Abstract: We present a search for WW and WZ production in final states that contain a charged lepton (electron or muon) and at least two jets, produced in {radical}(s)=1.96 TeV pp collisions at the Fermilab Tevatron, using data corresponding to 1.2 fb{sup -1} of integrated luminosity collected with the CDF II detector. Diboson production in this decay channel has yet to be observed at hadron colliders due to the large single W plus jets background. An artificial neural network has been developed to increase signal sensitivity, as compared with an event selection based on conventional cuts. We set a 95% confidence level upper limit of {sigma}{sub WW}xBR(W{yields}l{nu}{sub l},W{yields}jets)+{sigma}{sub WZ}xBR(W{yields}l{nu}{sub l},Z{yields}jets)

Abstract: Aim: The aim of the present study was to evaluate the reliability of reconstructing composite defects of the mandible with a local pedicled mandibular osteomuscular flap. Materials and methods: A retrospective study examined patients undergoing secondary mandibular reconstruction following tumour ablation using local pedicled mandibular osteomuscular flaps. The study included five men and three women. The segmental defects of the mandible resulted from oral carcinoma in five cases and mandibular ameloblastoma in three. Results: All of the flaps survived. Proper aesthetics and complete functionality were obtained, and no donor-site problems occurred. The patients were followed for 16–24 months and no recurrence was seen. Conclusions: The pedicled mandibular osteomuscular flap is technically simple, fast to harvest, and has an exceptionally long arc of rotation, which enables the reconstruction of composite segmental defects of the mandible following tumour ablation.

Abstract: This Letter describes the current most precise measurement of the W boson pair production cross section and most sensitive test of anomalous WW{gamma} and WWZ couplings in p{bar p} collisions at a center-of-mass energy of 1.96 TeV. The WW candidates are reconstructed from decays containing two charged leptons and two neutrinos, where the charged leptons are either electrons or muons. Using data collected by the CDF II detector from 3.6 fb{sup -1} of integrated luminosity, a total of 654 candidate events are observed with an expected background contribution of 320 {+-} 47 events. The measured total cross section is {sigma}(p{bar p} {yields} W{sup +}W{sup -} + X) = 12.1 {+-} 0.9 (stat){sub -1.4}{sup +1.6} (syst) pb, which is in good agreement with the standard model prediction. The same data sample is used to place constraints on anomalous WW{gamma} and WWZ couplings.

Abstract: Background Acute Pain Services (APS) were introduced primarily to improve postoperative pain management. Although pain is similar in prevalence and severity in medical and surgical wards, its assessment and management in non-surgical patients often receives less attention and resources. Objective To investigate the extent of APS involvement on medical wards and obtain perceptions of deficiencies. Method A questionnaire was mailed to APS leads in 287 UK NHS hospitals; 229 questionnaires were returned (79.8% response). Results Only 36 (16%) of the 225 hospitals with medical wards reported routine APS involvement. Pain scores were not recorded in 75 (33%) hospitals, 11 (5%) denied knowledge about assessments being conducted, and 185 (82.2%) respondents felt that pain management on medical wards was inadequate. Conclusions Perceived lack of training and awareness of healthcare staff were highly ranked contributing factors, and this was attributed to inadequate funding. This study highlights the scope for improvement of pain control in medical patients, with benefits from reduced morbidity and faster recovery.

Abstract: This Letter describes the current most precise measurement of the W boson pair production cross section and most sensitive test of anomalous WWγ and WWZ couplings in pp collisions at a center-of-mass energy of 1.96 TeV. The WW candidates are reconstructed from decays containing two charged leptons and two neutrinos. Using data collected by the CDF II detector from 3.6 fb(-1) of integrated luminosity, a total of 654 candidate events are observed with an expected background of 320±47 events. The measured cross section is σ(pp→W+ W- +X)=12.1±0.9(stat)-1.4+1.6(syst) pb, which is in good agreement with the standard model prediction. The same data sample is used to place constraints on anomalous WWγ and WWZ couplings.

Abstract: We report a search for single top quark production with the CDF II detector using 2.1 fb{sup -1} of integrated luminosity of pp collisions at {radical}(s)=1.96 TeV. The data selected consist of events characterized by large energy imbalance in the transverse plane and hadronic jets, and no identified electrons and muons, so the sample is enriched in W{yields}{tau}{nu} decays. In order to suppress backgrounds, additional kinematic and topological requirements are imposed through a neural network, and at least one of the jets must be identified as a b quark jet. We measure an excess of signal-like events in agreement with the standard model prediction, but inconsistent with a model without single top quark production by 2.1 standard deviations ({sigma}), with a median expected sensitivity of 1.4{sigma}. Assuming a top quark mass of 175 GeV/c{sup 2} and ascribing the excess to single top quark production, the cross section is measured to be 4.9{sub -2.2}{sup +2.5}(stat+syst) pb, consistent with measurements performed in independent data sets and with the standard model prediction.

Abstract: Background \ud A pilot investigation was undertaken to assess the performance of a novel fiber-optic cerebral pulse oximetry system. A fiber-optic probe designed to pass through the lumen of a cranial bolt of the type used to make intracranial pressure measurements was used to obtain optical reflectance signals directly from brain tissue.\ud \ud Methods \ud Short-duration measurements were made in six patients undergoing neurosurgery. These were followed by a longer duration measurement in a patient recovering from an intracerebral hematoma. Estimations of cerebral arterial oxygen saturation derived from a frequency domain-based algorithm are compared with simultaneous pulse oximetry (SpO2) and emoximeter (SaO2) blood samples.\ud \ud Results \ud The short-duration measurements showed that reliable photoplethysmographic signals could be obtained from the brain tissue. In the long-duration study, the mean (±SD) difference between cerebral oxygen saturation (ScaO2) and finger SpO2 (in saturation units) was\ud -7.47(±3.4)%. The mean (±SD) difference between ScaO2 and blood SaO2 was -7.37(±2.8)%.\ud \ud Conclusions \ud This pilot study demonstrated that arterial oxygen saturation may be estimated from brain tissue via a fiber-optic pulse oximeter used in conjunction with a cranial bolt. Further studies are needed to confirm the clinical utility of the technique.

Abstract: We report on a search for the standard model Higgs boson produced in association with a W or Z boson in p{bar p} collisions at {radical}s = 1.96 TeV recorded by the CDF II experiment at the Tevatron in a data sample corresponding to an integrated luminosity of 2.1 fb{sup -1}. We consider events which have no identified charged leptons, an imbalance in transverse momentum, and two or three jets where at least one jet is consistent with originating from the decay of a b hadron. We find good agreement between data and predictions. We place 95% confidence level upper limits on the production cross section for several Higgs boson masses ranging from 110 GeV/c{sup 2} to 150 GeV/c{sup 2}. For a mass of 115 GeV/c{sup 2} the observed (expected) limit is 6.9 (5.6) times the standard model prediction.

Abstract: The cross section for jets from b quarks produced simultaneously with a W boson has been measured in p{bar p} collision data from 1.9 fb{sup -1} of integrated luminosity recorded by the CDF II detector at the Tevatron. Jets consistent with the decay of long-lived hadrons are selected by identifying a displaced decay vertex. The invariant mass of the charged particle tracks associated with the vertex is sensitive to the flavor of the decaying hadron and is used to determine the fraction of jets from b-quark production. We measure a b-jet cross section of 2.74 {+-} 0.27(stat.) {+-} 0.42(syst.) pb in association with one flavor of leptonic W boson decay over a limited kinematic phase space.

Abstract: We report two complementary measurements of the diboson (WW + WZ) cross section in the final state consisting of an electron or muon, missing transverse energy, and jets, performed using p{bar p} collision data at {radical}s = 1.96 TeV collected by the Collider Detector at Fermilab. The first method uses the dijet invariant mass distribution while the second method uses more of the kinematic information in the event through matrix-element calculations of the signal and background processes and has a higher sensitivity. The result from the second method has a signal significance of 5.4{sigma} and is the first observation of WW + WZ production using this signature. Combining the results from both methods gives {sigma}{sub WW+WZ} = 16.0 {+-} 3.3 pb, in agreement with the standard model prediction.

212. Reduction of high reset currents in unipolar resistance switching Pt/SrTiOx/Pt capacitors using acceptor doping

Abstract: The high reset current, IR, in unipolar resistance switching is an important issue which should be resolved for practical applications in nonvolatile memories. We showed that,during the forming and set processes, the compliance current, Icomp, can work as a crucial parameter to reduce IR. Doping with Co or Mn can significantly reduce the leakage current in capacitors made using SrTiOx film, opening a larger operation window for Icomp. By decreasing Icomp with acceptor doping, we could reduce IR in SrTiOx films by a factor of approximately 20. Our work suggests that the decrease of Icomp by carrier doping could be a viable alternative for reducing IR in unipolar resistance switching., 14 pages, 3 figures

Abstract: We report the most restrictive direct limits on masses of fourth-generation down-type quarks b{sup '}, and quarklike composite fermions (B or T{sub 5/3}), decaying promptly to tW{sup +}-. We search for a significant excess of events with two same-charge leptons (e, mu), several hadronic jets, and missing transverse energy. An analysis of data from pp collisions with an integrated luminosity of 2.7 fb{sup -1} collected with the CDF II detector at Fermilab yields no evidence for such a signal, setting mass limits m{sub b}{sup '}, m{sub B}>338 GeV/c{sup 2} and m{sub T{sub 5{sub /{sub 3}}}}>365 GeV/c{sup 2} at 95% confidence level.

Abstract: 21 páginas, 13 figuras, 6 tablas.-- PACS numbers: 12.15.-y, 13.85.-t, 14.60.-z, 14.65.Fy.-- CDF Collaboration: et al., We present three measurements of the top-quark mass in the lepton plus jets channel with approximately 1.9 fb(-1) of integrated luminosity collected with the CDF II detector using quantities with minimal dependence on the jet energy scale. One measurement exploits the transverse decay length of b-tagged jets to determine a top-quark mass of 166.9(-8.5)(+9.5)(stat) +/- 2.9(syst) GeV/c(2), and another the transverse momentum of electrons and muons from W-boson decays to determine a top-quark mass of 173.5(-8.9)(+8.8)(stat) +/- 3.8(syst) GeV/c(2). These quantities are combined in a third, simultaneous mass measurement to determine a top-quark mass of 170.7 +/- 6.3(stat) +/- 2.6(syst) GeV/c(2) ., We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

Abstract: 68 pages, 46 figures, 11 tables. Submitted to Phys. Rev. D. Removed typos from the authors' list We report the results of a study of multi-muon events produced at the Fermilab Tevatron collider and acquired with the CDF II detector using a dedicated dimuon trigger. The production cross section and kinematics of events in which both muon candidates are produced inside the beam pipe of radius 1.5 cm are successfully modeled by known processes which include heavy flavor production. In contrast, we are presently unable to fully account for the number and properties of the remaining events, in which at least one muon candidate is produced outside of the beam pipe, in terms of the same understanding of the CDF II detector, trigger, and event reconstruction.

Abstract: 7 páginas, 3 figuras, 1 tabla.-- PACS numbers: 14.80.Tt, 12.60.Nz, 13.85.Rm.-- CDF Collaboration: et al., We present a search for the technicolor particles ρT and πT in the process pp̅ →ρT→WπT at a center of mass energy of √s=1.96 TeV. The search uses a data sample corresponding to approximately 1.9 fb-1 of integrated luminosity accumulated by the CDF II detector at the Fermilab Tevatron. The event signature we consider is W→ℓν and πT→bb̅ , bc̅ or bu̅ depending on the πT charge. We select events with a single high-pT electron or muon, large missing transverse energy, and two jets. Jets corresponding to bottom quarks are identified with multiple b-tagging algorithms. The observed number of events and the invariant mass distributions are consistent with the standard model background expectations, and we exclude a region at 95% confidence level in the ρT-πT mass plane. As a result, a large fraction of the region m(ρT)=180–250 GeV/c2 and m(πT)=95–145 GeV/c2 is excluded., We thank Ken Lane for many fruitful discussions, the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

Abstract: 5 páginas.-- Open Access: This article is distributed under the terms of the Creative Commons Attribution Noncommercial License.-- et al., The European Physical Journal C—Particles and Fields—publishes scientific manuscripts of relevance to the scientific community following careful and strict peer reviewing and, whenever appropriate and necessary, through discussion with the authors, so as to optimise scientific content and style of presentation prior to publication. In some cases significant disagreement between authors and referees (and/or editors) of the journal cannot be resolved despite all efforts and best of intentions. While the journal— notwithstanding any appeals—retains the right to reject such manuscripts, the editors of this journal may decide, in cases deemed of exceptional interest and potential significance for the field, to accept the manuscript for publication, to amend it by “comments” of the editor(s) in charge and, if appropriate, by a “reply” of the authors of the commented manuscript. The present comment is on “Study of multi-muon events produced in pp¯ interactions at √s = 1.96 TeV” by T. Aaltonen et al. (the CDF Collaboration, Eur. Phys. J.

Abstract: We present measurements of the top quark mass using mT2, a variable related to the transverse mass in events with two missing particles. We use the template method applied to tt̅ dilepton events produced in pp̅ collisions at Fermilab’s Tevatron Collider and collected by the CDF detector. From a data sample corresponding to an integrated luminosity of 3.4 fb-1, we select 236 tt̅ candidate events. Using the mT2 distribution, we measure the top quark mass to be Mtop=168.0-4.0+4.8(stat)±2.9(syst) GeV/c2. By combining mT2 with the reconstructed top quark mass distributions based on a neutrino weighting method, we measure Mtop=169.3±2.7(stat)±3.2(syst) GeV/c2. This is the first application of the mT2 variable in a mass measurement at a hadron collider. We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

Abstract: SYNOPSIS Nodes from young field-grown coppice regrowth and branches of a mature tree of Eucalyptus radiata ssp. radiata were cultured on a MS medium containing BA and NAA. BA at 0,5 mg/l and NAA at 0,01-0,1 mg/l were most effective in promoting axillary shoot proliferation from both coppice and adult tissue. BA concentration of the medium was reduced (0,1 mg/l) to induce axial growth in regenerated bud primordia. 50–70 shoots could be obtained from one nodal culture. Multiplication rate was higher from the mature tree than from the coppice shoots. Rooting was achieved from shoot cultures on half strength MS salts supplemented with 2,5 mg/l of IBA for mature shoots and 5 mg/l for coppice shoots. The percentage of rooting of coppice shoots (90%) was much higher than for mature shoots (35%). Summer was the best season to take explant material for shoot multiplication.

Abstract: A sedimentation study of suspensions of attapulgite clay in aqueous solutions of polyvinyl alcohol (PVOH) as well as in water was conducted. The results demonstrate that PVOH can be used to control the stability of clay suspensions with respect to sedimentation. While the settling of solid particulates is significantly hindered by the formation of a network structure of clay particles, the adsorption of PVOH disrupts this structure and promotes the settling of solids. The latter effect also serves to lower the system viscosity or permit an increase of solid loading for the same viscosity level; this was quantitatively examined. The results indicate that solid volume fraction, polymer concentration, and polymer molecular weight can be adjusted to yield any desired system rheology and sedimentation stability.

Abstract: We present the results of a search for Higgs bosons predicted in two-Higgs-doublet models, in the case where the Higgs bosons decay to tau lepton pairs, using 1.8 fb{sup -1} of integrated luminosity of p{bar p} collisions recorded by the CDF II experiment at the Fermilab Tevatron. Studying the mass distribution in events where one or both tau leptons decay leptonically, no evidence for a Higgs boson signal is observed. The result is used to infer exclusion limits in the two-dimensional space of tan {beta} versus m{sub A} (the ratio of the vaccum expectation values of the two Higgs doublets and the mass of the pseudoscalar boson, respectively).

Abstract: We present an analysis of the mass of the X(3872) reconstructed via its decay to J/psi pi(+)pi(-) using 2.4 fb(-1) of integrated luminosity from p (p) over bar collisions at root s = 1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. The possible existence of two nearby mass states is investigated. Within the limits of our experimental resolution the data are consistent with a single state, and having no evidence for two states we set upper limits on the mass difference between two hypothetical states for different assumed ratios of contributions to the observed peak. For equal contributions, the 95% confidence level upper limit on the mass difference is 3.6 MeV/c(2). Under the single-state model the X(3872) mass is measured to be 3871.61 +/- 0.16(stat) +/- 0.19(syst) MeV/c(2), which is the most precise determination to date.

Abstract: We report on a search for the process $p\bar{p}\to \gamma+W/Z$ with $W/Z\to q\bar{q}$ in events containing two jets and a photon at the center-of-mass energy $\sqrt{s}=1.96$ TeV, using 184 pb$^{-1}$ of data collected by the CDF II detector. A neural network event selection has been developed to optimize the rejection of the large QCD production background; it is shown that this method gives a significant improvement in both signal-to-noise ratio and signal sensitivity, as compared with an event selection based on conventional cuts. An upper limit is presented for the $\gamma+W/Z$ production cross section with the $W$ and $Z$ decaying hadronically.

Abstract: We report on the first direct search for charged Higgs bosons in decays of top quarks in p{bar p} collisions at {radical}s = 1.96 TeV. The search uses a data sample corresponding to an integrated luminosity of 2.2 fb{sup -1} collected by the CDF II detector at Fermilab, and looks for a resonance in the invariant mass distribution of two jets in the lepton+jets sample of t{bar t} candidates. We observe no evidence of charged Higgs bosons in top quark decays. Hence, 95% upper limits on the top quark decay branching ratio are placed at {Beta}(t {yields} H{sup +}b) < 0.1 to 0.3 for charged Higgs boson masses of 60 to 150 GeV/c{sup 2}, assuming {Beta}(H{sup +} {yields} c{bar s}) = 1.0. The upper limits on {Beta}(t {yields} H{sup +}b) can also be used as model-independent limits on the decay branching ratio of top quarks to generic scalar charged bosons beyond the standard model.

Abstract: summary. The objective of this study was to evaluate the risk of transfusion-associated septic events in Taiwan. In Taiwan, most blood components are provided from blood centres; so platelet (PLT) bacterial contaminations are rarely reported. The study's aim is to investigate the prevalence of PLT bacterial contamination in Kaoshiung Armed Forces General Hospital by using BacT/ALERT system for routine screening. A total of 82 apheresis and 2256 whole blood-derived PLT units were tested. A measured quantity of 1 mL aliquots were taken as samplings from all blood bag tubing of PLT units, and then further incubated in a bacterial detection system (BacT/ALERT). The subcultures of true-positive bottles underwent bacterial identification by using Vitek system, microscopic observation and culture-based methods. Eight units (0·34%, 8 of 2338) were found to have bacterial contamination. The true-positive rate of the whole blood-derived and apheresis PLTs was 0·31% (7 of 2256) and 1·22% (1 of 82), respectively. Six microorganisms were identified with the most dominate being Staphylococcus epidermidis. One case of transfusion-associated sepsis was confirmed; in addition, the holding period of PLTs (F = 4·522, P = 0·034) and positive detection of PLT bacterial contamination (F = 46·605,P < 0·001) were associated with post-transfusion sepsis. Thus, in this study, although the transfusion-associated septic event was rarely found and PLT units were provided from blood centres, bacterial screening was necessary to safely quarantine the transfusion. The holding period of PLT units should be no more than 4 days in order to avoid possible bacterial contamination.

Abstract: A dual-wavelength fiber-optic pulse oximetry system was developed for the purposes of estimating oxygen saturation from the esophagus. A probe containing miniature right-angled glass prisms was used to record photoplethysmographic (PPG) signals from the esophageal wall. Signals were recorded successfully in 19 of 20 patients, demonstrating that PPG signals could be reliably obtained from an internal vascularized tissue site such as the esophageal epithelium. The value of the mean oxygen saturation recorded from the esophagus was 94.0 +/- 4.0%. These results demonstrate that SpO(2) may be estimated in the esophagus using a fiber-optic probe and this may be the first report of such measurements.

Abstract: In CDF we have observed the reactions p + (p) over bar -> p + X + (p) over bar, with X being a centrally produced J/psi, psi(2S), or chi(c0), and gamma gamma -> mu(+)mu(-) in p (p) over bar collisions at root s = 1.96 TeV. The event signature requires two oppositely charged central muons, and either no other particles or one additional photon detected. Exclusive vector meson production is as expected for elastic photoproduction, gamma + p -> J/psi(psi(2S)) + p, observed here for the first time in hadron-hadron collisions. We also observe exclusive chi(c0) -> J/psi + gamma. The cross sections d sigma/dy vertical bar(y=0) for J/psi, psi(2S), and chi(c0) are 3.92 +/- 0: 25(stat) +/- 0.52(syst) nb, 0.53 +/- 0.09(stat) +/- 0.10(syst) nb, and 76 +/- 10(stat) +/- 10(syst) nb, respectively, and the continuum is consistent with QED. We put an upper limit on the cross section for Odderon exchange in exclusive J/psi production.

Abstract: This paper reports a measurement of the cross section for the pair production of top quarks in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ at the Fermilab Tevatron. The data were collected from the CDF run II detector in a set of runs with a total integrated luminosity of $1.1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. The cross section is measured in the dilepton channel, the subset of $t\overline{t}$ events in which both top quarks decay through $t\ensuremath{\rightarrow}Wb\ensuremath{\rightarrow}\ensuremath{\ell}\ensuremath{\nu}b$, where $\ensuremath{\ell}=e$, $\ensuremath{\mu}$, or $\ensuremath{\tau}$. The lepton pair is reconstructed as one identified electron or muon and one isolated track. The use of an isolated track to identify the second lepton increases the $t\overline{t}$ acceptance, particularly for the case in which one $W$ decays as $W\ensuremath{\rightarrow}\ensuremath{\tau}\ensuremath{\nu}$. The purity of the sample may be further improved at the cost of a reduction in the number of signal events, by requiring an identified $b$ jet. We present the results of measurements performed with and without the request of an identified $b$ jet. The former is the first published CDF result for which a $b$-jet requirement is added to the dilepton selection. In the CDF data there are 129 pretag $\mathrm{\text{lepton}}+\mathrm{\text{track}}$ candidate events, of which 69 are tagged. With the tagging information, the sample is divided into tagged and untagged subsamples, and a combined cross section is calculated by maximizing a likelihood. The result is ${\ensuremath{\sigma}}_{t\overline{t}}=9.6\ifmmode\pm\else\textpm\fi{}1.2(\mathrm{stat}{)}_{\ensuremath{-}0.5}^{+0.6}(\mathrm{sys})\ifmmode\pm\else\textpm\fi{}0.6(\mathrm{lum})\text{ }\text{ }\mathrm{pb}$, assuming a branching ratio of $\mathrm{BR}(W\ensuremath{\rightarrow}\ensuremath{\ell}\ensuremath{\nu})=10.8%$ and a top mass of ${m}_{t}=175\text{ }\text{ }\mathrm{GeV}/{c}^{2}$.

Abstract: We present a measurement of the transverse momentum with respect to the jet axis (${k}_{t}$) of particles in jets produced in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$. Results are obtained for charged particles in a cone of 0.5 radians around the jet axis in events with dijet invariant masses between 66 and $737\text{ }\text{ }\mathrm{GeV}/{c}^{2}$. The experimental data are compared to theoretical predictions obtained for fragmentation partons within the framework of resummed perturbative QCD using the modified leading log and next-to-modified leading log approximations. The comparison shows that trends in data are successfully described by the theoretical predictions, indicating that the perturbative QCD stage of jet fragmentation is dominant in shaping basic jet characteristics.

Abstract: We present a measurement of the $\ttbar$ differential cross section with respect to the $\ttbar$ invariant mass, dSigma/dMttbar, in $\ppbar$ collisions at $\sqrt{s}=1.96$ TeV using an integrated luminosity of $2.7\invfb$ collected by the CDF II experiment. The $\ttbar$ invariant mass spectrum is sensitive to a variety of exotic particles decaying into $\ttbar$ pairs. The result is consistent with the standard model expectation, as modeled by \texttt{PYTHIA} with \texttt{CTEQ5L} parton distribution functions.

Abstract: A search for new physics using three-lepton (trilepton) data collected with the CDF II detector and corresponding to an integrated luminosity of 976 pb(-1) is presented. The standard model predicts a low rate of trilepton events, which makes some supersymmetric processes, such as chargino-neutralino production, measurable in this channel. The mu mu + l signature is investigated, where l is an electron or a muon, with the additional requirement of large missing transverse energy. In this analysis, the lepton transverse momenta with respect to the beam direction (p(T)) are as low as 5 GeV/c, a selection that improves the sensitivity to particles that are light as well as to ones that result in leptonically decaying tau leptons. At the same time, this low-p(T) selection presents additional challenges due to the non-negligible heavy-quark background at low lepton momenta. This background is measured with an innovative technique using experimental data. Several dimuon and trilepton control regions are investigated, and good agreement between experimental results and standard-model predictions is observed. In the signal region, we observe one three-muon event and expect 0.4 +/- 0.1 mu mu + l events from standard-model processes.

Abstract: This article presents the first measurement of the ratio of branching fractions B(Lambda(0)(b) -> Lambda(+)(c) mu(-) (nu) over bar (mu))/B(Lambda(0)(b) -> Lambda(+)(c) pi(-)). Measurements in two control samples using the same technique B((B) over bar (0) -> D+ mu(-) (nu) over bar (mu))/B((B) over bar (0) -> D+ pi(-)) and B((B) over bar (0) -> D*(2010)(+) mu(-) (nu) over bar (mu))/B((B) over bar (0) -> D*(2010)(+) pi(-)) are also reported. The analysis uses data from an integrated luminosity of approximately 172 pb(-1) of p (p) over bar collisions at root s = 1: 96 TeV, collected with the CDF II detector at the Fermilab Tevatron. The relative branching fractions are measured to be B(Lambda(0)(b) -> Lambda(+)(c) mu(-) (nu) over bar (mu))/B(Lambda(0)(b) -> Lambda(+)(c) pi(-)) = 16.6 +/- 3.0(stat) +/- 1.0(syst) (+2.6)(-3.4) (PDG) +/- 0.3(EBR), B((B) over bar (0) -> D+ mu(-) (nu) over bar (mu))/B((B) over bar (0) -> D+ pi(-)) = 9.9 +/- 1.0(stat) +/- 0.6(syst) +/- 0.4(PDG) +/- 0.5(EBR), and B((B) over bar (0)-> D*(2010)(+) mu(-) (nu) over bar (mu))/B((B) over bar (0) -> D*(2010)(+) pi(-)) = 16.5 +/- 2.3(stat) +/- 0.6(syst) +/- 0.5(PDG) +/- 0.8(EBR). The uncertainties are from statistics (stat), internal systematics (syst), world averages of measurements published by the Particle Data Group or subsidiary measurements in this analysis (PDG), and unmeasured branching fractions estimated from theory (EBR), respectively. This article also presents measurements of the branching fractions of four new Lambda(0)(b) semileptonic decays: Lambda(0)(b) -> Lambda(c)(2595)(+) mu(-) (nu) over bar (mu), Lambda(0)(b) -> Lambda(c)(2625)(+) mu(-) (nu) over bar (mu), Lambda(0)(b) -> Sigma(c)(2425)(0) pi(+) mu(-) (nu) over bar (mu) , and Lambda(0)(b) -> Sigma(c)(2455)(++) pi(-) mu(-) (nu) over bar (mu), relative to the branching fraction of the Lambda(0)(b) -> Lambda(+)(c) mu(-) (nu) over bar (mu) decay. Finally, the transverse-momentum distribution of Lambda(0)(b) baryons produced in p (p) over bar collisions is measured and found to be significantly different from that of (B) over bar (0) mesons, which results in a modification in the production crosssection ratio sigma(Lambda b0)/sigma((B) over bar0) with respect to the CDF I measurement.

Abstract: Models of maximal flavor violation (MxFV) in elementary particle physics may contain at least one new scalar SU(2) doublet field {phi}{sub FV}=({eta}{sup 0},{eta}{sup +}) that couples the first and third generation quarks (q{sub 1}, q{sub 3}) via a Lagrangian term L{sub FV}={xi}{sub 13}{phi}{sub FV}q{sub 1}q{sub 3}. These models have a distinctive signature of same-charge top-quark pairs and evade flavor-changing limits from meson mixing measurements. Data corresponding to 2 fb{sup -1} collected by the Collider Dectector at Fermilab II detector in pp collisions at {radical}(s)=1.96 TeV are analyzed for evidence of the MxFV signature. For a neutral scalar {eta}{sup 0} with m{sub {eta}{sup 0}}=200 GeV/c{sup 2} and coupling {xi}{sub 13}=1, {approx}11 signal events are expected over a background of 2.1{+-}1.8 events. Three events are observed in the data, consistent with background expectations, and limits are set on the coupling {xi}{sub 13} for m{sub {eta}{sup 0}}=180-300 GeV/c{sup 2}.

Abstract: We search for b{yields}s{mu}{sup +}{mu}{sup -} transitions in B meson (B{sup +}, B{sup 0}, or B{sub s}{sup 0}) decays with 924 pb{sup -1} of pp collisions at {radical}(s)=1.96 TeV collected with the CDF II detector at the Fermilab Tevatron. We find excesses with significances of 4.5, 2.9, and 2.4 standard deviations in the B{sup +}{yields}{mu}{sup +}{mu}{sup -}K{sup +}, B{sup 0}{yields}{mu}{sup +}{mu}{sup -}K*(892){sup 0}, and B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -}{phi} decay modes, respectively. Using B{yields}J/{psi}h (h=K{sup +}, K*(892){sup 0}, {phi}) decays as normalization channels, we report branching fractions for the previously observed B{sup +} and B{sup 0} decays, B(B{sup +}{yields}{mu}{sup +}{mu}{sup -}K{sup +})=(0.59{+-}0.15{+-}0.04)x10{sup -6}, and B(B{sup 0}{yields}{mu}{sup +}{mu}{sup -}K*(892){sup 0})=(0.81{+-}0.30{+-}0.10)x10{sup -6}, where the first uncertainty is statistical, and the second is systematic. We set an upper limit on the relative branching fraction B(B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -}{phi})/B(B{sub s}{sup 0}{yields}J/{psi}{phi})

Abstract: This pilot investigation was undertaken to assess the performance of a novel fiber-optic cerebral pulse oximetry system. A fiber-optic probe designed to pass through the lumen of a cranial bolt of the type used to make intracranial pressure measurements was used to obtain optical reflectance signals directly from the brain tissue. Preliminary results from seven patients measured in the operating theatre and ITU are presented. Estimations of cerebral arterial oxygen saturation derived from a frequency domain-based algorithm are compared with pulse oximetry (SpO2) and hemoximeter (SaO2) blood samples. The mean (plusmnSD) difference between cerebral oxygen saturation (ScaO2) and finger SpO2 (in saturation units) was -7.47(plusmn3 .4)%. The mean (plusmnSD) difference between ScaO2 and blood SaO2 was -7.37(plusmn2.8)%.

243. Mechanical and Electromyographic Response to Stimulated Contractions in Paralyzed Tibialis Anterior Post Fatiguing Stimulations

Abstract: Muscle fatigue is one of the most important problems resulting when functional electrical stimulation is implemented. After muscle fatigue, the manifestation of post fatigue recovery process is hence necessary for the external control of electrically elicited muscle contractions. Thirteen able-bodied young adults were recruited for this study. For inducing muscle fatigue, a modified Burke fatigue protocol was delivered to activate the tibialis anterior for 4 minutes. Before and after the modified Burke fatigue protocol, a series of pulse train with three pulses of 1 Hz and 7 pulses of 20 Hz of stimulation frequency, were delivered to induce 3 twitches and a fused contraction at 1, 3 and then followed every 5 minutes for 60 minutes. When the muscle was stimulated, the stimulus-response EMG and the generated ankle dorsiflexion torque were collected for further analyses. This study found the recovery process of muscle fatigue could be modeled by a first order exponential equation. The properties in twitched and tetanic contraction were found to be different. The recovery process was found faster in tetanic muscle contraction. The disassociation between mechanical and myoelectric activities was found in the recovery process, especially in the twitch contraction. These findings will help researchers and clinicians predict the muscle force and permit a better adjustment of the stimulation parameters.

Abstract: A dual-wavelength fibre-optic pulse oximetry system is described for the purposes of estimating oxygen saturation (SpO2) from the oesophagus. A probe containing miniature right-angled glass prisms was used to record photoplethysmographic (PPG) signals from the oesophageal wall. Signals were recorded successfully in 19 of 20 patients, demonstrating that PPG signals could be reliably obtained from an internal vascularised tissue site such as the oesophageal epithelium. The value of the mean oxygen saturation recorded from the oesophagus was 94.0 ± 4.0%. These results demonstrate that SpO2 may be estimated in the oesophagus using a fibre-optic probe.

246. Competitive adsorption of water-soluble polymers on attapulgite clay

Abstract: The individual, competitive, and displacement adsorption of polyvinyl alcohol (PVOH), hydroxyethyl cellulose (HEC), and hydroxypropylmethyl cellulose (HPMC) in aqueous solution onto an attapulgite clay has been systematically studied. For the individual adsorption experiments, the amount of polymer adsorbed at equilibrium decreased in the order PVOH, HEC, HPMC. In the competitive adsorption experiments, the adsorption level of each polymer is diminished by the presence of a competing polymeric species. Binary mixtures of a cellulosic polymer (HEC or HPMC) with PVOH result in a substantial reduction in the amount of cellulosic polymer adsorbed. In the displacement adsorption studies, the sequential addition of HEC or HPMC is not able to displace previously adsorbed PVOH molecules to any appreciable extent. However, the addition of PVOH to previously equilibrated HEC/clay or HPMC/clay suspensions results in a large amount of the adsorbed cellulosic polymer being displaced by PVOH, especially under conditions of high surface coverage. These results indicate that PVOH is preferentially adsorbed on the clay surface and the strength of attachment to the surface is greater for PVOH than for either cellulosic polymer.

Abstract: We present a search for associated production of the standard model (SM) Higgs boson and a Z boson where the Z boson decays to two leptons and the Higgs decays to a pair of b quarks in p{bar p} collisions at the Fermilab Tevatron. We use event probabilities based on SM matrix elements to construct a likelihood function of the Higgs content of the data sample. In a CDF data sample corresponding to an integrated luminosity of 2.7 fb{sup -1} we see no evidence of a Higgs boson with a mass between 100 GeV/c{sup 2} and 150 GeV/c{sup 2}. We set 95% confidence level (C.L.) upper limits on the cross-section for ZH production as a function of the Higgs boson mass m{sub H}; the limit is 8.2 times the SM prediction at m{sub H} = 115 GeV/c{sup 2}.

Abstract: We present measurements of the forward-backward charge asymmetry in top pair production using 1.9 fb;{-1} of pp[over ] collisions at sqrt[s]=1.96 TeV recorded with the Collider Detector at Fermilab II. Correcting for acceptance and measurement dilutions we obtain parton-level asymmetries of A_{FB};{pp[over ]}=0.17+/-0.08 in the pp[over ] frame and A_{FB};{tt[over ]}=0.24+/-0.14 in the tt[over ] frame. The values are consistent with the standard model expectation and disfavor exotic production mechanisms with significant negative values.

Abstract: We report a search for the flavor-changing neutral-current decay of the top quark t-->Zq (q=u, c) in pp collisions at sqrt[s]=1.96 TeV using a data sample corresponding to an integrated luminosity of 1.9 fb(-1) collected by the CDF II detector. This decay is strongly suppressed in the standard model and an observation of a signal at the Fermilab Tevatron would be an indication of physics beyond the standard model. Using Z+ > or = 4 jet final state candidate events, with and without an identified bottom quark jet, we obtain an upper limit of B(t-->Zq) < 3.7% at 95% C.L.

Abstract: We present the results of searches for large extra dimensions in samples of events with large missing transverse energy E_{T} and either a photon or a jet produced in pp[over ] collisions at sqrt[s]=1.96 TeV collected with the Collider Detector at Fermilab II. For gamma+E_{T} and jet+E_{T} candidate samples corresponding to 2.0 and 1.1 fb;{-1} of integrated luminosity, respectively, we observe good agreement with standard model expectations and obtain a combined lower limit on the fundamental parameter of the large extra dimensions model M_{D} as a function of the number of extra dimensions in the model.
