  1. Production of Actinium-225 via High Energy Proton Induced Spallation of Thorium-232

    International Nuclear Information System (INIS)

    The science of cancer research is currently expanding its use of alpha particle emitting radioisotopes. Coupled with the discovery and proliferation of molecular species that seek out and attach to tumors, new therapy and diagnostics are being developed to enhance the treatment of cancer and other diseases. This latest technology is commonly referred to as Alpha Immunotherapy (AIT). Actinium-225/Bismuth-213 is a parent/daughter alpha-emitting radioisotope pair that is highly sought after because of the potential for treating numerous diseases and its ability to be chemically compatible with many known and widely used carrier molecules (such as monoclonal antibodies and proteins/peptides). Unfortunately, the worldwide supply of actinium-225 is limited to about 1,000mCi annually and most of that is currently spoken for, thus limiting the ability of this radioisotope pair to enter into research and subsequently clinical trials. The route proposed herein utilizes high energy protons to produce actinium-225 via spallation of a thorium-232 target. As part of previous R and D efforts carried out at Argonne National Laboratory recently in support of the proposed US FRIB facility, it was shown that a very effective production mechanism for actinium-225 is spallation of thorium-232 by high energy proton beams. The base-line simulation for the production rate of actinium-225 by this reaction mechanism is 8E12 atoms per second at 200 MeV proton beam energy with 50 g/cm2 thorium target and 100 kW beam power. An irradiation of one actinium-225 half-life (10 days) produces ∼100 Ci of actinium-225. For a given beam current the reaction cross section increases slightly with energy to about 400 MeV and then decreases slightly for beam energies in the several GeV regime. The object of this effort is to refine the simulations at proton beam energies of 400 MeV and above up to about 8 GeV. Once completed, the simulations will be experimentally verified using 400 MeV and 8 GeV protons

    Actinium-225 is a promising isotope for targeted-α therapy. Unfortunately, progress in developing chelators for medicinal applications has been hindered by a limited understanding of actinium chemistry. This knowledge gap is primarily associated with handling actinium, as it is highly radioactive and in short supply. Hence, AcIII reactivity is often inferred from the lanthanides and minor actinides (that is, Am, Cm), with limited success. Here we overcome these challenges and characterize actinium in HCl solutions using X-ray absorption spectroscopy and molecular dynamics density functional theory. The Ac-Cl and Ac-OH2O distances are measured to be 2.95(3) and 2.59(3) Å, respectively. The X-ray absorption spectroscopy comparisons between AcIII and AmIII in HCl solutions indicate AcIII coordinates more inner-sphere Cl1- ligands (3.2+/-1.1) than AmIII (0.8+/-0.3). These results imply diverse reactivity for the +3 actinides and highlight the unexpected and unique AcIII chemical behaviour.

  4. Separation of Actinium 227 from the uranium minerals

    International Nuclear Information System (INIS)

    The purpose of this work was to separate Actinium 227, whose content is 18%, from the mineral carnotite found in Gomez Chihuahua mountain range in Mexico. The mineral before processing is is pre-concentrated and passed, first through anionic exchange resins, later the eluate obtained is passed through cationic resins. The resins were 20-50 MESH QOWEX and 100-200 MESH 50 X 8-20 in some cased 200-400 MESH AG 50W-X8, 1X8 in other cases. The eluates from the ionic exchange were electrodeposited on stainless steel polished disc cathode and platinum electrode as anode; under a current ODF 10mA for 2.5 to 5 hours and of 100mA for .5 of an hour. it was possible to identify the Actinium 227 by means of its descendents, TH-227 and RA-223, through alpha spectroscopy. Due to the radiochemical purity which the electro deposits were obtained the Actinium 227 was low and was not quantitatively determined. A large majority of the members of the natural radioactive series 3 were identified and even alpha energies reported in the literature with very low percentages of non-identified emissions were observed. We conclude that a more precise study is needed concerning ionic exchange and electrodeposit to obtain an Actinium 227 of radiochemical purity. (Author)

  8. Analysis of the gamma spectra of the uranium, actinium, and thorium decay series

    International Nuclear Information System (INIS)

    This report describes the identification of radionuclides in the uranium, actinium, and thorium series by analysis of gamma spectra in the energy range of 40 to 1400 keV. Energies and absolute efficiencies for each gamma line were measured by means of a high-resolution germanium detector and compared with those in the literature. A gamma spectroscopy method, which utilizes an on-line computer for deconvolution of spectra, search and identification of each line, and estimation of activity for each radionuclide, was used to analyze soil and uranium tailings, and ore

    The present study explores the use of alpha-particle-emitting, bone-seeking agents as candidates for targeted radiotherapy. Actinium and thorium 1,4,7,10 tetraazacyclododecane N,N',N'',N''' 1,4,7,10-tetra(methylene) phosphonic acid (DOTMP) and thorium-diethylene triamine N,N',N'' penta(methylene) phosphonic acid (DTMP) were prepared and their biodistribution evaluated in conventional Balb/C mice at four hours after injection. All three bone-seeking agents showed a high uptake in bone and a low uptake in soft tissues. Among the soft tissue organs, only kidney had a relatively high uptake. The femur/kidney ratios for 227Th-DTMP, 228-Ac-DOTMP and 227Th-DOTMP were 14.2, 7.6 and 6.0, respectively. A higher liver uptake of 228Ac-DOTMP was seen than for 227Th-DTMP and 227Th-DOTMP. This suggests that some demetallation of the 228Ac-DOTMP complex had occurred. The results indicate that 225Ac-DOTMP, 227Th-DOTMP and 227Th-DTMP have promising properties as potential therapeutic bone-seeking agents.

    To study exotic nuclides at the borders of stability with laser ionization and spectroscopy techniques, highest efficiencies in combination with a high spectral resolution are required. These usually opposing requirements are reconciled by applying the in-gas-laser ionization and spectroscopy (IGLIS) technique in the supersonic gas jet produced by a de Laval nozzle installed at the exit of the stopping gas cell. Carrying out laser ionization in the low-temperature and low density supersonic gas jet eliminates pressure broadening, which will significantly improve the spectral resolution. This article presents the required modifications at the Leuven Isotope Separator On-Line (LISOL) facility that are needed for the first on-line studies of in-gas-jet laser spectroscopy. Different geometries for the gas outlet and extraction ion guides have been tested for their performance regarding the acceptance of laser ionized species as well as for their differential pumping capacities. The specifications and performance of the temporarily installed high repetition rate laser system, including a narrow bandwidth injection-locked Ti:sapphire laser, are discussed and first preliminary results on neutron-deficient actinium isotopes are presented indicating the high capability of this novel technique.

  11. Groundwater seepage from the Ranger uranium mine tailings dam: radioisotopes of radium, thorium and actinium. Supervising Scientist report 106

    International Nuclear Information System (INIS)

    Monitoring of bores near the Ranger uranium mine tailings dam has revealed deterioration in water quality in several bores since 1983. In a group of bores to the north of the dam, increases have been observed of up to 500 times for sulphate concentrations and of up to 5 times for 226Ra concentrations. Results are presented here of measurements of members of the uranium, thorium and actinium decay series in borewater samples collected between 1985 and 1993. In particular, measurements of all four naturally-occurring radium isotopes have been used in an investigation of the mechanism of radium concentration changes. For the most seepage-affected bores the major findings of the study include: 228Ra/226Ra 223Ra /226Ra and 224Ra/228Ra ratios all increased over the course of the study; barium concentrations show high seasonal variability, being lower in November than May, but strontium concentrations show a steady increase with time. Calculations show that the groundwater is probably saturated with respect to barite but not with respect to celestite or anglesite; sulphide concentrations are low in comparison with sulphate, and are higher in November than in May; and 227Ac concentrations have increased with time, but do not account for the high 223Ra/226Ra ratios. It is concluded on the basis of these observations that increases in Ra isotope concentrations observed in a number of seepage-affected bores arise from increases in salinity leading to desorption of radium from adsorption sites in the vicinity of the bore rather by direct transport of radium from the tailings. Increased salinity is also causing the observed increases in 227Ac and strontium concentrations, while formation of a barite solid phase in the groundwater is causing the removal of some radium from solution. This is the cause of the increasing radium isotope ratios noted above

  12. Linear free energy relationship applied to trivalent cations with lanthanum and actinium oxide and hydroxide structure

    International Nuclear Information System (INIS)

    Linear free energy relationships for trivalent cations with crystalline M2O3 and, M(OH)3 phases of lanthanides and actinides were developed from known thermodynamic properties of the aqueous trivalent cations, modifying the Sverjensky and Molling equation. The linear free energy relationship for trivalent cations is as ΔGf,MvX0=aMvXΔGn,M3+0+bMvX+βMvXrM3+, where the coefficients aMvX, bMvX, and βMvX characterize a particular structural family of MvX, rM3+ is the ionic radius of M3+ cation, ΔGf,MvX0 is the standard Gibbs free energy of formation of MvX and ΔGn,M3+0 is the standard non-solvation free energy of the cation. The coefficients for the oxide family are: aMvX=0.2705, bMvX=-1984.75 (kJ/mol), and βMvX=197.24 (kJ/molnm). The coefficients for the hydroxide family are: aMvX=0.1587, bMvX=-1474.09 (kJ/mol), and βMvX=791.70 (kJ/molnm).

  13. Purification of selenium from thorium, uranium, radium, actinium and potassium impurities for low background measurements

    International Nuclear Information System (INIS)

    A technique of selenium purification from 232Th, 238U, 226,228Ra, 227Ac and 40K was developed. This technique is simple to perform and employs a minimum number of highly pure reagents (bidistilled water, nitric acid). Operations carried out during purification (elution, evaporation) practically exclude losses of the target product (chemical yields of Se > 99%). A test purification of 100 g of selenium was carried out using this technique. The efficiency of this technique was confirmed by low background gamma spectrometry of the purified selenium sample. Distribution coefficients of Th, U, Ra and Ac on DOWEX 50W- x 8 cation-exchange resin at different concentrations of selenium and nitric acid were experimentally determinated. Instrumental neutron activation analysis of bidistilled water, deionized water and nitric acid was performed. (orig.)

    Clinical therapeutic studies using {sup 225}Ac-labeled antibodies have begun. Of major concern is renal toxicity that may result from the three alpha-emitting progeny generated following the decay of {sup 225}Ac. The purpose of this study was to determine the amount of {sup 225}Ac and non-equilibrium progeny in the mouse kidney after the injection of {sup 225}Ac-huM195 antibody and examine the dosimetric consequences. Groups of mice were sacrificed at 24, 96 and 144 h after injection with {sup 225}Ac-huM195 antibody and kidneys excised. One kidney was used for gamma ray spectroscopic measurements by a high-purity germanium (HPGe) detector. The second kidney was used to generate frozen tissue sections which were examined by digital autoradiography (DAR). Two measurements were performed on each kidney specimen: (1) immediately post-resection and (2) after sufficient time for any non-equilibrium excess {sup 213}Bi to decay completely. Comparison of these measurements enabled estimation of the amount of excess {sup 213}Bi reaching the kidney ({gamma}-ray spectroscopy) and its sub-regional distribution (DAR). The average absorbed dose to whole kidney, determined by spectroscopy, was 0.77 (SD 0.21) Gy kBq{sup -1}, of which 0.46 (SD 0.16) Gy kBq{sup -1} (i.e. 60%) was due to non-equilibrium excess {sup 213}Bi. The relative contributions to renal cortex and medulla were determined by DAR. The estimated dose to the cortex from non-equilibrium excess {sup 213}Bi (0.31 (SD 0.11) Gy kBq{sup -1}) represented {approx}46% of the total. For the medulla the dose contribution from excess {sup 213}Bi (0.81 (SD 0.28) Gy kBq{sup -1}) was {approx}80% of the total. Based on these estimates, for human patients we project a kidney-absorbed dose of 0.28 Gy MBq{sup -1} following administration of {sup 225}Ac-huM195 with non-equilibrium excess {sup 213}Bi responsible for approximately 60% of the total. Methods to reduce renal accumulation of radioactive progeny appear to be necessary for the

    Branching fraction and asymmetry measurements of charmless $B^+\\to K^{*+}h^+_1h^-_2$ (where $h_{1,2}$ = $K$, $\\pi$) decays are presented, using a data sample of 232 million $\\Upsilon(4S) \\to$ $BB$ decays collected with the BaBar detector at the SLAC PEP-II asymmetric-energy $B$ factory. Using a maximum likelihood fit, the following branching fraction results were obtained: ${\\cal B}$($B^+ \\to K^{*+}K^+ K^-)$ = (36.2 $\\pm$ 3.3 $\\pm$ 3.6) $\\times$ 10$^{-6}$ and ${\\cal B}$($B^+$ $\\to$ $K^{*+}\\pi^+\\pi^-$) = (75.3 $\\pm$ 6.0 $\\pm$ 8.1) $\\times$ 10$^{-6}$. Upper limits were set for ${\\cal B}$($B^+$ $\\to$ $K^{*+}\\pi^+ K^-$) $<$ 11.8 $\\times$ 10$^{-6}$ and ${\\cal B}$($B^+$ $\\to$ $K^{*+}K^+ \\pi^-$) $<$ 6.1 $\\times$ 10$^{-6}$ at 90% confidence level. The charge asymmetries for the decays $B^+ \\to K^{*+}K^+ K^-$ and $B^+$ $\\to$ $K^{*+}\\pi^+\\pi^-$ were measured to be ${\\cal A}_{K^*KK} = 0.11 \\pm 0.08 \\pm 0.03$ and ${\\cal A}_{K^*\\pi\\pi} = 0.07 \\pm 0.07 \\pm 0.04$, respectively.

    1999-01-01

    A k-bitonic sort which generalizes the bitonic sort is proposed. The theorem of the bitonic sort, which merges two monotonic sequences into one order sequence, is extended into the theorem of k-bitonic sort. The k-bitonic sort merges K (=2k or 2k-1) monotonic sequences into one order sequence in steps, where k=[K/2] is an integer and k≥1. The k-bitonic sort is the Batcher’s bitonic sort when k=1.

  3. New Results from Super-K and K2K

    CERN Document Server

    Wilkes, R J

    2002-01-01

    This paper summarizes recent (as of SSI-02, in some cases updated in November, 2002) results from the Super-Kamiokande and K2K experiments. The interpretation of Super-Kamiokande results on atmospheric and solar neutrinos provides strong evidence for neutrino oscillations, hence non-zero neutrino mass. While statistics are still limited, K2K data are consistent with Super-Kamiokande results on neutrino oscillations. The effort to reconstruct Super-Kamiokande following a cascade of phototube implosions in November, 2001 is described. Plans for the future are also discussed.

    We perform a Dalitz plot analysis of about 100,000 D{sub s}{sup +} decays to K{sup +}K{sup -}{pi}{sup +} and measure the complex amplitudes of the intermediate resonances which contribute to this decay mode. We also measure the relative branching fractions of D{sub s}{sup +} {yields} K{sup +}K{sup +}{pi}{sup -} and D{sub s}{sup +} {yields} K{sup +}K{sup +}K{sup -}. For this analysis we use a 384 fb{sup -1} data sample, recorded by the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider running at center-of-mass energies near 10.58 GeV.

    We have studied the Cabibbo-suppressed decay mode D^0 into K^+ K^- pi^0 using a Dalitz plot technique and find the strong phase difference delta_D [defined as delta_(K*^- K^+) - delta_(K*^+ K^-)] = 332 degrees +- 8 degrees +- 11 degrees and relative amplitude r_D [defined as a_(K*^- K^+) / a_(K*^+ K^-)] = 0.52 +- 0.05 +- 0.04.

    Aigrain, Suzanne; Parviainen, Hannu; Pope, Benjamin

    2016-05-01

    K2SC (K2 Systematics Correction) models instrumental systematics and astrophysical variability in light curves from the K2 mission. It enables the user to remove both position-dependent systematics and time-dependent variability (e.g., for transit searches) or to remove systematics while preserving variability (for variability studies). K2SC automatically computes estimates of the period, amplitude and evolution timescale of the variability for periodic variables and can be run on ASCII and FITS light curve files. Written in Python, this pipeline requires NumPy, SciPy, MPI4Py, Astropy (ascl:1304.002), and George (ascl:1511.015).

    For any perfect field k a triangulated category of K-motives DK_(k) is constructed in the style of Voevodsky's construction of the category DM_(k). To each smooth k-variety X the K-motive is associated in the category DK_(k). Also, it is shown that K_n(X)=DK_(k)(M_K(X)[n],M_K(pt)), where K(X) is Quillen's K-theory of X.

    We investigate the K^- ^3He and K^+K^- interactions in the reaction pd -> ^3He K^+K^- near threshold and compare our model calculations with data from the MOMO experiment at COSY-Juelich. The data do not support a strong attraction between the K^- and ^3He system needed for formation of deeply bound K^- nuclear states. We also estimate upper limits for the a_0(980) and f_0(980) contributions to the produced K^+ K^- pairs.

    We investigate the K- He3 and K+K- interactions in the reaction pd→ He3 K+K- near threshold and compare our model calculations with data from the MOMO experiment at COSY-Jülich. A large attractive effective K-p amplitude would give a significant K- He3 final-state interaction effect, which is not supported by the experimental data. We also estimate upper limits for the a0(980) and f0(980) contributions to the produced K+K- pairs.

    2003-01-01

    A Hamiltonian [k, k + 1]-factor is a [k, k + 1]-factor containing a Hamiltonian cycle. A simple graph G of order n is n/2-critical if δ(G) ≥ n/2 but δ(G - e) < n/2 for any edge e ∈ E(G). Let k ≥ 2 be an integer and G be an n/2-critical graph with n ≥ 4k - 6 and n ≥ 7. In this paper it is proved that for any given Hamiltonian cycle C of G, G has a [k, k + 1]-factor containing C. This result is an improvement on some recent results about the existence of Hamiltonian [k, k + 1]-factor.%本文考虑n/2-临界图中Hamiltonian[k,k+1]-因子的存在性.Hamiltonian[k,k+1]-因子是指包含Hamiltonian圈的[k,k+1]-因子;给定阶数为n的简单图G,若δ(G)≥n/2而δ(G\\e)<n/2(对任意的e∈E(G)),则称G为n/2-临界图.设k为大于等于2的整数,G为n/2-临界图(其中n≥4k-6且n≥7),我们证明了对于G的任何Hamiltonian圈C,G中必存在包含C的[k,k+1]-因子.该结果改进了现有的一些有关Hamiltonian[k,k+1]-因子存在性的结果.

    We report observations of the b --> d penguin-dominated decays B+ --> K0bar K+ and B0 --> K0 K0bar in approximately 350 million Upsilon(4S) --> BBbar decays collected with the BaBar detector. We measure the branching fractions B(B+ --> K0bar K+) = (1.61 +/- 0.44 +/- 0.09) * 10^-6 and B(B0 --> K0 K0bar) = (1.08 +/- 0.28 +/- 0.11) * 10^-6, and the CP-violating charge asymmetry A_{CP}(K0bar K+) = 0.10 +/- 0.26 +/- 0.03. Using a vertexing technique previously employed in several analyses of all-neutral final states containing kaons, we report the first measurement of time-dependent CP-violating asymmetries in B0 --> K0 K0bar, obtaining S = -1.28 +0.80/-0.73 +0.11/-0.16 and C = -0.40 +/- 0.41 +/- 0.06. We also report improved measurements of the branching fraction B(B0 --> K0 pi+) = (23.9 +/- 1.1 +/- 1.0) * 10^-6 and CP-violating charge asymmetry A_{CP}(K0 pi+) = -0.029 +/- 0.039 +/- 0.010.

    A graph G is called an (n,k)-graph if k(G- S) = n - |S| for any S C V(G) with |S| ≤ k,where k(G) denotes the connectivity of G. Mader conjectured that for k ≥ 3 the graph K2k+2-(1-factor) isthe unique (2k, k)-graph. Kriesell has settled two special cases for k = 3, 4. We prove the conjecture for thegeneral case k ≥ 5.

    Using $(106\\pm4)\\times 10^6$ $\\psip$ events accumulated with the BESIII detector at the BEPCII $e^+e^-$ collider, we present measurements of the branching fractions for psi' decays to $K^{+}K^{-}\\pi^{0}$ and $K^{+}K^{-}\\eta$. In these final states, the decay $\\psi'\\to K_2^{*}(1430)^+K^-+c.c.$ is observed for the first time, and its branching fraction is measured to be $(7.12\\pm{0.62}{\\rm (stat.)}^{+1.13}_{-0.61}{\\rm (syst.)})\\times 10^{-5}$, which indicates a violation of the helicity selection rule in $\\psip$ decays. The branching fractions of $\\psi'\\to K^*(892)^+K^-+c.c., \\phi\\eta, \\phi\\pi^0$ are also measured. The measurements are used to test the QCD predictions on charmonium decays.

  19. Vitamine K

    Full Text Available Subclasses of vitamin K, their origins, their differential characteristics of absorption and metabolism, their relative effects on gammacarboxylation of various proteins implicated in hemostasis andcoagulation, in bone calcification are not well known even by experts in these fields. These misunderstandings explain errors in recommendations for public and for patients. This review will not expose again the fundamentals on vitamins K as presented in the paper by Marc Guillaumont published in 2000 in this same journal. This 2011 review will try to update our actual knowledge and most of all will insist on their practical implications especially on the management of oral anticoagulant treatments since until recently vitamin K antagonist was the only available type of such a treatment. Several examples illustrate the need for a better understanding of this subject. The fear that diet vitamin K could deregulate the equilibrium of oral vitamin K antagonist treatment leads to recommend a quite total suppression of vitamin K containing components in the diet of anticoagulated patients. This leads to an opposite effect: a high sensitivity to vitamin K and to disequilibrium of the anticoagulant treatment while a comprehensivemoderate and regular diet intake of vitamin K first facilitates the food choice of the patients but also helps to stabilise the treatment of chronically anticoagulated patients. Vitamin K plays a role in bone calcification and in osteoporosis prevention. Until recently the food supplementation with vitamin K in view of preventing osteoporosis in general population was strongly limited due to fear to affect the treatment equilibrium in anticoagulated patients. While an understanding that the effects of moderate supplementation in vitamin K has no or limited effect on anticoagulation and on the long run could at the opposite help to stabilize the daily level of anticoagulation in patients chronically treated with vitamin K.

    Using 14M ψ (2 S) events taken with the BESII detector, χcJ → 2 (K+K-) decays are studied. For the four-kaon final state, the branching fractions are B (χc 0 , 1 , 2 → 2 (K+K-)) = (3.48 ± 0.23 ± 0.47) ×10-3, (0.70 ± 0.13 ± 0.10) ×10-3, and (2.17 ± 0.20 ± 0.31) ×10-3. For the ϕK+K- final state, the branching fractions, which are measured for the first time, are B (χc 0 , 1 , 2 → ϕK+K-) = (1.03 ± 0.22 ± 0.15) ×10-3, (0.46 ± 0.16 ± 0.06) ×10-3, and (1.67 ± 0.26 ± 0.24) ×10-4.

  1. Scalable K-Means++

    2012-01-01

    Over half a century old and showing no signs of aging, k-means remains one of the most popular data processing algorithms. As is well-known, a proper initialization of k-means is crucial for obtaining a good final solution. The recently proposed k-means++ initialization algorithm achieves this, obtaining an initial set of centers that is provably close to the optimum solution. A major downside of the k-means++ is its inherent sequential nature, which limits its applicability to massive data: one must make k passes over the data to find a good initial set of centers. In this work we show how to drastically reduce the number of passes needed to obtain, in parallel, a good initialization. This is unlike prevailing efforts on parallelizing k-means that have mostly focused on the post-initialization phases of k-means. We prove that our proposed initialization algorithm k-means|| obtains a nearly optimal solution after a logarithmic number of passes, and then show that in practice a constant number of passes suffic...

  4. K Basin safety analysis

    International Nuclear Information System (INIS)

    The purpose of this accident safety analysis is to document in detail, analyses whose results were reported in summary form in the K Basins Safety Analysis Report WHC-SD-SNF-SAR-001. The safety analysis addressed the potential for release of radioactive and non-radioactive hazardous material located in the K Basins and their supporting facilities. The safety analysis covers the hazards associated with normal K Basin fuel storage and handling operations, fuel encapsulation, sludge encapsulation, and canister clean-up and disposal. After a review of the Criticality Safety Evaluation of the K Basin activities, the following postulated events were evaluated: Crane failure and casks dropped into loadout pit; Design basis earthquake; Hypothetical loss of basin water accident analysis; Combustion of uranium fuel following dryout; Crane failure and cask dropped onto floor of transfer area; Spent ion exchange shipment for burial; Hydrogen deflagration in ion exchange modules and filters; Release of Chlorine; Power availability and reliability; and Ashfall

    Recently, it has been observed that when representations are learnt in a way that encourages sparsity, improved performance is obtained on classification tasks. These methods involve combinations of activation functions, sampling steps and different kinds of penalties. To investigate the effectiveness of sparsity by itself, we propose the k-sparse autoencoder, which is an autoencoder with linear activation function, where in hidden layers only the k highest activities are kept. When applied t...

    2011-01-01

    K-core inflation is a new class of underlying inflation measures. The two most popular measures of underlying inflation are core inflation and trimmed mean inflation. The former removes fixed categories of goods and services (food and energy) from the inflation calculation, and the latter removes fixed percentiles of the weighted distribution of price changes. In contrast, k-core inflation specifies a size of relative price change to be removed from the inflation calculation. Thus, the catego...

    We present the first clear observation of the doubly Cabibbo suppressed decay D+ --> K-K+K+ and the first observation of the singly Cabibbo suppressed decay Ds+ --> K-K+K+. These signals have been obtained by analyzing the high statistics sample of photoproduced charm particles of the FOCUS(E831) experiment at Fermilab. We measure the following relative branching ratios: Gamma(D+ --> K-K+K+)/Gamma(D+ --> K-pi+pi+) = (9.49 +/- 2.17(statistical) +/- 0.22(systematic))x10^-4 and Gamma(Ds+ --> K-K+K+)/Gamma(Ds+ --> K-K+pi+) = (8.95 +/- 2.12(statistical) +2.24(syst.) -2.31(syst.))x10^-3.

  16. Hypermodal Logics K[TnK]and K[TKn]%超模态逻辑K[TnK]和K[TKn

    2012-01-01

    The work of this paper is based on one paper of D. M. Gabbay, which is 'A theory of hypermodal logics: Mode shifting in modal logic'. Specially, based on his two satisfaction relations, I define n + 1 satisfaction relations, and then gain two kinds of more general logics K[TnK]and K[TKn], whereas n 〉 1. There we will get more general results: (1) For any n ≥ 1,口j+(n+l)kp→ 口i+(n+l)kp are theorems of K[TnK], whereas 0 ≤i 〈 j ≤ n. (2) For any n ≥1, every logic of IC[TKn] has theorems 口j+(n+l)kp→ 口i+(n+l)kp, whereas n 〉 1. However, 口j+(n+l)kp→ 口i+(n+l)kp are not theorems of IC[TK@ whereas 0 ≤i 〈 j ≤ n., and j ≠ 1, or i ≠0. So, (3) every logic of 1C[TnK] is a proper extension of logic K[TnK], for each n 〉 1. (4) The rule of Necessitation is not available to logics of IC[TnK] and K.[TKn], well, for any n ≥1, Yqn+lA is a theorem of K[TnK]and K[TKn], whereas A is a theorem of ICK[TnK]and K[TKn], respectively. (5) Logics of K[TnK]and K[TKn] are not closed under substitution of provably equivalent formulas. Besides, based on his two translations T0, T1 from hypermodal logic K[TK] to standard K, we define n + 1 translations TO, T1.....Tn from hypermodal logics K[TnK] and K[TKn] to standard K, respectively. Then we get a correspondence of pointed model satisfaction with logics IC[TnK], 1C[TKn] and standard K, respectively, i.e. a hypermodal formula is true in a world by some satisfaction relation iff the corresponding translation of the hypermodal formula is true in that world by the standard K satisfaction relation.%本文的工作是在D.M.Gabbay的一篇论文《超模态逻辑理论:在模态逻辑中的模转换》基础上所做的,主要是将他的两类满足关系扩充到n+1种满足关系,然后在此基础上得到两类一般性的逻辑类K[TnK]和K[TKn],其中n≥1。我们得到了一些更为一般性的结论:(1)逻辑类K[TnK]的定理模式是:对任意n≥1,口j+(n+1

    2015-01-01

    In this note, we describe a connection between the enumerative geometry of curves in K3 surfaces and the chiral ring of an auxiliary superconformal field theory. We consider the invariants calculated by Yau--Zaslow (capturing the Euler characters of the moduli spaces of D2-branes on curves of given genus), together with their refinements to carry additional quantum numbers by Katz--Klemm--Vafa (KKV), and Katz--Klemm--Pandharipande (KKP). We show that these invariants can be reproduced by studying the Ramond ground states of an auxiliary chiral superconformal field theory which has recently been observed to give rise to mock modular moonshine for a variety of sporadic simple groups that are subgroups of Conway's group. We also study equivariant versions of these invariants. A K3 sigma model is specified by a choice of 4-plane in the K3 D-brane charge lattice. Symmetries of K3 sigma models are naturally identified with 4-plane preserving subgroups of the Conway group, according to the work of Gaberdiel--Hoheneg...

    We analyze the decay B0 --> K+ K- K0 using 383 million B-Bbar events collected by the BaBar detector at SLAC to extract CP violation parameter values over the Dalitz plot. Combining all K+ K- K0 events, we find A_CP = -0.015 +/- 0.077 +/- 0.053 and beta_eff = 0.352 +/- 0.076 +/- 0.026 rad, corresponding to a CP violation significance of 4.8 sigma. A second solution near pi/2 - beta_eff is disfavored with a significance of 4.5 sigma. We also report A_CP and beta_eff separately for decays to phi(1020) K0, f0(980) K0, and K+ K- K0 with m_{K+ K-} > 1.1 GeV/c^2.

    Silarski, M

    2014-01-01

    In this article studies of the near threshold $pp\\to ppK^+K^-$ reaction conducted with the COSY-11 and the ANKE detectors are reviewed. In particular recent investigations on the $K^+K^-$ final state interaction are revisited taking into account updated cross sections of the COSY-11 experiment. These studies resulted in the new value of $K^+K^-$ effective range amounting to: $\\mathrm{Re}(b_{K^{+}K^{-}}) = -0.2^{+0.8_{stat}~+0.4_{sys}}_{-0.6_{stat}~-0.4_{sys}}~\\mathrm{fm}$ and $\\mathrm{Im}(b_{K^{+}K^{-}}) = 1.2^{~+0.5_{stat}~+0.3_{sys}}_{~-0.3_{stat}~-0.3_{sys}}~\\mathrm{fm}$. The determined real and imaginary parts of the $K^+K^-$ scattering length were estimated to be: $\\left|\\mathrm{Re}(a_{K^{+}K^{-}})\\right| = 10^{~+17_{stat}}_{~-10_{stat}}~\\mathrm{fm}$ and $\\mathrm{Im}(a_{K^{+}K^{-}}) = 0^{~+37_{stat}}_{~-10_{stat}}~\\mathrm{fm}$.

    We present the first search for the decay B0 --> K0_S K0_S K0_L using a data sample of 232 million B Bbar pairs. We find no statistically significant evidence for the non-resonant component of this decay. Our central value for the branching fraction, assuming the true Dalitz distribution is uniform and excluding the phi resonance, is B(B0 --> K0_S K0_S K0_L) = (2.4 +2.7 -2.5 +/- 0.6) x 10^{-6} where the errors are statistical and systematic, respectively. We set a single-sided Bayesian upper limit of B(B0 --> K0_S K0_S K0_L) K0_S K0_S K0_L) < 14 x 10^{-6}.

    The K+K+ scattering length is calculated in fully-dynamical lattice QCD with domain-wall valence quarks on the MILC asqtad-improved gauge configurations with rooted staggered sea quarks. Three-flavor mixed-action chiral perturbation theory at next-to-leading order, which includes the leading effects of the finite lattice spacing, is used to extrapolate the results of the lattice calculation to the physical value of m_{K+}/f_{K+}. We find m_{K+} a_{K+K+} = -0.352 +- 0.016, where the statistical and systematic errors have been combined in quadrature.

    The observation of hydrogenlike π K atoms, consisting of π-K+ or π+K- mesons, is presented. The atoms are produced by 24 GeV /c protons from the CERN PS accelerator, interacting with platinum or nickel foil targets. The breakup (ionization) of π K atoms in the same targets yields characteristic π K pairs, called "atomic pairs," with small relative momenta Q in the pair center-of-mass system. The upgraded DIRAC experiment observed 349 ±62 such atomic π K pairs, corresponding to a signal of 5.6 standard deviations. This is the first statistically significant observation of the strange dimesonic π K atom.

  5. T2K & beyond

    Catanesi, M G

    2016-01-01

    This article presents the status of the art of the T2K experiment and the measurements prospects for the incoming years. After a brief description of the experiment, the most recent results will be illustrated. The observation of the electron neutrino appearance in a muon neutrino beam and the new high-precision measurements of the mixing angle theta13 by the reactor experiments have led to a re-evaluation of the expected sensitivity to the oscillation parameters, relative to what was given in the original T2K proposal. For this reason the new physics potential of T2K for 7.8 x 10**21 p.o.t. and for a data exposure 3 times larger than it's expected to be reachable with accelerator and beam line upgrades in 2026 before the start of operation of the next generation of long-baseline neutrino oscillation experiments will also be described in the text. In particular the last challenging scenario opens the door to the possibility to obtain, under some conditions, a 3 sigma measurement excluding sin(deltaCP= 0.

  6. Penguin amplitudes in B^+ to pi^+ K^*0, K^+ \\bar{K}^*0 decays

    The question of the relative size of two independent penguin amplitudes is studied using the data on the B^+ to pi^+ K^*0, and B^+ to K^+ \\bar{K}^*0 decays. Our discussion involves a Regge-phenomenology-based estimate of SU(3) breaking in the final quark-pair-creating hadronization process. The results are in agreement with earlier estimates of the relative size of the two penguins obtained from B^+ to pi^+ K^0, K^+ \\bar{K}^0.

    We study the processes e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}-{gamma}, K{sup +}K{sup -}{pi}{sup 0}{pi}{sup 0}{gamma}, and K{sup +}K{sup -}K{sup +}K{sup -}{gamma}, where the photon is radiated from the initial state. About 84000, 8000, and 4200 fully reconstructed events, respectively, are selected from 454 fb{sup -1} of BABAR data. The invariant mass of the hadronic final state defines the e{sup +}e{sup -} center-of-mass energy, so that the K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{gamma} data can be compared with direct measurements of the e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}{sup -} reaction. No direct measurements exist for the e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup 0}{pi}{sup 0} or e{sup +}e{sup -} {yields} K{sup +}K{sup -}K{sup +}K{sup -} reactions, and we present an update of our previous result with doubled statistics. Studying the structure of these events, we find contributions from a number of intermediate states, and extract their cross sections. In particular, we perform a more detailed study of the e{sup +}e{sup -} {yields} {phi}(1020){pi}{pi}{gamma} reaction, and confirm the presence of the Y (2175) resonance in the {phi}(1020)f{sub 0}(980) and K{sup +}K{sup -} f{sub 0}(980) modes. In the charmonium region, we observe the J/{psi} in all three final states and in several intermediate states, as well as the {phi}(2S) in some modes, and measure the corresponding branching fractions.

    Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement of the branching ratio for the Cabibbo-favored decay mode $D^0 \\to K^-K^-K^+\\pi^+$. From a sample of $143 \\pm 19$ fully reconstructed $D^0 \\to K^-K^-K^+\\pi^+$ events, we measure $\\Gamma(D^0 \\to K^-K^-K^+\\pi^+)/\\Gamma(D^0 \\to K^-\\pi^-\\pi^+\\pi^+) = 0.00257 \\pm 0.00034(stat.) \\pm 0.00024(syst.)$. A coherent amplitude analysis has been performed to determine the resonant substructure of this decay mode. This analysis reveals a dominant contribution from $\\phi$ and $\\bar K^{*0}(890)$ states.

  10. Dalitz plot analysis of the $D^+ \\rightarrow K^- K^+ K^+$ decay with the isobar model

    2016-01-01

    This note presents a study of the $K^-K^+$ S-wave amplitude in doubly Cabibbo-suppressed ${D^+ \\rightarrow K^- K^+ K^+}$ decays performed using $2 \\text{fb}^{-1}$ of data collected by the LHCb detector in $pp$ collisions at $8~\\text{TeV}$ centre-of-mass energy. The Dalitz plot is studied under the assumption of the isobar model for resonance scattering. Models with combinations of resonant states are tested. Fits of comparable quality are obtained for different $K^-K^+$ S-wave parameterizations. The results obtained indicate that a variation of the S-wave phase at both ends of $K^-K^+$ spectrum is needed to describe the data. Further studies beyond the näive isobar model are foreseen to understand the $K^-K^+$ S-wave.

  12. k-Inflation

    Armendariz-Picon, C; Mukhanov, V

    1999-01-01

    It is shown that a large class of higher-order (i.e. non-quadratic) scalar kinetic terms can, without the help of potential terms, drive an inflationary evolution starting from rather generic initial conditions. In many models, this kinetically driven inflation (or "k-inflation" for short) rolls slowly from a high-curvature initial phase, down to a low-curvature phase and can exit inflation to end up being radiation-dominated, in a naturally graceful manner. We hope that this novel inflation mechanism might be useful in suggesting new ways of reconciling the string dilaton with inflation.

About 34600, 4400 and 2300 fully reconstructed events respectively, are selected from 232 fb{sup -1} of BABAR data. The invariant mass of the hadronic final state defines the effective e{sup +}e{sup -} center-of-mass energy, so that the K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{gamma} data can be compared with direct measurements of the e{sup +}e{sup -} {yields} K{sup +}K{sup -}{pi}{sup +}{pi}{sup -}{gamma} reaction; no direct measurements exist for the e{sub +}e{sub -} {yields} K{sup +}K{sup -}{pi}{sup 0}{pi}{sup 0}{gamma} or e{sub +}e{sub -} {yields} K{sup +}K{sup -}K{sup +}K{sup -} reactions.

In particular, we isolate the contribution from e{sup +}e{sup -} {yields} {phi}(1020)f{sub 0}(980) and study its structure near threshold. In the charmonium region, we observe the J/{psi} in all three final states and several intermediate states, as well as the {psi}/(2S) in some modes, and measure the corresponding branching fractions.

    The observation of hydrogen-like $\\pi K$ atoms, consisting of $\\pi^- K^+$ or $\\pi^+ K^-$ mesons, is presented. The atoms have been produced by 24 GeV/$c$ protons from the CERN PS accelerator, interacting with platinum or nickel foil targets. The breakup (ionisation) of $\\pi K$ atoms in the same targets yields characteristic $\\pi K$ pairs, called ``atomic pairs'', with small relative momenta in the pair centre-of-mass system. The upgraded DIRAC experiment has observed $349\\pm62$ such atomic $\\pi K$ pairs, corresponding to a signal of 5.6 standard deviations.

    We present studies of the e+ e- --> K+ K- gamma reaction for the e+e- center-of-mass energies close to the phi(1020) meson mass. Different mechanisms leading to the final state are considered. The strong interaction amplitudes of the K+K- pairs in the S-wave are taken into account. In addition, the photon emission in the initial state, the final state radiation effects and all the possible interference terms are included in the transition matrix elements. The K+K- effective mass distributions and the angular dependence of the reaction cross-section are calculated.

    Full Text Available I denne artikkelen beskriver vi prinsipper for å utføre systematiske søk etter forskningslitteratur. I et godt søk bør det tas utgangspunkt i et klart formulert spørsmål som uttrykker hva slags forskning en ønsker å finne. For effektspørsmål kan dette formuleres ved hjelp av et PICO-skjema hvor det konkretiseres hvilke pasienter, tiltak og utfallsmål en er interessert i. I litteratursøket er det vanlig å bruke engelske søkeord som beskriver disse PICO-kategoriene. For å finne så mye relevant forskning som mulig, er det viktig å søke på alle relevante synonymer og staveformer. En kan også søke på standardiserte emneord som beskriver innholdet i publikasjonene. De boolske operatorene AND og OR brukes for å kombinere søkeordene i en samlet søkestrategi. For å få et håndterlig antall søketreff, kan søket avgrenses til publikasjonsår, spesielle aldersgrupper eller relevant studiedesign. Det kan være nyttig å dokumentere hvilke kilder og søkeord som er brukt. I de fleste kilder kan søket lagres og hentes frem senere og søkeresultatene kan eksporteres til referansehåndteringsprogrammer som Reference Manager eller EndNote. I noen tilfeller kan det være nyttig å supplere det systematiske søket med andre gjenfinningsmetoder som søk i studieregistre, gjennomgang av referanselister i relevante publikasjoner, siteringssøk og tips fra fageksperter. Litteratursøk er en ferdighet som læres ved praktisk øvelse og vi anbefaler alle å ta kontakt med en bibliotekar for å lære mer om dette.Kirkehei I, Ormstad SS. Searching for literature.

    The initial clinical trials for treatment of acute myeloid leukemia have demonstrated the effectiveness of the alpha emitter (213)Bi in killing cancer cells. Bismuth-213 is obtained from a radionuclide generator system from decay of 10-days (225)Ac parent. Recent pre-clinical studies have also shown the potential application of both (213)Bi, and the (225)Ac parent radionuclide in a variety of cancer systems and targeted radiotherapy. This paper describes our five years of experience in production of (225)Ac in partial support of the on-going clinical trials. A four-step chemical process, consisting of both anion and cation exchange chromatography, is utilized for routine separation of carrier-free (225)Ac from a mixture of (228)Th, (229)Th and (232)Th. The separation of Ra and Ac from Th is achieved using the marcoporous anion exchange resin MP1 in 8M HNO(3) media. Two sequential MP1/NO(3) columns provide a separation factor of approximately 10(6) for Ra and Ac from Th. The separation of Ac from Ra is accomplished on a low cross-linking cation exchange resin AG50-X4 using 1.2M HNO(3) as eluant. Two sequential AG50/NO(3) columns provide a separation factor of approximately 10(2) for Ac from Ra. A 60-day processing schedule has been adopted in order to reduce the processing cost and to provide the highest levels of (225)Ac possible. Over an 8-week campaign, a total of approximately 100 mCi of (225)Ac (approximately 80% of the theoretical yield) is shipped in 5-6 batches, with the first batch typically consisting of approximately 50 mCi. After the initial separation and purification of Ac, the Ra pool is re-processed on a bi-weekly schedule or as needed to provide smaller batches of (225)Ac. The averaged radioisotopic purity of the (225)Ac was 99.6 +/- 0.7% with a (225)Ra content of < or =0.6%, and an average (229)Th content of (4(-4)(+5)) x 10(-5)%.

    @@ In-medium effects and neutrino trapping on K+ and K- production and K- condensation in supernova matter are investigated in a chiral hadronic model. Our results show that neutrino trapping shifts the critical density for K- condensation to higher density, the Q values for K+ and K- production are not sensitive to neutrino trapping, in-medium effects decrease the Q values for NN → NNK+ K- and ∧N → NNK- and increase those for NN → N∧K+, K-p →∧π0 and K-n →∧π- as the density of supernova matter increases. Moreover,it is shown that neutrino trapping decreases the maximum masses of protoneutron stars compared with the neutrino-free case.

    The definition of k-dominating fuzzy matrices has been introduced. The relation between k-dominating fuzzy matrices and circularly k-dominating fuzzy matrices is discussed. We point out that the convergence or oscillating index of the power sequence of an n × n k-dominating matrix is bounded by (n-1)k+m from above; and if it is oscillating, then the period index is a factor of k.%给出k-控制阵的定义,讨论k-控制阵与k-圈控制阵的关系,指出k-控制阵的周期是k的一个因子,指数不大于(n-1)k+m.

    A Κ1,k-factorization of λΚm,n is a set of edge-disjoint Κl,k-factors of λΚm,n, which partition the set of edges of λΚm,n. In this paper, it is proved that a sufficient condition for the existence of Κ1,k-factorization of λΚm,n, whenever k is any positive integer, is that (1) m ≤ kn, (2) n ≤ kin, (3) km-n≡kn-m ≡ 0 (mood (k2-1)) and (4) λ(km-n)(kn-m) ≡0 (mod k(k-1)(k2 - 1)(m + n)).

    We investigate the decay of $f_1(1285) \\to \\pi K \\bar K$ with the assumption that the $f_1(1285)$ is dynamically generated from the $K^* \\bar{K} - cc$ interaction. In addition to the tree level diagrams that proceed via $f_1(1285) \\to K^* \\bar{K} - cc \\to \\pi K \\bar K$, we take into account also the final state interactions of $K \\bar K \\to K \\bar K$ and $\\pi K \\to \\pi K$. The partial decay width and mass distributions of $f_1(1285) \\to \\pi K \\bar K$ are evaluated. We get a value for the part...

    We search for B+/- --> [K^-/+ pi+/-]_D K+/- decays, where [K-/+ pi+/-]_D indicates that the K-/+ pi+/- pair originates from the decay of a D0 or D0bar. Results are based on 120 million Upsilon(4S) --> B Bbar decays collected with the BaBar detector at SLAC. We set an upper limit on the ratio R_Kpi = {Gamma(B+ --> [K- pi+]_D K+) + Gamma(B- --> [K+ pi-]_D K-)}/ {Gamma(B+ --> [K+ pi-]_D K+) + Gamma(B- --> [K- pi+]_D K-)} D0bar K-)/A(B- --> D0 K-)| D K will be difficult.

    We report the observation of the b -> d penguin-dominated decay B0 -> K*0 K*0bar with a sample of 383.2 +/- 4.2 million BBbar pairs collected with the BaBar detector at the PEP-II asymmetric-energy e^+e^- collider at the Stanford Linear Accelerator Center. The measured branching fraction is Br(B0 -> K*0 K*0bar) = [0.49^{+0.16}_{-0.13} +/- 0.05] x 10^{-6} and the fraction of longitudinal polarization f_L (B0 -> K*0 K*0bar) = 0.81^{+0.10}_{-0.12} +/- 0.06. The first error quoted is statistical and the second systematic. We also obtain an upper limit at the 90% confidence level on the branching fraction for Br(B0 ->K*0 K*0) < 0.18 x 10^{-6}.

    2016-01-01

    The observation of hydrogen-like $\\pi K$ atoms, consisting of $\\pi^- K^+$ or $\\pi^+ K^-$ mesons, is presented. The atoms have been produced by 24 GeV/$c$ protons from the CERN PS accelerator, interacting with platinum or nickel foil targets. The breakup (ionisation) of $\\pi K$ atoms in the same targets yields characteristic $\\pi K$ pairs, called "atomic pairs", with small relative momenta in the pair centre-of-mass system. The upgraded DIRAC experiment has observed $349\\pm62$ such atomic $\\pi...

  7. B -> rho K and B -> pi K^* decays in SCET

    2011-01-01

    Exploring hints of New Physics in the decay modes B -> pi K^* and B -> rho K can shed light on the B -> K pi puzzle. In this talk we discuss supersymmetric contributions to the direct CP asymmetries of the decays B -> pi K^* and B -> rho K within Soft Collinear Effective Theory. We consider non-minimal flavor SUSY contributions mediated by gluino exchange and apply the Mass Insertion Approximation in the analysis. We show that gluino contributions can enhance the CP asymmetries and accommodat...

  8. Generalised morphisms of k-graphs: k-morphs

    OpenAIRE

    Kumjian, Alex; Pask, David; Sims, Aidan

    2007-01-01

    In a number of recent papers, (k+l)-graphs have been constructed from k-graphs by inserting new edges in the last l dimensions. These constructions have been motivated by C*-algebraic considerations, so they have not been treated systematically at the level of higher-rank graphs themselves. Here we introduce k-morphs, which provide a systematic unifying framework for these various constructions. We think of k-morphs as the analogue, at the level of k-graphs, of C*-correspondences between C*-a...

    We present a study of the dynamics in B0 --> K+ K- K0S decays with approximately 230 million BBbar events collected by the BABAR detector at SLAC. We find that the Dalitz plot distribution is best parameterized with the phi K0S mode, an S-wave K+ K- resonance near 1500 MeV/c^2, and a large non-resonant contribution. We set limits on resonances not included in our model, and study models for the non-resonant contribution.

    International Nuclear Information System (INIS)

    After a description of three distinguished bases proposed for k-Poincare algebra, the representations of the k-deformed Poincare algebra as differential operators acting on the functions of commuting moments are considered. Further, the duality between the k-Poincare algebra Un(P4) and the quantum Poincare group Pk is discussed. The recent developments of the k-deformed formalism are presented in conclusion. 51 refs

    The observation of hydrogenlike πK atoms, consisting of π^{-}K^{+} or π^{+}K^{-} mesons, is presented. The atoms are produced by 24  GeV/c protons from the CERN PS accelerator, interacting with platinum or nickel foil targets. The breakup (ionization) of πK atoms in the same targets yields characteristic πK pairs, called "atomic pairs," with small relative momenta Q in the pair center-of-mass system. The upgraded DIRAC experiment observed 349±62 such atomic πK pairs, corresponding to a signal of 5.6 standard deviations. This is the first statistically significant observation of the strange dimesonic πK atom.

    We study contributions to the nucleon strange quark vector current form factors from intermediate states containing K^* mesons. We show how these contributions may be comparable in magnitude to those made by K mesons, using methods complementary to those employed in quark model studies. We also analyze the degree of theoretical uncertainty associated with K^* contributions.

    In the present work we use the idea of the K-groups to define the K-Kolmogorov homology groups, and their induced homomorphisms and boundary operators for the case of a pair of discrete coefficient groups, where K denotes a locally-finite simplicial complex. Moreover, we prove that our homology construction is exact. (author)

    Motivated by recent Belle measurement of the branching ratios $B^- \\to \\pi^+ \\pi^- K^-$ and $B^- \\to K^+ K^- K^-$ and $B^\\pm \\to \\chi_{c0} K^\\pm$, we investigate the CP violating asymmetry in the partial widths for the decays $B^- \\to \\pi^+ \\pi^- K^-$ and $B^- \\to K^+ K^- K^-$, which results from the interference of the nonresonant decay amplitude with the resonant amplitude $B^\\pm \\to \\chi_{c0} K^\\pm $ $ \\to\\pi^+ \\pi^- K^\\pm $ and $B^\\pm \\to \\chi_{c0} K^\\pm$ $ \\to K^+ K^- K^-$.

    Full Text Available Članek prinaša premisleke o vstajniških praksah, o »kulturi upora«, ki je konec leta 2012 zajela slovenski prostor. Poudarjena sta dva sklopa: vpetost lokalnih manifestacij vstajništva v globalne matrice uporov, kar je tematizirano skozi akcije solidarnosti in mreženja s turškimi aktivisti, večinoma študentov v Ljubljani (primer aktivacije s pomočjo skupnosti »Occupy Gezi – Ljubljana«, in vsebinski poudarki in izostanki, to so centralizirane osrednje vsebine vstaj in obrobnejši upori, kakršna sta bila »Protest iz obupa« in solidariziranje z mariborskimi livarji. Nove kristalizacijske točke uporov se bodo verjetno odvijale na področju socialnih in delavskih pravic, ki so osrednje »novo« bojišče družbenih neenakosti, revščine in preživetja. »Nazaj k uporu!« kliče novodobni prekerni delavec, ki lahko kadarkoli izgubi službo, stanovanje, socialno zavarovanje.

    Branching fraction and asymmetry measurements of charmless $B^0\\to K^{*0}h^+_1h^-_2$ ($h_{1,2}$ = $K$, $\\pi$) decays are presented, using a data sample of 383 million $\\Upsilon(4S) \\to$ $B\\bar{B$} decays collected with the BaBar detector at the PEP-II asymmetric-energy $B$-meson factory at SLAC. The results are: ${\\cal B}$($B^0 \\to K^{*0}K^+ K^-)$ = (27.5 $\\pm$ 1.3 $\\pm$ 2.2) $\\times$ 10$^{-6}$, ${\\cal B}$($B^0$ $\\to$ $K^{*0}\\pi^+ K^-$) = (4.6 $\\pm$ 1.1 $\\pm$ 0.8) $\\times$ 10$^{-6}$ and ${\\cal B}$($B^0$ $\\to$ $K^{*0}\\pi^+\\pi^-$) = (54.5 $\\pm$ 2.9 $\\pm$ 4.3) $\\times$ 10$^{-6}$. The first errors quoted are statistical and the second are systematic. An upper limit is set for ${\\cal B}$($B^0$ $\\to$ $K^{*0}K^+ \\pi^-$) $<$ 2.2 $\\times$ 10$^{-6}$ at 90% confidence level.

  2. Vitamin K and bone health.

    Science.gov (United States)

    2013-01-01

    Vitamin K has been purported to play an important role in bone health. It is required for the gamma-carboxylation of osteocalcin (the most abundant noncollagenous protein in bone), making osteocalcin functional. There are 2 main forms (vitamin K1 and vitamin K2), and they come from different sources and have different biological activities. Epidemiologic studies suggest a diet high in vitamin K is associated with a lower risk of hip fractures in aging men and women. However, randomized controlled trials of vitamin K1 or K2 supplementation in white populations did not increase bone mineral density at major skeletal sites. Supplementation with vitamin K1 and K2 may reduce the risk of fractures, but the trials that examined fractures as an outcome have methodological limitations. Large well-designed trials are needed to compare the efficacies of vitamin K1 and K2 on fractures. We conclude that currently there is not enough evidence to recommend the routine use of vitamin K supplements for the prevention of osteoporosis and fractures in postmenopausal women.

    The authors present the first search for the decay B{sup 0} {yields} K{sub S}{sup 0} K{sub S}{sup 0} K{sub L}{sup 0} using a data sample of 232 million B{bar B} pairs. They find no statistically significant evidence for the non-resonant component of this decay. Our central value for the branching fraction, assuming the tru Dalitz distribution is uniform and excluding the {phi} resonance, is {Beta}(B{sup 0} {yields} K{sub S}{sup 0} K{sub S}{sup 0} K{sub L}{sup 0}) = (2.4{sub -2.5}{sup +2.7} {+-} 0.6) x 10{sup -6} where the errors are statistical and systematic, respectively. They set a single-side Bayesian upper limit of {Beta}(B{sup 0} {yields} K{sub S}{sup 0} K{sub S}{sup 0} K{sub L}{sup 0}) < 6.4 x 10{sup -6} at 90% confidence level using a uniform prior probability for physical values. Assuming the worst-case true Dalitz distribution, where the signal is entirely in the region of lowest efficiency, the 90% confidence level upper limit is {Beta}(B{sup 0} {yields} K{sub S}{sup 0} K{sub S}{sup 0} K{sub L}{sup 0}) < 14 x 10{sup -6}.

    We report the observation of charmless hadronic decays of charged B mesons to the final state K+K-pi+. Using a data sample of 347.5 fb^-1 collected at the Y(4S) resonance with the BABAR detector, we observe 429+/-43 signal events with a significance of 9.6 sigma. We measure the inclusive branching fraction BF(B+ --> K+K-pi+) = [5.0+/-0.5(stat.)+/-0.5(syst.)]x10^-6. Inspection of the Dalitz plot of signal candidates shows a broad structure peaking near 1.5 GeV/c^2 in the K+K- invariant mass distribution. We find the direct CP asymmetry to be consistent with zero.

  5. Photoproduction of the K+ K0-(1750)

    Energy Technology Data Exchange (ETDEWEB)

    Mitchell, Ryan Edward

    2003-01-01

    While photoproduction has often been advertised as an important environment in which to study light meson spectroscopy, solid experimental results are sparse. In fact, beyond the relatively straightforward photoproduction of the {rho}, {omega}, and {phi} mesons, the few results of exclusive photoproduction that do exist are poorly understood, and several, perhaps, have even been misinterpreted. After extensively reviewing the sometimes tenuous history of the exclusive photoproduction of the ''{rho}{sup 1}(1600)'', the ''{omega}{pi}{sup 0}(1250)'', the ''{omega}(1650)'', and the ''K{sup +}K{sup -}(1750)'', new results from the E831/FOCUS photoproduction experiment at Fermilab are presented which address the interpretation of the K{sup +}K{sup -}(1750). This enhancement in low-p{sub T} K{sup +}K{sup -} pairs at a mass near 1750 MeV/c{sup 2} has been observed by several previous photoproduction experiments, but, despite several apparent inconsistencies, it has always been interpreted as the J{sup PC} = 1{sup --} {phi}(1680) meson. With nearly two orders of magnitude more events than any previous observation of the K{sup +}K{sup -}(1750), and based on precise measurements of its mass and width, and its absence from the K*K final state, the FOCUS data can finally render this interpretation implausible. In addition, several steps have been taken towards establishing a new interpretation. Based on limited angular analyses of its decay and the beam energy dependence of its production, they argue that, in the absence of any wild interference scenarios, the K{sup +}K{sup -}(1750) has J{sup PC} {ne} 1{sup --}, and, in fact, the most likely assignment appears to be 2{sup ++}. It is hoped that this work can help set the stage for future reevaluations and new insights in photoproduction.

    The first flavor-tagged amplitude analysis of the decay D0 to the self-conjugate final state K+K-pi+pi- is presented. Data from the CLEO II.V, CLEO III, and CLEO-c detectors are used, from which around 3000 signal decays are selected. The three most significant amplitudes, which contribute to the model that best fits the data, are phirho0, K1(1270)+-K-+, and non-resonant K+K-pi+pi-. Separate amplitude analyses of D0 and D0-bar candidates indicate no CP violation among the amplitudes at the level of 5% to 30% depending on the mode. In addition, the sensitivity to the CP-violating parameter gamma/phi3 of a sample of 2000 B+ -> D0-tilde(K+K-pi+pi-)K+ decays, where D0-tilde is a D0 or D0-bar, collected at LHCb or a future flavor facility, is estimated to be (11.3 +/- 0.3) degrees using the favored model.

  9. Parabolic k-ample bundles

    Biswas, Indranil

    2011-01-01

    We construct projectivization of a parabolic vector bundle and a tautological line bundle over it. It is shown that a parabolic vector bundle is ample if and only if the tautological line bundle is ample. This allows us to generalize the notion of a k-ample bundle, introduced by Sommese, to the context of parabolic bundles. A parabolic vector bundle $E_*$ is defined to be k-ample if the tautological line bundle ${\\mathcal O}_{{\\mathbb P}(E_*)}(1)$ is $k$--ample. We establish some properties of parabolic k-ample bundles.

  11. $K^+$-nucleus potentials from $K^+$-nucleon amplitudes

    Friedman, E

    2016-01-01

    Optical potentials for $K^+$-nucleus interactions are constructed from $K^+$-nucleon amplitudes using recently developed algorithm based on $K^+$-N kinematics in the nuclear medium. With the deep penetration of $K^+$ mesons into the nucleus at momenta below 800~MeV/c it is possible to test this approach with greater sensitivity than hitherto done with $K^-$ and pions. The energy-dependence of experimental reaction and total cross sections on nuclei is better reproduced with this approach compared to fixed-energy amplitudes. The inclusion of Pauli correlations in the medium also improves the agreement between calculation and experiment. The absolute scale of the cross sections is reproduced very well for $^6$Li but for C, Si and Ca calculated cross sections are (23$\\pm4$)\\% smaller than experiment, in agreement with earlier analyses. Two phenomenological models that produce such missing strength suggest that the imaginary part of the potential needs about 40\\% enhancement.

    Optical potentials for K+-nucleus interactions are constructed from K+-nucleon amplitudes using recently developed algorithm based on K+-N kinematics in the nuclear medium. With the deep penetration of K+ mesons into the nucleus at momenta below 800 MeV / c it is possible to test this approach with greater sensitivity than hitherto done with K- and pions. The energy-dependence of experimental reaction and total cross sections on nuclei is better reproduced with this approach compared to fixed-energy amplitudes. The inclusion of Pauli correlations in the medium also improves the agreement between calculation and experiment. The absolute scale of the cross sections is reproduced very well for 6Li but for C, Si and Ca calculated cross sections are (23 ± 4)% smaller than experiment, in agreement with earlier analyses. Two phenomenological models that produce such missing strength suggest that the imaginary part of the potential needs about 40% enhancement.

    We perform amplitude analyses of the decays B{sup 0} {yields} K{sup +}K{sup -}K{sub s}{sup 0}, B{sup +} {yields} K{sup +}K{sup -}K{sup +}, and B{sup +} {yields}, and measure CP-violating parameters and partial branching fractions. The results are based on a data sample of approximately 470 x 10{sup 6} B{bar B} decays, collected with the BABAR detector at the PEP-II asymmetric-energy B factory at the SLAC National Accelerator Laboratory. For B{sup +} {yields} K{sup +}K{sup -}K{sup +}, we find a direct CP asymmetry in B{sup +} {yields} {phi}(1020)K{sup +} of A{sub CP} = (12.8 {+-} 4.4 {+-} 1.3)%, which differs from zero by 2.8{sigma}. For B{sup 0} {yields} K{sup +}K{sup -}K{sub s}{sup 0}, we measure the CP-violating phase {beta}{sub eff} ({phi}(1020)K{sub s}{sup 0}) = (21 {+-} 6 {+-} 2){sup o}. For B{sup +} {yields} K{sub s}{sup 0}K{sub s}{sup 0}K{sup +}, we measure an overall direct CP asymmetry of A{sub CP} = (4{sub -5}{sup +4} {+-} 2)%. We also perform an angular-moment analysis of the three channels, and determine that the f{sub X}(1500) state can be described well by the sum of the resonances f{sub 0}(1500), f{prime}{sub 2}(1525), and f{sub 0}(1710).

    The authors report a search for the decays B{sup -} {yields} K{sup +}{pi}{sup -}{pi}{sup -} and B{sup -} {yields} K{sup -}K{sup -}{pi}{sup +}, which are highly suppressed in the Standard Model. Using a sample of (467 {+-} 5) x 10{sup 6} B{bar B} pairs collected with the BABAR detector, they do not see any evidence of these decays and determine 90% confidence level upper limits of {Beta}(B{sup -} {yields} K{sup +}{pi}{sup -}{pi}{sup -}) < 9.5 x 10{sup -7} and {Beta}(B{sup -} {yields} K{sup -}K{sup -}{pi}{sup +}) < 1.6 x 10{sup -7} on the corresponding branching fractions, including systematic uncertainties.

    Results from the first PWA of the K +K - system produced by incident K -, are presented in the mass range from the threshold to 1.70 GeV. In the P and D waves only the φ and f' mesons are observed and their production mechanism studied. A broad S wave peaking at 1.4 GeV is observed but the lack of information about its phase makes the search for new 0 ++ mesons inconclusive.

    Recent results from solar, reactor, atmospheric and long baseline (K2K) experiments are discussed. With the improved data statistics and analyses, our knowledge on the neutrino masses and mixing angles are steadily improving. T2K is the next generation neutrino oscillation experiment between J-PARC in Tokai and Super-Kamiokande. This experiment will start in 2009. This experiment is expected to improve the current knowledge on the neutrino masses and mixings substantially.

    A Dalitz plot analysis of approximately 12,500 D{sup 0} events reconstructed in the hadronic decay D{sup 0} {yields} {bar K}{sup 0} K{sup +}K{sup -} is presented. This analysis is based on a data sample of 91.5 fb{sup -1} collected with the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} storage rings at SLAC running at center-of-mass energies on and 40 MeV below the {Upsilon}(4S) resonance. The events are selected from e{sup +}e{sup -} {yields} c{bar c} annihilations using the decay D*{sup +} {yields} D{sup 0}{pi}{sup +}. The following ratio of branching fractions has been obtained: BR = {Lambda}(D{sup 0} {yields} {bar K}{sup 0}K{sup +}K{sup -})/{Lambda}(D{sup 0} {yields} {bar K}{sup 0}{pi}{sup +}{pi}{sup -}) = (15.8 {+-} 0.1(stat.) {+-} 0.5 (syst.)) x 10{sup -2}. Estimates of fractions and phases for resonant and non-resonant contributions to the Dalitz plot are also presented. The a{sub 0}(980) {yields} {bar K}K projection has been extracted with little background. A search for Cp asymmetries on the Dalitz plot has been performed.

    Coupled-channel $\\pi K$ and $\\eta K$ scattering amplitudes are determined by studying the finite-volume energy spectra obtained from dynamical lattice QCD calculations. Using a large basis of interpolating operators, including both those resembling a $q\\bar{q}$ construction and those resembling a pair of mesons with relative momentum, a reliable excited-state spectrum can be obtained. Working at ${m_\\pi=391\\,\\mathrm{MeV}}$, we find a gradual increase in the $J^P=0^+$ $\\pi K$ phase-shift which...

This analysis is based on a data sample of 91.5 fb-1 collected with the BaBar detector at the PEP-II asymmetric-energy e+ e- storage rings at SLAC running at center-of-mass energies on and 40 MeV below the Y4S resonance. The events are selected from e+ e- --> c cbar annihilations using the decay D*+ --> D0 pi+. The following ratio of branching fractions has been obtained: BR = Gamma(D0-->K0bar K+ K-)/Gamma(D0-->K0bar pi+ pi-) = (15.8+/-0.1(stat.)+/-0.5(syst.)x 10-2 Estimates of fractions and phases for resonant and non-resonant contributions to the Dalitz plot are also presented. The a0(980)-->K Kbar projection has been extracted with little background. A search for CP asymmetries on the Dalitz plot has been performed.

    k2photometry reads, reduces and detrends K2 photometry and searches for transiting planets. MAST database pixel files are used as input; the output includes raw lightcurves, detrended lightcurves and a transit search can be performed as well. Stellar variability is not typically well-preserved but parameters can be tweaked to change that. The BLS algorithm used to detect periodic events is a Python implementation by Ruth Angus and Dan Foreman-Mackey (https://github.com/dfm/python-bls).

    Hammer, H. -W.; Ramsey-Musolf, M. J.

    1999-01-01

    We analyse the isoscalar vector current form factors of the nucleon using dispersion relations. In addition to the usual vector meson poles, we account for the K\\bar{K}-continuum contribution by drawing upon a recent analytic continuation of KN scattering amplitudes. For the Pauli form factor all strength in the \\phi region is already given by the continuum contribution, whereas for the Dirac form factor additional strength in the \\phi region is required. The pertinent implications for the le...

    This paper reports measurements of processes: e+e- -> gamma KsK+pi-, e+e- -> gamma K+K-pi0, e+e- -> gamma phi eta, and e+e- -> gamma phi pi0. The initial state radiated photon allows to cover the hadronic final state in the energy range from thresholds up to ~4.6 GeV. The overall size of the data sample analyzed is 232 fb-1, collected by the BaBar detector running at the PEP-II e+e- storage ring. From the Dalitz plot analysis of the KsK+pi- final state, moduli and relative phase of the isoscalar and the isovector components of the e+e- -> K K*(892) cross section are determined. Parameters of phi and rho recurrences are also measured, using a global fitting procedure which exploits the interconnection among amplitudes, moduli and phases of the e+e- -> KsK+pi-, K+K-pi0, phi eta final states. The cross section for the OZI-forbidden process e+e- -> phi pi0, and the J/psi branching fractions to KK*(892) and K+K-eta are also measured.

    International Nuclear Information System (INIS)

    High-spin states in 43K were studied using the 9Be(36S,pnγ)43K reaction. Threefold (pγ1γ2) coincidence data and γ-ray intensity ratios were used to establish a decay scheme and identify negative- and positive-parity yrast decay chains. The 15/2- yrast state is relatively poorly aligned prior to decay. Energies of positive-parity levels predicted by Johnstone are in good agreement with experiment

    We analyze the three-body charmless decay B+- -> K+-K+-K-+ using a sample of 226.0 +- 2.5 million BBbar pairs collected by the BABAR detector. We measure the total branching fraction and CP asymmetry to be B = (35.2 +- 0.9 +-1.6) x 10^{-6} and A_CP = (-1.7 +- 2.6 +- 1.5)%. We fit the Dalitz plot distribution using an isobar model and measure the magnitudes and phases of the decay coefficients. We find no evidence of CP violation for the individual components of the isobar model. The decay dynamics is dominated by the K+K- S-wave, for which we perform a partial-wave analysis in the region m(K+K-) < 2 GeV/c^2. Significant production of the f0(980) resonance, and of a spin zero state near 1.55 GeV/c^2 are required in the isobar model description of the data. The partial-wave analysis supports this observation.

    The authors present evidence for the flavor-changing neutral current decay B {yields} K*{ell}{sup +}{ell}{sup -} and a measurement of the B {yields} K{ell}{sup +}{ell}{sup -} branching fraction, where {ell}{sup +}{ell}{sup -} is either an e{sup +}e{sup -} or {mu}{sup +}{mu}{sup -} pair. The data sample analyzed comprises 88.5 x 10{sup 6} {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II e{sup +}e{sup -} storage ring. Averaging over K{sup (*)} isospin and lepton flavor, we obtain {Beta}(B {yields} K*{ell}{sup +}{ell}{sup -}) = (1.40{sub -0.49}{sup +0.57} {+-} 0.21) x 10{sup -6} and {Beta}(B {yields} K{ell}{sup +}{ell}{sup -}) = (0.68{sub -0.15}{sup +0.17} {+-} 0.04) x 10{sup -6}, where the uncertainties are statistical and systematic. The significance for the B {yields} K*{ell}{sup +}{ell}{sup -} signal is 3.0{sigma} and for B {yields} K{ell}{sup +}{ell}{sup -} the signal significance is over 7{sigma}.

  20. Tree and penguin amplitudes from B to pi pi, K pi, K bar{K}

    Zenczykowski, Piotr

    2009-01-01

    The question of the relative size of tree and penguin amplitudes is analyzed using the data on B to pi pi, B^+ to pi^+ K^0, and B^+ to K^+ \\bar{K}^0 decays. Our discussion involves an estimate of SU(3) breaking in the final quark-pair-creating hadronization process. The estimate is based on Regge phenomenology, which many years ago proved very successful in the description of soft hadronic physics. Accepting the Regge prediction as solid, it is then shown that the relative size and phase of t...

    We present a new reaction, complementary to the $J/\\psi\\rightarrow \\eta K^{*0}\\bar{K}^{*0}$ from which an $h_1$ resonance with mass around $1830$ MeV was reported from a BESIII experiment. The new reaction is $\\eta_c\\rightarrow \\phi K^*\\bar{K}^*$, or $\\eta_c(2S)\\rightarrow \\phi K^*\\bar{K}^*$. Using the information from the analysis of $J/\\psi\\rightarrow \\eta K^{*0}\\bar{K}^{*0}$, we find that the $K^*\\bar{K}^*$ invariant mass distribution for those two $\\eta_c$ decays exhibits a clear peak aro...

  3. Study of eta K(K)over-bar and eta ' K(K)over-bar with the fixed center approximation to Faddeev equations

    In the present work we investigate the three-body systems of eta K (K) over bar and eta'K (K) over bar, by taking the fixed center approximation to Faddeev equations. We find a clear and stable resonance structure around 1490 MeV in the squared eta K (K) over bar scattering amplitude, which is not sensitive to the renormalization parameters. Conversely, we get only an enhancement effect of the threshold in the eta'K (K) over bar amplitude that indicates the difficulty to bind the eta'K (K) ov...

  5. $K^{+}$ momentum spectrum from $(K^{-},K^{+})$ reactions in intranuclear cascade model

    Nara, Y; Harada, T; Engel, A

    1996-01-01

    In a framework of intranuclear cascade (INC) type calculation, we study a momentum spectrum in reactions \\KK at a beam momentum of 1.65 GeV/c. INC model calculations are compared with the relativistic impulse approximation (RIA) calculations to perform the detailed study of the reaction mechanism. We find that the INC model can reproduce the experimental data on various targets. Especially, in the low-momentum region, the forward-angle cross sections of the $(K^-,K^+)$ reaction on from light to heavy targets are consistently explained with the two-step strangeness exchange and production processes with various intermediate mesons, and $\\phi$, $a_0$ and $f_0$ productions and their decay into $K^+K^-$. In the two-step processes, inclusion of meson and hyperon resonances is found to be essential.

    A k-fold n-coloring of G is a mapping φ: V (G) → Zk(n) where Zk(n) is the collection of all ksubsets of {1,2,...,n} such that φ(u) ∩φ(v) = φ if uv ∈ E(G).If G has a k-fold n-coloring,i.e.,G is k-fold n-colorable.Let the smallest integer n such that G is k-fold n-colorable be the k-th chromatic number,denoted by χk(G).In this paper,we show that any outerplanar graph is k-fold 2k-colorable or k-fold χk(C*)-colorable,where C* is a shortest odd cycle of G.Moreover,we investigate that every planar graph with odd girth at least 10k-9(k 3) can be k-fold (2k + 1)-colorable.

  11. On family secrets and -K.

    Science.gov (United States)

    Orgad, Yariv

    2014-08-01

    In this paper I present a novel interpretation of family secrets. Leaning on Bion's concept of -K, the constitution of secrecy is interpreted in terms of family dynamics that actively prevent knowledge formation and mental growth. Family secrets are interpreted as a destructive process that attacks the family's truth-generating-space - the shared semiotic space within which meanings are constituted through family relationships. The paper explores the microstructure interpersonal process of -K through the analysis of Mike Leigh's movie, Secrets and Lies. Two scenes in the movie are used to demonstrate how -K is worked out in the form of a specific intersubjective semiotic endeavor that unconsciously blocks the process of meaning-making.

    2011-01-01

    Among the novel metrics used to study the relative importance of nodes in complex networks, k-core decomposition has found a number of applications in areas as diverse as sociology, proteinomics, graph visualization, and distributed system analysis and design. This paper proposes new distributed algorithms for the computation of the k-core decomposition of a network, with the purpose of (i) enabling the run-time computation of k-cores in "live" distributed systems and (ii) allowing the decomposition, over a set of connected machines, of very large graphs, that cannot be hosted in a single machine. Lower bounds on the algorithms complexity are given, and an exhaustive experimental analysis on real-world graphs is provided.

    Full Text Available Clustering text documents is a fundamental task in modern data analysis, requiring approaches which perform well both in terms of solution quality and computational efficiency. Spherical k-means clustering is one approach to address both issues, employing cosine dissimilarities to perform prototype-based partitioning of term weight representations of the documents.This paper presents the theory underlying the standard spherical k-means problem and suitable extensions, and introduces the R extension package skmeans which provides a computational environment for spherical k-means clustering featuring several solvers: a fixed-point and genetic algorithm, and interfaces to two external solvers (CLUTO and Gmeans. Performance of these solvers is investigated by means of a large scale benchmark experiment.

    We present a search for the decay of a B0 or B0bar meson to a K*0bar K0 or K*0 K0bar final state, using a sample of approximately 232 million BBbar events collected with the BABAR detector at the PEP-II asymmetric energy e+e- collider at SLAC. The measured branching fraction is B(B0 --> K*0bar K0) + B(B0 --> K*0 K0bar) = (0.2+0.9-0.8+0.1-0.3)x 10-6. We obtain the following upper limit for the branching fraction at 90% confidence level: B(B0 --> K*0bar K0) + B(B0 --> K*0 K0bar) phi K0 from sin(2beta).

We have measured the following asymmetry parameters relative to D+-->K-pi+pi+: A(CP)(K(S)pi+) = (-1.6+/-1.5+/-0.9)%, A(CP)(K(S)K+) = (+6.9+/-6.0+/-1.5)%, and A(CP)(K(S)K+) = (+7.1+/-6.1+/-1.2)% relative to D+-->K(S)pi+. We have also measured the relative branching ratios and found Gamma(D+-->K(0)pi+)/Gamma(D+-->K-pi+pi+) = (30.60+/-0.46+/-0.32)%, Gamma(D+-->K(0)K+)/Gamma(D+-->K-pi+pi+) = (6.04+/-0.35+/-0.30)%, and Gamma(D+-->K(0)K+)/Gamma(D+-->K(0)pi+) = (19.96+/-1.19+/-0.96)%.

    Matrix elements of weak currents involving light multi-meson states are important in many hadronic decays of both heavy leptons and heavy mesons. In this paper we focus on the latter case where the current size of the data set demands better models. The specific case of three-kaon weak matrix elements is considered and expressed as a relatively simple structure, which generalizes naturally the concept of form factor. We propose a model for the decay $D^+ \\to K^+ K^- K^+$ as an alternative to isobar model, with free parameter predicted by the theory to be fine-tuned by a fit to data. An important qualitative outcome is that we encompass naturally all final states topologies, which involve necessarily proper multi-particle structures and cannot be decomposed into simpler two-body processes. This aspect represents a significant improvement when compared to isobar model, often employed in analyses of heavy-meson decay data.

    An important feature of neuronal signalling is the increased concentration of K(+) in the extracellular space. The K(+) concentration is restored to its original basal level primarily by uptake into nearby glial cells. The molecular mechanisms by which K(+) is transferred from the extracellular...... space into the glial cell are debated. Although spatial buffer currents may occur, their quantitative contribution to K(+) clearance is uncertain. The concept of spatial buffering of K(+) precludes intracellular K(+) accumulation and is therefore (i) difficult to reconcile with the K(+) accumulation...... repeatedly observed in glial cells during K(+) clearance and (ii) incompatible with K(+)-dependent glial cell swelling. K(+) uptake into non-voltage clamped cultured glial cells is carried out by the Na(+)/K(+)-ATPase and the Na(+)/K(+)/Cl(-) cotransporter in combination. In brain slices and intact optic...

    2008-01-01

    Hadronization in tau -> K K pi nu_tau decays is driven by both vector and axial-vector currents that we study, guided by the following principles: The 1/N_C expansion -worked out at leading order, considering only the contribution of the lightest spin one resonances-, approximate chiral symmetry at low energies and the appropriate asymptotic behaviour we demand to the associated form factors. All these features are implemented in the resonance theory. Most of its couplings are determined by imposing the short-distance requirements of vector and axial-vector spectral functions within QCD. We plan to improve our prediction of the hadronic spectra using recently available experimental data.

    Let G = (V,E) be a graph. For each edge ei of G, a new vertexe′i is taken and the resulting set of vertices is denoted by E1(G). Theline splitting graph Ls(G) of a graph G is defined as the graph havingvertex set E(G)SE1(G) with two vertices adjacent if they correspondto adjacent edges of G or one corresponds to an element e′i of E1(G)and the other to an element ej of E(G) where ej is in N(ei). In thispaper we characterize graphs whose line splitting graphs are k − treesand k − ctrees.

    The K2K Long-Baseline neutrino oscillation experiment has been aquiring data since mid-1999 and has analysed those up to July of 2001. Fifty-six fully contained events are observed in the fiducial volume of the far detector where 80.6-8.0+7.3 are expected based partly on measurements near the beam production point. There is virtually no background for the contained event search. The methods established in this experiment are crucial for operation of future similar experiments to probe the nature of mixing in the neutral lepton sector, a necessary step in understanding the nature of family structure and of mass itself. A brief history and a few notes about the future and direction of the field precede the description of the experiment and its results.

    We present measurements of nu_mu disappearance in K2K, the KEK to Kamioka long-baseline neutrino oscillation experiment. One hundred and twelve beam-originated neutrino events are observed in the fiducial volume of Super-Kamiokande with an expectation of 158.1^{+9.2}_{-8.6} events without oscillation. A distortion of the energy spectrum is also seen in 58 single-ring muon-like events with reconstructed energies. The probability that the observations are explained by the expectation for no neutrino oscillation is 0.0015% (4.3sigma). In a two flavor oscillation scenario, the allowed Delta m^2 region at sin^2(2theta) is between 1.9 and 3.5 x 10^{-3} eV^2 at the 90% C.L. with a best-fit value of 2.8 x 10^{-3} eV^2.

    Non-relativistic Faddeev and Faddeev-Yakubovsky calculations were made for K^-pp, K^-ppn, K^-K^-p and K^-K^-pp kaonic nuclear clusters, where the quasi bound states were treated as bound states by employing real separable potential models for the K^-K^- and the K^-nucleon interactions as well as for the nucleon-nucleon interaction. The binding energies and spatial shrinkages of these states, obtained for various values of the KbarN interaction, were found to increase rapidly with the KbarN interaction strength. Their behaviors are shown in a reference diagram to overview possible changes by varying the KbarN interaction in the dense nuclear medium. Using the Lambda(1405) ansatz with a PDG mass of 1405 MeV/c^2 for K^-p, the following ground-state binding energies together with the wavefunctions were obtained: 51.5 MeV (K^-pp), 69 MeV (K^-ppn), 30.4 MeV (K^-K^-p) and 93 MeV (K^-K^-pp), which are in good agreement with previous results of variational calculation based on the Akaishi-Yamazaki coupled-channel pote...

    The T2K experiment is a long baseline neutrino oscillation experiment. Its main goal is to measure the last unknown lepton sector mixing angle θ13 by observing νe appearance in a νμ beam. It also aims to make a precision measurement of the known oscillation parameters, Δm232 and sin22θ23, via νμ disappearance studies. Other goals of the experiment include various neutrino cross-section measurements and sterile neutrino searches. The experiment uses an intense proton beam generated by the J-PARC accelerator in Tokai, Japan, and is composed of a neutrino beamline, a near detector complex (ND280), and a far detector (Super-Kamiokande) located 295 km away from J-PARC. This paper provides a comprehensive review of the instrumentation aspect of the T2K experiment and a summary of the vital information for each subsystem.

    A double-laser-beam lidar was successfully developed in 2010 to measure the K layer over Yanqing County, Beijing (40.5°N, 116.2°E). Comprehensive statistical analyses of sporadic K (Ks) layer parameters were conducted using two years of lidar data, and the parameters of the Ks layers and their distribution obtained by the analyses are described. The seasonal distribution of Ks occurrence was obtained, with two maxima observed in January and July, respectively. The seasonal distributions of sporadic E (Es) occurrence over Beijing differ from those of Ks occurrence. However, good correlations between Es and Ks in case by case study were found. We also found that four Ks events with peak altitudes lower than 90 km were associated with large and sharp temperature increases in five comparative examples.

The measurements of the coherence factor and strong-phase difference are made using quantum-correlated, fully-reconstructed D^0D^0-bar pairs produced in e^+e^- collisions at the \\psi(3770) resonance.

    The dose due to {sup 40}K has been estimated. Potassium is one of the most abundant elements in nature, being approximately 2% of the Earth's crust. Potassium has three isotopes {sup 39}K, {sup 40}K and {sup 41}K, two are stable while {sup 40}K is radioactive with a half life of 1.2x10{sup 9} years; there is 0.0117% {sup 40}K-to-K ratio. Potassium plays an important role in plants, animals and humans growth and reproduction. Due to the fact that K is an essential element for humans, {sup 40}K is the most abundant radioisotope in human body. In order to keep good health conditions K must be intake at daily basis trough food and beverages, however when K in ingested above the requirements produce adverse health effects in persons with renal, cardiac and hypertension problems or suffering diabetes. In 89.3% {sup 40}K decays to {sup 40}C through {beta}-decay, in 10.3% decays through electronic capture and emitting 1.46 MeV {gamma}-ray. K is abundant in soil, construction materials, sand thus {gamma}-rays produced during {sup 40}K decay contribute to external dose. For K in the body practically all {sup 40}K decaying energy is absorbed by the body; thus {sup 40}K contributes to total dose in humans and it is important to evaluate its contribution. In this work a set of {sup 40}K sources were prepared using different amounts of KCl salt, a {gamma}-ray spectrometer with a NaI(Tl) was characterized to standardized the sources in order to evaluate the dose due to {sup 40}K. Using thermoluminescent dosemeters the dose due to {sup 40}K was measured and related to the amount of {sup 40}K {gamma}-ray activity. (Author)

    In this paper, we first introduce the notion of generalized k-syzygy modules, and then give an equivalent characterization that the class of generalized k-syzygy modules coincides with that ofω-k-torsionfree modules. We further study the extension closure of the category consisting of generalized k-syzygy modules. Some known results are obtained as corollaries.

      对 Banach 空间范数引入了 k-点态粗和 k-粗的概念,利用 Banach 空间理论的方法,给出了 x ∈ S(X)为范数的 k-粗糙点和 X 的范数是 k-粗的一些充分必要条件,证明了(k +1)-粗糙点是 k-粗糙点以及 k-粗糙点与 Fr´echet 可微性的一些结果。特别地,在 k =1的情形下蕴含了关于范数的粗糙点、点态粗范数和粗范数的相应结果%  In this paper, the k- pointwise rough and k- rough norm on Banach space are introduced. By the method of Banach space theory, the some necessary and sufficient conditions of k- rough point of norm and k-rough norm of X are given respectively. We proved that (k + 1)- rough point is k- rough point and obtained some results related with k- rough point and Fr´echet differentiability. In particular, when k = 1 our results contains the results of about rough point of norm, pointwise rough norm and rough norm.

    We present preliminary measurements of the CP asymmetry parameters and CP content in B0-->K+K-Ks decays, with phiKs events excluded. In a sample of 227M BB pairs collected by the BABAR detector at the PEPII B-Factory at SLAC, we find the CP parameters to be S = -0.42 +/- 0.17 +/- 0.04 and C = 0.10 +/- 0.14 +/- 0.06, where the first error is statistical and the second is systematic. Extracting the fraction of CP -even final states from angular moments f(CP-even) = 0.89 +/- 0.08 +/- 0.06, and setting C=0, we determine sin(2beta) = 0.55 +/- 0.22 +/- 0.04 +/- 0.11, where the last error is due to uncertainty on the CP content.

    The reaction π-p → K +K -π- p at 16 GeV/ c was studied in the CERN OMEGA spectrometer and a partial-wave analysis (PWA) of the low-mass (K +K -π-) system (1.3-2.0 GeV) was performed. Only states in the unnatural spin-parity series produced by natural parity exchange are important and they approximately conserve t-channel helicity. The 1 +S K ∗overlineK wave dominates the low-mass (K +K -π-) region. We observe an enhancement in 2 -P K ∗overlineK wave at a mass of 1.7 GeV, consistent with the decay of the A 3 resonance.

    We have obtained clear signals of resonances in coupled-channel pi K - eta K scattering. Using distillation and a large basis of operators we are able to extract a precise spectrum of energy levels using the variational method. These energies are analysed using inelastic extensions of the Luescher method to obtain scattering amplitudes that clearly describe S, P and D wave resonances, corresponding to the physical K_0^*(1430), the K^*(892) and the K_2^*(1430).

    Vitamin K has important functions within the body, some of which are still being discovered. Research has shown that vitamin K is an anticalcification, anticancer, bone-forming and insulin-sensitising molecule. Recent data indicate that subclinical vitamin K deficiency is not uncommon. Additionally, vitamin K antagonists such as warfarin may cause detrimental side effects, which may partly be blunted through vitamin K supplementation.

    The rare decays K+ -> p + n -n are excellent processes to make tests of new physics at the highest scale complementary to LHC thanks to their theoretically cleaness. The NA62 experiment at CERN SPS aims to collect of the order of 100 events in two years of data taking, keeping the background at the level of 10%. Part of the experimental apparatus has been commissioned during a technical run in 2012. The physics prospects and the status of the experiment will be reviewed after the commissioning run of 2014 and the data taking in 2015.

Since Thursday 1 November, the P42 beam line of the SPS has once again been sending protons to the beryllium target to produce the K12 kaon beam line eagerly awaited by the NA62 collaboration. This was no trivial matter! The first step was to clear the decks by dismantling the entire H10 beam line and NA60 experiment, as well as most of the NA48 experiment - representing some 1000 tonnes of equipment in total! Next came the complete renovation of the infrastructure, which dated back to 1979. The operation called on the expertise of virtually all branches of the EN and GS departments, as well as the Radiation Protection group: from ...

    1989-09-01

    Under Margaret Thatcher's privatization initiative, the 65,000 MW system under the authority of the Central Electricity Generating Board (CEGB), the government owned generation and transmission company, will become three publicly held companies on January 1, 1990. National Power will receive 70% of CEGB's generating capacity including its nuclear assets. PowerGen will receive the remaining 30%. The National Grid Company will inherit CEGB's transmission assets. Barriers to entry for independent power producers are still evident, however. There is no standard contract for the purchase of power from independent producers. Furthermore, the purchase price for power is unknown and many developers feel it must rise from the current 5.4{cents}/kWh to 7.8{cents}/kWh for an adequate rate of return for private power producers. Finally, many British power experts told the trade mission they fear National Power and PowerGen, with their large generating capacities and economies of scale, may try to bar independent power producers from entering the market. They may do so by undercutting the price of independent power production and monopolizing the real estate for potential power projects in southern Britain.

    Let n and k (n ≥ k > 1) be two non-negative integers. A k-multi-hypertournament on n vertices is a pair (V, A), where V is a set of vertices with |V|= n, and A is a set of k-tuples of vertices, called arcs, such that for any k-subset S of V, A contains at least one (at most k!) of the k! k-tuples whose entries belong to S. The necessary and sufficient conditions for a non-decreasing sequence of non-negative integers to be the out-degree sequence (in-degree sequence) of some k-multi-hypertournament are given.

    The exclusive reactions $\\gamma p \\to \\bar K^0 K^+ n$ and $\\gamma p \\to \\bar K^0 K^0 p$ have been studied in the photon energy range 1.6--3.8 GeV, searching for evidence of the exotic baryon $\\Theta^+(1540)$ in the decays $\\Theta^+\\to nK^+$ and $\\Theta^+\\to p K^0$. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. The integrated luminosity was about 70 pb$^{-1}$. The reactions have been isolated by detecting the $K^+$ and proton directly, the neutral kaon via its decay to $K_S \\to \\pi^+ \\pi^-$ and the neutron or neutral kaon via the missing mass technique. The mass and width of known hyperons such as $\\Sigma^+$, $\\Sigma^-$ and $\\Lambda(1116)$ were used as a check of the mass determination accuracy and experimental resolution. Approximately 100,000 $\\Lambda^*(1520)$'s and 150,000 $\\phi$'s were observed in the $\\bar K^0 K^+ n$ and $\\bar K^0 K^0 p$ final state respectively.

  13. The aligned K-center problem

    KAUST Repository

    Braß, Peter

    2011-04-01

    In this paper we study several instances of the aligned k-center problem where the goal is, given a set of points S in the plane and a parameter k ≥ 1, to find k disks with centers on a line ℓ such that their union covers S and the maximum radius of the disks is minimized. This problem is a constrained version of the well-known k-center problem in which the centers are constrained to lie in a particular region such as a segment, a line, or a polygon. We first consider the simplest version of the problem where the line ℓ is given in advance; we can solve this problem in time O(n log2 n). In the case where only the direction of ℓ is fixed, we give an O(n2 log 2 n)-time algorithm. When ℓ is an arbitrary line, we give a randomized algorithm with expected running time O(n4 log2 n). Then we present (1+ε)-approximation algorithms for these three problems. When we denote T(k, ε) = (k/ε2+(k/ε) log k) log(1/ε), these algorithms run in O(n log k + T(k, ε)) time, O(n log k + T(k, ε)/ε) time, and O(n log k + T(k, ε)/ε2) time, respectively. For k = O(n1/3/log n), we also give randomized algorithms with expected running times O(n + (k/ε2) log(1/ε)), O(n+(k/ε3) log(1/ε)), and O(n + (k/ε4) log(1/ε)), respectively. © 2011 World Scientific Publishing Company.

    Terahertz (THz) technology is receiving increasing attention around the world due to its important potential in many application areas. Novel compact solid-state sources and detectors are being sought for THz radiation and detection. We report the realization of a THz imager based on a high- Tc superconducting (HTS) Josephson detector working above liquid nitrogen temperature (77 K). The detector, made of a YBa2Cu3O7-x (YBCO) step-edge Josephson junction, is coupled to a thin-film ring-slot antenna and a hemispheric silicon lens. Images of high visual quality are obtained which demonstrate unique properties of THz radiation such as the sensitivity to water content and the ability to penetrate packaging materials. The results should stimulate further research leading to the development of a HTS superconducting THz imaging system.

  16. Compact K-edge densitometer

    International Nuclear Information System (INIS)

    Los Alamos National Laboratory has designed, built, and is currently testing a compact K-edge densitometer for use by International Atomic Energy Agency (IAEA) inspectors. The unit, which can easily be moved from one location to another within a facility, is positioned outside a glovebox with the body of the instrument inserted into the glove. A fixture inside the glovebox fits around the body and positions a sample holder. A hand-held high-purity germanium detector powered by a battery pack and a Davidson portable multichannel analyzer (MCA) is used to measure the transmission through plutonium nitrate solutions at E/sub Y/ = 121.1 and 122.2 keV. The Davidson MCA is programmed to lead the user through the measurement procedure and perform all the data analyses. The instrument is currently installed at the Safeguards Analytical Laboratory, where IAEA personnel are evaluating its accuracy, ease of operation, and safety. 5 references, 5 figures, 5 tables

    The authors present a search for the decay of a B{sup 0} or {bar B}{sup 0} meson to a {bar K}*{sup 0} K{sup 0} or K*{sup 0} {bar K}{sup 0} final state, using a sample of approximately 232 million B{bar B} events collected with the BABAR detector at the PEP-II asymmetric energy e{sup +}e{sup -} collider at SLAC. The measured branching fraction is {Beta}(B{sup 0} {yields} {bar K}*{sup 0} K{sup 0}) + {Beta}(B{sup 0} {yields} K*{sup 0} {bar K}{sup 0}) = (0.2{sub -0.8, -0.3}{sup +0.9, +0.1}) x 10{sup -6}. They obtain the following upper limit for the branching fraction at 90% confidence level: {Beta}(B{sup 0} {yields} {bar K}*{sup 0} K{sup 0}) + {Beta}(B{sup 0} {yields} K*{sup 0} {bar K}{sup 0}) < 1.9 x 10{sup -6}. They use our result to constrain the Standard Model prediction for the deviation of the CP asymmetry in B{sup 0} {yields} {phi}K{sup 0} from sin 2{beta}.

    2007-10-01

    A 15-year fertilization experiment was conducted on an aquic brown soil to study the variations of its K fertility and the index of K deficit under different fertilization systems. The results indicated that no K application accelerated the depletion of soil K, representing a certain decrease of soil available and slow-release K. Applying K alone could not keep soil K in balance, still having a decrease of soil available and slow-release K. The application of recycled compost combined with appropriate amount of fertilizer K could compensate soil K expenditure to a certain degree, and keep the concentrations of soil available and slow-release K somewhat constant. The statistic analysis on the past years test results showed that the critical values of soil available K in corn- and soybean fields obtained by crossing method were all 73 mg x kg(-1).

    At present there is no experimental verification that the K^{0}K ^{0} system remains a non-separate system when the particles fly apart. For example, Furry's hypothesis may be considered. An experimental test of this non-separability requires producing K^{0} and K^{0} interactions. This can be done for the annihilation pp to K^{0}K^{0} with the CERN LEAR facility.

    ESA and the APME are hosting a contest for 10 - 15 year olds in nine European countries (Austria, Belgium, France, Germany, Italy, the Netherlands, Spain, Sweden and the United Kingdom). The contest is based on an interactive CD ROM, called Space Mission: Y3K, which explores space technology and shows some concrete uses of that technology in enhancing the quality of life on Earth. The CD ROM invites kids to join animated character Space Ranger Pete on an action-packed, colourful journey through space. Space Ranger Pete begins on Earth: the user navigates around a 'locker room' to learn about synthetic materials used in rocket boosters, heat shields, space suits and helmets, and how these materials have now become indispensable to everyday life. From Earth he flies into space and the user follows him from the control room in the spacecraft to a planet, satellites and finally to the International Space Station. Along the way, the user jots down clues that he or she discovers in this exploration, designing an imaginary space community and putting together a submission for the contest. The lucky winners will spend a weekend training as "junior astronauts" at the European Space Centre in Belgium (20-22 April 2001). They will be put through their astronaut paces, learning the art of space walking, running their own space mission, piloting a space capsule and re-entering the Earth's atmosphere. The competition features in various youth media channels across Europe. In the UK, popular BBC Saturday morning TV show, Live & Kicking, will be launching the competition and will invite viewers to submit their space community designs to win a weekend at ESC. In Germany, high circulation children's magazine Geolino will feature the competition in the January issue and on their internet site. And youth magazine ZoZitDat will feature the competition in the Netherlands throughout February. Space Mission: Y3K is part of an on-going partnership between the ESA's Technology Transfer

    2000-06-01

    The SPIE Education Committee has developed an outreach program aimed at enhancing the dissemination of information about optics to children in kindergarten through the 12th grade (K-12). The main impetus behind the program was that more practicing optical scientists and engineers would be willing to give lectures and demonstrations aimed at inspiring the next generation about optics if material could be made easily available. Consequently, three instructional `outreach kits' were assembled to use in teaching optics to kids in exciting and fun ways. These kits were beta-tested over the last two years at six different U.S. regional sites. Each `outreach kit' contained: (1) a workbook on Optical Demonstrations on the Overhead Projector; (2) a Science and Math Experience Manual: Light, Color and Their Uses; (3) The Optics Discovery Classroom Kit; (4) a slide show; and (5) a video on careers in optics. The best tests were aimed at evaluating the practical ways of utilizing the kits, developing easy-to-follow instructions for guiding others in their use and providing suggestions on modifications, additions, and deletions to the kits. This paper discuses this outreach program and provides details relative to the kit's composition and future plans.

  19. K-theory an introduction

    Karoubi, Max

    1978-01-01

    AT-theory was introduced by A. Grothendieck in his formulation of the Riemann- Roch theorem (cf. Borel and Serre [2]). For each projective algebraic variety, Grothendieck constructed a group from the category of coherent algebraic sheaves, and showed that it had many nice properties. Atiyah and Hirzebruch [3] con­ sidered a topological analog defined for any compact space X, a group K{X) constructed from the category of vector bundles on X. It is this ''topological J^-theory" that this book will study. Topological ^-theory has become an important tool in topology. Using- theory, Adams and Atiyah were able to give a simple proof that the only spheres which can be provided with //-space structures are S^, S^ and S'^. Moreover, it is possible to derive a substantial part of stable homotopy theory from A^-theory (cf. J. F. Adams [2]). Further applications to analysis and algebra are found in the work of Atiyah-Singer [2], Bass [1], Quillen [1], and others. A key factor in these applications is Bott periodicity (...

  20. {bar K}-NUCLEAR Deeply Bound States?

    Science.gov (United States)

    Gal, Avraham

    Following the prediction by Akaishi and Yamazaki of relatively narrow {bar K}-nuclear states, deeply bound by over 100 MeV where the main decay channel {bar K} N -> π Σ is closed, several experimental signals in stopped K- reactions on light nuclei have been interpreted recently as due to such states. In this talk I review (i) the evidence from K--atom data for a deep bar K-nucleus potential, as attractive as V{bar K}(ρ 0) ˜ -(150 - 200) MeV at nuclear matter density, that could support such states; and (ii) the theoretical arguments for a shallow potential, V{bar K}(ρ 0) ˜ -(40 - 60) MeV. I then review a recent work by Mareš, Friedman and Gal in which {bar K}-nuclear bound states are generated dynamically across the periodic table, using a RMF Lagrangian that couples the {bar K} to the scalar and vector meson fields mediating the nuclear interactions. The reduced phase space available for {bar K} absorption from these bound states is taken into account by adding a density- and energy-dependent imaginary term, underlying the corresponding {bar K}-nuclear level widths, with a strength constrained by K--atom fits. Substantial polarization of the core nucleus is found for light nuclei, with central nuclear densities enhanced by almost a factor of two. The binding energies and widths calculated in this dynamical model differ appreciably from those calculated for a static nucleus. These calculations provide a lower limit of Γ {bar K} ˜ 50 ± 10 MeV on the width of nuclear bound states for {bar K} binding energy in the range B{bar K} = 100 - 200 MeV.

    We present measurements of time-dependent CP asymmetries in $B^0 \\to \\omega K_S^0$, $f_0 (980) K_S^0$, $K_S^0 \\pi^0$ and $K^+ K^- K_S^0$ based on a sample of 535 $\\times 10^6$ $B\\bar{B}$ pairs collected at the $\\Upsilon(4S)$ resonance with the Belle detector at the KEKB energy-asymmetric $e^+ e^-$ collider. One neutral $B$ meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying $B$ meson is identified from its decay products. CP-violation parameters for each of the decay modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays.

    Λ(1405) is considered as a superposition of two resonances instead of a simple bound state of the kaon and proton. Within the framework of the Brueckner-Hartree-Fock(BHF) theory, we have investigated the K nuclear systems (S=-1), especially K- pp and K- pnn(T=1). The binding energy BK-is 23 MeV (3 MeV) and the width Γ is 62 MeV (56 MeV) for K-pp(K-pnn(T=1)).

    An algorithm for solving thesatisfiability problem is presented. It is proved that this algorithmsolves 2-SAT and Horn-SAT in linear time and k-positive SAT(in which every clause contains at most k positive literals) in time, where |F| is the length of input F,n is the number of atoms occurring in F, and ξk is thegreatest real number satisfying the equation . Compared with previous results, this nontrivialupper bound on time complexity could only be obtained for k-SAT, whichis a subproblem of k-positive SAT.

    The 2-primary torsion of the higher algebraic K-theory of the integers has been computed by Rognes and Weibel. In this paper we prove analogous results for the Hermitian K-theory of the integers with 2 inverted (denoted by Z'). We also prove in this case the analog of the Lichtenbaum conjecture for the hermitian K-theory of Z' : the homotopy fixed point set of a suitable Z/2 action on the classifying space of the algebraic K-theory of Z' is the hermitian K-theory of Z' after 2-adic completion.

    We study the productions of p-wave mesons $K^*_{0}(1430)$, $K_{1}(1270)$ and $K_{1}(1400)$ in B decays. By the generalized factorization approach, we find that the branching ratios of $B\\to K^*_{0}(1430) \\phi$ are similar to those of $B\\to K \\phi$ while the branching ratios of $B\\to K_{1}(1270) \\phi$ and $B\\to K_{1}(1400) \\phi$ are %could be $O(10^{-5})$ and $O(10^{-6})$, respectively. In terms of the observation of $B\\to K_{1}(1270) \\gamma$ by BELLE, we can remove the sign ambiguity in the mixing angle for physical states $K_1(1270)$ and $K_{1}(1400)$. In addition, we analyze annihilation contributions in the decays $B\\to K_1 \\phi$ and we conclude that they could be neglected.

    The decay $B^0 \\to D K^{*0}$ and the charge conjugate mode are studied using 1.0${\\mathrm fb}^-1$ of $pp$ collision data collected by the LHCb experiment at $\\sqrt{s} = 7TeV$ in 2011. The CP asymmetry between the $B^0 \\to D K^{*0}$ and the $\\bar{B}^0 \\to D \\bar{K }^{*0}$ decay rates, with the neutral D meson in the CP-even final state $K^+K^-$, is found to be \\begin{equation*} {\\cal A}_d^{KK} = -0.45 \\pm 0.23 \\pm 0.02, \\end{equation*} where the first uncertainty is statistical and the second is systematic. In addition, favoured $B^0 \\to D K^{*0}$ decays are reconstructed with the $D$ meson in the non-$CP$ eigenstate $K^+ \\pi^-$. The ratio of the $B$-flavour averaged decay rates in $D$ decays to $CP$ and non-$CP$ eigenstates is measured to be \\begin{equation*} {\\cal R}_d^{KK} = 1.36\\,^{+0.37}_{ -0.32} \\pm 0.07, \\end{equation*} where the ratio of the branching fractions of $D^0 \\to K^- \\pi^+$ to $D^0 \\to K^+ K^-$ decays is included as multiplicative factor. The CP asymmetries measured with two contro...

    We present preliminary measurements of the CP asymmetry parameters and CP content in B0 --> K+K-K0L decays, with B0 --> phi K0L events excluded. In a sample of 227 M B bar B pairs collected by the BaBar detector at the PEP-II B Factory at SLAC, we find the CP parameters to be S = 0.07 +/- 0.28 (stat) {+0.11} {-0.12} (syst) C = 0.54 +/- 0.22 (stat) {+0.08} {-0.09} (syst) where the first error is statistical and the second is systematic. Estimating the fraction of CP-odd final states from angular moments analysis in the K+K-K0S CP-conjugate final state, f_{odd} (K+K-K0L) = 0.92 +/- 0.07 (stat) +/- 0.06 (syst) we determine sin 2beta_{eff} = 0.09 +/- 0.33, (stat) {+0.13} {-0.14} (syst) +/- 0.10 (syst CP-cont)

    Full Text Available SEMIPARAMETRIC REGRESSIONAbstract: Classical (parametric regression techniques are based on the assumption that the independent variable is correlated linearly with the dependent variables and the pattern of this relation is known. When such assumption cannot be verified, parameter estimations fail to be reliable. In cases where the way of correlation is not known or it does not comply with the known parametric mathematical patterns, nonparametric regression techniques are to be applied. One shortcoming concerning this procedure emerges particularly in the interpretation process due to problems brought about by multidimensional aspect of the existence of more than one independent variable. Whenever confronted with a case that includes more than one independent variable, some of the independent variables correlate linearly with the dependent variable; at other times some of the independent variables might correlate nonlinearly. In order to establish a modeling for such relations, semiparametric regression models, comprising the aggregate of parametric and nonparametric regression function, are utilized. İn this study semiparametric regression definitions, estimation (backfitting algorithm, confidence bands, calculating standard errors and hypothesis testing are explained.Keywords: Additive Models, Semiparametric Regression, Backfitting Algorithm.SEMİPARAMETRİK REGRESYONÖzet: Klasik (parametrik regresyon teknikleri, bağımlı değişkenin bağımsız değişkenlerle doğrusal bir ilişki içerisinde olduğunu ve ilişkinin şeklinin biliniyor olduğunu varsayar. Bu varsayımların sağlanamaması durumunda ise parametre tahminleri güvenilir olmamaktadır. İlişkinin şeklinin bilinmediği ya da bilinen parametrik matamatiksel kalıplara uymadığı durumlarda parametrik olmayan regresyon teknikleri kullanılmaktadır. Ancak bu teknikler birden fazla bağımsız değişken olma durumunda çok boyutluluğun yarattığı sıkıntı nedeniyle

V tomto podzimním čase se dotkneme často diskutovaného problému elit a jejich postavení v současné společnosti výkonu, a pravidelně opakovaných námitek, že současná společnost elity jakoby nepotřebuje, a ani nevytváří[1]. Intelektuální elitou je vždy míněna vrstva lidí s rozhledem, sečtělých, schopných uvažovat v souvislostech; to vše jsou schopnosti vznikající ve svobodě – nejen smýšlení, tedy názoru a jeho vyjádření, ale především myšlení samého. Tato svoboda potřebuje otevření časového prostoru, kdy myšlení je samo sebou – může volně plynout, aniž by naráželo na své, či spíše vnější „produktivní“ nároky. Čas pro čtení, rozvažování či dokonce rozjímání chybí stále více, což je spojeno s nedůvěrou, že by takové počínání mohlo vůbec „k něčemu vést“. Také environmentální vzdělání vede v tomto ohledu bitvu předem ztracenou – pokouší se vyvzdorovat tento volný čas v systému požírajícímu naše děti již v útlém věku, a obhájit jej proti soustavnému nároku na vytváření nových znalostí.

    A search is made for the highly-suppressed B meson decays $B^{+}\\rightarrow K^{+}K^{+}\\pi^{-}$ and $B^{+}\\rightarrow \\pi^{+}\\pi^{+}K^{-}$ using a data sample corresponding to an integrated luminosity of 3.0 $fb^{-1}$ collected by the LHCb experiment in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. No evidence is found for the decays, and upper limits at 90\\% confidence level are determined to be $\\mathcal{B}(B^{+}\\rightarrow K^{+}K^{+}\\pi^{-}) < 1.1\\times 10^{-8}$ and $\\mathcal{B}(B^{+}\\rightarrow \\pi^{+}\\pi^{+}K^{-}) < 4.6\\times 10^{-8}$.

  15. A (k+1)-Slope Theorem for the k-Dimensional Infinite Group Relaxation

    CERN Document Server

    Basu, Amitabh; Köppe, Matthias; Molinaro, Marco

    2011-01-01

    We prove that any minimal valid function for the k-dimensional infinite group relaxation that is piecewise linear with at most k+1 slopes and does not factor through a linear map with non-trivial kernel is extreme. This generalizes a theorem of Gomory and Johnson for k=1, and Cornuejols and Molinaro for k=2.

  17. Polarization, CP asymmetry, and branching ratios in B→K*K* with the perturbative QCD approach

    International Nuclear Information System (INIS)

    We study the charmless rare decays B→K*K* within the perturbative QCD picture. We calculate not only factorizable and nonfactorizable diagrams, but also annihilation ones. Our predictions are the following: The longitudinal polarization fraction vary from 75% to 99% depending on channels, the branching ratios are of order 10-7 for B0(B0)→K*0K*0 and B±→K*±K*0(K*0), much bigger than that for B0(B0)→K*+K*-(10-8). The direct CP asymmetry in B±→K*±K*0(K*0) and B0(B0)→K*+K*- is about -15% and -65% if we choose α(φ2) as 95 deg.. The direct CP violation in B0(B0)→K*0K*0 decays is negligible if there is not strong final state interactions. Our predictions will be tested in the future B experiments

    The first observation of the decay B0→D¯(0)K(+)K(-) is reported from an analysis of 0.62 fb(-1) of pp collision data collected with the LHCb detector. Its branching fraction is measured relative to that of the topologically similar decay B(0)→D ¯(0)π(+)π(-) to be (B(B(0)→D¯(0)K(+)K(-))/B(B(0)→D¯(0)π(+)π(-))=0.056±0.011±0.007,where the first uncertainty is statistical and the second is systematic. The significance of the signal is 5.8σ. Evidence, with 3.8σ significance, for B(s)(0)→D¯(0)K(+)K(-) decays is also presented. The relative branching fraction is measured to be B(B(s)(0)→D¯(0)K(+)K(-))/B(B(0)→D¯(0)K(+)K(-))=0.90±0.27±0.20. These channels are of interest to study the mechanisms behind hadronic B decays, and open new possibilities for CP violation analyses with larger data sets. PMID:23030081

  19. Dial a Ride from k-forest

    Gupta, Anupam; Nagarajan, Viswanath; Ravi, R

    2007-01-01

    The k-forest problem is a common generalization of both the k-MST and the dense-$k$-subgraph problems. Formally, given a metric space on $n$ vertices $V$, with $m$ demand pairs $\\subseteq V \\times V$ and a ``target'' $k\\le m$, the goal is to find a minimum cost subgraph that connects at least $k$ demand pairs. In this paper, we give an $O(\\min\\{\\sqrt{n},\\sqrt{k}\\})$-approximation algorithm for $k$-forest, improving on the previous best ratio of $O(n^{2/3}\\log n)$ by Segev & Segev. We then apply our algorithm for k-forest to obtain approximation algorithms for several Dial-a-Ride problems. The basic Dial-a-Ride problem is the following: given an $n$ point metric space with $m$ objects each with its own source and destination, and a vehicle capable of carrying at most $k$ objects at any time, find the minimum length tour that uses this vehicle to move each object from its source to destination. We prove that an $\\alpha$-approximation algorithm for the $k$-forest problem implies an $O(\\alpha\\cdot\\log^2n)$-ap...

    The first observation of the decay $B^{0} \\to \\overline{D}^{0}K^{+}K^{-}$ is reported from an analysis of $0.62 \\ \\mathrm{fb}^{-1}$ of $pp$ collision data collected with the LHCb detector. Its branching fraction is measured relative to that of the topologically similar decay $B^{0} \\to \\overline{D}^{0}\\pi^{+}\\pi^{-}$ to be $\\frac{ {\\cal B}\\left(B^{0} \\to \\overline{D}^{0}K^{+}K^{-}\\right)}{ {\\cal B}\\left(B^{0} \\to \\overline{D}^{0}\\pi^{+}\\pi^{-}\\right)} = 0.056 \\pm 0.011 \\pm 0.007$, where the first uncertainty is statistical and the second is systematic. The significance of the signal is $5.8\\,\\sigma$. Evidence, with $3.8\\,\\sigma$ significance, for $B^{0}_{s} \\to \\overline{D}^{0}K^{+}K^{-}$ decays is also presented. The relative branching fraction is measured to be $\\frac{ {\\cal B}\\left(B^{0}_{s} \\to \\overline{D}^{0}K^{+}K^{-}\\right)}{ {\\cal B}\\left(B^{0} \\to \\overline{D}^{0}K^{+}K^{-}\\right)} = 0.90 \\pm 0.27 \\pm 0.20$.

    We discuss all contributions from inelastic SU(3)-symmetric rescattering in B decays into a final pair of pseudoscalar mesons $PP = \\pi \\pi$, $K\\bar{K}$, $\\pi K$. FSI-induced modifications of amplitudes obtained from the quark-line approach are described in terms of a few parameters which take care of all possible SU(3)-symmetric forms relevant for final-state interactions. Although in general it appears impossible to uniquely determine FSI effects from the combined set of all $\\pi \\pi$, $K \\...

    The real and imaginary parts of the $K_L-K_S$ mixing matrix receive contributions from all three charge-2/3 quarks: up, charm and top. These give both short- and long-distance contributions which are accessible through a combination of perturbative and lattice methods. We will discuss a strategy to compute both the mass difference, $\\Delta M_K$ and $\\epsilon_K$ to sub-percent accuracy, looking in detail at the contributions from each of the three CKM matrix element products $V_{id}^*V_{is}$ for $i=u, c$ and $t$ as described in Ref.

    The authors present a preliminary measurement of CP-violation parameters in the decay B{sup 0} {yields} K{sup +}K{sup -}K{sup 0}, using approximately 347 million B{bar B} events collected by the BABAR detector at SLAC. Reconstructing the neutral kaon as K{sub S}{sup 0} {yields} {pi}{sup +}{pi}{sup -}, K{sub S}{sup 0} {yields} {pi}{sup 0}{pi}{sup 0}, or K{sub L}{sup 0}, they analyze the Dalitz plot distribution and measure fractions to intermediate states. They extract CP parameters from the asymmetries in amplitudes and phases between B{sup 0} and {bar B}{sup 0} decays across the Dalitz plot. For decays to {phi}K{sup 0}, they find {beta}{sub eff} = 0.06 {+-} 0.16 {+-} 0.05, A{sub CP} = -0.18 {+-} 0.20 {+-} 0.10, where the first uncertainty is statistical and the second one is systematic. For decays to f{sub 0}K{sup 0}, they find {beta}{sub eff} = 0.18 {+-} 0.19 {+-} 0.04, A{sub CP} = 0.45 {+-} 0.28 {+-} 0.10. Combining all K{sup +}K{sup -}K{sup 0} events and taking account of the different CP eigenvalues of the individual Dalitz plot components, they find {beta}{sub eff} = 0.361 {+-} 0.079 {+-} 0.037, A{sub CP} = -0.034 {+-} 0.079 {+-} 0.025. The trigonometric reflection at {pi}/2 - {beta}{sub eff} is disfavored at 4.6{sigma}. They also study angular distributions in B{sup 0} {yields} K{sup +}K{sup -}K{sub S}{sup 0} and B{sup +} {yields} {phi}K{sup +} decays and measure the direct CP asymmetry in B{sup +} {yields} {phi}K{sup +} decays, A{sub CP} = 0.046 {+-} 0.046 {+-} 0.017.

    The present report documents the results of Working Group 2: B, D and K decays, of the workshop on Flavor in the Era of the LHC, held at CERN from November 2005 through March 2007. With the advent of the LHC, we will be able to probe New Physics (NP) up to energy scales almost one order of magnitude larger than it has been possible with present accelerator facilities. While direct detection of new particles will be the main avenue to establish the presence of NP at the LHC, indirect searches will provide precious complementary information, since most probably it will not be possible to measure the full spectrum of new particles and their couplings through direct production. In particular, precision measurements and computations in the realm of flavor physics are expected to play a key role in constraining the unknown parameters of the Lagrangian of any NP model emerging from direct searches at the LHC. The aim of Working Group 2 was twofold: on one hand, to provide a coherent, up-to-date picture of the status of flavor physics before the start of the LHC; on the other hand, to initiate activities on the path towards integrating information on NP from high-p{sub T} and flavor data. This report is organized as follows. In Sec. 1, we give an overview of NP models, focusing on a few examples that have been discussed in some detail during the workshop, with a short description of the available computational tools for flavor observables in NP models. Sec. 2 contains a concise discussion of the main theoretical problem in flavor physics: the evaluation of the relevant hadronic matrix elements for weak decays. Sec. 3 contains a detailed discussion of NP effects in a set of flavor observables that we identified as 'benchmark channels' for NP searches. The experimental prospects for flavor physics at future facilities are discussed in Sec. 4. Finally, Sec. 5 contains some assessments on the work done at the workshop and the prospects for future developments.

    This note is devoted to the study of K-primitive rings. It is proved that a prime ring R is K-primitive if and only if its a nonzero ideal is K-primitive, if and only if eRe is K-primitive for some nonzero idempotent e to R. It is also shown that GPI prime rings are K-primitive.

    Measurements of the pn -> p_spec dK^+K^- reaction, where p_spec is a spectator proton, have been undertaken at the Cooler Synchrotron COSY-Juelich by detecting a fast deuteron in coincidence with a K^+K^- pair in the ANKE facility. Although the proton beam energy was fixed, the moving target neutron allowed values of the non-resonant quasi-free pn -> dK^+K^- total cross section to be deduced up to an excess energy epsilon ~ 100 MeV. Evidence is found for the effects of K^-d and KKbar final state interactions. The comparison of these data with those of pp -> ppK^+K^- and pp -> dK^+Kbar shows that all the total cross sections are very similar in magnitude.

    The reaction pp -> d K^+ K^0-bar has been investigated at excess energies Q = 47.4 and 104.7 MeV above the K^+ K^0-bar threshold at COSY-Juelich. Coincident dK^+ pairs were detected with the ANKE spectrometer, and events with a missing K^0-bar invariant-mass subsequently identified. The joint analysis of invariant-mass and angular distributions reveals s-wave dominance between the two kaons, in conjunction with a p-wave between the deuteron and the kaon pair, i.e. K K-bar production via the a_0^+(980) channel. Integration of the differential distributions yields total cross sections of sigma(pp -> d K^+ K^0-bar) = (38 +/- 2(stat) +/- 14(syst)) nb and 190 +/- 4(stat) +/- 39(syst)) nb for the low and high Q values, respectively.

    The Yoneda algebra of a Koszul algebra or a D-Koszul algebra is Koszul. K2 algebras are a natural generalization of Koszul algebras, and one would hope that the Yoneda algebra of a K2 algebra would be another K2 algebra. We show that this is not necessarily the case by constructing a monomial K2 algebra for which the corresponding Yoneda algebra is not K2.

    The exclusive reactions {gamma}p {yields} {bar K}{sup 0} K{sup +} n and {gamma}p {yields} {bar K}{sup 0} K{sup 0} p have been studied in the photon energy range 1.6--3.8 GeV, searching for evidence of the exotic baryon {Theta}{sup +}(1540) in the decays {Theta}{sup +} {yields} nK{sup +} and {Theta}{sup +} {yields} pK{sup 0}. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. The integrated luminosity was about 70 pb{sup -1}. The reactions have been isolated by detecting the K{sup +} and proton directly, the neutral kaon via its decay to K{sub S} {yields} {pi}{sup +}{pi}{sup -} and the neutron or neutral kaon via the missing mass technique. The mass and width of known hyperons such as {Sigma}{sup +}, {Sigma}{sup -} and {Lambda}(1116) were used as a check of the mass determination accuracy and experimental resolution. Approximately 100,000 {Lambda}*(1520)'s and 150,000 {phi}'s were observed in the {bar K}{sup 0} K{sup +} n and {bar K}{sup 0} K{sup 0} p final state respectively. No evidence for the {Theta}{sup +} pentaquark was found in the nK{sup +} or pK{sub S} invariant mass spectra. Upper limits were set on the production cross section of the reaction {gamma}p {yields} {Theta}{sup +} {bar K}{sup 0} as functions of center-of-mass angle, nK{sup +} and pK{sub S} masses. Combining the results of the two reactions, the 95% C.L. upper limit on the total cross section for a resonance peaked at 1540 MeV was found to be 0.7 nb. Within most of the available theoretical models, this corresponds to an upper limit on the {Theta}{sup +} width, {Gamma}{sub {Theta}{sup +}}, ranging between 0.01 and 7 MeV.

    2014-01-01

    We introduce a catalog of stellar properties for stars observed by the Kepler follow-on mission, K2. We base the catalog on a cross-match between the K2 Campaign target lists and the current working version of the NASA TESS target catalog. The resulting K2-TESS Stellar Properties Catalog includes value-added information from the TESS Target Catalog, including stellar colors, proper motions, and an estimated luminosity class (dwarf/subgiant versus giant) for each star based on a reduced-proper-motion criterion. Also included is the Guest Observer program identification number(s) associated with each K2 target. The K2-TESS Stellar Properties Catalog is available to the community as a freely accessible data portal on the Filtergraph system at: http://filtergraph.vanderbilt.edu/tess_k2campaigns .

    We search for decays of a B meson into a neutral D meson and a kaon, with the D meson decaying into K+pi-pi0. This final state can be reached through the b --> c transition B- -> D0K- followed by the doubly Cabibbo-suppressed D0 --> K+pi-pi0, or the b --> u transition B- --> D0bar K- followed by the Cabibbo-favored D0bar --> K+ pi-pi 0. The interference of these two amplitudes is sensitive to the angle gamma of the unitarity triangle. We present preliminary results based on 226 10^{6} e+e- --> Y(4s) --> BBbar events collected with the BABAR detector at SLAC. We find no significant evidence for these decays and we set a limit R_ADS =(BR(B- -->[K+pi-pi0]_D K-)+ BR(B+ --> [K-pi+pi0]_D K+))/(BR(B- -->[K-p i+pi0]_D K-)+ BR(B+ --> [K+pi-pi0]_D K+)) D0bar K-)|/|A(B- --> D0bar K-)| < 0.185 at 95% confidence level.

    Mozart K.448 has been shown to improve cognitive function, leading to what is known as the Mozart Effect. Our previous work reveals positive effects of Mozart K.448 in reducing epileptiform discharges in epileptic children. In this study, we evaluated the effect of Mozart K.545 and compared the effects with those of Mozart K.448 on epileptiform discharges in children with epilepsy. Thirty-nine epileptic children with epileptiform discharges were included in the study. They received electroencephalogram examinations before, during, and after listening to Mozart K.448 and K.545, one week apart, respectively. The frequencies of epileptiform discharges were compared. There was a significant decrease in the frequency of epileptiform discharges during and right after listening to Mozart K.448 and K.545 (reduced by 35.7 ± 32.7% during Mozart K.448 and 30.3 ± 44.4% after Mozart K.448; and 34.0 ± 39.5% during Mozart K.545 and 31.8 ± 39.2% after Mozart K.545). Spectrogrammatic analysis of the two pieces of music demonstrated that both share similar spectrogrammatic characteristics. Listening to Mozart K.448 and K.545 decreased the epileptiform discharges in epileptic children. This suggests that Mozart K.448 is not the only piece of music to have beneficial effects on children with epilepsy. Other music with lower harmonics may also decrease epileptiform discharges in epileptic children. PMID:23304207

    2016-01-01

    This letter describes a completely-integrable system of Yang-Mills-Higgs equations which generalizes the Hitchin equations on a Riemann surface to arbitrary k-dimensional complex manifolds. The system arises as a dimensional reduction of a set of integrable Yang-Mills equations in 4k real dimensions. Our integrable system implies other generalizations such as the Simpson equations and the non-abelian Seiberg-Witten equations. Some simple solutions in the k=2 case are described.

We also show that in the case where k is even, if G be a graph such that $|G| > 4k+1 -4\\sqrt {k}$ and $bind(G)> {(2k-1)(n-1) \\over k(n-2)+1},$ then G is a fractional k-deleted graph.

In this paper, we characterize the potentially $K_5-P_3$, $K_5-A_3$, $K_5-K_3$ and $K_5-K_{1,3}$-graphic sequences where $A_3$ is $P_2\\cup K_2$. Moreover, we also characterize the potentially $K_5-2K_2$-graphic sequences where $pK_2$ is the matching consisted of $p$ edges.

    Full Text Available The phosphatidylinositol 3-kinases (PI3Ks are members of a family of intracellular lipid kinases that phosphorylate the 3’-hydroxyl group of phosphatidylinositol and phosphoinositides. PI3K regulate signaling pathways for neoplasia, including cell proliferation, adhesion, survival and motility. Different classes of PI3K have distinct roles in cellular signal transduction. PI3K pathway is activated by several different mechanisms in cancers, including, somatic mutation and gene amplification. In this review, we examine the literature addressing PI3K mutation status and gene amplification, with an emphasis on non-small cell lung cancer (NSCLC.

    The purpose of this review is to summarize the research to date on vitamin K status in chronic kidney disease (CKD). This review includes a summary of the data available on vitamin K status in patients across the spectrum of CKD as well as the link between vitamin K deficiency in CKD and bone dynamics, including mineralization and demineralization, as well as ectopic mineralization. It also describes two current clinical trials that are underway evaluating vitamin K treatment in CKD patients. These data may inform future clinical practice in this population.

  3. $\\bar K$-Nuclear Deeply Bound States?

    Gal, A

    2006-01-01

    Following the prediction by Akaishi and Yamazaki of relatively narrow $\\bar K$-nuclear states, deeply bound by over 100 MeV where the main decay channel $\\bar K N \\to \\pi \\Sigma$ is closed, several experimental signals in stopped $K^-$ reactions on light nuclei have been interpreted recently as due to such states. In this talk I review (i) the evidence from $K^-$-atom data for a {\\it deep} $\\bar K$-nucleus potential, as attractive as $V_{\\bar K}(\\rho_0) \\sim -(150 - 200)$ MeV at nuclear matter density, that could support such states; and (ii) the theoretical arguments for a {\\it shallow} potential, $V_{\\bar K}(\\rho_0) \\sim -(40 - 60)$ MeV. I then review a recent work by Mare\\v{s}, Friedman and Gal in which $\\bar K$-nuclear bound states are generated dynamically across the periodic table, using a RMF Lagrangian that couples the $\\bar K$ to the scalar and vector meson fields mediating the nuclear interactions. Substantial polarization of the core nucleus is found for light nuclei, with central nuclear densities...

    We consider a connection between the holographic dark energy density and the kinetic k-essence energy density in a flat FRW universe. With the choice c ≥ 1, the holographic dark energy can be described by a kinetic k-essence scalar field in a certain way. In this Letter we show this kinetic k-essential description of the holographic dark energy with c ≥ 1 and reconstruct the kinetic k-essence function F (X). © 2009 Elsevier B.V. All rights reserved.

    International Nuclear Information System (INIS)

    Recent Measurements of the parameter ε'/ε in experiments at CERN and FNAL are reviewed. The measurement of the phases of η+- and η00 in these experiments give new upper limits on CPT - violation in the K → 2π decay amplitudes and in the mass difference between K0 and K-bar0. First data from CP - LEAR are presented with a short outline of the experiment. Prospects for the future of CP - violation experiments in K - decay are discussed. (author)

  8. NaK handling and removal

    International Nuclear Information System (INIS)

    Sodium-potassium alloy is used in specific application in French Fast Breeder Reactors as: cold traps, NaK bubbler for argon purification, valves and also in experimental irradiation devices. lt has been preferred to sodium because it is liquid from + 7 deg. C for the most common peritectic alloy. After its use, NaK is considered as a hazardous waste (nuclear or not) due to its high reactivity with air and water. The most important risk remains in handling NaK systems which have not been operated for some time. The NaK will be covered with a crust of the superoxide K02 which is a strong oxidising agent. Thermodynamically, K02 will react with most organic material or metallic dust or swarfs and can also react with additional NaK to give sufficient heat to boil part of the NaK, resulting in a sudden increase in pressure and small explosions. We describe the formation given to experimenters in our Sodium School and the CEA's experience in treating specific devices for transportation, decanting of tanks, tank opening and NaK removal.

    As the optical lithography pushes toward its theoretical resolution limit 0.25k1, the application of aggressive Resolution Enhancement Techniques (RETs) are required in order to ensure necessary resolution, sufficient process window, and reasonable MEEF in critical layers. When chip makers are adopting RETs in low k1 device, there are a lot of crucial factors to take into account in the development and mass production. Those hurdles are not only difficult to overcome but also highly risky to the company, which adopts low k1 mass production strategy. But, low k1 production strategy is very attractive to all chip makers, owing to improving production capacity and cost of ownership. So, low k1 technology has been investigated by many lithography engineers. Lots of materials have been introduced. Most of them are just in RnD level. In this study, low k1 mass production issues shall be introduced, mainly. The definition of low k1 in mass production shall be suggested. And, a lot of low_k1 issues shall be introduced, also. Most of them were investigated/experienced in RnD development stage and final mass production line. Low k1 mass production, is some what different from only RnD development.

  10. Transformation groups and algebraic K-theory

    CERN Document Server

    Lück, Wolfgang

    1989-01-01

    The book focuses on the relation between transformation groups and algebraic K-theory. The general pattern is to assign to a geometric problem an invariant in an algebraic K-group which determines the problem. The algebraic K-theory of modules over a category is studied extensively and appplied to the fundamental category of G-space. Basic details of the theory of transformation groups sometimes hard to find in the literature, are collected here (Chapter I) for the benefit of graduate students. Chapters II and III contain advanced new material of interest to researchers working in transformation groups, algebraic K-theory or related fields.

    Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement of the branching ratio for the Cabibbo-favored decay mode $D^0 \\to K^-K^+\\pi^-\\pi^+$. From a sample of $2669 \\pm 101$ fully reconstructed $D^0 \\to K^-K^+\\pi^-\\pi^+$ events, we measure $\\Gamma(D^0 \\to K^-K^+\\pi^-\\pi^+)/\\Gamma(D^0 \\to K^-\\pi^-\\pi^+\\pi^+) = 0.0295 \\pm 0.0011(stat.) \\pm 0.0008(syst.)$. A coherent amplitude analysis has been performed to determine the resonant substructure of this decay mode. This analysis reveals a dominant contribution from $D^0 \\to K_1^+ K-$ modes.

    A map L is called k-symmetric if its kth iterate L(k) possesses more symmetry than L, for some value of k. In k-symmetric systems, there exists a notion of k-symmetric orbits. This paper deals with k-symmetric periodic orbits. We derive a relation between orbits that are k-symmetric with respect to

    We have searched for the decay phi -> K0 K0bar gamma, by detecting K_s pairs plus a photon and with the K_s-mesons decaying to pi^+ pi^-, in a sample of about 1.5x 10^9 phi-decays collected by the KLOE experiment at DAFNE. The reaction proceeds through the intermediate states f_0(980) gamma, a_0(980) gamma. We find five events with 3.2 events expected from background processes. We obtain the upper limit: BR (phi -> K0 K0bar gamma) < 1.9x10^-8 at 90% C.L. .

    Let D=(V, A) be a digraph with minimum indegree at least one and girth at least k, where k≥2 is an integer. In this paper, the following results were proved. A digraph D has a ( k,l)-kernel if and only if its line digraph L(D) does, and the number of (k,l)-kernels in D is equal to the number of (k,l)-kernels in L(D), where 1≤l<k. As a consequence, previous results about k-kernels in the line digraphs were gained.

  15. Constraints of unparticle physics parameters from K0-K-bar0 mixing

    International Nuclear Information System (INIS)

    The neutral kaon meson mixing plays an important role in the test of the Standard Model (SM) and new physics beyond it. Scale invariant unparticle physics induces a flavor changing neutral current (FCNC) transition of K0-K-bar0 oscillation at the tree level. In this study, we investigate the scale invariant unparticle physics effects on the K0-K-bar0 mixing. Based on the current experimental data, we give constraints of K0-K-bar0 mixing on the unparticle parameters. (authors)

  16. Depth profiles of potassium and its isotope ratio (40K/K) in several forest soils

    International Nuclear Information System (INIS)

    Depth profiles potassium and its isotope ratio (40K/K)were investigated in several forest soils from different geological and climatic backgrounds. The ratio was found not to be constant (0.0117%) but varied appreciably from 0.0085% to 0.0167% among different soils. Possible factors affecting variability of 40K/K values were considered by a multivariate factor analysis which suggested that aqueous parameters like humidity and pH might be a controlling factor in the surface soils. The amount (and probably chemical forms) of iron oxide may be another one influencing 40K/K values in mineral components at deeper portions. (author)

    We suggest fast algorithm for the matrix generator of pseudorandom numbers based on Kolmogorov-Anosov K systems which has been earliar proposed in \\cite{savvidy1,akopov1}. This algorithm reduces $N^{2}$ operation of the matrix generator to $NlnN$ and essentially reduces the generation time. It also clarifies the algebraic structure of this type of K system generators.

    Full Text Available The difficulty of quantifying vitamin K levels and determining the number of active molecules long impeded in investigations into the metabolism and physiological function of vitamin K. In the last ten years, since gamma carboxylation was first demonstrated, studies have essentially focused on: – vitamin K sources and requirements: the composition of foods and requirements with respect to molecules with vitamin K activity are beginning to be known; – vitamin K and bone: the role of osteocalcin in bone mineralization and its association with vitamin K have been studied, particularly in elderly subjects; – hemorrhagic disease of the newborn: after a number of controversies, it is now generally accepted that prophylactic treatment of all newborns should be systematic, and repeated for breast-fed infants. Vitamin K should be administerted orally except in cases of malabsorption. However, a number of essential questions remain unanswered, such as the precise role played by certain carboxyproteins (bone carboxyprotein or Gas6 and, in particular, the choice of markers for the accurate evaluation of vitamin K status in humans.

    We compare calculations of B_K with improved staggered quarks (HYP, Asqtad) and demonstrate the improved scaling behaviour that this gives rise to over previous calculations with unimproved staggered quarks. This enables us to perform the calculation of B_K on the MILC dynamical configurations (n_f=2+1), for which we give preliminary results.

    2006-01-01

    Flavour physics offers interesting probes for the exploration of the Standard Model and the search for new physics. In these lectures, we focus on B- and K-meson decays, introduce the concept of low-energy effective Hamiltonians to describe them theoretically, and discuss how physics beyond the Standard Model may generically affect the roadmap of quark-flavour physics. We address then both the implications of the B-factory data for the B_d -> J/psi K_S channel and the prospects of B_s -> J/psi phi modes for hadron colliders, and discuss how the Standard Model may be challenged through B_d -> phi K_S. Finally, as an example of a systematic flavour strategy to search for new physics, we analyze puzzling patterns in the B -> pi pi, pi K data and study their interplay with rare K and B decays.

  10. OCD metrology by floating n/k

    In this paper, one of the major contributions to the OCD metrology error, resulting from within-wafer variation of the refractive index/extinction coefficient (n/k) of the substrate, is identified and quantified. To meet the required metrology accuracy for the 65-nm node and beyond, it is suggested that n/k should be floating when performing the regression for OCD modeling. A feasible way of performing such regression is proposed and verified. As shown in the presented example, the measured CDU (3σ) with n/k fixed and n/k floating is 1.94 nm and 1.42 nm, respectively. That is, the metrology error of CDU committed by assuming n/k fixed is more than 35% of the total CDU.

  11. A vibration free closed-cycle 1 K cryostat with a 4 K pulse tube cryocooler

    Wang, Chao; Lichtenwalter, Ben

    2014-01-01

    A 1 K closed-cycle cryostat, pre-cooled by a 4 K pulse tube cryocooler, has been developed. The Cryomech PT410 pulse tube cryocooler liquefies helium in a vacuum insulated sleeve at a pressure of ˜1 atm. Liquid helium flows through a JT valve and into a 1 K pot that is evacuated by a vacuum pump. The discharged gas from the vacuum is routed to the top of the sleeve to be liquefied. This design accomplishes closed-cycle 1 K refrigeration and provides continuous cooling below 2 K. Using two XDS10 vacuum pumps and with the JT valve optimized for maximum cooling capacity, the 1 K cooling station can reach a no-load temperature of 1.51 K and provide a capacity of 225 mW at 1.76 K. The temperature oscillations on the 4 K and 1 K cooling stations are ± 3 mK. The cryostat is designed so that there is no direct mechanical contact between the pulse tube cryocooler heat exchangers and the 1 K cooling station. This design feature enables exceptionally low vibration operation at the 1 K cooling station.

    We present preliminary measurements of branching fractions and CP-violating asymmetries in decays of B mesons to two-body final states containing a K0. The results are based on a data sample of approximately 227 million Upsilon(4S) decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure BF(B+ --> K0pi+) = (26.0 +/- 1.3 +/- 1.0) x 10-6, BF(B+ --> K0barK+) = (1.45 +0.53 -0.46 +/- 0.11) x 10-6 ( K0K0bar) = (1.19 +0.40 -0.35 +/- 0.13) x 10^-6, where the first uncertainty is statistical and the second is systematic, and the upper limit is at a 90% confidence level. The significance of the BF(B+ --> K0barK+) and BF(B0 --> K0K0bar) results are 3.5 sigma and 4.5 sigma, respectively, including systematic uncertainties. In addition, we obtain a measurement of the CP-violating asymmetry for the BF(B+ --> K0pi+) mode and we determine a 90% confidence-level interval for the asymmetry in the BF(B+ --> K0barK+) mode: ACP(B+ --> K0pi+) = -0.087 +/- 0.046 +/- 0.010 and ACP(B+ -->...

    We present an updated measurement of the time-dependent CP-violating asymmetry in B0->K0S K0S K0S decays based on 347 million Upsilon(4S)->B Bbar decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. We obtain the CP asymmetries S_f = -0.66 +/- 0.26 +/- 0.08 and C_f = -0.14 +/- 0.22 +/- 0.05, where the first uncertainties are statistical and the second systematic.

    We have studied two-body charmless hadronic decays of $B$ mesons into the final states phi K and phi K^*. Using 9.7 million $B\\bar{B}$ pairs collected with the CLEO II detector, we observe the decays B- -> phi K- and B0 -> phi K*0 with the following branching fractions: BR(B- -> phi K-)=(5.5 +2.1-1.8 +- 0.6) x 10^{-6} and BR(B0 -> phi K*0)=(11.5 +4.5-3.7 +1.8-1.7) x 10^{-6}. We also see evidence for the decays B0 -> phi K0 and B- -> phi K*-. However, since the statistical significance is not overwhelming for these modes we determine upper limits of <12.3 x 10^{-6} and <22.5 x 10^{-6} (90% C.L.) respectively.

    With $1.06\\times 10^8$ $\\psi(3686)$ events collected with the BESIII detector, the branching fraction of $\\psi(3686) \\to \\omega K^+ K^-$ is measured to be $(1.54 \\pm 0.04 \\pm 0.11) \\times 10^{-4}$. This is the most precise result to date, due to the largest $\\psi(3686)$ sample, improved signal reconstruction efficiency, good simulation of the detector performance, and a more accurate knowledge of the continuum contribution. Using the branching fraction of $J/\\psi \\to \\omega K^+ K^-$, the ratio $\\mathcal{B}(\\psi(3868) \\to K^+K^-) / \\mathcal{B}(J/\\psi \\to K^+K^-)$ is determined to be $(18.4 \\pm 3.7)\\,\\%$. This constitutes a significantly improved test of the $12\\,\\%$ rule, with the uncertainty now dominated by the $J/\\psi$ branching fraction.

    2008-01-01

    Constraint satisfaction problems (CSPs) models many important intractable NP-hard problems such as propositional satisfiability problem (SAT). Algorithms with non-trivial upper bounds on running time for restricted SAT with bounded clause length k (k-SAT) can be classified into three styles: DPLL-like, PPSZ-like and Local Search, with local search algorithms having already been generalized to CSP with bounded constraint arity k (k-CSP). We generalize a DPLL-like algorithm in its simplest form and a PPSZ-like algorithm from k-SAT to k-CSP. As far as we know, this is the first attempt to use PPSZ-like strategy to solve k-CSP, and before little work has been focused on the DPLL-like or PPSZ-like strategies for k-CSP.

    1993-11-01

    Full Text Available In the present paper it is proved the K-continuity of a set-valued function which is K-hull midconvex, K-lower semicontinuous at a point and whose values are bounded K-midconvex sets; the concept of K-hull midconvexity is introduced here and it is weaker than the one of K-midconvexity. Then a generalization of the well known Theorem of Bernstein-Doech is obtained, which gives, in the particular case when the space is locally bounded, a characterization of the K-continuity of set-valued function. The theorems presented here improve some earlier results obtained by K. Nikodem (Zeszyty Nauk Politech. Lodz 559, Rospravy Mat. 114, 1989.

  20. K Basins isolation barriers summary report

    Strickland, G.C., Westinghouse Hanford

    1996-07-31

    The 105-K East and 105-K West fuel storage basins (105-K Basins) were designed and constructed in the early 1950`s for interim storage of irradiated fuel following its discharge from the reactors. The 105-K- East and 105-K West reactor buildings were constructed first, and the associated storage basins were added about a year later. The construction joint between each reactor building structure and the basin structure included a flexible membrane waterstop to prevent leakage. Water in the storage basins provided both radiation shielding and cooling to remove decay heat from stored fuel until its transfer to the Plutonium Uranium Extraction (PUREX) Facility for chemical processing. The 105-K West Reactor was permanently shut down in February 1970; the 105-K East Reactor was permanently shut down in February 1971. Except for a few loose pieces, fuel stored in the basins at that time was shipped to the PUREX Facility for processing. The basins were then left idle but were kept filled with water. The PUREX Facility was shut down and placed on wet standby in 1972 while N Reactor continued to operate. When the N Reactor fuel storage basin began to approach storage capacity, the decision was made to modify the fuel storage basins at 105-K East and 105-K West to provide additional storage capacity. Both basins were subsequently modified (105-K East in 1975 and 105-K West in 1981) to provide for the interim handling and storage of irradiated N Reactor fuel. The PUREX Facility was restarted in November 1983 to provide 1698 additional weapons-grade plutonium for the United States defense mission. The facility was shut down and deactivated in December 1992 when the U.S. Department of Energy (DOE) determined that the plant was no longer needed to support weapons-grade plutonium production. When the PUREX Facility was shut down, approximately 2.1 x 1 06 kg (2,100 metric tons) of irradiated fuel aged 7 to 23 years was left in storage in the 105-K Basins pending a decision on

    In the absence of K(+) on both sides of the membrane, delivery of standard activating pulses collapses the Shaker B K(+) conductance. Prolonged depolarizations restore the ability to conduct K(+). It has been proposed that the collapse of the conductance results from the dwelling of the channels in a stable closed (noninactivated) state (, J. Physiol. (Lond.). 499:3-15). Here it is shown that 1) Ba(2+) impedes the collapse of the K(+) conductance, protecting it from both sides of the membrane...

    We prove that every projective special K\\"ahler manifold with \\emph{regular boundary behaviour} is complete and defines a family of complete quaternionic K\\"ahler manifolds depending on a parameter $c\\ge 0$. We also show that, irrespective of its boundary behaviour, every complete projective special K\\"ahler manifold with \\emph{cubic prepotential} gives rise to such a family. Examples include non-trivial deformations of non-compact symmetric quaternionic K\\"ahler manifolds.

    A muon range detector (MRD) has been constructed as a near detector for the KEK-to-Kamioka long-baseline neutrino experiment (K2K). It monitors the neutrino beam properties at the near site by measuring the energy, angle and production point of muons produced by charged-current neutrino interaction. The detector has been working stably since the start of the K2K experiment.

  5. Quantum Mechanics and locality in the K0 K-bar0 system experimental verification possibilities

    International Nuclear Information System (INIS)

    It is shown that elementary Quantum Mechanics, applied to the K0 K-bar0 system, predicts peculiar long range EPR correlations. Possible experimental verifications are discussed, and a concrete experiment with anti-protons annihilations at rest is proposed. A pedestrian approach to local models shows that K0 K-bar0 experimentation could provide arguments to the local realism versus quantum theory controversy. (author). 17 refs., 23 figs

    We propose to build on our Cycles 11-12 program of Spitzer photometry of planets from the K2 survey by enlarging our sample to interesting exoplanets from the continuing K2 mission. Our team has shown that we can carry out this program end to end, starting with finding interesting candidate stars/planets in the K2 data stream, validating them using both proven Kepler techniques and ground-based observations, selecting and executing the Spitzer observations, and analyzing the Spitzer data in conjunction with the K2 data. To date we have observed or scheduled 38 transits/eclipses of 27 exoplanets. We will observe stars in K2 fields 0 through 15 and foresee executing over 60 AOR's on over 40 exoplanets. In the end, we expect to have a greatly improved characterization of exoplanets and their orbits than would be possible from the K2 data alone. This will be vital for JWST follow-up. In addition to improvements in ephemerides, these Spitzer observations will look for transit timing variations, analyze exoplanet atmospheres, study young exoplanets, and provde early TESS follow-up. This work will add substantially to the extensive exoplanet legacy of the Spitzer mission. This is a Generic Target proposal: The fields to be studied and their visibility windows are known, but until the K2 data is analyzed and the targets vetted, we cannot specify exact AORs.

  7. Categorical Foundations for K-Theory

    CERN Document Server

    Michel, Nicolas

    2011-01-01

    Recall that the definition of the $K$-theory of an object C (e.g., a ring or a space) has the following pattern. One first associates to the object C a category A_C that has a suitable structure (exact, Waldhausen, symmetric monoidal, ...). One then applies to the category A_C a "$K$-theory machine", which provides an infinite loop space that is the $K$-theory K(C) of the object C. We study the first step of this process. What are the kinds of objects to be studied via $K$-theory? Given these types of objects, what structured categories should one associate to an object to obtain $K$-theoretic information about it? And how should the morphisms of these objects interact with this correspondence? We propose a unified, conceptual framework for a number of important examples of objects studied in $K$-theory. The structured categories associated to an object C are typically categories of modules in a monoidal (op-)fibred category. The modules considered are "locally trivial" with respect to a given class of trivia...

  8. Quantitation of vitamin K in human milk

    International Nuclear Information System (INIS)

    A quantitative method was developed for the assay of vitamin K in human colostrum and milk. The procedure combines preparative and analytical chromatography on silica gel in a nitrogen atmosphere followed by reversed phase high performance liquid chromatography (HPLC). Two HPLC steps were used: gradient separation with ultraviolet (UV) detection followed by isocratic separation detected electrochemically. Due to co-migrating impurities, UV detection alone is insufficient for identification of vitamin K. Exogenous vitamin K was shown to equilibrate with endogenous vitamin K in the samples. A statistical method was incorporated to control for experimental variability. Vitamin K1 was analyzed in 16 pooled milk samples from 7 donors and in individual samples from 15 donors at 1 month post-partum. Vitamin K1 was present at 2.94 +/- 1.94 and 3.15 +/- 2.87 ng/mL in pools and in individuals, respectively. Menaquinones, the bacterial form of the vitamin, were not detected. The significance of experimental variation to studies of vitamin K in individuals is discussed

    Vitamin K is a cofactor for γ-glutamyl carboxylase, which catalyzes the posttranslational conversion of specific glutamyl residues to γ-carboxyglutamyl residues in a variety of vitamin K-dependent proteins (VKDPs) involved in blood coagulation, bone and cartilage metabolism, signal transduction, and cell proliferation. Despite the great advances in the genetic, structural, and functional studies of VKDPs as well as the enzymes identified as part of the vitamin K cycle which enable it to be repeatedly recycled within the cells, little is known of the identity and roles of key regulators of vitamin K metabolism in mammals and humans. This review focuses on new insights into the molecular mechanisms underlying the intestinal absorption and in vivo tissue conversion of vitamin K1 to menaquinone-4 (MK-4) with special emphasis on two major advances in the studies of intestinal vitamin K transporters in enterocytes and a tissue MK-4 biosynthetic enzyme UbiA prenyltransferase domain-containing protein 1 (UBIAD1), which participates in the in vivo conversion of a fraction of dietary vitamin K1 to MK-4 in mammals and humans, although it remains uncertain whether UBIAD1 functions as a key regulator of intracellular cholesterol metabolism, bladder and prostate tumor cell progression, vascular integrity, and protection from oxidative stress.

  17. Warped K\\"ahler potentials and fluxes

    CERN Document Server

    Martucci, Luca

    2016-01-01

    The four-dimensional effective theory for type IIB warped flux compactifications proposed in [1] is completed by taking into account the backreaction of the K\\"ahler moduli on the three-form fluxes. The only required modification consists in a flux-dependent contribution to the chiral fields parametrising the K\\"ahler moduli. The resulting supersymmetric effective theory satisfies the no-scale condition and consistently combines previous partial results present in the literature. Similar results hold for M-theory warped compactifications on Calabi-Yau fourfolds, whose effective field theory and K\\"ahler potential are also discussed.

    The EPR spectra of nitrosyl hemoglobin and myoglobin in different conditions (native, denatured and lyophilized), as well as of hematin-NO were obtained in the temperature range of 80 K-280 K. There is a substantial and reversible.decrease of the areas of the EPR spectra of all the hemoglobin samples above 150 K. The interpretation of the results implies the existence of two conformational states in thermal equilibrium only one of which is EPR detectable. Thermodynamical parameters are determined for the hexa and penta-coordinated cases. (author). 25 refs, 3 figs.

Our proof uses modularity, the Artin-Tate conjecture and class group theory. With different techniques, the result has been established by Elkies to show that Mordell-Weil rank 18 over Q is impossible for an elliptic K3 surface. We then apply our methods to general singular K3 surfaces, i.e. with Neron-Severi group of rank 20, but not ...

  3. LHCb: Measuring B to mu mu K

    CERN Multimedia

    De Cian, M

    2009-01-01

    The Flavour Changing Neutral Current decay B to mu mu K, which only occurs via loop processes in the SM, is sensitive to contributions from a variety of possible new physics sources. LHCb, the dedicated b physics experiment at the LHC, will record an unprecedented number of B to mu mu K decays, allowing precision measurements of a large number of variables, which will provide evidence or place constraints for physics beyond the SM. This poster gives a short overview of the detector, introduces some of these variables and presents a selection for B to mu mu K.

    Thompson, David C.; Bennett, Janine C.; Pebay, Philippe Pierre

    2009-11-01

    This report summarizes existing statistical engines in VTK/Titan and presents both the serial and parallel k-means statistics engines. It is a sequel to [PT08], [BPRT09], and [PT09] which studied the parallel descriptive, correlative, multi-correlative, principal component analysis, and contingency engines. The ease of use of the new parallel k-means engine is illustrated by the means of C++ code snippets and algorithm verification is provided. This report justifies the design of the statistics engines with parallel scalability in mind, and provides scalability and speed-up analysis results for the k-means engine.

    The ongoing discussion concerning the nature of the scalar resonances f_0(980) and a_0(980) implicated to extend the studies of the pp -> ppK+K- reaction near the production threshold. Furthermore, such elementary production processes allow to study the interaction of the outgoing particles due to their low relative momenta. Therefore, final state interactions in the pK or K Anti-K system can be perfectly studied in such experiments. The acquired data at the excess energies Q=10 and 28 MeV have been taken at COSY-11 and the status of the ongoing analysis will be presented.

  1. Results and Prospects from T2K

    CERN Document Server

    Duffy, Kirsty

    2016-01-01

    As measurements of the neutrino oscillation parameters improve it is becoming more interesting to study antineutrino oscillations, to investigate CP and CPT violation in the lepton sector and nonstandard matter effects. We present the most recent T2K antineutrino oscillation results, from data collected using a muon antineutrino-enhanced neutrino beam corresponding to 4.01E20 protons on target. The first analysis of electron antineutrino appearance at T2K is presented, as well as world-leading measurements of the dominant oscillation parameters for muon antineutrino disappearance. T2K measures $\\sin^2(\\bar{\\theta}_{23}) = 0.46^{+0.14}_{-0.06}$ and $\\Delta \\bar{m}^2_{32} = 2.50^{+0.3}_{-0.2} \\times 10^{-3} \\mbox{eV}^2$, which is consistent with previous T2K measurements of the neutrino oscillation parameters and existing antineutrino measurements.

  6. Inflation from Nilpotent K\\"ahler Corrections

    CERN Document Server

    McDonough, Evan

    2016-01-01

    We develop a new class of supergravity cosmological models where inflation is induced by terms in the K\\"ahler potential which mix a nilpotent superfield $S$ with a chiral sector $\\Phi$. As the new terms are non-(anti)holomorphic, and hence cannot be removed by a K\\"ahler transformation, these models are intrinsically K\\"ahler potential driven. Such terms could arise for example due to a backreaction of an anti-D3 brane on the string theory bulk geometry. We show that this mechanism is very general and allows for a unified description of inflation and dark energy, with controllable SUSY breaking at the vacuum. When the internal geometry of the bulk field is hyperbolic, we prove that small perturbative K\\"ahler corrections naturally lead to $\\alpha$-attractor behaviour, with inflationary predictions in excellent agreement with the latest Planck data

    2015-02-01

    Cathepsin K, a cysteine protease, is an essential enzyme in degradation of collagen type I. Since cathepsin K is relatively specific to osteoclasts, it represents a promising candidate for drug development. In the past decades, efforts have been made in developing highly potent, selective and orally applicable cathepsin K inhibitors. In contrast to balicatib and relacatib, whose drug development programmes were stopped due to cutaneous side-effects related to limited drug specificity, the more specific cathepsin K inhibitors odanacatib (ODN) and ONO-5334 have entered clinical trials. Odanacatib progressively increases bone mineral density (BMD) and decreases bone resorption markers in postmenopausal women with low BMD. Its clinical efficacy and safety was confirmed by several clinical studies but indicates that odanacatib is characterized by a resolution-of-effect with increases in bone resorption and rapid decreases in BMD following treatment discontinuation. A phase III fracture prevention study in postmenopausal women with osteoporosis is currently in the final phase. PMID:25572547

  12. K-independent percolation on trees

    CERN Document Server

    Mathieu, Pierre

    2011-01-01

    Consider the class of k-independent bond, respectively site, percolations with parameter p on an infinite tree T. We derive bounds on p in terms of k and the branching number br(T) of T for both a.s. percolation and a.s. nonpercolation. The bounds are tight for the whole class, coincide for bond and site percolation and are continuous functions of br(T). This extends previous results by Lyons for the independent (k=0) case and by Bollobas & Balister for the 1-independent bond percolation case. Central to our argumentation are moment method and capacity estimates \\`a la Lyons supplemented by explicit percolation models inspired by the work of Bollobas & Balister. An indispensable tool is the minimality and explicit construction of Shearer's measure on the k-fuzz of Z.

    A measurement of the time-integrated $CP$ asymmetry in the Cabibbo-suppressed decay $D^0\\rightarrow K^-K^+$ is performed using pp collision data, corresponding to an integrated luminosity of 3fb$^-1$, collected with the LHCb detector at centre-of-mass energies of 7 and 8 TeV. The flavour of the charm meson at production is determined from the charge of the pion in $D^{*+}\\rightarrow D^0 \\pi^+$ and $D^{*-}\\rightarrow \\bar{D^0} \\pi^-$ decays. The time-integrated $CP$ asymmetry $A_{CP}(K^-K^+)$ is obtained assuming negligible $CP$ violation in charm mixing and in Cabibbo-favoured $D^0\\rightarrow K^-\\pi^+$, $D^+\\rightarrow K^-\\pi^+\\pi^+$ and $D^+\\rightarrow \\bar{K^0}\\pi^+$ decays used as calibration channels. It is found to be $A_{CP}(K^-K^+)=(0.14\\pm0.15(stat)\\pm0.10(syst))\\%$. A combination of this result with previous LHCb measurements yields $A_{CP}(K^-K^+)=(0.04\\pm0.12(stat)\\pm0.10(syst))\\%$, $A_{CP}(\\pi^-\\pi^+)=(0.07\\pm0.14(stat)\\pm0.11(syst))\\%$.

  14. The Hidden K-edge Signal in K-edge Imaging

    K-edge imaging is commonly used for viewing contrast pharmaceuticals in a variety of multi-energy x-ray imaging techniques, ranging from dual-energy and spectral computed tomography to fluoroscopy. When looking for the K-edge signal of a specific contrast, by taking measurements either side of the K-edge, it is found that the K-edge is not always observable for low concentrations. We have also observed that the ability to see the K-edge is unit dependent - a K-edge that is not observable in computed tomography (CT) reconstructed linear attenuation units can often be made visible by converting to Hounsfield units. This paper presents an investigation of this K-edge hiding phenomenon. We conclude that if a multi-energy x-ray measurement of any K-edge material contains a signal of any other material, then there will be a positive concentration of that K-edge material below which its K-edge cannot be observed without extracting the K-edge signal through means of basis decomposition. Mathematical descriptions of t...

  15. Assembly Stoichiometry of the GluK2/GluK5 Kainate Receptor Complex

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available Ionotropic glutamate receptors assemble as homo- or heterotetramers. One well-studied heteromeric complex is formed by the kainate receptor subunits GluK2 and GluK5. Retention motifs prevent trafficking of GluK5 homomers to the plasma membrane, but coassembly with GluK2 yields functional heteromeric receptors. Additional control over GluK2/GluK5 assembly seems to be exerted by the amino-terminal domains, which preferentially assemble into heterodimers as isolated domains. However, the stoichiometry of the full-length GluK2/GluK5 receptor complex has yet to be determined, as is the case for all non-NMDA glutamate receptors. Here, we address this question, using a single-molecule imaging technique that enables direct counting of the number of each GluK subunit type in homomeric and heteromeric receptors in the plasma membranes of live cells. We show that GluK2 and GluK5 assemble with 2:2 stoichiometry. This is an important step toward understanding the assembly mechanism, architecture, and functional consequences of heteromer formation in ionotropic glutamate receptors.

    2016-01-01

    Based on our Faddeev-Yakubowsky calculations of four-body kaonic nuclear systems it was revealed that the structure of K-K-pp is well approximated by two Lambda*=K-p's with strong mutual attraction. It is vitally important to study this nucleus, as it is an essential gateway toward multi-Lambda* nuclei. Two experimental proposals are presented: i) production of K-K-pp by p+p reactions at T_p = 7 GeV, and ii) search for K-K-pp from the invariant mass of M(Lambda-Lambda) around 2.6 GeV/c2 in high-energy HI reactions.

  20. Balanced K-satisfiability and biased random K-satisfiability on trees.

    Science.gov (United States)

    Sumedha; Krishnamurthy, Supriya; Sahoo, Sharmistha

    2013-04-01

    We study and solve some variations of the random K-satisfiability (K-SAT) problem—balanced K-SAT and biased random K-SAT—on a regular tree, using techniques we have developed earlier. In both these problems as well as variations of these that we have looked at, we find that the transition from the satisfiable to the unsatisfiable regime obtained on the Bethe lattice matches the exact threshold for the same model on a random graph for K = 2 and is very close to the numerical value obtained for K = 3. For higher K, it deviates from the numerical estimates of the solvability threshold on random graphs but is very close to the dynamical one-step-replicasymmetry-breaking threshold as obtained from the first nontrivial fixed point of the survey propagation algorithm.

    We discover several magnetic Feshbach resonances in collisions of ultracold {sup 39}K atoms, by studying atom losses and molecule formation. Accurate determination of the magnetic-field resonance locations allows us to optimize a quantum collision model for potassium isotopes. We employ the model to predict the magnetic-field dependence of scattering lengths and of near-threshold molecular levels. Our findings will be useful to plan future experiments on ultracold {sup 39}K atoms and molecules.

    The analogue of the McKay-Thompson series for the proposed Mathieu group action on the elliptic genus of K3 is analysed. The corresponding NS-sector twining characters have good modular properties and satisfy remarkable replication identities. These observations provide strong support for the conjecture that the elliptic genus of K3 carries indeed an action of the Mathieu group M24.

    We estimate the coupling of K* vector meson to the N-->Theta+ transition employing the unitary simmetry, vector meson dominance, and results of the GRAAL Collaboration on the eta photoproduction off the neutron. Our small numerical value confirms that the CLAS Collaboration null results do not contradict to theoretical expectations for the Theta-production. We also estimate the K*-coupling for the N-->Sigma* excitation, with Sigma* being the Sigma-like antidecuplet partner of the Theta+ baryon.

  9. Caryophyllales: Evaluating phylogenetic signal in trnK intron versus matK

    Sunny S. CRAWLEY; Khidir W. HILU

    2012-01-01

    We assess the phylogenetic information in trnK intron at the ordinal level using the Caryophyllales and compare it with that derived from matK.The trnK gene is split into two exons by an intron that includes the matK gene.The plastid trnK is a tRNA gene encoding Lysine(UUU),whereas the matK gene is a putative group Ⅱ intron maturase.The two regions are usually coamplified,and trnK intron is partially sequenced but its sequences are often excluded from phylogenetic reconstruction at deep historic levels.This study shows that the two regions are comparable in proportion of variable sites,possess a comparable pattern of substitution rates per site,and display similar phylogenetic informativeness profiles and per-site informativeness.Phylogenetic analyses show strong congruence between phylogenetic trees based on matK and trnK intron partitioned datasets from 45 genera representing 30 of the 34 recognized Caryophyllales families.The trnK intron alone provides a relatively well-resolved topology for the order.Combining the trnK intron with matK sequence data resulted in six most parsimonious trees,differing only in the placement of Claytonia (Portulacaceae) within the noncore group.A well-supported major basal split in the order into core and noncore Caryophyllales with Rhabdodendraceae,Simmondsiaceae,and Asteropeiaceae as sister to remaining core lineages is evident in partitioned and combined analyses.The placement of these three families has been disputable,impacting the overall backbone topology of the Caryophyllales.This study demonstrates the cost effectiveness of using the trnK intron along with matK (both substitutions and insertions/deletions) at deeper phylogenetic level.

Meanwhile,we confirmed the differential expression of CRKL and Stathmin in both K562 and K562/ADM cells by Western blot analysis.Furthermore,we used RNA interference to silence the CRKL gene expression.Results Among the 9 differentially expressed proteins,3 were up-regulated in K562/ADM cells,while 6 were down-regulated in the K562/ADM cells compared with its parent cell line.The expression of CRKL was up-regulated significantly in K562/ADM cells,and it can be decreased by recombinant lentivirus.Moreover,the multidrug resistance of K562/ADM cells was efficiently reversed by silence of CRKL gene expression.Conclusions The data provided the differentially expressed proteins jn K562 and jts resistant cell line and highlights the power of 2D-DIGE for the discovery of resistance markers in cancer.We found CRKL may be a new protein involved in the multidrug resistanse of leukaemia cells.

    Statistical downscaling provides a technique for deriving local-scale information of precipitation and temperature from numerical weather prediction model output. The K-nearest neighbor (K-nn) is a new analog-type approach that is used in this paper to downscale the National Centers for Environmental Prediction 1998 medium-range forecast model output. The K-nn algorithm queries days similar to a given feature vector in this archive and using empirical orthogonal function analysis identifies a subset of days (K) similar to the feature day. These K days are then weighted using a bisquare weight function and randomly sampled to generate ensembles. A set of 15 medium-range forecast runs was used, and seven ensemble members were generated from each run. The ensemble of 105 members was then used to select the local-scale precipitation and temperature values in four diverse basins across the contiguous United States. These downscaled precipitation and temperature estimates were subsequently analyzed to test the performance of this downscaling approach. The downscaled ensembles were evaluated in terms of bias, the ranked probability skill score as a measure of forecast skill, spatial covariability between stations, temporal persistence, consistency between variables, and conditional bias and to develop spread-skill relationships. Though this approach does not explicitly model the space-time variability of the weather fields at each individual station, the above statistics were extremely well captured. The K-nn method was also compared with a multiple-linear-regression-based downscaling model.

  12. K basins sludge removal sludge pretreatment system

    International Nuclear Information System (INIS)

    The Spent Nuclear Fuels Program is in the process of planning activities to remove spent nuclear fuel and other materials from the 100-K Basins as a remediation effort for clean closure. The 105 K- East and K-West Basins store spent fuel, sludge, and debris. Sludge has accumulated in the 1 00 K Basins as a result of fuel oxidation and a slight amount of general debris being deposited, by settling, in the basin water. The ultimate intent in removing the sludge and fuel is to eliminate the environmental risk posed by storing fuel at the K Basins. The task for this project is to disposition specific constituents of sludge (metallic fuel) to produce a product stream through a pretreatment process that will meet the requirements, including a final particle size acceptable to the Tank Waste Remediation System (TWRS). The purpose of this task is to develop a preconceptual design package for the K Basin sludge pretreatment system. The process equipment/system is at a preconceptual stage, as shown in sketch ES-SNF-01 , while a more refined process system and material/energy balances are ongoing (all sketches are shown in Appendix C). Thus, the overall process and 0535 associated equipment have been conservatively selected and sized, respectively, to establish the cost basis and equipment layout as shown in sketches ES- SNF-02 through 08

  14. Vitamin K status in cystic fibrosis patients

    Full Text Available Vitamin K belongs to the family of fat-soluble vitamins and plays an important role in hemostasis, bone metabolism and may affect cerebral sphingolipid synthesis. It is a cofactor necessary for posttranslational γ-carboxylation of glutamyl residues in selected proteins such as the osteocalcin, and procoagulation factors II, VII, IX, X. Vitamin K deficient individuals appear to have more undercarboxylated proteins, which are functionally defective. The vitamin K deficiency has been frequently documented in patients with cystic fibrosis. The main possible causes of this deficiency include: fat malabsorption due to pancreatic exocrine insufficiency, cholestatic or  noncholestatic liver disease, reduced production of vitamin K by colonic flora related to chronic antibiotic treatments, bowel resections and increased mucous accumulation in the bowel. CF patients are more prone to osteopenia, caused by chronic vitamin K shortage, than to coagulopathy. Despite available evidence, which strongly suggests that all CF patients are at risk for developing vitamin K deficiency, its supplementation doses have not been established. Recent recommendations from Europe and the UK have suggested varied doses ranging from 0.3 mg/day to 10 mg/week. Further studies, both cross sectional and longitudinal interventional, are still required to determine routine and therapeutic supplementation doses.

    Today's advanced scenario where each information is available in one click, data security is the main aspect. Individual information which sometimes needs to be hiding is easily available using some tricks. Medical information, income details are needed to be kept away from adversaries and so, are stored in private tables. Some publicly released information contains zip code, sex, birth date. When this released information is linked with the private table, adversary can detect the whole confidential information of individuals or respondents, i.e. name, medical status. So to protect respondents identity, a new concept k-anonymity is used which means each released record has at least (k-1) other records in the release whose values are distinct over those fields that appear in the external data. K-anonymity can be achieved easily in case of single sensitive attributes i.e. name, salary, medical status, but it is quiet difficult when multiple sensitive attributes are present. Generalization and Suppression are used to achieve k-anonymity. This paper provides a formal introduction of k-anonymity and some techniques used with it l-diversity, t-closeness. This paper covers k-anonymity model and the comparative study of these concepts along with a new proposed concept for multiple sensitive attributes.

    The decay bar B -> bar K* (-> bar K pi) l+ l- offers great opportunities to explore the physics at and above the electroweak scale by means of an angular analysis. We investigate the physics potential of the seven CP asymmetries plus the asymmetry in the rate, working at low dilepton mass using QCD factorization at next-to leading order (NLO). The b ->s CP asymmetries are doubly Cabibbo-suppressed \\lesssim 1 % in the Standard Model and its extensions where the CKM matrix is the only source of CP violation. Three CP asymmetries are T-odd, and can be O(1) in the presence of non-standard CP violation. The T-even asymmetries can reach O(0.1), limited by the small strong phases in the large recoil region. We furthermore point out an easy way to measure CP phases from time-integrated, untagged bar B_d, B_d -> K* (-> K0 pi0) l+ l- and bar B_s,B_s -> phi (-> K+ K-) l+ l- decays. Analyses of these CP asymmetries can rule out, or further support the minimal description of CP violation through the CKM mechanism. Experim...

  17. Cathepsin K: a unique collagenolytic cysteine peptidase.

    Cathepsin K has emerged as a promising target for the treatment of osteoporosis in recent years. Initially identified as a papain-like cysteine peptidase expressed in high levels in osteoclasts, the important role of this enzyme in bone metabolism was highlighted by the finding that mutations in the CTSK gene cause the rare recessive disorder pycnodysostosis, which is characterized by severe bone anomalies. At the molecular level, the physiological role of cathepsin K is reflected by its unique cleavage pattern of type I collagen molecules, which is fundamentally different from that of other endogenous collagenases. Several cathepsin K inhibitors have been developed to reduce the excessive bone matrix degradation associated with osteoporosis, with the frontrunner odanacatib about to successfully conclude Phase 3 clinical trials. Apart from osteoclasts, cathepsin K is expressed in different cell types throughout the body and is involved in processes of adipogenesis, thyroxine liberation and peptide hormone regulation. Elevated activity of cathepsin K has been associated with arthritis, atherosclerosis, obesity, schizophrenia, and tumor metastasis. Accordingly, its activity is tightly regulated via multiple mechanisms, including competitive inhibition by endogenous macromolecular inhibitors and allosteric regulation by glycosaminoglycans. This review provides a state-of-the-art description of the activity of cathepsin K at the molecular level, its biological functions and the mechanisms involved in its regulation. PMID:23629523

    We present a preliminary measurement of CP-violation parameters in the decay B0 -> K+K-K0, using approximately 347 million BBbar events collected by the BABAR detector at SLAC. Reconstructing the neutral kaon as KS -> pi+pi-, KS -> pi0pi0, or KL, we analyze the Dalitz plot distribution and measure fractions to intermediate states. We extract CP parameters from the asymmetries in amplitudes and phases between B0 and B0bar decays across the Dalitz plot. For decays to phiK0, we find beta_eff=0.06 +/- 0.16 +/- 0.05, Acp=-0.18 +/- 0.20 +/- 0.10, where the first uncertainty is statistical and the second one is systematic. For decays to f0K0, we find beta_eff=0.18 +/- 0.19 +/- 0.04, Acp=0.45 +/- 0.28 +/- 0.10. Combining all KKK0 events and taking account of the different CP eigenvalues of the individual Dalitz plot components, we find beta_eff = 0.361 +/- 0.079 +/- 0.037, Acp = -0.034 +/- 0.079 +/- 0.025. The trigonometric reflection at pi/2 - beta_eff is disfavored at 4.6 sigma. We also study angular distributions ...

    Cryogenic refrigeration systems are necessary for numerous applications. Gas purification and distillation require temperatures between 15 K and 200 K depending on the application, space simulation chambers down to 15 K, superconductivity between 1.8 K and up to 75 K (magnets, cavities or HTS devices like cables, FCL, SMES, etc), Cold Neutron Sources between 15 and 20 K, etc. Air Liquide Advanced Technologies is designing and manufacturing refrigerators since 60 years to satisfy those needs. The step by step developments achieved have led to machines with higher efficiency and reliability. In 1965, reciprocating compressors and Joule Thomson expansion valves were used. In 1969, centripetal expanders began to be used. In 1980, oil lubricated screw compressors took the place of reciprocating compressors and a standard range of Claude cycle refrigerators was developed: the HELIAL series. 1980 was also the time for cryogenic centrifugal compressor development. In 2011, driven by the need for lower operational cost (high efficiency and low maintenance), cycle oil free centrifugal compressors on magnetic bearings were introduced instead of screw compressors. The power extracted by centripetal expanders was recovered. Based on this technology, a range of Turbo-Brayton refrigerators has been designed for temperatures between 40 K and 150 K. On-going development will enable widening the range of Turbo-Brayton refrigerators to cryogenic temperatures down to 15 K.. Cryogenic centrifugal circulators have been developed in order to answer to an increasing demand of 4 K refrigerators able to distribute cold power.

    We study the branching ratios, the direct CP asymmetries in $B\\to K^{(*)}\\bar{K}^{(*)}$ decays and the polarization fractions of $B\\to K^{*}\\bar{K}^{*}$ decays by employing the QCD factorization in the minimal supersymmetric standard model with R-parity violation. We derive the new upper bounds on the relevant R-parity violating couplings from the latest experimental data of $B\\to K^{(*)}\\bar{K}^{(*)}$, and some of these constraints are stronger than the existing bounds. Using the constrained parameter spaces, we predict the R-parity violating effects on the other quantities in $B\\to K^{(*)}\\bar{K}^{(*)}$ decays which have not been measured yet. We find that the R-parity violating effects on the branching ratios and the direct $CP$ asymmetries could be large, nevertheless their effects on the longitudinal polarizations of $B\\to K^{*}\\bar{K}^{*}$ decays are small. Near future experiments can test these predictions and shrink the parameter spaces.

    As the annihilation contributions play important roles in solving the puzzle of the small longitudinal polarizations in $B\\to K^* \\phi$ decays, we examine the similar effects in the decays of $B\\to K^*_{0,2}(1430) \\phi$. For the calculations on the annihilated contributions, we adopt that the form factors in $B\\to K^{(*)} \\phi$ decays are parameters determined by the observed branching ratios (BRs), polarization fractions (PFs) and relative angles in experiments and we connect the parameters between $B\\to K^*_{0(2)} \\phi$ and $B\\to K^{(*)}\\phi$ by the ansatz of correlating $\\la K^*_n(1430) \\phi| (V-A)_{\\mu}|0\\ra$ to $\\la K^{(*)} \\phi| (V-A)_{\\mu}|0\\ra$. We find that the BR of $B_d\\to K^{*0}_{0}(1430) \\phi$ is $(3.69 \\pm 0.47)\\times 10^{-6}$. By using the transition form factors of $B\\to K^*_2(1430)$ in the light-front quark model (LFQM) and the 2nd version of Isgur-Scora-Grinstein-Wise (ISGW2), we show that BR of $B_d\\to K^{*0}_{2}(1430)\\phi$ is a broad allowed value and $(1.70\\pm0.80)\\times 10^{-6}$, respect...

  7. Rapid internalization of the oncogenic K+ channel K(V10.1.

    Tobias Kohl

    Full Text Available K(V10.1 is a mammalian brain voltage-gated potassium channel whose ectopic expression outside of the brain has been proven relevant for tumor biology. Promotion of cancer cell proliferation by K(V10.1 depends largely on ion flow, but some oncogenic properties remain in the absence of ion permeation. Additionally, K(V10.1 surface populations are small compared to large intracellular pools. Control of protein turnover within cells is key to both cellular plasticity and homeostasis, and therefore we set out to analyze how endocytic trafficking participates in controlling K(V10.1 intracellular distribution and life cycle. To follow plasma membrane K(V10.1 selectively, we generated a modified channel of displaying an extracellular affinity tag for surface labeling by α-bungarotoxin. This modification only minimally affected K(V10.1 electrophysiological properties. Using a combination of microscopy and biochemistry techniques, we show that K(V10.1 is constitutively internalized involving at least two distinct pathways of endocytosis and mainly sorted to lysosomes. This occurs at a relatively fast rate. Simultaneously, recycling seems to contribute to maintain basal K(V10.1 surface levels. Brief K(V10.1 surface half-life and rapid lysosomal targeting is a relevant factor to be taken into account for potential drug delivery and targeting strategies directed against K(V10.1 on tumor cells.

  8. Experiments on Hypothesis "Fuzzy K-Means is Better than K-Means for Clustering"

    Full Text Available Clustering is one of the data mining techniques that have been around to discover business intelligence by grouping objects into clusters using a similarity measure. Clustering is an unsupervised learning process that has many utilities in real time applications in the fields of marketing, biology, libraries, insurance,city-planning, earthquake studies and document clustering. Latent trends and relationships among data objects can be unearthed using clustering algorithms. Many clustering algorithms came into existence.However, the quality of clusters has to be given paramount importance. The quality objective is to achieve highest similarity between objects of same cluster and lowest similarity between objects of different clusters. In this context, we studied two widely used clustering algorithms such as the K-Means and Fuzzy K-Means. K-Means is an exclusive clustering algorithm while the Fuzzy K-Means is an overlapping clustering algorithm. In this paper we prove the hypothesis “Fuzzy K-Means is better than K-Means for Clustering” through both literature and empirical study. We built a prototype application to demonstrate the differences between the two clustering algorithms. The experiments are made on diabetes dataset obtained from the UCI repository. The empirical results reveal that the performance of Fuzzy K-Means is better than that of K-means in terms of quality or accuracy of clusters. Thus, our empirical study proved the hypothesis “Fuzzy K-Means is better than K-Means for Clustering”

  9. Characterization of Two 20kDa-Cement Protein (cp20k) Homologues in Amphibalanus amphitrite

    The barnacle, Amphibalanus amphitrite, is a common marine fouling organism. Understanding the mechanism of barnacle adhesion will be helpful in resolving the fouling problem. Barnacle cement is thought to play a key role in barnacle attachment. Although several adult barnacle cement proteins have been identified in Megabalanus rosa, little is known about their function in barnacle settlement. In this study, two homologous 20k-cement proteins (cp20k) in Amphibalanus amphitrite, named Bamcp20k-1 and Bamcp20k-2, were characterized. The two homologues share primary sequence structure with proteins from other species including Megabalanus rosa and Fistulobalanus albicostatus. The conserved structure included repeated Cys domains and abundant charged amino acids, such as histidine. In this study we demonstrated that Bamcp20k-1 localized at the α secretory cells in the cyprid cement gland, while Bamcp20k-2 localized to the β secretory cells. The differential localizations suggest differential regulation for secretion from the secretory cells. Both Bamcp20k-1 and Bamcp20k-2 from cyprids dissolved in PBS. However, adult Bamcp20k-2, which was dominant in the basal shell of adult barnacles, was largely insoluble in PBS. Solubility increased in the presence of the reducing reagent Dithiothreitol (DTT), suggesting that the formation of disulfide bonds plays a role in Bamcp20k-2 function. In comparison, Bamcp20k-1, which was enriched in soft tissue, could not be easily detected in the shell and base by Western blot and easily dissolved in PBS. These differential solubilities and localizations indicate that Bamcp20k-1 and Bamcp20k-2 have distinct functions in barnacle cementing. © 2013 He et al.

    A (k;g)-graph is a k-regular graph with girth g. A (k;g)-cage is a (k;g)-graph with the least possible number of vertices. Let f(k;g) denote the number of vertices in a (k;g)-cage. The girth pair of a graph gives the length of a shortest odd and a shortest even cycle. A k-regular graph with girth pair (g,h) is called a (k;g,h)-graph.A (k;g,h)-cage is a (k;g,h)-graph with the least possible number of vertices. Let f(k;g,h) denote the number of vertices in a (k;g,h)-cage. In this paper, we prove the following strict inequality f(k;h-1,h)<f(k,h), k≥3, h≥4.

    The study result on insulation coordination of ± 1 000 kV and higher voltage grade ultra-high voltage (UHV) DC converter stations is presented. Aiming at the ± 1 000 kV UHVDC system, influences on arrester configuration and converter transformers insulation levels of converters 'connections are discussed based on three schemes of serial converters structure: 500 kV+500 kV scheme, 667 kVq-333 kV scheme and 400 kV+400 kV+200 kV scheme. Comparing with the 500 kV+500 kV scheme, the 667 kV+333 kV scheme cannot reduce the maximum insulation level significantly and would bring problems to valve hall layout and operation controlling. The 400 kV+ 400 kV--200 kV scheme has no economic advantage as it increases land occupation and amount of equipments. According to comprehensive comparison, the 500 kV + 500 kV scheme is recommended for ±1 000 kV UHVDC projects, and it is also suitable for higher voltage grade DC systems. According to system conditions of 1 100 kV, the switching impulse withstanding level (SIWL) of 2 100 kV and the lightning impulse withstanding level (LIWL) of 2 350 kV are feasible for ± 1 100 kV UHVDC project, judging from the insulation levels. Meanwhile, arresters with higher performance are needed.

  14. A consistent picture for large penguins in D → π + π -, K + K -

    2012-10-01

    A long-standing puzzle in charm physics is the large difference between the D 0 → K + K - and D 0 → π + π - decay rates. Recently, the LHCb and CDF collaborations reported a surprisingly large difference between the direct CP asymmetries, Δ A CP, in these two modes. We show that the two puzzles are naturally related in the Standard Model via s- and d-quark "penguin contractions". Their sum gives rise to Δ A CP, while their difference contributes to the two branching ratios with opposite sign. Assuming nominal SU(3) breaking, we perform a U-spin based fit to the D 0 → K + π -, π + K - , π + π - , K + K - decay rates, which yields large penguin contractions that naturally explain Δ A CP. Expectations for the individual CP asymmetries are also discussed.

    We have observed the decays B-->phi K and phi K^* in a sample of over 45 million B mesons collected with the BABAR detector at the PEP-II collider. The measured branching fractions are BF(B^+ --> phi K^+) = (7.7^{+1.6}_{-1.4}+/- 0.8) x 10^{-6}, BF(B^0 --> phi K^0) = (8.1^{+3.1}_{-2.5}+/- 0.8) x 10^{-6}, BF(B^+ --> phi K^{*+}) = (9.7^{+4.2}_{-3.4}+/- 1.7) x 10^{-6} and BF(B^0 --> phi K^{*0}) = (8.6^{+2.8}_{-2.4}+/- 1.1) x 10^{-6}. We also report the upper limit BF(B^+ --> phi pi^+) < 1.4 x 10^{-6}$ (90% CL).

    Radiative charmonium decays from the BESII sample of 14$\\times10^{6}$ $\\psi(2S)$-events into two different final states, $\\gamma K^+K^-$ and $\\gamma\\pi^+\\pi^-$, are analyzed. Product branching fractions for $\\psi(2S)\\to\\gamma X\\to \\gamma\\pi^+\\pi^-$, $\\gamma K^+K^-$ are given, where $X=f_2(1270)$, $f_0(1500)$, and $f_0(1710)$ in $\\pi^+\\pi^-$ and $f_2(1270)$, $f_2'(1525)$, and $f_0(1700)$ in $K^+K^-$. An angular analysis gives the ratios of the helicity projections for the $f_2(1270)$ in $\\psi(2S)\\to\\gamma f_2(1270)\\to\\gamma\\pi^+\\pi^-$.

  17. PTAS for k-tour cover problem on the plane for moderately large values of k

    DEFF Research Database (Denmark)

    Adamaszek, Anna; Czumaj, Artur; Lingas, Andrzej

    2009-01-01

    Let P be a set of n points in the Euclidean plane and let O be the origin point in the plane. In the k-tour cover problem (called frequently the capacitated vehicle routing problem), the goal is to minimize the total length of tours that cover all points in P, such that each tour starts and ends...... in O and covers at most k points from P. The k-tour cover problem is known to be NP-hard. It is also known to admit constant factor approximation algorithms for all values of k and even a polynomial-time approximation scheme (PTAS) for small values of k, i.e., k=O(log n / log log n). We significantly...

  18. K2 Microlensing and Campaign 9

    Science.gov (United States)

    Penny, Matthew

    2016-06-01

    Campaign 9 of K2 will observe a contiguous 3.7 deg^2 region of the Galactic bulge in order to search for microlensing events and measure microlens parallaxes. It will also perform targeted follow-up of approximately 50 microlensing events spread throughout the Kepler focal plane. Parallax measurements are a critical ingredient for measurements of both the lens mass and distance, which contribute to our understanding of the formation of cold exoplanets, and the formation of planets as a function of Galactic environment. Additionally, as the first un-targeted, space-based microlensing survey, K2C9 offers us the first chance to measure the masses and kinematics of a large population of free-floating planet candidates, whose large abundance has been a puzzle since their discovery.I will review the scientific goals of the K2C9 survey, which will be well underway, and report on the ongoing activity of the K2 Campaign 9 Microlensing Science Team and the wider microlensing community, with a focus on the progress that has been made towards analyzing K2 data in crowded fields.

  19. k-Connectivity of Random Key Graphs

    CERN Document Server

    Zhao, Jun; Gligor, Virgil

    2015-01-01

    Random key graphs represent topologies of secure wireless sensor networks that apply the seminal Eschenauer-Gligor random key predistribution scheme to secure communication between sensors. These graphs have received much attention and also been used in diverse application areas beyond secure sensor networks; e.g., cryptanalysis, social networks, and recommender systems. Formally, a random key graph with $n$ nodes is constructed by assigning each node $X_n$ keys selected uniformly at random from a pool of $Y_n$ keys and then putting an undirected edge between any two nodes sharing at least one key. Considerable progress has been made in the literature to analyze connectivity and $k$-connectivity of random key graphs, where $k$-connectivity of a graph ensures connectivity even after the removal of $k$ nodes or $k$ edges. Yet, it still remains an open question for $k$-connectivity in random key graphs under $X_n \\geq 2$ and $X_n = o(\\sqrt{\\ln n})$ (the case of $X_n=1$ is trivial). In this paper, we answer the a...

    Superconducting magnets of toroidal field (TF) and poloidal field (PF) of HT-7U tokamak are all made of NbTi/Cu Cable-in-Conduit Conductor (CICC), and cooled with a forced flow supercritical helium of 3.8 K. A helium refrigerator with an equivalent capacity of 2 kW/4 K will be constructed. This paper presents the design of the helium refrigerator process, the thermodynamics of the refrigeration cycle and the refrigerator equipments.

  2. Determining the Theta(+) quantum numbers through the K+ p -> pi(+)K(+)n reaction

    OpenAIRE

    Hyodo, T; Hosaka, Atsushi; Oset Báguena, Eulogio

    2004-01-01

    We study the $K^+p\\to \\pi^+K^+n$ reaction with some kinematics suited to the production of the $\\Theta^+$ resonance recently observed. We show that, independently of the quantum numbers of the $\\Theta^+$, a resonance signal is always observed in the $K^+$ forward direction. In addition, we also show how a combined consideration of the strength at the peak, and the angular dependence of polarization observables can help determine the $\\Theta^+$ quantum numbers using the present reaction.

However, no evidence for an exotic baryon near 1540~MeV/$c^2$, denoted as $\\Theta(1540)^0$~($\\bar{\\Theta}~(1540)^0$) or $\\Theta(1540)^{++}$~($\\Theta(1540)^{--}$), is seen in the $p K^-$~($\\bar{p}K^+$) or $pK^+$~($\\bar{p} K^-$) invariant mass spectra.

  7. S-wave K- pi+ system in D+ ---> K- pi+ pi+ decays from Fermilab E791

    Energy Technology Data Exchange (ETDEWEB)

    Meadows, B.T.; /Cincinnati U.

    2005-06-01

    A new approach to the analysis of three body decays is presented. Model-independent results are obtained for the S-wave K{pi} amplitude as a function of K{pi} invariant mass. These are compared with results from K{sup -}{pi}{sup +} elastic scattering, and the prediction of the Watson theorem, that the phase behavior be the same below K{eta}' threshold, is tested. Contributions from I = 1/2 and I = 3/2 are not resolved in this study. If I = 1/2 dominates, however, the Watson theorem does not describe these data well.

    A measurement of the effective $B^0_s \\rightarrow K^+K^-$ lifetime is presented using approximately $37 pb^{-1}$ of data collected by LHCb during 2010. This quantity can be used to put constraints on contributions from processes beyond the Standard Model in the $B_s$ meson system and is determined by two complementary approaches as $\\tau_{B_s\\to K^+K^-} = 1.440 \\pm 0.096 (stat) \\pm 0.008 (syst) \\pm 0.003 (model) ps$.

  10. Body K and 40K in Chinese subjects measured with a whole-body counter

    International Nuclear Information System (INIS)

    More than 380 Chinese adults of both sexes were studied for their total body K and 40K using the National Tsing Hua University whole-body counter. The K values were found to have an average of 1.75 ± 0.4 g K kg-1 body weight for males and 1.41 ± 0.1 g K kg-1 body weight for females. The average K value for both sexes was 1.69 ± 0.4 g K kg-1 body weight. The annual absorbed dose for the average male was calculated to be 0.21 ± 0.04 mGy and for the average female was 0.17 ± 0.01 mGy. The average for both sexes was 0.20 ± 0.04 mGy. The 40K activity per unit body weight varied inversely with slenderness, and total body K varied directly with body-build index

    We present the first study of the vector (Wess-Zumino) current in tau(-)-->K-pi-K+nu(tau) decay using data collected with the CLEO III detector at the Cornell Electron Storage Ring. We determine the quantitative contributions to the decay width from the vector and axial vector currents. Within the framework of a model by Kühn and Mirkes, we identify the quantitative contributions to the total decay rate from the intermediate states omegapi, rho(')pi, and K*K. PMID:15245150

  12. Development and test of a 100 kVA superconducting transformer operated at 77 K

    International Nuclear Information System (INIS)

    High-temperature superconducting (HTS) transformers are very promising candidates for application in electrical power engineering. Their main advantages are reduced size, weight, better efficiency and reduced potential fire and environmental hazards. We have designed, constructed and tested a 100 kVA HTS power transformer operated at 77 K. The nominal primary and secondary currents (voltages) are 18 A (5.6 kV) and 92 A (1.1 kV), respectively. No-load tests, short-circuit tests and load tests proved repeatedly that the transformer has the rated capacity. HTS winding losses of 20.6 W and iron losses of 403 W were measured. (author)

  13. On the algebraic K-theory of the complex K-theory spectrum

    2010-03-01

    Let p>3 be a prime, let ku be the connective complex K-theory spectrum, and let K(ku) be the algebraic K-theory spectrum of ku. We study the p-primary homotopy type of the spectrum K(ku) by computing its mod (p,v_1) homotopy groups. We show that up to a finite summand, these groups form a finitely generated free module over a polynomial algebra F_p[b], where b is a class of degree 2p+2 defined as a higher Bott element.

    Single crystals of K8(K5F)U6Si8O40 were grown from a mixed alkali halide flux. K8(K5F)U6Si8O40 is the first intergrowth uranyl silicate, being composed of alternating slabs related to two previously reported uranyl silicates: Cs2USiO6 and [Na9F2][(UO2)(UO2)2(Si2O7)2]. It exhibits intense luminescence, which is influenced by the [(UO2)2O] dimers present in the structure. PMID:26974872

    The decay $B_c^+ \\rightarrow J/\\psi K^+ K^- \\pi^+$ is observed for the first time, using proton-proton collisions collected with the LHCb detector corresponding to an integrated luminosity of 3 fb$^{-1}$. A signal yield of 78$\\pm$14 decays is reported with a significance of 6.2 standard deviations. The ratio of the branching fraction of $B_c^+ \\rightarrow J/\\psi K^+ K^- \\pi^+$ decays to that of $B_c^+ \\rightarrow J/\\psi \\pi^+$ decays is measured to be $0.53\\pm 0.10\\pm0.05$, where the first uncertainty is statistical and the second is systematic.

    The heavy Z' boson with family nonuniversal couplings can introduce flavour changing effects. Constraints on nondiagonal Z' couplings coming from the \\mu-e conversion in a muonic atom, K^0 - \\bar{K^0} and B - \\bar{B} mixing, epsilon and epsilon'/ \\epsilon CP- violating coefficients have been already established. By using the OPAL upper bound of the branching ratio for the B^- -> K^- K^- \\pi^+ decay, we indicate additional constraints on the Z' couplings. We comment also on the constraints of ...

    High resolution studies of a0/f0(980) decays into channels involving open strangeness are currently being performed at COSY-Jfilich.As a "filter" for isospin-zero intermediate states,i.e.to selectively produce the fo(980) resonance,the dd→αK+K- reaction was measured with the magnetic ANKE spectrometer.In order to determine the luminosity of this experiment,the elastically and quasi-elastically scattered deuterons were recorded simultaneously with the αK + K- events.Here we report about the luminosity determination via investigating the (quasi-) elastic deuterons at ANKE.

    2003-01-01

    In the on-going evolution of GaAs Quantum Well Infrared Photodetectors (QWIPs) we have developed a 1,024 x 1,024 (1K x1K), 8.4-9 microns infrared focal plane array (FPA). This 1 megapixel detector array is a hybrid using the Rockwell TCM 8050 silicon readout integrated circuit (ROIC) bump bonded to a GaAs QWIP array fabricated jointly by engineers at the Goddard Space Flight Center (GSFC) and the Army Research Laboratory (ARL). The finished hybrid is thinned at the Jet Propulsion Lab. Prior to this development the largest format array was a 512 x 640 FPA. We have integrated the 1K x 1K array into an imaging camera system and performed tests over the 40K-90K temperature range achieving BLIP performance at an operating temperature of 76K (f/2 camera system). The GaAs array is relatively easy to fabricate once the superlattice structure of the quantum wells has been defined and grown. The overall arrays costs are currently dominated by the costs associated with the silicon readout since the GaAs array fabrication is based on high yield, well-established GaAs processing capabilities. In this paper we will present the first results of our 1K x 1K QWIP array development including fabrication methodology, test data and our imaging results.

    2008-01-01

    We investigate charged and neutral current neutrino induced incoherent pion production off nuclei at MiniBooNE and K2K energies within the GiBUU model. We assume impulse approximation and treat the nucleus as a local Fermi gas of nucleons bound in a mean-field potential. In-medium spectral functions are also taken into account. The outcome of the initial neutrino nucleon reaction undergoes complex hadronic final state interactions. We present results for neutral current pi^0 and charged current pi^+ production and compare to MiniBooNE and K2K data.

    2014-01-01

    The history of the discovery and development of vitamin K and its antagonists, the oral anticoagulants dicoumarol and warfarin, are fascinating, triumphant landmarks in the annals of medicine. Vitamin K was found by Carl Peter Henrik Dam and Fritz Schønheyder from the University of Copenhagen....... The discovery was initiated by Dam, by a lucky choice of chicks in the dissertation of sterol metabolism, since the vitamin is not formed by intestinal bacteria in these animals. In these experiments the lack of an unknown factor in the synthetic diet caused internal bleeding similar to that found in scurvy......, but the bleeding was not reversed by vitamin C and it could not be explained by the lack of classical vitamins. In 1935 the unknown antihaemorrhagic factor was named vitamin K and a few months later the phenomenon was also observed by H.J. Almquist and E.L.R. Stokstad in Berkeley. The activity of the factor...

  3. Light gauge boson in rare $K$ decay

    CERN Document Server

    Chen, Chuan-Hung

    2016-01-01

    The inconsistent conclusions for a light gauge boson $X$ production in the $K^- \\to \\pi^- X$ exist in the literature. It is found that the process can be generated by the tree-level $W$-boson annihilation and loop-induced $s\\to dX$. We find that it strongly depends on the $SU(3)$ limit or the unique gauge coupling to the quarks, whether the $K^-\\to \\pi^- X$ decay, which is from the $W$-boson annihilation, is suppressed by $m^2_X \\epsilon_X \\cdot p_K$; however, no such suppression is found via the loop-induced $s\\to d X$. The constraints on the relevant couplings are studied.

  4. k-Strings as Fundamental Strings

    CERN Document Server

    Giataganas, Dimitrios

    2015-01-01

    It has been noticed that the k-string observables can be expressed in terms of the fundamental string ones. We identify a sufficient condition for a generic gravity dual background which when satisfied the mapping can be done. The condition is naturally related to a preserved quantity under the T-dualities acting on the Dp-brane describing the high representation Wilson loops. We also find the explicit relation between the observables of the heavy k-quark and the single quark states. As an application to our generic study and motivated by the fact that the anisotropic theories satisfy our condition, we compute the width of the k-string in these theories to find that the logarithmic broadening is still present, but the total result is affected by the anisotropy of the space.

    Fränzel, Benjamin; Fischer, Frank; Steegborn, Clemens; Wolters, Dirk Andreas

    2015-01-01

    Acetylation is a common PTM of proteins but is still challenging to analyze. Only few acetylome studies have been performed to tackle this issue. Yet, the detection of acetylated proteins in complex cell lysates remains to be improved. Here, we present a proteomic approach with proteinase K as a suitable protease to identify acetylated peptides quantitatively. We first optimized the digestion conditions using an artificial system of purified bovine histones to find the optimal protease. Subsequently, the capability of proteinase K was demonstrated in complex HEK293 cell lysates. Finally, SILAC in combination with MudPIT was used to show that quantification with proteinase K is possible. In this study, we identified a sheer number of 557 unique acetylated peptides originating from 633 acetylation sites.

    2012-01-01

    It is well documented that the KRAS oncogene efficiently transforms non-malignant cells,and there is some evidence for the role of mitochondria in this process.Now Peng Huang and colleagues show that K-Ras induction results early on in mitochondria assuming the phenotype consistent with the so-called Warburg effect,i.e.,increased glycolysis and attenuated oxidative phosphorylation.Thus the K-Ras protein capable of swift induction of phenotypic changes typical of cancer cells,yet these changes are reversible,and for cells to irreversibly reach their full malignant potential a much longer K-Ras expression is required,implicating mitochondria in the longer-term effects of the oncogene.

    2015-01-01

    Full Text Available A 21-year-old primigravida had a pregnancy complicated by hyperemesis gravidarum (HG beginning at 7-week gestation. Despite medical therapy, she lost 18% of her prepregnancy weight. Early ultrasound at 14 weeks demonstrated a flattened facial profile with nasal hypoplasia (Binder phenotype consistent with vitamin K deficiency from HG. She had a percutaneous endoscopic gastrojejunostomy tube placed for enteral feeding at 15-week gestation. At repeated anatomy ultrasound at 21-week gestation, delivery, and postnatal pediatric genetics exam, nasal hypoplasia was consistent with vitamin K deficiency embryopathy from HG. Nausea and vomiting of pregnancy is a common condition. HG, the most severe form, has many maternal and fetal effects. Evaluation of vitamin K status could potentially prevent this rare and disfiguring embryopathy.

    2006-01-01

    The thermal fatigue behavior of K465 superalloy was investigated at the peak temperature of 1050℃. By scanning electron microscopy (SEM) and optical microscopy, the main crack length was observed and measured. The initiation sites of the tested alloys are different in as-cast (named as K465) and solution heat treatment (named as SK465) conditions.In K465 alloy, most thermal fatigue cracks nucleate at (Nb,W,Ti)C carbides. In SK465 alloy, thermal fatigue cracks initiate in interdendritic regions, MC-type carbides and some interfaces. Thermal fatigue cracks propagate in transdendritic mode,and M6C-type carbides could retard thermal fatigue crack growth for SK465 superalloy.

  11. Weak decays of K and π mesons

    International Nuclear Information System (INIS)

    Through a special interplay of strong and weak interactions, small but significant pieces with a ''wrong'' flavor could be introduced into wave functions of mesons. Thus, e.g., not only a (u bar s) pair, but also a (u bar d) pair can be found with some probability within K+, etc. The possible importance of such ''anomalous'' terms in understanding of K-meson decays is discussed in a new scheme. The scheme is characterized by diagrammatic calculations of full amplitudes in the long-distance environment. Two classes of models which correctly reproduce the main K-meson branching ratios and the ΔI=1/2 rule are constructed. The predictive power of the scheme is then tested in a decay of a kaon into a pion and a light hyperphoton

    Full Text Available Aim: To report clinical experience and the comparative value of axial and instantaneous topography data in fitting Rose-K design contact lenses in moderate and severe keratoconus. Materials and Methods: Thirty-eight eyes (of 23 patients with keratoconus were fitted with Rose-K design contact lenses and followed up for at least six months or more. Visual acuity with habitual vision correction available was measured. Axial and instantaneous topography maps for each eye were recorded. Contact lens wear comfort was graded on a ten point rating scale every three months. Results: Fourteen (100% moderate keratoconus eyes (average Sim K 48.61 ± 1.24D and 23 of 24 (96% of severe keratoconus eyes (average Sim K 60.88 ± 5.31D were successfully fitted with the Rose-K lenses. Final fit contact lenses in severe keratoconus had statistically significant steeper base curves compared to average axial corneal curvature than in moderate keratoconus eyes. Average simulated corneal curvature on axial maps predicted final fit contact lens base curves significantly better than on instantaneous maps. Thirty-three of the 37 eyes fitted with contact lenses maintained wear comfort over average follow up period of 13 ± 3.5 months. Conclusions: Rose-K design rigid contact lenses are successful in visually rehabilitating 100% of moderate and 96% of severe keratoconus eyes. Most patients (90% maintained contact lens wear comfort. Corneal curvature on axial maps is a better predictive of base curve of final fit contact lens.

    any topological space with at most four points has projective dimension 2 or less. We observe that this implies a universal coefficient theorem for rational equivariant KK-theory over these spaces. As a contrasting example, we find a separable C∗dash-algebra in the bootstrap class over a certain five......-point space, the filtrated K-theory of which has projective dimension 3. Finally, as an application of our investigations, we exhibit Cuntz-Krieger algebras which have projective dimension 2 in filtrated K-theory over their respective primitive spectrum....

    Science.gov (United States)

    Lambert, N.; Barbanera, S.; Zimmerman, J. E.

    The construction of a low power cryocooler consisting of a five-stage plastic Stirling cooler with an additional Joule-Thomson stage is described. Among its novel features are a contamination-free, pneumatic helium compressor and displacer drive. Valve timing is under computer control. Titanium foil embedded in the cylinder wall reduces helium diffusion through the plastic. The Joule-Thomson stage uses the same low pressure helium as the Stirling stages. The Stirling system cools down below 9 K. The Joule-Thomson stage delivers a few mW cooling at 4.2 K.

  16. The B -> pi K Puzzle: 2009 Update

    Baek, Seungwon; Chiang, Cheng-Wei; London, David

    2009-01-01

    The measurements of B -> pi K decays have been in disagreement with the predictions of the Standard Model (SM) for some time. In this paper, we perform an update of this puzzle using the latest (2008) data. We find that the situation has become far less clear. A fit to the B -> pi K data alone suggests the presence of new physics (NP). Indeed, if one adds a constraint on the weak phase gamma coming from independent measurements -- the SM fit -- one finds that the fit is poor. On the other han...

    2005-01-01

    We calculate the important next-to-leading-order contributions to the B -> pi K, pi pi decays from the vertex corrections, the quark loops, and the magnetic penguins in the perturbative QCD approach. It is found that the latter two reduce the leading-order penguin amplitudes by about 10%, and modify only the B -> pi K branching ratios. The main effect of the vertex corrections is to increase the small color-suppressed tree amplitude by a factor of 3, which then resolves the large difference b...

    The K3 sigma model based on the -orbifold of the D 4-torus theory is studied. It is shown that it has an equivalent description in terms of twelve free Majorana fermions, or as a rational conformal field theory based on the affine algebra . By combining these different viewpoints we show that the = (4 , 4) preserving symmetries of this theory are described by the discrete symmetry group : . This model therefore accounts for one of the largest maximal symmetry groups of K3 sigma models. The symmetry group involves also generators that, from the orbifold point of view, map untwisted and twisted sector states into one another.

    We study semileptonic B meson decays B to K_1(1270) l^+ l^- and K_1(1400) l^+ l^- (l=e, mu, tau), where the strange P-wave mesons, K_1(1270) and K_1(1400), are the mixtures of the K_{1A} and K_{1B}, which are the 1^3P_1 and 1^1P_1 states, respectively. We show that the ratio R_l = Br(B to K_1(1400) l^+ l^-)/Br(B to K_1(1270) l^+ l^-), insensitive to new-physics parameters, is suitable for determining the K_1(1270)-K_1(1400) mixing angle, theta_{K_1}. The forward-backward asymmetry shows a weak theta_{K_1}-dependence for B to K_1(1270) mu^+ mu^-, but relatively strong for B to K_1(1400) mu^+ mu^-. We investigate model-independent new-physics corrections to operators relevant to the b to s l^+ l^- electroweak-penguin and weak-box diagrams. Furthermore, for the B to K_1(1270) mu^+ mu^- decay the position of the forward-backward asymmetry zero, which is almost independent of the value of theta_{K_1}, can be dramatically changed under variation of new-physics parameters.

    The activities of {sup 228}Ra in natural waters were determined by the Cherenkov counting of the daughter nuclide {sup 228}Ac. The radium was pre-concentrated on MnO{sub 2} and the radium purified via ion exchange and, after a 2-day period of incubation to allow for secular equilibrium between the parent-daughter {sup 228}Ra({sup 228}Ac), the daughter nuclide {sup 228}Ac was isolated by ion exchange according to the method of Nour et al. [2004. Radium-228 determination of natural waters via concentration on manganese dioxide and separation using Diphonix ion exchange resin. Appl. Radiat. Isot. 61, 1173-1178]. The Cherenkov photons produced by {sup 228}Ac were counted directly without the addition of any scintillation reagents. The optimum Cherenkov counting window, sample volume, and vial type were determined experimentally to achieve optimum Cherenkov photon detection efficiency and lowest background count rates. An optimum detection efficiency of 10.9{+-}0.1% was measured for {sup 228}Ac by Cherenkov counting with a very low Cherenkov photon background of 0.317{+-}0.013 cpm. The addition of sodium salicylate into the sample counting vial at a concentration of 0.1 g/mL yielded a more than 3-fold increase in the Cherenkov detection efficiency of {sup 228}Ac to 38%. Tests of the Cherenkov counting technique were conducted with several water standards of known activity and the results obtained compared closely with a conventional liquid scintillation counting technique. The advantages and disadvantages of Cherenkov counting compared to liquid scintillation counting methods are discussed. Advantages include much lower Cherenkov background count rates and consequently lower minimal detectable activities for {sup 228}Ra and no need for expensive environmentally unfriendly liquid scintillation cocktails. The disadvantages of the Cherenkov counting method include the need to measure {sup 228}Ac Cherenkov photon detection efficiency and optimum Cherenkov counting volume, which are not at all required when liquid scintillation analysis is used.

The radium was pre-concentrated on MnO(2) and the radium purified via ion exchange and, after a 2-day period of incubation to allow for secular equilibrium between the parent-daughter (228)Ra((228)Ac), the daughter nuclide (228)Ac was isolated by ion exchange according to the method of Nour et al. [2004. Radium-228 determination of natural waters via concentration on manganese dioxide and separation using Diphonix ion exchange resin. Appl. Radiat. Isot. 61, 1173-1178]. The Cherenkov photons produced by (228)Ac were counted directly without the addition of any scintillation reagents. The optimum Cherenkov counting window, sample volume, and vial type were determined experimentally to achieve optimum Cherenkov photon detection efficiency and lowest background count rates. An optimum detection efficiency of 10.9+/-0.1% was measured for (228)Ac by Cherenkov counting with a very low Cherenkov photon background of 0.317+/-0.013cpm. The addition of sodium salicylate into the sample counting vial at a concentration of 0.1g/mL yielded a more than 3-fold increase in the Cherenkov detection efficiency of (228)Ac to 38%. Tests of the Cherenkov counting technique were conducted with several water standards of known activity and the results obtained compared closely with a conventional liquid scintillation counting technique. The advantages and disadvantages of Cherenkov counting compared to liquid scintillation counting methods are discussed. Advantages include much lower Cherenkov background count rates and consequently lower minimal detectable activities for (228)Ra and no need for expensive environmentally unfriendly liquid scintillation cocktails. The disadvantages of the Cherenkov counting method include the need to measure (228)Ac Cherenkov photon detection efficiency and optimum Cherenkov counting volume, which are not at all required when liquid scintillation analysis is used.

  10. Actinium: A RESTful Runtime Container for Scriptable Internet of Things Applications

    Programming Internet of Things (IoT) applications is challenging because developers have to be knowledgeable in various technical domains, from low-power networking, over embedded operating systems, to distributed algorithms. Hence, it will be challenging to find enough experts to provide software for the vast number of expected devices, which must also be scalable and particularly safe due to the connection to the physical world. To remedy this situation, we propose an architecture that pr...

  11. Reflection asymmetry in odd-A and odd-odd actinium nuclei

    International Nuclear Information System (INIS)

    Theoretical calculations and measurements indicate that octupole correlations are at a maximum in the ground states of the odd-proton nuclei Ac and Pa. It has been expected that odd-odd nuclei should have even larger amount of octupole-octupole correlations. We have recently made measurements on the structure of 224Ac. Although spin and parity assignments could not be made, two bands starting at 354.1 and 360.0 keV have properties characteristic of reflection asymmetric shape. These two bands have very similar rotational constants and also similar alpha decay rates, which suggest similarity between the wavefunctions of these bands. These signatures provide evidence for octupole correlations in these nuclides

  13. New method for large scale production of medically applicable Actinium-225 and Radium-223

    International Nuclear Information System (INIS)

    Alpha-emitters (211At, 212Bi, 213Bi, 223Ra, 225Ac) are promising for targeted radiotherapy of cancer. Only two alpha decays near a cell membrane result in 50% death of cancer cell and only a single decay inside the cell is required for this. 225Ac may be used either directly or as a mother radionuclide in 213Bi isotope generator. Production of 225Ac is provided by three main suppliers - Institute for Transuranium Elements in Germany, Oak Ridge National Laboratory in USA and Institute of Physics and Power Engineering in Obninsk, Russia. The current worldwide production of 225Ac is approximately 1.7 Ci per year that corresponds to only 100-200 patients that could be treated annually. The common approach for 225Ac production is separation from mother 229Th or irradiation of 226Ra with protons in a cyclotron. Both the methods have some practical limitations to be applied routinely. 225Ac can be also produced by irradiation of natural thorium with medium energy protons . Cumulative cross sections of 225Ac, 227Ac, 227Th, 228Th formations have been obtained recently. Thorium targets (1-9 g) were irradiated by 114-91 MeV proton beam (1-50 μA) at INR linear accelerator. After dissolution in 8 M HNO3 + 0.004 M HF thorium was removed by double LLX by HDEHP in toluene (1:1). Ac and REE were pre-concentrated and separated from Ra and most fission products by DGA-Resin (Triskem). After washing out by 0.01 M HNO3 Ac was separated from REE by TRU Resin (Triskem) in 3 M HNO3 media. About 6 mCi 225Ac were separated in hot cell with chemical yield 85%. The method may be upscaled for production of Ci amounts of the radionuclide. The main impurity is 227Ac (0.1% at the EOB) but it does not hinder 225Ac from being used for medical 225Ac/213Bi generators. (author)

    2016-01-01

    Context: After the loss of a second reaction wheel the Kepler mission was redesigned as the K2 mission, pointing towards the ecliptic and delivering data for new fields approximately every 80 days. The steady flow of data obtained with a reduced pointing stability calls for dedicated pipelines for extracting light curves and correcting these for use in, e.g., asteroseismic analysis. Aims: We provide corrected light curves for the K2 fields observed until now (campaigns 0-4), and provide a comparison with other pipelines for K2 data extraction/correction. Methods: Raw light curves are extracted from K2 pixel data using the "K2-pixel-photometry" (K2P$^2$) pipeline, and corrected using the KASOC filter. Results: The use of K2P$^2$ allows for the extraction of the order of 90.000 targets in addition to 70.000 targets proposed by the community - for these, other pipelines provide no data. We find that K2P$^2$ in general performs as well as, or better than, other pipelines for the tested metrics of photometric qual...

    A 275 kV-3 kA high temperature superconducting (HTS) cable has been developed in the Materials & Power Applications of Coated Conductors (M-PACC) project. AC loss reduction of a two-layer HTS conductor was undertaken by removing the edges of YBCO tapes with low critical current density. The HTS conductor using these tapes was fabricated, and low loss of 0.235 W/m at 3 kA rms was achieved. The 275 kV-3 kA cable was designed, and the 2 m model cables were fabricated. This cable had 325 mm 2 copper stranded former inside the HTS conductor and a 310 mm 2 copper shield layer on the HTS shield layer for over-current protection. These cables withstood an over-current of 63.0 kA for 0.6 s, which is the worst situation for 275 kV systems. The partial discharge (PD) and V- t characteristics of a liquid nitrogen (LN 2)/polypropylene (PP) laminated paper composite insulation system have been integrated into the design of the insulation for the 275 kV cable. The results revealed that the PD inception stress (PDIE) did not depend on the insulation thickness, and that lifetime indices of V- t characteristics at PD inception were as high as about 80-100.

    The Tokai-to-Kamioka (T2K) experiment studies neutrino oscillations using an off-axis muon neutrino beam with a peak energy of about 0.6 GeV that originates at the J-PARC accelerator facility. Interactions of the neutrinos are observed at near detectors placed at 280 m from the production target and at the far detector -- Super-Kamiokande (SK) -- located 295 km away. The flux prediction is an essential part of the successful prediction of neutrino interaction rates at the T2K detectors and is an important input to T2K neutrino oscillation and cross section measurements. A FLUKA and GEANT3 based simulation models the physical processes involved in the neutrino production, from the interaction of primary beam protons in the T2K target, to the decay of hadrons and muons that produce neutrinos. The simulation uses proton beam monitor measurements as inputs. The modeling of hadronic interactions is re-weighted using thin target hadron production data, including recent charged pion and kaon measurements from the NA...

    The Spallation Neutron Source (SNS) linear accelerator (LINAC) consists of 81 superconducting radio frequency (SRF) cavities cooled to 2.1 K by a cryogenic refrigeration system. The 2-K cold box consists of four stages of cold compressors with liquid nitrogen cooled variable speed motors. Transitioning from 4.5-K operation to 2.1-K operation in the cryomodules involves pumping the cryomodules down from approximately 1 bar to 0.040 bar. This effort is conducted through the use of several sequences developed as a collaborative effort between Thomas Jefferson National Accelerator Facility (TJNAF) and SNS personnel during the original commissioning of the SNS cryogenic system. Over the last ten years, multiple lessons have been learned about VFD behavior, thermal stability, procedural development and refining the sequences. From 2012 to 2014, there were multiple pump down iterations that were not successful. Studies have been conducted to determine the cause of these unsuccessful iterations. The results of these studies including components replaced and aspects that have not yet been solved are presented in this paper. Future plans to refine the sequence and determine the cause of unsuccessful pump downs will also be presented.

  13. kT factorization of exclusive processes

    Science.gov (United States)

    Nagashima, Makiko; Li, Hsiang-Nan

    2003-02-01

    We prove the kT factorization theorem in perturbative QCD (PQCD) for exclusive processes by considering πγ*→γ(π) and B→γ(π)lν¯. The relevant form factors are expressed as the convolution of hard amplitudes with two-parton meson wave functions in the impact parameter b space, b being conjugate to the parton transverse momenta kT. The point is that on-shell valence partons carry longitudinal momenta initially, and acquire kT through collinear gluon exchanges. The b-dependent two-parton wave functions with an appropriate path for the Wilson links are gauge-invariant. The hard amplitudes, defined as the difference between the parton-level diagrams of on-shell external particles and their collinear approximation, are also gauge-invariant. We compare the predictions for two-body nonleptonic B meson decays derived from kT factorization (the PQCD approach) and from collinear factorization (the QCD factorization approach).

    We restrict purely kinetic k-essence. Assuming that the equation of state is a power law of the kinetic energy, I.e. W = w0Xα, we find that a must be positive to obtain accelerated phases, constrained from the conditions for stability and causality. In this case the k-essence behaves like a phantom. We also study the evolutions of the equation of state and the speed of sound with numerical simulations.%We restrict purely kinetic k-essence.Assuming that the equation of state is a power law of the kinetic energy,i.e.ω =ω0Xα,we find that α must be positive to obtain accelerated phases,constrained from the conditions for stability and causality.In this case the k-essence behaves like a phantom.We also study the evolutions of the equation of state and the speed of sound with numerical simulations.In the last decade a convergence of independent cosmological observations have suggested that the Universe is experiencing accelerated expansion.An unknown energy component,dubbed as dark energy,has been proposed to explain this acceleration.

  8. K-mouflaging Clusters of Galaxies

    CERN Document Server

    Brax, Philippe; Valageas, Patrick

    2015-01-01

    We investigate the effects of a K-mouflage modification of gravity on the dynamics of clusters of galaxies. We extend the description of K-mouflage to situations where the scalar field responsible for the modification of gravity is coupled to a perfect fluid with pressure. We describe the coupled system at both the background cosmology and cosmological perturbations levels, focusing on cases where the pressure emanates from small-scale nonlinear physics. We derive these properties in both the Einstein and Jordan frames, as these two frames already differ by a few percents at the background level for K-mouflage scenarios, and next compute cluster properties in the Jordan frame that is better suited to these observations. Galaxy clusters are not screened by the K-mouflage mechanism and therefore feel the modification of gravity in a maximal way. This implies that the halo mass function deviates from $\\Lambda$-CDM by a factor of order one for masses $M\\gtrsim 10^{14} \\ h^{-1} M_\\odot$. We then consider the hydro...
