MAP-based multifunctional organocatalysts for asymmetric aza- and generic Morita–Baylis–Hillman reactions
Creators: name: Eliseenko, Sviatoslav Sergeevich
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: MAP-based trifunctional organocatalysts, containing a phosphine Lewis base, amino Brønsted base, and phenol or N-tosyl Brønsted acid, have demonstrated highly proficient catalysis of asymmetric aza-MBH reactions with an acid additive. The phosphine nucleophile (Lewis base) initiates the aza-MBH reaction by addition to an activated alkene (e.g. MVK). The Brønsted base, activated by the acid additive, in conjunction with the Brønsted acid, promotes the subsequent aldol and proton-transfer elimination steps by H-bonding interactions to provide high rate and enantioselectivity. However, the reaction scope of this catalysis is limited to aza-MBH and not amenable to generic MBH reactions. In order to improve the proficiency and expand the substrate scope, new Brønsted acid motifs, such as substituted phenol, N-tosyl and pyrrole groups, were incorporated into the MAP-structure for testing in aza-MBH and generic MBH reactions. Change of Brønsted acidity in the phenol- and N-tosyl-containing catalysts did not improve on catalytic proficiency while pyrrole-containing catalysts provided the improvement in enantioselectivity in generic MBH reactions.

description: Graphene nanostructures that support surface plasmons have been utilized to create a variety of dynamically tunable light modulators, motivated by theoretical predictions of the potential for unity absorption in resonantly-excited monolayer graphene sheets. Until now, the generally low efficiencies of tunable resonant graphene absorbers have been limited by the mismatch between free-space photons and graphene plasmons. Here, we develop nanophotonic structures that overcome this mismatch and demonstrate electronically tunable perfect absorption achieved with patterned graphenes covering less than 10% of the surface. Experimental measurements reveal 96.9% absorption in the graphene plasmonic nanostructure at 1,389 cm$^{-1}$, with an on/off modulation efficiency of 95.9% in reflection. An analytic effective surface admittance model elucidates the origin of perfect absorption, which is design for critical coupling between free-space modes and the graphene plasmonic nanostructures.

description: Persistent memory provides high-performance data persistence at main memory. Memory writes need to be performed in strict order to satisfy storage consistency requirements and enable correct recovery from system crashes. Unfortunately, adhering to such a strict order significantly degrades system performance and persistent memory endurance. This paper introduces a new mechanism, Loose-Ordering Consistency (LOC), that satisfies the ordering requirements at significantly lower performance and endurance loss. LOC consists of two key techniques. First, Eager Commit eliminates the need to perform a persistent commit record write within a transaction. We do so by ensuring that we can determine the status of all committed transactions during recovery by storing necessary metadata information statically with blocks of data written to memory. Second, Speculative Persistence relaxes the write ordering between transactions by allowing writes to be speculatively written to persistent memory. A speculative write is made visible to software only after its associated transaction commits. To enable this, our mechanism supports the tracking of committed transaction ID and multi-versioning in the CPU cache. Our evaluations show that LOC reduces the average performance overhead of memory persistence from 66.9% to 34.9% and the memory write traffic overhead from 17.1% to 3.4% on a variety of workloads.

description: The recent realization of two-dimensional (2D) synthetic spin-orbit (SO) coupling opens a broad avenue to study novel topological states for ultracold atoms. Here, we propose a new scheme to realize exotic chiral Fulde-Ferrell superfluid for ultracold fermions, with a generic theory being shown that the topology of superfluid pairing phases can be determined from the normal states. The main findings are two fold. First, a semimetal is driven by a new type of 2D SO coupling whose realization is even simpler than the recent experiment, and can be tuned into massive Dirac fermion phases with or without inversion symmetry. Without inversion symmetry the superfluid phase with nonzero pairing momentum is favored under an attractive interaction. Furthermore, we show a fundamental theorem that the topology of a 2D chiral superfluid can be uniquely determined from the unpaired normal states, with which the topological chiral Fulde-Ferrell superfluid with a broad topological region is predicted for the present system. This generic theorem is also useful for condensed matter physics and material science in search for new topological superconductors.

Transboundary haze pollution in the ASEAN region: an assessment of the adquacy of the legal and policy framework in Indonesia
Creators: name: Nurhidayah, Laely
Publisher: name: Macquarie University
Year: 2022

description: Transboundary haze pollution is one of the major ongoing problems in the ASEAN region. This haze pollution is the result of land/forest fires, and mostly originates in Indonesia. In addition to a long dry season, human activities such as the clearing of forests and land for plantations and agriculture, particularly in peatland areas, are a major cause of these fires. The impacts of these fires are significant and include damage to biodiversity, people’s health and the region’s economy, and contribution to global climate change. It is clear that haze pollution has an impact locally, nationally, regionally and internationally. Thus, while transboundary haze pollution is regarded as an international or regional problem, and there are already international and regional legal mechanisms in place to address the issue, it is argued that transboundary pollution is often more effectively addressed through domestic law. The challenge in addressing and enforcing transboundary haze-pollution control lies in the implementation and enforcement of law at the domestic level. Therefore, the legal frameworks in Indonesia for addressing land/forest fires are examined in this thesis. The main aim is to examine the adequacy of existing legal and policy frameworks in Indonesia in addressing transboundary haze pollution. This examination includes institutional arrangements, community-based fire management, and the issue of REDD+ and its implication for forest ires reduction. This research fills a gap in the literature on the current legal and policy framework in Indonesia. It argues that a well-structured integrated legal framework is crucial in addressing land/forest fires. It finds that the existing legal framework in Indonesia is inadequate to address land/forest fires. A new legislation must be enacted to specifically address the issue. However, land/forest fires are a complex problem cutting across many interests, sectors, communities, nations and regions. Therefore, no single solution will work to address this issue. Addressing transboundary haze pollution requires cooperation at the international, regional, national and local levels. Thus, it is proposed that, in addressing transboundary haze pollution, a synergetic and integrated approach is required, with coherence between international, regional, national and local frameworks. Further, it is argued that the best way to address land/forest fires at the national level is to improve all relevant measures, including the legal and institutional framework, public participation and law enforcement.

description: We perform a linearized local stability analysis for short-wavelength perturbations of a circular Couette flow with the radial temperature gradient. Axisymmetric and nonaxisymmetric perturbations are considered and both the thermal diffusivity and the kinematic viscosity of the fluid are taken into account. The effect of the asymmetry of the heating both on the centrifugally unstable flows and on the onset of the instabilities of the centrifugally stable flows, including the flow with the Keplerian shear profile, is thoroughly investigated. It is found that the inward temperature gradient destabilizes the Rayleigh stable flow either via Hopf bifurcation if the liquid is a very good heat conductor or via steady state bifurcation if viscosity prevails over the thermal conductance.

description: The determination of the CP nature of the Higgs coupling to top quarks is addressed in this paper, using $t{\bar t} h$ events produced in $\sqrt{s} = 13$ TeV proton-proton collisions at the LHC. Dileptonic final states are employed, with two oppositely charged leptons and four jets, corresponding to the decays $t\rightarrow bW^+ \rightarrow b \ell^+ν_\ell$, $\bar{t}\rightarrow \bar{b}W^- \rightarrow \bar{b} \ell^-\barν_\ell$ and $h\rightarrow b\bar{b}$. Pure scalar ($h=H$), pure pseudo-scalar ($h=A$) and CP-violating Higgs boson signal events, generated with MadGraph5_aMC@NLO, are fully reconstructed through a kinematic fit. We furthermore generate samples that have both a CP-even and a CP-odd component in the $t \bar t h$ coupling in order to probe the ratio of the two components. New angular distributions of the decay products, as well as CP angular asymmetries, are explored in order to separate the scalar from the pseudo-scalar components of the Higgs boson and reduce the contribution from the dominant irreducible background, $t{\bar t}b{\bar b}$. Significant differences between the angular distributions and asymmetries are observed, even after the full kinematic fit reconstruction of the events, allowing to define the best observables for a global fit of the Higgs couplings parameters.

description: Coherent Raman microscopy provide label-free imaging by interrogating the intrinsic vibration of biomolecules. Nevertheless, trade-off between high chemical-specificity and high imaging-speed currently exists in transition from spectroscopy to spectroscopic imaging when capturing dynamics in complex living systems. Here, we present a novel concept in dual-comb scheme to substantially beat this trade-off and facilitate high-resolution broadband coherent anti-Stokes Raman spectroscopic imaging based on down-converted, automatically varying delay-time in spectral focusing excitation. A rapid measurement of vibrational microspectroscopy on sub-microsecond scale over a spectral span ~700 cm-1 with solid signal-to-noise ratio provides access to well-resolved molecular signatures within the fingerprint region. We demonstrate this high-performance spectroscopic imaging of spatially inhomogeneous distributions of chemical substances as well as the carotenoids accumulation in plant cells. This technique offers an unprecedented route for broadband CARS imaging with hundreds of kHz frame rate using available 1-GHz oscillators.

description: The iron-based high temperature superconductors exhibit a rich phase diagram reflecting a complex interplay between spin, lattice, and orbital degrees of freedom [1-4]. The nematic state observed in many of these compounds epitomizes this complexity, by entangling a real-space anisotropy in the spin fluctuation spectrum with ferro-orbital order and an orthorhombic lattice distortion [5-7]. A more subtle and much less explored facet of the interplay between these degrees of freedom arises from the sizable spin-orbit coupling present in these systems, which translates anisotropies in real space into anisotropies in spin space. Here, we present a new technique enabling nuclear magnetic resonance under precise tunable strain control, which reveals that upon application of a tetragonal symmetry-breaking strain field, the magnetic fluctuation spectrum in the paramagnetic phase of BaFe$_{2}$As$_{2}$ also acquires an anisotropic response in spin-space. Our results unveil a hitherto uncharted internal spin structure of the nematic order parameter, indicating that similar to liquid crystals, electronic nematic materials may offer a novel route to magneto-mechanical control.

We give several examples of Reidemeister pairs derived from racks, quandles, rack and quandle cocycles, and central extensions of groups. We prove that our construction includes all rack and quandle cohomology (framed) link invariants, as well as the Eisermann invariant of knots. We construct a class of Reidemeister pairs which constitute a lifting of the Eisermann invariant, and show through an example that this class is strictly stronger than the Eisermann invariant itself.

description: In this article, maleic anhydride (MA) was used to graft-modify chitosan (CS) to obtain maleic anhydride-modified chitosan (MCS). Composite films with different ratios were prepared by melt blending-extrusion pelletizing-blown film using Poly (butylene adipate-co-terephthalate) (PBAT) as the substrate and CS or MCS as the filler. These films can be utilized in a variety of ways, such as food packaging, agricultural mulching film, and more. The composite films were characterized and tested by a Fourier transform infrared (FTIR) spectrometer, thermogravimetric (TG) analysis, differential scanning calorimetry (DSC), scanning electron microscope (SEM), and electronic universal testing machine, and the effects of different fillers and filler contents on the properties of the composite films were investigated. The results showed that the thermal stability of the composite films decreased slightly with the increase in filler ratio, the melt crystallization temperature increased and then decreased, and the tensile strength and elongation at break of the composite films decreased. Compared with unmodified CS, MCS had better dispersion and compatibility when blended with PBAT, and the interaction between MCS and PBAT was greater than that of CS. The optimal filler amount of MCS was 6% for the combination of film material cost and performance considerations.

Self-assembly of biomaterials and bioimaging using novel peptides

description: Protein immobilisation on solid matrices commonly relies on non-specific adsorption or the reaction between chemical groups within proteins and those on the matrix surface. In both cases, proteins attach to the surfaces in random orientations that may cause a reduction or loss of biological activity. Some peptides are capable of directing the immobilisation and orientation of proteins on solid surfaces without impeding protein function. They can recognise selectively and bind to a diverse range of inorganic substrates, for example, metals, materials containing carbon and polymers. In this thesis I present a robust and versatile bioconjugation system that circumvents conventional chemical methods. This technology is based on a unique peptide linker sequence that displays high affinity towards materials that contain silica. The linker sequence can be fused directly to the sequence of a protein of interest using genetic engineering techniques and produced in Escherichia coli. The resulting recombinant fusion protein (Linker-Protein) exhibits strong affinity to a range of materials that contain silica, including synthetic silica and zeolites. Several applications of this technology are presented in this thesis. The filamentous fungus Trichoderma reesei was tested as an alternative host to achieve higher yields and extracellular production of a linker-enzyme complex. However, the linker and several derivatives were rapidly degraded by T. reesei proteinases and further modification of the sequence is required by a directed evolution technique such as phage display. In a further application, the linker was incorporated into Streptococcus Protein G, an antibody-binding protein. The resulting Linker-Protein G (LPG) was able to direct the attachment of antibodies onto silica-coated magnetic particles. The biofunctionalised particles were used for the antibody-mediated binding and recovery of different cell types for rapid, simple visualisation and identification by microscopy. The application of LPG was extended further by the incorporation of luminescent lanthanide chelates. The Luminescence-Activating LPG (LA-LPG) was shown to impart strong luminescence to antibodies within seconds and represents a novel indirect detection reagent for time-gated luminescence bioimaging.

For the $D$-dimensional hydrogenic and oscillator-like systems, the wavefunctions of the corresponding bound states are controlled by the Laguerre ($\mathcal{L}_{m}^{(α)}(x)$) and Gegenbauer ($\mathcal{C}^{(α)}_{m}(x)$) polynomials in both position and momentum spaces, where the parameter $α$ linearly depends on $D$. In this work we study the asymptotic behavior as $α\to \infty$ of the associated entropy-like integral functionals of these two families of hypergeometric polynomials.

description: The work "La puerta del Vino" is characterized by Andalusian folk music, the PhrygianArabic mode (which influences partly the melody) and Habanera rhythm. In the ,,La puerta del Vino“ moves above the ostinato bass a melodic upper voice, which is partly expatriated, partly amplified by fifths or parallel chords and is characteristic in the change of duols and triplets. The Eastin Habanera rhythm can be found in two forms: • on the notes "of - as" (bars 1 - 41, bar 66 until the end) • on the notes "b - f" (bars 44 - 56).

description: Monogamy relations characterize the distributions of entanglement in multipartite systems. We investigate monogamy relations related to the concurrence $C$ and the entanglement of formation $E$. We present new entanglement monogamy relations satisfied by the $α$-th power of concurrence for all $α\geq2$, and the $α$-th power of the entanglement of formation for all $α\geq\sqrt{2}$. These monogamy relations are shown to be tighter than the existing ones.

description: The emission geometries, e.g. the emission region height, the beam shape, and radius-to-frequency mapping, are important predictions of pulsar radiation model. The multi-band radio observations carry such valuable information. In this paper, we study two bright pulsars, (PSRs B0329+54 and B1642-03) and observe them in high frequency (2.5 GHz, 5 GHz, and 8 GHz). The newly acquired data together with historical archive provide an atlas of multi-frequency profiles spanning from 100 MHz to 10 GHz. We study the frequency evolution of pulse profiles and the radiation regions with the these data. We firstly fit the pulse profiles with Gaussian functions to determine the phase of each component, and then calculate the radiation altitudes of different emission components and the radiation regions. We find that the inverse Compton scattering (ICS) model can reproduce the radiation geometry of these two pulsars. But for PSR B0329+54 the radiation can be generated in either annular gap (AG) or core gap (CG), while the radiation of PSR B1642-03 can only be generated in the CG. This difference is caused by the inclination angle and the impact angle of these two pulsars. The relation of beaming angle (the angle between the radiation direction and the magnetic axis) and the radiation altitudes versus frequency is also presented by modelling the beam-frequency evolution in the ICS model. The multi-band pulse profiles of these two pulsars can be described well by the ICS model combined with the CG and AG.

description: We compute the fermion spin distribution in the vortical fluid created in off-central high-energy heavy-ion collisions. We employ the event-by-event (3+1)D viscous hydrodynamic model. The spin polarization density is proportional to the local fluid vorticity in quantum kinetic theory. As a result of strong collectivity, the spatial distribution of the local vorticity on the freeze-out hyper-surface strongly correlates to the rapidity and azimuthal angle distribution of fermion spins. We investigate the sensitivity of the local polarization to the initial fluid velocity in the hydrodynamic model and compute the global polarization of Λ hyperons by the AMPT model. The energy dependence of the global polarization agrees with the STAR data.

description: The majority-vote model with noise was studied on the eleven Archimedean lattices by the Monte-Carlo method and the finite-size scaling. The critical noises and the critical exponents were obtained with unprecedented precision. Contrary to some previous reports, we confirmed that the majority-vote model on the Archimedean lattices belongs to the two-dimensional Ising universality class. It was shown that very precise determination of the critical noise is required to obtain proper values of the critical exponents.

Modelling exposure at default without using conversion factors

description: Banks accredited by their regulator to use the Advanced Internal Ratings Based (A-IRB) approach are required to provide their own estimates for calculating their minimum credit capital; these estimates rely on statistical and analytical models to predict Probability of Default (PD), Loss Given Default (LGD) and Exposure at Default (EAD). This thesis focusses on estimating EAD for banks granting revolving loans to large corporates and leverages the Global Credit Data (GCD) database. This thesis briefly discusses why risk management, particularly credit risk management, is important for banks and we survey the existing EAD modelling literature which to date has had less focus than PD and LGD modelling. Our prosed methodology models both loan balance at default (EAD) and changes in loan limit at default as random variables, modelling their joint dynamics via a two stage model– the first stage estimates the probability that limits decrease while the second stage estimates EAD conditional on changing limits. To the best of our knowledge, our approach is the first to estimate EAD and changes in loan limit directly for large corporate revolving facilities using the GCD database. Our model suggests that the key drivers of EAD include: limit; balance; utilisation; risk rating; and time to maturity. We also find evidence that banks actively manage limits in the lead up to default, and that these changes in limits have substantial effects on the outcomes of realised EAD.

description: This paper introduces a biparametric family of Lyapunov functions for a non-linear mathematical model based on the FitzHugh-Nagumo equations able to reproduce some main features of the X-ray bursting behaviour exhibited by the microquasar GRS 1915+105. These functions are useful to investigate the properties of equilibrium points and allow us to demonstrate a theorem on the global stability. The transition between bursting and stable behaviour is also analyzed.

description: Cognitive competencies of young children and structural and cultural familycharacteristics: developments and relations?

In this paper three questions are answered: 1) are there developments in the languageand math performance of young children; 2) are there developments in anumber of family characteristics (parental educational level, ethnicity, home language,proficiency level in Dutch, and reading behavior); and 3) are there relationsbetween the children’s competencies and their parents’ characteristics? Data fromthree waves of the PRIMA cohort study (1996, 1998 and 2000) were analyzed withone-level and multilevel techniques. The sample included a total of 24,130 pupilsat 688 primary schools. The results showed there to be just one development, namelya slight rise in language performance between 1996 and 1998.

description: The purpose of this document is to define a service infrastructure (referred as “platform”) providing the basis for the platform-specific specifications of the FP6-511678 integrated project ORCHESTRA (Open Architecture and Spatial Data Infrastructure for Risk Management), information models and services. As integral part of an ORCHESTRA Implementation Specification (OIS), it describes the technological choices of the service infrastructure and the operational issues of the infrastructure and thus enables the mapping of the ORCHESTRA Architecture (OA) to the selected platform.
 The focus of this document is the selection and description of relevant technologies. This corresponds to the technology viewpoint of the ORCHESTRA Reference Model. The mapping of the OA to the technologies described here is carried out in the respective implementation specifications and corresponds to the engineering viewpoint, whereas the selection of a programming language and the mapping definition rules is also part of the platform specification.
