description: The programming language MATLAB is widespread in the field of scientific computing. In some cases it may be reasonable to use external software, which is to be embedded into or invoked from MATLAB code. Interfacing Java code from MATLAB is directly available. The MATLAB compiler (MCC) and the MATLAB executables (MEX) enable the coupling to C/C++ code. If the desired software system is highly hybrid and distributed, that means many different pieces of code speak to each other possibly over network, the approach can be cost-intensive. The Component Template Library (CTL) is a middleware which supports the coupling of C/C++, Fortran, Java or Python code. In this paper we present how to couple CTL additionally with MATLAB.

description: We use the methods of topological quantum chemistry to explore the topology of phonons on time-reversal symmetric crystals with the structure of the planar honeycomb (layer group $p6/mmm$). This approach is not tied to a particular model of atomic vibrations, but is applied to the most general dynamical matrix constrained only by the symmetries of the system. We show that four distinct fragile topological phonon phases are generically possible. Truncating the dynamical matrix to third nearest neighbors yields a model that realizes the different phonon topologies, characterized by the existence of phononic edge and corner modes and by Wilson loops with winding numbers one and two. Fitting the dynamical matrix to the DFT phonon bands shows that graphene is not very far from a topologically nontrivial phonon phase.

Kant and Secular Transcendentalism
Creators: name: Phemister, Alexander Ewen
Publisher: name: The Australian National University
Year: 2007

description: This writing argues that some embedded moral and religious linkages in Kant’s metaphysical thought have been unobserved in much recent philosophical commentary, something we may attribute to the de-emphasis of metaphysics within significant parts of the contemporary academic world, combined with a lack of awareness of the religious milieu within which he worked. Paradoxically in the light of this, and based on the religious content I find in the first Critique and elsewhere, I explore what I perceive to be Kant’s attempt to steer traditional religious doctrines and practice into a secular, individualised, scientifically congruent, completely independent and universally acceptable format. From this, I develop the idea that an appreciation of these efforts to reform earlier theological thought allows for a more complete and coherent interpretation of critical philosophy than has previously been available, with application, for example, to a heightened understanding of the employment of the idea of things in themselves. The primary notion involved in this amended reading is the primacy Kant gives to practical reason...
Forced Migrant Women Confront Institutional Constraints in a Community College

subject: Women immigrants--Education

description: This dissertation examines how the formal schooling trajectories of forced migrant women from Africa and the Middle East are shaped by the ongoing confrontation of the women with the policies and practices of the community college they attend. It is based on ethnographic fieldwork done at a community college in the largest metropolitan area in the otherwise predominantly rural state of Maine. This work is motivated by an interest in the validity of the rhetoric of community college as the vehicle for upward social mobility for marginalized populations. The students in the study are constructed as various types of minorities: linguistic, racial, religious, national, depending on the bureaucratic, social or schooling context. Because of the ideology of equal opportunity, often the only documentation by the community college of minority status is their language status that is recognized in the standardized entrance exam. Racial and national origin information is voluntary and commonly left blank on official forms, but, along with religion, are made meaningful both in and outside of the classroom through interactions with white peers and teachers. Forced migrant students experience this construction of otherness, and react through the formation of social support networks made up exclusively of forced migrants where they teach each other ways of adaption and resistance. Because of the conditions that led to their flight, forced migrants have survived traumatic situations, face language barriers and may have interrupted formal schooling, as well as retain familial obligations around the globe that present unique challenges. The community college does not fully recognize these challenges, and maintains a narrow standard that is upheld through teaching practices and the use of standardized exams, which serve to marginalize forced migrant students. This marginalization translates into low graduation rates for forced migrants, effectively blocking any upward social mobility to be gained from the community college.

description: In this research, hydroxyl terminated poly butadiene (HTPB) was modified by alkylferrocene based silane derivatives via hydrosilylation reaction. The chemical structures of the new synthesized compounds was confirmed with FT-IR, 1H NMR and 13C NMR spectroscopy as well as CHN analysis. Thermal characteristics of final polymers were studied by thermogravimetric analysis (TGA). In addition, viscosity and glass transition temperature (Tg) of the new polymers were determined. The results indicate that modifications of the HTPB was carried out successfully. The new alkylferrocene modified HTPB can be considerate as good candidates for burning rate accelerator catalyst in preparation of composite gas generator.

Force and Conductance Spectroscopy of Single Molecule Junctions

Year: 2012
Subjects: Physics
Chemistry

description: Investigation of mechanical properties of single molecule junctions is crucial to develop an understanding and enable control of single molecular junctions. This work presents an experimental and analytical approach that enables the statistical evaluation of force and simultaneous conductance data of metallic atomic point contacts and molecular junctions. A conductive atomic force microscope based break junction technique is developed to form single molecular junctions and collect conductance and force data simultaneously. Improvements of the optical components have been achieved through the use of a super luminescent diode, enabling tremendous increases in force resolution. An experimental procedure to collect data for various molecular junctions has been developed and includes deposition, calibration, and analysis methods. For the statistical analysis of force, novel approaches based on two dimensional histograms and a direct force identification method are presented. The two dimensional method allows for an unbiased evaluation of force events that are identified using corresponding conductance signatures. This is not always possible however, and in these situations, the force based identification of junction rearrangement events is an attractive alternative method. This combined experimental and analytical approach is then applied to three studies: First, the impact of molecular backbones to the mechanical behavior of single molecule junctions is investigated and it is found that junctions formed with identical linkers but different backbone structure result in junctions with varying breaking forces. All molecules used show a clear molecular signature and force data can be evaluated using the 2D method. Second, the effects of the linker group used to attach molecules to gold electrodes are investigated. A study of four alkane molecules with different linkers finds a drastic difference in the evolution of donor acceptor and covalently bonded molecules respectively. In fact, the covalent bond is found to significantly distort the metal electrode rearrangement such that junction rearrangement events can no longer be identified with a clean and well defined conductance signature. For this case, the force based identification process is used. Third, results for break junction measurements with different metals are presented. It is found that silver and palladium junctions rupture with forces different from those of gold contacts. In the case of silver experiments in ambient conditions, we can also identify oxygen impurities in the silver contact formation process, leading to force and conductance measurements of silver-oxygen structures. For the future, this work provides an experimental and analytical foundation that will enable insights into single molecule systems not previously accessible.
An Infrared Picosecond Optical Parametric Oscillator for Polymer Ablation

Publisher: name: The Australian National University
Year: 2004
Subjects: Honours thesis

description: The development of an infrared optical parametric oscillator based on Magnesium Oxide doped Periodically Poled Lithium Niobate (MgO:PPLN) is described. The OPO is synchronously pumped by a high average power, picosecond, Nd:YVO4 mode-locked laser operating at 1064nm. The OPO generates signal and idler radiation at wavelengths centered at 1550nm and 3.4µm respectively. The OPO is singly resonant at the the signal wavelength. The multiple QPM grating periods and temperature control imposed upon the PPLN crystal aﬀord a broad tuning range of the OPO output. The signal is tunable from 1450-1700nm, corresponding to an idler tuning range of 2.8-4.0µm. Pumping the OPO at 10W yielded 1.5W of extracted idler power at 3.3µm. The OPO is intended as a light source for pulsed laser ablation of polymers. Previous demonstrations of pulsed laser polymer ablation used a Free Electron Laser as the light source. The OPO was successfully used to evaporate polymers, although the physical mechanism is uncertain. Further development of this, or similar devices oﬀers a ﬂexible, and more accessible alternative to a FEL for polymer ablation.

description: Tuberculosis (TB) is a prehistoric infection and major etiologic agent of TB, Mycobacterium tuberculosis, which is considered to have advanced from an early progenitor species found in Eastern Africa. By the 1800s, there were approximately 800 to 1000 fatality case reports per 100,000 people in Europe and North America. This research suggests an In-silico study to identify potential inhibitory compounds for the target Mycobacterial copper transport protein (Mctb). ADME-based virtual screening, molecular docking, and molecular dynamics simulations were conducted to find promising compounds to modulate the function of the target protein. Four chemical compounds, namely Anti-MCT1, Anti-MCT2, Anti-MCT3 and Anti-MCT4 out of 1500 small molecules from the Diverse-lib of MTiOpenScreen were observed to completely satisfy Lipinski rule of five and Veber’s rule. Further, significantly steady interactions with the MctB target protein were observed. Docking experiments have presented 9 compounds with less than −9.0 kcal/mol free binding energies and further MD simulation eventually gave 4 compounds having potential interactions and affinity with target protein and favorable binding energy ranging from −9.2 to −9.3 kcal/mol. We may propose these compounds as an effective candidate to reduce the growth of M. tuberculosis and may also assist present a novel therapeutic approach for Tuberculosis. In vivo and In vitro validation would be needed to proceed further in this direction. Communicated by Ramaswamy H. Sarma

description: Modelling and simulation are essential tools for concept evaluation and for predicting the performance of a hybrid energy system, since prototyping and testing each candidate design for such a complex system would almost always be prohibitively cumbersome, expensive and time consuming. To meet the modelling and simulation objectives, the various components of the system (sources, storage, loads, and converters) need to be characterised and modelled in a tractable way. The tuning of the models to reflect the actual system components is a key milestone in this process and requires reliable and comprehensive experimental data. Furthermore, environmental conditions such as ambient temperature may have a significant impact on the performance, which has to be taken into account. The complexity of hybrid energy systems and their dependence on embedded control software increases the difficulty in predicting interactions among the various components and subsystems. A modelling environment that can model not only the components but also control algorithms (such as Matlab/Simulink, Homer etc.) is therefore advantageous. Effective diagnosis of faults in an installed system also presents a challenge, because of the interactions between the components and the control system. Modelling may play an important role in diagnosis of the operating components. For example, running an electrolyser model and comparing actual electrolyser operating variables with those obtained from the model may help to diagnose a fault in the real electrolyser. This thesis focuses on modelling the principal components of hybrid solar energy systems that include energy storage in the form of hydrogen: a large photovoltaic array subject to manufacturer’s variability and temperature inhomogeneity; two types of electrolyser as commonly found in hydrogen energy systems; a metal-hydride hydrogen storage tank; a fuel cell. Attention is given here to building physics-based component models with minimum empiricism and to critically analysing the state of the art in modelling such components. The models have been realised in Simulink, so that they are mutually compatible and can be linked into a whole of system model. All the models were validated against experimental data and performed at least as well as models found in the literature. The thesis is based on six papers, four already published and two submitted.

description: Monkeypox virus (MPV) is closely related to the smallpox virus, and previous data from Africa suggest that the smallpox vaccine (VARV) is at least 85% effective in preventing MPV. No multi-epitope vaccine has yet been developed to prevent MPV infection. In this work, we used in silico structural biology and advanced immunoinformatic strategies to design a multi-epitope subunit vaccine against MPV infection. The designed vaccine sequence is adjuvanted with CpG-ODN and includes HTL/CTL epitopes for similar proteins between vaccinia virus (VACV) that induced T-cell production in vaccinated volunteers and the first draft sequence of the MPV genome associated with the suspected outbreak in several countries, May 2022. In addition, the specific binding of the modified vaccine and the immune Toll-like receptor 9 (TLR9) was estimated by molecular interaction studies. Strong interaction in the binding groove as well as good docking scores confirmed the stringency of the modified vaccine. The stability of the interaction was confirmed by a classical molecular dynamics simulation and normal mode analysis. Then, the immune simulation also indicated the ability of this vaccine to induce an effective immune response against MPV. Codon optimization and in silico cloning of the vaccine into the pET-28a (+) vector also showed its expression potential in the E. coli K12 system. The promising data obtained from the various in silico studies indicate that this vaccine is effective against MPV. However, additional in vitro and in vivo studies are still needed to confirm its efficacy. Communicated by Ramaswamy H. Sarma

description: Let $G_M$ be one of the complex Lie groups $O_M$ and $Sp_M$. The irreducible finite-dimensional representations of the group $G_M$ are labeled by partitions $μ$ satisfying certain extra conditions. Let $U$ be the representation of $G_M$ corresponding to $μ$. Regard the direct product $G_N\times G_M$ as a subgroup of $G_{N+M}$. Let $V$ be the irreducible representation of $G_{N+M}$ corresponding to a partition $λ$. Consider the vector space $W=Hom_{G_M}(U,V)$. It comes with a natural action of the group $G_N$. Let $n$ be sum of parts of $λ$ less the sum of parts of $μ$. For any choice of a standard Young tableau of skew shape $λ/μ$, we realize $W$ as a subspace in the tensor product of $n$ copies of the defining $N$-dimensional representation of $G_N$. This subspace is determined as the image of a certain linear operator $F(M)$ in the tensor product, given by an explicit formula. When M=0 and $W=V$ is an irreducible representation of $G_N$, we recover the classical realization of $V$ as a subspace in the space of all traceless tensors. Then the operator F(0) can be regarded as the analogue for $G_N$ of the Young symmetrizer, corresponding to the chosen standard tableau of shape $λ$. Even in the special case M=0, our formula for the operator $F(M)$ is new. Our results are applications of representation theory of the twisted Yangian, corresponding to $G_N$. In particular, $F(M)$ is an intertwining operator between two representations of the twisted Yangian in the $n$-fold tensor product.

description: The width of a resonance in a nearly integrable system, i.e. in a non-integrable system where chaotic motion is still not prominent, can tell us how a perturbation parameter is driving the system away from integrability. Although the tool that we are presenting here can be used is quite generic and can be used in a variety of systems, our particular interest lies in binary compact object systems known as extreme mass ratio inspirals (EMRIs). In an EMRI a lighter compact object, like a black hole or a neutron star, inspirals into a supermassive black hole due to gravitational radiation reaction. During this inspiral the lighter object crosses resonances, which are still not very well modeled. Measuring the width of resonances in EMRI models allows us to estimate the importance of each perturbation parameter able to drive the system away from resonances and decide whether its impact should be included in EMRI waveform modeling or not. To tackle this issue in our study we show first that recurrence quantifiers of orbits carry imprints of resonant behavior, regardless of the system's dimensionality. As a next step, we apply a long short-term memory machine learning architecture to automate the resonance detection procedure. Our analysis is developed on a simple standard map and gradually we extend it to more complicated systems until finally we employ it in a generic deformed Kerr spacetime known in the literature as the Johannsen-Psaltis spacetime.

description: A novel realization of the classical SU(2) algebra is introduced for the Dirac relativistic hydrogen atom defining a set of operators that, besides, allow the factorization of the problem. An extra phase is needed as a new variable in order to define the algebra. We take advantage of the operators to solve the Dirac equation using algebraic methods. To acomplish this, a similar path to the one used in the angular momentum case is employed; hence, the radial eigenfuntions calculated comprise non unitary representations of the algebra. One of the interesting properties of such non unitary representations is that they are not labeled by integer nor by half-integer numbers as happens in the usual angular momentum representation.

description: Thousands of New York City Renters have been foreclosed upon since the beginning of foreclosure crises in 2006. While, some of the foreclosed renters have managed to remain in their apartments after the foreclosure, some of foreclosed renters have been asked by new owners to evict their homes. A significant number of evicted renters have been helped by Legal Aid and Legal Services in NYC. This Thesis is an attempt to learn more about the Socio-Economic Impacts of foreclosure crises on Evicted Renters, who have been helped by Legal Aid and Legal Society in NYC. Has foreclosure eviction disrupted their lives? How has eviction impacted their employment? Does it increase poverty? Attorneys at NYC's Legal Aid and Services were interviewed to explain their experiences and perceptions about the socio-economic impacts of foreclosure on evicted renters. Moreover, using data from census 2000 and Furman center dataset, demographic, socio-economic, and foreclosure maps are created to find correlations among them. Regression is also run to examine some of the trends that came out of the interviews. Finally recommendations are made to help different levels of governments to craft better policies toward both preventing eviction as well as providing helps for the already evicted tenants.

description: Using different sources of information to support automated extracting of relations between biomedical concepts contributes to the development of our understanding of biological systems. The primary comprehensive source of these relations is biomedical literature. Several relation extraction approaches have been proposed to identify relations between concepts in biomedical literature, namely, using neural networks algorithms. The use of multichannel architectures composed of multiple data representations, as in deep neural networks, is leading to state-of-the-art results. The right combination of data representations can eventually lead us to even higher evaluation scores in relation extraction tasks. Thus, biomedical ontologies play a fundamental role by providing semantic and ancestry information about an entity. The incorporation of biomedical ontologies has already been proved to enhance previous state-of-the-art results.

description: This article updates the 2008 UK guidelines for the medical and laboratory screening of sperm, egg and embryo donors. This was achieved by a working group composed of representatives from: the Association of Biomedical Andrologists, the Association of Clinical Embryologists, the British Andrology Society and the British Fertility Society, with subsequent review and commentary from their respective memberships. Information and guidance on core facts which should be made evident to all parties involved in donation are provided. Changes with regard to transmissible disease screening include: (i) extended guidance regarding history taking, risk factors and deferral periods; (ii) recommended quarantine period for donors screened by Nucleic Acid Testing (NAT) and serology is now 3 months; (iii) recommended quarantine period for donors screened by serology alone is legally required to be 6 months; (iv) if donor oocytes, or embryos created with donor oocytes, are cryopreserved then the quarantine period should be observed as best practice. We further recommend that consideration be given to HPV vaccination of women who outside of insemination may not be exposed to HPV. For heritable diseases, the discussion and assessment of genetic risk have been fundamentally reviewed in light of technological advances. After review of scientific evidence, it has also been deemed acceptable for men to donate sperm up to their 46th birthday.

description: This work identifies a simple pre-training mechanism that leads to representations exhibiting better continual and transfer learning. This mechanism -- the repeated resetting of weights in the last layer, which we nickname "zapping" -- was originally designed for a meta-continual-learning procedure, yet we show it is surprisingly applicable in many settings beyond both meta-learning and continual learning. In our experiments, we wish to transfer a pre-trained image classifier to a new set of classes, in a few shots. We show that our zapping procedure results in improved transfer accuracy and/or more rapid adaptation in both standard fine-tuning and continual learning settings, while being simple to implement and computationally efficient. In many cases, we achieve performance on par with state of the art meta-learning without needing the expensive higher-order gradients, by using a combination of zapping and sequential learning. An intuitive explanation for the effectiveness of this zapping procedure is that representations trained with repeated zapping learn features that are capable of rapidly adapting to newly initialized classifiers. Such an approach may be considered a computationally cheaper type of, or alternative to, meta-learning rapidly adaptable features with higher-order gradients. This adds to recent work on the usefulness of resetting neural network parameters during training, and invites further investigation of this mechanism.

description: We study the meaning of "adding a constant to a language" for any doctrine, and "adding an axiom to a theory" for a primary doctrine, by showing how these are actually two instances of the same construction. We prove their universal properties, and how these constructions are compatible with additional structure on the doctrine. Existence of Kleisli object for comonads in the 2-category of indexed poset is proved in order to build these constructions.

description: On the two-dimensional non-linear $Σ$-model describing a ferromagnet with Dzyaloshinskii-Moriya interaction, we build three families of exact static solutions depending on a single Cartesian variable. One of them describes a clockwise helix configuration, that characterizes the ground state of the system. A second one corresponds to a counterclockwise helix, representing an excited state. These two families of solutions are parameterized by a continuous parameter that depends on the magnetic field and the Dzyaloshinskii-Moriya coupling. Finally, the third family exists only for isolated values of the same parameter, corresponding to a discrete family of Viviani curves on the target sphere. The degeneracy of the resulting spectrum suggests that an approximate symmetry may emerge at specific values of the magnetic field, at which additional solutions could then exist.

Formation and Characterisation of Amorphous Gallium Nitride

description: For this study, wurtzite GaN was epitaxially grown on a Al2O3 substrate. Four samples were implanted with 4.7MeV Au ions to doses below and above the amorphisation threshold. These are characterised relative to an un-implanted as-grown sample. The extent of amorphisation within the ion-implanted material is characterised by comparing the results of rigorous analysis using the complementary techniques of X-Ray Diffraction (XRD), Rutherford Backscattering Spectrometry (RBS), Transmission Electron Microscopy (TEM) and Extended X-ray Absorption Fine Structure (EXAFS). XRD experiments highlight disordering of the GaN structure in the highest dose sample, characteristic of amorphisation. This is contrasted by results of TEM analysis which show uniformly distributed but randomly orientated GaN nanocrystals within an amorphous matrix, suggesting that the material is not completely amorphous. EXAFS analysis suggests an unusually high second nearest neighbour (NN) coordination number (CN) in the highest dose sample further indicating the presence of residual crystallinity within the ion-implanted material. The random orientation of the GaN nanocrystals within the otherwise amorphous matrix is consistent with ion-induced reconstruction and suggests the nanocrystals were formed after the matrix was rendered amorphous. TEM analysis also yields images of N2 gas bubbles, characteristic of ion-induced disordering of GaN, within the amorphous and nanocrystalline GaN material. The results of studies performed on other III-V semiconductors suggests that this would indicate the presence of Ga-Ga homopolar bonding however no direct evidence of this was found.

Searching for correlations in global environmental noise within the context of gravitational wave detection

honours thesis

description: The high sensitivity required of interferometric gravitational wave detectors is such that environmental noise becomes a very important consideration. Local environmental noise may be partially or wholly eliminated by cross-correlating data from two widely displaced detectors; such a strategy, however, will not be immune to environmental noise that is global in nature. Thus the characterisation of global environmental noise is of vital importance to the detection of gravitational waves. In this project the author will attempt to gain some understanding of physical environment noise, in particular whether it can be global as well as local in nature, by investigating the correlation of widely displaced physical environment monitoring stations. We found that, though there were no immediately significant correlations between the detectors, the unknown physical origin of the observed correlations would certainly be worthy of further research.

description: The safest and most effective sources of medications are natural and traditional medicines derived from plants and herbs. In Western India, various parts of the Dalbergia sissoo plant, which belongs to the Fabaceae family, have been traditionally used to treat different types of cancer by the local tribes. However, this claim has not been scientifically proven yet. Thus, the purpose of this study was to examine the antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity) and anticancer effects of different plant extracts from Dalbergia sissoo bark, root, and branch on six different cancer cell lines (K562, PC3, A431, A549, NCIH 460, and HEK 293 T) using in vitro cell viability and cytotoxicity assays. The study also involved in silico docking, MD simulation, and ADME studies of previously reported bioactive compounds from the same parts of the plant to confirm their bioactivity. The DPPH radical scavenging experiment findings showed that the methanol: water extract of the bark had a more significant antioxidant activity IC50 (45.63 ± 1.24 mg/mL). Furthermore, the extract prevented the growth of the A431, A549, and NCIH 460 cancer cell lines with the lowest IC50 values of 15.37, 29.09, and 17.02 g/mL, respectively, demonstrating remarkable anticancer potential. Molecular docking and dynamic simulation studies revealed that Prunetin, Tectorigenin, and Prunetin 4'-O-Galactoside show efficient binding to the EGFR binding domain. This study suggests that tested hits may have antioxidant and anticancer agents and can be considered for future applications in the pharma sector. Communicated by Ramaswamy H. Sarma
