This qualitative study aimed to better understand the medication experiences and perspectives of people with PD (PwPD).Patients and Methods: Thirty-two PwPD recruited from five large movement disorder clinics from five US states participated in 1-hour on-line focus groups in 2022. Thematic analysis was used to analyze the data.Results: Four primary themes (subthemes in parentheses) emerged concerning PD medications: (1) medication effectiveness (uncertainty, inconsistent effects, adjusting expectations); (2) medication burden (morning doses, timing challenges, constant reminder); (3) side effects (toleration, treatment, confusion with disease symptoms); and (4) preferences/requests (important attributes, therapy advancement).Conclusion: This study identified four core dimensions associated with PD medications from the perspective of PwPD. Results indicate the need for enhanced communication between providers and patients regarding PD medication to reduce the uncertainties and burden associated with PD medication regimens and promote better health outcomes for PwPD.Keywords: Parkinson’s disease, medication, patient perspective, patient experience

Abstract

Recent reports on high capacities delivered by Li-excess transition-metal oxide cathodes have triggered intense interest in utilizing reversible oxygen redox for high-energy battery applications. To control oxygen electrochemical activities, fundamental understanding of redox chemistry is essential yet has so far proven challenging. In the present study, micrometer-sized Li1.3Nb0.3Mn0.4O2 single crystals were synthesized for the first time and used as a platform to understand the charge compensation mechanism during Li extraction and insertion. We explicitly demonstrate that the oxidation of O2- to On- (0 < n < 2) and O2 loss from the lattice dominates at 4.5 and 4.7 V, respectively. While both processes occur in the first cycle, only the redox of O2-/On- participates in the following cycles. The lattice anion redox process triggers irreversible changes in Mn redox, which likely causes the voltage and capacity fade observed on this oxide. Two drastically different redox activity regions, a single-phase behavior involving only Mn3+/4+ and a two-phase behavior involving O2-/On- (0 ≤ n < 2), were found in LixNb0.3Mn0.4O2 (0 < x < 1.3). Morphological damage with particle cracking and fracturing was broadly observed when O redox is active, revealing additional challenges in utilizing O redox for high-energy cathode development.

Abstract

Olayinka O Shiyanbola,1 Carolyn M Brown,2 Earlise C Ward3 1Division of Social and Administrative Sciences, School of Pharmacy, University of Wisconsin-Madison, Madison, WI, USA; 2Division of Health Outcomes and Pharmacy Practice, College of Pharmacy, University of Texas at Austin, Austin, TX, USA; 3School of Nursing, University of Wisconsin-Madison, Madison, WI, USA Background: Diabetes is disproportionally burdensome among African-Americans (AAs) and medication adherence is important for optimal outcomes. Limited studies have qualitatively examined reasons for nonadherence among AAs with type 2 diabetes, though AAs are less adherent to prescribed medications compared to whites. This study explored the reasons for medication nonadherence and adherence among AAs with type 2 diabetes and examined AAs’ perceived solutions for enhancing adherence. Methods: Forty AAs, age 45–60 years with type 2 diabetes for at least 1 year prior, taking at least one prescribed diabetes medication, participated in six semistructured 90-minute focus groups. Using a phenomenology qualitative approach, reasons for nonadherence and adherence, as well as participants’ perceived solutions for increasing adherence were explored. Qualitative content analysis was conducted. Results: AAs’ reasons for intentional nonadherence were associated with 1) their perception of medicines including concerns about medication side effects, as well as fear and frustration associated with taking medicines; 2) their perception of illness (disbelief of diabetes diagnosis); and 3) access to medicines and information resources. Participants reported taking their medicines because they valued being alive to perform their social and family roles, and their belief in the doctor’s recommendation and medication helpfulness. Participants provided solutions for enhancing adherence by focusing on the roles of health care providers, patients, and the church. AAs wanted provider counseling on the necessity of taking medicines and the consequences of not taking them, indicating the need for the AA community to support and teach self-advocacy in diabetes self-management, and the church to act as an advocate in ensuring medication use. Conclusion: Intentional reasons of AAs with type 2 diabetes for not taking their medicines were related to their perception of medicines and illness. Solutions for enhancing diabetes medication adherence among AAs should focus on the roles of providers, patients, and the church.

Abstract

Raster image correlation spectroscopy (RICS) is a new and novel technique for measuring molecular dynamics and concentrations from fluorescence confocal images. The RICS technique extracts information about molecular dynamics and concentrations from images of living cells taken on commercial confocal systems. Here we develop guidelines for performing the RICS analysis on an analogue commercial laser scanning confocal microscope. Guidelines for typical instrument settings, image acquisition settings and analogue detector characterization are presented. Using appropriate instrument/acquisition parameters, diffusion coefficients and concentrations can be determined, even for highly dynamic dye molecules in solution. Standard curves presented herein demonstrate the ability to detect protein concentrations as low as approximately 2 nM. Additionally, cellular measurements give accurate values for the diffusion of paxillin-enhanced-green fluorescent protein (EGFP), an adhesion adaptor molecule, in the cytosol of the cell and also show slower paxillin dynamics near adhesions where paxillin interacts with immobile adhesion components. Methods are presented to account for bright immobile structures within the cell that dominate spatial correlation functions; allowing the extraction of fast protein dynamics within and near these structures. A running average algorithm is also presented to address slow cellular movement or movement of cellular features such as adhesions. Finally, methods to determine protein concentration in the presence of immobile structures within the cell are presented. A table is presented giving guidelines for instrument and imaging setting when performing RICS on the Olympus FV300 confocal and these guidelines are a starting point for performing the analysis on other commercial confocal systems.

10. The effectiveness of forensic identification evidence in volume crime policing in Australia

Author

Brown, CM

Abstract

Police have endeavoured to establish a knowledge base on effective crime control and prevention practices for specific crime and disorder problems. Volume crime is a generic term that relates to offences such as burglary and motor vehicle theft that have a broad impact across the community. This crime category is difficult to police due to the sheer number of crimes committed daily and, in most instances, there are no witnesses and often, no evidence to identify the offender. Although it is recognised that forensic evidence can assist police in the investigation of volume crimes, little is known about the actual impact of forensic evidence on volume crime investigations, and the ways in which it used by police during the investigative process. Most studies on the effectiveness of forensic science have centred around the use of forensic evidence in the courts with fewer studies examining the effectiveness of forensic science in policing. A gap exists in the police understanding of the most effective ways to use forensic evidence for both investigative and crime reduction purposes. Evidence-based research is needed to provide police organisations with the knowledge and tools to understand how forensic evidence 'works' and how best to use it to address volume crime. This research addresses this gap in knowledge and practice by examining how forensic fingerprint and DNA evidence is used in the investigation of volume crimes in Australia. Through a mixed methods multiphase methodology, combining quantitative and qualitative research, the findings have provided the basis for an evidence-based research approach to the effective use of forensic evidence in volume crime investigations, with recommendations that align with the primary research philosophy of 'what works'. This research project is divided into three phases. The study conducted in Phase One analyses data collected in the first nation-wide study of the impact of fingerprint and DNA evidence on burglaries in Australia. This was one of the first end-to-end studies (i.e. examining the progression of forensic evidence from crime scene to arrest) in the world. Quantitative data were collected from all police organisations in Australia that enabled the benchmarking of performance. The analysis of these data on 8,000 burglary cases found that when fingerprint and DNA evidence led to the identification of a suspect, this resulted in an arrest in more cases than where no forensic evidence was located, yet the data presents considerable variation in performance across Australia. In Phase Two, one of the first Lean studies in forensic services in Australia was conducted in one jurisdiction to identify areas of wasteful work practices in the forensic end-to-end process. The study removed non-value adding practices with the aim of improving the overall delivery of forensic services in the investigation of volume crime cases. This study found that focusing resources in the forensic end-to-end processes on fingerprint and DNA evidence with the best chance of identifying a suspect is the most efficient manner for the investigation of volume crimes. Finally, in Phase Three, a qualitative research study was conducted with police officers from three Australian jurisdictions to explore the ways in which they used fingerprint and DNA evidence in their investigations. This study found that while police investigators considered fingerprint and DNA evidence as essential contributors to the investigative process, this application was hindered by limited knowledge of the strengths and limitations of various forensic evidence types. The analysis of the findings across all three phases of the research revealed that fingerprint and DNA evidence are effective in volume crime investigations in Australia; however, there is considerable variability in performance across and within jurisdictions. Factors affecting this performance were found to include: the lack of a clear and consistent approach to targeting the use of forensic evidence in volume crime investigations and a lack of knowledge on the strengths and weaknesses of different evidence types. For forensic evidence to be used most successfully, the research findings suggest that police take two pathways. First, focusing police and laboratory processes on high probity evidence will provide for greater consistency in the collection, analysis and investigation of forensic evidence, faster provision of forensic results to the investigators, and ultimately result in faster resolution of volume crime investigations. Second, for this to occur requires a collaborative approach to sharing knowledge gained from experience, practice and research between police, forensic providers, and researchers. This will ensure that all personnel participating at any stage of the end-to-end process in the investigation of volume crime can make sense of the forensic evidence and understand how best to use it. The effective use of forensic science in policing, including the effective use of fingerprint and DNA evidence, requires the incorporation of scientific approaches to decision-making into policing. The core argument in this thesis is that through consistently applying the practices that have been scientifically assessed and determined as successful, forensic science can make a positive difference to the efficiency and effectiveness of policing volume crime offending. This requires a change in mindset so that forensic science is viewed beyond its value for prosecutions but as a vital thread that can be woven through the entire range of investigative, intelligence and crime prevention strategies to support effective police performance.

Abstract

The coronavirus disease 2019 (COVID-19) pandemic has demonstrated a clear need for high-throughput, multiplexed and sensitive assays for detecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and other respiratory viruses and their emerging variants. Here, we present a cost-effective virus and variant detection platform, called microfluidic Combinatorial Arrayed Reactions for Multiplexed Evaluation of Nucleic acids (mCARMEN), which combines CRISPR-based diagnostics and microfluidics with a streamlined workflow for clinical use. We developed the mCARMEN respiratory virus panel to test for up to 21 viruses, including SARS-CoV-2, other coronaviruses and both influenza strains, and demonstrated its diagnostic-grade performance on 525 patient specimens in an academic setting and 166 specimens in a clinical setting. We further developed an mCARMEN panel to enable the identification of 6 SARS-CoV-2 variant lineages, including Delta and Omicron, and evaluated it on 2,088 patient specimens with near-perfect concordance to sequencing-based variant classification. Lastly, we implemented a combined Cas13 and Cas12 approach that enables quantitative measurement of SARS-CoV-2 and influenza A viral copies in samples. The mCARMEN platform enables high-throughput surveillance of multiple viruses and variants simultaneously, enabling rapid detection of SARS-CoV-2 variants.

Abstract

An outbreak of over 1,000 COVID-19 cases in Provincetown, Massachusetts (MA), in July 2021-the first large outbreak mostly in vaccinated individuals in the US-prompted a comprehensive public health response, motivating changes to national masking recommendations and raising questions about infection and transmission among vaccinated individuals. To address these questions, we combined viral genomic and epidemiological data from 467 individuals, including 40% of outbreak-associated cases. The Delta variant accounted for 99% of cases in this dataset; it was introduced from at least 40 sources, but 83% of cases derived from a single source, likely through transmission across multiple settings over a short time rather than a single event. Genomic and epidemiological data supported multiple transmissions of Delta from and between fully vaccinated individuals. However, despite its magnitude, the outbreak had limited onward impact in MA and the US overall, likely due to high vaccination rates and a robust public health response.

Abstract

The COVID-19 pandemic has had a significant impact on the mental health and wellbeing of the world's population, with particularly negative effects on vulnerable populations, including autistic people. Although some consensus regarding specific impact on aspects of wellbeing and mental health in autism is starting to emerge, it is unclear whether the pandemic has increased suicide risk. The goals of this study were to examine (a) potential associations between COVID-19 impact and depression, personal wellbeing, and suicide risk factors in Australian autistic adults and (b) age and gender effects. The COVID-19 Impact Scale (CIS), Personal Wellbeing Index, Patient Health Questionnaire, and the Suicide Behavior Questionnaire, Revised (SBQ-R), were administered to 111 autistic adults aged 20 to 71 years during the second wave of the COVID-19 pandemic in Australia. COVID-19 impact showed small associations with poorer personal wellbeing (r = ���0.224, p = 0.023, [���0.409, ���0.016]) and higher depressive symptoms (r = 0.268, p = 0.006, [0.056, 0.445]) and was not associated with the SBQ-R suicide risk score (r = 0.081, p = 0.418, [���0.118, 0.264). No significant effects were identified for age. Although model results were similar for women and men, the strength of the associations between personal wellbeing and depression (z = ���2.16, p = 0.015), and depression and SBQ-R suicide risk (z = 1.961, p = 0.025), were stronger in women than in men. Qualitative analysis of an open response question from the CIS suggested that the pandemic had both positive and negative impacts on participants. The COVID-19 pandemic has had a large impact on the mental health and wellbeing of the world's population, particularly vulnerable populations such as autistic people. It is not known if these impacts on mental health and wellbeing have increased suicide risk. Our findings suggest that the impact of the COVID-19 pandemic may be associated with poorer wellbeing and higher depression, but is not associated with suicide risk. Overall, autistic people reported both positive and negative impacts of the pandemic on their lives.

Abstract

The $\Lambda_c^+$ baryon mass is measured using $\Lambda_c^+\to\Lambda K^0_S K^+$ and $\Lambda_c^+\to\Sigma^0 K^0_S K^+$ decays reconstructed in 232 fb$^{-1}$ of data collected with the BaBar detector at the PEP-II asymmetric-energy $e^+e^-$ storage ring. The $\Lambda_c^+$ mass is measured to be $2286.46\pm0.14\mathrm{MeV}/c^2$. The dominant systematic uncertainties arise from the amount of material in the tracking volume and from the magnetic field strength., Comment: 14 pages, 8 postscript figures, submitted to Phys. Rev.

Abstract

The COVID-19 pandemic has had a significant impact on the mental health and wellbeing of the world's population, with particularly negative effects on vulnerable populations, including autistic people. Although some consensus regarding specific impact on aspects of wellbeing and mental health in autism is starting to emerge, it is unclear whether the pandemic has increased suicide risk. The goals of this study were to examine (a) potential associations between COVID-19 impact and depression, personal wellbeing, and suicide risk factors in Australian autistic adults and (b) age and gender effects. The COVID-19 Impact Scale (CIS), Personal Wellbeing Index, Patient Health Questionnaire, and the Suicide Behavior Questionnaire, Revised (SBQ-R), were administered to 111 autistic adults aged 20 to 71 years during the second wave of the COVID-19 pandemic in Australia. COVID-19 impact showed small associations with poorer personal wellbeing (r = -0.224, p = 0.023, [-0.409, -0.016]) and higher depressive symptoms (r = 0.268, p = 0.006, [0.056, 0.445]) and was not associated with the SBQ-R suicide risk score (r = 0.081, p = 0.418, [-0.118, 0.264). No significant effects were identified for age. Although model results were similar for women and men, the strength of the associations between personal wellbeing and depression (z = -2.16, p = 0.015), and depression and SBQ-R suicide risk (z = 1.961, p = 0.025), were stronger in women than in men. Qualitative analysis of an open response question from the CIS suggested that the pandemic had both positive and negative impacts on participants. The COVID-19 pandemic has had a large impact on the mental health and wellbeing of the world's population, particularly vulnerable populations such as autistic people. It is not known if these impacts on mental health and wellbeing have increased suicide risk. Our findings suggest that the impact of the COVID-19 pandemic may be associated with poorer wellbeing and higher depression, but is not a

Abstract

Hepatitis B virus (HBV) is a major human pathogen that causes liver diseases. The main HBV RNAs are unspliced transcripts that encode the key viral proteins. Recent studies have shown that some of the HBV spliced transcript isoforms are predictive of liver cancer, yet the roles of these spliced transcripts remain elusive. Furthermore, there are nine major HBV genotypes common in different regions of the world, these genotypes may express different spliced transcript isoforms. To systematically study the HBV splice variants, we transfected human hepatoma cells, Huh7, with four HBV genotypes (A2, B2, C2 and D3), followed by deep RNA-sequencing. We found that 13-28 % of HBV RNAs were splice variants, which were reproducibly detected across independent biological replicates. These comprised 6 novel and 10 previously identified splice variants. In particular, a novel, singly spliced transcript was detected in genotypes A2 and D3 at high levels. The biological relevance of these splice variants was supported by their identification in HBV-positive liver biopsy and serum samples, and in HBV-infected primary human hepatocytes. Interestingly the levels of HBV splice variants varied across the genotypes, but the spliced pregenomic RNA SP1 and SP9 were the two most abundant splice variants. Counterintuitively, these singly spliced SP1 and SP9 variants had a suboptimal 5' splice site, supporting the idea that splicing of HBV RNAs is tightly controlled by the viral post-transcriptional regulatory RNA element.

28. The Air Between Us

Author

Brown, CM and Brown, CM

Abstract

From the clear skies of Central Otago to the dense smog of Tehran, LungSong makes connections through our most intimate act, breathing. Using song, dance and live sampling to travel from one place to another, resisting ‘the forgetting of air’ (Irigaray 1999), breath activates shifts between dimensions. Recordings of the atmosphere’s compositional change become an immersive sonic texture, choreography takes place in the spaces between us: in-land and On Air. LungSong is a multi-sited performance event in development by the creative team Carol Brown (choreography), Russell Scoones (sound design) and Kasia Pol (performance design). Living in a world that is in a state of chaos and emergency, facing climate catastrophes and humanitarian crises, this performance research project acknowledges that as artists we do not exist in a vacuum, apart from these realities but are confronted with them daily. Our living relations through inter-disciplinary practices, anticipate a future that cannot be known in advance, but upon whose unfolding, our kinesthetic and sonic tuning towards response-ability depends. LungSong is a performance experiment towards an ethics of breathing. Transcultural, transcontextual and inter-species, it locates air as matter, inspired and exhaled in a world that is shared. Drawing on research into the exchanges of breaths between New Zealand Māori, Iranian and Argentinian dancers and musicians in Aotearoa New Zealand, informed by feminist, queer and indigenous philosophies and cut with samples from atmospheric research science taking place in NIWA @ Lauder, this performative presentation aims to open a dialogue on that most taken for granted element of performance practice, the air between us.

Abstract

© 2018 The Royal Society of Chemistry. We present a comprehensive investigation of the CO2adsorption properties of an isostructural series of metal-organic frameworks, M-BTT (M = Cr, Mn, Fe, Cu; BTT3-= 1,3,5-benzenetristetrazolate), which exhibit a high density of open metal sites capable of polarizing and binding guest molecules. Coupling gas adsorption measurements with in situ neutron and X-ray diffraction experiments provides molecular-level insight into the adsorption process and enables rationalization of the observed adsorption isotherms. In particular, structural data confirms that the high initial isosteric heats of CO2adsorption for the series are directly correlated with the presence of open metal sites and further reveals the positions and orientations of as many as three additional adsorption sites. Density functional theory calculations that include van der Waals dispersion corrections quantitatively support the observed structural features associated with the primary and secondary CO2binding sites, including CO2positions and orientations, as well as the experimentally determined isosteric heats of CO2adsorption.

Abstract

© 2017 American Chemical Society. Small-molecule binding in metal-organic frameworks (MOFs) can be accurately studied both experimentally and computationally, provided the proper tools are employed. Herein, we compare and contrast properties associated with guest binding by means of density functional theory (DFT) calculations using nine different functionals for the M2(dobdc) (dobdc4- = 2,5-dioxido,1,4-benzenedicarboxylate) series, where M = Mg, Mn, Fe, Co, Ni, Cu, and Zn. Additionally, we perform Quantum Monte Carlo (QMC) calculations for one system to determine if this method can be used to assess the performance of DFT. We also make comparisons with previously published experimental results for carbon dioxide and water and present new methane neutron powder diffraction (NPD) data for further comparison. All of the functionals are able to predict the experimental variation in the binding energy from one metal to the next; however, the interpretation of the performance of the functionals depends on which value is taken as the reference. On the one hand, if we compare against experimental values, we would conclude that the optB86b-vdW and optB88-vdW functionals systematically overestimate the binding strength, while the second generation of van der Waals (vdW) nonlocal functionals (vdw-DF2 and rev-vdW-DF2) correct for this providing a good description of binding energies. On the other hand, if the QMC calculation is taken as the reference then all of the nonlocal functionals yield results that fall just outside the error of the higher-level calculation. The empirically corrected vdW functionals are in reasonable agreement with experimental heat of adsorptions but under bind when compared with QMC, while Perdew-Burke-Ernzerhof fails by more than 20 kJ/mol regardless of which reference is employed. All of the functionals, with the exception of vdW-DF2, predict reasonable framework and guest binding geometries when compared with NPD measurements. The newest of the functionals considered, rev-vdW-DF2, should be used in place of vdW-DF2, as it yields improved bond distances with similar quality binding energies.

Abstract

The magnetic ground state of the quasi-one-dimensional spin-1 antiferromagnetic chain is sensitive to the relative sizes of the single-ion anisotropy (D) and the intrachain (J) and interchain (J′) exchange interactions. The ratios D/J and J′/J dictate the material's placement in one of three competing phases: a Haldane gapped phase, a quantum paramagnet, and an XY-ordered state, with a quantum critical point at their junction. We have identified [Ni(HF2)(pyz)2]SbF6, where pyz = pyrazine, as a rare candidate in which this behavior can be explored in detail. Combining neutron scattering (elastic and inelastic) in applied magnetic fields of up to 10 tesla and magnetization measurements in fields of up to 60 tesla with numerical modeling of experimental observables, we are able to obtain accurate values of all of the parameters of the Hamiltonian [D=13.3(1) K, J=10.4(3) K, and J′=1.4(2) K] , despite the polycrystalline nature of the sample. Density-functional theory calculations result in similar couplings (J=9.2 K, J′=1.8 K) and predict that the majority of the total spin population resides on the Ni(II) ion, while the remaining spin density is delocalized over both ligand types. The general procedures outlined in this paper permit phase boundaries and quantum-critical points to be explored in anisotropic systems for which single crystals are as yet unavailable.

Abstract

OBJECTIVES: Few interventions have been designed that provide standardised information to primary care clinicians about the diagnostic and treatment recommendations resulting from cancer multidisciplinary team (MDT) (tumour board) meetings. This study aimed to develop, implement and evaluate a standardised template for lung cancer MDTs to provide clinical information and treatment recommendations to general practitioners (GPs). Specific objectives were to (1) evaluate template feasibility (acceptability, appropriateness and timeliness) with GPs and (2) document processes of preimplementation, implementation and evaluation within the MDT setting. DESIGN: A mixed-method study design using structured interviews with GPs and qualitative documentation of project logs about implementation processes. SETTING: Two hospitals in Central Sydney, New South Wales, Australia. PARTICIPANTS: 61 GPs evaluated the template. Two lung cancer MDTs, consisting of 33 clinicians, and eight researchers participated in template development and implementation strategy. RESULTS: The MDT-reporting template appears to be a feasible way of providing clinical information to GPs following patient presentation at a lung cancer MDT meeting. Ninety-five per cent of GPs strongly agreed or agreed that the standardised template provided useful and relevant information, that it was received in a timely manner (90%) and that the information was easy to interpret and communicate to the patient (84%). Implementation process data show that the investment made in the preimplementation stage to integrate the template into standard work practices was a critical factor in successful implementation. CONCLUSIONS: This study demonstrates that it is feasible to provide lung cancer MDT treatment recommendations to GPs through implementation of a standardised template. A simple intervention, such as a standardised template, can help to address quality gaps and ensure that timely information is communicated between tert

© 2015 American Chemical Society. A thorough experimental and computational study has been carried out to elucidate the mechanistic reasons for the high volumetric uptake of methane in the metal-organic framework Cu3(btc)2 (btc3- = 1,3,5-benzenetricarboxylate; HKUST-1). Methane adsorption data measured at several temperatures for Cu3(btc)2, and its isostructural analogue Cr3(btc)2, show that there is little difference in volumetric adsorption capacity when the metal center is changed. In situ neutron powder diffraction data obtained for both materials were used to locate four CD4 adsorption sites that fill sequentially. This data unequivocally shows that primary adsorption sites around, and within, the small octahedral cage in the structure are favored over the exposed Cu2+ or Cr2+ cations. These results are supported by an exhaustive parallel computational study, and contradict results recently reported using a time-resolved diffraction structure envelope (TRDSE) method. Moreover, the computational study reveals that strong methane binding at the open metal sites is largely due to methane-methane interactions with adjacent molecules adsorbed at the primary sites instead of an electronic interaction with the metal center. Simulated methane adsorption isotherms for Cu3(btc)2 are shown to exhibit excellent agreement with experimental isotherms, allowing for additional simulations that show that modifications to the metal center, ligand, or even tuning the overall binding enthalpy would not improve the working capacity for methane storage over that measured for Cu3(btc)2 itself.

Abstract

The well-known frameworks of the type M2(dobdc) (dobdc 4- = 2,5-dioxido-1,4-benzenedicarboxylate) have numerous potential applications in gas storage and separations, owing to their exceptionally high concentration of coordinatively unsaturated metal surface sites, which can interact strongly with small gas molecules such as H2. Employing a related meta-functionalized linker that is readily obtained from resorcinol, we now report a family of structural isomers of this framework, M 2(m-dobdc) (M = Mg, Mn, Fe, Co, Ni; m-dobdc4- = 4,6-dioxido-1,3-benzenedicarboxylate), featuring exposed M2+ cation sites with a higher apparent charge density. The regioisomeric linker alters the symmetry of the ligand field at the metal sites, leading to increases of 0.4-1.5 kJ/mol in the H2 binding enthalpies relative to M 2(dobdc). A variety of techniques, including powder X-ray and neutron diffraction, inelastic neutron scattering, infrared spectroscopy, and first-principles electronic structure calculations, are applied in elucidating how these subtle structural and electronic differences give rise to such increases. Importantly, similar enhancements can be anticipated for the gas storage and separation properties of this new family of robust and potentially inexpensive metal-organic frameworks. © 2014 American Chemical Society.

Abstract

Using a data sample corresponding to an integrated luminosity of 342 fb(-1) collected with the BABAR detector at the SLAC PEP-II electron-positron storage ring operating at a center-of-mass energy near 10.58 GeV, we measure B(tau(-)->pi(-)pi(-)pi(+)nu(tau)(ex.K(S)(0)))=(8.83 +/- 0.01 +/- 0.13)%, B(tau(-)-> K(-)pi(-)pi(+)nu(tau)(ex.K(S)(0)))=(0.273 +/- 0.002 +/- 0.009)%, B(tau(-)-> K(-)pi(-)K(+)nu(tau))=(0.1346 +/- 0.0010 +/- 0.0036)%, and B(tau(-)-> K(-)K(-)K(+)nu(tau))=(1.58 +/- 0.13 +/- 0.12)x10(-5), where the uncertainties are statistical and systematic, respectively. These include significant improvements over previous measurements and a first measurement of B(tau(-)-> K(-)K(-)K(+)nu(tau)) in which no resonance structure is assumed. We also report a first measurement of B(tau(-)->phi pi(-)nu(tau))=(3.42 +/- 0.55 +/- 0.25)x10(-5), a new measurement of B(tau(-)->phi K(-)nu(tau))=(3.39 +/- 0.20 +/- 0.28)x10(-5) and a first upper limit on B(tau(-)-> K(-)K(-)K(+)nu(tau)(ex.phi)).

Abstract

We measure the branching ratios of the Cabibbo-suppressed decays Lambda(+)(c)->Lambda K+ and Lambda(+)(c)->Sigma K-0(+) relative to the Cabibbo-favored decay modes Lambda(+)(c)->Lambda pi(+) and Lambda(+)(c)->Sigma(0)pi(+) to be 0.044 +/- 0.004 (stat.)+/- 0.003 (syst.) and 0.038 +/- 0.005 (stat.)+/- 0.003 (syst.), respectively. We set an upper limit on the branching ratio at the 90% confidence level for Lambda(+)(c)->Lambda K+pi(+)pi(-) of 4.1x10(-2) relative to Lambda(+)(c)->Lambda pi(+), and for Lambda(+)(c)->Sigma K-0(+)pi(+)pi(-) of 2.0x10(-2) relative to Lambda(+)(c)->Sigma(0)pi(+). We also measure the branching fraction for the Cabibbo-favored mode Lambda(+)(c)->Sigma(0)pi(+) relative to Lambda(+)(c)->Lambda pi(+) to be 0.977 +/- 0.015 (stat.)+/- 0.051 (syst.). This analysis was performed using a data sample with an integrated luminosity of 125 fb(-1) collected by the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC.

Abstract

We present improved measurements of the branching fraction and CP asymmetry for the process B-+/-->rho(+/-)pi(0). The data sample corresponding to 211 fb(-1) comprises 232x10(6) Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. The yield and CP asymmetry are measured using an extended maximum likelihood fitting method. The branching fraction and CP asymmetry are found to be B(B-+/-->rho(+/-)pi(0))=[10.2 +/- 1.4(stat)+/- 0.9(syst)]x10(-6) and A(CP)(B-+/-->rho(+/-)pi(0))=-0.01 +/- 0.13(stat)+/- 0.02(syst).

The data sample corresponds to 232 x 10(6) BB pairs collected with the BABAR detector at the PEP-II asymmetric-energy B factory at the Stanford Linear Accelerator Center. We measure the branching fractions (in units of 10(-6)) B(B-0 -> eta'K-*0) = 3.8 +/- 1.1 +/- 0.5 and B(B+ -> eta'K*+) = 4.9(-1.7)(+1.9) +/- 0.8, where the first error is statistical and the second systematic. A simultaneous fit results in the observation of B -> eta'K-* with B(B -> eta'K-*) = 4.1(-0.9)(+1.0) +/- 0.5. We also search for B -> eta'rho and eta'f(0)(980)(f(0) -> pi(+) pi(-)) with results and 90% confidence level upper limits B(B+ -> eta'rho(+)) = 8.7(-2.8-1.3)(+3.1+2.3) (< 14), B(B0 -> eta'rho(0)) < 3.7, and B(B-0 -> eta'f(0)(980)(f(0) -> pi(+) pi(-))) < 1.5. Charge asymmetries in the channels with significant yields are consistent with zero.

Abstract

We report on a search for the lepton- flavor- violating processes e(+) e(-) -> mu(+) tau(-) and e(+) e(-) -> e(+) tau(-). The data sample corresponds to an integrated luminosity of 211 fb(-1) recorded by the BABAR experiment at the SLAC PEP-II asymmetric-energy B Factory at a center-of-mass energy of root s = 10.58 GeV. We find no evidence for a signal and set the 90% confidence level upper limits on the cross sections to be sigma (mu tau) < 3.8 fb and sigma(e tau) < 9.2 fb. The ratio of the cross sections with respect to the dimuon cross section are measured to be sigma (mu tau)/sigma (mu mu) < 3.4 X 10(-6) and sigma (e tau)/sigma (mu mu) < 8.2 X 10(-6).

Abstract

We present measurements of the branching fractions for the charmless two-body decays B-0 ->pi(+)pi(-) and B-0 -> K+pi(-), and a search for the decay B-0 -> K+K-. We include the effects of final-state radiation from the daughter mesons for the first time, and quote branching fractions for the inclusive processes B-0 -> h(+)h('-)n gamma, where h and h(') are pions or kaons. The maximum value of the sum of the energies of the n undetected photons, E-gamma(max), is mode-dependent. Using a data sample of approximately 227x10(6) Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) collider at SLAC, we measure: B(B-0 ->pi(+)pi(-)n gamma;E-gamma(max)=150 MeV)=(5.1 +/- 0.4 +/- 0.2)x10(-6), B(B-0 -> K+pi(-)n gamma;E-gamma(max)=105 MeV)=(18.1 +/- 0.6 +/- 0.6)x10(-6), B(B-0 -> K(+)K(-)n gamma;E-gamma(max)=59 MeV)< 0.5x10(-6)(90% confidence level), where the first uncertainty is statistical and the second is systematic. Theoretical calculations can be used to extrapolate from the above measurements the nonradiative branching fractions, B-0. Using one such calculation, we find: B-0(B-0 ->pi(+)pi(-))=(5.5 +/- 0.4 +/- 0.3)x10(-6), B-0(B-0 -> K+pi(-))=(19.1 +/- 0.6 +/- 0.6)x10(-6), B-0(B-0 -> K+K-)< 0.5x10(-6)(90% confidence level). Meaningful comparison between theory and experiment, as well as combination of measurements from different experiments, can be performed only in terms of these nonradiative quantities.

Abstract

A search for charmed baryons decaying to D(0)p reveals two states: the Lambda(c)(2880)(+) baryon and a previously unobserved state at a mass of [2939.8 +/- 1.3(stat)+/- 1.0(syst)] MeV/c(2) and with an intrinsic width of [17.5 +/- 5.2(stat)+/- 5.9(syst)] MeV. Consistent and significant signals are observed for the K-pi(+) and K-pi(+)pi(-)pi(+) decay modes of the D-0 in 287 fb(-1) annihilation data recorded by the BABAR detector at a center-of-mass energy of 10.58 GeV. There is no evidence in the D(+)p spectrum of doubly charged partners. The mass and intrinsic width of the Lambda(c)(2880)(+) baryon and relative yield of the two baryons are also measured.

Abstract

Using 65 X 10(6) Y (4S) -> BB events collected with the BABAR detector at the PEP-II e(+) e(-) storage ring at the Stanford Linear Accelerator Center, we measure the color-favored branching fractions B(B-0 -> D+ pi(-)) = (2.55 +/- 0.05 +/- 0.16) X 10(-3), B(B-0 -> D*(+) pi(-)) = (2.79 +/- 0.08 +/- 0.17) X 10(-3), B(B- -> D-0 pi(-)) = (4.90 +/- 0.07 +/- 0.22) X 10(-3) and B(B- -> D*(0)pi(-)) = (5.52 +/- 0.17 +/- 0.42) X 10(-3), where the first error is statistical and the second is systematic. With these results and the current world average for the branching fraction for the color-suppressed decay B-0 -> D-(*()0)pi(0), the cosines of the strong phase difference delta between the I =1/2 and I = 3/2 isospin amplitudes are determined to be cos delta = 0.872(-0.007 - 0.029)(+0.008+0.031) for the B -> D pi process and cos delta = 0.924(-0.017 - 0.054)(+ 0.019 + 0.063) for the B -> D*pi process. Under the isospin symmetry, the results for cos delta suggest the presence of final-state interactions in the D pi system.
