Abstract

The energy dependence of the neutrino-iron and antineutrino-iron inclusive charged-current cross sections and their ratio have been measured using a high-statistics sample with the MINOS near detector exposed to the NuMI beam from the main injector at Fermilab. Neutrino and antineutrino fluxes were determined using a low hadronic energy subsample of charged-current events. We report measurements of ν−Fe (ν⎯⎯−Fe) cross section in the energy range 3–50 GeV (5–50 GeV) with precision of 2%–8% (3%–9%) and their ratio which is measured with precision 2%–8%. The data set spans the region from low energy, where accurate measurements are sparse, up to the high-energy scaling region where the cross section is well understood., Physics

Abstract

This paper reports results from a search for νμ→νe transitions by the MINOS experiment based on a 7×1020 protons-on-target exposure. Our observation of 54 candidate νe events in the far detector with a background of 49.1±7.0(stat)±2.7(syst) events predicted by the measurements in the near detector requires 2sin 2(2θ13)sin 2θ23<0.12(0.20) at the 90% C.L. for the normal (inverted) mass hierarchy at δCP=0. The experiment sets the tightest limits to date on the value of θ13 for nearly all values of δCP for the normal neutrino mass hierarchy and maximal sin 2(2θ23)., Physics

Abstract

A search for depletion of the combined flux of active neutrino species over a 735 km baseline is reported using neutral-current interaction data recorded by the MINOS detectors in the NuMI neutrino beam. Such a depletion is not expected according to conventional interpretations of neutrino oscillation data involving the three known neutrino flavors. A depletion would be a signature of oscillations or decay to postulated non-interacting "sterile" neutrinos, scenarios not ruled out by existing data. From an exposure of 3.18x10^{20} protons on target in which neutrinos of energies between ~500 MeV and 120 GeV are produced predominantly as nu_mu, the visible energy spectrum of candidate neutral-current reactions in the MINOS far detector is reconstructed. Comparison of this spectrum to that inferred from a similarly selected near detector sample shows that of the portion of the nu_mu flux observed to disappear in charged-current interaction data, the fraction that could be converting to a sterile state is less than 52% at 90% confidence level (C.L.). The hypothesis that active neutrinos mix with a single sterile neutrino via oscillations is tested by fitting the data to various models. In the particular four-neutrino models considered, the mixing angles theta_{24} and theta_{34} are constrained to be less than 11 degrees and 56 degrees at 90% C.L., respectively. The possibility that active neutrinos may decay to sterile neutrinos is also investigated. Pure neutrino decay without oscillations is ruled out at 5.4 standard deviations. For the scenario in which active neutrinos decay into sterile states concurrently with neutrino oscillations, a lower limit is established for the neutrino decay lifetime tau_3/m_3 > 2.1x10^{-12} s/eV at 90% C.L.., Physics

Abstract

We searched for a sidereal modulation in the MINOS far detector neutrino rate. Such a signal would be a consequence of Lorentz and CPT violation as described by the standard-model extension framework. It also would be the first detection of a perturbative effect to conventional neutrino mass oscillations. We found no evidence for this sidereal signature, and the upper limits placed on the magnitudes of the Lorentz and CPT violating coefficients describing the theory are an improvement by factors of 20–510 over the current best limits found by using the MINOS near detector., Physics

Abstract

(G. J. Feldman is the Harvard author) The Main Injector Neutrino Oscillation Search (MINOS) experiment uses an accelerator-produced neutrino beam to perform precision measurements of the neutrino oscillation parameters in the "atmospheric neutrino" sector associated with muon neutrino disappearance. This long-baseline experiment measures neutrino interactions in Fermilab's NuMI neutrino beam with a near detector at Fermilab and again 735 km downstream with a far detector in the Soudan Underground Laboratory in northern Minnesota. The two detectors are magnetized steel-scintillator tracking calorimeters. They are designed to be as similar as possible in order to ensure that differences in detector response have minimal impact on the comparisons of event rates, energy spectra and topologies that are essential to MINOS measurements of oscillation parameters. The design, construction, calibration and performance of the far and near detectors are described in this paper., Physics

Abstract

(G. J. Feldman is the Harvard author) This Letter reports new results from the MINOS experiment based on a two-year exposure to muon neutrinos from the Fermilab NuMI beam. Our data are consistent with quantum-mechanical oscillations of neutrino flavor with mass splitting |delta m^2|=(2.43±0.13)×10^-3 eV^2 (68% C.L.) and mixing angle (sin(2*theta))^2>0.90 (90% C.L.). Our data disfavor two alternative explanations for the disappearance of neutrinos in flight: namely, neutrino decays into lighter particles and quantum decoherence of neutrinos, at the 3.7 and 5.7 standard-deviation levels, respectively., Physics

Abstract

A search for a sidereal modulation in the MINOS near detector neutrino data was performed. If present, this signature could be a consequence of Lorentz and CPT violation as predicted by a class of extensions to the Standard Model. No evidence for a sidereal signal in the data set was found, implying that there is no significant change in neutrino propagation that depends on the direction of the neutrino beam in a sun-centered inertial frame. Upper limits on the magnitudes of the Lorentz and CPT violating terms in these extensions to the Standard Model lie between 0.01-1% of the maximum expected, assuming a suppression of these signatures by factor of 10^-17., Physics

219. GUS transformation of the maize fungal endophyte <e1>Fusarium moniliforme</e1>

Abstract

Visual markers detectable by histochemical staining have been developed for analysing the time course and tissue specificity of maize infections by Fusarium moniliforme. Three F. moniliforme strains, RRC 374, MRC 826 and RRC PAT, were transformed with a plasmid, pHPG, containing the gusA reporter gene which codes for β-glucuronidase (GUS) and the hph gene for hygromycin resistance as the selectable marker. Introduction of plasmid DNA into germinating conidia yielded 1·2×10−7 transformants per conidium; expression of both gusA and hph was however, transient. Stable transformants were obtained using protoplasts as the recipient, but transformation frequency was reduced. Southern blot and PCR analyses confirmed incorporation of pHPG into the genome of all three F. moniliforme strains with gusA properly inserted in MRC 826 and RRC PAT, but apparently disrupted in RRC 374. The growth pattern for transformed F. moniliforme isolates and the parental wild types followed a sigmoid curve on minimal and enriched media. Hygromycin totally inhibited growth for wild type isolates, but not of transformants. Transformed isolates maintained the ability to infect the maize plant. Thus, this study is the first report of F. moniliforme transformed with a visibly detectable reporter gene to use for analysing this endophyte-host interaction of world-wide importance to animal and human health.

220. Circulating Histamine and Neutrophil Chemotactic Activity During Allergen-Induced Asthma: The Effect of Inhaled Antihistamines and Anti-Allergic Compounds

Author

Morgan, D. J. R., Moodley, I., Cundell, D. R., Sheinman, B. D., Smart, W., and Davies, R. J.

Abstract

1. Plasma histamine and serum neutrophil chemotactic activity (S-NCA) were measured in ten atopic asthmatic patients on four separate occasions after allergen bronchial provocation testing (BPT). 2. Single doses of inhaled sodium cromoglycate (SCG; 20 mg), clemastine (0.5 mg), ketotifen (0.5 mg) and isotonic saline (0.9% NaCl) placebo were administered 30 min before bronchial provocation testing in random order and double-blind. 3. The airflow obstruction after BPT was monitored by measurement of forced expiratory volume in 1s (FEV1). Plasma histamine was measured by the double-isotope radioenzymatic assay and S-NCA by a modified Boyden chamber technique. 4. A highly significant decrease in FEV1 after BPT occurred on the placebo pre-treatment visit (P < 0.001). Prior administration of inhaled SCG, clemastine and ketotifen significantly reduced the decrease in airflow obstruction seen after BPT when compared with placebo treatment (P < 0.01, P < 0.02, P < 0.05 respectively). 5. No significant alteration in plasma histamine was detected during allergen-induced airflow obstruction. 6. Levels of S-NCA were significantly higher 5, 10 and 15 min after BPT when compared with the pre-challenge level (P < 0.01, P < 0.01, P < 0.001 respectively). These levels were not significantly decreased when airflow obstruction was inhibited by the prior inhalation of SCG, clemastine or ketotifen.

221. Monoclonal antibodies against colonization factor antigen I pili from enterotoxigenic Escherichia coli

Author

Worobec, E A, Shastry, P, Smart, W, Bradley, R, Singh, B, and Paranchych, W

Abstract

Hybridomas secreting monoclonal antibodies directed against intact colonization factor antigen I pili have been produced by the fusion of spleen cells from immunized BALB/c mice with NS1/SP2 myeloma cells. The four monoclones with the highest antibody titer, as detected by enzyme-linked immunosorbant assay (ELISA), were chosen for antibody amplification by production of mouse ascitic fluid. These four were examined for antibody specificity by ELISA and immunoblot assays, using six different pilus types. Three of the four monoclonal isolates were specific for only colonization factor antigen I pili in both assays, whereas the remaining isolate showed a distinct cross-reactivity with K99 pili in the ELISA assay but not in immunoblot analysis. These results indicate that this monoclone may be recognizing a common structural element between the two adhesive pilus types.

222. Mapping of the T-cell recognition sites of Pseudomonas aeruginosa PAK polar pili

Author

Smart, W, Sastry, P A, Paranchych, W, and Singh, B

Abstract

The polar pili of Pseudomonas aeruginosa consist of a subunit protein, pilin, which is a 144-residue polypeptide that contains a hydrophobic N-terminal region and eight hydrophilic regions distributed throughout the remainder of the molecule. T cells from mice immunized with pili or whole bacteria gave good pilus-specific T-cell proliferation responses. To delineate the T-cell antigenic regions of the pilin, T-cell blasts were generated from lymph nodes of pilus-primed BALB/c mice. These blasts were tested in vitro in T-cell proliferation assays for reactivity against the fragments of the pilin subunit prepared by enzymatic digestion. Citraconylation followed by trypsin digestion (cT) of the pilin subunit cleaved the protein into four fragments, cTI (residues 1 to 30), cTII (residues 31 to 53), cTIII (residues 54 to 120), and cTIV (residues 121 to 144). The ability to stimulate the T cells was found to reside in the cTI and cTIII regions, but not in the cTII or cTIV regions. A subfragment of cTIII, containing residues 82 to 104, was identified as the major T-cell recognition site within the cTIII region of the pilin molecule. A cross-reactivity was observed between pili from two strains of P. aeruginosa, namely, PAK and PAO, at the T-cell level. This cross-reactivity probably resulted from the sequence homology in the hydrophobic N-terminal region of these two molecules.

223. Combinatorial regulation of the Saccharomyces cerevisiae CAR1 (arginase) promoter in response to multiple environmental signals

Author

Smart, W C, Coffman, J A, and Cooper, T G

Abstract

CAR1 (arginase) gene expression responds to multiple environmental signals; expression is induced in response to the intracellular accumulation of arginine and repressed when readily transported and catabolized nitrogen sources are available in the environment. Up to 14 cis-acting sites and 9 trans-acting factors have been implicated in regulated CAR1 transcription. In all but one case, the sites are redundant. To test whether these sites actually participate in CAR1 expression, each class of sites was inactivated by substitution mutations that retained the native spacing of the CAR1 cis-acting elements. Three types of sites function independently of the nitrogen source: two clusters of Abflp- and Rap1p-binding sites, and a GC-rich sequence. Two different sets of nitrogen source-dependent sites are also required: the first consists of two GATAA-containing UASNTR sites that mediate nitrogen catabolite repression-sensitive transcription, and the second is arginine dependent and consists of three UAS1 elements that activate transcription only when arginine is present. A single URS1 site mediates repression of CAR1 arginine-independent upstream activator site (UAS) activity in the absence of arginine and the presence of a poor nitrogen source (a condition under which the inducer-independent Gln3p can function in association with the UASNTR sites). When arginine is present, the combined activity of the UAS elements overcomes the negative effects mediated by URS1. Mutation of the classes of sites either singly or in combination markedly alters CAR1 promoter operation and control, supporting the idea that they function synergistically to regulate expression of the gene.

224. Influence of Changing the Kind of Fat in the Diet at Various Weight Intervals on Carcass Fat Characteristics of Swine

Author

Blumer, T. N., Barrick, E. R., Brown, W. L., Smith, F. H., and Smart, W. W. G.

Abstract

Twenty hogs were divided into five groups of equal numbers of which four groups were fed a soft fat producing basal diet containing 10% soybean oil. Three groups were fed to varying specified weights at which time coconut oil, a hardening oil, replaced the soybean oil until the hogs reached slaughter weight. The fourth group received soybean oil from weaning weight to market weight, while the fifth group received coconut oil for the same period. When the hogs were fed coconut oil from weights of 150 to 205 lb. during the last 30 days of the fattening period, carcasses were satisfactory in firmness.Determinations made on the fat showed decreases in iodine number as the length of feeding period on coconut oil increased. Decreases were similarly found for linoleic, linolenic and arachidonic acids. Fat stability tests conducted by determining periodically the peroxide values on stored cured bacons of each carcass supported the fatty acid composition values and manual firmness scores.

225. Inhibition of Rumen Cellulose Digestion by Extracts of Sericea Lespedeza

Author

Lyford, S. J., Smart, W. W. G., and Bell, T. A.

Abstract

Cellulose hydrolysis was found to be inhibited by a purified preparation of a waterextractable inhibitor from fresh sericea forage. This inhibition was obtained under rumen conditions as well as in in vitrotrials. When casein was added to the cellulose-rumen fluid mixture containing PSI, considerable protection of activity was afforded to the cellulose degrading system; but at high levels of inhibitor, casein had no effect. While fine chopping of the fresh material or drying of the forage reduced the amount of extractable inhibitor to a low level, the digestibility of the cellulose of the dry form was not higher than the fresh forage.

226. Evaluation of Hemoglobin, Myoglobin, Blood Oxygen Content and Organoleptic Qualities of Beef from Steers Fed Grain on Pasture or Cut Forage and Grain in Drylot

Author

Craig, H. B., Blumer, T. N., Smart, W. W. G., and Wise, M. B.

Abstract

Thirty-four beef steers (17 per treatment) received a ration of grain on pasture or cut forage and grain in drylot to ascertain the effect of these treatments on certain characteristics influencing muscle color. There was a significant difference between treatments with regard to blood hemoglobin content 72 days after beginning the experiment. Differences after 0, 97 and 145 days were not significant. Myoglobin content of the l. dorsimuscle and of the muscles of the foreshank was similar between treatments. Cattle fattened on pasture had values for visual color, pH, moisture content and ether extract which were similar to those of their counterparts fed grain andchopped grass in drylot. Venous blood oxygen levels were significantly higher in the steers on pasture both at 97 and 145 days.Organoleptic evaluation did not reveal appreciable treatment differences among the various palatability factors considered. Several significant correlations (disregarding treatment) were noted. There was a tendency for darker colored steaks to be less tender. Fatness was significantly related to juiciness, softness, flavor and shear value.The premise that pasture-fed animals have darker colored muscles because of increased exercise is not substantiated by the results of this study.

227. Nature and Variability of Marbling Deposits in Longissimus DorsiMuscle of Beef Carcasses

Author

Blumer, T. N., Craig, H. B., Pierce, E. A., Smart, W. W. G., and Wise, M. B.

Abstract

This study was undertaken to determine the amount of variation of intramuscular fat (marbling) within a section of the longissimus dorsi(rib-eye) muscle of beef carcasses.The rib-eye muscle comprising the 9th, 10th and 11th rib section was frozen and then cut into ¼-in. cross-sectional slices. Each slice was thawed and then graded for marbling according to U.S.D.A. Grading Standards with the exception that each grade was further divided into upper, middle and lower one-thirds. A range in marbling grades by as much as 2/3 was found among the slices within one rib-eye muscle section. Standard deviations of marbling scores among the muscles ranged from 0.65 to 2.75.Photographs illustrating some of the marbling patterns are included. The marbling pattern appeared to be somewhat consistent in that heavy marbling deposits occurred at more or less regular intervals within the rib-eye muscles.

228. Influence of Energy-Protein Ratio on Performance and Carcass Characteristics of Swine

Author

Clawson, A. J., Blumer, T. N., Smart, W. W. G., and Barrick, E. R.

Abstract

Seventy-two pigs were used to determine the influence of calorie-protein ratio and fat level in the ration on performance and carcass characteristics. The rations, containing graded levels of from 10 to 18% protein, were formulated so that a similar ratio of amino acids was maintained in all diets. Daily feed consumption was influenced by both calorie-protein ratio and by fat level in the ration. However, gross energy intake was not significantly influenced by either ration treatment. Growth rate, during the first 28 days on test, was significantly influenced by energy-protein ratio. The narrow ratio supported the most rapid rate of gain. This difference was not apparent at the time the pigs reached market weight. Added fat resulted in a significant improvement in both rate of gain and in feed per pound of gain. Energy utilization, however, was not influenced by either calorie-protein ratio or by fat level in the ration. Physical measurements and chemical determination made on the carcasses were not significantly influenced by ration treatments. Factors influencing feed consumption of pigs are discussed.

229. Chemical, Physical and Organoleptic Evaluation of Aged Country-Style Hams from Hogs Fed Rations with and without Peanut Oil

Author

Craig, H. B., Blumer, T. N., Clawson, A. J., and Smart, W. W. G.

Abstract

Aged country-style hams from hogs fed a ration containing 10% peanut oil had higher iodine numbers, 3.32% lower free fatty acid values, 1.96% more chemical fat, more oleic, linoleic and linolenic acids and received higher taste panel scores for aged flavor than hams from hogs receiving no peanut oil. During aging the relative percent of myristic, palmitic, stearic and oleic acids decreased; whereas, palmitoleic, linoleic and linolenic acids increased approximately two-fold, for both groups of hams. Hams from hogs on added peanut oil lost significantly less weight during aging than did the hams from hogs receiving no peanut oil.Left hams averaged 1.75% more chemical fat than their pair mates. Shear values were not appreciably different between lots, but were considerably lower for cooked as compared with uncooked samples.

230. Response of Pigs to Graded Levels of Soybean Meal and Added Lysine in Ten Percent Protein Rations

Author

Clawson, A. J., Barrick, E. R., and Smart, W. W. G.

Abstract

Ten percent protein rations were formulated to supply 12.5, 25, and 50% of the protein from dehulled S.B.M. The remainder of the protein was supplied by corn. These rations were fed with and without 0.4% of added lysine during two consecutive seasons. Six pigs were individually fed each ration during each season.Increasing the proportion of the protein supplied by S.B.M. resulted in significant increases in feed intake and daily gain. Carcass leanness as measured by area of longissimus dorsimuscle was significantly improved by increasing the percent of protein supplied by S.B.M. and by added lysine.

Abstract

The results of a search for W boson pair production in pp̄ collisions at √s = 1.8 TeV with subsequent decay to eμ, ee, and μμ channels are presented. Five candidate events are observed with an expected background of 3.1 ± 0.4 events for an integrated luminosity of approximately 97 pb-1. Limits on the anomalous couplings are obtained from a maximum likelihood fit of the ET spectra of the leptons in the candidate events. Assuming identical WWγ and WWZ couplings, the 95% C.L. limits are -0.62

Abstract

We report a measurement of the W boson mass based on an integrated luminosity of 82 pb-1 from pp̄ collisions at √s = 1.8 TeV recorded in 1994-1995 by the D0 detector at the Fermilab Tevatron. We identify W bosons by their decays to e v and extract the mass by fitting the transverse mass spectrum from 28 323 W boson candidates. A sample of 3563 dielectron events, mostly due to Z → ee decays, constrains models of W boson production and the detector. We measure MW = 80.44 ± 0.10(stat) ± 0.07(syst) GeV. By combining this measurement with our result form the 1992-1993 data set, we obtain Mw = 80.43 ± 0.11 GeV.

Abstract

The results of a search for W boson pair production in pp collisions at √s= 1.8 TeV with subsequent decay to eμ, ee, and μμ channels are presented. Five candidate events are observed with an expected background of 3.1 ±0.4 events for an integrated luminosity of approximately 97 pb-1. Limits on the anomalous couplings are obtained from a maximum likelihood fit of the ET spectra of the leptons in the candidate events. Assuming identical WWγ and WWZ couplings, the 95% C.L. limits are -0.62

Abstract

We have measured the ZZγ and Zγγ couplings by studying 13.1 pb-1 of pp̄ → γ + X data at √s = 1.8 TeV with the DØ detector at the Fermilab Tevatron Collider. This is the first study of hadronic Zγ production in the neutrino decay channel. Combining this measurement with our previous results using Z → ee and μμ yields the most strineent 95% C.L. limits to date on anomalous couplings: |h30Z| < 0.4, |h40Z| < 0.06 (Λ = 750 GeV).

Abstract

We present a study of Zγ+X production in pp̄ collisions at √s=1.8 TeV from 97 (87) pb-1 of data collected in the eeγ (μμγ) decay channel with the D0 detector at Fermilab. The event yield and kinematic characteristics are consistent with the standard model predictions. We obtain limits on anomalous ZZγ and Zγγ couplings for form factor scales Λ=500 GeV and Λ=750 GeV. Combining this analysis with our previous results yields 95% C.L. limits |hZ30

Abstract

Antigen-specific T cell blasts to poly-18, a polypeptide antigen of defined sequence and conformation, were generated from lymph nodes of antigen-primed BALB/cCr mice. These blasts were fused with the BW5147 thymoma to obtain anti-poly-18-reactive T cell hybridomas. All of the hybridomas were IAd-restricted and secreted IL2 in the presence of IAd/poly-18. On the basis of fine specificity analysis, these hybridomas were classified into two groups. Group A hybridomas recognized a minimal peptide sequence of Glu-Tyr-Lys-(Glu-Tyr-Ala)3-Glu-Tyr-Lys, whereas Group B needed the sequence Glu-Tyr-Ala-(Glu-Tyr-Ala)3-Glu-Tyr-Lys/Ala for activation. Three critical residues were identified in Group A hybridomas: the alanine residue at position 9, the carboxy terminal lysine, and the lysine at position 3. In Group B hybridomas, the alanine at position 3 was found to be the critical residue. We suggest that the amino acid residue at position 3 (lysine/alanine) is the T cell receptor contact residue on the poly-18 antigen in BALB/cCr mice.
