description: This thesis is a compilation of essays on the extension of financial econometric techniques to various fields of financial and non-financial risk management-- namely, longevity risk, disaster risk and food security risk. First, longevity risk is quantified by proposing a mortality forecasting methodology based on a modified survival function and nonparametric residual-based bootstrapping. The parameters of the survival function are estimated through time and are modelled with a time series model structure. The estimated model is used to generate forecasts of parameter values and life expectancy. Confidence intervals are generated by residual-based bootstrapping through an autoregressive sieve based on the estimated model. The methodology is applied to life tables of male and female subjects from the United States, Australia and Japan, and compared with the Lee-Carter model in terms of forecasting life expectancy. From the results for the three countries, the proposed survival function has better long-term forecasting performance than does the Lee-Carter model. Second, a proposed methodology for estimating disaster risk is devised using bootstrapped multivariate extreme value theory methods. A disaster risk measure called storm-at-risk is created. The risk measure can be estimated through semiparametric and nonparametric approaches and is applied to weather extremes data generated by typhoons that enter the western North Pacific basin. Robustness checks on the performance of the approaches are conducted. The semiparametric approach performs better than the nonparametric approach in longer periods, but not in smaller periods. Third, food security risk is quantified by proposing risk measures for hierarchical agricultural time series data, which are generated for national and sub-national levels. The risk measures are created by a combination of forecast reconciliation methods for hierarchical time series data and residual-based bootstrapping methods. The methodology is applied to Philippine rice production time series data that are collected from the regions and are aggregated to the macro-regional and national levels.

Inhibiting PARP1 Splicing along with Inducing DNA Damage as Potential Breast Cancer Therapy

description: Triple negative breast cancer is a deadly cancer and once it has metastasized it is deemed incurable. The need for an effective therapy is rising, and recent therapies include targeting the DNA damage response pathway. PARP1 is one of the first responders to DNA damage, and has been targeted for inhibition along with the stimulation of DNA damage as a treatment for breast cancer. However, such treatments lack in specificity, and only target one or two domains of the PARP1 protein, whereas PARP1 has other functions pertaining to multiple cancer hallmarks such as promoting angiogenesis, metastasis, inflammation, life cycle regulation, and regulation of tumorigenic genes. In this project, we hypothesize that by inhibiting the PARP1 protein production, we will be able to effectively inhibit all cancer hallmarks that are facilitated by PARP1, and we achieve this by inhibiting the splicing of PARP1. Splicing is the removal of intervening sequences (introns) in the pre-mRNA and the joining of the expressed sequences (exons). For PARP1, we blocked intron 22 splicing by introducing an Antisense Morpholino Oligonucleotide (AMO) that blocks the binding of the spliceosome. The results obtained demonstrate that 50uM PARP1 AMO inhibits PARP1 splicing >88%, as well as inhibits protein production. Additionally, the combination of PARP1 AMO and Doxorubicin lead to a loss in cell proliferation

description: We continue our study of rich Galactic clusters by presenting deep CCD observations of both NGC 2168 (M35) and NGC 2323 (M50). Both clusters are found to be rich (NGC 2168 contains at least 1000 stars brighter than V = 22 and NGC 2323 contains approximately 2100 stars brighter than our photometric limit of V = 23) and young (age of NGC 2168 = 180 Myrs, age of NGC 2323 = 130 Myrs). The color-magnitude diagrams for the clusters exhibit clear main sequences stretching over 14 magnitudes in the V, B-V plane. Comparing these long main sequences with those of earlier clusters in the survey, as well as with the Hyades, has allowed for accurate distances to be established for each cluster (dist. of NGC 2168 = 912 +/- 70/65 pc, dist. of NGC 2323 = 1000 +/- 81/75 pc). Analysis of the luminosity and mass functions suggest that despite their young ages, both clusters are somewhat dynamically relaxed exhibiting signs of mass-segregation. This is especially interesting in the case of NGC 2323, which has an age of only 1.3 times the dynamical relaxation time. The present photometry is also deep enough to detect all of the white dwarfs in both clusters. We discuss some interesting candidates which may be the remnants of quite massive (M > 5 Mo) progenitor stars. The white dwarf cooling age of NGC 2168 is found to be in good agreement with the main-sequence turn-off age. These objects are potentially very important for setting constraints on the white dwarf initial-final mass relationship and upper mass limit for white dwarf production.

description: For any quantum algorithm given by a path in the space of unitary operators we define the computational complexity as the typical computational time associated with the path. This time is defined using a quantum time estimator associated with the path. This quantum time estimator is fully characterized by the Lyapunov generator of the path and the corresponding quantum Fisher information. The computational metric associated with this definition of computational complexity leads to a natural characterization of cost factors on the Lie algebra generators. Operator complexity growth in time is analyzed from this perspective leading to a simple characterization of Lyapunov exponent in case of chaotic Hamiltonians. The connection between complexity and entropy is expressed using the relation between quantum Fisher information about quantum time estimation and von Neumann entropy. This relation suggest a natural bound on computational complexity that generalizes the standard time energy quantum uncertainty. The connection between Lyapunov and modular Hamiltonian is briefly discussed. In the case of theories with holographic duals and for those reduced density matrix defined by tracing over a bounded region of the bulk, quantum estimation theory is crucial to estimate quantum mechanically the geometry of the tracing region. It is suggested that the corresponding quantum Fisher information associated with this estimation problem is at the root of the holographic bulk geometry.

description: The use of exactly-solvable Richardson-Gaudin (R-G) models to describe the physics of systems with strong pair correlations is reviewed. We begin with a brief discussion of Richardson's early work, which demonstrated the exact solvability of the pure pairing model, and then show how that work has evolved recently into a much richer class of exactly-solvable models. We then show how the Richardson solution leads naturally to an exact analogy between such quantum models and classical electrostatic problems in two dimensions. This is then used to demonstrate formally how BCS theory emerges as the large-N limit of the pure pairing Hamiltonian and is followed by several applications to problems of relevance to condensed matter physics, nuclear physics and the physics of confined systems. Some of the interesting effects that are discussed in the context of these exactly-solvable models include: (1) the crossover from superconductivity to a fluctuation-dominated regime in small metallic grains, (2) the role of the nucleon Pauli principle in suppressing the effects of high spin bosons in interacting boson models of nuclei, and (3) the possibility of fragmentation in confined boson systems. Interesting insight is also provided into the origin of the superconducting phase transition both in two-dimensional electronic systems and in atomic nuclei, based on the electrostatic image of the corresponding exactly-solvable quantum pairing models.

description: Ab initio theory describes nuclei from a fully microscopic formulation, with no presupposition of collective degrees of freedom, yet signatures of clustering and rotation nonetheless arise. We can therefore look to ab initio theory for an understanding of the nature of these emergent phenomena. To probe the nature of rotation in 10Be, we examine the predicted rotational spectroscopy from no-core configuration interaction (NCCI) calculations with the Daejeon16 internucleon interaction, and find spectra suggestive of coexisting rotational structures having qualitatively different intrinsic deformations: one triaxial and the other with large axial deformation arising primarily from the neutrons.

description: We use a multiannulus planetesimal accretion code to investigate the growth of icy planets in the outer regions of a planetesimal disk. In a quiescent minimum mass solar nebula, icy planets grow to sizes of 1000--3000 km on a timescale t = 15-20 Myr (a/30 AU)^3 where a is the distance from the central star. Planets form faster in more massive nebulae. Newly-formed planets stir up leftover planetesimals along their orbits and produce a collisional cascade where icy planetesimals are slowly ground to dust. The dusty debris of planet formation has physical characteristics similar to those observed in beta Pic, HR 4796A, and other debris disks. We derive dust masses for small particles, 1 mm and smaller, and large particles, 1 mm and larger, as a function of the initial conditions in the planetesimal disk. The dust luminosities derived from these masses are similar to those observed in Vega, HR 4796A, and other debris disks. The calculations produce bright rings and dark gaps. Bright rings occur where 1000 km and larger planets have recently formed. Dark gaps are regions where planets have cleared out dust or shadows where planets have yet to form.

 Eiphosoma laphygmae Costa Lima 1953: 181. [Original description. Holotype ♀, BRAZIL (Laboratorio Central de Patologia Vegetal, Ministerio de Agricultura, Rio de Janeiro, not examined). Synonymized under E. vitticolle Cresson by Townes & Townes 1966: 166. Revised combination by Gauld 2000: 106]
 [Eiphosoma vitticollis Cresson of authors. Misidentifications]
 Diagnosis. This species can be differentiated from all of the Neotropical species of Eiphosoma other than those belonging to the vitticolle species-group by the combination of short and deep anterior part of the submetapleural carina, hyaline forewing and presence of stout bristles on the shaft of the aedeagus. Among all Cuban species with an enclosed areolet, it is recognized by its mesopleuron conspicuously black marked with a more or less complete diagonal black line.
 Comments. Townes and Townes (1966) synonymized E. laphygmae and E. vitticolle. However, Gauld (2000) resurrected E. laphygmae from synonymy primarily because of different rearing records but also based on slight morphological and colour differences. In spite of Gauld’s statement about the extremely wide distribution and abundance of E. laphygmae, including Cuba, we have seen only three specimens housed in Cuban collections that could be assigned to this species. However, in those specimens the marks are not complete diagonal black lines extending from below the subalar prominence to the mesepisternal scrobe but are rather interrupted centrally appearing as two spots with the ventral one larger than the dorsal.

description: Activity coefficients, which are a measure of the non-ideality of liquid mixtures, are a key property in chemical engineering with relevance to modeling chemical and phase equilibria as well as transport processes. Although experimental data on thousands of binary mixtures are available, prediction methods are needed to calculate the activity coefficients in many relevant mixtures that have not been explored to-date. In this report, we propose a probabilistic matrix factorization model for predicting the activity coefficients in arbitrary binary mixtures. Although no physical descriptors for the considered components were used, our method outperforms the state-of-the-art method that has been refined over three decades while requiring much less training effort. This opens perspectives to novel methods for predicting physico-chemical properties of binary mixtures with the potential to revolutionize modeling and simulation in chemical engineering.

A Comparison of Measured Crab and Vela Glitch Healing Parameters with Predictions of Neutron Star Models

Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: There are currently two well-accepted models that explain how pulsars exhibit glitches, sudden changes in their regular rotational spin-down. According to the starquake model, the glitch healing parameter, Q, which is measurable in some cases from pulsar timing, should be equal to the ratio of the moment of inertia of the superfluid core of a neutron star (NS) to its total moment of inertia. Measured values of the healing parameter from pulsar glitches can therefore be used in combination with realistic NS structure models as one test of the feasibility of the starquake model as a glitch mechanism. We have constructed NS models using seven representative equations of state of superdense matter to test whether starquakes can account for glitches observed in the Crab and Vela pulsars, for which the most extensive and accurate glitch data are available. We also present a compilation of all measured values of Q for Crab and Vela glitches to date which have been separately published in the literature. We have computed the fractional core moment of inertia for stellar models covering a range of NS masses and find that for stable NSs in the realistic mass range 1.4 +/- 0.2 solar masses, the fraction is greater than 0.55 in all cases. This range is not consistent with the observational restriction Q < 0.2 for Vela if starquakes are the cause of its glitches. This confirms results of previous studies of the Vela pulsar which have suggested that starquakes are not a feasible mechanism for Vela glitches. The much larger values of Q observed for Crab glitches (Q > 0.7) are consistent with the starquake model predictions and support previous conclusions that starquakes can be the cause of Crab glitches.

description: It is well-known that tensor decompositions show separations, that is, that constraints on local terms (such as positivity) may entail an arbitrarily high cost in their representation. Here we show that many of these separations disappear in the approximate case. Specifically, for every approximation error $\varepsilon$ and norm, we define the approximate rank as the minimum rank of an element in the $\varepsilon$-ball with respect to that norm. For positive semidefinite matrices, we show that the separations between rank, purification rank, and separable rank disappear for a large class of Schatten $p$-norms. For nonnegative tensors, we show that the separations between rank, positive semidefinite rank, and nonnegative rank disappear for all $\ell_p$-norms with $p>1$. For the trace norm ($p = 1$), we obtain upper bounds that depend on the ambient dimension. We also provide a deterministic algorithm to obtain the approximate decomposition attaining our bounds. Our main tool is an approximate version of Carathéodory's Theorem. Our results imply that many separations are not robust under small perturbations of the tensor, with implications in quantum many-body systems and communication complexity.

description: Hexagonal boron nitride (h-BN) nanomesh, a two-dimensional insulating monolayer, grown on the (111) surface of rhodium exhibits an intriguing hexagonal corrugation pattern with a lattice constant of 3.2 nm. Despite numerous experimental and theoretical studies no quantitative agreement has been found on some details of the adsorption geometry such as the corrugation amplitude. The issue highlights the differences in chemical and electronic environment in the strongly bound pore regions and the weakly bound wire regions of the corrugated structure. For reliable results it is important to probe the structure with a method that is intrinsically sensitive to the position of the atomic cores rather than the electron density of states. In this work, we determine the corrugation of h-BN nanomesh from angle- and energy-resolved photoelectron diffraction measurements with chemical state resolution. By combining the results from angle and energy scans and comparing them to multiple-scattering simulations true adsorbate-substrate distance can be measured with high precision, avoiding pitfalls of apparent topography observed in scanning probe techniques. Our experimental results give accurate values for the peak to peak corrugation amplitude (0.80 A), the bonding distance to the substrate (2.20 A) and the buckling of the boron and nitrogen atoms in the strongly bound pore regions (0.07 A). The results are important for the development of theoretical methods involving the quantitative description of van der Waals systems like it requires the understanding of the physics of two-dimensional sp2 layers.

description: In concentrated solar thermal technologies, the receiver converts concentrated solar radiation into high-temperature heat. Solar receivers are commonly simulated with a stochastic integration method: Monte-Carlo ray-tracing. The optimisation of the geometry of receivers is challenging when using existing optimisation methods for two reasons: each receiver evaluation using Monte-Carlo ray-tracing requires significant computational effort and the outcome of a simulation involves uncertainty. A series of novel optimisation techniques are proposed to enable gradient-free, stochastic and multi-objective optimisation adapted to such problems. These techniques address the computational load difficulty and the challenge of conducting stochastic optimisation based on uncertain evaluations by introducing the concepts of “Progressive Monte-Carlo Evaluation (PMCE)”, “Intermediate Ray Emission Source (IRES)” and adaptive view-factor calculation. A new “Multi-Objective and Evolutionary PMCE Optimisation (MOEPMCE-O)” method is then built around PMCE to enable multi-objective geometrical optimisation of receivers. PMCE is shown to be able to reduce the computational time of a random search optimisation by more than 90% and is used in the geometrical design of a new receiver for the Australian National University SG4 dish concentrator that achieved 97.1% (±2.2%) of thermal efficiency during on-sun testing. MOE-PMCE-O is applied to a multi-objective tower receiver problem where liquid sodium is used as the receiver heat-carrier in a surround configuration heliostat field. A series of useful geometrical concepts emerge from the results, with geometrical features able to maintain high efficiency while keeping acceptable incident peak flux values with a moderate receiver total mass. Finally, a more fundamental look at the impact of the interaction of concentrating optics on the exergy of radiation available at the receiver location highlights the major role played by concentrator surface slope error in lowering the exergy in concentrated solar thermal systems and quantifies the exergy loss associated with non-ideal match between flux and surface temperature in receivers.

 Eiphosoma atrovittata Cresson 1865: 52. [Original description. Lectotype ♀, CUBA (ANSP, not examined). Designated by Cresson 1916: 18]
 Diagnosis. Lack of any of the specializations outlined above for the other species-groups separates E. atrovittatum from the rest of the Cuban species and puts it within the macrum species-group. The combination of smooth metapleuron, forewing with an infumate distal apex and a complete areolet, submetapleural carina not or weakly raised and propodeum yellow with median and lateral longitudinal black marks serve to identify this species.
 Comments. This is the only Cuban species belonging to the macrum species-group. It is distributed widely within Cuba, but only two specimens other than the lectotype were found in collections.

description: The leading order terms in a curvature expansion of the surface tension, the Tolman length (first order), and rigidities (second order) have been shown to play an important role in the description of nucleation processes. This work presents general and rigorous expressions to compute these quantities for any non-local density functional theory (DFT). The expressions hold for pure fluids and mixtures, and reduce to the known expressions from density gradient theory (DGT). The framework is applied to a Helmholtz energy functional based on the perturbed chain polar statistical associating fluid theory (PCP-SAFT) and is used for an extensive investigation of curvature corrections for pure fluids and mixtures. Predictions from the full DFT are compared to two simpler theories: predictive density gradient theory (pDGT), that has a density and temperature dependent influence matrix derived from DFT, and DGT, where the influence parameter reproduces the surface tension as predicted from DFT. All models are based on the same equation of state and predict similar Tolman lengths and spherical rigidities for small molecules, but the deviations between DFT and DGT increase with chain length for the alkanes. For all components except water, we find that DGT underpredicts the value of the Tolman length, but overpredicts the value of the spherical rigidity. An important basis for the calculation is an accurate prediction of the planar surface tension. Therefore, further work is required to accurately extract Tolman lengths and rigidities of alkanols, because DFT with PCP-SAFT does not accurately predict surface tensions of these fluids.

 This species was proposed by Brinkmann (1952a) to accommodate a single specimen collected by the LUCE of 1948-49 from the skin of the fine flounder, Paralichthys adspersus, caught off the coast of Chile (Golfo de Ancud, N of Isla Abtao; 41 o 47 ' 18 " S, 73 o 20 ' 55 " W). Two additional entobdellines from the same host species were collected on our behalf in 2004 by Dr M.T. González at Coquimbo, Chile (approximately 29°57’S, 71°25’W) (see Entobdella sp. 2, Table 2). Although this locality is approximately 1300 km north of the type locality, after comparison with the holotype, we conclude that the Coquimbo specimens are also E. brattstroemi.
In 1 specimen 2, possibly 3, seminal receptacles were visible (Fig. 35A) but the vagina was not identified.
 The accessory sclerites of Dr González’s specimens (Entobdella sp. 2; Table 2) are readily distinguishable from the accessory sclerites of other Entobdella spp. (Figs. 15H, 35B). Inner and outer flanges are prominent, but these flanges are noticeably different in shape from those of the specimens from H. macrops and occupy the distal third of the sclerite as opposed to the distal half in specimens from H. macrops (cf. Fig. 15F, G). The accessory sclerites of parasites from P. adspersus are also stouter than those in parasites from H. macrops. Unfortunately, the holotype is unflattened and heavily overstained and remounting the specimen did not yield any more useful anatomical information. However, what can be seen of the accessory sclerites in the holotype is consistent with the distinctive shapes of the accessory sclerites of Dr González’s specimens (Entobdella sp. 2; Table 2). The mean ratio of the lengths of the anterior hamuli and accessory sclerites based on the 3 adult parasites was 2.74 (Table 3). The tendon associated with the accessory sclerite terminates on the anterior (proximal) end of the anterior hamulus (Fig. 35A).
The entire ventral haptor surface, including the region anterior to the peduncle, is covered with papillae (Fig. 35A). The papillae in the regions lateral to the median sclerites are so dense that no radiating rows were discernible.
Eyes are present (Fig. 35A). The glands of Goto were not confirmed.

description: We provide a brief introduction to the high density effective theory of QCD. As an application, we consider the instanton correction to the perturbatively generated gap in the color superconducting phase. We show that the instanton correction becomes large for mu = 1.25 GeV in N_f=2 QCD, and for mu = 750 MeV in N_f=3 QCD with a massive strange quark. We also study some other numerical issues related to the magnitude of the gap. We find, in particular, that a renormalization group improved gap equation does not give results that are substantially different from a gap equation with a fixed coupling.

description: In the previous paper we have introduced the LARES 2 space experiment. The LARES 2 laser-ranged satellite is planned for a launch in 2019 with the new VEGA C launch vehicle of the Italian Space Agency (ASI), ESA and ELV. The main objectives of the LARES 2 experiment are accurate measurements of General Relativity, gravitational and fundamental physics and accurate determinations in space geodesy and geodynamics. In particular LARES 2 is aimed to achieve a very accurate test of frame-dragging, an intriguing phenomenon predicted by General Relativity. Here we report the results of Monte Carlo simulations and covariance analyses fully confirming an error budget of a few parts in one thousand in the measurement of frame-dragging with LARES 2 as calculated in our previous paper.

description: Entobdella rosaceus Crane, 1972
(Fig. 15K)
 Crane’s (1972) description is based on a single specimen from the skin of a round-bodied host, the pink seaperch, Zalembius rosaceus. Reference to the holotype (broken transversely into an anterior and posterior half) reveals some errors. The whole animal is shown in Crane’s fig. 1 and with reference to the haptor this is a ventral view. However, the common genital opening is shown on the right margin of the body. In the text the common genital opening is said to be located on the left body margin, as in other entobdellines, and our observations on the holotype confirm that this is the correct location of the common genital opening in E. rosaceus. In Crane’s fig. 2, the uterus is incorrectly labelled “vagina” and the ootype is mislabelled as “uterus”. The vagina is not illustrated and we were unable to find it in the holotype. Seminal receptacles are hard to resolve but at least 2 and possibly 4 are present. Glands of Goto and eyes are present.
 Crane claimed that E. rosaceus is the only species of Entobdella in which the “posterior anchor” (= posterior hamulus) has a “long, thin root” extending anteriorly. We confirmed the observation of Klassen et al. (1989) that this anterior root is not part of the sclerite. Papillae are present on the ventral haptor surface. The tendon associated with the accessory sclerite terminates on the proximal part of the anterior hamulus and the accessory sclerite is strongly curved distally (Fig. 15K).

description: We show that the minimization of the Lagrangian action functional on suitable classes of symmetric loops yields collisionless periodic orbits of the n-body problem, provided that some simple conditions on the symmetry group are satisfied. More precisely, we give a fairly general condition on symmetry groups G of the loop space for the n-body problem (with potential of homogeneous degree alpha, with alpha>0) which ensures that the restriction of the Lagrangian action to the space of G-equivariant loops is coercive and its minimizers are collisionless, without any strong force assumption. Many of the already known periodic orbits can be proved to exist by this result, and several new orbits are found with some appropriate choice of G.

Feasibility of the ion-trap simulation of a class of non-equilibrium phase transitions

description: Our work analyzes the potential of ion traps for the experimental simulation of non-equilibrium phase transitions observed in certain spin-chain models which can be mapped to free-fermion systems. In order to make the dynamics more accessible to an experimenter, we first consider relatively small systems, with few particles. We analyze phase transitions in the non-equilibrium asymptotic regimes of an XY spin chain with a transverse magnetic field and coupled to Markovian baths at the end sites. We study a static open system and a case when the spin chain is periodically kicked. Notably, in the latter case for some anisotropy parameters the dependence on the system size converges rapidly to the many-particle limit, thus facilitating the experimental observation of the dynamics. We also define local observables that indicate the presence of the quantum phase transitions of interest, and we study the effects of the long-range character of the typical interactions obtained in ion traps.

description: We present the chemical composition of the bright companion to the millisecond pulsar J1740-5340 in NGC 6397, based on high resolution spectra. Though the large rotation velocity of the star broadens the lines and complicates the analysis, the derived abundances are found fully compatible with those of normal unperturbed stars in NGC 6397, with the exception of a few elements (Li, Ca, and C). The lack of C suggests that the star has been peeled down to regions where incomplete CNO burning occurs, favouring a scenario where the companion is a turn-off star which has lost most of its mass. In addition we found an unexpected large Li abundance, which suggests that fresh 7Li has been produced on the stellar surface.

Chaperone assisted translocation

Year: 2004
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We investigate the translocation of a stiff polymer through a nanopore in a membrane, in the presence of binding particles (chaperones) that bind reversibly to the polymer on both sides of the membrane. A bound chaperone covers one (univalent binding) or many (multivalent binding) binding sites. Assuming that the diffusion of the chaperones is fast compared to the rate of translocation we describe the process by a one-dimensional master equation. We expand previous models by a detailed study of the effective force in the master equation, which is obtained by the appropriate statistical mechanical average over the chaperone states. The dependence of the force on the degree of valency (the number of binding sites occupied by a chaperone) is studied in detail. We obtain finite size corrections (to the thermodynamical expression for the force), which, for univalent binding, can be expressed analytically. We finally investigate the mean velocity for translocation as a function of chaperone binding strength and size. For both univalent and multivalent binding simple results are obtained for the case of a sufficiently long translocating polymer.
