description: A study of the total cross section for polarized proton knockout in $(e,e'{\vec p})$ reactions is carried out for the closed-shell nucleus $^{40}$Ca. The dependence of FSI effects on polarization observables viewed as functions of the nucleon polarization angles is analyzed and interpreted within the basis of a semi-classical model for the orbit of the struck nucleon and trajectory of the ejected nucleon. A comparison with the case of a $^{39}$K polarized target and unpolarized protons is performed.

description: This article presents a sociotechnical framework for KM. This sociotechnical vision of KM allows: (1) to remove KM from a commercial concern; (2) to divide the different KM technologies; and (3) to question the paradigms associated with the social and technical components of KM. It is precisely this last point that this article develops to identify the generic mechanisms of KM. More precisely, the social aspect is explained through the organizational approach to KM, the managerial approach to KM, and the biological approach to KM. In contrast, the technical aspect is described through the knowledge and skills engineering approach to KM. These approaches also lead us to provide a comparative table between these organizational, managerial, and biological visions of KM.

description: This research focuses on the use of concrete demolition wastes to produce High Performance Concrete. The energy discharge during cement production can pose a health risk, and the continuous quarrying of natural aggregates for concrete production from river beds, seashores, and other sources, if not done in accordance with environmental guidelines, can completely devastate our planet. Therefore, scientists, researchers and other related professionals are trying to improve recycled materials to be used as aggregates. Recycled aggregates concrete, with certain adjustments, is one solution for this need. This study aims to evaluate the Experimental investigation of the use of demolition wastes from urbanite concrete samples at Adenuga Building, Bells University of Technology, Ota, Ogun State, Nigeria in the production of high-performance concrete. There were 20 series of mix designs. Recycled coarse aggregate percentage replacements of Natural coarse aggregate was adopted from 0% to 100% at 25% interval, the fiber contents replacements of the concrete volume were integrated at 0% to 1.5 % at 0.5% interval, and the NBRRI Pozzolan (NP) replacements of the cement volume was substituted at 0% to 15% at 5% interval. Various fresh and hardened properties of concrete such as Slump test, Compressive, splitting tensile and Flexural strength tests were determined and tests on cement, aggregates, such as Specific gravity, Sieve analysis were also carried out in accordance with BS standards. It was observed from the results that optimum value of 50.69 MPa, 6.14 MPa, and 2.18MPa were obtained for compressive, flexural and splitting tensile strengths of the concrete at 25% RAC addition, 5% addition of NBRRI pozzolan with 0.5% glass fiber content at 28 days curing age respectively. It is concluded that addition of glass fibre to concrete made by replacing cement with NBRRI pozzolan significantly improved the strength of the concrete. High performance concrete using recycled materials can be adopted in the construction of high-rise structures, bridges, pavements, hydropower structures, tunnels, and other current and future construction projects.

description: High-redshift blazars are among the most powerful objects in the Universe. The spectral and temporal properties of thirty-three distant blazars ($z>2.5$) detected in the high energy $γ$-ray band are investigated by analyzing the {\it Fermi}-LAT and {\it Swift} UVOT/ XRT data. The considered sources have soft time averaged $γ$-ray spectra ($Γ_{\rm γ}\geq2.2$) whereas those that have been observed in the X-ray band have hard X-ray spectra ($Γ_{\rm X}=1.01-1.86$). The $γ$-ray flux of high-redshift blazars ranges from $4.84\times10^{-10}$ to $1.50\times10^{-7}\:{\rm photon\:cm^{-2}\:s^{-1}}$ and the luminosity is within $(0.10-5.54)\times10^{48}\:{\rm erg\:s^{-1}}$ which during the $γ$-ray flares increases up to $(0.1-1)\times10^{50}\:{\rm erg\:s^{-1}}$. In the X-ray band, only the emission of PKS 0438-43, B2 0743+25 and TXS 0222+185 is found to vary in different Swift XRT observations whereas in the $γ$-ray band, the emission is variable for fourteen sources: the flux of B3 1343+451 and PKS 0537-286 changes in sub-day scales, that of PKS 0347-211 and PKS 0451-28 in day scales, while the$γ$-ray variability of the others is in week or month scales. The properties of distant blazar jets are derived by modeling the multiwavelength spectral energy distributions within a one-zone leptonic scenario assuming that the X-ray and $γ$-ray emissions are produced from inverse Compton scattering of synchrotron and dusty torus photons. From the fitting, the emission region size is found to be $\leq0.05$ pc and the magnetic field and the Doppler factor are correspondingly within $0.10-1.74$ G and $10.0-27.4$. By modeling the optical-UV excess, we found that the central black hole masses and accretion disk luminosities are within $L_{\rm d}\simeq(1.09-10.94)\times10^{46}\:{\rm erg \: s^{-1}}$ and $(1.69-5.35)\times10^{9}\:M_\odot$, respectively.

description: The achievement of three-dimensional atomic resolution magnetic resonance microscopy remains one of the main challenges in the visualization of biological molecules. The prospects for single spin microscopy have come tantalizingly close due to the recent developments in sensitive instrumentation. Despite the single spin detection capability in systems of spatially well-isolated spins, the challenge that remains is the creation of conditions in space where only a single spin is resonant and detected in the presence of other spins in its natural dense spin environment. We present a nanomagnetic planar design where a localized Angstrom-scale point in three-dimensional space is created above the nanostructure with a non-zero minimum of the magnetic field magnitude. The design thereby represents a magnetic resonance microscopy lens where potentially only a single spin located in the focus spot of the structure is resonant. Despite the presence of other spins in the Angstrom-scale vicinity of the resonant spin, the high gradient magnetic field of the lens renders those spins inactive in the detection process.

description: In this work we introduce PowerModelsDistribution, a free, open-source toolkit for distribution power network optimization, whose primary focus is establishing a baseline implementation of steady-state multi-conductor unbalanced distribution network optimization problems, which includes implementations of Power Flow and Optimal Power Flow problem types. Currently implemented power flow formulations for these problem types include AC (polar and rectangular), a second-order conic relaxation of the Branch Flow Model (BFM) and Bus Injection Model (BIM), a semi-definite relaxation of BFM, and several linear approximations, such as the simplified unbalanced BFM. The results of AC power flow have been validated against OpenDSS, an open-source "electric power distribution system simulator", using IEEE distribution test feeders (13, 34, 123 bus and LVTestCase), all parsed using a built-in OpenDSS parser. This includes support for standard distribution system components as well as novel resource models such as generic energy storage (multi-period) and photovoltaic systems, with the intention to add support for additional components in the future.

description: We consider black-string-type solutions in five-dimensional Einstein-Gauss-Bonnet gravity. Numerically constructed solutions under static, axially symmetric and translationally invariant metric ansatz are presented. The solutions are specified by two asymptotic charges: mass of a black string and a scalar charge associated with the radion part of the metric. Regular black string solutions are found if and only if the two charges satisfy a fine-tuned relation, and otherwise the spacetime develops a singular event horizon or a naked singularity. We can also generate bubble solutions from the black strings by using a double Wick rotation.

This paper verifies how the producer, in special the horticultural farmer in urban areas, behave face to environmental and social questions regarding chemical package dealing, for instance. It was interviewed 21 horticultural producers in the city of Piracicaba, São Paulo State. The results indicate that half of the interviewed are characterized as conscience beginners and no one as conscientious, justifying new campaigns of education turned to producers in order to raise their environmental e social practices.

Abstract
Rosuvastatin/ezetimibe combines two lipid-lowering agents: rosuvastatin, an HMG-CoA reductase inhibitor (i.e. statin) with particularly strong inhibitory effects on hepatic cholesterol synthesis, and ezetimibe, which inhibits the intestinal absorption of cholesterol. A fixed-dose combination (FDC) of rosuvastatin/ezetimibe is indicated as an adjunctive therapy to diet for the management of primary hypercholesterolemia in adults in numerous countries worldwide. In well-designed clinical trials evaluating the therapeutic efficacy of rosuvastatin/ezetimibe administered as either separate agents or as an FDC, rosuvastatin/ezetimibe was significantly more effective than rosuvastatin monotherapy (including at double the dose of rosuvastatin) or simvastatin/ezetimibe in reducing low-density lipoprotein cholesterol (LDL-C) and total cholesterol in adults with hypercholesterolemia. Furthermore, rosuvastatin/ezetimibe enabled significantly higher proportions of patients to achieve recommended LDL-C levels than rosuvastatin monotherapy or simvastatin/ezetimibe. Rosuvastatin/ezetimibe did not significantly differ from rosuvastatin monotherapy with respect to incidences of treatment-related or serious adverse events in these short-term trials and displayed a similar safety profile to simvastatin/ezetimibe. While additional cardiovascular outcomes data and head-to-head comparisons with atorvastatin/ezetimibe would be of interest, rosuvastatin/ezetimibe is a potent and generally well-tolerated drug combination that extends the range of options available for the pharmacological management of primary hypercholesterolemia in adults.

Dissipative Photosphere Models of Gamma-ray Bursts and X-ray Flashes

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: We consider dissipative effects occurring in the optically thick inner parts of the relativistic outflows producing gamma-ray bursts and X-ray flashes, emphasizing specially the Comptonization of the thermal radiation flux that is advected from the base of the outflow. Such dissipative effects --e.g. from magnetic reconnection, neutron decay or shocks -- would boost the energy density of the thermal radiation. The dissipation can lead to pair production, in which case the pairs create an effective photosphere further out than the usual baryonic one. In a slow dissipation scenario, pair creation can be suppressed, and the effects are most important when dissipation occurs below the baryonic photosphere. In both cases an increased photospheric luminosity is obtained. We suggest that the spectral peak in gamma ray bursts is essentially due to the Comptonized thermal component from the photosphere, where the comoving optical depth in the outflow falls to unity. Typical peak photon energies range between those of classical bursts and X-ray flashes. The relationship between the observed photon peak energy and the luminosity depends on the details of the dissipation, but under plausible assumptions can resemble the observed correlations.

"This is not a whorehouse!" : sexual activity in long-term care
Creators: name: Everett, Bethan Joan
Publisher: name: University of British Columbia
Year: 2010

description: A society's moral heart can be judged by how well it provides for its weakest and most vulnerable citizens. In recent years significant strides have been made to improve the quality of institutionalized persons' lives. However, because we have not yet fully developed a moral vision of long-term care living, residents do not always receive the basic care that they should. Particularly ignored and inadequately addressed is the complex moral and social issue of residents' sexual lives. Currently there is little support for sexual activity or sexual care in long-term care settings. Society's moral rules are designed for independent people living in their own homes. Professional governance bodies have created moral rules regulating short-term professional interactions and responsibilities but rarely have ones that pertain to longterm care settings. The aim of the present research is to contribute to the development of a moral vision of how long-term care institutions should manage sexual activity and sexual care. A qualitative study was designed to identify the factors that negatively influence sexual activity and sexual care, and the supports that residents and staff respectively need in order to have sexual lives and provide sexual care. Using an exploratory design the investigator conducted in-depth interviews with twenty-four residents and staff and carried out twenty hours of participant observation with two community residents. Six negative influences on residents' sexual lives and nine negative influences on staffs provision of sexual care were identified. The work also explores ethical and legal issues pertaining to the provision o f sexual care. It is argued that residents have moral rights to sexual care which impose duties on institutions to provide that care. Legal barriers to providing such care are then considered, and found not to be insurmountable. The above research and explorations led to three conclusions. First, unless sexual care is available residents cannot have sexual lives. Second, for sexual care to be available institutions must accept that it is their moral responsibility to provide it and ensure that staff are adequately supported. Third, institutions should develop a framework for the delivery of sexual care.

description: The NLP community has broadly focused on text-only approaches of cognitive state tasks, but audio can provide vital missing cues through prosody. We posit that text-to-speech models learn to track aspects of cognitive state in order to produce naturalistic audio, and that the signal audio models implicitly identify is orthogonal to the information that language models exploit. We present Synthetic Audio Data fine-tuning (SAD), a framework where we show that 7 tasks related to cognitive state modeling benefit from multimodal training on both text and zero-shot synthetic audio data from an off-the-shelf TTS system. We show an improvement over the text-only modality when adding synthetic audio data to text-only corpora. Furthermore, on tasks and corpora that do contain gold audio, we show our SAD framework achieves competitive performance with text and synthetic audio compared to text and gold audio.

description: We discuss a photon collider based on the $e^+e^-$ \ linear collider with energies of $2E = 1÷2$ TeV in cms (ILC, CLIC, ...). Previously, this energy range was considered hopeless for the experiment in the foreseeable future. We discuss the realization of the TeV PLC based on modern lasers. A small modification of the laser-optical system prepared for the photon collider with energy of $E \approx 250$ GeV will be sufficient if the parameters are chosen optimally. The high-energy part of the photon spectrum does not depend on design details and is well separated from the low-energy part. That is a narrow band near the upper boundary, about 5\% wide. The high-energy integrated \ggam luminosity is about 1/5 and the maximum differential luminosity is about 1/4 of the corresponding values for the photon collider with $E \approx 250$ GeV.

description: The current-voltage characteristic of a one dimensional quantum dot connected via tunnel barriers to interacting leads is calculated in the region of sequential tunneling. The spin of the electrons is taken into account. Non-Fermi liquid correlations implying spin-charge separation are assumed to be present in the dot and in the leads. It is found that the energetic distance of the peaks in the linear conductance shows a spin-induced parity effect at zero temperature T. The temperature dependence of the positions of the peaks depends on the non-Fermi liquid nature of the system. For non-symmetric tunnel barriers negative differential conductances are predicted, which are related to the participation in the transport of collective states in the quantum dot with larger spins. Without spin-charge separation the negative differential conductances do not occur. Taking into account spin relaxation destroys the spin-induced conductance features. The possibility of observing in experiment the predicted effects are briefly discussed.

description: Probabilistic programming is perfectly suited to reliable and transparent data science, as it allows the user to specify their models in a high-level language without worrying about the complexities of how to fit the models. Static analysis of probabilistic programs presents even further opportunities for enabling a high-level style of programming, by automating time-consuming and error-prone tasks. We apply static analysis to probabilistic programs to automate large parts of two crucial model checking methods: Prior Predictive Checks and Simulation-Based Calibration. Our method transforms a probabilistic program specifying a density function into an efficient forward-sampling form. To achieve this transformation, we extract a factor graph from a probabilistic program using static analysis, generate a set of proposal directed acyclic graphs using a SAT solver, select a graph which will produce provably correct sampling code, then generate one or more sampling programs. We allow minimal user interaction to broaden the scope of application beyond what is possible with static analysis alone. We present an implementation targeting the popular Stan probabilistic programming language, automating large parts of a robust Bayesian workflow for a wide community of probabilistic programming users.

description: The entry of Ukraine into the European Union significantly expands the boundaries of cooperation with different countries of the world. Compliance with the European requirements in the marketing sector will greatly increase the efficiency of its operation in the regions of Ukraine. The method of estimating the development of social infrastructure in the resource support of the management mechanism aimed at increasing the competitiveness of the transport system of the region by the integral indicator, which characterizes the level of social development of the region, is developed in the work. The integral indicator is defined as the sum of the ratios of the current and maximum partial indicators of population security by type of services in the region. The components of the process of social development assessment have been introduced: a limitation on the magnitude of each type of resource used to improve social development indicators; specific expenses of each type of resource in the region in support and improvement of the indicator of social development; the magnitude of the growth of the provision of the region for each indicator of social development; the function of the priorities of social development in the region for each indicator. It is believed that using the results of calculations using the proposed method will increase the validity of relevant management decisions.

description: O grande desafio do arranjo vitivinícola da Serra Gaúcha é o aumento da competitividade dos vinhos finos nacionais. Isso poderá ocorrer por medidas de reduções tributárias, pelo aumento do consumo per capita brasileiro de vinho e, principalmente pela implementação de inovações e de estratégias que promovam a melhoria da qualidade dos vinhos e por meio de medidas jurídicas que atestem essa qualidade como as indicações geográficas. Constata-se que na região do Vale dos Vinhedos, na Serra Gaúcha/RS/Brasil, as vinícolas estão implementando inovações e estratégias de competição e cooperação com vistas à obtenção anual da indicação de procedência para os vinhos finos. Nesse contexto, este artigo tem como objetivo identificar as inovações e as estratégias que têm sido desenvolvidas por uma vinícola do arranjo vitivinícola gaúcho para a obtenção da Indicação de Procedência Vale dos Vinhedos - IPVV. O método da pesquisa é o estudo de caso aplicado a Vinícola Boutique Lídio Carraro, localizada no Vale dos Vinhedos, na Serra Gaúcha-RS/Brasil. Os dados foram coletados através de entrevistas realizadas como os gestores e enólogo.

description: We present cosmological constraints on deviations of Newton's constant at large scales, analyzing latest cosmic microwave background (CMB) anisotropies and primordial abundances of light elements synthesized by big bang nucleosynthesis (BBN). BBN limits the possible deviation at typical scales of BBN epoch, say at 10^8 \sim 10^12m, to lie between -5% and +1% of the experimental value, and CMB restricts the deviation at larger scales 10^2 \sim 10^9pc to be between -26% and +66% at the 2σconfidence level. The cosmological constraints are compared with the astronomical one from the evolution of isochrone of globular clusters.

description: The space of Lamé functions of order m is isomorphic to the space of pairs (elliptic curve, Abelian differential) where the differential has a single zero of order 2m at the origin and m double poles with vanishing residues. We describe the topology of this space: it is a Riemann surface of finite type; we find the number of components and the genus and Euler characteristic of each component. As an application we find the degrees of Cohn's polynomials confirming a conjecture by Robert Maier. As another application we partially describe the degeneration locus of the space of spherical metrics on tori with one conic singularity where the conic angle is an odd multiple of 2$π$.

description: The behaviour of ferromagnetic systems with single-ion anisotropies in more than one direction is investigated with many-body Green's function theory generalizing earlier work with uniaxial anisotropies only. It turns out to be of advantage to construct Green's functions in terms of the spin operators S^x, S^y and S^z, instead of the commonly used S^+,S^- and S^z operators. The exchange energy terms are decoupled by RPA and the single-ion anisotropy terms by a generalization of the Anderson-Callen decoupling. We stress that in the derivation of the formalism none of the three spatial axes is special, so that one is always able to select a reference direction along which a magnetization component is not zero. Analytical expressions are obtained for all three components of the magnetization and the expectation values , and for any spin quantum number S. The formalism considers both in-plane and out-of-plane anisotropies. Numerical calculations illustrate the behaviour of the magnetization for 3-dimensional and 2-dimensional systems for various parameters. In the 2-dimensional case, the magnetic dipole-dipole coupling is included, and a comparison is made between in-plane and out-of-plane anisotropies.

A study of health care professionals’ experiences of witnessed suffering
Creators: name: Sork, Jamie
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of the study was to investigate the day to day experiences of health care professionals who witness suffering in their work. The existing literature largely focuses on the negative consequences of experiencing difficult life situations involving suffering. There is less existing literature that focuses on the experiences other than vicarious trauma. Acknowledging the quantity of the existing research, the methodology chosen for this research that best addresses these issues was an exploratory phenomenological methodology. The general conclusions of this study highlight key aspects of the participants' experiences of witnessing suffering. This study identified four major themes which are; the impact of witnessing suffering, meaning making and the connection with something larger, holding a sense of duality and finally the participants' evolution over time. The first theme is the impact of witnessing suffering, which describes what these participants experienced as the look back over the many experiences of witnessing suffering. The next theme focuses on the meaning made by each participant as they witnessed suffering which includes their personal connection with something larger. This discovery highlights the pivotal role the participants' personal spiritual perspective plays throughout their work. The next theme describes the participants' experience of holding a sense of duality or holding opposing forces simultaneously as they encountered the day to day experiences of witnessing suffering. They noted how essential the holding a sense of duality is for continued engagement in their work. The final theme describes these participants evolution over time in relation to the frequent experiences of witnessing suffering day to day in their work. The changes noted include change/growth in their sense of self, physical responses, emotions, expectations, and their spiritual development. It is clear that further research is indicated to further define the factors involved and seek a greater understanding of the paradox of witnessing suffering and experiencing growth. The importance of this greater understanding has numerous implications for professional training and could also assist in reducing professional burnout and increase opportunities for professional growth and development in the future.

Ultramafic-mafic cumulate rocks often situated at deep root zones of the magmatic systems when they intruded into continental crustal areas. In rare occurrences, they can also intrude at the middle to upper portion of the crust and record the MASH processes developed within the crust. Yıldızdağ Gabbroic Intrusion (YGI) represents one of the rare occurrences of the middle Eocene post-collisional magmatism in Turkey that record the storage of a shallow seated cumulate mush.
Primordial Black Holes, Hawking Radiation and the Early Universe

description: The 511 keV gamma emission from the galactic core may originate from a high concentration ($\sim 10^{22}$) of primordial black holes (PBHs) in the core each of whose Hawking radiation includes $\sim 10^{21}$ positrons per second. The PBHs we consider are taken as near the lightest with longevity greater than the age of the universe (mass $\sim 10^{12}$ kg; Schwarzschild radius $\sim 1$ fm). These PBHs contribute only a small fraction of cold dark matter, $Ω_{PBH} \sim 10^{-8}$. This speculative hypothesis, if confirmed implies the simultaneous discovery of Hawking radiation and an early universe phase transition.

Gauge Transformations and Inverse Quantum Scattering with Medium-Range Magnetic Fields

description: The time-dependent, geometric method for high-energy limits and inverse scattering is applied to nonrelativistic quantum particles in external electromagnetic fields. Both the Schr"odinger- and the Pauli equations in R^2 and R^3 are considered. The electrostatic potential A_0 shall be short-range, and the magnetic field B shall decay faster than |x|^{-3/2} . A natural class of corresponding vector potentials A of medium range is introduced, and the decay and regularity properties of various gauges are discussed, including the transversal gauge, the Coulomb gauge, and the Griesinger vector potentials. By a suitable combination of these gauges, B need not be differentiable. The scattering operator S is not invariant under the corresponding gauge transformations, but experiences an explicit transformation. Both B and A_0 are reconstructed from an X-ray transform, which is obtained from the high-energy limit of S . Here previous results by Arians and Nicoleau are generalized to the medium-range situation. In a sequel paper, medium-range vector potentials are applied to relativistic scattering.

Memory-efficient structured convex optimization via extreme point sampling

description: Memory is a key computational bottleneck when solving large-scale convex optimization problems such as semidefinite programs (SDPs). In this paper, we focus on the regime in which storing an $n\times n$ matrix decision variable is prohibitive. To solve SDPs in this regime, we develop a randomized algorithm that returns a random vector whose covariance matrix is near-feasible and near-optimal for the SDP. We show how to develop such an algorithm by modifying the Frank-Wolfe algorithm to systematically replace the matrix iterates with random vectors. As an application of this approach, we show how to implement the Goemans-Williamson approximation algorithm for \textsc{MaxCut} using $\mathcal{O}(n)$ memory in addition to the memory required to store the problem instance. We then extend our approach to deal with a broader range of structured convex optimization problems, replacing decision variables with random extreme points of the feasible region.

description: Der Mensch versteht sich nicht mehr als Person, die wahrnimmt und erlebt, sondern rückt zusehends an diese Stelle sein zentrales Nervensystem, das Gehirn. In der Heftausgabe wird anhand von 34 Alltagsstationen exemplarisch ein Perspektivwechsel vorgeführt. Die Textauszüge beinhalten bemerkenswerte Beobachtungen und sind in der Regel der phänomenologischen Leitidee verpflichtet, so weit wie möglich unvoreingenommen, d.h. ohne Rücksicht auf theoretische Vorannahmen das Gegebene zu beschreiben. Sie sind als Gesprächs- und Erkundungsanlässe nutzbar. Im besten Falle verhelfen die dargestellten Entdeckungen eine größere Aufmerksamkeit für die erfahrbare Welt auszubilden. Thematisch wurden die Auszüge nach tageszeitlichen Angaben oder denkbaren tageszeitlichen Situationen aneinandergereiht. So finden sich Klassiker der phänomenologischen Bewegung zwischen weniger prominenten Autoren, Beobachtungen aus der jüngsten Vergangenheit zwischen Beschreibungen aus der Anfangszeit der Phänomenologie. Im letzten Teil «Phänomene vorstellen» wird dann eine nähere Erläuterung und Einordnung der verschiedenen deskriptiven Texttypen geleistet.

description: We have studied the inclusive photon spectra in Upsilon(2S) and Υ(3S) decays using a large statistics data sample obtained with the CLEO III detector. We present the most precise measurements of electric dipole (E1) photon transition rates and photon energies for Upsilon(2S)->gamma chi_bJ(1P) and Upsilon(3S)->gamma chi_bJ(2P) J=0,1,2. We measure the rate for a rare E1 transition Upsilon(3S)->gamma chi_b0(1P) for the first time. We also set upper limits on the rates for the hindered magnetic dipole (M1) transitions to the eta_b(1S) and eta_b(2S) states.
