description: The anomalies in rare $B$ decays endure. We present results of an updated global analysis that takes into account the latest experimental input -- in particular the recent results on $R_K$ and BR$(B_s \to μ^+μ^-)$ -- and that qualitatively improves the treatment of theory uncertainties. Fit results are presented for the Wilson coefficients of four-fermion contact interactions. We find that muon specific Wilson coefficients $C_9 \simeq -0.73$ or $C_9 = -C_{10} \simeq -0.39$ continue to give an excellent description of the data. If only theoretically clean observables are considered, muon specific $C_{10} \simeq 0.60$ or $C_9=-C_{10} \simeq -0.35$ improve over the Standard Model by $\sqrt{Δχ^2} \simeq 4.7σ$ and $\sqrt{Δχ^2} \simeq 4.6σ$, respectively. In various new physics scenarios we provide predictions for lepton flavor universality observables and CP asymmetries that can be tested with more data. We update our previous combination of ATLAS, CMS, and LHCb data on BR$(B_s \to μ^+μ^-)$ and BR$(B^0\to μ^+μ^-)$ taking into account the full two-dimensional non-Gaussian experimental likelihoods.

description: The effects of the symmetry energy softening of the relativistic mean field (RMF) models on the properties of matter with neutrino trapping are investigated. It is found that the effects are less significant than those in the case without neutrino trapping. The weak dependence of the equation of state on the symmetry energy is shown as the main reason of this finding. Using different RMF models the dynamical instabilities of uniform matters, with and without neutrino trapping, have been also studied. The interplay between the dominant contribution of the variation of matter composition and the role of effective masses of mesons and nucleons leads to higher critical densities for matter with neutrino trapping. Furthermore, the predicted critical density is insensitive to the number of trapped neutrinos as well as to the RMF model used in the investigation. It is also found that additional nonlinear terms in the Horowitz-Piekarewicz and Furnstahl-Serot-Tang models prevent another kind of instability, which occurs at relatively high densities. The reason is that the effective sigma meson mass in their models increases as a function of the matter density.

description: This study compares federal, provincial and First Nations schools’ delivery of educa­ tional services to native students in Northwestern Ontario. Areas of comparison include curriculum and standards, staffing, staff support and supervision, and student support services. The results of the study indicated that all three educational systems have programs in place to provide the above educational services to the Native students enroled in their schools. There are, however, significant differences among the systems in the manner in which these services are implemented.

description: In order to provide a firm identification of the newly discovered Galactic TeV sources, a search for counterparts in a broad band from soft X-ray to soft gamma-rays is crucial as data in these wavebands allow us to distinguish between different types of suggested models (for example leptonic versus hadronic) and, in turn, to disentangle their nature. In this paper, we report the results of a set of follow-up observations performed by the Swift/X-Ray Telescope (XRT) on seven sources recently discovered by HESS, in the range from few hundred GeV to about 10 TeV, during the inner Galaxy survey (Aharonian et al. 2006). In all, but one case, we detect X-ray sources inside or close-by the extended TeV emitting region. All these putative X-ray counterparts have accurate arc-second location and are consistent with being point sources. The main result of our search is the discovery that three of them are located at the center of the diffuse radio emission of the supernova remnants, which have been spatially associated to these TeV objects. HESS J1640-465, HESS J1834-087 and HESS J1813-178 show this evidence, suggestive of a possible Pulsar Wind Nebula association.

description: Within the framework of the kinetic energy driven d-wave superconductivity, the electronic structure of the electron doped cuprate superconductors is studied. It is shown that although there is an electron-hole asymmetry in the phase diagram, the electronic structure of the electron-doped cuprates in the superconducting-state is similar to that in the hole-doped case. With increasing the electron doping, the spectral weight in the $(π,0)$ point increases, while the position of the superconducting quasiparticle peak is shifted towards the Fermi energy. In analogy to the hole-doped case, the superconducting quasiparticles around the $(π,0)$ point disperse very weakly with momentum.

description: Imaging surveys of CO and other molecular transition lines are fundamental to measuring the large-scale distribution of molecular gas in the Milky Way. Due to finite angular resolution and sensitivity, however, observational effects are inevitable in the surveys, but few studies are available on the extent of uncertainties involved. The purpose of this work is to investigate the dependence of observations on angular resolution (beam sizes), sensitivity (noise levels), distances, and molecular tracers. To this end, we use high-quality CO images of a large-scale region (25.8

Generating optical supercontinuum and frequency comb in tenuous plasmas

description: There are several mechanisms by which the frequency spectrum of a laser broadens when it propagates at near-relativistic-intensity in tenuous plasma. Focusing on one dimensional effects, we identify two strong optical nonlinearities, namely, four-wave mixing (FWM) and forward Raman scattering (FRS), for creating octave-wide spectra. FWM dominates the interaction when the laser pulse is short and intense; Its combination with phase modulation produces a symmetrically broadened supercontinuum. FRS dominates when the laser pulse is long and relatively weak; It broadens the laser spectrum mainly towards lower frequencies and produces a frequency comb. The creation of the supercontinuum and frequency combs only frequency modulates, but does not compress, the laser pulse.

description: We study the effect of polarization in Axelrod's model of cultural dissemination. This is done through the introduction of a cultural feature that takes only two values, while the other features can present a larger number of possible traits. Our numerical results and mean-field approximations show that polarization reduces the characteristic phase transition of the original model to a finite-size effect, since at the thermodynamic limit only the ordered phase is present. Furthermore, for finite system sizes, the stationary state depends on the percolation threshold of the network where the model is implemented: a polarized phase is obtained for percolation thresholds below 1/2, a fragmented multicultural one otherwise.

description: Η μελέτη των βασικών χρωματικών όρων από τους Berlin and Kay (1969) αποτέλεσε την αφετηρία για την εκτενή διερεύνηση του λεξιλογίου των χρωμάτων. Ωστόσο, η μελέτη των αντίστοιχων ελληνικών όρων έχει περιοριστεί στην Αρχαία Ελληνική Γλώσσα. Σκοπός της παρούσας διατριβής είναι να διερευνήσει τους χρωματικούς όρους άσπρος και λευκός της Νέας Ελληνικής Γλώσσας μέσα στο θεωρητικό πλαίσιο της Γνωστικής Γλωσσολογίας. Χρησιμοποιώντας υλικό απο τον Εθνικό Θησαυρό Ελληνικής Γλώσσας καθώς και ετυμολογίες λεξικών οι δυο όροι μελετήθηκαν ονοματολογικά και σηματολογικά ούτως ώστε να δοθεί μια ολοκληρωμένη περιγραφή της χρήσης τους. Η ονοματολογική προσέγγιση εξετάζει εάν οι δυο όροι αποτελούν περίπτωση συνωνυμίας και συγκρίνει την κατανομή των δυο όρων σε διαφορετικά σημασιολογικά πεδία. Η σηματολογική προσέγγιση εμβαθύνει στις διαφορετικές σημασίες του κάθε όρου, οι οποίες παρουσιάζονται με τη μορφή ακτινωτών δικτύων
description: Since Berlin and Kay’s (1969) study on basic color terms, the subject of color vocabulary has been extensively researched. Nevertheless, the study of color terms in the Greek language has been restricted to Ancient Greek. The aim of this thesis is to investigate the Greek Color terms άσπρος and λευκός within the framework of Cognitive Linguistics. Using material from the Hellenic National Corpus as well as etymologies from dictionaries, both terms are studied from an onomasiological and semasiological perspective in order to provide a comprehensive account of their usages. On the one hand, the onomasiological approach examines whether these two terms should be considered synonymous and compares the distribution of άσπρος and λευκός in different semantic fields. On the other, the semasiological approach delves into the distinct meanings of each color term ,which are presented in the form of radial networks

description: We present the Heraklion Extragalactic Catalogue, or HECATE, an all-sky value-added galaxy catalogue, aiming to facilitate present and future multi-wavelength and multi-messenger studies in the local Universe. It contains 204,733 galaxies up to a redshift of 0.047 (D<200 Mpc), and it is >50% complete in terms of the B-band luminosity density at distances in the 0-170 Mpc range. By incorporating and homogenising data from astronomical databases and multi-wavelength surveys, the catalogue offers positions, sizes, distances, morphological classifications, star-formation rates, stellar masses, metallicities, and nuclear activity classifications. This wealth of information can enable a wide-range of applications, such as: (i) demographic studies of extragalactic sources, (ii) initial characterisation of transient events, and (iii) searches for electromagnetic counterparts of gravitational-wave events. The catalogue is publicly available to the community at a dedicated portal, which will also host future extensions in terms of the covered volume, and data products.

Anxiety in Language Learning: Recognition and Prevention
Creators: name: Proulx, Paul
Publisher: name: Canadian Journal of Native Education
Year: 2021

description: The high levels of anxiety found in some educational environments are an almost insuperable block to effective learning. So called facilitating stress is only rarely a useful pedagogical device, since it requires a high level of student self confidence and only operates in the later stages of certain types of learning. Anxiety among students leads to poor performance and hostility, which threaten the teacher’s professional self esteem. Unconscious retaliation under various rationalizations aggravates the problem. Appropriate responses include early identification of the problem, avoiding the escalation of mutual hostility, therapeutic management of stress—but especially prevention. In an experiment in stress prevention and management at a Canadian university, the usefulness of personal acquaintance with students, realistic reassurance, and the avoidance of threatening behaviours were assessed. Five case histories illustrate the successes and limits of this approach.

Private and Resource-Bounded Locally Decodable Codes for Insertions and Deletions

description: We construct locally decodable codes (LDCs) to correct insertion-deletion errors in the setting where the sender and receiver share a secret key or where the channel is resource-bounded. Our constructions rely on a so-called "Hamming-to-InsDel" compiler (Ostrovsky and Paskin-Cherniavsky, ITS '15 & Block et al., FSTTCS '20), which compiles any locally decodable Hamming code into a locally decodable code resilient to insertion-deletion (InsDel) errors. While the compilers were designed for the classical coding setting, we show that the compilers still work in a secret key or resource-bounded setting. Applying our results to the private key Hamming LDC of Ostrovsky, Pandey, and Sahai (ICALP '07), we obtain a private key InsDel LDC with constant rate and polylogarithmic locality. Applying our results to the construction of Blocki, Kulkarni, and Zhou (ITC '20), we obtain similar results for resource-bounded channels; i.e., a channel where computation is constrained by resources such as space or time.
Interior of a Schwarzschild black hole revisited

description: The Schwarzschild solution has played a fundamental conceptual role in general relativity, and beyond, for instance, regarding event horizons, spacetime singularities and aspects of quantum field theory in curved spacetimes. However, one still encounters the existence of misconceptions and a certain ambiguity inherent in the Schwarzschild solution in the literature. By taking into account the point of view of an observer in the interior of the event horizon, one verifies that new conceptual difficulties arise. In this work, besides providing a very brief pedagogical review, we further analyze the interior Schwarzschild black hole solution. Firstly, by deducing the interior metric by considering time-dependent metric coefficients, the interior region is analyzed without the prejudices inherited from the exterior geometry. We also pay close attention to several respective cosmological interpretations, and briefly address some of the difficulties associated to spacetime singularities. Secondly, we deduce the conserved quantities of null and timelike geodesics, and discuss several particular cases in some detail. Thirdly, we examine the Eddington-Finkelstein and Kruskal coordinates directly from the interior solution. In concluding, it is important to emphasize that the interior structure of realistic black holes has not been satisfactorily determined, and is still open to considerable debate.

description: The Stokes-Brinkman equations model fluid flow in highly heterogeneous porous media. In this paper, we consider the numerical solution of the Stokes-Brinkman equations with stochastic permeabilities, where the permeabilities in subdomains are assumed to be independent and uniformly distributed within a known interval. We employ a truncated anchored ANOVA decomposition alongside stochastic collocation to estimate the moments of the velocity and pressure solutions. Through an adaptive procedure selecting only the most important ANOVA directions, we reduce the number of collocation points needed for accurate estimation of the statistical moments. However, for even modest stochastic dimensions, the number of collocation points remains too large to perform high-fidelity solves at each point. We use reduced basis methods to alleviate the computational burden by approximating the expensive high-fidelity solves with inexpensive approximate solutions on a low-dimensional space. We furthermore develop and analyze rigorous a posteriori error estimates for the reduced basis approximation. We apply these methods to 2D problems considering both isotropic and anisotropic permeabilities.

Spin Nernst Effect of Antiferromagnetic Magnons in the Presence of Spin Diffusion

description: Magnon spin Nernst effect was recently proposed as an intrinsic effect in antiferromagnets, where spin diffusion and boundary spin transmission have been ignored. However, diffusion processes are essential to convert a bulk spin current into boundary spin accumulation, which determines the spin injection rate into detectors through imperfect transmission. We formulate a diffusive theory to describe the detection of magnon spin Nernst effect with boundary conditions reflecting real device geometry. Thanks to the spin diffusion effect, the output signals in both electronic and optical detection grow rapidly with an increasing system size in the transverse dimension, which eventually saturate. Counterintuitively, the measurable signals are even functions of magnetic field, yielding optical detection more favorable than electronic detection.

description: We investigate the graviton propagator in the type IIB supergravity background which is dual to 4 dimensional noncommutative gauge theory. We assume that the boundary is located not at the infinity but at the noncommutative scale where the string frame metric exhibits the maximum. We argue that the Neumann boundary condition is the appropriate boundary condition to be adopted at the boundary. We find that the graviton propagator behaves just as that of the 4 dimensional massless graviton. On the other hand, the non-analytic behaviors of the other Kaluza-Klein modes are not significantly affected by the Neumann boundary condition.

description: The main purpose of this study was to determine if a difference, in terms of academic self-concept, could be found between Native students who attended a band-controlled school and those who attended a public school. Of secondary interest was whether the two groups of students would differ in terms of the academic aspirations which they perceived their parents and favourite teacher held for them. The students in this study were from a Western reserve and included 20 students in grades 8 through 12 who attended a band-controlled school and 22 students who attended a public school in a nearby town. The results indicated that (1) significant differences in self-concept scores were not found; and (2) students attending the Native-controlled school perceived that their parents and favourite teacher held significantly higher levels of educational aspirations for them than did students who attended the public school.

description: We study the stellar halos of $0.2\lesssim z \lesssim 0.5$ galaxies with stellar masses spanning $M_*\sim 10^{10.5}$ to $10^{12}M_\odot$ (approximately $L_*$ galaxies at this redshift) using imaging data from the Cosmic Infrared Background Experiment (CIBER). A previous CIBER fluctuation analysis suggested that intra-halo light (IHL) contributes a significant portion of the near-infrared extragalactic background light (EBL), the integrated emission from all sources throughout cosmic history. In this work, we carry out a stacking analysis with a sample of $\sim$30,000 Sloan Digital Sky Survey (SDSS) photometric galaxies from CIBER images in two near-infrared bands (1.1 and 1.8 $μ$m) to directly probe the IHL associated with these galaxies. We stack galaxies in five sub-samples split by brightness, and detect an extended galaxy profile, beyond the instrument point spread function (PSF), derived by stacking stars. We jointly fit a model for the inherent galaxy light profile, plus large-scale one- and two-halo clustering to measure the extended galaxy IHL. We detect non-linear one-halo clustering in the 1.8 $μ$m band, at a level consistent with numerical simulations. Our results on the galaxy profile suggest that $\sim 50\%$ of the total galaxy light budget in our galaxy sample resides in the outskirts of the galaxies at $r > 10$ kpc. We describe this extended emission as IHL and and are able to study how this fraction evolves with cosmic time. These results are new in the near-infrared wavelength at the $L_*$ mass scale, and suggest that IHL has a significant contribution to the integrated galactic light, and to the amplitude of large-scale background fluctuations.

Η περίπτωση που μελετήθηκε είναι το νησί της Λέσβου, ένα νησί του βορειοανατολικού Αιγαίου στην Ελλάδα, το τρίτο μεγαλύτερο νησί της Ελλάδας. Ο κύριος στόχος της έρευνας είναι να αναζητηθούν οι αιτίες για rebranding και οι τρόποι και στρατηγικές που θα πρέπει να εφαρμοστούν για επιτυχημένο επανασχεδιασμό της επικοινωνιακής προβολής. Αυτό το νησί είναι ιδιαίτερα ενδιαφέρον λόγω της συνεχούς εμφάνισής του στα μέσα επικοινωνίας από την αρχή της κρίσης. Αυτό οφείλεται κυρίως στο γεγονός ότι το νησί της Λέσβου αποτελεί το κοντινότερο σημείο όπου φτάνουν πολλοί μετανάστες από την Τουρκία και επειδή το νησί φιλοξενεί μια από τις πιο γνωστές δομές φιλοξενίας, την Moria. Η δομή αυτή ήταν και εξακολουθεί να είναι το αντικείμενο πολλών αντιπαραθέσεων και λόγω της φήμης της συχνά απεικονίζεται αρνητικά στα παγκόσμια μέσα ενημέρωσης. Η αρνητική κάλυψη των μέσων μαζικής ενημέρωσης και η συσχέτιση της Moria με το νησί επηρέασαν την εικόνα του νησιού στα μάτια των τουριστών και των περιστασιακών παραθεριστών, ενώ παράλληλα καθιστούν τον πρωταρχικό προορισμό για ανθρωπιστικούς και ΜΚΟ εργαζόμενους με προγράμματα βοήθειας που βοηθούν τους μετανάστες να διασχίσουν την Ευρώπη να τους παράσχει βασικές ανάγκες
description: This research has a goal of representing the rebranding strategy of places affected by immigration crisis, which started in 2015 and is still ongoing. The case researched is Lesvos island, an Aegean island located in North-Eastern part of Aegean sea in Greece, the third largest island in Greece. The main focus of the research is finding the finding the causes as to why rebranding is needed and ways in which rebranding can be done and which strategies should be implemented. This island is particularly interesting due to its constant appearance in the media since the start of the crisis. This is mostly because this island marks the first place where many immigrants first come to European land, its proximity to Turkey, and because the island is the host of one of the most notorious immigrant camp- the Moria camp. This camp was, and still is the subject of many controversies and due to its reputation and is often portrayed negatively in the worldwide media. Negative media coverage and the negative camp’s association with the island affected the island’s image in the eyes of tourists and casual holiday makers, while at the same time making it a prime destination for humanitarian and NGO workers working with relief programs helping immigrants cross to Europe and provide them with basic necessities

The $\mathsf{FDR}$ is the expected False Discovery Proportion ($\mathsf{FDP}$), that is, the expected fraction of false rejections among all rejected hypotheses. A number of refinements to the original Benjamini-Hochberg procedure [1] have been proposed, to increase power by estimating the proportion of true null hypotheses, either implicitly, leading to one-stage adaptive procedures [4, 7] or explicitly, leading to two-stage adaptive (or plug-in) procedures [2, 21]. We use a variant of the stochastic process approach proposed by Genovese and Wasserman [11] to study the fluctuations of the $\mathsf{FDP}$ achieved with each of these procedures around its expectation, for independent tested hypotheses. We introduce a framework for the derivation of generic Central Limit Theorems for the $\mathsf{FDP}$ of these procedures, characterizing the associated regularity conditions, and comparing the asymptotic power of the various procedures. We interpret recently proposed one-stage adaptive procedures [4, 7] as fixed points in the iteration of well known two-stage adaptive procedures [2, 21].

description: A mannose-resistant hemagglutinating (erythrocyte aggregating)protein was cloned from Escherichia coli 09:H10:K99. This hemagglutinin was determined to be different from the two mannose-resistant hemagglutinins that this strain was known to possess, F41 and K99, and was named Heat Resistant Agglutinin 1 (HRA1) on the basis of one of its physical properties. The HRA1 gene present on the recombinant plasmidpETE1 was localized and identified unambiguously by subcloning. The nucleotide sequence of the gene was determined and found to consist of a 792 base pair open reading frame coding for a protein of 29 kDa. This protein has a predicted prokaryotic N-terminal secretory signal sequence. The protein sequence derived from the genetic information showed no significant similarity to database protein sequences. Physical and chemical attempts to isolate HRA1 from the cell membrane met with limited success. N-terminal sequence analysis of a pronounced 25 kDa band present on polyacrylamide gels of crude membrane preparations of bacteria harbouring pETE1 correlated with the predicted N-terminal amino acid sequence of HRA1 after cleavage of the signal peptide. Four other open reading frames were found on the cloned DNA fragment. Three of the deduced proteins from these regions contained predicted signal sequences and membrane associated areas and one showed50 % identity with E.coli lipoprotein, suggesting that a region of DNA associated with outer membrane structure and function was cloned. Partition in various aqueous two-phase polymer systems showed that expression of HRA1 caused pronounced cell-surface changes in host bacteria. Viscometric analysis showed that the agglutination event mediated by HRA1 was less pronounced than that of F41. This was likely due to the fact that F41 is known to be an exposed high molecular weight multivalent adhesin, whereas evidence suggests that HRA1 is a monovalent molecule that is closely associated with the bacterial membrane.

description: Mayall II = G1 is one of the most luminous globular clusters (GCs) known in M31. New deep, high-resolution observations with the Advanced Camera for Surveys on the {\sl Hubble Space Telescope} are used to provide accurate photometric data to the smallest radii yet. In particular, we present the precise variation of ellipticity and position angle, and of surface brightness for the core of the object. Based on these accurate photometric data, we redetermine the structural parameters of G1 by fitting a single-mass isotropic King model. We derive a core radius, $r_c=0.21\pm0.01\arcsec (=0.78\pm0.04 \rm{pc})$, a tidal radius, $r_t=21.8\pm1.1\arcsec (=80.7\pm3.9 \rm{pc})$, and a concentration index $c=\log (r_t/r_c)=2.01\pm0.02$. The central surface brightness is 13.510 mag arcsec$^{-2}$. We also calculate the half-light radius, at $r_h=1.73\pm0.07\arcsec(=6.5\pm0.3 \rm{pc})$. The results show that, within 10 core radii, a King model fits the surface brightness distribution well. We find that this object falls in the same region of the $M_V$ vs. $\log R_h$ diagram as $ω$ Centauri, M54 and NGC 2419 in the Milky Way. All three of these objects have been claimed to be the stripped cores of now defunct dwarf galaxies. We discuss in detail whether GCs, stripped cores of dwarf spheroidals and normal dwarf galaxies form a continuous distribution in the $M_V$ versus $\log R_h$ plane, or if GCs and dwarf spheroidals constitute distinct classes of objects; we present arguments in favour of this latter view.

description: We develop a theory of nonlinear response to an electric field of a two-dimensional electron gas (2DEG) placed in a classically strong magnetic field. The latter leads to a non-linear current-voltage characteristic at a relatively weak electric field. The origin of the non-linearity is two-fold: the formation of a non-equilibrium electron distribution function, and the geometrical resonance in the inter-Landau-levels transitions rates. We find the dependence of the current-voltage characteristics on the electron relaxation rates in the 2DEG.

and Security in International Cooperation in Rwanda.

description: The times following international or civil conflicts but also violent revolutions often come with unequal share of the peace dividend for men and women. Delusions for women who gained freedom of movement and of roles during conflict but had to step back during reconstruction and peace have been recorded in all regions of the world. The emergence of peacebuilding as a modality for the international community to ensure peace and security has slowly incorporated gender sensitivity at the level of legal and policy instruments. Focusing on Rwanda, a country that has obtained significant gender advancement in the years after the genocide while also obtaining to not relapse into conflict, this research explores to what extent the international community has contributed to this transformation. From a review of evaluations, findings are that many of the interventions did not purse gender equality, and overall the majority understood gender and designed actions is a quite superficial way which would hardly account for the significative advancement in combating gender discrimination that the Government, for its inner political will, is conducting. Then, after a critique from a feminist standpoint to the concept of human security, departing from the assumption (sustained by the Governemnt of Rwanda as well) that domestic violence is a variable influencing level of security relevant at the national level, a review of available secondary data on GBV is conducted an trends over the years analysed. The emerging trends signal a steep increase in prevalence of GBV and in domestic violence in particular. Although no conclusive interpretation can be formulated on these data, there are elements suggesting the increase might be due to augmented reporting. The research concludes outlining possible further research pathways to better understand the link in Rwanda between the changing gender norms and the GBV.
Renormalization-Group Evolution of the None-local Matrix Element of $B$-meson In QCD and $B\to π$ transition form factor

description: We consider the renormalization-group evolution of the matrix element of $\langle 0| \bar{q}(z)_β[z,0]b(0)_α| \bar{B}\rangle$, which can be used to define the distribution amplitudes for $B$ meson and widely applied in studies of $B$ meson decays. The contribution to the renormalization constant of the non-local operator $\bar{q}(z)_β[z,0]b(0)_α$ is considered up to one-loop order in QCD. Since the quark fields in this operator are not directly coupled fields, momentum can not flow freely through this non-local operator. Momentum involved in this operator can be treated stringently in coordinate space. We find that the ultraviolet divergences regulated by dimensional parameter $ε$ cancel with each other, and the evolution effect vanishes. The matrix element $\langle 0| \bar{q}(z)_β[z,0]b(0)_α| \bar{B}\rangle$ escapes from the renormalization-group evolution. We then apply the matrix element in calculating $B\toπ$ transition form factor, where the matrix element is obtained by using the $B$ meson wave function calculated in QCD-inspired potential model. By comparing with experimental data for the semileptonic decay of $B\to π\ellν$ and light-cone sum rule calculation, we analyse the perturbative and non-perturbative contributions to $B\toπ$ transition form factor in the frame work of perturbative QCD approach. We find that the effectiveness of the suppression of Sudakov factor to soft contribution depends on the end-point behavior of $B$ meson wave function, and with the $B$-meson wave function used in this work, soft contribution can not be well suppressed. The hard contribution to the $B\toπ$ transition form factor is about 59\%, and soft contribution can be as large as 41\% in the naive calculation. To make the perturbative calculation reliable, a soft momentum cutoff in the calculation and soft form factor have to be introduced.

description: We present the discovery of 2MASS J21321145+1341584AB as a closely separated (0.066") very low-mass field dwarf binary resolved in the near-infrared by the Keck II Telescope using laser guide star adaptive optics. Physical association is deduced from the angular proximity of the components and constraints on their common proper motion. We have obtained a near-infrared spectrum of the binary and find that it is best described by an L5+/-0.5 primary and an L7.5+/-0.5 secondary. Model-dependent masses predict that the two components straddle the hydrogen burning limit threshold with the primary likely stellar and the secondary likely substellar. The properties of this sytem - close projected separation (1.8+/-0.3 AU) and near unity mass ratio - are consistent with previous results for very low-mass field binaries. The relatively short estimated orbital period of this system (~7-12 yr) makes it a good target for dynamical mass measurements. Interestingly, the system's angular separation is the tightest yet for any very low-mass binary published from a ground-based telescope and is the tightest binary discovered with laser guide star adaptive optics to date.

Total syntheses of (+̲)-Methyl cantabrenonate, (+̲)-Methyl epoxycantabronate, and (+̲)-Crinipellin B
Creators: name: Renaud, Johanne
Publisher: name: University of British Columbia
Year: 2008

description: The syntheses of two structurally related target compounds, (±)-methyl cantabrenonate(13) and (±)-methyl epoxycantabronate (14) are described in the first part of this thesis, while the preparation of the naturally occurring crinipellin B (15) is discussed in the second part of the thesis. Two methylenecyclopentane annulation sequences previously developed in our laboratories played key roles in the syntheses of (±)-13, (±)-14 and (±)-15. A new cyclopentenone annulation procedure was elaborated to assemble the last 5-membered ring of crinipellin B (15). The syntheses of (±)-13 and (±)-14 first involved the conversion of 3-methy1-2-cyclopenten- 1-one (64) into the enone 62 via known chemistry. The enone 62 was transformed into the keto alkene 60 in one step utilizing a methylenecyclopentane annulation method developed previously by Piers and Karunaratne. Thus, conjugate addition of the reagent 18 to the enone 62 afforded the lithium enolate anion 106. This intermediate was allowed to undergo intramolecular alkylation, upon addition of HMPA to the solution containing 106 and warming to room temperature. The keto alkene 60 was converted into the ketone 59 via a sequence of steps which allowed establishment of the correct configuration of the methyl group at C-9. Three synthetic operations on the ketone 59 afforded the enone 120which was successfully transformed into (±)-13 and (±)-14. The synthesis of (±)-crinipellin B (15) was accomplished in 22 steps from the commercially available 2-methyl-2-cyclopenten- 1-one. The starting material was efficiently converted into the bicyclic enone 194 which was subjected to a methylenecyclopentane annulation sequence regioisomeric to that described above. Thus, treatment of 194 with the reagent 209 in the presence of TMSBr provided the vinyl germane 219. A trimethylgermyl-iodine exchange on 219 afforded the vinyl iodide 220, which was allowed to cyclize under conditions ((Ph3)4Pd, t-BuOK, t-BuOH, THF) developed previously by Piers and Marais. The keto alkene 191 was obtained in good overall yield from 194. Three synthetic operations on 191 yielded the ketone 224. A newly elaborated cyclopentenone annulation procedure allowed the conversion of 224 into the enedione 267. Alkylation of 224 with (Z)-3-bromo- 1 -iodopropene (251) gave an intermediate vinyl iodide, which was allowed to undergo cyclization by treatment with n-BuLi in THF. The resultant allylic alcohol 249 underwent oxidative rearrangement to furnish the enedione 267. Two synthetic steps provided the enedione epoxide 188, which was converted into (±)-crinipellin B (15).
