region from 30 to 1000 MeV$/c^2$ has been measured by the LHCb experiment, using $pp$ collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, at a centre-of-mass energy of 7 TeV. The decay mode $B^0 \\rightarrow J/\\psi(e^+e^-) K^{*0}$ is utilized as a normalization channel. The branching fraction $B^0 \\rightarrow K^{*0}e^+e^-$ is measured to be $$ B(B^0 \\rightarrow K^{*0}e^+e^-)^{30-1000 MeV/c^2}= (3.1\\, ^{+0.9\\mbox{} +0.2}_{-0.8\\mbox{}-0.3} \\pm 0.2)\\times 10^{-7}, $$ where the first error is statistical, the second is systematic, and the third comes from the uncertainties on the $B^0 \\rightarrow J/\\psi K^{*0}$ and $J/\\psi \\rightarrow e^+e^- $ branching fractions.

Full Text Available OBJETIVO: Determinar la utilidad de una plataforma educativa tipo Moodle para el desarrollo del conocimiento en residentes de la especialidad de urgencias médico-quirúrgicas (UMQ. MÉTODOS: Estudio cuasiexperimental que comparó los resultados en las evaluaciones departamentales de los residentes de la especialidad de UMQ de dos unidades hospitalarias mexicanas, posterior a desarrollar sus actividades académicas con diferentes estrategias educativas. El grupo control desarrolló actividades de forma tradicional (sesiones magistrales, discusión dirigida, mientras que el grupo comparativo realizó actividades en plataforma tipo Moodle, a través de diferentes recursos (foros, chats, wikis, subida de archivos. Se empleó estadística no paramétrica. El estudio fue realizado en los ciclos académicos 2010 - 2011 y 2011 - 2012, disponiéndose de tres versiones del curso en línea según el grado académico de los residentes (primero, segundo o tercer año. RESULTADOS: Se encontraron diferencias estadísticamente significativas en las evaluaciones de mitad de ciclo académico, las cuales registraron un incremento en las evaluaciones de fin de ciclo, principalmente en los residentes de tercer año. En ambos ciclos académicos, las evaluaciones de mitad de ciclo informaron que solo un residente del grupo control se ubicó en el rango medio, mientras que la mayoría lo hizo en los rangos bajos. Los recursos más utilizados dentro de la plataforma Moodle fueron la subida de archivos (77% y el foro (63%. El 46,4% de los residentes refirieron algún tipo de limitación al momento de emplear la plataforma, siendo la principal la falta de tiempo (76,9%. CONCLUSIONES: El empleo de una plataforma educativa tipo Moodle parece ser de utilidad y tener mayores alcances en el desarrollo de conocimientos en comparación con las estrategias tradicionales. Se recomienda implementar estrategias educativas apoyadas en plataformas tipo Moodle tanto en la especialidad

Relativistic corrections to exclusive χc J+γ production from e+e- annihilation

2018-05-01

We calculate in the nonrelativistic QCD (NRQCD) factorization framework all leading relativistic corrections to the exclusive production of χc J+γ in e+e- annihilation. In particular, we compute for the first time contributions induced by octet operators with a chromoelectric field. The matching coefficients multiplying production long distance matrix elements (LDMEs) are determined through perturbative matching between QCD and NRQCD at the amplitude level. Technical challenges encountered in the nonrelativistic expansion of the QCD amplitudes are discussed in detail. The main source of uncertainty comes from the not so well known LDMEs. Accounting for it, we provide the following estimates for the production cross sections at √{s }=10.6 GeV : σ (e+e-→χc 0+γ )=(1.4 ±0.3 ) fb , σ (e+e-→χc 1+γ )=(15.0 ±3.3 ) fb , and σ (e+e-→χc 2+γ )=(4.5 ±1.4 ) fb .

Full Text Available A corrosão é uma das principais causas de falhas em equipamentos e tubulações de plataformas de produção de petróleo. Essas falhas prejudicam o processo, atrasam o cronograma operacional de produção, geram altos custos de manutenção, além de gerar riscos à saúde e ao meio-ambiente. Devido ao fato de que a maioria dos equipamentos, tubulações e dutos das plataformas de produção são constituídos de aço (em geral, aço carbono, a indústria de exploração de petróleo estará sempre convivendo com os processos corrosivos. A utilização de um plano de monitoração da corrosão para diagnosticar, controlar e gerenciar a evolução dos processos corrosivos nas plataformas é a estratégia de ação proposta nesse trabalho. O Plano de Monitoração da Corrosão Interna (PMCI se baseia na análise laboratorial da corrosividade de fluídos e resíduos coletados periodicamente nos sistemas das plataformas de operação; na taxa de corrosão determinada pela utilização periódica de cupons instalados nas tubulações dos sistemas das plataformas, como cupons de perda de massa e sondas de resistência elétrica; e finalmente, na coleta periódica de dados operacionais obtidos durante a operação dos sistemas das plataformas. O PMCI irá direcionar e gerenciar as ações a serem tomadas no caso de um agravamento de um processo corrosivo, identificando dos mecanismos corrosivos e sua localização nos diversos sistemas das plataformas. A otimização do uso de inibidores de corrosão e outros produtos químicos é uma das principais vantagens do PMCI.

Plataformas marítimas para recreo

Full Text Available At Scheveningen, in Holland, a number of platforms over the sea have been recently set up. These platforms, or piers, constitute a set of recreational units. Each of these platforms, three in number, has a specific function, which is strictly sporting and recreational. One of them is a solarium, another is a fishing base, and the third a restaurant. Each of them is a fine viewpoint towards the sea and the coast. The section of the beach where these platforms are situated is bordered by a great maritime avenue, along which several hotels, amusement establishments and residential blocks are located. Access to these platforms is along a pier consisting of prestressed concrete portal frames. The partial structures making up these platforms have been carefully designed. Various constructional methods were initially proposed, including metallic and timber ones, but prestressed concrete was finally chosen as being the cheapest. The structure consists of a series of columns supporting a flooring deck with reinforcing members, of conventional design. Along the southern part of the United Kingdom there are various seaside piers, but their function is not strictly recreational nor a vantage point to watch the sea: they rather serve various aspects of daily life, which require moments of leisure. It was in this sense that the original project of these platforms was envisaged.Se ha construido recientemente, en Scheveningen, Holanda, una serie de plataformas enclavadas en el mar, con su correspondiente acceso, que constituye un conjunto variado de recreos. Cada, una de estas tres plataformas tiene su misión específica, meramente recreativa: solario, pesca y restaurante. Todas ellas son verdaderos miradores hacia el mar o costa. La zona de playa en la que están situadas las plataformas está bordeada por una gran avenida o paseo marítimo, donde se encuentran varios hoteles, lugares de recreo y bloques residenciales.

Full Text Available This article analyzes the different building stages of three large sea platforms. After studying the structure's main characteristics, preparing scale models and calculating ail the elements, platform construction was carried out in three stages: — Dry-dock construction of the hull base. — Installation in the water and finishing the structure. — Immersion and bridge installation. Finally, the necessary operations to move the platform to its definite location were carried out. The structures are formed by a parallelepiped hull of reinforced concrete, divided into compartments by means of vertical orthogonals panels on top of which 2 or 4 piles are placed to support the bridge.

Full Text Available Using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e+e−→γISRX(3872→γISRπ+π−J/ψ via the Initial State Radiation technique. The production of a resonance with quantum numbers JPC=1++ such as the X(3872 via single photon e+e− annihilation is forbidden, but is allowed by a next-to-leading order box diagram. We do not observe a significant signal of X(3872, and therefore give an upper limit for the electronic width times the branching fraction ΓeeX(3872B(X(3872→π+π−J/ψ<0.13 eV at the 90% confidence level. This measurement improves upon existing limits by a factor of 46. Using the same final state, we also measure the electronic width of the ψ(3686 to be Γeeψ(3686=2213±18stat±99sys eV.

Using data samples collected at center-of-mass energies of √s = 4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a search for the process e+e- → γχcJ (J=0, 1, 2) and find evidence for e+e- → γχc1 and e+e- → γχc2 with statistical significances of 3.0σ and 3.4σ, respectively. The Born cross sections σB(e+e- → γχcJ), as well as their upper limits at the 90% confidence level (C.L.) are determined at each center-of-mass energy.

Spectrometer requirements for (e,e'2N) studies

International Nuclear Information System (INIS)

Lightbody, J.W. Jr.

1981-01-01

One specific experiment that may be performed with a future CW accelerator is a study of (e,e'2N) reactions through which we may learn details of the short range interaction of two nucleons within nuclear matter. It is suspected that the only mechanism which can lead to the observed high momentum components in the single nucleon momentum distribution (above approx. 400 MeV/c) inferred from (e,e'p) and (γ,p) measurements is the presence of short-range few-body correlations in the many-body nuclear wave function. It is expected that the explicit pair correlation function may be inferred from relative two-nucleon momentum distributions measured in (e,e'2N) experiments. It is therefore interesting to estimate counting rates using measured one-body momentum distributions to see what types of spectrometers are required

Occurrence of 17α-ethynylestradiol (EE2) in the environment and effect on exposed biota: a review.

Science.gov (United States)

Aris, Ahmad Zaharin; Shamsuddin, Aida Soraya; Praveena, Sarva Mangala

2014-08-01

17α-ethynylestradiol (EE2) is a synthetic hormone, which is a derivative of the natural hormone, estradiol (E2). EE2 is an orally bio-active estrogen, and is one of the most commonly used medications for humans as well as livestock and aquaculture activity. EE2 has become a widespread problem in the environment due to its high resistance to the process of degradation and its tendency to (i) absorb organic matter, (ii) accumulate in sediment and (iii) concentrate in biota. Numerous studies have reported the ability of EE2 to alter sex determination, delay sexual maturity, and decrease the secondary sexual characteristics of exposed organisms even at a low concentration (ng/L) by mimicking its natural analogue, 17β-estradiol (E2). Thus, the aim of this review is to provide an overview of the science regarding EE2, the concentration levels in the environment (water, sediment and biota) and summarize the effects of this compound on exposed biota at various concentrations, stage life, sex, and species. The challenges in respect of EE2 include the extension of the limited database on the EE2 pollution profile in the environment, its fate and transport mechanism, as well as the exposure level of EE2 for better prediction and definition revision of EE2 toxicity end points, notably for the purpose of environmental risk assessment.

The FCC-ee is a proposed circular e+e- collider installed in a new 100 km tunnel delivering high luminosity to four experiments at centre-of-mass energies ranging from 91 GeV (Z pole) over 160 GeV (W threshold) and 240 GeV (H production) to 350 GeV (t physics). The FCC-ee design is pursued as part of the global Future Circular Collider (FCC) study, which regards the FCC-ee as a potential intermediate step towards a 100-TeV hadron collider, called FCC-hh, sharing the same tunnel infrastructure. We here report the FCC-ee design status.

Using 4.479×10^{8}  ψ(3686) events collected with the BESIII detector, we search for the decays ψ(3686)→e^{+}e^{-}χ_{cJ} and χ_{cJ}→e^{+}e^{-}J/ψ, where J=0, 1, 2. The decays ψ(3686)→e^{+}e^{-}χ_{cJ} and χ_{cJ}→e^{+}e^{-}J/ψ are observed for the first time. The measured branching fractions are B(ψ(3686)→e^{+}e^{-}χ_{cJ})=(11.7±2.5±1.0)×10^{-4}, (8.6±0.3±0.6)×10^{-4}, (6.9±0.5±0.6)×10^{-4} for J=0, 1, 2, and B(χ_{cJ}→e^{+}e^{-}J/ψ)=(1.51±0.30±0.13)×10^{-4}, (3.73±0.09±0.25)×10^{-3}, (2.48±0.08±0.16)×10^{-3} for J=0, 1, 2, respectively. The ratios of the branching fractions B(ψ(3686)→e^{+}e^{-}χ_{cJ})/B(ψ(3686)→γχ_{cJ}) and B(χ_{cJ}→e^{+}e^{-}J/ψ)/B(χ_{cJ}→γJ/ψ) are also reported. Also, the α values of helicity angular distributions of the e^{+}e^{-} pair are determined for ψ(3686)→e^{+}e^{-}χ_{c1,2} and χ_{c1,2}→e^{+}e^{-}J/ψ.

Direct measurement of α_Q_E_D(m_Z"2) at the FCC-ee

International Nuclear Information System (INIS)

Janot, Patrick

2016-01-01

When the measurements from the FCC-ee become available, an improved determination of the standard-model “input' parameters will be needed to fully exploit the new precision data towards either constraining or fitting the parameters of beyond-the-standard-model theories. Among these input parameters is the electromagnetic coupling constant estimated at the Z mass scale, α_Q_E_D(m_Z"2). The measurement of the muon forward-backward asymmetry at the FCC-ee, just below and just above the Z pole, can be used to make a direct determination of α_Q_E_D(m_Z"2) with an accuracy deemed adequate for an optimal use of the FCC-ee precision data.

1991-01-01

The reasons for the search of CP violation in hyperon decays are briefly described reviewing the observables experimentally used both in p anti p and in e+e- machines. The expected rates of lambda anti lambda events produced in the J/PSI resonance at the tau c F are presented, showing the possibility of reaching the level of sensitivity at which CP violation effects may occur, according to the STANDARD MODEL. Some considerations for the design of the tau c F accelerator and detector are presented. (author)

The ALICE Collaboration at the LHC has measured the $J/\\psi$ and $\\psi$' photoproduction at mid-rapidity in ultra-peripheral Pb-Pb collisions at $\\sqrt{s_{NN}}$ = 2.76 TeV. The charmonium is identified via its leptonic decay for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 23 ${\\mu}b^{-1}$. The cross section for coherent and incoherent $J/\\psi$ production in the rapidity interval -0.9 < y < 0.9, are $d\\sigma_{J/\\psi}^{coh}/dy = 2.38^{+0.34}_{-0.24}(sta+sys)$ mb and $d\\sigma_{J/\\psi}^{inc}/dy = 0.98^{+0.19}_{-0.17}(sta+sys)$ mb, respectively. The results are compared to theoretical models for $J/\\psi$ production and the coherent cross section is found to be in good agreement with those models which include nuclear gluon shadowing consistent with EPS09 parametrization. In addition the cross section for the process $\\gamma\\gamma \\to e^+e^-$ has been measured and found to be in agreement with the STA...

Menke, S

2001-01-01

It has been shown in recent analyses by ALEPH [1] and OPAL [2] that precision QCD tests are possible with hadronic tau decays by comparing spectral moments of the hadronic decay ratio of the tau with QCD calculations. In principle e+e- data can be used in a similar manner by evaluating spectral moments of R. The current e+e- data is compared with the OPAL tau data and a prediction is made on the achievable accuracy of QCD tests with the projected precision of PEP-N [3].

17α-Ethinylestradiol (EE2) effect on global gene expression in primary rainbow trout (Oncorhynchus mykiss) hepatocytes

Hultman, Maria T.; Song, You; Tollefsen, Knut Erik

Highlights: • EE2 induced large scale transcriptional changes in primary hepatocytes. • Classical estrogen biomarkers were altered in a concentration-dependent manner. • EE2 altered biological processes related to lipid transport and reproduction. • EE2 interfered with lipid metabolism, biotransformation, and multidrug transport. • In vitro transcriptional changes were fairly similar to that observed in vivo. - Abstract: The potential impact of endocrine disrupting chemicals (EDCs) in the aquatic environment has driven the development of screening assays to evaluate the estrogenic properties of chemicals and their effects on aquatic organisms such as fish. However, obtaining full concentration–response relationships in animal (in vivo) exposure studies are laborious, costly and unethical, hence a need for developing feasible alternative (non-animal) methods. Use of in vitro bioassays such as primary fish hepatocytes, which retain many of the native properties of the liver, has been proposed for in vitro screening of estrogen receptor (ER) agonists and antagonists. The aim of present study was to characterize the molecular mode of action (MoA) of the ER agonist 17α-ethinylestradiol (EE2) in primary rainbow trout (Oncorhynchus mykiss) hepatocytes. A custom designed salmonid 60,000-feature (60k) oligonucleotide microarray was used to characterize the potential MoAs after 48 h exposure to EE2. The microarray analysis revealed several concentration-dependent gene expression alterations including classical estrogen sensitive biomarker gene expression (e.g. estrogen receptor α, vitellogenin, zona radiata). Gene Ontology (GO) analysis displayed transcriptional changes suggesting interference of cellular growth, fatty acid and lipid metabolism potentially mediated through the estrogen receptor (ER), which were proposed to be associated with modulation of genes involved in endocrine function and reproduction. Pathway analysis supported the identified GOs and

Full Text Available El documento presenta las oportunidades que dentro del contexto de disponibilidad de mercado existen para el uso de las plataformas open data, ya que no todas las organizaciones tienen recursos propios que sean suficientes para implantar sus plataformas desde una base inicial, siendo por lo tanto necesario requerir aquellas que han sido desarrolladas por empresas expertas en ello; si se considera tomar ésta opción tendrían a resolver el proceso, sin embargo podría constituirse en una pérdida de capacidad de llegar a personalizar y adecuar integralmente la plataforma a las necesidades especificas de la organización que las requiera. Tomando en consideración lo expuesto, en este artículo de revisión se detallan características con las que cuentan  algunas de las plataformas consideradas principales por su aplicabilidad que están disponibles en el mercado, sea a través de un modelo de software gratuito o libre y, también,  con licencia comercial, en otros casos. Los datos que han sido considerados para este análisis se los referencia con respecto a la información que los propios proveedores han proporcionado por medio de documentación que se encuentra publicada por ellos  en la web, como también se ha considerado la experiencia con versiones trial y ejemplos utilizables de manera abierta.   Abstract   The paper presents the opportunities within the context of market availability exist for the use of open data platforms, since not all organizations have their own resources which are sufficient to implement their platforms from an initial base, being therefore necessary to require those that have been developed by expert companies in it; considering taking this option would solve the process, however it could become a loss of ability to reach fully customize and adapt the platform to the specific needs of the organization that requires them.

Full Text Available La utilización de plataformas vibratorias se ha extendido en los ámbitos deportivo y clínico. Sin embargo, son escasos los trabajos sobre su correcta utilización y seguridad. En este estudio transversal se registró, en 22 sujetos sanos (23,7 ± 3,7 años, talla 1,75 ± 0,08 m, masa 71,63 ± 14,5 kg con un nivel de actividad física bajo/medio, la aceleración en el eje vertical en la cabeza durante la posición de bipedestación sobre una plataforma vibratoria, en tres angulaciones distintas (180º, 150º y 120º, a tres frecuencias de vibración (5, 16 y 27 Hz y a una amplitud constante (3 mm. El objetivo del estudio fue valorar la influencia de la posición de la rodilla sobre la transmisión de vibraciones desde la plataforma hasta la cabeza. Los resultados indican que la amortiguación de la vibración aumentó con cada incremento en el grado de flexión de la rodilla, siendo la influencia de la posición articular tanto más relevante cuanto mayor fue la frecuencia de vibración de la plataforma (p <0.001. Estos resultados sugieren que para la realización segura de ejercicios en bipedestación sobre plataforma vibratoria a intensidades altas debe evitarse la extensión completa de rodilla.

Spiral correlations in frustrated one-dimensional spin-1/2 Heisenberg J1-J2-J3 ferromagnets

International Nuclear Information System (INIS)

Zinke, R; Richter, J; Drechsler, S-L

2010-01-01

We use the coupled cluster method for infinite chains complemented by exact diagonalization of finite periodic chains to discuss the influence of a third-neighbor exchange J 3 on the ground state of the spin- 1/2 Heisenberg chain with ferromagnetic nearest-neighbor interaction J 1 and frustrating antiferromagnetic next-nearest-neighbor interaction J 2 . A third-neighbor exchange J 3 might be relevant to describe the magnetic properties of the quasi-one-dimensional edge-shared cuprates, such as LiVCuO 4 or LiCu 2 O 2 . In particular, we calculate the critical point J 2 c as a function of J 3 , where the ferromagnetic ground state gives way for a ground state with incommensurate spiral correlations. For antiferromagnetic J 3 the ferro-spiral transition is always continuous and the critical values J 2 c of the classical and the quantum model coincide. On the other hand, for ferromagnetic J 3 ∼ 1 | the critical value J 2 c of the quantum model is smaller than that of the classical model. Moreover, the transition becomes discontinuous, i.e. the model exhibits a quantum tricritical point. We also calculate the height of the jump of the spiral pitch angle at the discontinuous ferro-spiral transition.

Study of CP violation in the channel Bd0 → J/ψ(ee)KS0, identification and reconstruction of electrons in the LHCb experiment

International Nuclear Information System (INIS)

Terrier, H.

2005-04-01

LHCb experiment has been designed in order to do precise measurements of CP violation and rare decays with B mesons. In 2000, the collaboration decided to modify the spectrometer in order to minimize the amount of matter seen by particles and to optimize the trigger. This thesis was done in this context and is divided into 3 parts. The first part is relative to the electron identification and to the recovery of Bremsstrahlung photons emitted by electrons when they pass through matter. Electron identification is mainly based on information provided by calorimeter system but also uses RICH and muon system. A method based on reference histograms had been developed which combine information provided by these detectors. Electron identification efficiency, for electrons in ECAL acceptance is 95% and the pion mis-identification rates 0.8% with a 65% purity of electron sample. Bremsstrahlung recovery allows the selection of J/φ decaying in e + e - pair and of B d 0 → J/φ(ee)K S 0 channel which are described in the second part. The selection of this channel was developed in order to get an acceptable selection efficiency with a good rejection of background. A set of kinematic and topological cuts were designed and total selection efficiency is 0.176%, corresponding to 28000 untagged events reconstructed by year, with a ratio B/S belonging to [0.017;0.069] (at 90% of confidence level) for inclusive bb-bar background. In the third part, B meson flavour tagging is presented. The addition of information provided by the vertex locator allows to reject electron coming from conversion and to improve slightly the performances. The LHCb sensibility to sin(2β) from B 0 → J/ψK S 0 decay is also determined. The statistical error, expected after one year of data collecting, corresponding to an integrated luminosity of 2 fb -1 and bb-bar pair cross section of 0.5 mb, varies from 0.015 to 0.020 according to the values of sin(2β), |λ f | and B/S.

Full Text Available INTRODUÇÃO: Poucos estudos correlacionaram as medidas de equilíbrio entre os principais testes funcionais e a plataforma de força em atletas. OBJETIVO: Determinar a relação entre três testes funcionais de equilíbrio com as principais medidas da plataforma de força em atletas. MÉTODO: Quinze atletas do sexo feminino praticantes de futebol de salão (futsal e handebol, com idades entre 13 a 17 anos participaram do estudo. As atletas realizaram três testes funcionais: 1 Star excursion balance test, 2 Salto lateral e 3 Figura em oito; além de um teste em apoio unipodal sobre uma plataforma de força com os olhos abertos durante 30 segundos. Os parâmetros do centro de pressão dos pés (COP foram calculados por análise estabilográfica. Para todos os testes (funcionais e plataforma, três tentativas foram realizadas e a média foi retida para as análises. RESULTADOS: As correlações entre os testes funcionais e a plataforma de força foram de r = 0,01 a -0,69 (fraca a moderada, dependendo da variável do COP. As melhores correlações (r = -0,69 foram encontradas entre o Star Excursion Balance Test de alcance e a área do COP, indicando que quanto maior a distância alcançada, melhor o equilíbrio. Segundo, uma correlação de fraca a moderada foi encontrada entre o teste da figura em oito e a área do COP (p. ex: r = 0.43. O teste de salto lateral não apresentou boa correlação com os obtidos na plataforma de força. CONCLUSÃO: Este estudo demonstrou que para a avaliação do equilíbrio em atletas de futsal e handebol feminino o teste Star Excursion Balance Test pode ser usados na ausência da plataforma de força para identificação de possíveis déficits de equilíbrio.

Beam Dynamics Challenges for FCC-ee

The goals of FCC-ee include reaching luminosities of up to a few 1036 cm-2s-1 per interaction point at the Z pole or some 1034 cm-2s-1 at the ZH production peak, and pushing the beam energy up to ≥175 GeV, in a ring of 100 km circumference, with a total synchrotron-radiation power not exceeding 100 MW. A parameter baseline as well as high-luminosity crab-waist options were described in [1] and [2], respectively. The extremely high luminosity and resulting short beam lifetime (due to radiative Bhabha scattering) are sustained by top-up injection. The FCC-ee design status and typical beam parameters for different modes of operation are reported in [3]. One distinct feature of the FCC-ee design is its conception as a double ring, with separate beam pipes for the two counter-rotating (electron and positron) beams, resembling, in this aspect, the high-luminosity B factories PEP-II, KEKB and SuperKEKB as well as the LHC. The two separate rings do not only permit operation with a large number of bunches, up to a f...

The frustrated spin-1/2 J 1 -J 2 -J 3 antiferromagnet with exchange anisotropy on the two-dimensional square lattice is investigated. The exchange anisotropy is presented by η with 0 ≤ η J 1 , J 2 , J 3 and anisotropy on the possible phase transition of the Néel state and collinear state are studied comprehensively. Our results indicate that for J 3  > 0 there are upper limits [Formula: see text] and η c values. When 0 J 3  ≤ [Formula: see text] and 0 ≤ η ≤ η c , the Néel and collinear states have the same order-disorder transition point at J 2  = J 1 /2. Nevertheless, when the J 3 and η values beyond the upper limits, it is a paramagnetic phase at J 2  = J 1 /2. For J 3  J 2  = J 1 /2. Therefore, for J 2  = J 1 /2, under such parameters, a first-order phase transition between the two states for these two cases below the critical temperatures may occur. When J 2  ≠ J 1 /2, the Néel and collinear states may also exist, while they have different critical temperatures. When J 2  > J 1 /2, a first-order phase transition between the two states may also occur. However, for J 2  J 1 /2, the Néel state is always more stable than the collinear state.

Fighting Nemo: Effect of 17α-ethinylestradiol (EE2) on aggressive behavior and social hierarchy of the false clown anemonefish Amphiprion ocellaris.

Science.gov (United States)

Chen, Te-Hao; Hsieh, Chun-Yu

2017-11-30

Aggressive behavior is crucial for maintaining social hierarchy in anemonefish. Endocrine disrupting chemicals such as EE2 may affect fish social hierarchy via disrupting their aggression. In this study, we aimed to characterize the effects of 17α-ethinylestradiol (EE2) on aggressive behavior and social hierarchy in the false clown anemonefish (Amphiprion ocellaris). In the laboratory experiment, juvenile anemonefish were randomly distributed to separated tanks to form small colonies of three individuals and were fed with EE2-dosed diet (100ng/g food) or a control diet for 90d. Through the experiment, each tank was videotaped and behavioral indicators of social status, including aggressive behavior, submissive response, and shelter utilization, were quantitatively analyzed from the videos. The EE2 exposure caused a higher frequency of intra-colonial aggressive interactions and a less stable social hierarchy. Our findings demonstrate the importance of examining the effects of endocrine disrupting chemicals on the social behavior of coral reef fish. Copyright © 2016 Elsevier Ltd. All rights reserved.

The ALICE experiment studied J/psi production in the mu+mu- and e+e- decay channels. Inclusive cross sections were measured at both forward and central rapidity down to zero transverse momentum. The results are compared with NRQCD calculations and, for the pp sample collected at sqrt(s)=2.76 TeV, are used as a reference for the determination of nuclear effects on J/psi production in Pb-Pb. At central rapidity, the fraction of J/psi coming from B-decays has been evaluated down to p_T=1.3 GeV/c. In addition, the J/psi yield has been found to linearly increase as a function of the charged hadron multiplicity produced in the collision. Finally, the first LHC results on J/psi polarization, an essential observable for the understanding of the production mechanisms and for theory comparisons, will be presented.

Full Text Available Se valora el uso de la plataforma virtual del recinto URACCAN-Nueva Guinea, en el área  de Ciencias Administrativas e Informática, implementada durante el II semestre del 2012. Se desarrolló bajo un enfoque cuantitativo empleando la encuesta como técnica de recolección de datos y entrevistas a fuentes específicas. La investigación da mayor relevancia a la plataforma virtual Moodle y sus características por ser el software educativo utilizado por el recinto universitario para desarrollar los procesos educativos en los entornos virtuales.Los resultados muestran el poco uso de la plataforma virtual, tanto de estudiantes y docentes, aunque la universidad ha realizado esfuerzo por capacitar a los docentes en metodologías a través de entornos virtuales; empero, el diseño de los cursos por algunos docentes no incentiva su uso: son pocos atractivos y no se aprovechan todas las opciones que la plataforma otorga para su uso eficiente. Los estudiantes y docentes ven con buenas expectativas y aprueban de manera complementaria la utilización de plataformas virtuales para el desarrollo de sus clases, ya que existen pocas condiciones en la universidad en cuanto al acceso y equipos para su implementación.SummaryThis study was carried out in order to evaluate the virtual platform use in URACCAN-Nueva Guinea campus, in the area of Administrative Sciences and Informatics, implemented during the second semester of the year 2012. It was developed with a quantitative approach using the survey as a technique for data collection and interviews with specific sources. The research gives major importance to the Moodle virtual platform and its characteristics, for being the educational software used by the campus to develop educational processes in virtual environments.The results show little use of the virtual platform, both by students and teachers, although the university has made efforts to train teachers in methodologies through virtual environments

Oral contraceptives may provide a reasonable delivery vehicle for folate supplementation before conception in women of childbearing potential. This study aimed to demonstrate that a fixed-dose combination of an oral contraceptive and levomefolate calcium leads to sustainable improvements in folate status compared with an oral contraceptive + folic acid. Methods: This was a double-blind, randomized, parallel-group study in which 172 healthy women aged 18–40 years received ethinylestradiol (EE-drospirenone-levomefolate calcium or EE-drospirenone + folic acid for 24 weeks (invasion phase, and EE-drospirenone for an additional 20 weeks (folate elimination phase. The main objective of the invasion phase was to examine the area under the folate concentration time-curve for plasma and red blood cell (RBC folate, while the main objective of the elimination phase was to determine the duration of time for which RBC folate concentration remained ≥ 906 nmol/L after cessation of EE-drospirenone-levomefolate calcium. Results: Mean concentration-time curves for plasma folate, RBC folate, and homocysteine were comparable between treatment groups during both study phases. During the invasion phase, plasma and RBC folate concentrations increased and approached steady-state after about 8 weeks (plasma or 24 weeks (RBC. After cessation of treatment with levomefolate calcium, folate concentrations decreased slowly. The median time to RBC folate concentrations falling below 906 nmol/L was 10 weeks (95% confidence interval 8–12 weeks after cessation

Highlights: •Studied impacts of ethynylestradiol (EE2) exposure on salmon pituitary transcriptome. •High-throughput sequencing, RNAseq, and pathway analysis were performed. •EE2 altered mRNAs for genes in circadian rhythm, GnRH, and TGFβ signaling pathways. •LH and FSH beta subunit mRNAs were most highly up- and down-regulated by EE2, respectively. •Estrogens may alter processes associated with reproductive timing in salmon. -- Abstract: Considerable research has been done on the effects of endocrine disrupting chemicals (EDCs) on reproduction and gene expression in the brain, liver and gonads of teleost fish, but information on impacts to the pituitary gland are still limited despite its central role in regulating reproduction. The aim of this study was to further our understanding of the potential effects of natural and synthetic estrogens on the brain–pituitary–gonad axis in fish by determining the effects of 17α-ethynylestradiol (EE2) on the pituitary transcriptome. We exposed sub-adult coho salmon (Oncorhynchus kisutch) to 0 or 12 ng EE2/L for up to 6 weeks and effects on the pituitary transcriptome of females were assessed using high-throughput Illumina{sup ®} sequencing, RNA-Seq and pathway analysis. After 1 or 6 weeks, 218 and 670 contiguous sequences (contigs) respectively, were differentially expressed in pituitaries of EE2-exposed fish relative to control. Two of the most highly up- and down-regulated contigs were luteinizing hormone β subunit (241-fold and 395-fold at 1 and 6 weeks, respectively) and follicle-stimulating hormone β subunit (−3.4-fold at 6 weeks). Additional contigs related to gonadotropin synthesis and release were differentially expressed in EE2-exposed fish relative to controls. These included contigs involved in gonadotropin releasing hormone (GNRH) and transforming growth factor-β signaling. There was an over-representation of significantly affected contigs in 33 and 18 canonical pathways at 1 and 6 weeks

The potential impact of endocrine disrupting chemicals (EDCs) in the aquatic environment has driven the development of screening assays to evaluate the estrogenic properties of chemicals and their effects on aquatic organisms such as fish. However, obtaining full concentration-response relationships in animal (in vivo) exposure studies are laborious, costly and unethical, hence a need for developing feasible alternative (non-animal) methods. Use of in vitro bioassays such as primary fish hepatocytes, which retain many of the native properties of the liver, has been proposed for in vitro screening of estrogen receptor (ER) agonists and antagonists. The aim of present study was to characterize the molecular mode of action (MoA) of the ER agonist 17α-ethinylestradiol (EE2) in primary rainbow trout (Oncorhynchus mykiss) hepatocytes. A custom designed salmonid 60,000-feature (60k) oligonucleotide microarray was used to characterize the potential MoAs after 48h exposure to EE2. The microarray analysis revealed several concentration-dependent gene expression alterations including classical estrogen sensitive biomarker gene expression (e.g. estrogen receptor α, vitellogenin, zona radiata). Gene Ontology (GO) analysis displayed transcriptional changes suggesting interference of cellular growth, fatty acid and lipid metabolism potentially mediated through the estrogen receptor (ER), which were proposed to be associated with modulation of genes involved in endocrine function and reproduction. Pathway analysis supported the identified GOs and revealed modulation of additional genes associated with apoptosis and cholesterol biosynthesis. Differentially expressed genes (DEGs) related to impaired lipid metabolism (e.g. peroxisome proliferator-activated receptor α and γ), growth (e.g. insulin growth factor protein 1), phase I and II biotransformation (e.g. cytochrome P450 1A, sulfotransferase, UDP-glucuronosyltransferase and glutathione S-transferase) provided additional

2016-01-01

The physics case for electron-positron beams at the Future Circular Collider (FCC-ee) is succinctly summarized. The FCC-ee core program involves $e^+e^-$ collisions at $\\sqrt{s}$ = 90, 160, 240, and 350 GeV with multi-ab$^{-1}$ integrated luminosities, yielding about 10$^{12}$ Z bosons, 10$^{8}$ W$^+$W$^-$ pairs, 10$^{6}$ Higgs bosons and 4$\\cdot$10$^{5}$ $t\\bar{t}$ pairs per year. The huge luminosities combined with $\\cal{100}$ keV knowledge of the c.m. energy will allow for Standard Model studies at unrivaled precision. Indirect constraints on new physics can thereby be placed up to scales $\\Lambda_{_{\\rm NP}} \\approx$ 7 and 100 TeV for particles coupling respectively to the Higgs and electroweak bosons.

The rotational spectrum of 2,6-dimethylcyclohexanone (DMCHO) was measured in the frequency region from 6 to 12 GHz. Among three possible conformational isomers, two conformers were identified where two methyl groups are aligned in the equatorial/equatorial (ee) and the equatorial/axial (ea) positions. Both b-type and c-type transitions for (e,e)-2,6-DMCHO, and a-type, b-type, and c-type transitions for (e,a)-2,6-DMCHO were assigned to determine the rotational constants and quartic centrifugal distortion constants based on the Watson-A reduction Hamiltonian: (ee) A = 2150.95789(48) MHz, B = 1578.76212(40) MHz, C = 990.19141(45) MHz, ΔJ = 0.086(11) kHz, ΔJK = -0.134(20) kHz, ΔK = 0.298(15) kHz, δJ = 23.4(24) Hz, and δK = 101.4(77) Hz; and (ea) A = 2082.62538(83) MHz, B = 1566.59564(59) MHz, C = 1113.90153(75) MHz, ΔJ = 0.066(23) kHz. In addition, dipole moment components of the two isomers were determined by Stark effect measurements: (ee) μb = 2.6673(12) D, μc = 1.0379(11) D, μtotal = 2.8621(12) D; and (ea) μa = 1.385(253) D, μb = 2.358(104) D, μc = 1.172(21) D, μtotal = 2.975(144) D. Ab initio calculations for all three isomers were compared with each other and with experimental results.

Full Text Available The main goal of the study is to introduce the Czech version of Emotional Empathy Scale (EES-R and its psychometric characteristics. The scale, developed from the Emotional Empathy Scale (EES by Caruso and Mayer (1998, is devoted to self-report assessment in the frame of multidimensional emotional empathy construct. Partial objectives of this study focus on the factor structure, reliability and validity of the scale with regard to verification of application possibilities. One of the objectives is aimed at a description of the subscales of EES-R, especially for the research use. The data were obtained on the sample of 317 respondents aged from 19 to 62 years, namely 44.2 % men and 55.8 % women. Besides the Czech translation of EES and the Czech version of the scale (EES-R, 3 subscales from the Business-focused Inventory of Personality (BIP were used for the verification of the parallel validity. The exploratory factor analysis led to the three-factor solution. Three resulted subscales of the scale, labelled as Compassion – solidarity, Emotional feeling and Positive sharing, represented individual factors and showed an adequate prop in both data and theory. The confirmatory factor analysis conducted with EES-R confirmed a corresponding match between the model and data. The internal consistency of subscales items showed a reliability ranging from 0.72 to 0.87, with the value of 0.89 for the whole scale. Satisfactory values of test-retest reliability were obtained for the subscales (0.69 to 0.83 and the whole scale (.79 after three months. Results of the parallel validity for the emotional empathy construct measured by EES-R correspond with previous research findings. In case of growing emotional empathy also sensitivity and sociability were slightly growing. On the contrary, the emotional stability was slightly decreasing. The characteristics of EES-R were described on our sample with respect to gender and age. This method demonstrated good

A Study of J/psi Production at the LEP $e^{+} e{-}$ Collider; and the Implementation of the DELPHI Slow Controls System

CERN Document Server

Adye, T J

1998-01-01

This thesis describes two separate areas of work conducted for the DELPHI detector at LEP. The first concerns the Slow Controls of the DELPHI detector, which enable a single operator to oversee the proper functioning of the apparatus and to diagnose faults as they occur. The hardware and software of this system, as well as their interface to the experiment and the operator, are described. Some conclusions are drawn from seven years' design work and the initial six years' operation of DELPHI. Secondly, a study is made of the production, at e+e- collision centre of mass energies close to the Z0 resonance, of J/psi mesons, decaying to mu+ mu-. J/psi mesons produced via a B-hadron are used to measure the mean B lifetime, tau_B = (1.53 +- 0.11 (stat.) +- 0.06 (syst.)) ps A measurement is also made of the fraction of J/psis produced promptly at the e+e- collision point, N(Z0 -> prompt J/psi X) / N(Z0 -> J/psi X) = (9.6 +- 3.2 (stat.) +- 1.2 (syst.))%. This method is largely model-independent.

Full Text Available Resumen: En este trabajo se propone el uso de plataformas para el desarrollo de aplicaciones virtuales como herramientas para el modelado de robots manipuladores. La propuesta se basa en aprovechar el gran potencial que actualmente tienen estas plataformas para solucionar la dinámica de cuerpos rígidos, lo que permite modelar de forma sencilla los aspectos mecánicos del manipulador. Por otro lado, la posibilidad ofrecida por estas plataformas de incorporar código de programación en lenguajes convencionales, permite modelar el comportamiento dinámico de sistemas físicos reales, tales como sensores y actuadores, lo que hace posible la implementación de una etapa virtual de instrumentación y control tal y como se realiza en un robot real. El uso de estas plataformas permite modelar desde cero cualquier robot manipulador. El modelado de un robot paralelo reconfigurable es presentado como caso de estudio. Abstract: This paper describes the use of platforms for the development of virtual applications as tools for modeling of robot manipulators. The proposal is based on take advantage of the potential that these platforms currently have for solving the rigid body dynamics, which easily allows modeling the mechanical aspects of the manipulator. On the other hand, the possibility offered by these platforms of incorporate programming code in conventional languages allows to modeling the dynamic behavior of real physical systems, such as sensors and actuators, which allows implementing the development of the instrumentation and control stage of an industrial robot in the same way as a real one. Using these platforms allows the modeling from the bases of any manipulator robot. The modeling of a reconfigurable parallel robot is presented as a case study.

The FCC-ee aims to improve on electroweak precision measurements, with goals of 100 ke V on the Z mass and width, and a fraction of MeV on the W mass. Compared to LEP, this implies a much improved knowledge of the center-of-mass energy when operating at the Z peak and WW threshold. This can be achieved by making systematic use of resonant depolarization. A number of issues have been identified, due in particular to the long polarization times. However the smaller emittance and energy spread of FCC-ee with respect to LEP should help achieve a much improved performance.

This document provides input from the CLIC e+e- linear collider studies to the update process of the European Strategy for Particle Physics. It is submitted on behalf of the CLIC/CTF3 collaboration and the CLIC physics and detector study. It describes the exploration of fundamental questions in particle physics at the energy frontier with a future TeV-scale e+e- linear collider based on the Compact Linear Collider (CLIC) two-beam acceleration technique. A high-luminosity high-energy e+e- collider allows for the exploration of Standard Model physics, such as precise measurements of the Higgs, top and gauge sectors, as well as for a multitude of searches for New Physics, either through direct discovery or indirectly, via high-precision observables. Given the current state of knowledge, following the observation of a \\sim125 GeV Higgs-like particle at the LHC, and pending further LHC results at 8 TeV and 14 TeV, a linear e+e- collider built and operated in centre-of-mass energy stages from a few-hundred GeV up t...

Sensitivities of Prospective Future e+e- Colliders to Decoupled New Physics

CERN Document Server

Ellis, John

2016-01-01

We explore the indirect sensitivities to decoupled new physics of prospective precision electroweak measurements, triple-gauge-coupling measurements and Higgs physics at future $e^+e^-$ colliders, with emphasis on the ILC250 and FCC-ee. The Standard Model effective field theory (SM EFT) is adopted as a model-independent approach for relating experimental precision projections to the scale of new physics, and we present prospective constraints on the Wilson coefficients of dimension-6 operators. We find that in a marginalised fit ILC250 EWPT measurements may be sensitive to new physics scales $\\Lambda = \\mathcal{O}(10)$~TeV, and FCC-ee EWPT measurements may be sensitive to $\\Lambda = \\mathcal{O}(30)$~TeV. The prospective sensitivities of Higgs and TGC measurements at the ILC250 (FCC-ee) are to $\\Lambda = \\mathcal{O}(1)$~TeV ($\\Lambda = \\mathcal{O}(2)$~TeV).

En cada una de las tres opciones existen aspectos a considerar, aunque posiblemente actualmente muchas docentes se inclinan por el uso de plataformas de "software libre".

Pero uno de los mayores valores añadidos que hay que tener en cuenta para el éxito de un proyecto docente basado en las TIC, es la capacidad de dinamización del mismo y la creación de un ambiente colaborativo por parte del profesor/tutor. Estos tres elementos que podemos tildar de "actores" en el proceso de aprendizaje con el uso de las TIC, serán fundamentales en el momento en que la sociedad decida realizar un cambio revolucionario en la educación, si consigue a través de proyectos mundiales como "Laptop for children" socializar el acceso a la información y al conocimiento.

LHCb experiment has been designed in order to do precise measurements of CP violation and rare decays with B mesons. In 2000, the collaboration decided to modify the spectrometer in order to minimize the amount of matter seen by particles and to optimize the trigger. This thesis was done in this context and is divided into 3 parts. The first part is relative to the electron identification and to the recovery of Bremsstrahlung photons emitted by electrons when they pass through matter. Electron identification is mainly based on information provided by calorimeter system but also uses RICH and muon system. A method based on reference histograms had been developed which combine information provided by these detectors. Electron identification efficiency, for electrons in ECAL acceptance is 95% and the pion mis-identification rates 0.8% with a 65% purity of electron sample. Bremsstrahlung recovery allows the selection of J/{phi} decaying in e{sup +}e{sup -} pair and of B{sub d}{sup 0} {yields} J/{phi}(ee)K{sub S}{sup 0} channel which are described in the second part. The selection of this channel was developed in order to get an acceptable selection efficiency with a good rejection of background. A set of kinematic and topological cuts were designed and total selection efficiency is 0.176%, corresponding to 28000 untagged events reconstructed by year, with a ratio B/S belonging to [0.017;0.069] (at 90% of confidence level) for inclusive bb-bar background. In the third part, B meson flavour tagging is presented. The addition of information provided by the vertex locator allows to reject electron coming from conversion and to improve slightly the performances. The LHCb sensibility to sin(2{beta}) from B{sup 0} {yields} J/{psi}K{sub S}{sup 0} decay is also determined. The statistical error, expected after one year of data collecting, corresponding to an integrated luminosity of 2 fb{sup -1} and bb-bar pair cross section of 0.5 mb, varies from 0.015 to 0.020 according to

The inclusive J/$\\psi$ nuclear modification factor ($R_{AA}$) in Pb-Pb collisions at $\\sqrt{s_{NN}}$=2.76TeV has been measured by ALICE as a function of centrality in the $e^+e^-$ decay channel at mid-rapidity |y| < 0.8 and as a function of centrality, transverse momentum and rapidity in the $\\mu^+\\mu^-$ decay channel at forward-rapidity 2.5 < y < 4.The J/$\\psi$ yields measured in Pb-Pb are suppressed compared to those in pp collisions scaled by the number of binary collisions.The $R_{AA}$ integrated over a centrality range corresponding to 90% of the inelastic Pb-Pb cross section is 0.72 +- 0.06 (stat.) +- 0.10 (syst.) at mid-rapidity and 0.57 +- 0.01 (stat.) +- 0.09 (syst.) at forward-rapidity. At low transverse momentum, significantly larger values of $R_{AA}$ are measured at forward-rapidity compared to measurements at lower energy.These features suggest that a contribution to the J/$\\psi$ yield originates from charm quarks (re)combination in the deconfined partonic medium.

HOM power in FCC-ee cavities

CERN Document Server

Karpov, Ivan; Chapochnikova, Elena

2018-01-01

This Note summarizes the results of the power loss calculations for FCC-ee machines with 400.79 MHz cavity options. The requirements for the single-cell cavity design and for the operation with beam are obtained from the results for the high-current FCC-ee machine (Z). For other machines the power loss is sufficiently low and can be absorbed and extracted by foreseen HOM couplers.

The FCC (Future Circular Collider) study represents a vision for the next large project in high energy physics, comprising an 80-100 km tunnel that can house a future 100 TeV hadron collider. The study also includes a high luminosity e+e- collider operating in the centre-of-mass energy range of 90-350 GeV as a possible intermediate step, the FCC-ee. The FCC-ee aims at definitive electro-weak precision measurements of the Z, W, H and top particles, and search for rare phenomena. Although FCC-ee is based on known technology, the goal performance in luminosity and energy calibration make it quite challenging. During 2014 the study went through an exploration phase. The study has now entered its second year and the aim is to produce a conceptual design report during the next three to four years. We here report on progress since the last IPAC conference.

Search for Resonant s-channel Higgs Production at a future high-luminosity e+e- collider (FCC-ee)

CERN Document Server

Wojcik, George

2014-01-01

In this project, the plausibility of measuring direct resonant s-channel Higgs production at a future high-luminosity e+e- collider machine (of the FCC-ee type) is examined. Using PYTHIA8 to generate expected samples for signal (e+e--->H-->WW*,ZZ*,bbar,gluon-gluon) and backgrounds (e+e- -->Z*,gamma*-->qqbar,tautau,WW,ZZ) in seven possible Higgs decay channels (combining isolated leptons, neutrinos and heavy-quark, light-quark and gluon jets), a total combined statistical significance of 3.6 sigma per experiment is obtained at an integrated luminosity of 10 $ab^{-1}$. This preliminary result, not accounting yet for signal loss from ISR and beam energy spreading, seems to confirm the possibility to access (or at least put strong constraints) on the fundamental Yukawa coupling of the Higgs boson to electrons.

17α-Ethinylestradiol (EE2) treatment of wild roach (Rutilus rutilus) during early life development disrupts expression of genes directly involved in the feedback cycle of estrogen.

Fish are more sensitive to introduced disturbances from synthetic endocrine disrupting compounds during early life phases compared with mature stages. 17α-Ethinylestradiol (EE2), which is the active compound in human oral contraceptives and hormone replacement therapies, is today ever present in the effluents from sewage treatment plants. EE2 targets and interacts with the endogenous biological systems of exposed vertebrates resulting in to large extents unknown short- and long-term effects. We investigated how EE2 exposure affects expression profiles of a large number of target genes during early life of roach (Rutilus rutilus). We exposed fertilized roach eggs collected from a lake in Southern Sweden to EE2 for 12weeks together with 1+-year-old roach in aquaria. We measured the gene expression of the estrogen receptor (esr)1/2a/2b, androgen receptor (ar), vitellogenin, cytochrome P450 (cyp)19a1a/1b in fertilized eggs; newly hatched larvae; 12-week-old fry; and juvenile wild roach (1+-year-old). Results shows that an EE2 concentration as low as 0.5ng/L significantly affects gene expression during early development. Gene expression responses vary both among life stages and molecular receptors. We also show that the gene profile of the estrogen feedback cycle to a large extent depends on the relationship between the three esr genes and the two cyp19a1 genes, which are all up-regulated with age. Results indicate that a disruption of the natural activity of the dominant esr gene could lead to detrimental biological effects if EE2 exposure occurs during development, even if this exposure occurred for only a short period.

The construction is entirely wooden and is lifted above the ground by 9 exposed piles to which are bolted the beams that support the exposed ceiling Joists. For these elements laminated yellow pine wood has been used as well as for the floorings, roofs and deckings. The walls are of panelled cedar plywood whereas the material of the interior doors and cabinetry is mahogany.Esta vivienda se diseñó como una secuencia de plataformas que ascienden, en espiral continua, alrededor de una escalera interior, en las cuales se dispusieron: el cuarto de estar, los dormitorios de padres y de niños, un estudio, el comedor y la cocina, una habitación para los invitados y, debajo del edificio, una plaza de aparcamiento. La construcción, realizada con madera en su totalidad, se levanta del suelo mediante nueve pilares vistos, a los que se atornillan las jácenas que soportan las viguetas, también vistas, de los forjados. Para estos elementos constructivos se empleó madera laminada de pino amarillo, al igual que para los suelos, techos y cubiertas. Los muros laterales se hicieron con un entablado de madera contrachapada de cedro, mientras que para el artesonado, las puertas interiores y las estanterías, se utilizó la madera de caoba.

The transverse momentum ($p_{\\rm T}$) dependence of the nuclear modification factor $R_{\\rm AA}$ and the centrality dependence of the average transverse momentum $\\langle p_{\\rm T}\\rangle$ for inclusive J/$\\psi$ have been measured with ALICE for Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}$ = 2.76 TeV in the e$^+$e$^-$ decay channel at mid-rapidity ($|y|<0.8$). The $\\langle p_{\\rm T}\\rangle$ is significantly smaller than the one observed for pp collisions at the same centre-of-mass energy. Consistently, an increase of $R_{\\rm AA}$ is observed towards low $p_{\\rm T}$. These observations might be indicative of a sizable contribution of charm quark coalescence to the J/$\\psi$ production. Additionally, the fraction of non-prompt J/$\\psi$ from beauty hadron decays, $f_{\\rm B}$, has been determined in the region $1.5 < p_{\\rm T} < 10$ GeV/c in three centrality intervals. No significant centrality dependence of $f_{\\rm B}$ is observed. Finally, the $R_{\\rm AA}$ of non-prompt J/$\\psi$ is discussed and compared wit...

Evidence for short range corelations from high Q2 (e,e') reactions

International Nuclear Information System (INIS)

Strikman, M.I.; Frankfurt, L.L.; Sargayan, M.M.

1994-01-01

For many years now short-range correlations (SRC) in nuclei have been considered as an essential feature of the nuclear wave function. At high energy (e,e') reactions, where Q 2 > 1 (GeV/c) 2 , x = Q 2 /2mq o > 1 and 1 GeV > q o > 300 ∼ 400 MeV the scattering from low momentum nucleons is kinematically suppressed and there the evidence of SRC expected to be more prominent. These reactions have been intensively investigated during the last decade or so at SLAC on both light and heavy nuclei. The above kinematics allows one to compute the cross section through the processes local in space. To explain this the authors analyse the representation of the cross section as a Fourier transform of the commutator of electromagnetic currents and see that the major contribution in the cross section is given by the region of integration

QCD and $\\gamma\\,\\gamma$ studies at FCC-ee

CERN Document Server

Skands, Peter

2016-10-20

The Future Circular Collider (FCC) is a post-LHC project aiming at searches for physics beyond the SM in a new 80--100~km tunnel at CERN. Running in its first phase as a very-high-luminosity electron-positron collider (FCC-ee), it will provide unique possibilities for indirect searches of new phenomena through high-precision tests of the SM. In addition, by collecting tens of ab$^{-1}$ integrated luminosity in the range of center-of-mass energies $\\sqrt{s}$~=90--350~GeV, the FCC-ee also offers unique physics opportunities for precise measurements of QCD phenomena and of photon-photon collisions through, literally, billions of hadronic final states as well as unprecedented large fluxes of quasireal $\\gamma$'s radiated from the $\\rm e^+e^-$ beams. We succinctly summarize the FCC-ee perspectives for high-precision extractions of the QCD coupling, for detailed analyses of parton radiation and fragmentation, and for SM and BSM studies through $\\gamma\\gamma$ collisions.

Precision Electroweak measurements at the FCC-ee

CERN Document Server

Dam, Mogens

2016-01-01

Because of a luminosity of up to five orders of magnitude larger than at LEP, electroweak precision measurements at the FCC-ee -- the Future Circular Collider with electron-positron beams -- would provide improvements by orders of magnitude over the present status and constitute a broad search for the existence of new, weakly interacting particles up to very high energy scales. The FCC-ee will address centre-of-mass energies ranging from below the Z pole to the $\\mathrm{t\\bar{t}}$ threshold and above. At energies around the Z pole, the Z-boson mass and width can be measured to better than 100 keV each.

The predictive role of E/e' on ischemic stroke (IS) and atrial fibrillation (AF) in Japanese patients without AF are unclear. Shinken database includes all the new patients visiting the Cardiovascular Institute Hospital in Tokyo, Japan. E/e' has been routinely measured since 2007. Patients without AF for whom E/e' was measured at the initial visit between 2007 and 2014 (n=11 477, mean age 57.2 years old, men 59.5%) were divided into E/e' tertiles (11.00). During the mean follow-up period of 1.8 years, 58 IS and 140 new appearances of AF were observed. High E/e' tertile was associated with more prevalence of atherothrombotic risks. The cumulative incidence of IS events and new appearance of AF at 6 years in low, middle, and high E/e' tertiles were 0.5%, 1.4%, and 3.0%/year (log-rank test, pE/e' tertile was independently associated with IS (HR, 2.857, 95%CI 1.257-6.495, p=0.012). Although high E/e' tertile was independently associated with new appearance of AF when adjusted for coexistence of atherothrombotic risk factors (HR, 1.694, 95%CI, 1.097-2.616, p=0.017), the association was attenuated after adjustment for left atrial dimension. E/e' was significantly associated with incidence of IS and new appearance of AF in non-AF patients. Copyright © 2018 Japanese College of Cardiology. Published by Elsevier Ltd. All rights reserved.

Purpose: The purpose of this work is to present a platform for designing and executing studies that compare pathologists interpreting histopathology of whole slide images (WSI) on a computer display to pathologists interpreting glass slides on an optical microscope. Methods: Here we present eeDAP, an evaluation environment for digital and analog pathology. The key element in eeDAP is the registration of theWSI to the glass slide. Registration is accomplished through computer control of the microscope stage and a camera mounted on the microscope that acquires images of the real time microscope view. Registration allows for the evaluation of the same regions of interest (ROIs) in both domains. This can reduce or eliminate disagreements that arise from pathologists interpreting different areas and focuses the comparison on image quality. Results: We reduced the pathologist interpretation area from an entire glass slide (≈10-30 mm)2 to small ROIs google.com (project: eeDAP) as Matlab source or as a precompiled stand-alone license-free application.

2013-10-01

Full Text Available INTRODUÇÃO: Nos últimos anos muitos estudos foram feitos com o objetivo de avaliar a utilização da vibração mecânica como parte de treinamento para melhora do condicionamento físico. Entretanto, a maioria avaliou os efeitos dos exercícios em conjunto com o treinamento vibratório para determinar se havia melhora após o treinamento, sem avaliar os efeitos dos exercícios realizados na plataforma com e sem vibração. OBJETIVO: Avaliar o efeito agudo do exercício nos extensores do joelho, com e sem o estímulo da plataforma vibratória. MÉTODOS: Trinta indivíduos ativos, do sexo masculino, com idades entre 18 e 45 anos, realizaram, de forma randomizada, três protocolos: grupo plataforma ligada (GPL, grupo plataforma desligada (GPD e grupo controle (GC. Cada protocolo começava com aquecimento de cinco minutos em bicicleta ergométrica, com carga entre 75 e 100 watts e 70 rotações por minuto, seguido por seis séries de 10 movimentos de agachamento unilateral com intervalo de um minuto entre elas, com ou sem vibração mecânica, e terminava com o Work Test, realizado apenas no membro inferior dominante para determinação das valências físicas: trabalho, força, potência e velocidade. O grupo controle realizou apenas o Work Test após o aquecimento. RESULTADOS: Apenas a variável velocidade apresentou diferença estatisticamente significante (p < 0,05 quando comparado o GPL ao GC. CONCLUSÃO: O estímulo na plataforma vibratória não exerceu influência nas variáveis trabalho e potência dos extensores do joelho unilateral, mas, na velocidade do movimento, exerceu influência negativa causando fadiga.

The "CERN-BINP workshop for young scientists in e+e- colliders" is organised in the framework of the EU-funded CREMLIN project. The CREMLIN project aims at strengthening science cooperation between six Russian megascience facilities and related research infrastructure counterparts in Europe. BINP and CERN coordinate a dedicated CREMLIN work package focusing on a future super-charm-tau factory (SCT) at BINP. SCT aims at producing e+e- collisions with up to 5 GeV centre-of-mass energy and at very high luminosity. In parallel CERN is hosting design studies for two possible high-energy e+e- colliders: FCC-ee and CLIC. In matters of physics, design and technologies the BINP and CERN studies address technological and scientific questions of common interest. Similar issues are dealt with in the framework of other flavour factories and energy frontier e+e- colliders worldwide.

submitter Prospects of Sterile Neutrino Search with the FCC-ee

CERN Document Server

Bay Nielsen, Sissel

A proposed future circular e + e − collider, the FCC-ee, is suggested to search for sterile neutrinos. The Neutrino Minimal Standard Model, νMSM, is a model of sterile neutrinos, that accommodates explanations for several phenomena of physics beyond the Standard Model. This thesis presents an overview of the theoretical motivation for νMSM, an outline of the experimental conditions at the FCC-ee, and a review of previous accelerator bounds for sterile neutrinos. Two studies of sterile neutrinos with masses at the electroweak scale are introduced, an analysis of long lived sterile neutrinos, and an analysis of short lived sterile neutrinos. Both analyses include background studies and sensitivity estimates for the FCC-ee detector. The study of long lived sterile neutrinos is based on a search for detectable displaced vertices with 1012 Z decays, obtaining a search reach on the mixing angle |θ| 2 as small as 10−11. The study of short lived sterile neutrinos is a Monte Carlo study with a cut-based analysi...

2014-05-01

Recent evidence indicates that genetic hypertension in BPH/2J mice is sympathetically mediated, but these mice also have lower body weight (BW) and elevated locomotor activity compared with BPN/3J normotensive mice, suggestive of metabolic abnormalities. The aim of the present study was to determine whether hypertension in BPH/2J mice is associated with metabolic differences. Whole-body metabolic and cardiovascular parameters were measured over 24 h by indirect calorimetry and radiotelemetry respectively, in conscious young (10-13 weeks) and older (22-23 weeks) BPH/2J, normotensive BPN/3J and C57Bl6 mice. Blood pressure (BP) was greater in BPH/2J compared with both normotensive strains at both ages (PBPH/2J compared with BPN/3J mice (PBPH/2J and normotensive mice when adjusted for activity (P>0.1) suggesting differences in this relationship are not responsible for hypertension. EchoMRI revealed that percentage body composition was comparable in BPN/3J and BPH/2J mice (P>0.1) and both strains gained weight similarly with age (P=0.3). Taken together, the present findings indicate that hypertension in BPH/2J mice does not appear to be related to altered energy metabolism.

Our research team proposed to test the toxic effect caused by ethinylestradiol on embryo development in common carp (Cyprinus carpio. Common carp embryos were purchased from the fish farm S.C. Acva Prod S.R.L. Cefa, Bihor County these were obtained by artificial reproduction. After taking and selection, the fecundated spawns were introduced in 10 Nunk culture plates of 45 ml, where we introduced 40 ml water, too. We created 3 batches, with two replications, namely: batch 1 – control, batch 2 – in water, we added ethinylestradiol (EE2 in concentration of 1.5 ng L-1 and batch 3 – we added in water a concentration of 7 ng L-1 EE2. During the incubation, the Nunk plates were kept in breeding aquariums, at a temperature of 24°C. Successive to the supervision of embryos in batch 3, 48 hours post-fecundation, we could observe evolution stagnations, 70% of them being in the stage of 40 somites of the segmentation period. At the same age, 100% of the control batch- embryos entered the stage of advanced faringula, and in batch 2 all embryos were in the stage of incipient faringula. 60-72 hours post-fecundation, all embryos in the batch 3 died, 90% in the 40 somite stage of the segmentation period and 10% in the stage of incipient faringula. 85 hours post-fecundation, all embryos belonging to the control batch were in the larva stage, while in batch 2, 90% were in the larva stage and 10% died in the stage of advanced faringula.

The impact of tissue Doppler index E/e' ratio on instantaneous wave-free ratio.

The instantaneous wave-free ratio (iFR) is a vasodilator-free, invasive pressure wire index of the functional severity of coronary stenosis and is calculated under resting conditions. In a recent study, iFR was found to be more closely linked to coronary flow reserve (CFR) than fractional flow reserve (FFR). E/e' is a surrogate marker of left ventricular (LV) filling pressure and LV diastolic dysfunction. Coronary resting flow was found to be increased in patients with elevated E/e', and higher coronary resting flow was associated with lower CFR. Higher baseline coronary flow induces a greater loss of translesional pressure and may affect iFR. However, no reports have examined the impact of E/e' on iFR. The purpose of this study was to assess the relationship between iFR and E/e' compared with FFR. We retrospectively examined 103 consecutive patients (142 with stenosis) whose iFR, FFR, and E/e' were measured simultaneously. The mean age, LV mass index, and systolic blood pressure of patients with elevated E/e' were higher than those of patients with normal E/e'. Although no significant differences were observed in mean FFR values and % diameter stenosis, the mean iFR value in patients with elevated E/e' was significantly lower than that in patients with normal E/e'. The iFR was negatively correlated with E/e', while there was no correlation between FFR and E/e'. Multivariate analysis showed that E/e' and % diameter stenosis were independent determinants of iFR. E/e' ratio affects iFR values. Our results suggest that FFR mainly reflects the functional severity of the epicardial stenosis whereas iFR could potentially be influenced by not only epicardial stenosis but also other factors related to LV filling pressure or LV diastolic dysfunction. Further research is needed to understand the underlying mechanisms that influence the evaluation of iFR in patients with elevated E/e'. Copyright © 2017 Japanese College of Cardiology.

U (1 ) -symmetric infinite projected entangled-pair states study of the spin-1/2 square J1-J2 Heisenberg model

Haghshenas, R.; Sheng, D. N.

2018-05-01

We develop an improved variant of U (1 ) -symmetric infinite projected entangled-pair states (iPEPS) ansatz to investigate the ground-state phase diagram of the spin-1 /2 square J1-J2 Heisenberg model. In order to improve the accuracy of the ansatz, we discuss a simple strategy to select automatically relevant symmetric sectors and also introduce an optimization method to treat second-neighbor interactions more efficiently. We show that variational ground-state energies of the model obtained by the U (1 ) -symmetric iPEPS ansatz (for a fixed bond dimension D ) set a better upper bound, improving previous tensor-network-based results. By studying the finite-D scaling of the magnetically order parameter, we find a Néel phase for J2/J1place at J2c2/J1=0.610 (2 ) to the conventional Stripe phase. We compare our results with earlier DMRG and PEPS studies and suggest future directions for resolving remaining issues.

A search is performed for the production of the ψ(2S) in e + e - annihilation at a center-of-mass energy of 4.03 GeV using the BES detector operated at the Beijing Electron Positron Collider (BEPC). The kinematic features of the reconstructed ψ(2S) signal are consistent with its being produced only in association with an energetic photon resulting from initial state radiation (ISR). Limits are placed on ψ(2S) production from the decay of unknown charmonia or metastable hybrids that might be produced in e + e - annihilations at 4.03GeV. Under the assumption that the observed cross section for ψ(2S) production is due entirely to ISR, the partial width Γ ee of the ψ(2S) is measured to be 2.07±0.32keV. copyright 1998 The American Physical Society

FCC-ee accelerator parameters, performance and limitations

CERN has recently launched the Future Circular Collider (FCC) study to deal with all aspects of an ambitious post-LHC possible programme. The emphasis of the study is on a 100 TeV proton collider to be housed in a 80-100 km new ring in the Geneva region. An electron machine will also be considered as a possible intermediate first step (FCC-ee). The study benefits from earlier work done in the context of TLEP and has already published a parameter table, to serve as the basis for the work to be done. The study aims to publish a conceptual design report at around 2018. The recent discovery of a light Higgs boson has opened up considerable interest in circular e+e- Higgs factories around the world. FCC-ee is capable of very high luminosities in a wide centre-of-mass (ECM) spectrum from 90 to 350 GeV. This allows the very precise study of the Z, W and H bosons as well as the top quark, allowing for meaningful precision tests of the closure of the Standard Model.

Vascular endothelial overexpression of human CYP2J2 (Tie2-CYP2J2 Tr) modulates cardiac oxylipin profiles and enhances coronary reactive hyperemia in mice

Arachidonic acid is metabolized to epoxyeicosatrienoic acids (EETs) by cytochrome (CYP) P450 epoxygenases, and to ω-terminal hydroxyeicosatetraenoic acids (HETEs) by ω-hydroxylases. EETs and HETEs often have opposite biologic effects; EETs are vasodilatory and protect against ischemia/reperfusion injury, while ω-terminal HETEs are vasoconstrictive and cause vascular dysfunction. Other oxylipins, such as epoxyoctadecaenoic acids (EpOMEs), hydroxyoctadecadienoic acids (HODEs), and prostanoids also have varied vascular effects. Post-ischemic vasodilation in the heart, known as coronary reactive hyperemia (CRH), protects against potential damage to the heart muscle caused by ischemia. The relationship among CRH response to ischemia, in mice with altered levels of CYP2J epoxygenases has not yet been investigated. Therefore, we evaluated the effect of endothelial overexpression of the human cytochrome P450 epoxygenase CYP2J2 in mice (Tie2-CYP2J2 Tr) on oxylipin profiles and CRH. Additionally, we evaluated the effect of pharmacologic inhibition of CYP-epoxygenases and inhibition of ω-hydroxylases on CRH. We hypothesized that CRH would be enhanced in isolated mouse hearts with vascular endothelial overexpression of human CYP2J2 through modulation of oxylipin profiles. Similarly, we expected that inhibition of CYP-epoxygenases would reduce CRH, whereas inhibition of ω-hydroxylases would enhance CRH. Compared to WT mice, Tie2-CYP2J2 Tr mice had enhanced CRH, including repayment volume, repayment duration, and repayment/debt ratio (P iso-PGF2α (P < 0.05). Inhibition of CYP epoxygenases with MS-PPOH attenuated CRH (P < 0.05). Ischemia caused a decrease in mid-chain HETEs (5-, 11-, 12-, 15-HETEs P < 0.05) and HODEs (P < 0.05). These data demonstrate that vascular endothelial overexpression of CYP2J2, through changing the oxylipin profiles, enhances CRH. Inhibition of CYP epoxygenases decreases CRH, whereas inhibition of ω-hydroxylases enhances CRH. PMID:28328948

Simulación de Plataformas Robóticas de Movimiento para Aplicaciones de Realidad Virtual Mediante Filtros Digitales

Directory of Open Access Journals (Sweden)

Sergio Casas

2017-10-01

Full Text Available Resumen: El uso de plataformas robóticas de movimiento en simuladores de vehículos y aplicaciones de Realidad Virtual es relativamente habitual. Sin embargo, el ajuste de los algoritmos que controlan su funcionamiento, denominados algoritmos de washout, no es sencillo y requiere de numerosas pruebas hasta obtener una apropiada fidelidad de movimiento. Disponer de herramientas que permitan simular plataformas de movimiento puede permitir simplificar esta tarea. Es por ello que este trabajo presenta un método para la caracterización y simulación de manipuladores robóticos mediante filtros digitales de segundo orden, sencillo de implementar y ajustar a partir de una caracterización previa. El simulador se construye con el objetivo de permitir la simulación rápida de manipuladores robóticos y se ejemplifica con una plataforma de dos grados de libertad, aunque el método propuesto podría emplearse en otros dispositivos. En las pruebas realizadas se valida la precisión y velocidad de la simulación, concluyéndose que se obtiene una fidelidad satisfactoria y una velocidad de simulación elevada que permite emplear el simulador como sustituto del hardware real con algoritmos de washout. Abstract: Robotic motion platforms are used in many vehicle simulators and Virtual Reality applications. However, the set-up of the so-called washout algorithms that control the generation of self-motion is a hard process, since a great deal of tests need to be performed before reaching a proper motion fidelity. The availability of simulation tools eases this tuning task. Therefore, a motion platform characterization and simulation method is proposed in this paper. The method relies on second order digital filters and provides a reliable, yet very fast simulation system, which is assessed by means of a two degree-of-freedom motion platform, although the method might be applied to simulate other motion mechanisms.

Experiments on multiparton final states in e+e- annihilation at √s=30 GeV (MARK-J/PETRA)

International Nuclear Information System (INIS)

Hariri, S.

1982-03-01

This work is devoted to an experimental study of the quantum chromodynamics (Q.C.D.) matrix element. The first chapter consists of a general introduction, theoretical and phenomenological. In the second chapter, we give an elementary description of the detector. In addition to the topological methods given there, the third chapter contains a presentation of the MULTIJET analysis especially designed to study Q.C.D. matrix element. The fourth chapter begins with an application to MARK J data of the topological analysis described in the third chapter. Since the detector is a calorimeter, the transformation of particles into pseudo-particles introduces an additional effect which adds to hadronization effects. The BantiB model is a restriction of the quark model to the production of b quarks. The comparison of this model to the data shows that such a purely hadronic model is able to reproduce the experimentally observed rate of events called three jets. Nevertheless, the matrix element, corresponding to the BantiB model three jet events, is completely excluded by the data. The same statement applies to the quark model with wide hadronization. The fact that the data favours clearly Q.C.D. predictions is shown for differents values of (epsilon, delta) and for different variables (Nsub(J), Tsub(J), σsub(3J)). In the fifth chapter our Q.C.D. model with 2 and 3 jets is precisely defined. The systematical errors, experimental and theoretical are given in this chapter. Since the number of active flavours can affect our results, the exclusions of an open production of a sixth flavour with +-2/3 or +-1/3 is given there and an upper limit on the possible rate of 4 jet events is defined. The obtained results being in full agreement with our (2 and 3)-jet Q.C.D. model, the rapid convergence of the perturbative series at √s=30 GeV is confirmed once more [fr

We report the first observational search for tau neutrinos (ν τ ) from gamma-ray bursts (GRBs) using one of the Ashra light collectors. The Earth-skimming ν τ technique of imaging Cherenkov τ showers was applied as a detection method. We set stringent upper limits on the ν τ fluence in PeV-EeV region for 3780 s (between 2.83 and 1.78 hr before) and another 3780 s (between 21.2 and 22.2 hr after) surrounding GRB081203A triggered by the Swift satellite. This first search for PeV-EeV ν τ complements other experiments in energy range and methodology, and suggests the prologue of 'multi-particle astronomy' with a precise determination of time and location.

Highlights: • Agonistic and antagonistic activity of CMA and CPA were assessed in vitro. • CMA and CPA showed different interaction with human and fish receptors. • No progestogenic but antiandrogenic and antiglucocorticoid activity occurred in fish. • CMA and CPA showed transcriptional changes in zebrafish embryos. • Binary mixtures of the progestins with EE2 were assessed in vitro and in vivo. - Abstract: Synthetic progestins act as endocrine disrupters in fish but their risk to the environment is not sufficiently known. Here, we focused on an unexplored antiandrogenic progestin, chlormadinone acetate (CMA), and the antiandrogenic progestin cyproterone acetate (CPA). The aim was to evaluate whether their in vitro interaction with human and rainbowfish (Melanotaenia fluviatilis) sex hormone receptors is similar. Furthermore, we investigated their activity in zebrafish (Danio rerio) eleuthero-embryos. First, we studied agonistic and antagonistic activities of CMA, CPA, and 17α-ethinylestradiol (EE2), in recombinant yeast expressing either the human progesterone (PGR), androgen (AR), or estrogen receptor. The same compounds were also investigated in vitro in a stable transfection cell system expressing rainbowfish nuclear steroid receptors. For human receptors, both progestins exhibited progestogenic, androgenic and antiestrogenic activity with no antiandrogenic or estrogenic activity. In contrast, interactions with rainbowfish receptors showed no progestogenic, but antiandrogenic, antiglucocorticoid, and some antiestrogenic activity. Thus, interaction with and transactivation of human and rainbowfish PGR and AR were distinctly different. Second, we analyzed transcriptional alterations in zebrafish eleuthero‐embryos at 96 and 144 h post fertilization after exposure to CPA, CMA, EE2, and binary mixtures of CMA and CPA with EE2, mimicking the use in oral contraceptives. CMA led to slight down-regulation of the ar transcript, while CPA down-regulated ar

1984-01-01

We have studied the production of phi mesons in J/psi decays with the Mark III detector at the SPEAR e+e - storage ring. General features of inclusive phi production are discussed as well as the observation of several exclusive channels containing phi's. From a sample of 2.7 million J/psi's, we have measured the branching ratio of J/psi → phi eta to be (6.8 +- 0.6 +- 0.9) x 10 -4 and that of J/psi → phi eta' to be (3.7 +- 0.6 +- 0.6) x 10 -4 . We also present the first observation of the sequential decay J/psi → γ eta c, eta c → phi phi, and we have measured the product branching ratio to be (1.02 +- 0.25 +- 0.14) x 10 -4 . The angular distributions of the final state particles in this decay mode give the first experimental determination that the spin and parity of the eta c are 0 - . 50 references, 47 figures

Direct measurement of alpha_QED(mZ)at the FCC-ee

CERN Document Server

Janot, Patrick

2016-02-08

When the measurements from the FCC-ee become available, an improved determination of the standard-model "input" parameters will be needed to fully exploit the new precision data towards either constraining or fitting the parameters of beyond-the-standard-model theories. Among these input parameters is the electromagnetic coupling constant estimated at the Z mass scale, alpha_QED(mZ). The measurement of the muon forward- backward asymmetry at the FCC-ee, just below and just above the Z pole, can be used to make a direct determination of alpha_QED(mZ) with an accuracy deemed adequate for an optimal use of the FCC-ee precision data.

Full Text Available Background. Preeclampsia (PE is one of the most important complications of pregnancy that is associated with significant mortality and morbidity in mother and fetus. Since the etiologic factors in its development are still unclear, we aimed to examine the intercellular adhesion molecule-1 (ICAM-1 gene K469E polymorphism in preeclamptic and control healthy women. Materials and Methods. Genetic polymorphism was analyzed in 192 PE and 186 healthy control women. PCR-RFLP method was used to identify K469E polymorphism. Results. The frequency of KK, KE, and EE genotypes of ICAM-1 gene was not different between PE patients and healthy pregnant women. Whereas, the frequency of KE and EE genotypes was significantly higher in severe PE than mild PE women and control group, and the risk of severe PE was 2.4-fold higher in subjects with KE genotype (OR, 2.4 [95% CI, 1 to 5.9]; P=0.03 and 3.3-fold higher in subjects with EE genotype (OR, 3.3 [95% CI, 1.2 to 9]; P=0.015 compared to individuals with KK genotype. Conclusion. We concluded that KE and EE genotypes of K469E polymorphism could increase risk of severe PE.

A new type of precipitate (designated L-J phase) with two variants was observed within the (DO3 + L21) matrix in a Cu2.2Mn0.8Al alloy. Transmission electron microscopy examinations indicated that the L-J phase has an orthorhombic structure with lattice parameters a = 0.413 nm, b = 0.254 nm and c = 0.728 nm. The orientation relationship between the L-J phase and the matrix is (100)L-J//(011) m , (010)L-J//(111) m and (001)L-J//(211) m . The rotation axis and rotation angle between two variants of the L-J phase are [021] and 90 deg. The L-J phase has never been observed in various Cu-Al, Cu-Mn, and Cu-Al-Mn alloy systems before.

Prospects of type-II seesaw models at future colliders in light of the DAMPE e+e- excess

Science.gov (United States)

Sui, Yicong; Zhang, Yongchao

2018-05-01

The DAMPE e+e- excess at around 1.4 TeV could be explained in the type-II seesaw model with a scalar dark mater D which is stabilized by a discrete Z2 symmetry. The simplest scenario is the annihilation D D →H++H- followed by the subsequent decay H±±→e±e±, with both the DM and triplet scalars roughly 3 TeV with a small mass splitting. In addition to the Drell-Yan process at future 100 TeV hadron colliders, the doubly charged components could also be produced at lepton colliders like ILC and CLIC in the off shell mode and mediate lepton flavor violating processes e+e-→ℓi±ℓj∓ (with i ≠j ). A wide range of parameter space of the type-II seesaw could be probed, which are well below the current stringent lepton flavor constraints.

2016-09-01

We present the results of a program to map the Sh2-235 molecular cloud complex in the CO and 13CO J = 2 - 1 transitions using the Heinrich Hertz Submillimeter Telescope. The map resolution is 38″ (FWHM), with an rms noise of 0.12 K brightness temperature, for a velocity resolution of 0.34 km s-1. With the same telescope, we also mapped the CO J = 3 - 2 line at a frequency of 345 GHz, using a 64 beam focal plane array of heterodyne mixers, achieving a typical rms noise of 0.5 K brightness temperature with a velocity resolution of 0.23 km s-1. The three spectral line data cubes are available for download. Much of the cloud appears to be slightly sub-thermally excited in the J = 3 level, except for in the vicinity of the warmest and highest column density areas, which are currently forming stars. Using the CO and 13CO J = 2 - 1 lines, we employ an LTE model to derive the gas column density over the entire mapped region. Examining a 125 pc2 region centered on the most active star formation in the vicinity of Sh2-235, we find that the young stellar object surface density scales as approximately the 1.6-power of the gas column density. The area distribution function of the gas is a steeply declining exponential function of gas column density. Comparison of the morphology of ionized and molecular gas suggests that the cloud is being substantially disrupted by expansion of the H II regions, which may be triggering current star formation.

Annual Report 2001. Plataforma Solar de Almeria

International Nuclear Information System (INIS)

2002-01-01

This Annual Report for the year 2001 begins a new series in this type of document for the Plataforma Solar de Almeria. For the first time it includes activities carried out of our facilities since the withdrawal of the German Aerospace Agency (DLR) in December 1998 from the joint operation and management of the PSA. Since January, 1999, the Plataforma Solar has been managed entirely by the CIEMAT, although it continues to enjoy the considerable fruitful collaboration of DLR in a new framework of relations based on specific R and D projects of mutual interest. This new orientation, beginning in 1999 and 2000, and its results, permit us to write this report of 2001's activities optimistically, having now consolidated the new organizational structure and cleared in logical unknowns that at one time may have existed concerning the future of a facility that may be considered unique in the world. The publication of the Plan for the Promotion of Renewable Energies in Spain in December 1999, the boost received from the European Commission's 5th Framework Program R and D projects and the assistance received from the European Regional Development Fund (ERDF) and Profit programs, not to mention the decisive internal support from the CIEMAT Executive Committee, have meant that we now enjoy an undoubtedly better situation than at the beginning of this new stage. Fruit of it are the significant R and D results in the different solar concentrating technologies described in this Report and the creation of new installations, that will be enlarged during the next two years as new projects in the fields of solar thermal storage for trough collectors, solar desalination with a new field of CPC collectors or high solar flux materials treatments in the new vertical-axis furnace are begun. The imminent approval of a premium for electricity generated by solar thermal power plants, which recognizes their environmental benefit and that other renewable energies are already enjoying will mean

O fenômeno é estudado em vários países e, devido à preocupação com seus efeitos, métodos vêm sendo desenvolvidos como forma de mensuração. Neste sentido, o presente trabalho visa obter os primeiros índices de chuva dirigida direcionais para a cidade de Goiânia-GO, bem como verificar a existência de relação desse índice com a umidade medida na superfície das fachadas de um edifício multipavimentos. Para tanto, os índices de chuva dirigida direcionais (ICDd da média mensal e de janeiro foram calculados aplicando o método semi-empírico, considerando dados meteorológicos do período de 2002 a 2008. Posteriormente, foi realizada a medição experimental de umidade na superfície do revestimento das fachadas de um edifício com 17 pavimentos tipo. As medições foram realizadas sobre as fachadas revestidas com argamassa, no mês de janeiro, após um evento de precipitação pluviométrica. Como resultado, obteve-se que o ICDd da média de todos os meses dos anos analisados e o ICDd de janeiro indicam um comportamento diferenciado de chuva dirigida para cada orientação. As medições de umidade superficial nas fachadas do edifício apontaram a ocorrência de maior umedecimento para as fachadas voltadas à orientação N, bem como no pavimento mais alto (17º e nas regiões abaixo das janelas.

A comparison of the rates for ψ(2S)→π + π - J/ψ, J/ψ→l + l - and J/ψ→ anything is used to determine the J/ψ leptonic branching fractions. The results are B(J/ψ→e + e - )=(5.90±0.05±0.10)% and B(J/ψ→μ + μ - )=(5.84±0.06±0.10)%, where the first error is statistical and the second is systematic. Assuming lepton universality, the leptonic branching fraction of the J/ψ is B(J/ψ→l + l - )=(5.87±0.04±0.09)% per species. This result is used to estimate the QCD scale factor Λ MS (4) and the strong coupling constant α s . copyright 1998 The American Physical Society

An analysis of reaction products for the reaction of E,E-2,4-hexadienal with chlorine atoms (Cl) and OH and NO3 radicals has been carried out at the first time with the aim of obtaining a better understanding of the tropospheric reactivity of α,β-unsaturated carbonyl compounds. Fourier Transform Infrared (FTIR) spectroscopy and Gas Chromatography-Mass Spectrometry with a Time of Flight detector (GC-TOFMS) were used to carry out the qualitative and/or quantitative analyses. Reaction products in gas and particulate phase were observed from the reactions of E,E-2,4- hexadienal with all oxidants. E/Z-Butenedial and maleic anhydride were the main products identified in gas phase. E-butenedial calculated molar yield ranging from 4 to 10%. A significant amount of multifunctional compounds (chloro and hydroxy carbonyls) was identified. These compounds could be formed in particulate phase explaining the ∼90% of unaccounted carbon in gas phase. The reaction with Cl atoms in the presence of NOx with a long reaction time gave Peroxy Acetyl Nitrate (PAN) as an additional product, which is known for being an important specie in the generation of the photochemical smog. Nitrated compounds were the major organic products from the reaction with the NO3 radical. Based on the identified products, the reaction mechanisms have been proposed. In these mechanisms a double bond addition of the atmospheric oxidant at C4/C5 of E,E-2,4-hexadienal is the first step for tropospheric degradation.

We have measured the reactions ee → μμ and ee → tautau at center of mass energies from 9.4 to 31.6 GeV. The production cross sections are in agreement with the predictions of quantum electrodynamics, resulting in cutoff parameter limits of 70-100 GeV at 95%. The branching ratio for tau → μνanti ν has been determined as 17.8 +- 2.0 (statist.) +- 1.8 (syst.)%. The existence of a new sequential heavy lepton with a mass < 14.5 GeV is excluded at the 95% confidence Level. (orig.)

Tais estudos possibilitam a análise da produção científica para diversos propósitos e um dos desafios neste tipo de análise está na diversidade de repositórios contendo dados em formatos e estruturas distintas. Os currículos da Plataforma Lattes se caracterizam atualmente como importante ferramenta para que pesquisadores, acadêmicos e estudantes, registrem seus dados, sendo amplamente utilizados, se caracterizando como um dos maiores repositórios de dados sobre produção científica, técnica, artística e profissional, contendo milhões de pesquisadores cadastrados. Neste trabalho é proposta uma plataforma para extração de todo o conjunto de dados dos currículos Lattes compondo um grande repositório de dados científicos, além disso, são implementadas técnicas para análises bibliométricas dos dados e identificação de redes de colaboração científica. Como resultados são apresentados estudos que objetivam obter uma visão geral sobre o repositório de currículos Lattes e como o conteúdo destes currículos pode ser utilizado para a caracterização de redes de colaboração científica. Conclui-se que os currículos Lattes são uma fonte extremamente rica de dados científicos e que sua adoção para estudos bibliométricos e baseados em análise de redes cientificas podem proporcionar resultados importantes para compreensão de como a ciência brasileira tem sido realizada. A grande dificuldade ao se analisar todo o repositório de dados da Plataforma Lattes está relacionada ao grande volume de dados que a compõem e ainda devido ao uso de técnicas, como por exemplo de identificação de colaborações pouco eficientes e computacionalmente complexas.

This letter describes a direct search for pair produced magnetic monopoles in e+e- collisions. The analysis is based on 62.7 pb^-1 of data collected with the OPAL detector at an average centre-of-mass energy of sqrt(s)= 206.3GeV. The monopole signal was assumed to be characterized by two back-to-back particles with an anomalously high ionization energy loss de/dx in the tracking chambers. No evidence for production of monopoles was observed. Upper limits were obtained on the magnetic monopole pair-production cross-section (sigma) in the mass range 45 GeV/c^22. The average limit is sigma < 0.05 pb and is essentially independent of the magnetic monopole mass. The cross-section limit is derived at the 95% confidence level and is valid for spin-1/2 magnetic monopoles.

Educational Entrepreneurship (EE: Delineating and Highlighting Its Domain, Importance and Feasibility in Uganda’s Context

Full Text Available Although in many countries government financial support for education is dwindling, not many educational institutions have succeeded in devising internal mechanisms and practices to enable them to continuously deliver quality education in quantity. Might the application of certain entrepreneurial strategies in educational management perhaps help to make a difference? What is educational entrepreneurship (EE? How feasible is EE in a developing world education landscape like that of Uganda? Which challenges must EE surmount before it can envisage success? Using literature review methodology, this study attempted to find answers to such questions. Its aim was to delineate the EE domain and to highlight both its importance and feasibility in Uganda’s context. The study makes two important revelations; first, that indeed EE is clouded in conceptual mishmash, hence need for more scholarly attention on the subject; second, that however salvaging EE can be to struggling educational institutions, it is not without challenges – even apparent contradictions – hence preference for a “moderate risk” approach to entrepreneurship within educational institutions.

We present fully sampled 38'' resolution maps of the CO and 13 CO J = 2-1 lines in the molecular clouds toward the H II region complex W3. The maps cover a 2. 0 0 x 1. 0 67 section of the galactic plane and span -70 to -20 km s -1 (LSR) in velocity with a resolution of ∼1.3 km s -1 . The velocity range of the images includes all the gas in the Perseus spiral arm. We also present maps of CO J = 3-2 emission for a 0. 0 5 x 0. 0 33 area containing the H II regions W3 Main and W3(OH). The J = 3-2 maps have velocity resolution of 0.87 km s -1 and 24'' angular resolution. Color figures display the peak line brightness temperature, the velocity-integrated intensity, and velocity channel maps for all three lines, and also the (CO/ 13 CO) J = 2-1 line intensity ratios as a function of velocity. The line intensity image cubes are made available in standard FITS format as electronically readable files. We compare our molecular line maps with the 1.1 mm continuum image from the BOLOCAM Galactic Plane Survey (BGPS). From our 13 CO image cube, we derive kinematic information for the 65 BGPS sources in the mapped field, in the form of Gaussian component fits.

At the moment, the marine platforms are being designed with CAD tools, reason why before its installation they have a 3D model, which is updated as the design advances, until arriving at the approved version for construction. Later, the digital model of the marine platform serves to guide in the construction and follow up the advance of the same. Similarly, the model 3D is due to update with respect to the changes that arise during the construction and installation, until the commissioning of the platform, nevertheless, many of these were constructed when these tools were not yet available, reason why it becomes necessary to construct the digital model according to the present condition they exhibit. In order to develop the digital model of the marine platforms in operation, the activities are grouped in three large stages: specification of scope, retrieval of the information and modeling.

The ratio of the electron and muon widths of the J/ψ meson has been measured using direct J/ψ decays in the KEDR experiment at the VEPP-4M electron–positron collider. The result Γ{sub e{sup +}e{sup −}}(J/ψ)/Γ{sub μ{sup +}μ{sup −}}(J/ψ)=1.0022±0.0044±0.0048(0.65%) is in good agreement with the lepton universality. The experience collected during this analysis will be used for J/ψ lepton width determination with up to 1% accuracy.

Bose-Fermi U(6/2j+1) supersymmetries and high-spin anomalies

International Nuclear Information System (INIS)

Morrison, I.; Jarvis, P.D.

1985-01-01

A supersymmetric extension of the interacting boson model (IBM) is constructed to describe high-spin anomalies in both even- and odd-mass spectra of the Hg, Pt region (190<=A<=200). Supergroup chains such as U(6/2j+1)containsOsp(6/2j+1)containsO(6)xSp(2j+1)... or U(6/2j+1)containsU(5/2j+1)xU(1)containsOsp(5/2j+1)... incorporate a single j-shell fermion in addition to the usual 's' and 'd' bosons (L=0 and L=2). The orthosympletic supergroup reflects the strong pairing force in the subspace of the fermion intruder level. The model agrees favourably with experiment and microscopic calculation. (orig.)

The J-2X Fuel Turbopump - Design, Development, and Test

Pratt and Whitney Rocketdyne (PWR), a NASA subcontractor, is executing the design, development, test, and evaluation (DDT&E) of a liquid oxygen, liquid hydrogen two hundred ninety four thousand pound thrust rocket engine initially intended for the Upper Stage (US) and Earth Departure Stage (EDS) of the Constellation Program Ares-I Crew Launch Vehicle (CLV). A key element of the design approach was to base the new J-2X engine on the heritage J-2S engine with the intent of uprating the engine and incorporating SSME and RS-68 lessons learned. The J-2S engine was a design upgrade of the flight proven J-2 configuration used to put American astronauts on the moon. The J-2S Fuel Turbopump (FTP) was the first Rocketdyne-designed liquid hydrogen centrifugal pump and provided many of the early lessons learned for the Space Shuttle Main Engine High Pressure Fuel Turbopumps. This paper will discuss the design trades and analyses performed for the current J-2X FTP to increase turbine life; increase structural margins, facilitate component fabrication; expedite turbopump assembly; and increase rotordynamic stability margins. Risk mitigation tests including inducer water tests, whirligig turbine blade tests, turbine air rig tests, and workhorse gas generator tests characterized operating environments, drove design modifications, or identified performance impact. Engineering design, fabrication, analysis, and assembly activities support FTP readiness for the first J-2X engine test scheduled for July 2011.

We report the first search for CP-violating decays of the Υ(4S) using a data sample that contains 535×106 Υ(4S) mesons with the Belle detector at the KEKB asymmetric-energy e+e- collider. A partial reconstruction technique is employed to enhance the signal sensitivity. No significant signals were observed. We obtain an upper limit of 4×10-7 at the 90% confidence level for the branching fractions of the CP violating modes, Υ(4S)→B0B¯0→J/ψKS0+J/ψ(ηc)KS0. Extrapolating the result, we find that an observation with 5σ significance is expected with a 30ab-1 data sample, which is within the reach of a future super B factory.

Ground-state ordering of the J1-J2 model on the simple cubic and body-centered cubic lattices

Science.gov (United States)

Farnell, D. J. J.; Götze, O.; Richter, J.

2016-06-01

The J1-J2 Heisenberg model is a "canonical" model in the field of quantum magnetism in order to study the interplay between frustration and quantum fluctuations as well as quantum phase transitions driven by frustration. Here we apply the coupled cluster method (CCM) to study the spin-half J1-J2 model with antiferromagnetic nearest-neighbor bonds J1>0 and next-nearest-neighbor bonds J2>0 for the simple cubic (sc) and body-centered cubic (bcc) lattices. In particular, we wish to study the ground-state ordering of these systems as a function of the frustration parameter p =z2J2/z1J1 , where z1 (z2) is the number of nearest (next-nearest) neighbors. We wish to determine the positions of the phase transitions using the CCM and we aim to resolve the nature of the phase transition points. We consider the ground-state energy, order parameters, spin-spin correlation functions, as well as the spin stiffness in order to determine the ground-state phase diagrams of these models. We find a direct first-order phase transition at a value of p =0.528 from a state of nearest-neighbor Néel order to next-nearest-neighbor Néel order for the bcc lattice. For the sc lattice the situation is more subtle. CCM results for the energy, the order parameter, the spin-spin correlation functions, and the spin stiffness indicate that there is no direct first-order transition between ground-state phases with magnetic long-range order, rather it is more likely that two phases with antiferromagnetic long range are separated by a narrow region of a spin-liquid-like quantum phase around p =0.55 . Thus the strong frustration present in the J1-J2 Heisenberg model on the sc lattice may open a window for an unconventional quantum ground state in this three-dimensional spin model.

Genetic Algorithm Applied to the Eigenvalue Equalization Filtered-x LMS Algorithm (EE-FXLMS

Directory of Open Access Journals (Sweden)

Stephan P. Lovstedt

2008-01-01

Full Text Available The FXLMS algorithm, used extensively in active noise control (ANC, exhibits frequency-dependent convergence behavior. This leads to degraded performance for time-varying tonal noise and noise with multiple stationary tones. Previous work by the authors proposed the eigenvalue equalization filtered-x least mean squares (EE-FXLMS algorithm. For that algorithm, magnitude coefficients of the secondary path transfer function are modified to decrease variation in the eigenvalues of the filtered-x autocorrelation matrix, while preserving the phase, giving faster convergence and increasing overall attenuation. This paper revisits the EE-FXLMS algorithm, using a genetic algorithm to find magnitude coefficients that give the least variation in eigenvalues. This method overcomes some of the problems with implementing the EE-FXLMS algorithm arising from finite resolution of sampled systems. Experimental control results using the original secondary path model, and a modified secondary path model for both the previous implementation of EE-FXLMS and the genetic algorithm implementation are compared.

BPH/2J mice are a genetic model of hypertension associated with an overactive sympathetic nervous system. Orexin is a neuropeptide which influences sympathetic activity and blood pressure. Orexin precursor mRNA expression is greater in hypothalamic tissue of BPH/2J compared with normotensive BPN/3J mice. To determine whether enhanced orexinergic signaling contributes to the hypertension, BPH/2J and BPN/3J mice were preimplanted with radiotelemetry probes to compare blood pressure 1 hour before and 5 hours after administration of almorexant, an orexin receptor antagonist. Mid frequency mean arterial pressure power and the depressor response to ganglion blockade were also used as indicators of sympathetic nervous system activity. Administration of almorexant at 100 (IP) and 300 mg/kg (oral) in BPH/2J mice during the dark-active period (2 hours after lights off) markedly reduced blood pressure (-16.1 ± 1.6 and -11.0 ± 1.1 mm Hg, respectively;PBPH/2J mice (PBPH/2J mice have 29% more orexin neurons than BPN/3J mice which are preferentially located in the lateral hypothalamus. The results suggest that enhanced orexinergic signaling contributes to sympathetic overactivity and hypertension during the dark period in BPH/2J mice. © 2016 American Heart Association, Inc.

A search for high-mass resonances in the e+e- final state is presented based on 2.5 fb(-1) of sqrt[s]=1.96 TeV pp collision data from the CDF II detector at the Fermilab Tevatron. The largest excess over the standard model prediction is at an e+e- invariant mass of 240 GeV/c2. The probability of observing such an excess arising from fluctuations in the standard model anywhere in the mass range of 150-1000 GeV/c2 is 0.6% (equivalent to 2.5sigma). We exclude the standard model coupling Z' and the Randall-Sundrum graviton for k/MPl=0.1 with masses below 963 and 848 GeV/c2 at the 95% credibility level, respectively.

We study the potential of future lepton colliders to probe violation of the CP symmetry in the top quark sector. In certain extensions of the Standard Model, such as the two-Higgs-doublet model (2HDM), sizeable anomalous top quark dipole moments can arise, that may be revealed by a precise measurement of top quark pair production. We present results from detailed Monte Carlo studies for the ILC at 500 GeV and CLIC at 380 GeV and use parton level simulations to explore the potential of high-energy operation. We find that precise measurements in $e^+e^- \\rightarrow t \\bar{t}$ production with subsequent decay to lepton plus jets final states can provide sufficient sensitivity to detect Higgs-boson-induced CP violation in a viable two-Higgs-doublet model. The potential of a linear $e^+e^-$ collider to detect CP-violating electric and weak dipole form factors of the top quark exceeds the prospects of the HL-LHC by over an order of magnitude.

Ab Initio f values for Fe II J=9/2 ->9/2^o transitions

Science.gov (United States)

Beck, Donald

2005-05-01

Relativistic configuration interaction f values have been obtained for 264 transitions between the lowest 12 J=9/2 and the 22 J=9/2^o levels. Length and velocity gauges agree to 3.8% for in-shell transitions and 10.0% for shell jump transitions. Two J=9/2^o levels are so nearly degenerate that it was necessary to introduce a semi-empirical correction to produce the correct level ordering. The results are in overall good agreement with the semi-empirical results of Kurucz ootnotetextR. L. Kurucz, http://kurucz.harvard.edu/atoms/2601/ and Raassen ootnotetextA. J. J. Raasen, ftp://ftp.wins.uva.nl/pub/orth/iron/FeII.E1 (1999). An efficient method of including magnetic Breit effects in the energy matrix is presented.

The cross sections and forward-backward asymmetries of hadronic and leptonic events produced in e+e- collisions at centre-of-mass energies of 130-183 GeV are presented. Results for ee, mumu, tautau, qq, bb and cc production show no significant deviation from the Standard Model predictions. This enable constraints to be set upon physics beyond the Standard Model such as four-fermion contact interactions, leptoquarks, Z' bosons and R-parity violating squarks and sneutrinos. Limits on the energy scale Lambda of eeff contact interactions are typically in the range from 2-10 TeV. Limits on R-parity violating sneutrinos reach masses of a few hundred GeV for large values of their Yukawa couplings.

Flavour inclusive, udsc and b fragmentation functions in unbiased jets, and flavour inclusive, udsc, b and gluon fragmentation functions in biased jets are measured in e+e- annihilations from data collected at centre-of-mass energies of 91.2, and 183-209 GeV with the OPAL detector at LEP. The unbiased jets are defined by hemispheres of inclusive hadronic events, while the biased jet measurements are based on three-jet events selected with jet algorithms. Several methods are employed to extract the fragmentation functions over a wide range of scales. Possible biases are studied in the results are obtained. The fragmentation functions are compared to results from lower energy e+e- experiments and with earlier LEP measurements and are found to be consistent. Scaling violations are observed and are found to be stronger for the fragmentation functions of gluon jets than for those of quarks. The measured fragmentation functions are compared to three recent theoretical next-to-leading order calculations and to the p...

Proceedings, High-Precision $\\alpha_s$ Measurements from LHC to FCC-ee

Energy Technology Data Exchange (ETDEWEB)

d' Enterria, David [CERN; Skands, Peter Z. [Monash U.

2015-01-01

This document provides a writeup of all contributions to the workshop on "High precision measurements of $\\alpha_s$: From LHC to FCC-ee" held at CERN, Oct. 12--13, 2015. The workshop explored in depth the latest developments on the determination of the QCD coupling $\\alpha_s$ from 15 methods where high precision measurements are (or will be) available. Those include low-energy observables: (i) lattice QCD, (ii) pion decay factor, (iii) quarkonia and (iv) $\\tau$ decays, (v) soft parton-to-hadron fragmentation functions, as well as high-energy observables: (vi) global fits of parton distribution functions, (vii) hard parton-to-hadron fragmentation functions, (viii) jets in $e^\\pm$p DIS and $\\gamma$-p photoproduction, (ix) photon structure function in $\\gamma$-$\\gamma$, (x) event shapes and (xi) jet cross sections in $e^+e^-$ collisions, (xii) W boson and (xiii) Z boson decays, and (xiv) jets and (xv) top-quark cross sections in proton-(anti)proton collisions. The current status of the theoretical and experimental uncertainties associated to each extraction method, the improvements expected from LHC data in the coming years, and future perspectives achievable in $e^+e^-$ collisions at the Future Circular Collider (FCC-ee) with $\\cal{O}$(1--100 ab$^{-1}$) integrated luminosities yielding 10$^{12}$ Z bosons and jets, and 10$^{8}$ W bosons and $\\tau$ leptons, are thoroughly reviewed. The current uncertainty of the (preliminary) 2015 strong coupling world-average value, $\\alpha_s(m_Z)$ = 0.1177 $\\pm$ 0.0013, is about 1\\%. Some participants believed this may be reduced by a factor of three in the near future by including novel high-precision observables, although this opinion was not universally shared. At the FCC-ee facility, a factor of ten reduction in the $\\alpha_s$ uncertainty should be possible, mostly thanks to the huge Z and W data samples available.

Explaining the DAMPE e+e- excess using the Higgs triplet model with a vector dark matter

Science.gov (United States)

Chen, Chuan-Hung; Chiang, Cheng-Wei; Nomura, Takaaki

2018-03-01

We explain the e+e- excess observed by the DAMPE Collaboration using a dark matter model based upon the Higgs triplet model and an additional hidden S U (2 )X gauge symmetry. Two of the S U (2 )X gauge bosons are stable due to a residual discrete symmetry and serve as the dark matter candidate. We search the parameter space for regions that can explain the observed relic abundance, and compute the flux of e+e- coming from a nearby dark matter subhalo. With the inclusion of background cosmic rays, we show that the model can render a good fit to the entire energy spectrum covering the AMS-02, Fermi-LAT, CALET and DAMPE data.

We present a first rough estimate for the electrical power consumption of the FCC-ee lepton collider. This electrical power is dominated by the RF system, which provides the motivation for the ongoing R&D on highly efficient RF power sources. Other contributions come from the warm arc magnets, the cryogenics systems, cooling, ventilation, general services, the particle-physics detectors, and the injector complex.

Analysis of the J /ψ →π0γ* transition form factor

Science.gov (United States)

Kubis, Bastian; Niecknig, Franz

2015-02-01

In view of the first measurement of the branching fraction for J /ψ →π0e+e- by the BESIII collaboration, we analyze what can be learned on the corresponding transition form factor using dispersion theory. We show that light-quark degrees of freedom dominate the spectral function, in particular two-pion intermediate states. Estimating the effects of multipion states as well as charmonium, we arrive at a prediction for the complete form factor that should be scrutinized experimentally in the future.

Full Text Available Non-directed interviews constitute the main data collection instrument in qualitative health research. Studies in which this is evident are well documented in international literature. For health professionals, knowing what people feel and imagine makes it possible to develop a more adequate clinician-patient relationship. It is indispensable to know what the life phenomena mean for individuals, because the meanings have a structuring function. People organize their lives around the meaning they attribute to situations or object. This is also relevant to their health care. From research conducted at the Laboratory of Clinical-Qualitative Research, State University of Campinas, Campinas (São Paulo, Brazil, the authors address, in this article, the following matters: characterization of non-directed interviews, directiveness of interviews, approach techniques, observation of non-verbal and paraverbal manifestations, registry techniques / speech transcription, and validity/reliability of non-directed interviews. This is useful for people interested in research at graduate and undergraduate level.Las entrevistas no-dirigidas constituyen el principal instrumento de colecta de datos de la investigación cualitativa en el campo de la salud. Estos estudios están consolidados en la literatura internacional. Para los profesionales de salud, saber lo que sienten e imaginan las personas contribuye para la construcción de una relación medico-paciente mas adecuada. Es indispensable saber el significado de los fenómenos de la vida para los individuos, porque tiene una función estructurante: alrededor de lo que significan organizamos nuestras vidas, incluyendo los cuidados con nuestra salud. A partir de investigaciones realizadas en el Laboratorio de Investigación Clínico-Cualitativa, Universidad Estatal de Campinas, Brasil, los autores tratan de: caracterización de entrevistas no-dirigidas, continuum directivo de entrevistas, técnicas del

Full Text Available El objetivo de este trabajo fue indagar la existencia de diferentes "grupos" de jóvenes en función de sus representaciones alrededor de la salud y la enfermedad. En la construcción de estos "grupos" se busca incorporar conceptos tradicionalmente relegados al estudio de la subjetividad. Se trabajó con una encuesta cerrada que se aplicó sobre 400 jóvenes escolarizados. El procesamiento de los datos se realizó con el análisis de correspondencias múltiples, una técnica de análisis multivariado especialmente diseñada para trabajar con un alto número de variables cualitativas. El estudio permitió despejar ocho "tipos" de jóvenes ­ los asustados, los que cierran los ojos, los hipocondríacos, los sensuales, los felices, los amargados, los que miran al mundo y los que miran su ombligo. Estos resultados indicarían la necesidad de diversificar las estrategias de indagación e intervención en terreno dirigidas a esta población.

Extended commutator method for boson mapping in the seniority scheme: Two non-degenerate-j shells with vertical strokej1-j2vertical stroke=2

International Nuclear Information System (INIS)

Bonatsos, D.; Klein, A.

1987-01-01

The commutator method of Bonatsos, Klein and Li for approximate boson mapping in the seniority scheme, previously illustrated for the single-j shell-model algebra SO(2(2j+1)), has been extended in order to be applicable to the case of many non-degenerate-j shells, and the physically interesting case of two shells with vertical strokej 1 -j 2 vertical stroke=2 has been studied in detail. The most important new feature of this work is that bosons corresponding to pairs of two fermions each of which belongs to a different shell have been included in the calculation. (These bosons had been omitted in previous work using the Otsuka-Arima-Iachello method.) The calculation is successively carried out to lowest and to next-higher order, the latter exhibiting the necessity of including f- and g-bosons (both of positive parity) in the calculation in order to reach algebraic consistency.

Fragmentation contributions to hadroproduction of prompt $J/\\psi$, $\\chi_{cJ}$, and $\\psi(2S)$ states

Chung, Hee Sok

2016-01-01

We compute leading-power fragmentation corrections to hadroproduction of charmonium states J/ψ, χcJ , and ψ(2S) in the nonrelativistic QCD factorization formalism. We include fragmentation functions through order α 2 s and parton production cross sections through order α 3 s . We also resum leading logarithms of the transverse momentum divided by the charm-quark mass to all orders in αs . We find that the fragmentation corrections have a significant impact on the hadroproduction cross section of charmonia. We obtain good fits to the hadroproduction cross sections measured at the Tevatron and the LHC. Using the long-distance matrix elements obtained from the fits, we make predictions for prompt J/ψ polarization that are in good agreement with the LHC data.

2017-09-01

The Visible/Infrared Imaging Radiometer Suite (VIIRS) is a key sensor on the Suomi National Polar-orbiting Partnership (NPP) satellite as well as the upcoming Joint Polar Satellite System (JPSS). VIIRS collects Earth radiometric and imagery data in 22 spectral bands from 0.4 to 12.5 μm. Radiometric calibration of the reflective bands in the 0.4 to 2.5 μm wavelength range is performed by measuring the sunlight reflectance from Spectralon®. Reflected sun light is directly proportional to the Bidirectional Reflectance Distribution Function (BRDF) of the Spectralon. This paper presents the BRDF measurements of the Spectralon for JPSS J2 in the 0.4 - 1.63 μm wavelength using PASCAL (Polarization And Scatter Characterization Analysis of Lambertian materials) with an uncertainty better than 1.2%. PASCAL makes absolute measurements of the BRDF in an analogous fashion to the National Institute of Standards and Technology (NIST) Spectral Tri-function Automated Reflectance Reflectometer (STARR) facility. Unique additional features of this instrument include the ability to vary the sample elevation and roll / clock the sample about its normal, allowing measurement of BRDF in the as used geometry. Comparison of BRDF in the as used configuration for NPP, J1, and J2 shows variation of up to 3%. The sign of the change from panel to panel depends on the angle of incidence and view angle. The results demonstrate lot to lot variability in Spectralon and emphasize the necessity of characterizing each panel. A pattern in the BRDF variation is also presented.

Analysis of the accelerometer system response to 11 microseismic events created in Experiment 2007 indicates that they are located in an ellipsoidal volume whose major axis direction is N 48° E and dips 47° to the SW. The intermediate axis is essentially horizontal and whose direction N 42° W is the strike of the plane containing the two major axes. The dimensions of the three axes are 315,100 and 65 m respectively. The relationship of this seismic feature to the downhole wellbore map is shown in Figures 1 and 2. It will be noted that the ellipsoid is tangent to the injection point in EE-3 and descends at a 45 angle. The plan view shown in Figure 1 indicates that the zone of seismic activity nearly cut the EE-2 wellbore at a depth of 11500 ft (TVD). Examination of the EE-2 wellbore geology and drilling history shows a well defined zone from 11450-11550 ft TVD with a very fast drilling rate (30 ft/hr) and extensive alteration. Laney labels it as a fault zone. This then coudl be an unpressurized part of the planar feature described above.

BPH/2J hypertensive mice have an exaggerated sympathetic contribution to blood pressure (BP). Premotor sympathetic neurons within the rostroventrolateral medulla (RVLM) are a major source of sympathetic vasomotor tone and major site of action of the centrally acting sympatholytic agent, rilmenidine. The relative cardiovascular effect of rilmenidine in BPH/2J versus normotensive BPN/3J mice was used as an indicator of the involvement of the RVLM in the sympathetic contribution to hypertension in BPH/2J mice. BPH/2J and BPN/3J mice were pre-implanted with telemetry devices to measure BP in conscious unrestrained mice. Rilmenidine was administered acutely (n=7-9/group), orally for 14 days, at a wide range of doses (n=5/group), and also infused intracerebroventricularly for 7 days (n=6/group). Acute intraperitoneal rilmenidine induced greater depressor and bradycardic responses in BPH/2J than BPN/3J mice (PstrainBPH/2J mice during the dark (active) period (-6.5 ± 2 mmHg; P=0.006). Chronic orally administered rilmenidine (1-12 mg/kg per day) also had minimal effect on 24-h BP in both strains (P>0.16). The sympathetic vasomotor inhibitory effect of rilmenidine is minimal in both strains and similar in hypertensive BPH/2J and BPN/3J mice. Thus, hypertension in BPH/2J mice is not likely mediated by greater neuronal activity in the RVLM, and agents such as rilmenidine would be an ineffective treatment for this form of neurogenic hypertension.

Experimental study of single-vertex $(e^{-}-e^{+})$ pair creation in a crystal

CERN Multimedia

2002-01-01

This experiment will study the newly predicted process of $e^{-}-e^{+}$ pair production by high energy photons incident along major axial direction of a single crystal. This process is based upon the well-known channeling properties of negatively charged particles along atomic rows of a crystal. The $e^{-}-e^{+}$ pair creation may proceed in a one-step process, without violating energy and momentum conversation laws, due to the lowering of the total energy of the channeled electron (Fig. 1). \\\\ \\\\ The pair creation rate should increase with increasing photon energies (above a threshold of a few GeV) and largely exceed the Bethe-Heitler process rate for photon energies of a few tens of GeV. It is also expected that the created particles share the photon energy nearly equally, in contrast with the rather flat energy distribution associated with the Bethe-Heitler process. \\\\ \\\\ The experimental set-up (Fig. 2) is designed for the study of those two features: photon energy dependence of the pair creation rate, an...

Events with a final state consisting of two or more photons and large missing transverse energy have been observed in e+e- collisions at centre-of-mass energies in the range 192 - 209 GeV using the OPAL detector at LEP. Cross-section measurements are performed within the kinematic acceptance of the selection and compared with the expectation from the Standard Model process e+e- -> nu nu gamma gamma(gamma). No evidence for new physics contributions to this final state is observed. Upper limits on sigma (e+e- -> XX) BR^2(X -> Ygamma) are derived for the case of stable and invisible Y. In the case of massive Y the combined limits obtained from all the data range from 10 fb to 60 fb, while for the special case of massless Y the range is 20 fb to 40 fb. The limits apply to pair production of excited neutrions (X=nu^*,Y=nu), to neutralino production (X=~chi^0_2, Y=~chi^0_1) and to supersymmetric models in which X=~chi^0_1 and Y=~G is a light gravitino.

The FCC-ee Interaction Region Magnet Design

The design of the region close to the interaction point of the FCC-ee experiments is especially challenging. The beams collide at an angle (+-15 mrad) in the high-field region of the detector solenoid. Moreover, the very low vertical beta_y* of the machine necessitates that the final focusing quadrupoles have a distance from the IP (L*) of around 2 m and therefore are inside the main detector solenoid. The beams should be screened from the effect of the detector magnetic field, and the emittance blow-up due to vertical dispersion in the interaction region should be minimized, while leaving enough space for detector components. Crosstalk between the two final focus quadrupoles, only about 6 cm apart at the tip, should also be minimized.

The mouse mutant ducky and its allele ducky(2J) represent a model for absence epilepsy characterized by spike-wave seizures and cerebellar ataxia. These mice have mutations in Cacna2d2, which encodes the alpha2delta-2 calcium channel subunit. Of relevance to the ataxic phenotype, alpha2delta-2 mRNA is strongly expressed in cerebellar Purkinje cells (PCs). The Cacna2d2(du2J) mutation results in a 2 bp deletion in the coding region and a complete loss of alpha2delta-2 protein. Here we show that du(2J)/du(2J) mice have a 30% reduction in somatic calcium current and a marked fall in the spontaneous PC firing rate at 22 degrees C, accompanied by a decrease in firing regularity, which is not affected by blocking synaptic input to PCs. At 34 degrees C, du(2J)/du(2J) PCs show no spontaneous intrinsic activity. Du(2J)/du(2J) mice also have alterations in the cerebellar expression of several genes related to PC function. At postnatal day 21, there is an elevation of tyrosine hydroxylase mRNA and a reduction in tenascin-C gene expression. Although du(2J)/+ mice have a marked reduction in alpha2delta-2 protein, they show no fall in PC somatic calcium currents or increase in cerebellar tyrosine hydroxylase gene expression. However, du(2J)/+ PCs do exhibit a significant reduction in firing rate, correlating with the reduction in alpha2delta-2. A hypothesis for future study is that effects on gene expression occur as a result of a reduction in somatic calcium currents, whereas effects on PC firing occur as a long-term result of loss of alpha2delta-2 and/or a reduction in calcium currents and calcium-dependent processes in regions other than the soma.

In the case of massive Y the combined limits obtained from all the data range from 10 to 60 fb, while for the special case of massless Y the range is 20 to 40 fb. The limits apply to pair production of excited neutrinos (X= nu *, Y= nu ), to neutralino production (X= chi /sub 2//sup 0/, Y= chi /sub 1//sup 0/ and to supersymmetric models in which X= chi /sub 1//sup 0/ and Y=G is a light gravitino.

Highlights: • A serial of MgB_2 superconducting films from 10 nm to 8 µm have been prepared. • T_c and J_c (5 K, 0 T) of films are high. • J_c (5 K, 0 T) reaches its maximum 2.3 × 10"8 A cm"−"2 for 100 nm films. • The relationship between thickness and J_c has been discussed in detail. - Abstract: MgB_2 superconducting films, whose thicknesses range from 10 nm to 8 µm, have been fabricated on SiC substrates by hybrid physical–chemical vapor deposition (HPCVD) method. It is the first time that the T_c and the J_c of MgB_2 films are studied on such a large scale. It is found that with the increasing of thickness, T_c elevates first and then keeps roughly stable except for some slight fluctuations, while J_c (5 K, 0 T) experiences a sharp increase followed by a relatively slow fall. The maximum J_c (5 K, 0 T) = 2.3 × 10"8 A cm"−"2 is obtained for 100 nm films, which is the experimental evidence for preparing high-quality MgB_2 films by HPCVD method. Thus, this work may provide guidance on choosing the suitable thickness for applications. Meanwhile, the films prepared by us cover ultrathin films, thin films and thick films, so the study on them will bring a comprehensive understanding of MgB_2 films.

Full Text Available Durante a colheita do arroz irrigado ocorrem perdas e danos físicos e fisiológicos às sementes. No final da década de oitenta, surgiram as plataformas recolhedoras, que retiram ou arrancam o grão ao invés de cortar a panícula, porém, pouco se conhece a respeito dos danos físicos e fisiológicos que este sistema de plataforma pode causar às sementes. Este trabalho teve por objetivo avaliar os danos mecânicos causados às sementes dos cultivares de arroz BR-IRGA 409 e BR-IRGA 410, por três formas de colheita: (a colheita manual e trilha mecânica; (b colheita com plataforma de corte; (c colheita com plataforma recolhedora. Quando a colheita foi mecânica, realizou-se a coleta das amostras diretamente no graneleiro. O delineamento experimental foi blocos ao acaso, com seis repetições. Os resultados demonstraram que as sementes de arroz irrigado dos cultivares estudados não apresentaram diferenças significativas em suas qualidades físicas e fisiológicas, quando colhidas com plataforma de corte e com a plataforma recolhedora. Estes dois métodos de colheita, porém, apresentaram danos significativamente maiores quando comparados à colheita manual e trilha mecânica.During irrigated rice harvesting occur losses and physical and phisiological seed damage. Late 80's, appeared the strippers headers that strip the grain, instead of cutting the spike. However, little is know about physical and phisiological seed damage by harvest header. The objective of this work was to evaluate the mechanical damage caused to BR-IRGA 409 and BR-IRGA 410 rice cultivars by three harvesting methods: (a manual harvesting and mechanical strip; (b cutterbar harvesting and; (c stripper header harvesting. Samples were collected directly in the grain tank when the harvest was mechanical. The experimental design was randomized blocks with six replications. Results demonstrated that the rice seeds of the studied variety didn't showed significant differences in

Revisiting the Gamma-Ray Source 2FGL J1823.8+4312

One of the great challenges of gamma-ray astronomy is identifying the lower energy counterparts to these high-energy sources. Recently, in this journal, Massaro et al. attempted to find the counterpart of 2FGL J1823.8+4312, a gamma-ray active galactic nucleus (AGN) of uncertain type from the Second Fermi Large Area Telescope catalog. After considering mid-infrared data in the field from the Wide-field Infrared Survey Explorer (WISE), those authors conclude that the preferred identification of 2FGL J1823.8+4312 is WISE J182352.33+431452.5, despite the fact that the mid-infrared source is undetected at radio energies. They claim that WISE J182352.33+431452.5 constitutes the discovery of a new class of extragalactic X-ray source, either a radio-faint blazar or the prototype of a new class of active galaxy with an enigmatic spectral energy distribution. This conclusion is claimed to be independent of whether or not the WISE source is the actual counterpart to 2FGL J1823.8+4312. Based on a re-analysis of public data in this field and new spectroscopy from Palomar, we conclude that WISE J182352.33+431452.5 is a dust-reddened quasar at z = 0.560, a representative example of a very common extragalactic AGN class. Were WISE J182352.33+431452.5 to be associated with the gamma-ray emission, this would be an unusual and exciting discovery. However, we argue that 2FGL J1823.8+4312 is more likely associated with either WISE J182409.25+431404.7 or, more likely, WISE J182419.04+430949.6, two radio-loud sources in the field. The former is a radio-loud quasar and the latter is an optically variable source with a featureless blue spectrum.

Full Text Available La utilización de materiales ligeros y resistentes ha permitido la construcción de sistemas de entrepisos que satisfacen condiciones ideales espaciales y geométricas para albergar grandes cantidades de personas. A pesar que estas características de peso y resistencia representan una disminución de costos en la construcción, estos entrepisos tienden a ser más susceptibles a presentar problemas de vibraciones, especialmente cuando la excitación puede ser clasificada como actividad rítmica. En este artículo se presenta la caracterización de cargas producidas por personas realizando actividades de baile, a partir de mediciones en una plataforma experimental de escala real. Se identifican los factores de impacto y coeficientes de Fourier que representan la carga debida a personas que bailan, a la que es sometida la estructura.

Seniority-conserving forces and USp(2j+1) partial dynamical symmetry

2003-01-01

A quasispin tensor decomposition of the two-nucleon interaction determines the most general seniority-conserving rotationally invariant two-body interaction in a j shell. Such interactions define solvable and partially solvable shell model Hamiltonians for which the unitary symplectic algebra USp(2j+1) provides a complete set of quantum numbers for a subset of states. The matrix elements of seniority-conserving interactions are deduced from the matrix elements of USp(2j+1) operators. A new and powerful numerical technique is presented for computing irreps of the USp(2j+1) algebra. Applications are reported for the low-energy spectra of N=50 and N=126 isotones. The effects of including seniority nonconserving interactions are investigated

The mouse mutant ducky and its allele ducky2J represent a model for absence epilepsy characterized by spike-wave seizures, and cerebellar ataxia. These mice have mutations in Cacna2d2, which encodes the α2δ-2 calcium channel subunit. Of relevance to the ataxic phenotype, α2δ-2 mRNA is strongly expressed in cerebellar Purkinje cells (PCs). The Cacna2d2du2J mutation results in a two base-pair deletion in the coding region and a complete loss of α2δ-2 protein. Here we show that du2J/du2J mice have a 30% reduction in somatic calcium current, and a marked fall in the spontaneous PC firing rate at 22°C, accompanied by a decrease in firing regularity, which is not affected by blocking synaptic input to PCs. At 34°C du2J/du2J PCs show no spontaneous intrinsic activity. Du2J/du2J mice also have alterations in the cerebellar expression of several genes related to PC function. At P21 there is an elevation of tyrosine hydroxylase mRNA and a reduction in tenascin-C gene expression. Although du2J/+ mice have a marked reduction in α2δ-2 protein, they show no fall in PC somatic calcium currents or increase in cerebellar tryrosine hydroxylase gene expression. However, du2J/+ PCs do exhibit a significant reduction in firing rate, correlating with the reduction in α2δ-2. A hypothesis for future study is that effects on gene expression occur as a result of a reduction in somatic calcium currents, whereas effects on PC firing occur as a long-term result of loss of α2δ-2 and/or a reduction in calcium currents and calcium-dependent processes in regions other than the soma.

FCC-ee Pre-Booster Accelerators

CERN’s ambitious new project, Future Circular Collider-ee, will have four operations as Z, W, H, and tt factories covering energies from 45.6 to 175 GeV. The main challenge of Z-operation is to achieve currents as high as 1450 mA; this will depend heavily on the injector. For this reason, we conclude that we need a high bunch charge of 3.3 × 1010, for both e− and e+, and fill 91 500 of each of those bunches into the collider. To achieve the goal, we have designed an S-band (2.856 GHz) normal conducting electron linac up to 6 GeV, which we will use to create and accelerate both electrons and positrons. Positrons will be created inside the linac at 4.46 GeV, will be accelerated up to 1.54 GeV at the linac, and will then be transferred to the designed damping ring. In this paper, we present the designed linac, damping ring, and the operational requirements of the 100 km booster.

Comment on "Collision monochromatization in e+e- colliders"

Bogomyagkov and Levichev [Phys. Rev. Accel. Beams 20, 051001 (2017), 10.1103/PhysRevAccelBeams.20.051001] have recently reported on monochromatization in collision schemes with crossing angle. From their results, in particular, it may seem that: (1) horizontal dispersion at the IP can provide monochromatization factor Λ ≫1 while retaining Piwinski angle ϕ >1 , (2) production rate in such a scheme for FCC-ee at 62.5 GeV can be larger than that in the nominal crab waist collision, and (3) strong rf focusing can be used for monochromatization purposes. We demonstrate here that the first two statements are not correct, and the last one is very doubtful.

The influence of housing on cognition and emotional regulation in mice presents a problem for the study of genetic and environmental risk factors for neuropsychiatric disorders: standard laboratory housing may result in low levels of cognitive function or altered levels of anxiety that leave little room for assessment of deleterious effects of experimental manipulations. The use of enriched environment (EE) may allow for the measurement of a wider range of performance in cognitive domains. Cognitive and behavioral effects of EE in male mice have not been widely reproduced, perhaps due to variability in the application of enrichment protocols, and the effects of EE in female mice have not been widely studied. We have developed an EE protocol using common laboratory equipment that, without a running wheel for exercise, results in significant cognitive and behavioral effects relative to standard laboratory housing conditions. We compared male and female wild-type C57BL/6J mice reared from weaning age in an EE to those reared in a standard environment (SE), using common measures of anxiety-like behavior, sensory gating, sociability, and spatial learning and memory. Sex was a significant factor in relevant elevated plus maze (EPM) measures, and bordered on significance in a social interaction (SI) assay. Effects of EE on anxiety-like behavior and sociability were indicative of a general increase in exploratory activity. In male and female mice, EE resulted in reduced prepulse inhibition (PPI) of the acoustic startle response, and enhanced spatial learning and use of spatially precise strategies in a Morris water maze task.

Physical interpretation of the J2 integral by identifying the associated crack translation

International Nuclear Information System (INIS)

Liu, Cong Hao; Chu, Seok Jae

2016-01-01

The physical interpretation of the J integral (i.e., J 1 integral) is clear. J 1 integral is the energy release rate associated with crack extension(i.e., translation of the crack in the x 1 direction). However, the physical interpretation of the J 2 integral remains unclear. In this study, different crack translations in the x 2 direction were selected and tested by calculating the energy release rates associated with the crack translations and comparing them with the theoretical value of the J 2 integral.

Partitioning of late gestation energy expenditure in ewes using indirect calorimetry and a linear regression approach

DEFF Research Database (Denmark)

Kiani, Alishir; Chwalibog, André; Nielsen, Mette O

2007-01-01

Late gestation energy expenditure (EE(gest)) originates from energy expenditure (EE) of development of conceptus (EE(conceptus)) and EE of homeorhetic adaptation of metabolism (EE(homeorhetic)). Even though EE(gest) is relatively easy to quantify, its partitioning is problematic. In the present...... study metabolizable energy (ME) intake ranges for twin-bearing ewes were 220-440, 350- 700, 350-900 kJ per metabolic body weight (W0.75) at week seven, five, two pre-partum respectively. Indirect calorimetry and a linear regression approach were used to quantify EE(gest) and then partition to EE......(conceptus) and EE(homeorhetic). Energy expenditure of basal metabolism of the non-gravid tissues (EE(bmng)), derived from the intercept of the linear regression equation of retained energy [kJ/W0.75] and ME intake [kJ/W(0.75)], was 298 [kJ/ W0.75]. Values of the intercepts of the regression equations at week seven...

Chronic intermittent ethanol inhalation increases ethanol self-administration in both C57BL/6J and DBA/2J mice.

Science.gov (United States)

McCool, Brian A; Chappell, Ann M

2015-03-01

Inbred mouse strains provide significant opportunities to understand the genetic mechanisms controlling ethanol-directed behaviors and neurobiology. They have been specifically employed to understand cellular mechanisms contributing to ethanol consumption, acute intoxication, and sensitivities to chronic effects. However, limited ethanol consumption by some strains has restricted our understanding of clinically relevant endpoints such as dependence-related ethanol intake. Previous work with a novel tastant-substitution procedure using monosodium glutamate (MSG or umami flavor) has shown that the procedure greatly enhances ethanol consumption by mouse strains that express limited drinking phenotypes using other methods. In the current study, we employ this MSG-substitution procedure to examine how ethanol dependence, induced with passive vapor inhalation, modifies ethanol drinking in C57BL/6J and DBA/2J mice. These strains represent 'high' and 'low' drinking phenotypes, respectively. We found that the MSG substitution greatly facilitates ethanol drinking in both strains, and likewise, ethanol dependence increased ethanol consumption regardless of strain. However, DBA/2J mice exhibited greater sensitivity dependence-enhanced drinking, as represented by consumption behaviors directed at lower ethanol concentrations and relative to baseline intake levels. DBA/2J mice also exhibited significant withdrawal-associated anxiety-like behavior while C57BL/6J mice did not. These findings suggest that the MSG-substitution procedure can be employed to examine dependence-enhanced ethanol consumption across a range of drinking phenotypes, and that C57BL/6J and DBA/2J mice may represent unique neurobehavioral pathways for developing dependence-enhanced ethanol consumption.

The cross section for back-to-back hadron pair production in e+e- annihilation provides access to the dihadron fragmentation functions (DiFF) needed to extract nucleon parton distribution functions from the semi-inclusive deep inelastic scattering (SIDIS) experiments with two detected final state hadrons. Particular attention is given to the so-called interference DiFF (IFF), which makes it possible to extract the transversity parton distribution of the nucleon in the collinear framework. However, previously unnoticed discrepancies were recently highlighted between the definitions of the IFFs appearing in the collinear kinematics when reconstructed from DiFFs entering the unintegrated fully differential cross sections of SIDIS and e+e- annihilation processes. In this work, to clarify this problem we re-derive the fully differential cross section for e+e- annihilation at the leading-twist approximation. We find a mistake in the definition of the kinematics in the original expression that systematically affects a subset of terms and that leads to two significant consequences. First, the discrepancy between the IFF definitions in the cross sections for SIDIS and e+e- annihilation is resolved. Second, the previously derived azimuthal asymmetry for accessing the helicity dependent DiFF G1⊥ in e+e- annihilation vanishes, which explains the nonobservation of this asymmetry in the recent experimental searches by the BELLE collaboration. We discuss the recently proposed alternative option to extract G1⊥.

anti ee annihilation into hadrons from dual unitarisation

International Nuclear Information System (INIS)

Hong-mo, C.

1976-09-01

By grafting to the dual unitarisation scheme for hadron reactions a quark-current coupling suggested by the parton model, a model is obtained for anti ee annihilations in which the conversion of quarks into final hadrons is specific. As a first application, the correction to the value of R given by the parton model is estimated. (author)

Verticalization of behavior elicited by dopaminergic mobilization is qualitatively different between C57BL/6J and DBA/2J mice.

Science.gov (United States)

Tirelli, E; Witkin, J M

1994-10-01

Behavioral effects of dopaminergic stimulation were evaluated in C57BL/6J mice and compared to the effects occurring in DBA/2J mice, an inbred strain with reduced densities of striatal dopamine receptors. Effects of apomorphine (0.5-64 mg/kg) alone and in combination with cocaine (30 mg/kg) were assessed using a time-sampling technique that classified climbing and leaning in separate categories. Locomotion was also assessed in a separate experiment. Climbing occurred in DBA/2J mice only at doses of apomorphine that were 16 times higher than the smallest effective dose in C57BL/6J mice; nevertheless, relative to baseline values, effects were fairly comparable. By contrast, whereas DBA/2J mice showed dose-dependent leaning under apomorphine, C57BL/6J mice exhibited little leaning even at doses not producing climbing, and only after the highest apomorphine dose was leaning significantly increased. Apomorphine was equipotent in inducing gnawing across strains, although somewhat less efficacious in DBA/2J mice. When given alone, cocaine produced significant climbing, but not leaning or gnawing, in either strain. Whereas cocaine potentiated apomorphine-induced climbing and gnawing in both strains, apomorphine-induced leaning was not consistently changed by cocaine in either strain. These effects were not indirectly due to hyperkinesia, since neither apomorphine alone nor apomorphine and cocaine in combination was stimulant; apomorphine alone reduced locomotor activity and attenuated cocaine-induced hyperkinesia. The present data do not support a unitary, purely quantitative, account of insensitivity to dopaminergic stimulation based upon low densities of striatal dopamine receptors in DBA/2J mice. Rather, this constellation of results is suggestive of qualitative interstrain dissimilarities in dopaminergic responsiveness that could reflect organizational differences in receptor populations.

Measurement of total hadronic cross section σ(e+e-→hadrons) in the continuum at the c.m. energy W=9.39 GeV and determination of Γee of the Υ(1S) and Υ(2S) resonances

International Nuclear Information System (INIS)

Jakubowski, Z.

1990-01-01

This work is based on a study of e + e - collisions in the energy region of Υ(1S) and Υ(2S) resonances. Using the data taken by the Crystal Ball Detector in the continuum below Υ(1S) we have determined the value of R, the ratio of the hadronic cross section to the Born cross section of μ pair production, at c.m. energy W = 9.39 GeV to be R = 3.48±0.04±0.14. This is the most precise measurement of R below the Υ(1S) threshold. Resonance scan data were used to determine the leptonic partial widths Γ ee of Υ(1S) and Υ(2S). We find Γ ee (Υ(1S))=(1.34±0.03±0.06) keV, Γ ee (Υ(2S))=(0.56±0.03±0.02) keV. The method of obtaining Γ ee from the measured excitation curve is not unique. Our results are ∝10% higher than those already published mainly because we used an internally consistent treatment of the radiative corrections. We discuss the effect of applying different theoretical prescriptions for the radiative corrections on Γ ee . Both results presented here require the knowledge of the absolute cross sections to a high precision. Uncertainties in the corrections to the cross section due to detector efficiency constitute the main source of the systematic error. To minimize these uncertainties substantial modifications of the detector simulation program GHEISHA were necessary to obtain a satisfactory description of the data. The modifications may be of importance for other calorimetric experiments. (orig.)

Universal factorization of 3n-j(j > 2) symbols of the first and second kinds for SU(2) group and their direct and exact calculation and tabulation

International Nuclear Information System (INIS)

Wei Liqiang; Dalgarno, Alexander

2004-01-01

We show that general 3n-j(n > 2) symbols of the first and second kinds for the group SU(2) can be reformulated in terms of binomial coefficients. The proof is based on the graphical technique established by Yutsis et al and through a definition of a reduced 6-j symbol. The resulting 3n-j symbols thereby take a combinatorial form which is simply the product of two factors. The one is an integer or polynomial which is the single sum over the products of reduced 6-j symbols. They are in the form of summing over the products of binomial coefficients. The other is a multiplication of all the triangle relations appearing in the symbols, which can also be rewritten using binomial coefficients. The new formulation indicates that the intrinsic structure for the general recoupling coefficients is much nicer and simpler, which might serve as a bridge for study with other fields. Along with our newly developed algorithms, this also provides a basis for a direct, exact and efficient calculation or tabulation of all the 3n-j symbols of the SU(2) group for all the range of quantum angular momentum arguments. As an illustration, we present the results for the 12-j symbols of the first kind

Space-charge-mediated anomalous ferroelectric switching in P(VDF-TrEE) polymer films

KAUST Repository

Hu, Weijin

2014-11-12

We report on the switching dynamics of P(VDF-TrEE) copolymer devices and the realization of additional substable ferroelectric states via modulation of the coupling between polarizations and space charges. The space-charge-limited current is revealed to be the dominant leakage mechanism in such organic ferroelectric devices, and electrostatic interactions due to space charges lead to the emergence of anomalous ferroelectric loops. The reliable control of ferroelectric switching in P(VDF-TrEE) copolymers opens doors toward engineering advanced organic memories with tailored switching characteristics.

A data sample corresponding to 1.23 million hadronic Z decays collected by the ALEPH detector at LEP has been searched for signals of the production of a non-minimal CP-even Higgs boson h in the reaction e+e- → hZ∗. The h decay modes considered were: those of the minimal standard model Higgs boson, with modified branching ratios; decays into a pair of CP-odd Higgs bosons A; and decays into invisible final states. Only one event was found, a very acoplanar e +e - pair which could originate from the standard model background process e+e- → e+e-v v¯. Upper limits for the cross-section of the reaction e+e- → hZ∗ have been derived as a function of mh, the mass of the Higgs boson h. In the case of invisible decays, the 95% CL lower limit on mh is 65 GeV/ c2 for a production cross-section equal to that of a minimal standard model Higgs boson. When combined with previous ALEPH results on the reaction e +e - → hA, these cross-section upper limits exclude a domain in the ( mhmA) plane of the MSSM such that if invisible h and A decays can be neglected, 95% CL lower limits of 44 and 21 GeV/ c2 result for mh and mA, respectively, independent of the other parameters of the model.

Sweet and bitter taste of ethanol in C57BL/6J and DBA2/J mouse strains.

Blizard, David A

2007-01-01

Studies of inbred strains of rats and mice have suggested a positive association between strain variations in sweet taste and ethanol intake. However, strain associations by themselves are insufficient to support a functional link between taste and ethanol intake. We used conditioned taste aversion (CTA) to explore the sweet and bitter taste of ethanol and ability to detect sucrose, quinine and ethanol in C57BL/6J (B6) and DBA/2J (D2) mouse strains that are frequently used in alcohol research. The present study showed that C57BL/6J mice generalized taste aversions from sucrose and quinine solutions to 10% ethanol and, reciprocally, aversions to 10% ethanol generalized to each of these solutions presented separately. Only conditioned aversions to quinine generalized to ethanol in the DBA/2J strain but an aversion conditioned to ethanol did not generalize reciprocally to quinine. Thus, considering these two gustatory qualities, 10% ethanol tastes both sweet and bitter to B6 mice but only bitter to D2. Both strains were able to generalize taste aversions across different concentrations of the same compound. B6 were able to detect lower concentrations of quinine than D2 but both strains were able to detect sucrose and (in contrast to previous findings) ethanol at similar concentrations. The strain-dependent gustatory profiles for ethanol may make an important contribution to the understanding of the undoubtedly complex mechanisms influencing high ethanol preference of B6 and pronounced ethanol avoidance of D2 mice.

BPH/2J mice are recognized as a neurogenic model of hypertension primarily based on overactivity of the sympathetic nervous system and greater neuronal activity in key autonomic cardiovascular regulatory brain regions. The medial amygdala (MeAm) is a forebrain region that integrates the autonomic response to stress and is the only region found to have greater Fos during the night and daytime in BPH/2J compared with BPN/3J mice. To determine the contribution of the MeAm to hypertension, the effect of neuronal ablation on blood pressure (BP) was assessed in BPH/2J (n=7) and normotensive BPN/3J mice (n=7). Mice were preimplanted with radiotelemetry devices to measure 24-hour BP and cardiovascular responses to stress, before and 1 to 3 weeks after bilateral lesions of the MeAm. Baseline BP was 121±4 mm Hg in BPH/2J and 101±2 mm Hg in BPN/3J mice (PstrainBPH/2J mice (PlesionBPH/2J mice was similar during both day and night, suggesting that the MeAm has tonic effects on BP, but the pressor response to stress was maintained in both strains. Midfrequency BP power was attenuated in both strains (PlesionBPH/2J mice (PlesionBPH/2J mice, which is independent of its role in stress reactivity or circadian BP influences.

A detailed characterisation of the luminescence recorded for the 6p 1P1-6s 1S0 transition of atomic barium isolated in annealed solid xenon has been undertaken using two-dimensional excitation-emission (2D-EE) spectroscopy. In the excitation spectra extracted from the 2D-EE scans, two dominant thermally stable sites were identified, consisting of a classic, three-fold split Jahn-Teller band, labeled the blue site, and an unusual asymmetric 2 + 1 split band, the violet site. A much weaker band has also been identified, whose emission is strongly overlapped by the violet site. The temperature dependence of the luminescence for these sites was monitored revealing that the blue site has a non-radiative channel competing effectively with the fluorescence even at 9.8 K. By contrast, the fluorescence decay time of the violet site was recorded to be 4.3 ns and independent of temperature up to 24 K. The nature of the dominant thermally stable trapping sites was investigated theoretically with Diatomics-in-Molecule (DIM) molecular dynamics simulations. The DIM model was parameterized with ab initio multi-reference configuration interaction calculations for the lowest energy excited states of the BaṡXe pair. The simulated absorption spectra are compared with the experimental results obtained from site-resolved excitation spectroscopy. The simulations allow us to assign the experimental blue feature spectrum to a tetra-vacancy trapping site in the bulk xenon fcc crystal—a site often observed when trapping other metal atoms in rare gas matrices. By contrast, the violet site is assigned to a specific 5-atom vacancy trapping site located at a grain boundary.

A search for neutral Higgs bosons has been performed with the OPAL detector at LEP, using approximately 170 pb-1 of e+e- collision data collected at sqrt(s)~189GeV. Searches have been performed for the Standard Model (SM) process e+e- to H0Z0 and the MSSM processes e+e- to H0Z0, A0h0. The searches are sensitive to the b b-bar and tau antitau decay modes of the Higgs bosons, and also to the MSSM decay mode h0 to A0A0. OPAL search results at lower centre-of-mass energies have been incorporated in the limits we set, which are valid at the 95% confidence level. For the SM Higgs boson, we obtain a lower mass bound of 91.0 GeV. In the MSSM, our limits are mh>74.8GeV and mA>76.5GeV, assuming tan(beta)>1, that the mixing of the scalar top quarks is either zero or maximal, and that the soft SUSY-breaking masses are 1 TeV. For the case of zero scalar top mixing, we exclude values of tan(beta) between 0.72 and 2.19.

Full Text Available En las carreras de pregrado en Educación de la Universidad del Magdalena, la mayor parte de los docentes adoptan un modelo de enseñanza tradicional, pese a que las TIC ofrecen la posibilidades de interacción docente - estudiantes, no la utilizan de manera asertiva en sus clases, debido a que consideran que sólo resultan útiles en la educación a distancia. En los últimos tres años, un grupo reducido de docentes han comenzado a incorporar, de manera tímida, la plataforma WebCT como escenarios complementarios a la clase presencial, pero no se han realizado investigaciones que recojan las percepciones de los actores, que demuestren la efectividad de la utilización combinada de actividades colaborativas presenciales con las actividades apoyadas en la plataforma virtual. El propósito de la investigación fue analizar la efectividad de la plataforma WebCT en el desarrollo de un curso de formación disciplinar impartido de manera tradicional presencial complementado con enseñanza virtual, apoyada en los aportes de Vygotsky, Ausubel, Pozo, Coll, Marqués, Sangrá, entre otros, realizada de acuerdo con el paradigma cualitativo, con un enfoque descriptivo y con un diseño correspondiente a un Estudio de caso, en el cual se utilizó como técnicas el grupo focal y dos encuestas que permitieron apreciar la opinión de los estudiantes acerca del uso de las TIC y uso de la plataforma WebCT, así como la interacción en las actividades desarrolladas durante el curso en la plataforma virtual. Para ello se contó con la participación de 70 estudiantes de Licenciatura en Informática en el primer semestre académico de 2010. Los resultados indican que en el modelo didáctico híbrido se combinan la responsabilidad, rapidez y calidad de respuesta del docente con la participación fluida del estudiante en la realización de actividades y entregas de trabajos, por los aportes al grupo a través de los foros y del Chat, así como la motivación generada

Background: Incomplete stent apposition (ISA) is related to stent thrombosis, which is a serious adverse event. We aim to assess the time-course of ISA after 2nd generation everolimus-eluting stent (EES) implantation. Methods: In HEAL-EES study, we enrolled 36 patients who underwent percutaneous coronary intervention (PCI) with EES. OCT imaging was performed at baseline and follow-up. Patients were randomized 1:1:1 into 3 groups according to the time in which follow-up was performed: group A (6-month), group B (9-month), and group C (12-month). In this subanalysis, patients who had ISA segments at baseline and/or follow-up OCT were analyzed. Result: At baseline, among 41 lesions in 36 patients, 20 lesions in 18 patients had ISA segments and were analyzed. At baseline, there were 3.0% ISA struts in group A (n = 8), 2.8% in group B (n = 4), and 4.5% in group C (n = 8). At follow-up, ISA struts were present in 0.09%, 0.16% and 0.64%; respectively in groups A, B, and C. At follow-up, there was a significant decrease in the frequency of ISA: group A 3.0% vs. 0.09% (p < 0.001), group B 2.8% vs. 0.16% (p < 0.001), and group C 4.5% vs. 0.64% (p < 0.001). In group A, there was one late acquired ISA at follow-up. Conclusions: In patients undergoing 2nd generation EES implantation, area of acute ISA assessed by OCT, was almost resolved at 6-month follow-up. - Highlights: • Time-course of incomplete stent apposition of everolimus-eluting stent was assessed. • Serial optical coherence tomography images at baseline and follow-up were evaluated. • Acute incomplete stent apposition was almost resolved as early as at 6 months.

Elastic and proton dissociative J/ψ photoproduction at low Wγp with the H1 detector at HERA

International Nuclear Information System (INIS)

Huber, Florian

2013-02-01

Elastic and proton dissociative photoproduction of J/ψ mesons is measured with the H1 detector at the HERA electron proton collider in the photon virtuality phase space of Q 2 2 . Two data sets are analysed, one measured with a nominal proton beam energy of 920 GeV, corresponding to an ep centre of mass energy of 318 GeV and one recorded with a reduced beam energy of 460 GeV, corresponding to an ep centre of mass energy of 225 GeV. The combination of the two data sets allow to perform the J/ψ measurement with central tracks in an extended kinematic phase space in a photon proton centre of mass energy range of 20 GeV γp -1 and 10.8 pb -1 , respectively, corresponding to more than two times the statistics used in previous H1 analyses. Due to an online selection purely based on tracks both leptonic decay channels J/ψ→ee and J/ψ→μμ are available for the analysis. Elastic (γp→ J/ψp) and proton dissociative (γp→ J/ψY) differential γp cross sections are determined in a simultaneous measurement as function of the squared momentum transfer at the proton vertex t and as function of W γp by means of an unfolding procedure, taking not only all bin correlations into account, but also the correlation between the elastic and proton dissociative process. The obtained elastic and proton dissociative differential cross sections are analysed in a simultaneous fit, taking the full statistical covariance matrices and systematic uncertainty sources into account.

Objective To evaluate the value of free-run electromyography (f-EMG) monitoring of extraocular cranial nerves (EOCN) III, IV, and VI during expanded endonasal surgery (EES) of the skull base in reducing iatrogenic cranial nerve (CN) deficits. Design We retrospectively identified 200 patients out of 990 who had at least one EOCN monitored during EES. We further separated patients into groups according to the specific CN monitored. In each CN group, we classified patients who had significant (SG) f-EMG activity as Group I and those who did not as Group II. Results A total of 696 EOCNs were monitored. The number of muscles supplied by EOCNs that had SG f-EMG activity was 88, including CN III = 46, CN IV = 21, and CN VI = 21. There were two deficits involving CN VI in patients who had SG f-EMG activity during surgery. There were 14 deficits observed, including CN III = 3, CN IV = 2, and CN VI = 9 in patients who did not have SG f-EMG activity during surgery. Conclusions f-EMG monitoring of EOCN during EES can be useful in identifying the location of the nerve. It seems to have limited value in predicting postoperative neurological deficits. Future studies to evaluate the EMG of EOCN during EES need to be done with both f-EMG and triggered EMG.

Evidence is presented for the decay $B_c+\\rightarrow J/\\psi 3\\pi^+2\\pi^-$ using proton-proton collision data, corresponding to an integrated luminosity of 3fb$^{-1}$, collected with the LHCb detector. A signal yield of $32\\pm8$ decays is found with a significance of 4.5 standard deviations. The ratio of the branching fraction of the $B_c^+\\rightarrow J/\\psi 3\\pi^+ 2\\pi^-$ decay to that of the $B_c^+ \\rightarrow J/\\psi \\pi^+$ decay is measured to be $$ \\frac{Br (B_c^+ \\rightarrow J/\\psi 3\\pi^+2\\pi^)}{Br (B_c^+ \\rightarrow J/\\psi \\pi^+)} = 1.74\\pm0.44\\pm0.24, $$ where the first uncertainty is statistical and the second is systematic.

Photonic events with large missing energy have been observed in e+e- collisions at a centre-of-mass energy of 189GeV using the OPAL detector at LEP. Results are presented for event topologies consistent with a single photon or with an acoplanar photon pair. Cross-section measurements are performed within the kinematic acceptance of each selection, and the number of light neutrino species is measured. Cross-section results are compared with the expectations from the Standard Model process e+e- to nu nubar + photon(s). No evidence is observed for new physics contributions to these final states. Upper limits are derived on sigma(e+e- to XY).BR(X to Y gamma) and sigma(e+e- to XX).BR**2(X to Y gamma) for the case of stable and invisible Y. These limits apply to single and pair production of excited neutrinos (X=nu*, Y = nu), to neutralino production (X=neutralino_2, Y=neutralino_1) and to supersymmetric models in which X = neutralino_1 and Y = light gravitino. The case of macroscopic decay lengths of particle X is...

A measurement of the cross-section for Z-boson production in the forward region of pp collisions at 8TeV centre-of-mass energy is presented. The measurement is based on a sample of $\\rm Z\\rightarrow e^+e^-$ decays reconstructed using the LHCb detector, corresponding to an integrated luminosity of 2.0fb$^{-1}$. The acceptance is defined by the requirements $2.020$GeV for the pseudorapidities and transverse momenta of the leptons. Their invariant mass is required to lie in the range 60--120GeV. The cross-section is determined to be $\\sigma({\\rm pp\\to Z\\to e^+e^-})=93.81\\pm0.41({\\rm stat})\\pm1.48({\\rm syst})\\pm1.14({\\rm lumi})\\;{\\rm pb}\\,,$ where the first uncertainty is statistical and the second reflects all systematic effects apart from that arising from the luminosity, which is given as the third uncertainty. Differential cross-sections are presented as functions of the Z-boson rapidity and of the angular variable $\\phi^*$, which is related to the Z-boson transverse momentum.

In this Letter the decay $\\overline{B}^0_s \\to J/\\psi K^+ K^-$ is investigated. Although the $J/\\psi \\phi$ channel is well known, final states at higher $K^+K^-$ masses have not previously been studied. In the $K^+K^-$ mass spectrum we observe a significant signal in the $f'_2(1525)$ region as well as a non-resonant component. The ratio of the rate in a $K^+K^-$ mass window of $\\pm 125$ MeV around the $f'_2$ relative to that in the $J/\\psi \\phi$ decay, where $\\phi \\to K^+K^-$, is $R=(19.4 \\pm 1.8 \\pm 1.0)$%. Our sample consists of $0.16$ fb$^{-1}$ collected with the LHCb detector using 7 TeV $pp$ collisions.

Alignment-free genome and metagenome comparisons are increasingly important with the development of next generation sequencing (NGS) technologies. Recently developed state-of-the-art k-mer based alignment-free dissimilarity measures including CVTree, $d_2^*$ and $d_2^S$ are more computationally expensive than measures based solely on the k-mer frequencies. Here, we report a standalone software, aCcelerated Alignment-FrEe sequence analysis (CAFE), for efficient calculation of 28 alignment-free dissimilarity measures. CAFE allows for both assembled genome sequences and unassembled NGS shotgun reads as input, and wraps the output in a standard PHYLIP format. In downstream analyses, CAFE can also be used to visualize the pairwise dissimilarity measures, including dendrograms, heatmap, principal coordinate analysis and network display. CAFE serves as a general k-mer based alignment-free analysis platform for studying the relationships among genomes and metagenomes, and is freely available at https://github.com/younglululu/CAFE. © The Author(s) 2017.

The search for s-channel production of light neutral particles coupled to e + e- has been extended by more than 3 orders of magnitude in lifetime beyond the region which is accessible to elastic e + e- scattering. The whole mass range 1500 approx-lt M X 0 approx-lt 1860 keV/c 2 suggested by the observation of anomalous e + e- pairs in heavy-ion collisions has been investigated. These measurements find no evidence for e + e- states within lifetime ranges (90% C.L.) of 1.4x10 -12 approx-lt τ approx-lt 4x10 -10 sec (J=0) and 1.4x10 -12 approx-lt τ approx-lt 6x10 -10 sec (J=1), assuming that the state does not break up by interacting within the target

Summer composition and distribution of the jellyfish (Cnidaria: Medusozoa in the shelf area off the central Mexican Pacific Composición y distribución de las medusas (Cnidaria: Medusozoa en la plataforma continental central del Pacifico mexicano

Full Text Available The composition, distribution, and abundance of the jellyfish community of a shelf area of the Mexican tropical Pacific were surveyed during August 1988. Zooplankton samples were collected along transects on the outer and inner sectors of the continental shelf to determine the structure of the jellyfish community and its variation in this area during the rainy season. A total of 23 species were recorded, with Aglaura hemistoma, Solmundella bitentaculata, Liriope tetraphylla, Pelagia noctiluca, and Rhopalonema velatum being the most abundant. The total abundance of medusae and of the most abundant species was statistically independent of depth and distance to the coast. Hence, the total jellyfish abundance of the most abundant species, and Shannon's Diversity index had a uniform distribution in both the inner and the outer shelf; furthermore, neritic-oceanic forms and oceanic species occurred indistinctly over the entire continental shelf. On the outer shelf A. hemistoma and S. bitentaculata were most abundant; the former species, together with L. tetraphylla, weakly characterized the inner shelf jellyfish community. The narrowness of the shelf, the wide distribution of the most abundant forms, and the possible effect of local advective processes from the oceanic zone masked a definite gradient across the shelf. Three species have not been recorded previously in the Mexican Pacific: Amphinema dinema (Péron and Lesueur, 1810, Sarsia coccometra Bigelow, 1909, and Clytia mccradyi (Brooks, 1888. The finding of A. dinema is the first in the Eastern Pacific.Se estudió la composición, distribución y abundancia de la comunidad de medusas de la plataforma continental en el Pacífico mexicano durante agosto 1988.

We present a phenomenological study of scalar leptoquarks, which are new particles predicted by composite models, using, in particular, the Abbott-Farhi model. We have calculated the production of leptoquarks in e{gamma} collisions within ee colliders, utilizing the laser back-scattering process to create the incident beam of photons. We are able to conclude e{gamma} collisions provide a good way to find scalar leptoquarks. (author) 29 refs., 30 figs., 1 tab.

Comparison of experimental and theoretical integral cross sections for D+H2(v=1, j=1)→HD(v'=1, j')+H

International Nuclear Information System (INIS)

Kliner, D.A.V.; Adelman, D.E.; Zare, R.N.

1991-01-01

We have measured the nascent HD(v'=1, j') product rotational distribution from the reaction D+H 2 (v, j) in which the H 2 reagent was either thermal (v=0, j) or prepared in the level (v=1, j=1) by stimulated Raman pumping. Translationally hot D atoms were obtained by uv laser photolysis of DBr or DI. Photolysis of DBr generated D atoms with center-of-mass collision energies (E rel ) of 1.04 and 0.82 eV, which corresponded to the production of ground state Br and spin--orbit-excited Br*, respectively. The E rel values for DI photolysis were 1.38 and 0.92 eV. Quantum-state-specific detection of HD was accomplished via (2+1) resonance-enhanced multiphoton ionization and time-of-flight mass spectrometry. Vibrational excitation of the H 2 reagent results in substantial rotational excitation of the HD(v'=1) product and increases the reaction rate into v'=1 by about a factor of 4. Although the quantum-mechanical calculation of Blais et al. [Chem. Phys. Lett. 166, 11 (1990)] for the D+H 2 (v=1, j=1)→HD(v'=1, j')+H product rotational distribution at E rel =1.02 eV is in qualitative agreement with experiment, it does not quantitatively agree with the measured distribution. Specifically, the calculated distribution is too hot by 2--3 rotational quanta, and the predicted enhancement in the v'=1 rate with reagent vibrational excitation is too large by 67%±9

We have discovered that the extremely red, low-gravity L7 dwarf 2MASS J11193254-1137466 is a 0.″14 (3.6 au) binary using Keck laser guide star adaptive optics imaging. 2MASS J11193254-1137466 has previously been identified as a likely member of the TW Hydrae Association (TWA). Using our updated photometric distance and proper motion, a kinematic analysis based on the BANYAN II model gives an 82% probability of TWA membership. At TWA’s 10 ± 3 Myr age and using hot-start evolutionary models, 2MASS J11193254-1137466AB is a pair of {3.7}-0.9+1.2 {M}{Jup} brown dwarfs, making it the lowest-mass binary discovered to date. We estimate an orbital period of {90}-50+80 years. One component is marginally brighter in K band but fainter in J band, making this a probable flux-reversal binary, the first discovered with such a young age. We also imaged the spectrally similar TWA L7 dwarf WISEA J114724.10-204021.3 with Keck and found no sign of binarity. Our evolutionary model-derived {T}{eff} estimate for WISEA J114724.10-204021.3 is ≈230 K higher than for 2MASS J11193254-1137466AB, at odds with the spectral similarity of the two objects. This discrepancy suggests that WISEA J114724.10-204021.3 may actually be a tight binary with masses and temperatures very similar to 2MASS J11193254-1137466AB, or further supporting the idea that near-infrared spectra of young ultracool dwarfs are shaped by factors other than temperature and gravity. 2MASS J11193254-1137466AB will be an essential benchmark for testing evolutionary and atmospheric models in the young planetary-mass regime.

2017-01-01

The report describes a method for a fast and precise beam energy measurement in the beam energy range 0.5-2 GeV and its application at various e+e- colliders. Low-energy laser photons interact head-on with the electron or positron beam and produce Compton backscattered photons whose energy is precisely measured by HPGe detector. The method allows measuring the beam energy with relative accuracy of ∼2-5.10-5. The method was successfully applied at VEPP-4M, VEPP-3, VEPP-2000 (BINP, Russia) and BEPC-II (IHEP, China).

Search for supersymmetric particles in e+e- collisions at centre-of-mass energies of 130 and 136 GeV. Searches for supersymmetric particles produced in e+e- collisions at centre-of-mass energies of 130 and 136 GeV have been performed in a data sample of 5.7 pb-1 collected in the autumn of 1995 by the ALEPH detector at LEP. No candidate events were found, allowing limits to be set on the masses and production cross-sections of scalar leptons, scalar tops charginos and neutralinos. The domains previously excluded at LEP1 are substantially extended. For instance, masses of gaugino-like charginos smaller than 67.8 GeV/c2 are excluded at the 95% C.L. for scalar neutrino masses larger than 200 GeV/c2.

Ground-state phases of the spin-1 J1-J2 Heisenberg antiferromagnet on the honeycomb lattice

2016-06-01

We study the zero-temperature quantum phase diagram of a spin-1 Heisenberg antiferromagnet on the honeycomb lattice with both nearest-neighbor exchange coupling J1>0 and frustrating next-nearest-neighbor coupling J2≡κ J1>0 , using the coupled cluster method implemented to high orders of approximation, and based on model states with different forms of classical magnetic order. For each we calculate directly in the bulk thermodynamic limit both ground-state low-energy parameters (including the energy per spin, magnetic order parameter, spin stiffness coefficient, and zero-field uniform transverse magnetic susceptibility) and their generalized susceptibilities to various forms of valence-bond crystalline (VBC) order, as well as the energy gap to the lowest-lying spin-triplet excitation. In the range 0 κc 2=0.340 (5 ) . Two different paramagnetic phases are found to exist in the intermediate region. Over the range κc1<κ<κci=0.305 (5 ) we find a gapless phase with no discernible magnetic order, which is a strong candidate for being a quantum spin liquid, while over the range κci<κ <κc 2 we find a gapped phase, which is most likely a lattice nematic with staggered dimer VBC order that breaks the lattice rotational symmetry.

Highlights: • Transport ac loss in a thin strip with power-law E(J) is systematically computed. • The scaled results can be accurately used for strips with any critical current and frequency. • Experiments may be unambiguously compared with modeling results at a critical frequency. - Abstract: Transport ac losses of a rectangular thin strip obeying relation E/E c =(J/J c ) n with a fixed critical current I c and n=5,10,20,30, and 40 are accurately computed at a fixed frequency f as functions of the current amplitude I m . The results may be interpolated and scaled to those at any values of I c ,f, and 5⩽n⩽40. Normalized in the same way as that in Norris’ analytical formula derived from the critical-state model and converting f to a critical frequency f c , the modeling results may be better compared with the Norris formula and experimental data. A complete set of calculated modeling data are given with necessary formulas to be easily used by experimentalists in any particular case

Mapas cotidais e elipses de correntes da componente M2 foram obtidos, sendo esta componente preponderante na circulação local. Elevações e correntes sazonais médias são, em geral, muito menores que as astronômicas, permitindo o uso apenas de forçantes de maré em previsões hidrodinámicas. As simulações do modelo foram satisfatórias na plataforma e menos precisas nas baías e áreas internas rasas, onde atrasos de fase significativos são observados, devido a efeitos de menor escala que a adotada pelo modelo.A linear three-dimensional hydrodynamical numerical model, Heaps type, was implemented to the continental shelf of Maranhão State, aiming the simulation of the circulation generated by astronomical and meteorological effects in that area.

Beams 20, 051001 (2017PRABCJ2469-988810.1103/PhysRevAccelBeams.20.051001] have recently reported on monochromatization in collision schemes with crossing angle. From their results, in particular, it may seem that: (1 horizontal dispersion at the IP can provide monochromatization factor Λ≫1 while retaining Piwinski angle ϕ>1, (2 production rate in such a scheme for FCC-ee at 62.5 GeV can be larger than that in the nominal crab waist collision, and (3 strong rf focusing can be used for monochromatization purposes.

VizieR Online Data Catalog: W1J00 and W2J00 Transit Circle Catalogs (Rafferty+, 2016)

Rafferty, T. J.; Holdenried, E. R.; Urban, S. E.

2016-06-01

The W1J00, named because it was the first (of two) Washington transit circle catalog to be referred to the Equinox of J2000.0, is the result of observations made with the Six-inch Transit Circle in Washington, D.C., between September 1977 and July 1982. The observing program was structured to be absolute, in the sense that the positions were not explicitly relying on any previous observations. The absolute positions were defined with respect to an internally consistent frame that was unique to the particular instrument. Following the reductions, comparisons with stars from the Hipparcos Catalogue (European Space Agency 1997) revealed unaccounted for systematic differences on the level of 100-200mas. It was decided, therefore, to include data on both the absolute positions reduced in way common to many past Washington transit circle catalogs, as well as the positions differentially adjusted to the system of the Hipparcos Catalog. The W1J00 contains mean positions of 7267 stars and 4383 observations of solar system objects. The majority of the stars fall into two categories; those from the Fifth Fundamental Catalog (FK5; Fricke et al 1988), and those from the Catalog Of 3539 Zodiacal Stars For The Equinox 1950.0 (Robertson 1940). The solar system objects include the Sun, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, eight minor planets (Eunomia, Flora, Hebe, Iris, Juno, Metis, Pallas, and Vesta), and the dwarf planet Ceres. Characteristics of the W1J00 catalog: Category Range Average ------------------------------------------------------------- Magnitudes -1.6 to 10.4 7.18 RA standard errors of the mean 15 to 460 mas 98 mas Dec standard errors of the mean 10 to 400 mas 107 mas RA Number of observations / star 3 to 187 10 Dec Number of observations / star 2 to 179 10 Declination coverage -39 to +90 degrees ------------------------------------------------------------- Details of the W1J00 can be found in Rafferty, Holdenried, and Urban (2016, Publ.

A simple FORTRAN program for the exaxt computation of 3-j and 6-j symbols has been written for the VAX with VMS version v5.1 in our university's computing center. It goes beyond and contains all of the 3-j and 6-j symbols evaluated in the book by M. Rotenberg, R. Bivins, N. Metropolis and J.K. Wooten Jr. The 3-j symbols up to (30/m 1 30/m 2 30/m 3 ) and 6-j symbols up to {20/20 20/20 20/20} can be computed exactly by this program. Approximate values for larger j's up to (200/m 1 200/m 2 200/m 3 ) and {200/200 200/200 200/220} can also be computed by this program. (orig.)

Elastic and proton dissociative J/{psi} photoproduction at low W{sub {gamma}p} with the H1 detector at HERA

Energy Technology Data Exchange (ETDEWEB)

Huber, Florian

2013-02-15

Elastic and proton dissociative photoproduction of J/{psi} mesons is measured with the H1 detector at the HERA electron proton collider in the photon virtuality phase space of Q{sup 2}2.5 GeV{sup 2}. Two data sets are analysed, one measured with a nominal proton beam energy of 920 GeV, corresponding to an ep centre of mass energy of 318 GeV and one recorded with a reduced beam energy of 460 GeV, corresponding to an ep centre of mass energy of 225 GeV. The combination of the two data sets allow to perform the J/{psi} measurement with central tracks in an extended kinematic phase space in a photon proton centre of mass energy range of 20 GeVJ/{psi}{yields}ee and J/{psi}{yields}{mu}{mu} are available for the analysis. Elastic ({gamma}p{yields} J/{psi}p) and proton dissociative ({gamma}p{yields} J/{psi}Y) differential {gamma}p cross sections are determined in a simultaneous measurement as function of the squared momentum transfer at the proton vertex t and as function of W{sub {gamma}p} by means of an unfolding procedure, taking not only all bin correlations into account, but also the correlation between the elastic and proton dissociative process. The obtained elastic and proton dissociative differential cross sections are analysed in a simultaneous fit, taking the full statistical covariance matrices and systematic uncertainty sources into account.

Future NTP Development Synergy Leveraged from Current J-2X Engine Development

Science.gov (United States)

Ballard, Richard O.

2008-01-01

This paper is a discussion of how the many long-lead development elements required for the realization of a future nuclear thermal propulsion (NTP) system can be effectively leveraged from the ongoing work being conducted on the J-2X engine program for the Constellation Program. Development studies conducted to date for NTP forward planning have identified a number of technical areas that will require advancement to acceptable technology readiness levels (TRLs) before they can be utilized in NTP system development. These include high-temperature, high-area ratio nozzle extension; long-life, low-NPSP. turbomachinery; and low-boiloff propellant management; and a qualified nuclear fuel element. The current J-2X program is working many of these areas that can be leveraged to support NTP development in a highly compatible and synergistic fashion. In addition to supporting technical development, there are other programmatic issues being worked in the J-2X program that can be leveraged by a future NTP development program. These include compliance with recently-evolved space system requirements such as human-rating, fault tolerance and fracture control. These and other similar mandatory system requirements have been adopted by NASA and can result in a significant technical impact beyond elevation of the root technologies required by NTP. Finally, the exploitation of experience, methodologies, and procedures developed by the J-2X program in the areas of verification, qualification, certification, altitude simulation testing, and facility definition will be especially applicable to a future NTP system. The similarities in system mission (in-space propulsion) and operational environment (vacuum, zero-gee) between J-2X and NTP make this highly synergistic. Thus, it can be $hown that the collective benefit of leveraging experience and technologies developed during the J-2X program can result in significant savings in development cost and schedule for NTP.

A measurement of the e+e- decay width of the Z0

International Nuclear Information System (INIS)

Yamartino, J.M.

1994-02-01

This thesis presents a measurement of the partial decay width of the Z 0 to e + e - using data recorded by the SLD at the SLAC Linear Collider during the 1992 run. Based on 354 nb -1 of data, the decay width, Γ ee is measured to be 82.4 ± 3.6/3.7 ± 0.8 MeV where the first error is statistical and the second is systematic. By combining this measurement of Γ ee with the SLD measurement of A LR , the magnitude of the effective vector and axial-vector coupling constants of the electron, anti g v e and anti g a e , are determined to be 0.024 ± 0.011 and 0.498 ± 0.011 respectively

A API foi desenvolvida nas linguagens C++ e Python, que são as primeiras linguagens ensinadas no curso técnico em informática do IFPB Guarabira. Os métodos implementados permitem ao robô andar para frente, andar para trás, virar à direita, virar à esquerda e obter a distância até um obstáculo à frente. A API encapsula toda a complexidade para comunicação e transmissão dos comandos. Junto a ela, está sendo desenvolvida uma Plataforma de Programação Visual  (PPV em Python. Essa plataforma, em conjunto com a API, será utilizada para tornar mais fácil e atrativa a aprendizagem de programação para os alunos iniciantes e alunos surdos. A motivação deste trabalho é utilizar a robótica como uma ferramenta de ensino, ajudando no entendimento de conceitos complexos na área de computação e de outras disciplinas, como física e matemática. Usando a PPV, os alunos poderão aprender com maior facilidade os comandos da linguagem Python, por meio de associação de imagens com os comandos. Devido a essa característica, espera-se que os alunos surdos consigam identificar com maior facilidade os comandos que estão associados às imagens.

Improved cell line IPEC-J2, characterized as a model for porcine jejunal epithelium.

Directory of Open Access Journals (Sweden)

Silke S Zakrzewski

Full Text Available Cell lines matching the source epithelium are indispensable for investigating porcine intestinal transport and barrier properties on a subcellular or molecular level and furthermore help to reduce animal usage. The porcine jejunal cell line IPEC-J2 is established as an in vitro model for porcine infection studies but exhibits atypically high transepithelial resistances (TER and only low active transport rates so that the effect of nutritional factors cannot be reliably investigated. This study aimed to properly remodel IPEC-J2 and then to re-characterize these cells regarding epithelial architecture, expression of barrier-relevant tight junction (TJ proteins, adequate TER and transport function, and reaction to secretagogues. For this, IPEC-J2 monolayers were cultured on permeable supports, either under conventional (fetal bovine serum, FBS or species-specific (porcine serum, PS conditions. Porcine jejunal mucosa was analyzed for comparison. Main results were that under PS conditions (IPEC-J2/PS, compared to conventional FBS culture (IPEC-J2/FBS, the cell height increased 6-fold while the cell diameter was reduced by 50%. The apical cell membrane of IPEC-J2/PS exhibited typical microvilli. Most importantly, PS caused a one order of magnitude reduction of TER and of trans- and paracellular resistance, and a 2-fold increase in secretory response to forskolin when compared to FBS condition. TJ ultrastructure and appearance of TJ proteins changed dramatically in IPEC-J2/PS. Most parameters measured under PS conditions were much closer to those of typical pig jejunocytes than ever reported since the cell line's initial establishment in 1989. In conclusion, IPEC-J2, if cultured under defined species-specific conditions, forms a suitable model for investigating porcine paracellular intestinal barrier function.

The process e+e- →K+K- has been studied using 1.7 ×106 events from a data sample corresponding to an integrated luminosity of 5.7 pb-1 collected with the CMD-3 detector in the center-of-mass energy range 1010-1060 MeV. The cross section is measured with about 2% systematic uncertainty and is used to calculate the contribution to the anomalous magnetic moment of the muon aμK+K- = (19.33 ± 0.40) ×10-10, and to obtain the ϕ (1020) meson parameters. We consider the relationship between the e+e- →K+K- and e+e- → KS0 KL0 cross sections and compare it to the theoretical prediction.

Subcortical band heterotopia (SBH) are malformations of the human cerebral cortex typically associated with epilepsy and cognitive delay/disability. Rodent models of SBH have demonstrated strong face validity as they are accompanied by both cognitive deficits and spontaneous seizures or reduced seizure threshold. BXD29-Tlr4 lps-2J /J recombinant inbred mice display striking bilateral SBH, partial callosal agenesis, morphological changes in subcortical structures of the auditory pathway, and display sensory deficits in behavioral tests (Rosen et al., 2013; Truong et al., 2013, 2015). Surprisingly, these mice show no cognitive deficits and have a higher seizure threshold to chemi-convulsive treatment (Gabel et al., 2013) making them different than other rodent SBH models described previously. In the present report, we perform a detailed characterization of the cellular and axonal constituents of SBH in BXD29-Tlr4 lps-2J /J mice and demonstrate that various types of interneurons and glia as well as cortical and subcortical projections are found in SBH. In addition, the length of neuronal cilia was reduced in SBH compared to neurons in the overlying and adjacent normotopic cortex. Finally, we describe additional and novel malformations of the hippocampus and neocortex present in BXD29-Tlr4 lps-2J /J mice. Together, our findings in BXD29-Tlr4 lps-2J /J mice are discussed in the context of the known neuroanatomy and phenotype of other SBH rodent models. Copyright © 2016 IBRO. Published by Elsevier Ltd.

Huber, Florian

2010-05-01

In this diploma thesis the elastic J/ψ vector meson photoproduction (ep→eJ/ψp) is studied in the decay channel J/ψ→e + e - with the H1 detector at the electron proton collider HERA. The data from the runs of the year 2007 with an integrated luminosity of 62.4 pb -1 are used. In this time HERA operated with tree different proton energies E p called high (920 GeV), medium (575 GeV) and low (460 GeV) with integrated luminosities 45.5 (high), 5.96 (medium) and 10.9 pb -1 (low). The kinematical region of vertical stroke t vertical stroke 2 , where t is the four momentum transfer at the proton vertex, and Q e 2 γp , is restricted to 40 GeV γp γp γp -b 0 vertical stroke t vertical stroke , which yields to b 0 =4.4±0.2(stat.). The cross section as a function of W γp is fitted by a power law, dσ/dW γp ∝W δ γp , and gives δ=0.66±0.07(stat.). (orig.)

Full Text Available Diodon holocanthus es una especie con cierta importancia comercial y ecológica en la comunidad de peces que forma la fauna de acompañamiento del camarón en la plataforma continental del Pacífico central Mexicano, y de la cual no se conocen aspectos reproductivos. Por lo cual se obtuvieron el periodo de reproducción, la descripción macro y microscópica de las gónadas, además de variables poblacionales como: distribución de tallas, proporción sexual y talla de madurez. En total se capturaron alrededor de 400 organismos, los cuales presentaron una talla mínima de 5.0cm, máxima de 40.3cm y promedio de 18.4cm, y fueron capturados en la plataforma continental en el Pacífico central Mexicano, desde diciembre de 1995 a diciembre de 1998. La proporción sexual fue de 1:0.86 hembras por machos (n=253. La talla a la cual el 50% de individuos presentó gónadas maduras fue 19.7cm en las hembras y 20.1cm en los machos. Los organismos con las menores tallas que presentaron gónadas en fase de maduración midieron 12.2cm (hembras y 13cm (machos. En ambos sexos el desarrollo de la gónada se determinó con base en una escala de maduración de cuatro estadios. En el proceso de maduración de los ovocitos se identificaron cinco fases de desarrollo. El patrón de desarrollo de los ovocitos es de tipo asincrónico, lo que significa que la especie se puede reproducir varias veces al año. El desarrollo del testículo es de tipo lobular como en la mayoría de los peces teleósteos. El índice gonadosomático sugiere que el periodo de reproducción se concentra en los meses de junio, y de septiembre a diciembre.

Development of the fast reactor group constant set JFS-3-J3.2R based on the JENDL-3.2

Chiba, G

2002-01-01

It is reported that the fast reactor group constant set JFS-3-J3.2 based on the newest evaluated nuclear data library JENDL3.2 has a serious error in the process of applying the weighting function. As the error affects greatly nuclear characteristics, and a corrected version of the reactor constant set, JFS-3-J3.2R, was developed, as well as lumped FP cross sections. The use of JFS-3-J3.2R improves the results of analyses especially on sample Doppler reactivity and reaction rate in the blanket region in comparison with those obtained using the JFS-3-J3.2.

Although the T-cell subset differentiation pathway has been characterized extensively from the view of host gene regulation, the effects of genes of the pathogen on T-cell subset differentiation during infection have yet to be elucidated. Especially, the bacterial genes that are responsible for this shift have not yet been determined. Utilizing a single-gene-mutation Listeria panel, we investigated genes involved in the host-pathogen interaction that are required for the initiation of T-cell subset differentiation in the early phase of pathogen infection. We demonstrate that the induction of T helper types 1 and 2 (Th1 and Th2) subsets are separate phenomena and are mediated by distinct Listeria genes. We identified several candidate Listeria genes that appear to be involved in the host-Listeria interaction. Among them, arpJ is the strongest candidate gene for inhibiting Th2 subset induction. Furthermore, the analysis utilizing arpJ-deficient Listeria monocytogenes (Lm) revealed that the tumor necrosis factor (TNF) superfamily (Tnfsf) 9-TNF receptor superfamily (Tnfrsf) 9 interaction inhibits the Th2 response during Lm infection. arpJ is the candidate gene for inhibiting Th2 T-cell subset induction. The arpJ gene product influences the expression of Tnfsf/Tnfrsf on antigen-presenting cells and inhibits the Th2 T-cell subset differentiation during Listeria infection. © The Author 2015.

EPCGen2 Pseudorandom Number Generators: Analysis of J3Gen

Alberto Peinado

2014-04-01

Full Text Available This paper analyzes the cryptographic security of J3Gen, a promising pseudo random number generator for low-cost passive Radio Frequency Identification (RFID tags. Although J3Gen has been shown to fulfill the randomness criteria set by the EPCglobal Gen2 standard and is intended for security applications, we describe here two cryptanalytic attacks that question its security claims: (i a probabilistic attack based on solving linear equation systems; and (ii a deterministic attack based on the decimation of the output sequence. Numerical results, supported by simulations, show that for the specific recommended values of the configurable parameters, a low number of intercepted output bits are enough to break J3Gen. We then make some recommendations that address these issues.

To investigate the changes of Apo-J and Omi/HtrA2 protein expression in rats with intracerebral hemorrage. 150 SD adult rats were randomly divided into 3 groups: (1) Normal Control (NC) group, (2) Sham group, (3) Intracerebral Hemorrage (ICH) group. The data were collected at 6h, 12h, 1d, 2d, 3d, 5d and 7d. Apoptosis was measured by Tunel staining. The distributions of the Apo-J and Omi/HtrA2 proteins were determined by immunohistochemical staining. The levels of Apo-J mRNA and Omi/HtrA2 mRNA expressions were examined by RT-PCR. Apoptosis in ICH group was higher than Sham and NC groups (p＜0.05). Both the Apo-J and Omi/HtrA2 expression levels were increased in the peripheral region of hemorrhage, with a peak at 3d. The Apo-J mRNA level positively correlated with HtrA2 mRNA level in ICH group (r=0.883, p＜0.001). The expressions of Apo-J and Omi/HtrA2 paralelly increased in peripheral region of rat cerebral hemorrhage. Local high expressed Apo-J in the peripheral regions might play a neuroprotective role by inhibiting apoptosis via Omi/HtrA2 pathway after hemorrhage. Copyright © 2018. Published by Elsevier Inc.

Observations of the J = 2 → 1 transition of carbon monoxide in interstellar clouds

International Nuclear Information System (INIS)

Goldsmith, P.F.

1975-01-01

A spectral line radiometer system for operation at a wavelength of 1.3 mm (ν = 230 GHz) was constructed and used for astronomical observations. Observations were made of the 12 CO J = 2 → 1 line in nine astronomical sources. The 13 CO J = 2 → 1 line was measured in three molecular clouds--Orion A, NGC 2024, and OMC 2. The 12 C 18 O J = 2 → 1 line has been searched for, but not detected in Orion A. It was found that the temperatures of the 12 CO J = 1 → 0 lines are equal to or slightly lower than those of the corresponding J = 1 → 0 lines. The significance of the differences observed is reduced by the uncertainties in the calibrations at the two frequencies. These measurements are consistent with the 12 CO transitions being optically thick and thermalized. The 13 CO J = 2 → 1 lines are also approximately equal in intensity to the J = 1 → 0 lines. This is not consistent with both transitions being optically thin. The implications of these measurements in terms of clumped and low density models are discussed. In the proposed low density model which fits the CO data but encounters difficulties explaining the emission from other molecules, the molecular hydrogen density in the CO-emitting region is about 2 x 10 3 cm -3 . The nondetection of the J = 2 → 1 line of the 12 C 18 O species in Orion A places an upper limit on the hydrogen density of between 2 x 10 3 cm -3 and 4 x 10 +3 cm -3 , depending on the kinetic temperature in the cloud, for that component which is optically thin. A model for the central region of the Orion A molecular cloud is proposed in which high density (n/sub H/ greater than or equal to 10 6 cm -3 ) clumps occupying a few percent of the volume are embedded in a low density (n/sub H 2 / approximately 2 x 10 3 cm -3 ) interclump medium

We observe a sample of eight evolved stars in the Galactic bulge in the CO J = 2-1 line using the Submillimeter Array with angular resolution of 1''-4''. These stars have been detected previously at infrared wavelengths, and several of them have OH maser emission. We detect CO J = 2-1 emission from three of the sources in the sample: OH 359.943 +0.260, [SLO2003] A12, and [SLO2003] A51. We do not detect the remaining five stars in the sample because of heavy contamination from the galactic CO emission. Combining CO data with observations at infrared wavelengths constraining dust mass loss from these stars, we determine the gas-to-dust ratios of the Galactic bulge stars for which CO emission is detected. For OH 359.943 +0.260, we determine a gas mass-loss rate of 7.9 ({+-}2.2) Multiplication-Sign 10{sup -5} M {sub Sun} yr{sup -1} and a gas-to-dust ratio of 310 ({+-}89). For [SLO2003] A12, we find a gas mass-loss rate of 5.4 ({+-}2.8) Multiplication-Sign 10{sup -5} M {sub Sun} yr{sup -1} and a gas-to-dust ratio of 220 ({+-}110). For [SLO2003] A51, we find a gas mass-loss rate of 3.4 ({+-}3.0) Multiplication-Sign 10{sup -5} M {sub Sun} yr{sup -1} and a gas-to-dust ratio of 160 ({+-}140), reflecting the low quality of our tentative detection of the CO J = 2-1 emission from A51. We find that the CO J = 2-1 detections of OH/IR stars in the Galactic bulge require lower average CO J = 2-1 backgrounds.

A beam optics scheme has been designed [ 1 ] for the Future Circular Collider- e + e − (FCC-ee). The main characteristics of the design are: beam energy 45 to 175 GeV, 100 km circumference with two interaction points (IPs) per ring, horizontal crossing angle of 30 mrad at the IP and the crab-waist scheme [ 2 ] with local chromaticity correction. The crab-waist scheme is implemented within the local chromaticity correction system without additional sextupoles, by reducing the strength of one of the two sextupoles for vertical chromatic correction at each side of the IP. So- called “tapering" of the magnets is applied, which scales all fields of the magnets according to the local beam energy to compensate for the effect of synchrotron radiation (SR) loss along the ring. An asymmetric layout near the interaction region reduces the critical energy of SR photons on the incoming side of the IP to values below 100 keV, while matching the geometry to the beam line of the FCC proton collider (FCC-hh) [ 3 ] as clos...

We present the results of a program to map the Sh2-235 molecular cloud complex in the CO and 13 CO  J  = 2 − 1 transitions using the Heinrich Hertz Submillimeter Telescope. The map resolution is 38″ (FWHM), with an rms noise of 0.12 K brightness temperature, for a velocity resolution of 0.34 km s −1 . With the same telescope, we also mapped the CO J  = 3 − 2 line at a frequency of 345 GHz, using a 64 beam focal plane array of heterodyne mixers, achieving a typical rms noise of 0.5 K brightness temperature with a velocity resolution of 0.23 km s −1 . The three spectral line data cubes are available for download. Much of the cloud appears to be slightly sub-thermally excited in the J  = 3 level, except for in the vicinity of the warmest and highest column density areas, which are currently forming stars. Using the CO and 13 CO  J  = 2 − 1 lines, we employ an LTE model to derive the gas column density over the entire mapped region. Examining a 125 pc 2  region centered on the most active star formation in the vicinity of Sh2-235, we find that the young stellar object surface density scales as approximately the 1.6-power of the gas column density. The area distribution function of the gas is a steeply declining exponential function of gas column density. Comparison of the morphology of ionized and molecular gas suggests that the cloud is being substantially disrupted by expansion of the H ii regions, which may be triggering current star formation.

The even parity 4pnp J=0, 1, 2 doubly excited autoionizing states of neutral calcium in an atomic beam are investigated by a two-step isolated core excitation (ICE) method using two different combinations of polarization of the laser beams. The different excited energy levels are assigned to nine autoionizing Rydberg series 4p 1/2,3/2 np J=0, 1, 2 for 8≤n≤22. The theoretical interpretation is achieved by a combination of the eigenchannel R-matrix theory and the multichannel quantum defect (MQDT) method. Two, five and six closed interacting channels are introduced for the J=0, J=1 and J=2 series respectively. Theoretical energy level positions, autoionization widths and excitation profiles are compared with the experimental data, confirming the identification of the observed structures and providing evidence of extended mixing between the 4p 1/2 np and 4p 3/2 np series.

Neutral-current four-fermion production, e+e- -> ffff is studied in 0.7/fb of data collected with the L3 detector at LEP at centre-of-mass energies root(s)=183-209GeV. Four final states are considered: qqvv, qqll, llll and llvv, where l denotes either an electron or a muon. Their cross sections are measured and found to agree with the Standard Model predictions. In addition, the e+e- -> Zgamma* -> ffff process is studied and its total cross section at the average centre-of-mass energy 196.6GeV is found to be 0.29 +/- 0.05 +/- 0.03 pb, where the first uncertainty is statistical and the second systematic, in agreement with the Standard Model prediction of 0.22 pb. Finally, the mass spectra of the qqll final states are analysed to search for the possible production of a new neutral heavy particle, for which no evidence is found.

A search for the Higgsstrahlung process e+e- -> hZ is described, where the neutral Higgs boson h is assumed to decay into hadronic final states. In order to be sensitive to a broad range of models, the search is performed independent of the flavour content of the Higgs boson decay. The analysis is based on e+e- collision data collected by the OPAL detector at energies between 192 GeV and 209 GeV. The search does not reveal any significant excess over the Standard Model background prediction. Results are combined with previous searches at energies around 91 GeV and at 189 GeV. A limit is set on the product of the cross-section and the hadronic branching ration of the Higgs boson, as a function of the Higgs boson mass. Assuming the hZ coupling predicted by the Standard Model, and a Higgs boson decaying only into hadronic final states, a lower bound of 104 GeV/c2 is set on the mass at the 95% confidence level.

Current models of e+e- annihilation to baryons are reviewed and compared to the available data. Since the experimental predictions of most models are found to be very similar, an attempt is made to find differences between them which can be tested as more data become available. (author)

To characterise ocular pigment abnormalities associated with iris atrophy in DBA/2J mice as a model for human pigment dispersion syndrome. Immunohistochemistry, electron and light microscopy were performed to examine the eyes of DBA/2J mice ranging in age from 2.5 to 18 months old. The focus of our study was the description of the ultrastructural modifications in the irides of DBA/2J mice. The DBA/2J mice presented modifications in the melanosomes in all the pigmented parts of the eye, including the retinal pigment epithelial cells and choroidal melanocytes of the ciliary pigment epithelium. The extracellular matrix of the iris stroma disappeared with ageing. Pigmented cells detached from the iris and migrated into the trabecular meshwork exclusively on the anterior iris surface. These cells were identified as macrophages by immunohistochemistry and electron microscopy. There was no evidence that melanocytes or iris pigment epithelial cells migrated into the trabecular meshwork, but they became more and more depigmented. The aqueous outflow was blocked by pigment-laden cells, but not by cellular debris or melanosomes. No substantial amount of extracellular melanosomes was observed. The morphology of melanosomes is aberrant in all pigment cells in the eyes of DBA/2J mice. We conclude that the disease process begins with the transfer of both immature melanosomes from the iris pigment epithelium (IPE) and melanocytes to macrophages, which subsequently migrate into the trabecular meshwork. Accumulating macrophages cause a blockade of the chamber angle. As the disease progresses, the IPE, melanocytes and iris stroma, including blood vessels, disappear, leading to iris atrophy. It is speculated that the loss of these pigment cells is partly caused by reduction of the iris stroma.

Polyethylene glycols (PEGs) are a class of non-toxic, non-volatile, biocompatible, and widely available polymers. In this work, we synthesized N-ethyl-N-(2-(2-(2-methoxyethoxy)ethoxy)ethyl)-2-aminoethanol (EE3AE) that combines the properties of PEG and amines, and N-decyl-N-ethyl-2-aminoethanol (DEAE). Their performances to capture SO2 were studied at different temperatures, pressures, and absorption times. The interaction between the absorbents and SO2 were characterized by NMR and FTIR techniques. It was demonstrated that both EE3AE and DEAE could absorb SO2 efficiently, and there existed chemical and physical interactions between the absorbents and SO2. In particular, the absorption capacity of EE3AE could be as high as 1.09 g SO2 per g EE3AE at 1 atm. The absorption capacity of EE3AE was much larger than that of DEAE because the ether group in the EE3AE interacted with SO2 more strongly than the alkyl group in the DEAE. The SO2 absorbed by EE3AE could be stripped out by bubbling N2 or by applying a vacuum and the EE3AE could be reused. Moreover, both absorbents exhibited a high SO2-CO2 selectivity.

Decadal variation in Earth's oblateness (J2) from satellite laser ranging data

For four decades, satellite laser ranging has recorded the global nature of the long-wavelength hydrological mass redistribution within the Earth system, which results in significant variations in the Earth's dynamical oblateness, characterized by the second degree zonal geopotential spherical harmonic J2 (or C20). Analysis of the J2 time-series has shown a significant variation related to the strong El Niño-Southern Oscillation events with periods of 2-6 yr. In particular, the variation related to the powerful 2015-2016 El Niño that peaked during 2015 November-December was one of the strongest on record, comparable with the 1982-1983 and 1997-1998 events. In this study, we investigate further the hydrological mass transfer between atmosphere-ocean-land and their signature in the decadal variations of J2 with timescales of ˜10 yr. We found that the ˜6.4-yr variations can be accounted for by the atmosphere and ocean mass variations based on the improved Atmosphere-Ocean De-aliasing data, and the observed decadal variation in J2 correlates well with the decadal tropical variability characterized by the 5-yr running mean of the El Niño-Southern Oscillation Index, although existing physical models, especially the land water storage, are limited for the purpose of further studies of the excitation.

We report on the first measurement of inclusive J/$\\psi$ elliptic flow, $v_2$, in heavy-ion collisions at the LHC. The measurement is performed with the ALICE detector in Pb-Pb collisions at $\\sqrt{s_{NN}}$ = 2.76 TeV in the rapidity range 2.5 < y < 4.0. The dependence of the J/$\\psi v_2$ on the collision centrality and on the J/$\\psi$ transverse momentum is studied in the range 0 $\\le p_T \\lt $10 GeV/c. For semi-central Pb-Pb collisions at $\\sqrt{s_{NN}}$ = 2.76 TeV, an indication of non-zero v2 is observed with a maximum value of v2 = 0.116 $\\pm$ 0.046(stat.) $\\pm$ 0.029(syst.) for J/$\\psi$ in the transverse momentum range 2 $\\le p_T \\lt$ 4 GeV/c. The elliptic flow measurement complements the previously reported ALICE results on the inclusive J/$\\psi$ nuclear modification factor and favors the scenario of a significant fraction of J/$\\psi$ production from charm quarks in a deconfined partonic phase.

The nature of the E-E' bonds (E, E' = S and Se) in glutathione disulfide ( 1 ) and derivatives 2 - 3 , respectively, was elucidated by applying quantum theory of atoms-in-molecules (QTAIM) dual functional analysis (QTAIM-DFA), to clarify the basic contribution of E-E' in the biological redox process, such as the glutathione peroxidase process. Five most stable conformers a - e were obtained, after applying the Monte-Carlo method then structural optimizations. In QTAIM-DFA, total electron energy densities H b ( r c ) are plotted versus H b ( r c ) - V b ( r c )/2 at bond critical points (BCPs), where V b ( r c ) are potential energy densities at BCPs. Data from the fully optimized structures correspond to the static nature. Those containing perturbed structures around the fully optimized one in the plot represent the dynamic nature of interactions. The behavior of E-E' was examined carefully. Whereas E-E' in 1a - 3e were all predicted to have the weak covalent nature of the shared shell interactions, two different types of S-S were detected in 1 , depending on the conformational properties. Contributions from the intramolecular non-covalent interactions to stabilize the conformers were evaluated. An inverse relationship was observed between the stability of a conformer and the strength of E-E' in the conformer, of which reason was discussed.

distributed program, including test data, etc.: 114868 No. of bytes in distributed program, including test data, etc.: 963939 Distribution format: tar.gz Programming language: FORTRAN 77/90. Computer: Any computer with Fortran compiler, the program is tested with GNU Fortran compiler and Intel Fortran compiler. Operating system: UNIX, Linux and Windows. RAM: About 2.0 MB. Classification: 11.2. Nature of problem: Production of charmonium, (cb¯)-quarkonium and bottomonium via e+e- annihilation channel around the Z0 peak. Solution method: The production of heavy (QQ)-quarkonium (Q,Q‧=b,c) via e+e- annihilation are estimated by using the improved trace technology. The (QQ)-quarkonium in color-singlet 1S-wave state, 1P-wave state, and the color-octet 1S-wave states have been studied within the framework of non-relativistic QCD. The code with option can generate weighted and unweighted events conveniently, in particular, the unweighted events are generated by using an improved hit-and-miss approach so as to improve the generating efficiency. Restrictions: The generator is aimed at the production of double heavy quarkonium through e+e- annihilation at the Z0 peak. The considered processes are those that are associated with two heavy quark jets, which could provide sizable quarkonium events around the Z0 peak. Running time: It depends on which option one chooses to match PYTHIA when generating the heavy quarkonium events. Typically, for the production of the S-wave quarkonium states, if setting IDPP=2 (unweighted events), then it takes about 2 h on a 2.9 GHz AMD Athlon (tm) II×4 635 Processor machine to generate 105 events; if setting IDPP=3 (weighted events), it takes only ˜16 min to generate 105 events. For the production of the P-wave quarkonium states, the time will be almost one hundred times longer than the case of the S-wave quarkonium.

Changes in J2, resulting from past and present changes in Earth's climate, are traditionally observed by Satellite Laser ranging (SLR). Assuming an elastic Earth, it is possible to infer changes in J2 from changes in Earth's shape observed by GPS. We compare estimates of non-secular J2 changes from
