The Rho GTPase activating protein 26 (ARHGAP26) gene has been reported to be associated with neuropsychiatric diseases and neurodegenerative diseases including Parkinson's disease. We examined whether the ARHGAP26 gene is associated with Alzheimer's disease (AD) and/or cardiovascular disease (CVD). Multivariable logistic regression model was used to examine the associations of 154 single nucleotide polymorphisms (SNPs) within the ARHGAP26 gene with AD and CVD using the Alzheimer's Disease Neuroimaging Initiative 1 (ADNI-1) cohort. Fourteen SNPs were associated with AD (top SNP rs3776362 with p = 3.43 × 10

Older lesbian, gay, bisexual, and transgender (LGBT) persons face many challenges in aging, including coping with life-long discrimination and encountering family and others who are not supportive of their identities and relationships. Members of this population who reside in small towns and rural areas face even more challenges in older adulthood. This article presents a case study of an older woman who is questioning her sexual orientation and discusses her experiences in the context of aging in a rural community. The article also addresses the historical context in which older LGBT people came of age as well as health issues that impact them. In addition, recommendations are offered for improving provider services with LGBT individuals.

Dilute alloys of bismuth in gallium (98-99% at.) are known from theoretical calculations and x-ray scattering to display a strong segregation of bismuth atoms at the surface, a monatomic layer of bismuth appearing because of the lower surface tension of the Bi compared to the Ga. Rutherford backscattering (RBS) spectra from 2 MeV He+ and 2 MeV C+ on a dilute alloy of Ga(99.8% at.):Bi(0.2% at.) have been measured. A distinct peak in the RBS spectra, corresponding to scattering from the surface of the alloy, is consistent with a monatomic layer of bismuth on the alloy over a range of temperatures for which the alloy is a liquid to room temperature where it is a solid. The peak is not observed when the alloy is cooled to a solid state and this observation is thought to be due to the irregular surface structure of the alloy. Bismuth is also observed to be uniformly distributed throughout the gallium host for the depths studied at these beam energies. Some oxide may be present due to the 10-7 Torr vacuum and the long spectral integration times.

Objective Develop and gain feedback on a food insecurity toolkit for higher education institutions to provide food insecurity programming on campus that will promote a food-secure campus environment. Methods A search of the literature was completed by 2 researchers to develop the toolkit. The toolkit was assessed using an online 27 item open- and close-ended survey. One hundred twenty-six stakeholders from 106 land grant institutions were contacted to provide perceptions of the developed toolkit, including usefulness, barriers to application, and recommendations for improvement. Results Thirty stakeholders from 27 institutions responded. Thematic analysis of feedback covered 4 main topics: layout, overall content, initiatives, and application. Eight themes emerged: visual appeal, organization, value, provoking, comprehensive, barriers, collaboration, and efficiency. Corrections and recommendations were provided for each topic. Conclusions And Implications The themes derived encompassed the objective of the toolkit. This toolkit serves as a resource that can be utilized by student leaders, clubs or organizations, campus stakeholders, or administrators to begin a food security initiative on campus.

This chapter explores how Matthew Shepard’s legacy has shaped federal policy and LGBTQ rights in rural United States while highlighting the shortcomings of the politics of visibility when it comes to the protection of victims. Morrow traces the changes in the annual FBI hate crimes statistics from 1997 (the year prior to Shepard’s death) to the present and provides an analysis of the trends in the commission of these crimes over time. Analysis of hate crime data from “more rural states” such as Maine, Vermont, South Dakota, West Virginia, and Montana show that there has not been a decrease in the number of hate crimes reported since 1998, despite the attention Shepard’s murder received. Morrow found that the numbers of reported sexual orientation–motivated hate crimes in these states was elevated from 2006 to 2008, the years during which President Barak Obama was in office. The numbers rose again in 2010, after the federal Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act was signed into law by President Obama and added protections based on gender identity and disability to the Hate Crimes Statistics Act of 1990.

To evaluate the achievement of HbA1c targets in patients with type 2 diabetes mellitus in specialist practice.This audit was undertaken by members of the S4S Diabetes Informatics Group (DINGO), a consortium of Australian endocrinologists in private practice who contribute de-identified data from their electronic medical record, Audit 4 (Software 4 Specialists, S4S, AustraliaNew Zealand) for audit purposes. Data from patients with type 2 diabetes was extracted. Inclusion criteria were: initial age70years, baseline HbA1c7% (53mmol/mol), with at least another HbA1c recorded in the next 2years, and a minimum of 2years follow-up. Data was analysed using a linear mixed effects model.Of the 4796 patients in the dataset with type 2 diabetes mellitus, 1379 patients fulfilled inclusion criteria. The median age at initial consultation was 57 (49-64)years. The median baseline HbA1c was 8.7 (7.8-9.8)% (72mmol/mol). There was a 1.0% reduction in HbA1c to 7.7 (7.1-8.6)% (61mmol/mol) (p0.0001) in the first 3-6months following referral, after which there were no further changes. The initial reduction was maintained with minimal loss of control at 4years. By 3-6months, 24% of patients achieved the target HbA1c.Referral of patients with type 2 diabetes to an endocrinologist reduces HbA1c, and the effect is sustained over the medium term; however only a minority of patients reach targets.

• Objective: Critically ill patients are at high risk of developing pressure ulcers (PU), with the sacrum and heels being highly susceptible to pressure injuries. The objective of our study was to evaluate the clinical effectiveness of a new multi-layer, self-adhesive soft silicone foam heel dressing to prevent PU development in trauma and critically ill patients in the intensive care unit (ICU). • Method: A cohort of critically ill patients were enrolled at the Royal Melbourne Hospital. Each patient had the multi-layer soft silicone foam dressing applied to each heel on admission to the emergency department. The dressings were retained with a tubular bandage for the duration of the patients' stay in the ICU. The skin under the dressings was examined daily and the dressings were replaced every three days. The comparator for our cohort study was the control group from the recently completed Border Trial. • Results: Of the 191 patients in the initial cohort, excluding deaths, loss to follow-up and transfers to another ward, 150 patients were included in the final analysis. There was no difference in key demographic or physiological variables between the cohorts, apart from a longer ICU length of stay for our current cohort. No PUs developed in any of our intervention cohort patients compared with 14 patients in the control cohort (n=152; p• Conclusion: We conclude, based on our results, that the multi-layer soft silicone foam dressing under investigation was clinically effective in reducing ICU-acquired heel PUs. The findings also support previous research on the clinical effectiveness of multi-layer soft silicone foam dressings for PU prevention in the ICU.

OBJECTIVES: Many universities are starting initiatives on campus to support food insecure students in receiving nutritious food. However, there is no comprehensive resource of these initiatives to help guide universities in starting a program on campus. The objective of this study is to describe the development and evaluation of a toolkit that can assist higher education institutions in promoting a campus environment, providing adequate resources for food insecure students. METHODS: The toolkit development was guided by the basis of the Normalization Process Theory (NPT) to evaluate factors that could facilitate or inhibit initiative success on campus. A review of literature was undertaken by two independent reviewers to gather all peer reviewed and grey literature on food insecurity programs currently available on college campuses in the United States. Findings were compiled into a toolkit that contained six initiative chapters: food pantries, campus gardens, farmers markets, dining and recovery programs, mobile applications, and policy initiatives. The toolkit was evaluated by experts from land-grant universities who work with food insecurity issues (n = 126). Experts completed a 27-question survey to determine demographics, perceptions of food insecurity and evaluation of specific toolkit components. Descriptive statistics and frequency analyses were performed on quantitative data and content analysis was used to analyze qualitative data. RESULTS: Thirty experts (23.8% response rate) completed the evaluation survey. Evaluation feedback covered four main topics: layout, overall content, initiatives, and application. Eight themes emerged from the coding and categorization of responses. They were visual appeal, organization, value, provoking, comprehensive, barriers, collaboration, and efficiency. Corrections and recommendations were provided for each topic. CONCLUSIONS: The themes derived from expert feedback encompassed the initial objective of the toolkit. This toolkit serves as a comprehensive resource that can be utilized by student leaders, clubs or organizations, campus stakeholders or administrators to begin a food security initiative on campus to promote student well-being. FUNDING SOURCES: Primary funding is from the West Virginia Agricultural and Forestry Experiment Station WVA00689 and WVA00721. The first author is supported by the National Institute of General Medical Sciences T32 grant (GM081741).

Diabetic ketoacidosis and hyperglycaemic hyperosmolar syndrome are rare, but potentially fatal complications of antipsychotic-associated hyperglycaemia. The mechanisms for this remain unclear, but are probably multifactorial. The suggested reasons include drug-induced weight gain and adiposity, development of the metabolic syndrome, antagonism of serotonin (5-hydroxytryptamine) receptors, drug-induced leptin resistance, dyslipidaemia mediated pancreatic beta-cell damage and hepatocyte transcription factor dysregulation. Patients with schizophrenia are known to be at a higher genetic risk of developing diabetes mellitus and cardiovascular disease. This review emphasizes a rare case of hyperosmolar hyperglycaemic syndrome in a young man with schizophrenia and discusses proposed mechanisms for the development of antipsychotic-associated diabetes mellitus.

The KRIA water treatment system works by charging water with the superoxide radical (O2-), which is electrochemically generated from oxygen in the atmosphere. At the injection site, both cavitation and microbubble reactions may also occur. A review of the literature indicates that superoxide is a relatively weak radical, but it can work both oxidatively and reductively. A review of the literature also showed that superoxide can transform ch

Coming out to families is a major milestone event for many lesbian and gay people. Social work intervention can be an important support for gay and lesbian people who are preparing to come out to their families. This article reviews the literature related to coming out to families, and proposes the following ten guidelines for social work intervention with clients who are considering coming out to family members: evaluate the client's social context; assess the client's level of gay/lesbian identity development; develop a client knowledge base related to gay and lesbian issues; develop a social support system; engage practice experiences before coming out to families; determine the availability of supportive family allies; choose language and terminology appropriate for the receiver of the news; select the method of information delivery; structure the timing of coming out; and, prepare the client for upheaval.

The study examines the relations of self-concept, self-esteem, and racial preference to the academic achievement of African American preschool children. The children were 49 to 63 months of age and enrolled in a Head Start program. Three self-perception measures were obtained for each child, and a measure of academic achievement was obtained yielding 2 scores: a Knowledge Cluster Score and a Skills Cluster Score. Regression analyses indicated that academic self-esteem accounted for a significant amount of the variance in both the Knowledge and Skills Cluster Scores of the children. Racial attitude was also a significant predictor of Knowledge Cluster scores, and self-concept predicted Skills Cluster scores; however, these measures accounted for less variance in achievement than did academic self-esteem. Findings suggest that the development of academic self-esteem is important for the school achievement of minority children.

The relationship between the CFO and the audit committee has changed from oftentimes one of minimal contact to almost daily interaction as a result of the Sarbanes‐Oxley legislation. This is probably for the best, as the remoteness of audit committees in the past likely contributed to at least some of the corporate dysfunction we have seen in recent years.

We present a clinical pathological review of vitreous amyloidosis in a case of familial amyloidotic polyneuropathy, type I. Vitreous opacification was the first manifestation of disease in the proband, who was successfully treated with vitrectomy. The eyes were obtained at autopsy after the patient died from an unrelated cause, and the histopathology is presented here. Analysis of DNA from the pathology specimen revealed the most commonly reported transthyretin mutation, Val30Met. The classification of systemic and ocular amyloidosis as well as the genetics of familial amyloidotic polyneuropathy are briefly reviewed.

Using data collected in the region of the [Upsilon](4[ital S]) resonance with the CLEO II detector operating at the Cornell Electron Storage Ring, we report on evidence for the production of [Sigma][sub [ital c]][sup ++] and [Sigma][sub [ital e]][sup 0] baryons in [ital B] decays, with [Sigma][sub [ital c]][r arrow][Lambda][sub [ital c]][sup +][pi]. This observation is based on 77[plus minus]19[Sigma][sub [ital c]][sup ++] and 76[plus minus]21[Sigma][sub [ital c]][sup 0] candidates from [ital B] decays. We find the product branching fractions [ital scrB]([ital [bar B]][r arrow][Sigma][sub [ital c]][ital X])[ital scrB]([Lambda][sub [ital c]][sup +][r arrow][ital pK][sup [minus]][pi][sup +]) for [Sigma][sub [ital c]]=[Sigma][sub [ital c]][sup ++], [Sigma][sub [ital c]][sup 0], and [Sigma][sub [ital c]][sup +] to be (2.1[plus minus]0.8[plus minus]0.7)[times]10[sup [minus]4], (2.3[plus minus]0.8[plus minus]0.7)[times]10[sup [minus]4], and less than 4.8[times]10[sup [minus]4] at 90% confidence level, respectively. A study of the [Sigma][sub [ital c]][sup ++] and [Sigma][sub [ital c]][sup 0] momentum spectra indicates that [ital B] decays to two-body final states with [Sigma][sub [ital c]] are suppressed.

We have fully reconstructed decays of both B0 and B- Mesons into final states containing either D, D*, D**, Psi, Psi', or Chi_{c1} mesons. This allows us to obtain new results on many physics topics including branching ratios, tests of the factorization hypothesis, color suppression, resonant substructure, and the B- - B0 mass difference., Comment: 37 pages. uuencoded compressed postscript (process with uudecode, then gunzip). 31 postscript figures available on request.

We present a measurement of [Gamma]([ital D][sub [ital s]][sup +][r arrow][mu][sup +][nu])/[Gamma]([ital D][sub [ital s]][sup +][r arrow][phi][pi][sup +])= 0.245[plus minus]0.052[plus minus]0.074. Using this ratio and [ital scrB]([ital D][sub [ital s]][sup +][r arrow][phi][pi][sup +])=(3.7[plus minus]0.9)% we extract [ital f][sub [ital D][ital s]]=344[plus minus]37[plus minus]52[plus minus]42 MeV, where the last error is due to the uncertainty in the [ital D][sub [ital s]][sup +][r arrow][phi][pi][sup +] absolute branching ratio. This result is larger than most theoretical predictions.

We have observed the previously unseen decay modes Λπ+π0, Σ0π+π0 and Σ0π−π+π+ of the charmed baryon Λc+, as well as Λc+→Σ0π+ observed previously by ARGUS. The branching ratios for these four decay modes relative to Λc+→pK−π+ are measured to be 0.73 ±0.09± 0.16, 0.36 ±0.09±0.10, 0.21±0.05±0.05, and 0.21±0.02 ±0.04, respectively. Using the recent CLEO measurement of the branching ratio for Λc+→pK− π+, these modes account for 6% of Λc+ decays.

Using the CLEO II data sample, with an integrated luminosity of 1.8 fb[sup [minus]1] at and near the [Upsilon](4[ital S]) resonance, we have observed a signal for [ital D][sup 0][r arrow][ital K][sup +][pi][sup [minus]], which could be due to either [ital D][sup 0][ital [bar D]][sup 0] mixing or doubly Cabibbo suppressed decay, or a combination of the two. We find [ital scrB]([ital D][sup 0][r arrow][ital K][sup +][pi][sup [minus]])/[ital scrB]([ital D][sup 0][r arrow][ital K][sup [minus]][pi][sup +])=0.0077[plus minus]0 .0025(stat) [plus minus]0.0025(syst).

Using the CLEO II detector at CESR we observe 500 Λ l + pairs consistent with the semileptonic decay Λc+ → λ+ν We measure σ(e + e − → Λ + c X) · B(Λ + c → Λ l + ν l ) = 4.77±0.25±0.66 pb . Combining with the charm semileptonic width and the lifetime of the Λc we also obtain B(Λ+c → pK−π+). We find no evidence for Λ l + ν l final states in which there are additional Λ+c decay products. We measure the decay asymmetry parameter of Λ+c → Λe+νe to be αΛc = −0.89+0.17+0.09−0.11−0.05.

Using the CLEO II detector and a sample of 955 000 [Upsilon](4S) decays we have confirmed charmless semileptonic decays of [ital B] mesons. In the momentum interval 2.3--2.6 GeV/[ital c] we observe an excess of 107[plus minus]15[plus minus]11 leptons, which we attribute to [ital b][r arrow][ital ul][nu]. This result yields a model-dependent range of values for [vert bar][ital V][sub [ital u][ital b]]/[ital V][sub [ital c][ital b]][vert bar] that is lower than has been obtained in previous studies. For the inclusive spectator model of Altarelli [ital et] [ital al]. we find [vert bar][ital V][sub [ital u][ital b]]/[ital V][sub [ital c][ital b]][vert bar]=0.076[plus minus]0.008. Models that describe [ital b][r arrow][ital ul][nu] with a limited set of exclusive final states give [vert bar][ital V][sub [ital u][ital b]]/[ital V][sub [ital c][ital b]][vert bar]=0.06[minus]0.10.

We report results from a search for the decays ${\mathit{B}}^{0}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\pi}}}^{+}$${\mathrm{\ensuremath{\pi}}}^{\mathrm{\ensuremath{-}}}$, ${\mathit{B}}^{0}$\ensuremath{\rightarrow}${\mathit{K}}^{+}$${\mathrm{\ensuremath{\pi}}}^{\mathrm{\ensuremath{-}}}$, and ${\mathit{B}}^{0}$\ensuremath{\rightarrow}${\mathit{K}}^{+}$${\mathit{K}}^{\mathrm{\ensuremath{-}}}$. We find 90% confidence level upper limits on the branching fractions, ${\mathit{B}}_{\mathrm{\ensuremath{\pi}}\mathrm{\ensuremath{\pi}}}$2.9\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}5}$, ${\mathit{B}}_{\mathit{K}\mathrm{\ensuremath{\pi}}}$2.6\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}5}$, and ${\mathit{B}}_{\mathit{K}\mathit{K}}$0.7\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}5}$. While there is no statistically significant signal in the individual modes, the sum of ${\mathit{B}}_{\mathrm{\ensuremath{\pi}}\mathrm{\ensuremath{\pi}}}$ and ${\mathit{B}}_{\mathit{K}\mathrm{\ensuremath{\pi}}}$ exceeds zero with a significance of more than 4 standard deviations, indicating that we have observed charmless hadronic B decays.

Using 1.16 × 106 B B events collected at the γ(4S) resonance by the CLEO Collaboration at the Cornell Electron Storage Ring (CESR), we have searched for decays of B mesons to exclusive two-body hadronic final states including a Ds+ or a D s ∗+ meson. We obtain the 90% confidence level upper limit β (B → D s (∗)+ π − + D s ∗ +p − + D s (∗)+ π 0 + D s (∗)+ η + D s (∗)+ p 0 + D s (∗)+ (ω) × β(D s + → φπ + ) −5 . We have also searched for the W-exchange decays, B 0 → D s (∗)− K (∗)+ .

We observe the [Sigma][sub [ital c]][sup +] baryon decaying to [Lambda][sub [ital c]][sup +][pi][sup 0] and measure the mass difference [ital M]([Sigma][sub [ital c]][sup +])[minus][ital M]([Lambda][sub [ital c]][sup +]) to be 168.5[plus minus]0.2 MeV/[ital c][sup 2]. We also measure the mass differences [ital M]([Sigma][sub [ital c]][sup ++])[minus][ital M]([Lambda][sub [ital c]][sup +]) and [ital M]([Sigma][sub [ital c]][sup 0])[minus][ital M]([Lambda][sub [ital c]][sup +]) with improved precision and determine the isospin mass splittings [ital M]([Sigma][sub [ital c]][sup ++])[minus][ital M]([Sigma][sub [ital c]][sup 0]) and [ital M]([Sigma][sub [ital c]][sup +])[minus][ital M]([Sigma][sub [ital c]][sup 0]) to be 1.1[plus minus]0.4[plus minus]0.1 MeV/[ital c][sup 2] and 1.4[plus minus]0.5[plus minus]0.3 MeV/[ital c][sup 2], respectively. Our results indicate that the light quark mass difference does not dominate the isospin mass splitting in [Sigma][sub [ital c]].

We have measured branching ratios for three [Lambda][sub [ital c]] decay modes that have a [Sigma][sup +] in the final state. Two of the observed decay modes, [Lambda][sub [ital c]][r arrow][Sigma][sup +][pi][sup 0] and [Lambda][sub [ital c]][sup +][r arrow][Sigma][sup +][omega], have no external [ital W]-emission amplitudes. Their branching ratios relative to the [ital pK][sup [minus]][pi][sup +] mode are 0.20[plus minus]0.03[plus minus]0.03 and 0.54[plus minus]0.13[plus minus]0.06, respectively. We have also significantly improved the measurement of the branching ratio for the previously observed decay mode [Lambda][sub [ital c]][sup +][r arrow][Sigma][sup +][pi][sup +][pi][sup [minus]]. We find its branching ratio relative to [ital pK][sup [minus]][pi][sup +] to be 0.74[plus minus]0.07[plus minus]0.09.

Using 1.79 ${\mathrm{fb}}^{\mathrm{\ensuremath{-}}1}$ of data recorded by the CLEO II detector we have measured the absolute branching fraction for ${\mathit{D}}^{0}$\ensuremath{\rightarrow}${\mathit{K}}^{\mathrm{\ensuremath{-}}}$${\mathrm{\ensuremath{\pi}}}^{+}$. The angular correlation between the ${\mathrm{\ensuremath{\pi}}}^{+}$ emitted in the decay ${\mathit{D}}^{\mathrm{*}+}$\ensuremath{\rightarrow}${\mathit{D}}^{0}$${\mathrm{\ensuremath{\pi}}}^{+}$, and the jet direction in ${\mathit{e}}^{+}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$\ensuremath{\rightarrow}cc\ifmmode\bar\else\textasciimacron\fi{} events, is used to determine the total number of inclusive ${\mathit{D}}^{0}$ mesons produced from this source. The subsequent reconstruction of the decay chain ${\mathit{D}}^{\mathrm{*}+}$\ensuremath{\rightarrow}${\mathit{D}}^{0}$${\mathrm{\ensuremath{\pi}}}^{+}$,${\mathit{D}}^{0}$\ensuremath{\rightarrow}${\mathit{K}}^{\mathrm{\ensuremath{-}}}$${\mathrm{\ensuremath{\pi}}}^{+}$ allows a measurement of the absolute ${\mathit{D}}^{0}$\ensuremath{\rightarrow}${\mathit{K}}^{\mathrm{\ensuremath{-}}}$${\mathrm{\ensuremath{\pi}}}^{+}$ branching fraction. Correcting for decay radiation in the final state, we find scrB(${\mathit{D}}^{0}$\ensuremath{\rightarrow}${\mathit{K}}^{\mathrm{\ensuremath{-}}}$${\mathrm{\ensuremath{\pi}}}^{+}$)=[3.95\ifmmode\pm\else\textpm\fi{}0.08(stat)\ifmmode\pm\else\textpm\fi{}0.17(syst)]%.

Using a sample of integrated luminosity 1.68 fb−1 collected with the CLEO-II detector at the Cornell Electron Storage Ring, we measure the branching ratios for the dominant exclusive semileptonic decays D → K l ν and D → K ∗ l ν , using charged and neutral D mesons. We also make a precise measurement of the vector form factor for the decay D 0 → K − l + ν , using a sample of 2700 events.

Using the CLEO II detector at CESR we have studied [ital D][sup 0] decays into final states with a [ital [bar K]] [sup 0] or [ital [bar K]] [sup *0], and have measured branching ratios for the decay modes [ital D][sup 0][r arrow]([ital [bar K]] [sup 0]/[ital [bar K]] [sup *0])[pi][sup 0],[eta],[eta][prime]. These results are compared with predictions of various charm decay models, and contributions of final-state interactions are discussed.

We report the measurement of new modes of the charmed baryon ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$ using data recorded by the CLEO II detector at the Cornell Electron Storage Ring. We find branching ratios, relative to ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathit{pK}}^{\mathrm{\ensuremath{-}}}$${\mathrm{\ensuremath{\pi}}}^{+}$, of 0.070\ifmmode\pm\else\textpm\fi{}0.011\ifmmode\pm\else\textpm\fi{}0.011 for ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\Sigma}}}^{+}$${\mathit{K}}^{+}$${\mathit{K}}^{\mathrm{\ensuremath{-}}}$, 0.069\ifmmode\pm\else\textpm\fi{}0.023\ifmmode\pm\else\textpm\fi{}0.016 for ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}\ensuremath{\Sigma}\ensuremath{\varphi}, 0.078\ifmmode\pm\else\textpm\fi{}0.013\ifmmode\pm\else\textpm\fi{}0.013 for ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\Xi}}}^{0}$${\mathit{K}}^{+}$, and 0.053\ifmmode\pm\else\textpm\fi{}0.016\ifmmode\pm\else\textpm\fi{}0.010 for ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\Xi}}}^{\mathrm{*}0}$${\mathit{K}}^{+}$. These measurements indicate that W-exchange diagrams contribute to ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$ decay. We have also made a new measurement of the previously found mode ${\mathrm{\ensuremath{\Lambda}}}_{\mathit{c}}^{+}$\ensuremath{\rightarrow}${\mathrm{\ensuremath{\Xi}}}^{\mathrm{\ensuremath{-}}}$${\mathit{K}}^{+}$${\mathrm{\ensuremath{\pi}}}^{+}$.

Using data from CLEO II at the Cornell Electron Storage Ring we provide a new measurement of the branching fraction for [ital D][sup 0][r arrow][pi][sup +][pi][sup [minus]], and we present the first measurements of [ital D][sup 0][r arrow][pi][sup 0][pi][sup 0] and of [ital D][sup +][r arrow][pi][sup +][pi][sup 0], which is due to an isospin changing [Delta][ital I]=3/2 transition. From these data we extract the ratio of isospin amplitudes [vert bar][ital A][sub 2]/[ital A][sub 0][vert bar], and the cosine of the relative phase [delta]=[delta][sub 2][minus][delta][sub 0] between these amplitudes, for [ital D][r arrow][pi][pi] decays. Unlike the situation in kaon decay where [ital A][sub 2] is strongly suppressed, we find [vert bar][ital A][sub 2]/[ital A][sub 0][vert bar]=0.72[plus minus]0.13[plus minus]0.11 and cos[delta]=0.14[plus minus]0.13[plus minus]0.09.

The decay [tau][sup [minus]][r arrow][pi][sup [minus]][pi][sup +][pi][sup [minus]]2[pi][sup 0][nu][sub [tau]] has been observed in [ital e][sup +][ital e[minus]] annihilation using the CLEO II detector at the Cornell Electron Storage Ring. In a data sample collected at [radical][ital s] [similar to]10.6 GeV, 668[plus minus]38 decay candidates have been identified by exclusively reconstructing two [pi][sup 0]'s accompanying three charged particles, which are assumed to be pions. Normalizing to the number of [tau] pairs detected with one charged particle recoiling against three charged particles, this yields a branching ratio of [ital B][sub 3[pi]2[pi]][sup 0]=(0.48[plus minus]0.04[plus minus]0.04)%.

We have measured the [ital B][sup 0][ital [bar B]0] mixing probability, [chi][sub [ital d]], using a sample of 965 000 [ital B[bar B]] pairs from [Upsilon](4[ital S]) decays. Counting dilepton events, we find [chi][sub [ital d]]=0.157[plus minus]0.016[plus minus]0.018[sub [minus]0.021][sup +0.028]. Using tagged [ital B][sup 0] events, we find [chi][sub [ital d]]=0.149[plus minus]0.023[plus minus]0.019[plus minus]0.010. The first (second) error is statistical (systematic). The third error reflects a [plus minus]15% uncertainty in the assumption, made in both cases, that charged and neutral [ital B] pairs contribute equally to dilepton events. We also obtain a limit on the [ital CP] impurity in the [ital B][sub [ital d]][sup 0] system, [vert bar]Re([epsilon][sub [ital B]][sup 0])[vert bar][lt]0.045 at 90% C.L.

We have observed the decays [ital B][sup 0][r arrow][ital K][sup *](892)[sup 0][gamma] and [ital B][sup [minus]][r arrow][ital K][sup *](892)[sup [minus]][gamma], which are evidence for the quark-level process [ital b][r arrow][ital s][gamma]. The average branching fraction is (4.5[plus minus]1.5[plus minus]0.9)[times]10[sup [minus]5]. This value is consistent with standard model predictions from electromagnetic penguin diagrams.

A limit on the tau neutrino mass [ital M][sub [nu][tau]] is obtained from a study of tau decays in the reaction [ital e][sup +][ital e[minus]][r arrow][tau][sup +][tau][sup [minus]] at center-of-mass energies [similar to]10.6 GeV. The result is based on an end-point analysis of the invariant mass spectrum of the decay products in the decay modes [tau][sup [minus]][r arrow]3[ital h][sup [minus]]2[ital h][sup +][nu][sub [tau]] and [tau][sup [minus]][r arrow]2[ital h][sup [minus]][ital h+]2[pi][sup 0][nu][sub [tau]]. The data sample used in this analysis contains 1.77[times]10[sup 6] tau pairs, corresponding to an integrated luminosity of 1.92 fb[sup [minus]1], and is substantially larger than previous data samples used to place a limit on [ital M][sub [nu][tau]]. The limit obtained for both five-hadron modes together is 32.6 MeV at 95% C.L.

With the CLEO-II detector at the Cornell Electron Storage Ring, we have measured branching fractions for tau lepton decay into one-prong final states with multiple [pi][sup 0]'s [ital B][sub [ital h][ital n][pi]][sup 0], normalized to the branching fraction for tau decay into one charged particle and a single [pi][sup 0]. We find [ital B][sub [ital h]2[pi]][sup 0]/[ital B][sub [ital h][pi]][sup 0]=0.345[plus minus]0.006[plus minus]0.016, [ital B][sub [ital h]3[pi]][sup 0]/[ital B][sub [ital h][pi]][sup 0]=0.041 [plus minus]0.003[plus minus]0.005, and [ital B][sub [ital h]4[pi]][sup 0]/[ital B][sub [ital h][pi]][sup 0]=0.006[plus minus]0.002[plus minus]0.002.

We present a measurement of the lepton decay asymmetry ${\mathit{A}}_{\mathrm{fb}}$ in the reaction B\ifmmode\bar\else\textasciimacron\fi{}\ensuremath{\rightarrow}${\mathit{D}}^{\mathrm{*}}$${\mathit{l}}^{\mathrm{\ensuremath{-}}}$\ensuremath{\nu}${\mathrm{\ifmmode\bar\else\textasciimacron\fi{}}}_{\mathit{l}}$ using data collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR). The value of ${\mathit{A}}_{\mathrm{fb}}$ confirms that the chirality of the weak interaction is predominantly left-handed in b\ensuremath{\rightarrow}c transitions as expected in the standard model, if it is assumed that the lepton current is also left-handed. Using ${\mathit{A}}_{\mathrm{fb}}$ and the previously determined branching ratio, ${\mathit{q}}^{2}$ distribution, and ${\mathit{D}}^{\mathrm{*}}$ polarization, we obtain the first measurement of the form-factor ratios that are used to describe this semileptonic decay.

A search for the lepton mumber violating decay of the [tau] lepton to the [gamma][mu] final state has been performed with the CLEO II detector at the Cornell [ital e][sup +][ital e[minus]] storage ring CESR. In a data sample that corresponds to an integrated luminosity of 1.55 fb[sup [minus]1], we observe no candidates in the signal region. We thus determine an upper limit of [ital B]([tau][sup [minus]][r arrow][gamma][mu][sup [minus]])[lt]4.2[times]10[sup [minus]6] at 90% confidence level.

The tau lepton electron branching fraction has been measured with the CLEO II detector at the Cornell Electron Storage Ring as [ital B][sub [ital e]]=0.1749[plus minus]0.0014[plus minus]0.0022, with the first error statistical and the second systematic. The measurement involves counting electron-positron annihilation events in which both taus decay to electrons, and normalizing to the number of tau-pair decays expected from the measured luminosity. Detected photons in these events constitute a definitive observation of tau decay radiation.

The decay [tau][sup [minus]][r arrow][nu][sub [tau]][pi][sup [minus]][pi][sup 0][eta] has been observed for the first time using the CLEO-II detector at the Cornell Electron Storage Ring. The measured branching ratio (0.17[plus minus]0.02[plus minus]0.02)%, agrees with the CVC (conserved vector current) prediction based on [ital e][sup +][ital e[minus]][r arrow][pi][sup +][pi][sup [minus]][eta] data. Upper limits on the branching ratios for other [tau] decays to final states including [eta] mesons are improved by an order of magnitude compared to previous measurements.

Using date from [ital e][sup +][ital e[minus]] annihilation into hadrons taken on the [Upsilon](1[ital S]) and continuum, we are able to compare event properties of three-gluon ([ital ggg]) and quark-antiquark ([ital q[bar q]]) decays. By tagging radiative decays of the [Upsilon](3[ital S]) to the [chi][sub [ital b]][sup [prime]] states, we can make comparisons of the [chi][sub [ital b]][sup [prime]] event shapes with continuum and [ital ggg] decays of the [Upsilon](1[ital S]). Contrary to the notion that two-gluon ([ital gg]) events are globally very similar to [ital q[bar q]] jets, we infer from a study of the [chi][sub [ital b]][sup [prime]] ([ital J]=0 or 2) states that [ital gg] event shapes more closely resemble [ital ggg] decays of the [Upsilon](1[ital S]), whereas [ital q[bar q]g] decays of the [chi][sub [ital b]][sup [prime]] ([ital J]=1) state more closely resemble [ital q[bar q]] continuum events in their decay characteristics.

Using the CsI calorimeter of the CLEO-II detector, we have studied exclusive radiative decays of the ϒ(3S) to the χ (2P) states where the final state consists of two photons and two leptons (e + e − or μ + μ − , from either the ϒ(1S) or ϒ(2S)). We observe and measure branching ratios for the J =2 and J =1 χ b (2 3 P J ) states, and set upper limits for the J =0 state.
