description: Objective: To determine whether family history of pre-eclampsia and cardiovascular disease is consistently associated with the occurrence of pre-eclampsia sub-phenotypes and fetal growth restriction (FGR). Material and Methods: We conducted a case-control study in which cases of pre-eclampsia and healthy pregnant controls were recruited at the time of delivery from eight Colombian cities between 2000 and 2012. Odds of pre-eclampsia among women with a positive family history of pre-eclampsia or cardiovascular disease were compared to women without affected relatives (logistic regression modeling and multinomial logistic regression model [Ajusted]). Results: A total of 3510 pre-eclampsia cases and 4512 controls with data on family history of pre-eclampsia were included in analyses. A subsample of 3086 cases and 3888 controls also provided information on family history of cardiovascular disease. Women whose mothers had pre-eclampsia had 3.38 (95% CI 2.89, 3.96) higher odds than those who did not, and having an affected sister increased pre-eclampsia odds by 2.43 (95% CI 2.02, 2.93). The effect of having both mother and sister affected with pre-eclampsia was stronger than the two independent risk factors (OR 4.17 [95% CI 2.60, 6.69]). Women with parental history of cardiovascular disease also had an increased risk of pre-eclampsia (OR 1.58 [95% CI 1.24, 2.01]). Conclusions: Family history of pre-eclampsia increased the risk of PE. The impact of family history of cardiovascular disease on pre-eclampsia was more conservative, but serves to support the hypothesis that pre-eclampsia may reflect the premature exposure of underlying cardiovascular dysfunction, precipitated by the stress test of pregnancy.

description: Molecular electronic spectra can be represented in the time domain as auto-correlation functions of the initial vibrational wavepacket. We present a derivation of the harmonic vibrational auto-correlation function that is valid for both real and imaginary harmonic frequencies. The derivation rests on Lie algebra techniques that map otherwise complicated exponential operator arithmetic to simpler matrix formulae. The expressions for the zero- and finite-temperature harmonic auto-correlation functions have been carefully structured both to be free of branch-cut discontinuities and to remain numerically stable with finite-precision arithmetic. Simple extensions correct the harmonic Franck-Condon approximation for the lowest-order anharmonic and Herzberg-Teller effects. Quantitative simulations are shown for several examples, including the electronic absorption spectra of F$_2$, HOCl, CH$_2$NH, and NO$_2$.

title: Structure-borne noise of marine diesel engines: transfer-path analysis of onboard transmission and underwater radiation
Creators: name: Fragasso, Jacopo
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Onboard machinery generates structure-borne noise that propagates onboard and underwater. Structure-borne noise has a direct influence on the onboard noise comfort and the underwater noise footprint of the vessel. Vibrational transfer-path analysis (TPA) can be used to understand how noise is transmitted from onboard noise sources to the ship structures or radiated underwater. The focus of this research is on the noise radiated from resiliently-mounted marine diesel engines because of their dominant impact on the noise signature of the vessel. With TPA, the main components of the vibrational transfer path are analyzed separately and then combined together. Noise levels at the receiver can be reduced by identifying the critical points in the transfer path and improving their design. The characterization of the vibration isolator mounted under the diesel engine is performed with the use of numerical models built and validated with the aid of experimental tests and response surface methodology (RSM). Similarly, a finite-element model for the analysis of underwater sound radiation of vibrating structures is developed using sound and vibration measurements acquired with acoustic measurements in a water tank. This work presents an experimental procedure for the characterization of the vibration isolator at different static preloads. The dynamic response of a numerical simulation is fit to the experimental response using a hyperelastic material model and an implicit timeintegration scheme. Moreover, the coupled acoustic-structural analysis of the underwater radiation yields accurate results and provides a coefficient of sound radiation (σ). An analytical formulation of the transfer path is developed to combine the contributions of the components of the transfer path to estimate noise and vibration levels at the receiving point. This thesis highlights the importance of numerical models in the TPA of structure-borne noise and shows how dynamic simulations can help ship designers estimate the contribution of the components of the transfer path using standardized testing procedures and model-scale experiments.

description: We give a detailed exposition of the formalism of Kinetic Field Theory (KFT) with emphasis on the perturbative determination of observables. KFT is a statistical non-equilibrium classical field theory based on the path integral formulation of classical mechanics, employing the powerful techniques developed in the context of quantum field theory to describe classical systems. Unlike previous work on KFT, we perform the integration over the probability distribution of initial conditions in the very last step. This significantly improves the clarity of the perturbative treatment and allows for physical interpretation of intermediate results. We give an introduction to the general framework, but focus on the application to interacting $N$-body systems. Specializing the results to cosmic structure formation, we reproduce the linear growth of the cosmic density fluctuation power spectrum on all scales from microscopic, Newtonian particle dynamics alone.

description: Galaxy sizes and their evolution over cosmic time have been studied for decades and serve as key tests of galaxy formation models. However, at $z\gtrsim1$ these studies have been limited by a lack of deep, high-resolution rest-frame infrared imaging that accurately traces galaxy stellar mass distributions. Here, we leverage the new capabilities of the James Webb Space Telescope to measure the 4.4$μ$m sizes of ${\sim}1000$ galaxies with $\log{\rm{M}_*/\rm{M}_\odot}\ge9$ and $1.0\le z \le 2.5$ from public CEERS imaging in the EGS deep field. We compare the sizes of galaxies measured from NIRCam imaging at 4.4$μ$m ($λ_{\mathrm{rest}}\sim1.6μ$m) with sizes measured at $1.5μ$m ($λ_{\mathrm{rest}}\sim5500$A). We find that, on average, galaxy half-light radii are $\sim8$% smaller at 4.4$μ$m than 1.5$μ$m in this sample. This size difference is markedly stronger at higher stellar masses and redder rest-frame $V-J$ colors: galaxies with ${\rm M}_* \sim 10^{11}\,{\rm M}_\odot$ have 4.4$μ$m sizes that are $\sim 25$% smaller than their 1.5$μ$m sizes. Our results indicate that galaxy mass profiles are significantly more compact than their rest-frame optical light profiles at cosmic noon, and demonstrate that spatial variations in age and attenuation are important, particularly for massive galaxies. The trend that we find here impacts our understanding of the size growth and evolution of galaxies, and suggests that previous studies based on rest-frame optical light may not have captured the mass-weighted structural evolution of galaxies. This paper represents a first step towards a new understanding of the morphologies of early massive galaxies enabled by JWST's infrared window into the distant universe.

description: An expert of Greek poetry and editor of Archilochus with André Bonnard, the Swiss scholar François Lasserre (1919-1989) was the initiator of the Strabo edition in the Collection des Universités de France: he personally published seven books of Strabo as well as the introduction to the text and its history. The project began in 1949/1950 during a research fellowship at the Swiss In­stitute in Rome where Lasserre studied the manuscript tradition of Strabo’s Geography and especially its most ancient testimony, the Vatican palimpsest. He produced a diplomatic edition of the Vatican manuscript which is im­portant to this day for portions of the text that has become illegible in the original. Some of Lassere’s letters to Paola Zancani Montuoro and Wolfgang Aly are here edited: the letters display his ongoing studies of the palimpsest.

description: Two independent groups reported the discovery of an isolated dark stellar remnant in the microlensing event OGLE-2011-BLG-0462 based on photometric ground-based observations coupled with astrometric measurements taken with the Hubble Space Telescope. These two analyses yielded discrepant mass measurements, with the first group reporting that the lensing object is a black hole of 7.1 +/- 1.3 solar masses whereas the other concluded that the microlensing event was caused by either a neutron star or a low-mass black hole (1.6-4.4 solar masses). Here, we scrutinize the available photometric and astrometric data and conclude that systematic errors are a cause of the discrepant measurements. We find that the lens is an isolated black hole with a mass of 7.88 +/- 0.82 solar masses located at a distance of 1.49 +/- 0.12 kpc. We also study the impact of blending on the accuracy of astrometric microlensing measurements. We find that low-level blending by source companions is a major, previously unrecognized, challenge to astrometric microlensing measurements of black hole masses.

description: Cisplatin (CDDP) is an efficient chemotherapeutic drug, whose use is associated with the development of serious undesired toxicities, such as nephrotoxicity. The human organic cation transporter 2 (hOCT2), which is highly expressed in the basolateral membrane domain of renal proximal tubules seems to play an important role in the development of CDDP nephrotoxicity. The role of angiotensin II (AII) signaling by binding to the AII receptor type 1 (AT1R) in the development and/or progression of CDDP nephrotoxicity is debated. Therefore, in this work, the regulation of hOCT2 activity by AII and its role in the development of CDDP cellular toxicity was investigated. To do this, hOCT2 was overexpressed by viral transduction in Madin–Darby Canine Kidney (MDCK) cells which were cultivated on a filter. This approach allows the separation of an apical and a basolateral membrane domain, which are easily accessible for experimentation. In this system, hOCT2 was mainly localized on the basolateral plasma membrane domain of the cells. The transporter was functional since a specific uptake of the fluorescent organic cation 4-(4-(dimethylamino)styryl)-N-methylpyridinium (ASP+) with an affinity (Km) of 35 µM was only detectable by the addition of ASP+ to the basolateral compartment of hOCT2 expressing MDCK (hOCT2-MDCK) cells. Similarly, CDDP toxicity was evident mainly by CDDP addition to the basolateral compartment of hOCT2-MDCK cells cultivated on a filter. The addition of 1 nM AII stimulated hOCT2 function via PKC activation and worsened CDDP cytotoxicity via binding to AT1R. Therefore, the AII signaling pathway may be implicated in the development and/or progression of CDDP nephrotoxicity. This signaling pathway may be a target for protective interventions for example by blocking AT1R in the kidneys. However, it should be further investigated whether these findings obtained in a cell culture system may have translational relevance for the clinical situation. For toxicity experiments, a 100 µM CDDP concentration was used, which is high but allows us to identify clearly toxic effects due to hOCT2. In summary, down-regulation of hOCT2 activity by the inhibition of the AII signaling pathway may protect against CDDP nephrotoxicity.

description: Superconducting transition-edge sensor (TES) microcalorimeters have great utility in x-ray applications owing to their high energy resolution, good collecting efficiency and the feasibility of being multiplexed into large arrays. In this work, we develop hard x-ray TESs to measure the absolute energies of muonic-argon ($μ$-Ar) transition lines around 44 keV and 20 keV. TESs with sidecar absorbers of different heat capacities were fabricated and characterized for their energy resolution and calibration uncertainty. We achieved ~ 1 eV absolute energy measurement accuracy at 44 keV, and < 12 eV energy resolution at 17.5 keV.

description: The aim of this article is to focus on the baron de Sainte-Croix (1746-1809), classicist and historian, and the role of the geography in his scholarly activity, also from a methodological point of view. Starting with the geographical researches concerning the historians of Alexander the Great’s expedition, the baron continued to give great attention to geography quite in every subject he investigated (the colonies, for example). The most relevant of the geographical subjects he considered were: the Caspian sea and the Caucase, Nearchus’ navigation, Pseudo-Skylax Periplous, Isidore of Charax, and in general far east regions. He also projected an edition of the ‘minor’ geographers.

description: We study the radial quantization of the 3d O(N) vector model. We calculate the higher spin charges whose commutation relations give the higher spin algebra. The Fock states of higher spin gravity in AdS_{4} are realized as the states in the 3d CFT. The inner products between these states encode dynamical information. The construction of bulk operators from CFT is discussed as well. This serves as the simplest explicit demonstration of the CFT definition for the quantum gravity.

description: The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design combines the knowledge and expertise gathered by the European solar physics community during the construction and operation of state-of-the-art solar telescopes operating in visible and near-infrared wavelengths: the Swedish 1m Solar Telescope (SST), the German Vacuum Tower Telescope (VTT) and GREGOR, the French Télescope Héliographique pour l'Étude du Magnétisme et des Instabilités Solaires (THÉMIS), and the Dutch Open Telescope (DOT). With its 4.2 m primary mirror and an open configuration, EST will become the most powerful European ground-based facility to study the Sun in the coming decades in the visible and near-infrared bands. EST uses the most innovative technological advances: the first adaptive secondary mirror ever used in a solar telescope, a complex multi-conjugate adaptive optics with deformable mirrors that form part of the optical design in a natural way, a polarimetrically compensated telescope design that eliminates the complex temporal variation and wavelength dependence of the telescope Mueller matrix, and an instrument suite containing several (etalon-based) tunable imaging spectropolarimeters and several integral field unit spectropolarimeters. This publication summarises some fundamental science questions that can be addressed with the telescope, together with a complete description of its major subsystems.

Taming the post-Newtonian expansion: Simplifying the modes of the gravitational wave energy flux at infinity for a point particle in a circular orbit around a Schwarzschild black hole

description: (Abridged) High-order terms in the post-Newtonian (PN) expansions of various quantities for compact binaries exhibit a combinatorial increase in complexity, including ever-increasing numbers of transcendentals. Here we consider the gravitational wave energy flux at infinity from a point particle in a circular orbit around a Schwarzschild black hole, which is known to 22PN beyond the lowest-order Newtonian prediction, at which point each order has over 1000 terms. We introduce a factorization that considerably simplifies the spherical harmonic modes of the energy flux (and thus also the amplitudes of the spherical harmonic modes of the gravitational waves); it is likely that much of the complexity this factorization removes is due to curved-space wave propagation (e.g., tail effects). For the modes with azimuthal number l of 7 or greater, this factorization reduces the expressions for the modes that enter the 22PN total energy flux to pure integer PN series with rational coefficients, which amounts to a reduction of up to a factor of ~150 in the total number of terms in a given mode. The reduction in complexity becomes less dramatic for smaller l, due to the structure of the expansion, though the factorization is still able to remove all the half-integer PN terms. For the 22PN l = 2 modes, this factorization still reduces the total number of terms (and size) by a factor of ~10 and gives purely rational coefficients through 8PN. This factorization also improves the convergence of the series, though we find the exponential resummation introduced for the full energy flux by Isoyama et al. to be even more effective at improving the convergence of the individual modes, producing improvements of over four orders of magnitude over the original series for some modes. However, the exponential resummation is not as effective at simplifying the series, particularly for the higher-order modes.

description: The spatio-spectral total variation (SSTV) model has been widely used as an effective regularization of hyperspectral images (HSI) for various applications such as mixed noise removal. However, since SSTV computes local spatial differences uniformly, it is difficult to remove noise while preserving complex spatial structures with fine edges and textures, especially in situations of high noise intensity. To solve this problem, we propose a new TV-type regularization called Graph-SSTV (GSSTV), which generates a graph explicitly reflecting the spatial structure of the target HSI from noisy HSIs and incorporates a weighted spatial difference operator designed based on this graph. Furthermore, we formulate the mixed noise removal problem as a convex optimization problem involving GSSTV and develop an efficient algorithm based on the primal-dual splitting method to solve this problem. Finally, we demonstrate the effectiveness of GSSTV compared with existing HSI regularization models through experiments on mixed noise removal.

Comparative growth and leaf nutrition of selected roselle (Hibiscus sabdariffa) genotypes in New Jersey
Creators: name: Sanders, Mara C.
Publisher: name: No Publisher Supplied
Year: 2018

description: In an age of rapid technological advances it is deeply concerning that every person does not have access to the clean food and water they need for basic human development, leaving many with lasting developmental problems. Feeding the world has been the aim of many aid organizations, governments and charities and although advances have been made in increasing the basic caloric intake, access to fruit, vegetables and pulses to ensure adequate nutrition. More recently traditional, local and indigenous vegetables have become increasingly popular as people look to decrease their ecological impact while increasing access to nutritious foods. Smallholder farmers and family farms have an opportunity to meet the increasing demand for indigenous vegetables while increasing income and rural development. African indigenous vegetables such as roselle (Hibiscus sabdariffa) have the potential to create income for farmers, while providing a source of nutritious vegetables for themselves and their families. The objective of this study was to determine the yield and nutrition of four field-grown roselle genotypes over a two year time period. The genotypes chosen (African Green, Indian Red, Indian Variegated, and Thai Red) were chosen based on the regional demand for ethnic vegetables in the Northeast United States. African Green roselle yielded the highest dry weight, 81.89 grams, per plant harvested every two weeks over the growing season, followed by Indian Variegated (79.94g), Indian Red (74.23g) and Thai Red (55.70g). Indian Red yielded the highest when harvested every three weeks (100.41g) with Indian Variegated yielding a similar amount (91.94g) and African Green with the least (64.31g). Field production trials were conducted in New Jersey at the Rutgers Experimental field stations in 2017 and 2018. In all varieties, roselle was found to have 2% of the daily-recommended dose of Calcium and Potassium. 230g of dried roselle leaves are required to meet the daily minimum calcium, iron and potassium needs of children 1-8 years old. Further information is needed in the impacts of leaf harvesting on calyx production as well as the development of an early blooming cultivar with increased nutrition. Overall, indigenous vegetables such as roselle can serve as a model for other specialty ethnic crops in their transition to commercial specialty crops. Results observed and information learned can be transferred to growers in the developing world such as sub-Sahara Africa.  Empowering smallholder farmers with new technologies, such as improved seeds, and innovations in agriculture can facilitate the growth of high quality products and rural communities worldwide.

Measuring the Intangible Values of Natural Streams, Part I

description: Abstract:
The purpose of this study was to apply the "uniqueness concept" to the quantification of the intangible values of natural streams. The methodology is based on procedures developed by Luna B. Leopold and Maria O. Marchand of the U.S. Geological Survey. It involves the evaluation of a set of characteristics or factors for selected stream sites. Each factor is rated for each site on a numerical scale indicative of the range of possible "values" for that factor. An "uniqueness ratio" (the reciprocal of the number of stream sites sharing a given category rating) is then computed for each stream for each factor in the set. Summing the "uniqueness ratios" for all the factors for a given stream yields a "total uniqueness ratio". Those streams with the highest "total uniqueness ratio" are considered to be the most unique. The present study utilized an inventory of fifty-four factors which were evaluated for each study stream. The inventory was divided into five factor groups: Physical Measures, Land Use Measures, Water Quality Measures, Disvalues and Esthetic Impression Measures.
Two types of streams were studied: Preference streams and Random streams. Sixteen Preference streams were selected from lists of wild, scenic and recreational streams prepared by two state agencies. Forty-two Random streams were selected, using a random number table, from a small watershed inventory prepared by the U.S. Soil Conservation Service. The sampling process insured that streams be selected from each of the eight physiographic regions of Kentucky. Thus, a total of fifty-eight streams were studied.
Conclusions reached were:
(1)The "uniqueness ratio" concept can successfully be used to evaluate "relative uniqueness" within a group of streams. (2)Higher values of the "total uniqueness ratio" were obtained for those streams that were in "bad" condition or that had been abused by man's activities than for those streams that were of relatively high quality. (3)Some of the streams ranking highest in "total uniqueness" were those situated in highly developed areas, an indication of the essentially rural nature of the state of Kentucky and the effects of development and urbanization on the environmental quality of small watersheds. (4)Streams located in the Eastern Coal Field generally represented the most natural, rugged, and esthetic streams of the study. (5)The streams located in the Western Coal Field generally represented the most highly exploited and least esthetic streams of the study.

The Spatial Structure of Economic Exchange and Rural Prosperity in the United States
Creators: name: Dunn, Richard A.

Subjects: subject: Community/Rural/Urban Development
subject: rural
subject: policy

description: There is a nascent discussion among policymakers and researchers that rural areas may be disadvantaged by their location within the supply-chain as providers of raw and minimally processed inputs to centers of production located elsewhere. This paper makes several important contributions to this emerging policy discussion. First, we formalize a new concept of intermediate circularity that characterizes the production and trade of intermediates, i.e., goods and services that are transformed and combined to produce other goods and services. Second, we use this model to derive a collection of measures that quantify the shape of economic activity. Third, we calculate feasible versions of these measures by applying the input-output framework and we compare their distribution across metro and non-metro counties of the United States. Finally, we estimate the relationship between these measures of intermediate circularity and indicators of economic performance. We find that the distributions of intermediate circularity indicators differ across metro and non-metro counties, as do their correlations with economic growth. Intermediate inputs tend to account for a larger share of output in non-metro counties and are more intensively exported. These attributes are associated with lower growth in both metro and non-metro counties. On the other hand, while using intermediate inputs is associated with growth in non-metro counties, the opposite is true in metro counties. Implications for policymakers who might consider incentivizing the spatial reorganization of economic activity with the aim of increasing rural prosperity, reducing urban-rural inequality, or improving the resilience of rural economies are discussed.

description: The discovery of extended gamma-ray emission toward a number of middle-aged pulsars suggests the possibility of long-lived particle confinement beyond the classical pulsar wind nebula (PWN) stage. How this emerging source class can be extrapolated to a Galactic population remains unclear. We aim to evaluate how pulsar halos fit in existing TeV observations, under the assumption that all middle-aged pulsars develop halos similar to those observed toward the J0633+1746 or B0656+14 pulsars. We modeled the populations of supernova remnants, PWNe, and pulsar halos in the Milky Way. The PWN-halo evolutionary sequence is described in a simple yet coherent framework, and both kinds of objects are assumed to share the same particle injection properties. We then assessed the contribution of the different source classes to the very-high-energy emission from the Galaxy. The synthetic population can be made consistent with the flux distribution of all known objects, including unidentified objects, for a reasonable set of parameters. The fraction of the populations predicted to be detectable in surveys of the Galactic plane with HESS. and HAWC is then found to be in good agreement with their actual outcome, with a number of detectable halos ranging from 30 to 80% of the number of detectable PWNe. Prospects for CTA involve the detection of 250-300 sources in the Galactic Plane Survey, including 170 PWNe and up to 100 halos. The extent of diffusion suppression in halos has a limited impact on such prospects but its magnitude has a strong influence. The level of diffuse emission from unresolved populations in each survey is found to be dominated by halos and comparable to large-scale interstellar radiation powered by cosmic rays above 0.1-1TeV. Pulsar halos are shown to be viable counterparts to a fraction of the currently unidentified sources if they develop around most middle-aged pulsars (abridged).

A Simple Character String Proof of the "True but Unprovable" Version of Gödel's First Incompleteness Theorem

description: A rather easy yet rigorous proof of a version of Gödel's first incompleteness theorem is presented. The version is "each recursively enumerable theory of natural numbers with 0, 1, +, *, =, logical and, logical not, and the universal quantifier either proves a false sentence or fails to prove a true sentence". The proof proceeds by first showing a similar result on theories of finite character strings, and then transporting it to natural numbers, by using them to model strings and their concatenation. Proof systems are expressed via Turing machines that halt if and only if their input string is a theorem. This approach makes it possible to present all but one parts of the proof rather briefly with simple and straightforward constructions. The details require some care, but do not require significant background knowledge. The missing part is the widely known fact that Turing machines can perform complicated computational tasks.

description: Gravitational wave astronomy is a vibrant field that leverages both classic and modern data processing techniques for the understanding of the universe. Various approaches have been proposed for improving the efficiency of the detection scheme, with hierarchical matched filtering being an important strategy. Meanwhile, deep learning methods have recently demonstrated both consistency with matched filtering methods and remarkable statistical performance. In this work, we propose Hierarchical Detection Network (HDN), a novel approach to efficient detection that combines ideas from hierarchical matching and deep learning. The network is trained using a novel loss function, which encodes simultaneously the goals of statistical accuracy and efficiency. We discuss the source of complexity reduction of the proposed model, and describe a general recipe for initialization with each layer specializing in different regions. We demonstrate the performance of HDN with experiments using open LIGO data and synthetic injections, and observe with two-layer models a $79\%$ efficiency gain compared with matched filtering at an equal error rate of $0.2\%$. Furthermore, we show how training a three-layer HDN initialized using two-layer model can further boost both accuracy and efficiency, highlighting the power of multiple simple layers in efficient detection.
