description: Since its invention, holography has emerged as a powerful tool to fully reconstruct the wavefronts of light including all the fundamental properties (amplitude, phase, polarization, wave vector, and frequency). For exploring the full capability for information storage/display and enhancing the encryption security of metasurface holograms, smart multiplexing techniques together with suitable metasurface designs are highly demanded. Here, we integrate multiple polarization manipulation channels for various spatial phase profiles into a single birefringent vectorial hologram by completely avoiding unwanted cross-talk. Multiple independent target phase profiles with quantified phase relations that can process significantly different information in different polarization states are realized within a single metasurface. For our metasurface holograms, we demonstrate high fidelity, large efficiency, broadband operation, and a total of twelve polarization channels. Such multichannel polarization multiplexing can be used for dynamic vectorial holographic display and can provide triple protection for optical security. The concept is appealing for applications of arbitrary spin to angular momentum conversion and various phase modulation/beam shaping elements.

description: Hydrate plugging of hydrocarbon production conduits can cause large operational problems resulting in considerable economical losses. Modeling capabilities to predict hydrate plugging occurrences would help to improve facility design and operation in order to reduce the extent of such events. It would also contribute to a more effective and safer remediation process. This paper systematically describes different operational scenarios where hydrate plugging might occur and how a hydrate plug formation prediction tool would be beneficial. The current understanding of the mechanisms for hydrate formation, agglomeration and plugging of a pipeline are also presented. The results from this survey combined with the identified industrial needs are then used as a basis for the assessment of the capabilities of an existing hydrate plug formation model, called CSMHyK (The Colorado School of Mines Hydrate Kinetic Model). This has recently been implemented in the transient multiphase flow simulator OLGA as a separate module. Finally, examples using the current model in several operational scenarios are shown to illustrate some of its important capabilities. The results from these examples and the operational scenarios analysis are then used to discuss the future development needs of the CSMHyK model.
Towards a consistent understanding of the exotic nucleus $^{42}_{14}Si_{28}$

description: The issue of whether $^{42}_{14}Si_{28}$ is doubly magical or not has been a contentious one. Fridmann {\it et al.} (Nature 435 (2005) 922) through studies of two-proton knockout reaction $^{44}_{16}S_{28} \rightarrow ^{42}_{14}Si_{28}$, presented a strong empirical evidence in support of magicity and sphericity of $^{42}_{14}Si_{28}$. However in complete conflict with this, Bastin {\it et al.} (Phys. Rev. Lett. 99 (2007) 022503) gave equally strong empirical evidences, to show that the N = 28 magicity had completely collapsed, and that $^{42}_{14}Si_{28}$ was a well deformed nucleus. At present the popular consensus (Gade {\it et al.}, Phys. Rev. Lett. 122 (2019) 222501) strongly supports the latter one and discards the former one. Here, while we accept the latter experiment as being fine and good, through a careful study of an RMF model calculation, we show that actually the experimental results of Fridmann are also independently good and consistent. As per the Fridmann experiment, the sphericity and magicity of $^{42}_{14}Si_{28}$ is manifested only through proton number Z=14 being a strong magic number, while the neutron magic number N=28 disappears (or goes into hiding); and still this nucleus is spherical. This is a new and amazing property manifesting itself in this exotic nucleus $^{42}_{14}Si_{28}$. In this paper we provide a consistent understanding of this novel reality within a QCD based model. This model, which has been successful in explanation of the halo phenomenon in exotic nuclei, comes forward to provide the physical reason as to why the Fridmann experiment is correct. This QCD based model shows that it is tritons, as elementary entity making up $^{42}_{14}Si_{28}$, which then provides consistency to the above amazing conclusions arising from the Fridmann experiment.

description: Non-small cell lung cancer (NSCLC) accounts for 85% of lung cancer which is a leading cause of cancer death. Most patients (>80%) present with advanced NSCLC when curative surgery is no longer an option. Other conventional therapies, such as chemotherapy, radiotherapy and existing molecular targeted therapy have neither significantly extended the life span of most patients, nor improved their quality of life. This is not only because of the large tumor load in the advanced stage of NSCLC but its metastasis. This project devises a novel approach to shield the “magic bullet” and help it locate and kill targeted cancer cells.

description: Interactions between macromolecules play a crucial role in ribosome assembly that follows a highly coordinated process involving RNA folding and binding of ribosomal proteins (r-proteins). Although extensive studies have been carried out to understand macromolecular interactions in ribosomes, most of them are confined to either large or small ribosomal-subunit of few species. A comparative analysis of macromolecular interactions across different domains is still missing. We have analyzed the structural and physicochemical properties of protein-protein (PP), protein-RNA (PR) and RNA-RNA (RR) interfaces in small and large subunits of ribosomes, as well as in between the two subunits. Additionally, we have also developed Random Forest (RF) classifier to catalog the r-proteins. We find significant differences as well as similarities in macromolecular recognition sites between ribosomal assemblies of prokaryotes and eukaryotes. PR interfaces are substantially larger and have more ionic interactions than PP and RR interfaces in both prokaryotes and eukaryotes. PP, PR and RR interfaces in eukaryotes are well packed compared to those in prokaryotes. However, the packing density between the large and the small subunit interfaces in the entire assembly is strikingly low in both prokaryotes and eukaryotes, indicating the periodic association and dissociation of the two subunits during the translation. The structural and physicochemical properties of PR interfaces are used to predict the r-proteins in the assembly pathway into early, intermediate and late binders using RF classifier with an accuracy of 80%. The results provide new insights into the classification of r-proteins in the assembly pathway.

description: Trachylepis bayonii (Bocage, 1872)
 Material (two specimens): Two adult specimens (MHNCUP/REP 276–277, formerly UP-MHNFCP-018333 and UP-MHNFCP-040727; Fig. S40), collected from unknown locality, date unknown.
 Comments: Trachylepis bayonii is known from central and southwestern Angola, as well as Democratic Republic of the Congo, Kenya, and Tanzania (Marques et al. 2018). No specimens of T. bayonii were published by Ferreira. Bocage first described this species in 1872 and distinguished between two variations, A and B, from “Duque de Bragança” [=Kalandula], Malanje Province and from Huíla’s highlands, respectively (Bocage 1872; Marques et al. 2018). Variety B was later described as Mabuya bayoni huilensis by Laurent (1964).

description: One of the most fundamental and yet elusive collective phases of an interacting electron system is the quantum Wigner crystal (WC), an ordered array of electrons expected to form when the electrons' Coulomb repulsion energy eclipses their kinetic (Fermi) energy. In low-disorder, two-dimensional (2D) electron systems, the quantum WC is known to be favored at very low temperatures ($T$) and small Landau level filling factors ($ν$), near the termination of the fractional quantum Hall states. This WC phase exhibits an insulating behavior, reflecting its pinning by the small but finite disorder potential. An experimental determination of a $T$ vs $ν$ phase diagram for the melting of the WC, however, has proved to be challenging. Here we use capacitance measurements to probe the 2D WC through its effective screening as a function of $T$ and $ν$. We find that, as expected, the screening efficiency of the pinned WC is very poor at very low $T$ and improves at higher $T$ once the WC melts. Surprisingly, however, rather than monotonically changing with increasing $T$, the screening efficiency shows a well-defined maximum at a $T$ which is close to the previously-reported melting temperature of the WC. Our experimental results suggest a new method to map out a $T$ vs $ν$ phase diagram of the magnetic-field-induced WC precisely.

description: We apply the ideas of Alvarez and Labastida to the invariant of spin networks defined by Witten and Martin based on Chern-Simons theory. We show that it is possible to define ambient invariants of spin networks that (for the case of SU(2)) can be considered as extensions to spin networks of the Jones polynomial. Expansions of the coefficients of the polynomial yield primitive Vassiliev invariants. The resulting invariants are candidates for solutions of the Wheeler--DeWitt equations in the spin network representation of quantum gravity.

description: Introduction: Countries of the Eastern Mediterranean region (EMR) are facing both political and economic challenges, which lead to health and nutritional problems. Breastfeeding promotion can alleviate malnutrition and support achievement of the Sustainable Development Goals (SDGs). Objectives: To identify current status and future strategies for strengthening promotion of breastfeeding (BFP)in the EMR countries in conflict for achieving the SDGs. Methods: A survey questionnaire for status of BFP was sent to focal nutrition coordinators in the 22 countries of which14 countries responded. Data was compiled and underwent statistical analysis for types of communication messages, tools, populations targeted, management, monitoring and evaluation. Messages were divided into 3 groups: preventive (group I), supportive (group II) and protective messages (group III). The findings were correlated to exclusive breastfeeding (EBF), continued breastfeeding rates (CBF), mortality rates (MR) for children and maternal mortality rates (MMR). Results: Preventive messages for BFP were more commonly used in campaigns. Supportive and protective messages were less commonly used. Communication tools relied mainly on printed and written matter [100%] versus audiovisual and emedia tools [53.57% and 51.43% respectively]. Messages targeted mothers rather than other influential groups. CBF for 12 months correlated highly with social media [r0.77] at P<0.001. CBF for 24 months correlated with messages targeting influential groups [r0.81]at P<0.001.Under-five MR correlated with audiovisual tools [r0.44] at P<0.05. A framework for evidence-based communication strategies for the region was conceptualized and formulated into messages that can assist in achieving the SDGs. Conclusion: Government and support agencies need to invest in use of social media and audiovisuals aids and expand in use of supportive and protective messages for BFP, whilst supporting and protecting mothers through communication strategies targeting family members and policy makers.

Essays in Financial Engineering
Creators: Ahn, Andrew
Publisher: name: Columbia University
Year: 2014
Subjects: Operations research

description: This thesis consists of three essays in financial engineering. In particular we study problems in option pricing, stochastic control and risk management.
      In the first essay, we develop an accurate and efficient pricing approach for options on leveraged ETFs (LETFs). Our approach allows us to price these options quickly and in a manner that is consistent with the underlying ETF price dynamics. The numerical results also demonstrate that LETF option prices have model-dependency particularly in high-volatility environments.
      In the second essay, we extend a linear programming (LP) technique for approximately solving high-dimensional control problems in a diffusion setting. The original LP technique applies to finite horizon problems with an exponentially-distributed horizon, T. We extend the approach to fixed horizon problems. We then apply these techniques to dynamic portfolio optimization problems and evaluate their performance using convex duality methods. The numerical results suggest that the LP approach is a very promising one for tackling high-dimensional control problems.
      In the final essay, we propose a factor model-based approach for performing scenario analysis in a risk management context. We argue that our approach addresses some important drawbacks to a standard scenario analysis and, in a preliminary numerical investigation with option portfolios, we show that it produces superior results as well.

The weak coupling spectral solution of the DTV potential is related to the instanton partition function of supersymmetric QCD with surface operator. There are two strong coupling spectral solutions of the DTV potential, they are related to strong coupling expansions of gauge theory prepotential at the magnetic and dyonic points in the moduli space. A set of duality transformations relate the two strong coupling expansions for spectral solution, and for gauge theory prepotential.

STRUCTURE AND TUNING PATTERN IN THE IONIC DOUBLE CLATHRATE HYDRATES

Publisher: name: The University of British Columbia

description: A number of notable studies on pure ionic clathrate hydrates have utilized their unique ionic characteristics for electric applications, including their use as an electrolyte for nickel-metal hydride batteries. Although quaternary ammonium salt hydrates have recently been applied to gas separation and storage areas with the expectation of the small co-guest occupancy in empty cages, most of the researches have been oriented to macroscopic approaches based on hydrate phase equilibria and many other process variables. On the other hand, spectroscopic analyses for identifying the structure transition of ionic clathrate hydrates together with a comprehensive consideration of their complex phase patterns have not yet been reported in spite of their importance to the energy and environmental fields. Accordingly, in this study, we present the report of an extraordinary structural transition accompanying the occurrence of more than two coexisting clathrate hydrate phases and channel-induced tuning pattern in ionic double hydrate systems. In particular, the tuning observation uniquely occurring in the ionic clathrate hydrates is quite surprising, even though the tuning behavior is more commonly observed in the non-ionic hydrate systems. The remarkable feature of this work is that the icy ionic hydrate materials can be effectively used in energy devices. Moreover, the microscopic analyses of ionic clathrate hydrates for identifying the physicochemical characteristics are expected to provide new insights into a variety of inclusion chemistry fields.

description: Gromov (2001) and Sturm (2003) proved that any four points in a $\mathrm{CAT}(0)$ space satisfy a certain family of inequalities. We call those inequalities the $\boxtimes$-inequalities, following the notation used by Gromov. In this paper, we prove that a metric space $X$ containing at most five points admits an isometric embedding into a $\mathrm{CAT}(0)$ space if and only if any four points in $X$ satisfy the $\boxtimes$-inequalities. To prove this, we introduce a new family of necessary conditions for a metric space to admit an isometric embedding into a $\mathrm{CAT}(0)$ space by modifying and generalizing Gromov's cycle conditions. Furthermore, we prove that if a metric space satisfies all those necessary conditions, then it admits an isometric embedding into a $\mathrm{CAT}(0)$ space. This work presents a new approach to characterizing those metric spaces that admit an isometric embedding into a $\mathrm{CAT}(0)$ space.

 Material (one specimen): One adult specimen (MHNCUP/REP 268, formerly UP-MHNFCP-040729; Fig. S41), collected from unknown locality, date unknown.
 Comments: Trachylepis binotata is a large arboreal skink found in southwestern Angola and northwestern Namibia (Marques et al. 2018; Butler et al. 2019). Ferreira (1904, 1906) did not cite this specimen; however, the jar’s external tag is noted with the generic identification of “ Mabuia ”, an identification most likely done by him. Without locality information, we cannot assess whether the specimen falls inside the expected distribution range. Nevertheless, the specimen was most likely collected by Newton from Namibe Province, where this species is known to occur (Marques et al. 2018).

The Calogero side of the sixth Painlevé equation is known to be a non-autonomous version of the (rank one) elliptic model of Inozemtsev's extended Calogero systems. The fifth and fourth Painlevé equations correspond to the hyperbolic and rational models in Inozemtsev's classification. Those corresponding to the third, second and first are seemingly new. We further extend the correspondence to the higher rank models, and obtain a ``multi-component'' version of the Painlevé equations.

description: There is a general consensus among archaeologists that replacement of Neanderthals by anatomically modern humans in Europe occurred around 40–35 Ka. However, the causal mechanism for this replacement continues to be debated. Proposed models have featured either fitness advantages in favour of anatomically modern humans or invoked neutral drift under various preconditions. Searching for specific fitness advantages in the archaeological record has proven difficult, as these may be obscured, absent or subject to interpretation. To bridge this gap, we rigorously compare the system-level properties of fitness- and drift-based explanations of Neanderthal replacement. Our stochastic simulations and analytical predictions show that, although both fitness and drift can produce replacement, they present important differences in (i) required initial conditions, (ii) reliability, (iii) time to replacement, and (iv) path to replacement (population histories). These results present useful opportunities for comparison with archaeological and genetic data. We find greater agreement between the available empirical evidence and the system-level properties of replacement by differential fitness, rather than by neutral drift.

description: The control over the spectral broadening of an ensemble of emitters, mainly attributable to the size and shape dispersion and the homogenous broadening mechanisms, is crucial to several applications of quantum dots. We present a convenient self-assembly approach to deliver strain-free GaAs quantum dots with size distribution below 15%, due to the control of the growth parameters during the preliminary formation of the Ga droplets. This results in an ensemble photoluminescence linewidth of 19 meV at 14 K. The narrow emission band and the absence of a wetting layer promoting dot-dot coupling allow us to deconvolve the contribution of phonon broadening in the ensemble photoluminescence and study it in a wide temperature range.

description: I present a general framework allowing to carry out explicit calculation of the moment generating function of random matrix products $Π_n=M_nM_{n-1}\cdots M_1$, where $M_i$'s are i.i.d.. Following Tutubalin [Theor. Probab. Appl. {\bf 10}, 15 (1965)], the calculation of the generating function is reduced to finding the largest eigenvalue of a certain transfer operator associated with a family of representations of the group. The formalism is illustrated by considering products of random matrices from the group $\mathrm{SL}(2,\mathbb{R})$ where explicit calculations are possible. For concreteness, I study in detail transfer matrix products for the one-dimensional Schrödinger equation where the random potential is a Lévy noise (derivative of a Lévy process). In this case, I obtain a general formula for the variance of $\ln||Π_n||$ and for the variance of $\ln|ψ(x)|$, where $ψ(x)$ is the wavefunction, in terms of a single integral involving the Fourier transform of the invariant density of the matrix product. Finally I discuss the continuum limit of random matrix products (matrices close to the identity ). In particular, I investigate a simple case where the spectral problem providing the generalized Lyapunov exponent can be solved exactly.

description: We describe the application of scattering-type near-field optical microscopy to characterize various semiconducting materials using the electron storage ring Metrology Light Source (MLS) as a broadband synchrotron radiation source. For verifying high-resolution imaging and nano-FTIR spectroscopy we performed scans across nanoscale Si-based surface structures. The obtained results demonstrate that a spatial resolution below 40 nm can be achieved, despite the use of a radiation source with an extremely broad emission spectrum. This approach allows not only for the collection of optical information but also enables the acquisition of near-field spectral data in the mid-infrared range. The high sensitivity for spectroscopic material discrimination using synchrotron radiation is presented by recording near-field spectra from thin films composed of different materials used in semiconductor technology, such as SiO2, SiC, SixNy, and TiO2

Gas Kinematics and the Black Hole Mass at the Center of the Radio Galaxy NGC 4335

description: (abridged) We investigate the kinematics of the central gas disk of the radio-loud elliptical galaxy NGC 4335, derived from HST/STIS long-slit spectroscopic observations of Halpha+[NII] along 3 parallel slit positions. The observed mean velocities are consistent with a rotating thin disk. We model the gas disk in the customary way. This sets a 3 sigma upper limit of 10^8 Msun on black hole mass, Mbh. The velocity dispersion at r <0.5'' is in excess of that predicted by the thin rotating disk model. This does not invalidate the model, if the excess dispersion is caused by localized turbulent motion in addition to bulk circular rotation. However, if instead the dispersion is caused by the BH potential then a mass Mbh ~ 6x10^8 Msun is inferred by modeling the central gas dispersion as due to an isotropic spherical distribution of collisionless gas cloudlets. The stellar kinematics for NGC 4335 are derived from a ground-based (WHT/ISIS) long-slit observation along the galaxy major axis. A two-integral model of the stellar dynamics yields Mbh >= 3x10^9 Msun. However, there is reason to believe that this model overestimates Mbh. Reported correlations between black hole mass and inner stellar velocity dispersion sigma predict Mbh to be >= 5.4x10^8 Msun in NGC 4335. If our standard thin disk modeling of the gas kinematics is valid, then NGC 4335 has an unusually low Mbh for its velocity dispersion. If, on the other hand, this approach is flawed, and provides an underestimate of Mbh, then black hole masses for other galaxies derived from HST gas kinematics with the same assumptions should be treated with caution.

description: A topological group is minimal if it does not admit a strictly coarser Hausdorff group topology. The Roelcke uniformity (or lower uniformity) on a topological group is the greatest lower bound of the left and right uniformities. A group is Roelcke-precompact if it is precompact with respect to the Roelcke uniformity. Many naturally arising non-Abelian topological groups are Roelcke-precompact and hence have a natural compactification. We use such compactifications to prove that some groups of isometries are minimal. In particular, if U_1 is the Urysohn universal metric space of diameter 1, the group Iso(U_1) of all self-isometries of U_1 is Roelcke-precompact, topologically simple and minimal. We also show that every topological group is a subgroup of a minimal topologically simple Roelcke-precompact group of the form Iso(M), where M is an appropriate non-separable version of the Urysohn space.

description: Let $M$ be a symplectic manifold, equipped with a Hamiltonian action of a torus $T$. We give an explicit formula for the rational cohomology ring of the symplectic quotient $M//T$ in terms of the cohomology ring of $M$ and fixed point data. Under some restrictions, our formulas apply to integral cohomology. In certain cases these methods enable us to show that the cohomology of the reduced space is torsion-free.

description: Recently Yu. Bilu, P. Habegger and L. Kühne proved that no singular modulus can be a unit in the ring of algebraic integers. In this paper we study for which sets S of prime numbers there is no singular modulus that is an S-units. Here we prove that when the set S contains only primes congruent to 1 modulo 3 then no singular modulus can be an S-unit. We then give some remarks on the general case and we study the norm factorizations of a special family of singular moduli.

description: Trachylepis maculilabris (Gray, 1845)
 Material (one specimen): (MHNCUP/REP 272; Fig. S42), collected from unknown locality, date unknown.
 Comments: Trachylepis maculilabris is a human commensal species widely spread throughout sub-Saharan Africa that can be found in the northern regions of Angola and in scattered southern localities (Marques et al. 2018). Ceríaco et al. (2016c) had previously suggested that T. maculilabris constituted a species complex, which was confirmed in a recent phylogenetics study by Allen et al. (2019), with the authors uncovering four distinct lineages. Furthermore, Ceríaco et al. (2014a) noted that Angolan material seems to match the typical form of T. maculilabris and represents its most southwestern populations (Ceríaco et al. 2016c). Ferreira (1906) reported specimens from “Cambondo” and “Golungo” (adult and juvenile respectively), to which the extant specimen probably corresponds.

Small Denominators, Frequency Operators, and Lie Transforms for Nearly-Integrable Quantum Spin Systems

description: Based on the previously proposed notions of action operators and of quantum integrability, frequency operators are introduced in a fully quantum-mechanical setting. They are conceptually useful because a new formulation can be given to unitary perturbation theory. When worked out for quantum spin systems, this variant is found to be formally equivalent to canonical perturbation theory applied to nearly-integrable systems consisting of classical spins. In particular, it becomes possible to locate the quantum-mechanical operator-valued equivalent of the frequency denominators which may cause divergence of the classical perturbation series. The results established here link the concept of quantum-mechanical integrability to a technical question, namely the behaviour of specific perturbation series.
