Abstract: Osteoarthritis is a degenerative disease characterized by articular cartilage degradation. Long non-coding ribonucleic acid (lncRNA) plays important roles in a series of biological processes, but its role in osteoarthritis is still not quite clear. This study aims to investigate the regulatory role of taurine upregulated gene 1 (TUG1) in osteoarthritis.The expression level of lncRNA-TUG1 in cartilages of patients with osteoarthritis and those of normal people was compared using Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Primary chondrocytes were induced by interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α), followed by expression detection of lncRNA-TUG1, microRNA-195 (miR-195), and matrix metalloproteinase-13 (MMP-13). In addition, in vitro regulatory roles of lncRNA-TUG1 and miR-195 in osteoarthritis were verified by transfection of lncRNA-TUG1 and miR-195 plasmids. The dimethylmethylene blue (DMMB) assay was performed to analyze the secretion and formation of soluble sulfated glycosaminoglycan (sGAG).The expression levels of lncRNA-TUG1 and MMP-13 in cartilages of patients with osteoarthritis were higher than those in cartilages of normal people, while the level of miR-195 decreased in cartilages of patients with osteoarthritis. After chondrocytes were induced by IL-1β and TNF-α, the expression of lncRNA-TUG1 increased. Overexpression of lncRNA-TUG1 decreased the expressions of miR-195, collagen, and aggrecan, but increased the expression of MMP-13. LncRNA-TUG1 knockdown obtained the opposite results.LncRNA-TUG1 regulates the degradation of extracellular matrix in osteoarthritis via lncRNA-TUG1/miR-195/MMP-13 axis.

Abstract: In this study, Cu/Ti diffusion couples annealed at 1023 K for 1000 h were annealed with molten Sn at 823 K for 15–480 min. With the addition of Ti, the consumption speed of Cu is greatly enhanced. At 823 K, a Cu plate with a thickness of about 3 mm dissolved from a solute into Sn in less than 15 min. Cu-Ti binary compounds still have different consumption speeds in molten Sn. The grown-out Cu-Ti binary compounds show great anisotropism in this work, and there are quick diffusion paths vertical to the Cu-Ti interface that form in them. With the progressing of annealing, different tri-junctions, which mean correlative three-phase regions in the isothermal section, appear in the samples sequentially at 823 K. After annealing at 823 K for varying times from 15 min to 480 min, the morphologies of diffusion zones are illustrated with diffusion paths.

Abstract: The aim of this meta-analysis was to systematically evaluate the diagnostic accuracy of microRNAs (miRNAs) in distinguishing malignant thyroid lesions from benign ones and to determine the potential of miRNAs as diagnostic biomarkers for thyroid cancer. The random-effect model was used to summarize the pooled estimates of diagnostic accuracy, including sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR). The summary receiver-operating characteristic curve (SROC) and area under the SROC curve (AUC) were used to further evaluate the overall diagnostic value. Overall, 20 studies from 7 articles, including 266 thyroid cancer patients and 277 controls with benign thyroid disease, were available for analysis. The pooled sensitivity, specificity, PLR, NLR, and DOR were: 0.78 (95%CI = 0.74-0.81), 0.73 (95%CI = 0.69-0.77), 3.17 (95%CI = 2.28-4.40), 0.30 (95%CI = 0.23-0.39), and 12.6 (95%CI = 8.26-19.4), respectively, and the AUC value was 0.85. The multiple miRNA assay yielded better diagnostic performance than the single miRNA assay, with sensitivity of 0.90 versus 0.75, specificity of 0.86 versus 0.71, PLR of 6.14 versus 2.71, NLR of 0.13 versus 0.36, DOR of 44.5 versus 8.81, and AUC of 0.95 versus 0.82, suggesting that the multiple miRNA assay is a more credible method for thyroid cancer detection. In summary, miRNA assays, especially multiple miRNA assays, may play an important role as a second-line diagnostic tool to improve the diagnostic accuracy of fine needle aspiration biopsy in indeterminate lesions. However, further studies are warranted to confirm our findings.

Abstract: We report results of searches for charmless hadronic B meson decays to pseudoscalar(pi^+-,K^+-,Pi^0 or Ks^0)-vector(Rho, K* or Omega) final states. Using 9.7 million BBbar pairs collected with the CLEO detector, we report first observation of B^- --> Pi^-Rho^0, B^0 --> Pi^+-Rho^-+ and B^- --> Pi^-Omega, which are expected to be dominated by hadronic b --> u transitions. The measured branching fractions are (10.4+3.3-3.4+-2.1)x10^-6, (27.6+8.4-7.4+-4.2)x10^-6 and (11.3+3.3-2.9+-1.4)x10^-6, respectively. Branching fraction upper limits are set for all the other decay modes investigated., 10 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS

Abstract: The S matrix ansatz is a rigorously model independent approach to describe the cross-sections and asymmetries in e+e- annihilation. Using the cross-sections and asymmetries measured with the L3 detector during the 1990 and 1991 running period, we determine the mass and the width of the Z boson, the contributions of the Z exchange and of the yZ interference. Including the polarization of the t lepton in the analysis, the leptonic helicity amplitudes of the scattering process are determined assuming lepton universality. The results are compared with other model independent ansatzes as realized in ZFITTER. A systematic bias of the Z mass due to the yZ interference term is detected, which leads to an underestimation of the error on mz for model independent determinations., Facultad de Ciencias Exactas

Abstract: We have measured the first and second moments of the hadronic mass-squared distribution in B -> X_c l nu, for P(lepton) > 1.5 GeV/c. We find = 0.251 +- 0.066 GeV^2, < (M_X^2 -)^2 > = 0.576 +- 0.170 GeV^4, where M_D[Bar] is the spin-averaged D meson mass. From that first moment and the first moment of the photon energy spectrum in b -> s gamma, we find the HQET parameter lambda_1 (MS[Bar], to order 1/M^3 and beta_0 alpha_s^2) to be -0.24 +- 0.11 GeV^2. Using these first moments and the B semileptonic width, and assuming parton-hadron duality, we obtain |V_cb| = 0.0404 +- 0.0013., Comment: 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS, submitted to PRL

Abstract: We present a new determination of the Ds decay constant, f_{Ds} using 5 million continuum charm events obtained with the CLEO II detector. Our value is derived from our new measured ratio of widths for Ds -> mu nu/Ds -> phi pi of 0.173+/- 0.021 +/- 0.031. Taking the branching ratio for Ds -> phi pi as (3.6 +/- 0.9)% from the PDG, we extract f_{Ds} = (280 +/- 17 +/- 25 +/- 34){MeV}. We compare this result with various model calculations., 23 page postscript file, postscript file also available through http://w4.lns.cornell.edu/public/CLNS

Abstract: Using 13.4 $fb^{-1}$ of data collected with the CLEO detector at the Cornell Electron Storage Ring, we have observed 300 events for the two-photon production of ground-state pseudo-scalar charmonium in the decay $\eta_c$ -> $K_S K^{\mp} \pi^{\pm}$. We have measured the $\eta_c$ mass to be (2980.4 +- 2.3 (stat) +- 0.6 (sys)) MeV and its full width as (27.0 +- 5.8 (stat) +- 1.4 (sys)) MeV. We have determined the two-photon partial width of the $\eta_c$ meson to be (7.6 +- 0.8 (stat) +- 0.4 (sys) +- 2.3 (br)) keV, with the last uncertainty associated with the decay branching fraction.

Abstract: Using the CLEO~II detector, we have measured the differential cross sections for exclusive two-photon production of light pseudoscalar mesons $\pi^0$, $\eta$, and $\eta^{\prime}$. From our measurements we have obtained the form factors associated with the electromagnetic transitions $\gamma^*\gamma$ $\to$ meson. We have measured these form factors in the momentum transfer ranges from 1.5 to 9, 20, and 30 GeV$^2$ for $\pi^0$, $\eta$, and $\eta^{\prime}$, respectively, and have made comparisons to various theoretical predictions., Comment: 30 page postscript file, postscript file also available through http://w4.lns.cornell.edu/public/CLNS

Abstract: A search for rare charmless decays of B0d and B0s mesons has been performed in the exclusive channels B0d(s) →ηη0, B0d(s) →ηπ0 and B0d(s) →π0π0. The data sample consisted of three million hadronic Z decays collected by the L3 experiment at LEP from 1991 through 1994. No candidate event has been observed and the following upper limits at 90% confidence level on the branching ratios have been set: Br(B0d→ηη) −4, Br(B0s →ηη) < 1.5 x 10−3, Br(B0d→ηπ0) < 2.5 x 10−4, Br(B0s→ηπ0) < 1.0 x 10−3, Br(B0d→π0π0) < 6.0 x 10−5, Br(B0s→π0π0) < 2.1 x 10−4. These are the first experimental limits on Bd0→ηη and on the Bs0 neutral charmless modes., Facultad de Ciencias Exactas

Abstract: A series of homopeptides and their conjugates were synthesized in one pot reaction in the presence of phosphorus oxychloride and the conjugate yield was structurally dependent. Menthol and benzylamine conjugated to the homopeptides quantitatively. Homopeptides when treated with diisopropyloxyphosphite (DIPPH) and NaClO yield the corresponding N-phosphoryl peptides. Electrospray ionization-mass spectrometry (ESI-MS)/MS was used to study the structure of peptide conjugates. This paper reports a simple method to synthesize the homopeptides and their conjugate derivatives and the fact that phosphoryl peptides could also be obtained by one pot reaction.

Abstract: We have previously studied mouse Cdv (carnitine deficiency-associated gene expressed in ventricle)-1 related gene Cdv-1IR and its human counterpart CDV-1R, and revealed that mouse Cdv-1R was predominantly expressed in testis by multiple tissue northern analysis. To further localize the Cdv-1R mRNA in mouse testis and epididymis tissue, in situ hybridization study was reported in this article. In the adult mice, the Cdv-1R expression was intensively found in the epithelial cells of the caput and corpus epididymis, whereas it was moderately detected in the initial segment, and weakly in the cauda epididymis. In the seminiferous tubles of the testis, no obvious hybridization signals were observed above the background level. This Cdv-1R region-specific expression pattern in the epididimis suggests Cdv-1R may play an important role in sperm maturation. Moreover, considering the Cdv-1R has a similar expression distribution in epididymis to the OCTN2, it would appear that Cdv-1R might be involved in the carnitine pathway in the epididimis.

Abstract: We have measured the charge asymmetry in like-sign dilepton yields from B(0)B*(0) meson decays using the CLEO detector at the Cornell Electron Storage Ring. We find a(0)(ll) identical with[N(l(+)l(+))-N(l(-)l(-))]/[N(l(+)l(+))+N(l(-)l(-))] = +0.013+/-0.050+/-0.005. We combine this result with a previous, independent measurement and obtain Re(epsilon(B))/(1+ the absolute value of epsilon(B)(2)) = +0.0035+/-0.0103+/-0.0015 (uncertainties are statistical and systematic, respectively) for the CP impurity parameter, epsilon(B).

Abstract: The spectrum of charmed baryons consisting of a charmed quark and two light quarks denoted by Ac and σc baryons were investigated. The sample used in the investigation corresponds to an integrated luminosity 13.7/fb from the data taken on the Y(4S) resonance and in the continuum at energies just below the Y(4S). A broad state with an invariant mass roughly above 480 MeV above that of the Ac baryon and a narrow state with an invariant mass of 596 MeV above the Ac mass were found.

Abstract: Using 13.7 $fb^{-1}$ of data recorded by the CLEO detector at CESR, we report evidence for two new charmed baryons: one decaying into $\Xi_c^{0 \prime}\pi^+$ with the subsequent decay $\Xi_c^{0 \prime} \to \Xi_c^0 \gamma$, and its isospin partner decaying into $\Xi_c^{+ \prime} \pi^-$ followed by $\Xi_c^{+\prime} \to \Xi_c^+\gamma$. We measure the following mass differences for the two states: $M(\Xi_c^0 \gamma \pi^+)-M(\Xi_c^0)$=318.2+-1.3+-2.9 MeV, and $M(\Xi_c^+ \gamma \pi^-)-M(\Xi_c^+)$=324.0+-1.3+-3.0 MeV. We interpret these new states as the $J^P = 1/2^- \Xi_{c1}$ particles, the charmed-strange analogs of the $\Lambda_{c1}^+(2593)$.

Abstract: The CLEO experiment at the CESR collider has used 13.7 fb(-1) of data to search for the production of the Omega(0)(c) (css ground state) in e(+)e(-) collisions at square root of (s) approximately 10.6 GeV. The modes used to study the Omega(0)(c) are Omega(-)pi(+), Omega(-)pi(+)pi(0), Xi-K-pi(+)pi(+), Xi0K-pi(+), and Omega(-)pi(+)pi(+)pi(-). We observe a signal of 40.4+/-9.0(stat) events at a mass of 2694.6+/-2.6(stat)+/-1.9(syst) MeV/c(2), for all modes combined.

Abstract: We have studied two-body charmless hadronic decays of B mesons into the final states straight phiK and phiK(*). Using 9.7 million BB pairs collected with the CLEO II detector, we observe the decays B- --> phiK- and B0--> phiK(*0) with the following branching fractions: B(B--->phiK-) = (5.5(+2.1)(-1.8)+/-0.6)x10(-6) and B(B0--> phiK(*0)) = (11.5(+4.5+1.8)(-3.7-1.7))x10(-6). We also see evidence for the decays B0-->phiK0 and B---> phiK(*-). However, since the statistical significance is not overwhelming for these modes, we determine upper limits of

Abstract: We analyze 9.7x10(6) B_B pairs recorded with the CLEO detector to determine the production ratio of charged to neutral B-meson pairs produced at the Upsilon(4S) resonance. We measure the rates for B0-->J/psiK((*)0) and B+-->J/psiK((*)+) decays and use the world-average B-meson lifetime ratio to extract the relative widths f(+-) / f(00) = gamma(Upsilon(4S)-->B+B-) / gamma(Upsilon(4S)-->B0 B-0)) = 1.04+/-0.07(stat)+/-0.04(syst). With the assumption that f(+-)+f(00) = 1, we obtain f(00) = 0.49+/-0.02(stat)+/-0.01(syst) and f(+-) = 0.51+/-0.02(stat)+/-0.01(syst). This production ratio and its uncertainty apply to all exclusive B-meson branching fractions measured at the Upsilon(4S) resonance.

Abstract: Using data recorded with the CLEO II and CLEO II.V detector configurations at the Cornell Electron Storage Rings, we report the first observation and mass measurement of the ${\ensuremath{\Sigma}}_{c}^{*+}$ charmed baryon, and an updated measurement of the mass of the ${\ensuremath{\Sigma}}_{c}^{+}$ baryon. We find $M({\ensuremath{\Sigma}}_{c}^{*+})\ensuremath{-}M({\ensuremath{\Lambda}}_{c}^{+})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(231.0\ifmmode\pm\else\textpm\fi{}1.1\ifmmode\pm\else\textpm\fi{}2.0)\phantom{\rule{0ex}{0ex}}\mathrm{MeV}$, and $M({\ensuremath{\Sigma}}_{c}^{+})\ensuremath{-}M({\ensuremath{\Lambda}}_{c}^{+})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(166.4\ifmmode\pm\else\textpm\fi{}0.2\ifmmode\pm\else\textpm\fi{}0.3)\phantom{\rule{0ex}{0ex}}\mathrm{MeV}$, where the errors are statistical and systematic, respectively.

Abstract: In a sample of $9.66\times 10^6 B\bar{B}$ pairs collected with the CLEO detector we make the first observation of B decays to an $\eta_c$ and a kaon. We measure branching fractions $BR(B^+\to\eta_c K^+) = (0.69 + 0.26 - 0.21 +- 0.08 +- 0.20)\times 10^{-3}$ and $BR(B^0\to\eta_c K^0) = (1.09 + 0.55 - 0.42 +- 0.12 +- 0.31)\times 10^{-3}$, where the first error is statistical, the second is systematic and the third is from the $\eta_c$ branching fraction uncertainty. From these we extract the $\eta_c$ decay constant in the factorization approximation, $f_{\eta_c} = 335 +- 75$ MeV. We also search for B decays to a $\chi_{c0}$ and a kaon. No evidence for a signal is found and we set 90% CL upper limits: $BR(B^+\to\chi_{c0} K^+) < 4.8\times 10^{-4}$ and $BR(B^0\to\chi_{c0} K^0) < 5.0\times 10^{-4}$.

Abstract: We search for CP-violating asymmetries (Acp) in the B meson decays to K+- pi-+, K+- pi0, Ks pi+-, K+- eta', and omega pi+-. Using 9.66 million Upsilon(4S) decays collected with the CLEO detector, the statistical precision on Acp is in the range of \pm 0.12 to \pm 0.25 depending on decay mode. While CP-violating asymmetries of up to \pm 0.5 are possible within the Standard Model, the measured asymmetries are consistent with zero in all five decay modes studied., 10 pages, 3 figures

Abstract: We present a search for direct CP violation in B{sup {+-}}{yields}J/{psi}K{sup {+-}} and B{sup {+-}}{yields}{psi}(2S)K{sup {+-}} decays. In a sample of 9.7x10{sup 6} BB meson pairs collected with the CLEO detector, we have fully reconstructed 534 B{sup {+-}}{yields}J/{psi} K{sup {+-}} and 120 B{sup {+-}}{yields}{psi}(2 S)K{sup {+-}} decays with very low background. We have measured the CP -violating charge asymmetry to be [+1.8{+-}4.3(stat){+-}0. 4(syst)]% for B{sup {+-}}{yields}J/{psi}K{sup {+-}} and [+2.0{+-}9.1(stat){+-}1. 0(syst)]% for B{sup {+-}}{yields}{psi}(2S)K{sup {+-}} .

Abstract: We report results of a search for the rare radiative decay B(bar sign){sup 0}{yields}D{sup *0} {gamma} . Using 9.66x10{sup 6} BB(bar sign) meson pairs collected with the CLEO detector at the Cornell Electron Storage Ring, we set an upper limit on the branching ratio for this decay of 5.0x10{sup -5} at 90% C.L. This provides evidence that the anomalous enhancement is absent in W -exchange processes and that weak radiative B decays are dominated by the short-distance b{yields}s{gamma} mechanism in the standard model.

Using 9.6x10{sup 6} BB meson pairs collected with the CLEO detector, we have observed ten fully reconstructed B{yields}J/{psi}{phi}K candidates, whereas the estimated background is 0.5{+-}0.2 event. We obtain a branching fraction of B(B{yields}J/{psi}{phi}K)=( 8.8{sup +3.5}{sub -3.0}[stat] {+-}1.3[syst])x10{sup -5} . This is the first observed B meson decay requiring the creation of an additional ss quark pair. (c) 2000 The American Physical Society.

Abstract: We have searched for the rare decays of the eta prime meson to e+ e- eta, e+ e- pizero, e+ e- gamma, and e mu in hadronic events at the CLEO II detector. The search is conducted on 4.80 fb^-1 of e+ e- collisions at the Cornell Electron Storage Ring. We find no signal in any of these modes, and set 90% confidence level upper limits on their branching fractions of 2.4 X 10^-3, 1.4 X 10^-3, 0.9 X 10^-3, and 4.7 X 10^-4, respectively. We also investigate the Dalitz plot of the common decay of the eta prime to pi+ pi- eta. We fit the matrix element with the Particle Data Group parameterization and find Re(alpha) = -0.021 +- 0.025, where alpha is a linear function of the kinetic energy of the eta.

Abstract: Using 13.7 fb(-1) of data recorded by the CLEO detector at Cornell Electron Storage Ring, we report evidence of two new charmed baryons: one decaying into Xi(0')(c)pi(+) with the subsequent decay Xi(0')(c)-->Xi(0)(c)gamma, and its isospin partner decaying into Xi(+')(c)pi(-) followed by Xi(+')(c)-->Xi(+)(c)gamma. We measure the following mass differences for the two states: M(Xi(0)(c)gammapi(+))-M(Xi(0)(c)) = 318.2+/-1.3+/-2.9 MeV and M(Xi(+)(c)gammapi(-))-M(Xi(+)(c)) = 324.0+/-1.3+/-3.0 MeV. We interpret these new states as the J(P) = 1 / 2(-) Xi(c1) particles, the charmed-strange analogs of the Lambda(+)(c1)(2593).

Abstract: Using a sample of $3.3\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B$-meson decays collected with the CLEO detector at the Cornell Electron Storage Ring, we have studied ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{0}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$ and ${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$ decays, where ${\ensuremath{\ell}}^{\ensuremath{-}}$ can be either ${e}^{\ensuremath{-}}$ or ${\ensuremath{\mu}}^{\ensuremath{-}}$. We distinguish $B\ensuremath{\rightarrow}D\ensuremath{\ell}\ensuremath{\nu}$ from other $B$ semileptonic decays by examining the net momentum and energy of the particles recoiling against $D\ensuremath{-}\ensuremath{\ell}$ pairs. We find $\ensuremath{\Gamma}(B\ensuremath{\rightarrow}D\ensuremath{\ell}\ensuremath{\nu})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}(14.1\ifmmode\pm\else\textpm\fi{}1.0\ifmmode\pm\else\textpm\fi{}1.2){\mathrm{ns}}^{\ensuremath{-}1}$ and derive branching fractions for ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{0}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$ and ${\overline{B}}^{0}\ensuremath{\rightarrow}{D}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}\overline{\ensuremath{\nu}}$ of $(2.32\ifmmode\pm\else\textpm\fi{}0.17\ifmmode\pm\else\textpm\fi{}0.20)%$ and $(2.20\ifmmode\pm\else\textpm\fi{}0.16\ifmmode\pm\else\textpm\fi{}0.19)%$, respectively, where the uncertainties are statistical and systematic. We also investigate the $B\ensuremath{\rightarrow}D\ensuremath{\ell}\ensuremath{\nu}$ form factor and the implication of the result for $|{V}_{\mathrm{cb}}|$.

Abstract: We have observed four fully reconstructed B{sup 0}{r_arrow}D{sup {asterisk}+}D{sup {asterisk}{minus}} candidates in 5.8{times}10{sup 6} {Upsilon}(4S){r_arrow}B{ovr B} decays recorded with the CLEO detector. The background is estimated to be 0.31{plus_minus}0.10 thinspthinspevents. The probability that the background could produce four or more signal candidates with the observed distribution among D{sup {asterisk}+} and D{sup {asterisk}{minus}} decay modes is 1.1{times}10{sup {minus}4} . The measured decay rate, B(B{sup 0}{r_arrow}D{sup {asterisk}+}D{sup {asterisk} {minus}})=[6.2{sup +4.0}{sub {minus}2.9}( stat){plus_minus}1.0(syst) ]{times}10{sup {minus}4} , is large enough for this decay mode to be of interest for the measurement of a time-dependent CP asymmetry. {copyright} {ital 1999} {ital The American Physical Society}

Abstract: We report the first observation of two narrow charmed strange baryons decaying to {Xi}{sup +}{sub c}{gamma} and {Xi}{sup 0}{sub c}{gamma} , respectively, using data from the CLEO II detector at the Cornell Electron Storage Ring. We interpret the observed signals as the {Xi}{sup +{prime}}{sub c}thinsp( c{l_brace}su{r_brace}) and {Xi}{sup 0{prime}}{sub c}thinsp( c{l_brace}sd{r_brace}) , the symmetric partners of the well-established antisymmetric {Xi}{sup +}{sub c}thinsp(c[ su]) and {Xi}{sup 0}{sub c}thinsp(c[ sd]) . The mass differences M({Xi}{sup +{prime}}{sub c}){minus}M( {Xi}{sup +}{sub c}) and M({Xi}{sup 0{prime}}{sub c}){minus}M( {Xi}{sup 0}{sub c}) have been measured to be 107.8{plus_minus}1.7{plus_minus}2.5 and 107.0{plus_minus}1.4{plus_minus}2.5 MeV /c{sup 2} , respectively. {copyright} {ital 1999} {ital The American Physical Society }

Abstract: The decay {tau}{sup {minus}}{r_arrow}K{sup {asterisk}{minus}}{eta}{nu}{sub {tau}} has been observed with the CLEOthinspthinspII detector. The K{sup {asterisk}{minus}} is reconstructed in two decay channels, K{sup {asterisk}{minus}}{r_arrow}K{sub S}{pi}{sup {minus}}{r_arrow} {pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}} and K{sup {asterisk}{minus}}{r_arrow}K{sup {minus}}{pi}{sup 0} . The {eta} is reconstructed from the decay {eta}{r_arrow}{gamma}{gamma} . The measured branching fraction is B({tau}{sup {minus}}{r_arrow}K{sup {asterisk}{minus}} {eta}{nu}{sub {tau}})=(2.9{plus_minus} 0.8{plus_minus}0.4){times}10{sup {minus}4} . We also measure the inclusive branching fractions without requiring the K{sup {asterisk}} resonance, B({tau}{sup {minus}}{r_arrow}K{sub S}{pi}{sup {minus}}{eta}{nu}{sub {tau}})=(1.10 {plus_minus}0.35{plus_minus}0.11){times}10{sup {minus}4} and B({tau}{sup {minus}}{r_arrow}K{sup {minus}}{pi}{sup 0}{eta}{nu}{sub {tau}})=(1.77 {plus_minus}0.56{plus_minus}0.71){times}10{sup {minus}4} . The results indicate that the K{sup {asterisk}{minus}} resonance dominates the K{sub S}{pi}{sup {minus}} mass spectrum. {copyright} {ital 1999} {ital The American Physical Society}

No evidence for a signal is found in 4.77fb−1 of data and a 95% C.L. upper limit on [τγγBπ+π−]fJ(2220) of 2.5 eV is set. If this result is combined with the BES Collaboration's measurement of fJ(2220)→π+π− in radiative J/Ψ decay and the recent CLEO result for [τγγBK0SK0S]fJ(2220), a 95% C.L. lower limit on the stickiness of 102 is obtained. This result for the stickiness provides further support for a substantial neutral parton content in the fJ(2220). © 1998 The American Physical Society.

Abstract: We report the first observation of B{r_arrow}{eta}{sup {prime}}X transitions with high momentum {eta}{sup {prime}} mesons. We observe 39.0{plus_minus}11.6 B decay events with 2.0{lt}p{sub {eta}{sup {prime}}}{lt}2.7 GeV/c , the high momentum region where background from b{r_arrow}c processes is suppressed. We discuss the physical interpretation of the signal, including the possibility that it is due to b{r_arrow}sg{sup {asterisk}} transitions. Given that interpretation, we find B(B{r_arrow}{eta}{sup {prime}}X{sub s} )=[6.2{plus_minus}1.6(stat){plus_minus} 1.3(syst){sup +0.0}{sub {minus}1.5} (bkg)]{times}10{sup {minus}4} for 2.0{lt}p{sub {eta}{sup {prime}}}{lt}2.7 GeV/c . {copyright} {ital 1998} {ital The American Physical Society }

Abstract: We have searched for two-body charmless decays of B mesons to purely hadronic exclusive final states including $\omega$ or $\phi$ mesons using data collected with the CLEO II detector. With this sample of $6.6 \times 10^6$ B mesons we observe a signal for the $\omega K^+$ final state, and measure a branching fraction of B($B^+ \to \omega K^+$) = 1.5 +0.7 -0.6 +-0.2 $\times 10^{-5}$. We also observe some evidence for the $\phi K^*$ final state, and upper limits are given for 22 other decay modes. These results provide the opportunity for studies of theoretical models and physical parameters.

From the measured branching ratio B(D^(*+)→D^+γ)/B(D^(*+)→D^+π^0) = 0.055±0.014±0.010 we find B(D^(*+)→D^+γ) = 0.017±0.004±0.003, where the first uncertainty is statistical and the second is systematic. We also report the highest precision determination of the remaining D^(*+) branching fractions.

Abstract: Using 3.1 fb$^{-1}$ of data accumulated at the $\Upsilon$(4S) by the CLEO-II detector, corresponding to 3.3 million $B\bar{B}$ pairs, we have searched for the color-suppressed $B$ hadronic decay processes: $\bar{B}^0 \to D^0 (D^{*0}) X^0$, where $X^0$ is a light neutral meson $\pi^0$, $\rho^0$, $\eta$, $\eta'$ or $\omega$. No obvious signal is observed. We set 90 % C.L. upper limits on these modes, varying from $1.2 \times 10^{-4}$ for $\bar{B}^0 \to D^0 \pi^0$ to $1.9 \times 10^{-3}$ for $\bar{B}^0 \to D^{*0} \eta'$.

Abstract: In a sample of 6.6×10^6 produced B mesons we have observed decays B→η′K, with branching fractions B(B^+→η′K^+) = (6.5_(-1.4)^(+1.5)±0.9)×10^(-5) and B(B^0→η′K^0) = (4.7_(-2.0)^(+2.7)±0.9)×10^(-5). We have searched with comparable sensitivity for 17 related decays to final states containing an η or η′ meson accompanied by a single particle or low-lying resonance. Our upper limits for these constrain theoretical interpretations of the B→η′K signal.

Abstract: We present a measurement of the absolute branching fraction for D^0→K^-π^+ using the reconstruction of the decay chain B →D^(*+)Xl^-ν , D^(*+)→D^0π^+ where only the lepton and the low-momentum pion from the D^(*+) are detected. With data collected by the CLEO II detector at the Cornell Electron Storage Ring, we have determined B(D^0→K^-π^+) = [3.81±0.15(stat)±0.16(syst)]%.

Abstract: We have searched for the decay $\stackrel{\ensuremath{\rightarrow}}{B}{D}_{s1}^{+}(2536)X$ and measured an upper limit for the inclusive branching fraction of $\mathcal{B}(\stackrel{\ensuremath{\rightarrow}}{B}{D}_{s1}^{+}X)l0.96%$ at the 90% confidence level. This limit is small compared with the total expected $\stackrel{\ensuremath{\rightarrow}}{B}{D}^{(*)}{D}^{(*)}\mathrm{KX}$ rate. Assuming factorization, the ${D}_{s1}^{+}$ decay constant is constrained to be ${f}_{{D}_{s1}^{+}}$114 MeV at the 90% confidence level, at least 2.5 times smaller than that of ${D}_{s}^{+}$.

Abstract: The decays ϒ(4S)→BB , followed by B→D^*π and D^*→Dπ, permit reconstruction of all kinematic quantities that describe the sequence without reconstruction of the D, with reasonably low backgrounds. Using an integrated e^+e^- luminosity of 3.1 fb^(-1) accumulated at the ϒ(4S) by the CLEO-II detector, we report measurements of B(B ^0→D^(*+)π^-) = (2.81±0.11±0.21±0.05)×10^(-3) and B(B-→D^*0π^-) = (4.34±0.33±0.34±0.18)×10^(-3).

Abstract: Using the CLEO detector at the Cornell Electron Storage Ring, we have made a measurement of R≡σ(e^+e^-→hadrons)/σ(e^+e^-→μ^+μ^-)=3.56±0.01±0.07 at √s=10.52 GeV. This implies a value for the strong coupling constant of α_s(10.52 GeV)=0.20±0.01±0.06, or α_s(MZ)=0.13±0.005±0.03.
