description: We have applied relativistic coupled-cluster (RCC) theory to determine the isotope shift (IS) constants of the first eight low-lying states of the Li, Be$^+$ and Ar$^{15+}$ isoelectronic systems. Though the RCC theory with singles, doubles and triples approximation (RCCSDT method) is an exact method for these systems for a given set of basis functions, we notice large differences in the results from this method when various procedures in the RCC theory framework are adopted to estimate the IS constants. This has been demonstrated by presenting the IS constants of the aforementioned states from the finite-field, expectation value and analytical response (AR) approaches of the RCCSDT method. Contributions from valence triple excitations, Breit interaction and lower-order QED effects to the evaluation of these IS constants are also highlighted. Our results are compared with high-precision calculations reported using few-body methods wherever possible. We find that results from the AR procedure are more reliable than the other two approaches. This analysis is crucial for understanding the roles of electron correlation effects in the accurate determination of IS constants in the heavier atomic systems, where few-body methods cannot be applied.

description: The following paper is aimed at developing students’ BEC Higher writing skills, such as logical development of ideas, clear transitions, well-articulated content, and better control of the language. “Teaching exam classes” specialism is believed to be rather challenging and at the same time extremely rewarding to teach, think and write about, especially if you want to bring this process to a new level. The group of students under consideration is represented by 11 young adults obtaining bachelor degree who are going to take “C1 Business Higher” exam. This exam is included in the students’ educational program because it is accepted by many Russian and European universities if one wants to enroll to a master degree program. Moreover, many companies trust Cambridge assessment quality knowing that the test results are trustworthy.

description: No abstracts are to be cited without prior reference to the author.Turbulence may have inimical effects on phytoplankton cells. Although there are several studies relating small-scale turbulence to dinoflagellate mortality, there are few such studies of diatoms. Field observations in East Sound, Washington suggest that turbulence generated by a modest storm, with wind speeds of approximately 10 m·sec-1, was capable of inflicting massive, species-specific destruction on rriany large and spiny, chain forming diatoms. We hypothesize that wind forcing can create enough small-scale shear in the water column to mechanically break some kinds of large colonial diatoms. To test the effect of small-scale shear on diatoms, laboratory experiments_have been conducted on 20L batch cultures of several taxa representing the genera Pseudonitzschia, Chaetoceros and Odontella. Colonies were grown under quiescent conditions, and then exposed to five levels of quantified turbulence. In most cases, the resulting colony length was related to the level of turbulence. Taxa varied, however, as to whether or not cells were destroyed as colonies fragmented. When turbulence results in cell rupture, it adds a shear-dependent component to the mortality term in equations describing phytoplankton growth dynamics. Aggregation was never observed in our experiments. Our results suggest that differential response to turbulence may affect the floristic composition and succession of marine planktonic diatoms through the direct effect of shear.

Synthesis and conformational studies of 11-(1,3-Dithian-2-YL)-13-tetradecanolide
Creators: name: Spracklin, Douglas Kenneth
Publisher: name: University of British Columbia
Year: 2010

description: 11-(1,3-Dithian-2-yl)-13-tetradecanolide (71) was synthesized in a ten step sequence in approximately 3% overall yield. Alkylation of this compound with methyl iodide yielded a 6:1 mixture of diastereomers 72 and 73, the major isomer being 72. The stereochemistry at C-2 of these compounds was determined by their conversion to 74 and 75. respectively, whose stereochemistry was known. Results of molecular mechanics calculations suggest that the alkylation reaction proceeds through either of the low energy [3335] or [3344] conformations, both of which give rise to the observed product ratio.[See Thesis for Diagram]

description: This paper proposes a Bayesian data-driven machine learning method for the online inference of the parameters of a G-equation model of a ducted, premixed flame. Heteroscedastic Bayesian neural network ensembles are trained on a library of 1.7 million flame fronts simulated in LSGEN2D, a G-equation solver, to learn the Bayesian posterior distribution of the model parameters given observations. The ensembles are then used to infer the parameters of Bunsen flame experiments so that the dynamics of these can be simulated in LSGEN2D. This allows the surface area variation of the flame edge, a proxy for the heat release rate, to be calculated. The proposed method provides cheap and online parameter and uncertainty estimates matching results obtained with the ensemble Kalman filter, at less computational cost. This enables fast and reliable simulation of the combustion process.

description: The following paper is aimed at developing students’ story-telling skills. The choice of this topic is conditioned by the fact that sharing stories is important in our daily interactions. However, even when students reach a high level of English, they may lack the strategies that would help them tell stories, for instance in a form of an anecdote, in such a way that a listener would be engaged. This essay shall be focused primarily on the relevant features of storytelling which occurs in an informal setting, as this shall be the most relevant aspect of storytelling for the students. An authentic speaking practice, as well as engagement, help developing learners’ speaking abilities. Therefore, it is suggested that evaluating the language, discovered within an anecdote, guides learners to become more independent and confident.

Driver Choice Compared to Controlled Diversion for a Freeway Double On-Ramp
Creators: name: Davis, L. C.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Physics and Society (physics.soc-ph)
subject: FOS: Physical sciences

description: Two diversion schemes that apportion demand between two on-ramps to reduce congestion and improve throughput on a freeway are analyzed. In the first scheme, drivers choose to merge or to divert to a downstream on-ramp based on information about average travel times for the two routes: (1) merge and travel on the freeway or (2) divert and travel on a surface street with merging downstream. The flow, rate of merging at the ramps, and the travel times oscillate strongly, but irregularly, due to delayed feedback. In the second scheme, diversion is controlled by the average mainline velocities just upstream of the on-ramps. Driver choice is not involved. If the average upstream velocity on the mainline drops below a predetermined value (20 m/s) vehicles are diverted to the downstream ramp. When the average mainline velocity downstream becomes too low, diversion is no longer permitted. The resultant oscillations in this scheme are nearly periodic. The period is dominated by the response time of the mainline to interruption of merging rather than delayed feedback, which contributes only a minor component linear in the distance separating the on-ramps. In general the second scheme produces more effective congestion reduction and greater throughput. Also the travel times for on-ramp drivers are less than that obtained by drivers who attempt to minimize their own travel times (first scheme).

Photochemistry of some naphthoquinols in solid polymer matrices
Creators: name: Gudmundsdóttir, Anna Dóra
Publisher: name: University of British Columbia
Year: 2010

description: The main objective of this work was to study how polymer media can modify the photochemical reactivity of dissolved guest molecules. Three tetrahydronaphthoquinols, whose photochemistry is known to be sensitive to the reaction medium, were synthesized for this study. The photochemistry of these compounds consisted of [2 + 2] cycloaddition in solution and hydrogen abstraction-initiated rearrangement in the solid state. Different photopro-ducts from solution and solid state photolysis were interpreted as being due to reaction from different conformers in the different media. 2,3,4aα,6,7,8aα-hexamethyl-4a,5,8,8a-tetrahydronaphthoquin- l-on-4β-ol, studied in poly(methyl methacrylate) and poly(vinyl acetate) films, was found to exhibit behavior that is intermediate to solution and solid state reactivity and is discontinuous at the glass transition temperature. 2,3,4aα,6,7,8aα-hexamethyl-4a,5,8,8a-tetrahydronaphthoquin-l-on-4α-ol, which was essentially unreactive in the solid state, was also studied. It was found to give the expected but not observed solid state product as the major product in poly(methyl methacrylate). Finally, 2 , 3 ,4aα ,6,7, 8aα:-4a ,5,8, 8a- tetrahydronaphthoquin-1-on-4β-acetate was studied. As a result of differences in the local enviroment, this compound displayed unique photoreactivity in each of three different media: in solution it gave 5-exo-acetoxy-l,3,4,6,8,9-hexamethyltetracyclo [4.4.0.0[sup 3,9].0[sup 4,8]decan-2-one, in the pure crystalline phase it gave 5-exo-acetoxy-2-oxy-1,3,4,6,8,9-hexamethyltricyclo[4.4.0.0[sup 4,7]-dec-8-en -2-one and in poly(methyl methacrylate) films 5-exo-acetoxy-1,3,4,6,8,9-hexamethyltetracyclo[4.4.0.0[sup 3,7]dec-8-en-2-one, as a major product. It has been demonstrated that polymer matrices are useful reaction media for reducing the rates of conformational interconversions to the point that alternative chemical processes that are normally too slow to be observed in solution become competitive. This leads to chemical consequences that in some cases mimic those observed in the solid state. In others, where crystals are unreactive for some reasons or where the crystal lattice can sterically impede certain reactions, new products can be formed.

description: We present a theoretical study of a Berezinskii-Kosterlitz-Thouless like phase transition in lattices of nonequilibrium photon condensates. Starting from linearized fluctuation theory and the properties of vortices, we propose an analytical formula for the critical point containing four fitting parameters, that captures well all our numerical simulations. We find that the ordered phase becomes more stable when driving and dissipation is increased.

description: The radio nebula W50 is a unique object interacting with the jets of the microquasar SS433. The SS433/W50 system is a good target for investigating the energy of cosmic-ray particles accelerated by galactic jets. We report observations of radio nebula W50 conducted with the NSF's Karl G. Jansky Very Large Array (VLA) in the L band (1.0 -- 2.0 GHz). We investigate the secular change of W50 on the basis of the observations in 1984, 1996, and 2017, and find that most of its structures were stable for 33 years. We revise the upper limit velocity of the eastern terminal filament by half to 0.023$c$ assuming a distance of 5.5 kpc. We also analyze the observational data of the Arecibo Observatory 305-m telescope and identify the HI cavity around W50 in the velocity range 33.77 km s$^{-1}$ -- 55.85 km s$^{-1}$. From this result, we estimate the maximum energy of the cosmic-ray protons accelerated by the jet terminal region to be above 10$^{15.5}$ eV. We also use the luminosity of the gamma-rays in the range 0.5 -- 10 GeV to estimate the total energy of accelerated protons below 5.2 $\times$ 10$^{48}$ erg.

Renormalized q-dependent Spin Susceptibility by inverting the Random Phase Approximation: Implications for quantitative assessment of the role of spin fluctuations in 2D Ising superconductor NbSe$_{2}$

description: Accurate determination of the full momentum-dependent spin susceptibility $χ(\mathbf{q}) $ is very important for the description of magnetism and superconductivity. While in principle the formalism for calculating $χ(\mathbf{q})$ in the linear response density functional theory (DFT) is well established, hardly any publicly available code includes this capability. Here, we describe an alternative way to calculate the static $χ(\mathbf{q})$, which can be applied to most common DFT codes without additional programming. The method combined standard fixed-spin-moment calculations of $χ(\mathbf{0}) $ with direct calculations of the energy of spin spirals stabilized by an artificial Hubbard interaction. From these calculations, $χ_{DFT}(\mathbf{q} )$ can be extracted by inverting the RPA formula. We apply this recipe to the recently discovered Ising superconductivity in NbSe$_2$ monolayer, one of the most exciting findings in superconductivity in recent years. It was proposed that spin fluctuations may strongly affect the parity of the order parameter. Previous estimates suggested proximity to ferromagnetism, $i.e.$, $χ(\mathbf{q})$ peaked at $\mathbf{q}=0$. We find that the structure of spin fluctuations is more complicated, with the fluctuation spectrum sharply peaked at $\mathbf{q}\approx (0.2,0)$. Such a spectrum would change the interband pairing interaction and considerably affect the superconducting state.
Characterization of Concrete Strength, Durability and Workability Impacted by a Super - Plasticizing Additive

description: The purpose of this study is to examine the workability, rate of flow, and compressive strength properties of natural concrete and super-plasticizer concrete over time, taking into account their water-cement ratio. Laboratory tests were conducted on various concrete mixes concerning 0.50, 0.55, and 0.60 water–cement ratios. Different dosages by weight between 0% through 1% of Master Glenium 118 superplasticizers were applied to determine the effects of superplasticizer admixture on the compressive strength and workability of concrete thereafter, the influence of superplasticizer admixture on concrete quality by lowering the amount of mixing water was obtained. Results showed that the addition of the new superplasticizer admixtures to the fresh concrete improved its workability. Hence, the flow rate and slump of natural concrete improve as the water content in the concrete and superplasticizer dosages increase. For hardened concrete's compressive strength test, the result also showed that adding the super-plasticizer admixture into the concrete mix appropriately decreases the weight of the concrete and reduces the strength required in the crushing of the concrete after 7, 14, 21 and 28 days of curing. It is observed that the compressive strength of the natural concrete increase as the curing period increases from 7 to 28 days, and even increase more for the super-plasticizer concrete. More so, the weight of the natural concrete decreases as the curing period increases from 7 to 28 days, and even decreases more for the super-plasticizer concrete thereby producing lightweight concrete which is more durable with a considerably higher economic benefit. The superplasticizer applied in this study significantly maintained the required workability without resorting to excessive water, thus addressing concerns of past studies.

description: [Abridged] We present two-dimensional line-of-sight stellar kinematics of the lens galaxy in the Einstein Cross, obtained with the GEMINI 8m telescope, using the GMOS integral-field spectrograph. The velocity map shows regular rotation up to ~100 km/s around the minor axis of the bulge, consistent with axisymmetry. The velocity dispersion map shows a weak gradient increasing towards a central (R<1") value of sigma_0=170+/-9 km/s. We deproject the observed surface brightness from HST imaging to obtain a realistic luminosity density of the lens galaxy, which in turn is used to build axisymmetric dynamical models that fit the observed kinematic maps. We also construct a gravitational lens model that accurately fits the positions and relative fluxes of the four quasar images. We find that the resulting luminous and total mass distribution are nearly identical around the Einstein radius R_E = 0.89", with a slope that is close to isothermal, but which becomes shallower towards the center if indeed mass follows light. The dynamical model fits to the observed kinematic maps result in a total mass-to-light ratio (M/L)_dyn=3.7+/-0.5 M_sun/L_sun,I (in the I-band). This is consistent with the Einstein mass M_E = 1.54 x 10^10 M_sun divided by the (projected) luminosity within R_E, which yields a total mass-to-light ratio of (M/L)_E=3.4 M_sun/L_sun,I, with an error of at most a few per cent. We estimate from stellar populations model fits to colors of the lens galaxy a stellar mass-to-light ratio (M/L)_* from 2.8 to 4.1 M_sun/L_sun,I. Although a constant dark matter fraction of 20 per cent is not excluded, dark matter may play no significant role in the bulge of this ~L* early-type spiral galaxy.

description: No abstracts are to be cited without prior reference to the author.After the Second World War, the only Polish rivers known to be spawning areas for theAtlantic salmon were: tertiary tributary of the Odra River-the Drawa and the left banktributary of the latter-the Plociczna. Within the ~pawning, taking place mainly in the secondand third decade of November, the bright spots of characteristic shape are formed in the river.They are the spawning sites, that can be counted. The main goal of the present paper was toquantifY the spawning sites occurring in the Drawa within 1976-1996. They were studied at thetwo river stretches: 3.7-km-long Drawa section below the weir in the village ofKamienna and2.5-km-long section of the lower Plociczna River, below Ostrowiec Lake. It turned out thatwithin 1976-1985 and 1988 there were 79-2 spawning sites, predominately large, noticed inthe lower Drawa and Plociczna. On the other hand, within 1986-1987 and within 1989-1996,the. spawning sites were not revealed. The number of the spawning sites was distinctlydeclining from 79 in the season of 1985 to 2 in the season of 1988 (Tab. 1). It is presentlysuggested that the major cause of the disappearance of the spawning sites in the Drawa andPlociczna was high fishing mortality of the grown saImon in the Baltic Sea and on the inlandroute oftheir migration-the lower Odra River system in particular.

description: We report the detection, for the first time in space, of cyano thioformaldehyde (HCSCN) and propynethial (HCSCCH) towards the starless core TMC-1. Cyano thioformaldehyde presents a series of prominent a- and b-type lines, which are the strongest previously unassigned features in our Q-band line survey of TMC-1. Remarkably, HCSCN is four times more abundant than cyano formaldehyde (HCOCN). On the other hand, HCSCCH is five times less abundant than propynal (HCOCCH). Surprisingly, we find an abundance ratio HCSCCH/HCSCN of 0.25, in contrast with most other ethynyl-cyanide pairs of molecules for which the CCH-bearing species is more abundant than the CN-bearing one. We discuss the formation of these molecules in terms of neutral-neutral reactions of S atoms with CH2CCH and CH2CN radicals as well as of CCH and CN radicals with H2CS. The calculated abundances for the sulphur-bearing species are, however, significantly below the observed values, which points to an underestimation of the abundance of atomic sulphur in the model or to missing formation reactions, such as ion-neutral reactions.

description: Upcoming measurements of the small-scale primary cosmic microwave background (CMB) temperature and polarization power spectra ($TT$/$TE$/$EE$) are anticipated to yield transformative constraints on new physics, including the effective number of relativistic species in the early universe ($N_{\rm eff}$). However, at multipoles $\ell \gtrsim 3000$, the primary CMB power spectra receive significant contributions from gravitational lensing. While these modes still carry primordial information, their theoretical modeling requires knowledge of the CMB lensing convergence power spectrum, $C_L^{κκ}$, including on small scales where it is affected by nonlinear gravitational evolution and baryonic feedback processes. Thus, the high-$\ell$ primary CMB is sensitive to these late-time, nonlinear effects. Here, we show that inaccuracies in the modeling of $C_L^{κκ}$ can yield surprisingly large biases on cosmological parameters inferred from the primary CMB power spectra measured by the upcoming Simons Observatory and CMB-S4 experiments. For CMB-S4, the biases can be as large as $1.6σ$ on the Hubble constant $H_0$ in a fit to $Λ$CDM and $1.2σ$ on $N_{\rm eff}$ in a fit to $Λ$CDM+$N_{\rm eff}$. We show that these biases can be mitigated by explicitly discarding all $TT$ data at $\ell>3000$ or by marginalizing over parameters describing baryonic feedback processes, both at the cost of slightly larger error bars. We also discuss an alternative, data-driven mitigation strategy based on delensing the CMB $T$ and $E$-mode maps. Finally, we show that analyses of upcoming data will require Einstein-Boltzmann codes to be run with much higher numerical precision settings than is currently standard, so as to avoid similar -- or larger -- parameter biases due to inaccurate theoretical predictions.

description: We obtain an expression for the energy of the density wave propagating in a multicomponent gravitating medium in the form well known from electrodynamics. Using the above, the possibility of "triple production" of the quasi-particles, or waves, with their energies summing up to zero, in a non-equilibrium medium is demonstrated. That kind of resonance wave interaction is shown to result in the development of an explosion instability. By the method developed in plasma physics, the characteristic time of the instability is evaluated.

description: This paper proves the Baum--Katz theorem for sequences of pairwise independent identically distributed random variables with general norming constants under optimal moment conditions. The proof exploits some properties of slowly varying functions and the de Bruijn conjugates, and uses the techniques developed by Rio (1995) to avoid using the maximal type inequalities.

description: The aim of this research is to examine the possible effects of labour market institutional characteristics
on young people's perceptions of their internship experiences as expressed on Twitter. By looking at
these opinions (satisfaction versus dissatisfaction) in relation to certain features of internships as well as to
the more general labour market regulatory framework, this project aims to give a voice to young people,
enabling them (indirectly) to provide policy suggestions to law-makers. Furthermore, we propose a preview
of a possible empirical model for data collection based on the manual coding of Tweets. By employing a
Probit regression and Blinder-Oaxaca and Fairlie decompositions, we have tried to establish a link between
the perceived evaluation of internships and the country where the internship is based, the latter being used
as a proxy for the legal system. In all our tests we found that the country in which the internship is placed
is the main factor in the positive or negative perception. Ultimately we shall propose the use of Twitter
not only as a relevant research tool, but also as an instrument for bringing young people's needs to the
attention of law-makers.

description: No abstracts are to be cited without prior reference to the author.Atlantic salmon were extirpated from the Connecticut River about 200 years ago following the construction ofdams which blocked access to spawning grounds. In the past 25 years state and federal agencies have been attempting to restore anadromous Atlantic salmon tothe Connecticut River by stocking smolts and fry. For the first 20 years ofthe restoration effort, smolts were the primary source offish, but in the last five years emphasis has shifted to frystocking in the tributaries. In 1997, for example, personnel stocked approximately nine million fry into the 29,000 km2 watershed. Primarily because the fry are too small (-25 mm) and numerous to tag or mark with conventional methods, the relative contribution of smolts and adult returns from fish stocked in different tributaries has not been evaluated. Such information is important to help guide wise management decisions.
Collisional relaxation in plasmas
Creators: name: Crossman Statter, Gregory Christopher
Publisher: name: University of British Columbia

description: The energy relaxation of two types of fully ionized plasma systems are determined with the solution of the Fokker-Planck equation. In both cases the plasma constituents are treated as being point-like and structureless and the plasma relaxes collisionally in the absence of spatial gradients and external electric and magnetic fields. The first plasma system consists of one plasma species dilutely dispersed in a second plasma which acts as a heat bath at equilibrium. The initial energy distribution of the dilute constituent is chosen to be a delta function and the approach to a Maxwellian distribution at the heat bath temperature is determined. The second plasma system consists of just one plasma species which initially possesses a bi-Maxwellian ion velocity distribution function (VDF). The average of the kinetic energy, m /2 for particle motions in some arbitrary z direction serves to define a temperature parameter T‖ =m/k for this degree of freedom. Similarly, the temperature T⊥=m/2k, where v⊥ is the velocity component in the plane perpendicular to z, parametrizes the average energy for the other two translational degrees of freedom The relaxation of T‖ and T⊥ to a common temperature, T, via self-collisions of the plasma is studied. In both cases the collisional relaxation can be described by a linear collision operator and the expansion of the distribution function in the eigenfunctions of the Fokker-Planck operator is considered. The reciprocals of the corresponding eigenvalues are the characteristic relaxation times for the system. For the first plasma system, the temperature relaxation time determined with the solution of the Fokker-Planck equation is compared with the relaxation time calculated with the assumption that the distribution function remains Maxwellian all the time. For the second plasma system the relaxation time is the characteristic time for the relaxation of one of the temperature components and is comparedwith the relaxation time calculated with the assumption that the distribution function remains bi-Maxwellian all the time. The results are compared with other theoretical and experimental results. A study of the eigenvalue spectrum of the Fokker-Planck operator and the temporal approach to equilibrium is also emphasized.

description: In a recent work, \cite{cgss}, we developed a functional calculus for bounded operators defined on quaternionic Banach spaces. In this paper we show how the results from \cite{cgss} can be extended to the unbounded case, and we highlight the crucial differences between the two cases. In particular, we deduce a new eigenvalue equation, suitable for the construction of a functional calculus for operators whose spectrum is not necessarily real.

description: In parametric sequence alignment, optimal alignments of two sequences are computed as a function of the penalties for mismatches and spaces, producing many different optimal alignments. Here we give a 3/(2^{7/3}π^{2/3})n^{2/3} +O(n^{1/3} \log n) lower bound on the maximum number of distinct optimal alignment summaries of length-n binary sequences. This shows that the upper bound given by Gusfield et. al. is tight over all alphabets, thereby disproving the "square root of n conjecture". Thus the maximum number of distinct optimal alignment summaries (i.e. vertices of the alignment polytope) over all pairs of length-n sequences is Theta(n^{2/3}).

description: No abstracts are to be cited without prior reference to the author.In Sweden there were originally approximately 40 salmon rivers with wild, self-sustainingpopulations in the Baltic. Original wild salmon populations exist today in 14 rivers, but nativepopulations, uneffected by stockings, are only found in three rivers. Along the Swedish westcoast there were originally approximately 15-20 wild salmon rivers. Wild salmon populationsstill occur in about 15 river systems, but there are only four rivers that have been confim1ed tocontain an original North Atlantic native salmon population. There were three landlockedsalmon populations in Lake Vänem and two of them still exist. The extinction of wild salmonpopulations can be ascribed largely to the combined effects ofdams (hydroelectric a.s.o.),destruction ofhabitats, acidification, water pollution, overfishing and possibly, M74 and otherfish diseases.
A hidden solution to the mu/B_mu problem in gauge mediation

description: We propose a solution to the mu/B_mu problem in gauge mediation. The novel feature of our solution is that it uses dynamics of the hidden sector, which is often present in models with dynamical supersymmetry breaking. We give an explicit example model of gauge mediation where a very simple messenger sector generates both mu and B_mu at one loop. The usual problem, that B_mu is then too large, is solved by strong renormalization effects from the hidden sector which suppress B_mu relative to mu. Our mechanism relies on an assumption about the signs of certain incalculable anomalous dimensions in the hidden sector. Making these assumptions not only allows us to solve the mu/B_mu problem but also leads to a characteristic superpartner spectrum which would be a smoking gun signal for our mechanism.

description: Gauss hypergeometric functions with a dihedral monodromy group can be expressed as elementary functions, since their hypergeometric equations can be transformed to Fuchsian equations with cyclic monodromy groups by a quadratic change of the argument variable. The paper presents general elementary expressions of these dihedral hypergeometric functions, involving finite bivariate sums expressible as terminating Appell's F2 or F3 series. Additionally, trigonometric expressions for the dihedral functions are presented, and degenerate cases (logarithmic, or with the monodromy group Z/2Z) are considered.

Bis(ethene)rhodium(I) [beta]-diketonates and related complexes, catalytic and ¹H NMR spectroscopic studies
Creators: name: Wickenheiser, Eugene Benedict
Publisher: name: University of British Columbia
Year: 2010

description: A series of bis(ethene)rhodium(I) complexes of β-diketonates and similar ligands were prepared. The complexes were characterized by elemental analysis, ¹H NMR spectroscopy and mass spectrometry. Crystal structures are reported for bis(η²-ethene)-(1,3(1-ferrocenyl)butanedionato-0.0 ')rhodium(I), 13, (1,5-cyclooctadieiie)(2-acetylphen-oxy-0,0')rhodium(I),18, and some related molecules. [FORMULA OMITTED] The complexes are catalyst precursors for the homogeneous hydrogenation of olefins and the hydrosilylation of ketones. The generated hydrogenation catalysts are effective for the reduction of sterically unhindered carbon-carbon double bonds. These catalysts are active in the presence of alcohol, aromatic and carboxylic acid functional groups on the olefin substrate. The catalysts decompose to give a heterogeneously active rhodium precipitate when reducing olefinic substrates which are too sterically hindered. Study of the hydrosilylation reaction revealed that the complexes generate active hydrosilylation catalysts. A series of optically active ligands were tested for their ability to effect asymmetry in the silyl ether products. The bis(ethene)rhodium(I) complexes are fluxional in the NMR time scale due to the motion of the ethylene ligands. A detailed ¹H NMR study was conducted on one of the complexes, bis(η²-ethene)(2-acetylphenoxy-0,0 ')rhodium(I) 15 to explore the nature of the rearrangement. [FORMULA OMITTED] The ¹H NMR study revealed the presence of two different modes of fluxionality. The first type of motion is intramolecular in nature and is due to the rotation of the ethylene ligands about the rhodium-ethylene bond axis. The second type is intermolecular in nature and is due to exchange of the ethylene ligands. This exchange is a measure of the lability of the ethylene ligands. The system allowed the separate study of the ethylene ligands and ΔG‡ values were obtained for each ligand for both of the exchange processes. The results of the study indicate the independance of the ethylene ligands with respect to both fluxional processes.

description: No abstracts are to be cited without prior reference to the author.Characterisation of stocks is essential for fisheries and environmental management inorder to conserve genetic diversity. However, classical population genetic methods frequently failto document stock differences. In this paper we list a number ofcharacters that were used tocompare the performance ofthe offspring of three adjacent river stocks during the freshwaterperiod in culture until release, and their returns as adults. The emphasis will be put on life historytraits and their consequences for growth and fishing mortality. We also present data onpolymorph isozymc variation betwccn wild fish from the stocks. The overview indicate that itmay be nccessary to include a number of traits to differentiate between stocks.
When can Fokker-Planck Equation describe anomalous or chaotic transport?

description: The Fokker-Planck Equation, applied to transport processes in fusion plasmas, can model several anomalous features, including uphill transport, scaling of confinement time with system size, and convective propagation of externally induced perturbations. It can be justified for generic particle transport provided that there is enough randomness in the Hamiltonian describing the dynamics. Then, except for 1 degree-of-freedom, the two transport coefficients are largely independent. Depending on the statistics of interest, the same dynamical system may be found diffusive or dominated by its Lévy flights.

description: We derive the two-loop evolution equation of the B-meson light-cone distribution amplitude which is the last missing element for the next-to-next-to-leading logarithmic resummation of QCD corrections to B decays in QCD factorization. We argue that the evolution kernel to all orders in perturbation theory can be written as a logarithm of the generator of special conformal transformations times the cusp anomalous dimension, up to a scheme-dependent overall constant. Up to this constant term, the evolution kernel to a given order in perturbation theory can be obtained from the calculation of special conformal anomaly at one order less.
