Studies toward total syntheses of drimane type antifeedants from thujone
Creators: name: Gao, Zhenyong
Publisher: name: University of British Columbia

description: This thesis concerns studies directed towards a total synthesis of the drimane type dialdehyde 90 from thujone 42. The naturally occurring drimane dialdehydes have potent antifeedant activity. Development of a versatile synthesis of the drimane type dialdehydes from thujone was the main objective of this research. The decalone 80 was considered an efficient intermediate leading to the drimane dialdehydes. Much work was devoted to develop syntheses of such C7-decalones from thujone 47. The previously known enone 48, obtained in an efficient manner from thujone 42, is subjected to reduction via catalytic or Birch reduction to afford, in quantitative yield, the cis -fused ketone 62. Deoxygenation of the ketone 62 by Wolff-Kishner reduction afforded 22 in excellent yield. Detailed studies had shown that ozone selectively reacted at the activated tertiary carbon of the isopropyl side chain in molecules such as 22. Thus, the tricyclic alkane 22 was converted to the tertiary alcohol 21 by ozonation. The alcohol 22 was then elaborated to the key intermediate 80 via cyclopropane ring opening, free radical rearrangement and ozonation. The stereochemistry of the various products 62, 72, 73 and 80 with respect to the A/B fusion was established through correlation with the absolute structure and stereochemistry of the diketone 66 the latter being one of the ozonation products of ketone 62. Diketone 66 was subjected to X-ray diffraction analysis. The drimane skeleton was then constructed via formylation of 80 to 81 and the latter converted to 82, via reaction with phenylselenyl chloride followed by oxidative elimination of the resultant product. Conjugate addition of cyanide to the unsaturated keto-aldehyde 82 afforded 81. The latter was converted into the unsaturated aldehyde 85 via reduction of its (n-butylthio)methylene derivative, followed by borohydride reduction and mild hydrolysis. Protection of the aldehyde group in 85 gave 86 and the nitrile group in the latter was then reduced to give 88. The latter was then hydrolyzed to the drimane dialdehyde 90. The synthesis of 90 was accomplished in sixteen steps with an overall yield of 4% from thujone 47, thereby indicating that the individual steps in the sequence proceed in excellent yield. The biological activity of compound 90 will be evaluated. Approaches towards a total synthesis of the natural drimane polygodial 1 are also shown. [See Thesis for Diagram]

description: Context. The high number of super-Earth and Earth-like planets in the habitable zone (HZ) detected around M-dwarf stars in the last years has revealed these stellar objects to be the key for planetary radial velocity (RV) searches. Aims. Using the HARPS-N spectrograph within The HArps-n red Dwarf Exoplanet Survey (HADES) we reach the precision needed to detect small planets with a few Earth masses using the RV technique. Methods. We obtained 138 HARPS-N RV measurements between 2013 May and 2020 September of GJ 720 A, classified as an M0.5V star located at a distance of 15.56 pc. To characterize the stellar variability and to discern the periodic variation due to the Keplerian signals from those related to stellar activity, the HARPS-N spectroscopic activity indicators and the simultaneous photometric observations were analyzed. The combined analysis of HARPS-N RVs and activity indicators let us to address the nature of the periodic signals. The final model and the orbital planetary parameters were obtained by fitting simultaneously the stellar variability and the Keplerian signal using a Gaussian process regression and following a Bayesian criterion. Results. The HARPS-N RV periodic signals around 40 d and 100 d have counterparts at the same frequencies in HARPS-N activity indicators and photometric light curves. Then we attribute these periodicities to stellar activity the former period being likely associated with the stellar rotation. GJ 720 A shows the most significant signal at 19.466$\pm$0.005 d with no counterparts in any stellar activity indices. We hence ascribe this RV signal, having a semiamplitude of 4.72$\pm$0.27 m/s , to the presence of a sub-Neptune mass planet. The planet GJ 720 Ab has a minimum mass of 13.64$\pm$0.79 M$_{\oplus}$, it is in circular orbit at 0.119$\pm$0.002 AU from its parent star, and lies inside the inner boundary of the HZ around its parent star.

description: The analysis of images (of obtained in various ranges of the lengths of waves) of luminous objects in the Universe by means of a method of multilevel dynamic contrasting led author to the conclusions: a) the structures of all observable galaxies represents a complicated constructions which have the tendency to self-similarity and made of separate (basic) blocks, which are a coaxially tubular structures and a cartwheel-like structures; b) the majority of observable objects in the Universe are luminous butt-ends of almost invisible (of almost completely transparent) of filamentary formations which structures are seen only near to their luminous butt-ends; c) the result of analysis of images of cosmic objects show the structure of many pairs of cooperating galaxies point to opportunity of their formation at butt-ends generated in a place of break of the similar filament; d) the interacting galaxies (M 81 and M 82) show they are butt-ends of sawed off of two branches of a treelike filament and their interaction is coming out through this filament; e) as our Universe is in dynamics the processes of formation of stars, galaxies and their congestions can go presently by means of a fracturing of filaments with a corresponding diameters and of the time for their such formation is necessary much less, than along existing standard model.

description: Using the Karl G. Jansky Very Large Array (VLA), we have conducted a survey for 22 GHz, 6_{1,6}-5_{2,3} H2O masers toward the Serpens South region. The masers were also observed with the Very Long Baseline Array (VLBA) following the VLA detections. We detect for the first time H2O masers in the Serpens South region that are found to be associated to three Class 0-Class I objects, including the two brightest protostars in the Serpens South cluster, known as CARMA-6 and CARMA-7. We also detect H2O masers associated to a source with no outflow or jet features. We suggest that this source is most probably a background AGB star projected in the direction of Serpens South. The spatial distribution of the emission spots suggest that the masers in the three Class 0-Class I objects emerge very close to the protostars and are likely excited in shocks driven by the interaction between a protostellar jet and the circumstellar material. Based on the comparison of the distributions of bolometric luminosity of sources hosting 22 GHz H2O masers and 162 YSOs covered by our observations, we identify a limit of L_Bol ~ 10 L_Sun for a source to host water masers. However, the maser emission shows strong variability in both intensity and velocity spread, and therefore masers associated to lower-luminosity sources may have been missed by our observations. We also report 11 new sources with radio continuum emission at 22 GHz.

Towards Rigorous Interpretations: a Formalisation of Feature Attribution

description: Feature attribution is often loosely presented as the process of selecting a subset of relevant features as a rationale of a prediction. Task-dependent by nature, precise definitions of "relevance" encountered in the literature are however not always consistent. This lack of clarity stems from the fact that we usually do not have access to any notion of ground-truth attribution and from a more general debate on what good interpretations are. In this paper we propose to formalise feature selection/attribution based on the concept of relaxed functional dependence. In particular, we extend our notions to the instance-wise setting and derive necessary properties for candidate selection solutions, while leaving room for task-dependence. By computing ground-truth attributions on synthetic datasets, we evaluate many state-of-the-art attribution methods and show that, even when optimised, some fail to verify the proposed properties and provide wrong solutions.

description: The process of reconstruction of attosecond beating by interference of two-photon transitions (RABBITT) can become resonant with a discrete atomic level either in the intermediate or the final continuous states. Experimental observations of the former [Phys. Rev. Lett. 104, 103003 (2010)] or latter [Nat. Commun. 7, 10566 (2016)] cases revealed modification of only those parts of the photoelectron spectrum that overlapped directly with the resonance. In the lithium atom and other members of the alkali metal family, the valence shell $ns\to np$ transition to the intermediate RABBITT state affects the whole photoelectron spectrum in the final state. The strong additional resonant channel modifies entirely the ionization dynamics and opens direct access to the resonant phase of the two-photon transitions which is common for various single and multiple electron ionization processes. Elucidation of this phase has wider implications for strongly resonant laser-matter interaction.

description: We report new detailed surface U, B, V, R, and I photometry of 81 stellar structures in the disk of the barred galaxy NGC 3367. The images show many different structures indicating that star formation is going on in the most part of the disk. NGC 3367 is known to have a very high concentration of molecular gas distribution in the central regions of the galaxy and bipolar synchrotron emission from the nucleus with two lobes (at 6 kpc) forming a triple structure similar to a radio galaxy. We have determined the U, B, V, R, and I magnitudes and U - B, B - V, U - V, and V - I colors for the central region (nucleus), a region which includes supernovae 2003 AA, and 79 star associations throughout NGC 3367. Estimation of ages of star associations is very difficult due to several factors, among them: filling factor, metallicity, spatial distribution of each structure and the fact that we estimated the magnitudes with a circular aperture of 16 pixels in diameter, equivalent to $6''.8\sim1.4$ kpc. However, if the colors derived for NGC 3367 were similar to the colors expected of star clusters with theoretical evolutionary star tracks developed for the LMC and had a similar metallicity, NGC 3367 show 51 percent of the observed structures with age type SWB I (few tens of Myrs), with seven sources outside the bright surface brightness visible disk of NGC 3367.

description: We present a method to study the penumbral fine structure using data obtained by the spectropolarimeter onboard HINODE. For the first time, the penumbral filaments can be considered as resolved in spectropolarimetric measurements. This enables us to use inversion codes with only one-component model atmospheres, and thus assign the obtained stratifications of plasma parameters directly to the penumbral fine structure. This approach is applied to the limb-side part of the penumbra in active region NOAA 10923. The preliminary results show a clear dependence of the plasma parameters on continuum intensity in the inner penumbra, i.e. weaker and horizontal magnetic field along with increased line-of-sight velocity are found in the low layers of the bright filaments. The results in the mid penumbra are ambiguous and future analyses are necessary to unveil the magnetic field structure and other plasma parameters there.

description: We made a narrowband NB973 (bandwidth of 200A at 9755A) imaging of the Subaru Deep Field (SDF) and found two z=7 Lyman alpha emitter (LAE) candidates down to NB973=24.9. Carrying out deep follow-up spectroscopy, we identified one of them as a real z=6.96 LAE. This has shown that galaxy formation was in progress just 750 Myr after the Big Bang. Meanwhile, the Lyman alpha line luminosity function of LAE is known to decline from z=5.7 to 6.6 in the SDF. L* at z=6.6 is 40-60% of that at z=5.7. We also confirm that the number density of z=7 LAE is only 17% of the density at z=6.6 comparing the latest SDF LAE samples. This series of significant decreases in LAE density with increasing redshift can be the result of galaxy evolution during these epochs. However, using the UV continuum luminosity functions of LAEs, those of Lyman break galaxies, and a LAE evolution model based on the hierarchical clustering, we find that galaxy evolution alone cannot explain all the decrease in density. This extra density deficit can be interpreted as the attenuation of the Lyman alpha photons from LAEs due to a rapid evolution of neutral hydrogen fraction during the ongoing cosmic reionization at z~6.6-7.

We suggest possible extensions of the 't Hooft-Nobbenhuis symmetry, in particular, its complexification till duality symmetry and discuss the compatible implementation on gravity. We propose to use the discrete time-reflection transform to formulate a framework in which one can eliminate the huge contributions of vacuum energy into the effective cosmological constant and suggest that the breaking of time--reflection symmetry could be responsible for a small observable value of this constant.

Rare Decay Modes of Quarter BPS Dyons

description: The degeneracy of quarter BPS dyons in N=4 supersymmetric string theories is known to jump across walls of marginal stability on which a quarter BPS dyon can decay into a pair of half BPS dyons. We show that as long as the electric and magnetic charges of the original dyon are primitive elements of the charge lattice, the subspaces of the moduli space on which a quarter BPS dyon becomes marginally unstable against decay into a pair of quarter BPS dyons or a half BPS dyon and a quarter BPS dyon are of codimension two or more. As a result any pair of generic points in the moduli space can be connected by a path avoiding these subspaces and there is no jump in the spectrum associated with these subspaces.

description: We investigated the electronic response of the quasi-two-dimensional spin gap compound La4Ru2O10 using optical spectroscopy. We observed drastic changes in the optical spectra as the temperature decreased, resulting in anisotropy in the electronic structure of the spin-singlet ground state. Using the orbital-dependent hopping analysis, we found that orbital ordering plays a crucial role in forming the spin gap state in the non-one-dimensional material.

description: Despite their great potential in communication and sensing applications, printed leaky-wave antennas have rarely been reported at mm-wave frequencies. In this paper, tapered leaky-wave antennas operating at 80 GHz are designed, fabricated and experimentally characterized. While most continuous leaky-wave antennas use subwavelength strips or other comparably small elements, in this work, the surface impedance is discretized very coarsely using only three square patches per period. With this architecture, a wide range of surface reactance can be achieved while maintaining a minimum feature size of the metallic pattern that is feasible for printed circuit fabrication. As the analytical solution for the bandstructure of sinusoidally modulated reactance surfaces is inaccurate for coarse discretization, we find it using full-wave simulation. In order to control side lobes effectively, we use a tapered aperture illumination according to the Taylor one-parameter distribution. A comprehensive experimental demonstration is presented, including near-field and far-field measurements. Therewith, we verify the designed aperture illumination and we reveal the origin of spurious far-field features. Side lobes are effectively suppressed and spurious radiation is reduced to -18 dB compared to the main lobe.

description: The dynamics of quasicrystals is characterized by the existence of phason excitations in addition to the usual phonon modes. In order to investigate their interplay on an elementary level we resort to various one-dimensional model systems. The main observables are the static, the incoherent, and the coherent structure factor, which are extracted from molecular dynamics simulations. For the validation of the algorithms, results for the harmonic periodic chain are presented. We then study the Fibonacci chain with harmonic and anharmonic interaction potentials. In the dynamic Fibonacci chain neighboring atoms interact by double-well potentials allowing for phason flips. The difference between the structure factors of the dynamic and the harmonic Fibonacci chain lies in the temperature dependence of the phonon line width. If a bias is introduced in the well depth, dispersionless optic phonon bands split off.

description: Kurt Gödels ontologischer Gottesbeweis, in dem er die notwendige Existenz Gottes über die maximale Menge der positiven Eigenschaften beweist, wurde 1970 veröffentlicht. In den Jahrzehnten zuvor wurden seine Unvollständigkeitssätze (1931), seine Beweisskizze über die Vereinbarkeit der ZF-Mengenlehre mit dem Auswahlaxiom und der allgemeinen Kontinuumshypothese (1939), Arbeiten zur Erweiterung der Mengenlehre, sowie metamathematische Texte und Vorträge zur Grundlegung der Mathematik veröffentlicht. In der vorliegenden Arbeit wird der Zusammenhang dieser unterschiedlichen Arbeiten Gödels beschrieben und seine Auswirkungen auf die Grundlegung der Mathematik diskutiert. Dabei wird insbesondere Gödels Forderung nach neuen Begriffen, seine philosophische Anschauung zur mathematischen Intuition und Konzeptbildung und der Aufbau seines philosophischen, metamathematischen Programms auf der absoluten Unendlichkeit (in Anlehnung an Leibniz’ Monadologie und seine Urmonade), herausgestellt. In diesem Zusammenhang wird ein neuer Mengenbegriff etabliert, der als Analogie zur Allklasse und zum Prinzip der Unerreichbarkeit von V als Grund-Axiom die Verbindung zwischen den hier diskutierten verschieden Gebieten und Gödels ontologischem Gottesbeweis darstellt, in dem das Maximum der positiven Eigenschaften über einen offenen, homogenen Mengenbegriff erreicht und so die notwendige Existenz Gottes bewiesen wird.

Alkynyl and isocyanobiphenyls : new thermotropic liquid crystals
Creators: name: Bailey, Austin Lou
Publisher: name: University of British Columbia
Year: 2010

description: The presence of mesomorphism in 4-n-alkyl-4'-isocyanobiphenyls 4 and 4-n-alkyl-4'-alkynylbiphenyls 5 was investigated, based on the liquid-crystallinity of the cyanobiphenyls 2 (R = n-alkyl). Compound 4 (R = n-butyl) is non-mesomorphic, whereas 4 (R = n-pentyl) is a virtual liquid crystal melting at 34-35°C and supercooling to a nematic phase at 30°C, and 4 (R = n-hexyI) is a nematic liquid crystal from 9 to 19°C. Compounds of structure 5 (R = n-pentyl, X = Si(CH₃)₃, H, CH₃, CI) are not liquid crystals. The corresponding bromo- and iodoalkynes (5, R = n-pentyl, X = Br, I) are liquid crystals with mesomorphic ranges of 88-108°C and 110-119°C, respectively. [See Thesis for Diagram]

description: A new nonlinear integral equation (NLIE) describing the thermodynamics of the Heisenberg spin chain is derived based on the t-W relation of the quantum transfer matrices. The free energy of the system in a magnetic field is thus obtained by solving the NLIE. This method can be generalized to other lattice quantum integrable models. Taking the SU(3)-invariant quantum spin chain as an example, we construct the corresponding NLIEs and compute the free energy. The present results coincide exactly with those obtained via other methods previously.

description: Οι ‘Φυσικές Επιστήμες’ μέσα στο Πρόγραμμα Σπουδών για την Προσχολική Εκπαίδευση αναγνωρίζουν πως οι μικροί μαθητές οδηγούνται σταδιακά στη συστηματοποίηση της σκέψης, χρησιμοποιούν τη φαντασία και τη δημιουργικότητά τους, ώστε να ανακαλύψουν τη νέα γνώση, να κατανοήσουν τον κόσμο και τα φαινόμενα και να λαμβάνουν όλα τα απαραίτητα εφόδια για να αντεπεξέλθουν στις σύγχρονες απαιτήσεις της κοινωνίας ως «επιστημονικά εγγράμματοι πολίτες». Σκοπός της παρούσας έρευνας είναι να διερευνηθεί αν τα παιδιά της προσχολικής εκπαίδευσης μπορούν να κατανοήσουν τις φυσικές επιστήμες μέσα από τις τεχνικές της Δραματικής Τέχνης στην Εκπαίδευση. Παρουσιάζεται μία έρευνα δράσης που πραγματοποιήθηκε σε παιδιά ηλικίας τεσσάρων και πέντε ετών του Σώματος Ελληνικού Οδηγισμού που εδρεύει στο Δήμο Τρίπολης, όπου διεξήχθησαν οι δώδεκα θεατροπαιδαγωγικές παρεμβάσεις. Η ποιοτική έρευνα θεωρήθηκε η καταλληλότερη ερευνητική προσέγγιση με στρατηγική την έρευνα δράσης για την παρούσα. Πραγματοποιήθηκε σκόπιμη δειγματοληψία όπου αποτελούνταν από δεκατρία παιδιά προσχολικής εκπαίδευσης. Τα ερευνητικά δεδομένα συλλέχθηκαν από το ημερολόγιο της ερευνήτριας, παρατηρήσεις της κριτικής φίλης και τεκμήρια των συμμετεχόντων με οπτικοακουστικό υλικό όπου αναλύθηκαν ποιοτικά. Καταλήγοντας συμπερασματικά και απαντώντας στα ερευνητικά ερωτήματα ότι μέσω των τεχνικών της δραματικής τέχνης τα παιδιά προσχολικής αγωγής είναι σε θέση να κατανοήσουν τις έννοιες των φυσικών επιστημών ειδικότερα τον κύκλο του νερού, την εναλλαγή νύχτας και μέρας και τους μαγνήτες. Επιπρόσθετα ανέπτυξαν δεξιότητες όπως η συνεργασία, η φαντασία και η σωματική τους έκφραση.

description: Σε ποιόν βαθμό η πράξη της δημιουργίας σημαίνει εγγύτητα του Δημιουργού στα έργα Του; Ποιόν ‘παράδεισο’ εγκατέλειψε ο άνθρωπος με την ‘παράβαση’; Ποιά είναι η ‘πρώτη ύλη’ των όντων; Τί σημαίνει για τον άνθρωπο η χωροχρονική συγκρότηση και αλλοίωση ως αντίθεση στην απλότητα της θείας φύσης; Τί σημαίνει η προέλευση των όντων ‘εκ του μηδενός’; Πώς σχετίζεται ο χωροχρόνος με την θεία βούληση; Ποιό είναι το περιεχόμενο της συντέλειας των καιρών; Τί σημαίνει το ‘κατ’ εικόνα’; Ποιά είναι η σχέση της ψυχής με την Δημιουργία; Πώς συμφωνεί με την τριαδικότητα ο μονοθεϊσμός και ποιά πραγματική αξία έχει για την θεία και την ανθρώπινη ύπαρξη η τριαδικότητα; Θίγοντας τα σχετικά ζητήματα η έρευνα αυτή της κοσμολογίας του Γρηγορίου Νύσσης και του Μάιστερ Έκκαρτ, αναδεικνύει ταυτόχρονα την σημασία θεωρητικών διαφορών και ομοιοτήτων μεταξύ των δύο σπουδαίων Μυστικών της χριστιανοσύνης.
description: To what extent creation implies the Creator’s nearness to His works? What kind of ‘paradise’ man abandoned with the ‘transgression’? Which is the ‘prime matter’ of beings? What is the meaning for man of the spatiotemporal structure and change as opposed to the simplicity of the divine nature? What does the origin of beings ‘out of nothing’ mean? How is the divine will related to space and time? What is the meaning of the end of times? What does creation of man ‘according to the image’ mean? How is the soul related to Creation? How does Monotheism agree with trinitarianism and what is the real value of trinitarianism for the existence of God and man? Raising questions related with these issues, the current study of the cosmology of Gregory of Nyssa and Meister Eckhart highlights also the importance of theoretical similarities and differences between the two great Christian Mystics.

description: We investigate the parametric amplification of the zero-point fluctuations in the spin modes of a two-component Bose-Einstein condensate, triggered by the dynamical evolution of the condensate density. We first make use of a Thomas-Fermi approximation to develop a tractable theoretical model of the quantum dynamics of the Bogoliubov excitations in a harmonically trapped condensate with a time-dependent trapping frequency. The predictions of this model are then compared to an ab-initio numerical study of the correlation functions of density and spin fluctuations for general spatially inhomogeneous configurations. Results are shown for the two cases of expanding and oscillating condensates: while the quantum excitation of spin modes remains weak and relatively featureless in the case of an expanding condensate, clear and experimentally promising signatures of particle creation are anticipated for the oscillating case under suitable resonance conditions between the density and the spin modes.

description: In this paper we investigate several properties of the full signal-idler-pump mode quantum state generated by a triply resonant non-degenerate Optical Parametric Oscillator operating above threshold, with an injected wave on the signal and idler modes in order to lock the phase diffusion process. We determine and discuss the spectral purity of this state, which turns out not to be always equal to 1 even though the three interacting modes have been taken into account at the quantum level. We have seen that the purity is essentially dependent on the weak intensity of the injected light and on an asymmetry of the synchronization. We then derive the expression of its total three-mode Glauber P-function, and calculate the joint signal-idler photon number probability distribution and investigate their dependence on the injection.

description: Compared to the conventional metasurface design, machine learning-based methods have recently created an inspiring platform for an inverse realization of the metasurfaces. Here, we have used the Deep Neural Network (DNN) for the generation of desired output unit cell structures in an ultra-wide working frequency band for both TE and TM polarized waves. To automatically generate metasurfaces in a wide range of working frequencies from 4 to 45 GHz, we deliberately design an 8 ring-shaped pattern in such a way that the unit-cells generated in the dataset can produce single or multiple notches in the desired working frequency band. Compared to the general approach, whereby the final metasurface structure may be formed by any randomly distributed "0" and "1", we propose here a restricted output structure. By restricting the output, the number of calculations will be reduced and the learning speed will be increased. Moreover, we have shown that the accuracy of the network reaches 91\%. Obtaining the final unit cell directly without any time-consuming optimization algorithms for both TE and TM polarized waves, and high average accuracy, promises an effective strategy for the metasurface design; thus, the designer is required only to focus on the design goal.

description: A seminal gedankenexperiment by Laughlin describes the charge transport in quantum Hall systems via the pumping of flux. Here, we propose an optical scheme which probes and manipulates quantum Hall systems in a similar way: When light containing orbital angular momentum interacts with electronic Landau levels, it acts as a flux pump which radially moves the electrons through the sample. We investigate this effect for a graphene system with Corbino geometry, and calculate the radial current in the absence of any electric potential bias. Remarkably, the current is robust against the disorder which is consistent with the lattice symmetry, and in the weak excitation limit, the current shows a power-law scaling with intensity characterized by the novel exponent 2/3.
