Reaction selectivity and asymmetric synthesis in solid state organic photochemistry
Creators: name: Chen, Shuang
Publisher: name: University of British Columbia
Year: 2009

description: The Norrish/Yang type II photochemistry of four bicyclo[3.3.1]nonyl phenyl ketones was studied in solution and in the crystalline state. In both media, the bicyclic ketones without a-methyl substituents were found to be photochemically inert, while the cc-methyl substituted ones underwent Yang photocyclization to give endo-aryl cyclobutanols as predominant products. An unusual 1,4-hydroxybiradical disproportionation reaction was also observed during the photolysis of the α-methylated bicyclo[3.3.1]nonyl phenyl ketones, although it was a minor process (< 5%). By utilizing the ionic chiral auxiliary method, chiral ammonium carboxylate salts (7 in total) were formed between optically pure amines and the achiral bicyclo[3.3.1]nonyl phenyl ketone derivative containing a carboxylic acid substituent. Photolysis of these salts in the solid state afforded the cyclobutanol product with fair to excellent enantiomeric excesses (45% - 96%). A homologous series of spirobicyclo[3.3.1]nonyl ketones (4 in total) was synthesized and their Norrish/Yang type II photochemistry was investigated both in solution and in the solid state. These compounds were chosen for investigation because the conformation of the 1,4-biradicals formed by γ-hydrogen atom abstraction could be varied in a regular and incremental fashion by changing the size of the ketone-containing spiro ring. X-ray crystallographic analysis of these compounds provided detailed information about the geometric factors responsible for the partitioning of the intermediate 1,4-hydroxybiradicals among cleavage, cyclization, and reverse hydrogen transfer. Parameters governing the efficiency of the type II cleavage and Yang cyclization were established, respectively. The results indicate that while geometry does have a strong influence on the 1,4-hydroxybiradical partitioning among cyclization, cleavage and reverse hydrogen transfer, a full understanding of the results requires that the strain involved in forming the cyclization products be taken into account. The ionic chiral auxiliary approach for asymmetric induction was also investigated in a c/s-bicyclo[4.3.0]non-8-ylacetophenone system, which undergoes the Norrish type II photocleavage reaction to yield a simple chiral alkene — cis-3a, 4, 5, 6, 7, 7a-hexahydro-1H-indene. Irradiation of chiral salts (5 in total) in the crystalline state gave enantioselectivities ranging from poor to moderate (ee = 11% - 67%). Single crystal X-ray diffraction studies were performed on a number of these compounds, and on this basis, the structure-reactivity relationships involved were discussed.

description: We discuss a new phenomenon of turbulent thermal diffusion associated with turbulent transport of aerosols in the atmosphere and in laboratory experiments. The essence of this phenomenon is the appearance of a nondiffusive mean flux of particles in the direction of the mean heat flux, which results in the formation of large-scale inhomogeneities in the spatial distribution of aerosols that accumulate in regions of minimum mean temperature of the surrounding fluid. This effect of turbulent thermal diffusion was detected experimentally. In experiments turbulence was generated by two oscillating grids in two directions of the imposed vertical mean temperature gradient. We used Particle Image Velocimetry to determine the turbulent velocity field, and an Image Processing Technique based on an analysis of the intensity of Mie scattering to determine the spatial distribution of aerosols. Analysis of the intensity of laser light Mie scattering by aerosols showed that aerosols accumulate in the vicinity of the minimum mean temperature due to the effect of turbulent thermal diffusion. Geophysical applications of the obtained results are discussed.

description: (Abridged) We observed the X-ray bright E3 galaxy NGC 1600 and nearby group members with the Chandra X-ray Observatory ACIS S3. Unresolved emission dominates the observation; however, we resolved some emission into 71 sources, most of which are low-mass X-ray binaries (LMXBs) associated with NGC 1600. Twenty-one sources have L_X>2E39 ergs/s (0.3-10.0 keV; assuming they are at the distance of NGC 1600) marking them as ultraluminous X-ray point source (ULX) candidates; we expect only 11+/-2 are unrelated sources. NGC 1600 may have the largest number of ULX candidates in an early-type galaxy to date; however, cosmic variance in the number of background AGN cannot be ruled out. There are indications that there are also a large number of unresolved point sources. We propose that these are associated with globular clusters (GCs), and that NGC 1600 has a large GC specific frequency. The unresolved emission appears to have two gas components. We interpret the soft inner component (a~25", kT~1.5 keV) as the intragroup medium of the NGC 1600 group. The X-ray image shows several interesting structures, excess emission roughly cospatial with H$α$ and dust filaments, possible holes in the X-ray emission roughly coincident with radio lobes, excess emission to the northeast possibly indicating the center of the group potential, and a tail of X-ray emission from the group galaxy NGC 1603 probably due to ram-pressure stripping

description: Let A be a basic connected finite dimensional algebra over a field k and let Q be the ordinary quiver of A. To any presentation of A with Q and admissible relations, R. Martinez-Villa and J. A. de La Pena have associated a group called the fundamental group of this presentation. There may exist different presentations of A with non isomorphic fundamental groups. In this note, we show that if the field k has characteristic zero, if Q has no oriented cycles and if Q has no double bypasses then there exists a privileged presentation of A such that the fundamental group of any other presentation is the quotient of the fundamental group of this privileged presentation.

description: In many scientific settings there is a need for adaptive experimental design to guide the process of identifying regions of the search space that contain as many true positives as possible subject to a low rate of false discoveries (i.e. false alarms). Such regions of the search space could differ drastically from a predicted set that minimizes 0/1 error and accurate identification could require very different sampling strategies. Like active learning for binary classification, this experimental design cannot be optimally chosen a priori, but rather the data must be taken sequentially and adaptively. However, unlike classification with 0/1 error, collecting data adaptively to find a set with high true positive rate and low false discovery rate (FDR) is not as well understood. In this paper we provide the first provably sample efficient adaptive algorithm for this problem. Along the way we highlight connections between classification, combinatorial bandits, and FDR control making contributions to each.

description: We demonstrate and analyze how deploying non-classical intensity correlations obtained from a monolithic semiconductor quantum photon source can enhance classical target detection systems. This is demonstrated by examining the advantages offered by the utilization of the non-classical correlations in a correlation based target detection protocol. We experimentally demonstrate that under the same condition, the target contrast obtained from the protocol when non-classical correlations are utilized exhibits an improvement of up to 17.79dB over the best classical intensity correlation-based target detection protocol, under 29.69dB channel loss and excess noise 13.40dB stronger than the probe signal. We also assessed how the strong frequency correlations within the non-classical photon pairs can be used to further enhance this protocol.

description: In this study we define a three-step procedure to relate the self-decomposability of the stationary law of a generalized Ornstein-Uhlenbeck process to the law of the increments of such processes. Based on this procedure and the results of Qu et al. (2019), we derive the exact simulation, without numerical inversion, of the skeleton of a Variance Gamma, and of a symmetric Variance Gamma driven Ornstein-Uhlenbeck process. Extensive numerical experiments are reported to demonstrate the accuracy and efficiency of our algorithms. These results are instrumental to simulate the spot price dynamics in energy markets and to price Asian options and gas storages by Monte Carlo simulations in a framework similar to the one discussed in Cummins et al. (2017, 2018).

description: Attempts to apply Neural Networks (NN) to a wide range of research problems have been ubiquitous and plentiful in recent literature. Particularly, the use of deep NNs for understanding complex physical and chemical phenomena has opened a new niche of science where the analysis tools from Machine Learning (ML) are combined with the computational concepts of the natural sciences. Reports from this unification of ML have presented evidence that NNs can learn classical Hamiltonian mechanics. This application of NNs to classical physics and its results motivate the following question: Can NNs be endowed with inductive biases through observation as means to provide insights into quantum phenomena? In this work, this question is addressed by investigating possible approximations for reconstructing the Hamiltonian of a quantum system in an unsupervised manner by using only limited information obtained from the system's probability distribution.

Various fractal indices, characteristic of the signals emitted at the different structural failures of the test samples and which satisfy non-stationary distributions, have been determined. From the results obtained for these indices, related to the Hurst analysis, detrended fluctuation analysis, minimal cover analysis and to the boxcounting dimension analysis, it has been shown they can discriminate the different failure mechanisms and, therefore, they constitute their signature.

description: Incentive based stormwater management policies offer the prospect of reducing urban stormwater runoff while increasing developer profits. An incentive compatible Stormwater Banking Program (SBP) is presented that allows developers to build at higher residential densities in exchange for including low impact stormwater Best Management Practices (BMPs) in the development’s stormwater management infrastructure. Price endogeneity presents itself when the smaller residential lots created by building at a greater density sell for a lower price than the original, larger lots. Stormwater management authorities must be aware of this and the effects of the program participation fee structure in designing voluntary incentive based policies that meet runoff reduction objectives.

description: In the context of the GRAVITY+ upgrade, the adaptive optics (AO) systems of the GRAVITY interferometer are undergoing a major lifting. The current CILAS deformable mirrors (DM, 90 actuators) will be replaced by ALPAO kilo-DMs (43x43, 1432 actuators). On top of the already existing 9x9 Shack-Hartmann wavefront sensors (SH-WFS) for infrared (IR) natural guide star (NGS), new 40x40 SH-WFSs for visible (VIS) NGS will be deployed. Lasers will also be installed on the four units of the Very Large Telescope to provide a laser guide star (LGS) option with 30x30 SH-WFSs and with the choice to either use the 9x9 IR-WFSs or 2x2 VIS-WFSs for low order sensing. Thus, four modes will be available for the GRAVITY+ AO system (GPAO): IR-NGS, IR-LGS, VIS-NGS and VIS-LGS. To prepare the instrument commissioning and help the observers to plan their observations, a tool is needed to predict the performances of the different modes and for different observing conditions (NGS magnitude, science object magnitude, turbulence conditions...) We developed models based on a Mar{é}chal approximation to predict the Strehl ratio of the four GPAO modes in order to feed the already existing tool that simulates the GRAVITY performances. Waiting for commissioning data, our model was validated and calibrated using the TIPTOP toolbox, a Point Spread Function simulator based on the computation of Power Spectrum Densities. In this work, we present our models of the NGS modes of GPAO and their calibration with TIPTOP.

description: We develop a formalism for single molecule dynamic force spectroscopy to map the energy landscape of protein-protein complex ($P_1$$P_2$). The joint distribution $P(τ_1,τ_2)$ of unbinding lifetimes $τ_1$ and $τ_2$ measurable in a compression-tension cycle, which accounts for the internal relaxation dynamics of the proteins under tension, shows that the histogram of $τ_1$ is not Poissonian. The theory is applied to the forced unbinding of protein $P_1$, modeled as a wormlike chain, from $P_1$$P_2$. We propose a new class of experiments which can resolve the effect of internal protein dynamics on the unbinding lifetimes.

description: The critical properties for the transition to warm, asymmetric, non-homogeneous nuclear matter are analysed within a thermodynamical spinodal approach for a set of well calibrated equations of state. It is shown that even though different equations of state are constrained by the same experimental, theoretical and observational data, and the properties of symmetric nuclear matter are similar within the models, the properties of very asymmetric nuclear matter, such as the one found inside of neutron stars, differ a lot for various models. Some models predict larger transition densities to homogeneous matter for beta-equilibrated matter than for symmetric nuclear matter. Since one expects that such properties have a noticeable impact on the the evolution of either a supernova or neutron star merger, this different behavior should be understood in more detail.

A study of the structural and magnetic properties of some transition metal complexes of pyridine and pyrazine carboxylates
Creators: name: Stevens, Cecilia Leigh
Publisher: name: University of British Columbia
Year: 2009

description: In this work, a variety of transition-metal complexes incorporating anionic ligands with certain similar structural characteristics were synthesised and examined. The compounds were characterised by IR and UV/VIS/NIR spectroscopy, thermogravimetric analysis, elemental analysis, variable-temperature magnetic susceptibility, and, where possible, also by single-crystal X-ray analysis or X-ray powder diffraction. The neutral ligand precursors employed were 2,3-pyridine dicarboxylic acid (2,3-pydcH₂), 2,4- pyridine dicarboxylic acid (2,4-pydcH₂), 2,5-pyridine dicarboxylic acid (2,5-pydcH₂), pyrazine carboxylic acid (pyzcH), 2,5-pyrazine dicarboxylic acid (2,5-pyzdcH₂), and benzimidazole-2-carboxylic acid (bicH₂), all of which have a carboxylic acid group adjacent to a heteroaromatic ring nitrogen. The metal ions used were manganese (II), cobalt (II), nickel (II), copper (II), and cadmium (II). Both benchtop and hydrothermal preparations were performed. The isolated products include monometallic, polymetallic, and heterobimetallic coordination compounds. Magneto-structural correlations were performed for the various paramagnetic compounds prepared. The majority of the compounds were magnetically dilute or weakly antiferromagnetic. One polymetallic short-range ferromagnet was prepared (Cu(2,4-pydc)•0.5H₂O), one heterobimetallic coordination polymer proved to be ferromagnetic ([Cu(2,4-pydc)₂Mn(H₂O)4][sub x]), and one heterobimetallic species proved to have long-range ferrimagnetic ordering (Co(2,5-pydc)₂Mn-H₂O). Compounds incorporating ligated water were subjected to thermal dehydration, and the derivatives of lesser hydration were characterized and their magnetic activities compared to that of the parent compounds. In most cases, the dehydrated compounds were weakly antiferromagnetic, with slightly stronger exchange than the weakly antiferromagnetic or magnetically dilute parent compounds. Some showed no measurable change. Three showed an alteration in the type of magnetic coupling taking place: from weakly antiferromagnetic to ferromagnetic for [Cu(2,4-pydc)(H₂O) ₂][sub x] → Cu(2,4-pydc)-0.5H₂O , from ferromagnetic to weakly antiferromagnetic for [Cu(2,4-pydc)₂Mn(H₂O)₄][sub x] → Cu(2,4-pydc)₂Mn(H₂O), and from weakly antiferromagnetic to strongly ferrimagnetic for [Co(2,5-pydc)₂(H₂O)₂Mn(H₂O)₄][sub x] 4xH₂O → Co(2,5-pydc)₂Mn(H₂O).

description: We used a state contingent approach to give a detailed analysis of the uncertainty surrounding seed trait adoption. Our framework emphasizes the role of timing and information in farmers’ adoption decisions. The inherent embeddedness of seed traits results in timing restrictions and the inability of post-planting adjustments, this in turn results in farmers necessarily engaging in a game with nature. Two main types of traits we identify are supplementing traits and stabilizing traits – classification into each category is directly related on the mobility of the production factor the trait intends to substitute. Supplementing traits allow for acting after nature (i.e., ex post) while stabilizing traits are better modeled as acting before nature (i.e., ex ante). The type of trait results in different determinants of the farmers’ WTP function.

description: This article presents Expansion 22 of the ERIЯƎ Theory, demonstrating how particle masses and fundamental quantum properties can emerge from internal rotational coherence. By simulating particles as coherent geometric modes—spherical, toroidal, or floral—the model reproduces electron mass, neutrino structure, and the emergence of the Higgs field without empirical constants or tuning.

Using symbolic operators (EIRE and RIRE) and domain projections, the simulation yields nearly perfect agreement with experimental values, including for the W boson. The Higgs is shown to emerge as a scalar deviation (∆) in coherence modes, completing a unified geometric architecture of matter.

description: We revisit the issue of non-parametric gravitational lens reconstruction and present a new method to obtain the cluster mass distribution using strong lensing data without using any prior information on the underlying mass. The method relies on the decomposition of the lens plane into individual cells. We show how the problem in this approximation can be expressed as a system of linear equations for which a solution can be found. Moreover, we propose to include information about the null space. That is, make use of the pixels where we know there are no arcs above the sky noise. The only prior information is an estimation of the physical size of the sources. No priors on the luminosity of the cluster or shape of the halos are needed thus making the results very robust. In order to test the accuracy and bias of the method we make use of simulated strong lensing data. We find that the method reproduces accurately both the lens mass and source positions and provide error estimates.

description: The policies that regulate greenhouse gas emissions would provide a significant burden to emission industries as well as final consumers, which can lead to a strong influence on international trade flows of commodities. This study examines the impact of regulating greenhouse gas emissions on livestock trade flows using a commodity specific gravity model approach. This study finds that regulating greenhouse gas emissions has a negative effect on livestock trade flows from countries restricting greenhouse gas emissions to unrestricting countries, from restricting to restricting countries, and from unrestricting to restricting countries.

description: The thermochromic properties (color change with temperature) of n type doped SiC wafers of different polytypes (3C, 4H and 6H) have been investigated up to 500$^\circ$C under air. It was found that 3C-SiC color passes from bright yellow at room temperature to deep orangeat 500$^\circ$C leading to a color contrast ($Δ$E) as high as 64. The hexagonal polytypes undergo also a color change upon heating but far less pronounced, with $Δ$E values <20. All these semiconductors undergo band gap shrinkage upon heating which effect largely participated to the observed color change. This effect is very sensitive for 3C polytypesince its bandgap is already in the visible energy range at room temperature. The thermochromicity of 3C-SiC was found to be reversible thanks to its thermal stability and its resistance towards oxidation.

description: Universal quantum computing with continuous variables requires non-Gaussian resources, in addition to a Gaussian set of operations. A known resource enabling universal quantum computation is the cubic phase state, a non-Gaussian state whose experimental implementation has so far remained elusive. In this paper, we introduce two Gaussian conversion protocols that allow for the conversion of a non-Gaussian state that has been achieved experimentally, namely the trisqueezed state [Sandbo Changet al., Phys. Rev. X10, 011011 (2020)],to a cubic phase state. The first protocol is deterministic and it involves active (in-line) squeezing, achieving large fidelities that saturate the bound for deterministic Gaussian protocols. The second protocol is probabilistic and it involves an auxiliary squeezed state, thus removing the necessity of in-line squeezing but still maintaining significant success probabilities and fidelities even larger than for the deterministic case. The success of these protocols provides strong evidence for using trisqueezed states as resources for universal quantum computation.

description: The Alcubierre metric is a spacetime geometry where a massive particle inside a spacetime distortion, called warp bubble, is able to travel at velocities arbitrarily higher than the velocity of light, a feature known as the warp drive. This is a consequence of general relativity, which allows global superluminal velocities but restricts local speeds to subluminal ones as required by special relativity. In this work we solved the Einstein equations for the Alcubierre warp drive spacetime geometry considering the dust matter distribution as source, since the Alcubierre metric was not originally advanced as a solution of the Einstein equations, but as a spacetime geometry proposed without a source gravity field. We found out that all Einstein equations solutions of this geometry containing pressureless dust lead to vacuum solutions. We also concluded that these solutions connect the Alcubierre metric to the Burgers equation, which describes shock waves moving through an inviscid fluid. Our results also indicated that these shock waves behave as plane waves.

description: We present the results of CO(1-0) observations of the host galaxy of a Type I superluminous supernova (SLSN-I), SN2017egm, one of the closest SLSNe-I at z = 0.03063, by using the Atacama Large Millimeter/submillimeter Array. The molecular gas mass of the host galaxy is $M_{\rm gas} = (4.8 \pm 0.3) \times 10^9$ $M_{\odot}$, placing it on the sequence of normal star-forming galaxies in an $M_{\rm gas}$-star-formation rate (SFR) plane. The molecular hydrogen column density at the location of SN2017egm is higher than that of the Type II SN PTF10bgl, which is also located in the same host galaxy, and those of other Type II and Ia SNe located in different galaxies, suggesting that SLSNe-I have a preference for a dense molecular gas environment. On the other hand, the column density at the location of SN2017egm is comparable to those of Type Ibc SNe. The surface densities of molecular gas and the SFR at the location of SN2017egm are consistent with those of spatially resolved local star-forming galaxies and follow the Schmidt-Kennicutt relation. These facts suggest that SLSNe-I can occur in environments with the same star-formation mechanism as in normal star-forming galaxies.

description: The frequency-dependent scaling of the dispersive and dissipative parts of the alternating susceptibility is studied for spin glasses at criticality. An extension of the usual $ωt$-scaling is proposed. Simulational data from the three-dimensional Ising spin glass agree with this new scaling form and moreover reproduce well the scaling functions explicitly calculated for systems satisfying local scale-invariance. There is also a qualitative agreement with existing experimental data.

description: We propose a formula for the eigenvalue integral of the hermitian one matrix model with infinite well potential in terms of dressed twist fields of the su(2) level one WZW model. The expression holds for arbitrary matrix size n, and provides a suggestive interpretation for the monodromy properties of the matrix model correlators at finite n, as well as in the 1/n-expansion.

Synchrotron-based pore-network modeling of two-phase flow in Nubian Sandstone and implications for capillary trapping of carbon dioxide

description: Depleted oil fields in the Gulf of Suez (Egypt) can serve as geothermal reservoirs for power generation using a CO2-Plume Geothermal (CPG) system, while geologically sequestering CO2. This entails the injection of a substantial amount of CO2 into the highly permeable brine-saturated Nubian Sandstone. Numerical models of two-phase flow processes are indispensable for predicting the CO2-plume migration at a representative geological scale. Such models require reliable constitutive relationships, including relative permeability and capillary pressure curves. In this study, quasi-static pore-network modelling has been used to simulate the equilibrium positions of fluid-fluid interfaces, and thus determine the capillary pressure and relative permeability curves. Three-dimensional images with a voxel size of 0.65 micro m3 of a Nubian Sandstone rock sample have been obtained using Synchrotron Radiation X-ray Tomographic Microscopy. From the images, topological properties of pores/throats were constructed. Using a pore-network model, we performed a sequential primary drainage-main imbibition cycle of quasi-static invasion in order to quantify (1) the CO2 and brine relative permeability curves, (2) the effect of initial wetting-phase saturation (i.e. the saturation at the point of reversal from drainage to imbibition) on the residual-trapping potential, and (3) study the relative permeability-saturation hysteresis. The results improve our understanding of the potential magnitude of capillary trapping in Nubian Sandstone, essential for future field-scale simulations. Further, an initial basin-scale assessment of CO2 storage capacity, which incorporates capillary trapping, yields a range of 14-49 GtCO2 in Nubian Sandstone, Gulf of Suez Basin.
