description: We develop a generalized dynamic factor model for panel data with the goal of estimating an unobserved index. While similar models have been developed in the literature of dynamic factor analysis, our contribution is threefold. First, contrary to simple dynamic factor analysis where multiple attributes of the same subject are measured at each time period, our model also accounts for multiple subjects. It is therefore suitable to a panel data framework. Second, our model estimates a unique unobserved index for every subject for every time period, as opposed to previous work where a temporal index common to all subjects was used. Third, we develop a novel iterative estimation process which we call the Two-Cycle Conditional Expectation-Maximization (2CCEM) algorithm and is flexible enough to handle a variety of different types of datasets. The model is applied on a panel measuring attributes related to the operation of water and sanitation utilities.

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

title: The design of acyl modified co-enzyme-A ester analogues as enzyme inhibitors
Creators: name: Rubanu, Maria Grazia
Publisher: name: University of St Andrews
Year: 2019

description: This thesis is focused on the design and synthesis of analogues of thioesters of Co-enzyme A which are involved in many important biosynthetic pathways. Acetyl-CoA is converted into citrate by citrate synthase in the first step of the Krebs cycle that is central for the cellular respiration. Chapter 2 is focused on the successful synthesis of five analogues of acetyl-CoA and their investigation as inhibitors of citrate synthase. This project is based on the finding that Fluorovinyl thioether-CoA (FV-CoA) is a micromolar inhibitor of citrate synthase (Kᵢᵃᵖᵖ = 4.4 µM). Sulfoxide-CoA, with a sulfonyl and a methylene group replacing the carbonyl group and the sulfur atom of acetyl-CoA, was found to be a modest micromolar inhibitor of citrate synthase (11.1 µM), indicating its potential as hydrogen bonding acceptor. The remaining compounds showed poor or too low binding affinity for the enzyme. Although these compounds showed poor inhibitory capacity towards citrate synthase, they could be potential inhibitors of other acetyl-CoA utilizing enzymes, such as malate synthase that catalyzes the conversion of acetyl-CoA into malate. Its activity is correlated to different pathogens pathway (Mycobacterium tubercolosis) and its regulation could potentially prevent the bacterial growth. Chapter 3 describes the attempted synthesis of a fluorovinyl thioacrylate derivative as malonyl-CoA analogue and potential covalent inhibitor of acetyl-CoA carboxylase (ACC). ACC catalyzes the irreversible conversion of acetyl-CoA into malonyl-CoA in the first step of fatty acid synthesis. The regulation of ACC is associated to many cardiovascular diseases such as diabetes, obesity and its inhibition can lead to the development of novel antibiotics for their treatment. Due to the challenging synthesis of the precursor thioester, this malonyl-CoA analogue could not be prepared. Chapter 4 reports the synthesis of α,α,β-trifluoro cyclopropane-CoA and was found to be a poor inhibitor of citrate synthase (Kᵢ = 65.2 µM ). However, this compound has potential to be a covalent inhibitor of citrate synthase and other enzymes such as malate synthase, thus future investigations will be carried out to this purpose. Furthermore, chapter 4 reports the attempted synthesis of an α,α-difluoroethyl thioether-CoA as an acetyl-CoA analogue. This compound bears two electronegative fluorine atoms, thus it could interact electrostatically with the active site residues of citrate synthase through hydrogen bonds, leading to its inhibition. Unfortunately, due to the instability of the difluoro moiety under the enzymatic reaction conditions, this was not converted to the corresponding acetyl-CoA analogue.

description: We have carried out fully relativistic full-potential, spin-polarized, all-electron density-functional calculations for straight, monatomic nanowires of the 5d transition and noble metals Os, Ir, Pt and Au. We find that, of these metal nanowires, Os and Pt have mean-field magnetic moments for values of the bond length at equilibrium. In the case of Au and Ir, the wires need to be slightly stretched in order to spin polarize. An analysis of the band structures of the wires indicate that the superparamagnetic state that our calculations suggest will affect the conductance through the wires -- though not by a large amount -- at least in the absence of magnetic domain walls. It should thus lead to a characteristic temperature- and field dependent conductance, and may also cause a significant spin polarization of the transmitted current.

description: This paper reviews habitability conditions for a terrestrial planet from the point of view of geosciences. It addresses how interactions between the interior of a planet or a moon and its atmosphere and surface (including hydrosphere and biosphere) can affect habitability of the celestial body. It does not consider in detail the role of the central star but focusses more on surface conditions capable of sustaining life. We deal with fundamental issues of planetary habitability, i.e. the environmental conditions capable of sustaining life, and the above-mentioned interactions can affect the habitability of the celestial body. We address some hotly debated questions including: - How do core and mantle affect the evolution and habitability of planets? - What are the consequences of mantle overturn on the evolution of the interior and atmosphere? - What is the role of the global carbon and water cycles? - What influence do comet and asteroid impacts exert on the evolution of the planet? - How does life interact with the evolution of the Earth's geosphere and atmosphere? - How can knowledge of the solar system geophysics and habitability be applied to exoplanets? In addition, we address the identification of preserved life tracers in the context of the interaction of life with planetary evolution.

description: Positive muon spin rotation and relaxation spectroscopy is a well established experimental technique for studying materials. It provides a local probe that generally complements scattering techniques in the study of magnetic systems and represents a valuable alternative for materials that display strong incoherent scattering or neutron absorption. Computational methods can effectively quantify the microscopic interactions underlying the experimentally observed signal, thus substantially boosting the predictive power of this technique. Here, we present an efficient set of algorithms and workflows devoted to the automation of this task. In particular, we adopt the so-called DFT+μ procedure, where the system is characterised in the density functional theory (DFT) framework with the muon modeled as a hydrogen impurity. We devise an automated strategy to obtain candidate muon stopping sites, their dipolar interaction with the nuclei, and hyperfine interactions with the electronic ground state. We validate the implementation on well-studied compounds, showing the effectiveness of our protocol in terms of accuracy and simplicity of use

description: We study the simplest class of Bekenstein-type, varying $α$ models, in which the two available free functions (potential and gauge kinetic function) are Taylor-expanded up to linear order. Any realistic model of this type reduces to a model in this class for a certain time interval around the present day. Nevertheless, we show that no such model is consistent with all existing observational results. We discuss possible implications of these findings, and in particular clarify the ambiguous statement (often found in the literature) that ``the Webb results are inconsistent with Oklo''.

description: Chirality refers to a geometric phenomenon in which objects are not superimposable on their mirror image. Structures made of nano-scale chiral elements can display chiroptical effects, such as dichroism for left- and right- handed circularly polarized light, which makes them of high interest for applications ranging from quantum information processing and quantum optics to circular dichroism spectroscopy and molecular recognition. At the same time, strong effects have been challenging to achieve even in synthetic optical media and chiroptical effects for light with normal incidence has been speculated to be prohibited in lossless, thin, quasi-two-dimensional structures. Here, we report on our experimental realization of a giant chiroptical effect in a thin monolithic photonic crystal mirror. Unlike conventional mirrors, our structure selectively reflects only one spin state of light, while preserving its handedness, with a near unity level of circular dichroism. The operational principle of the photonic-crystal mirror relies on Guided Mode Resonance (GMR) with simultaneous excitation of leaky TE and TM Bloch modes in the photonic crystal slab. Such modes are not reliant on the suppression of their radiative losses through the long-range destructive interference and even small areas of the photonic-crystal exhibit robust circular dichroism. Despite its simplicity, the mirror strongly surpasses the performance of earlier reported structures and, contrary to a prevailed notion, demonstrates that near unity reflectivity contrast for the opposite helicities is achievable in a quasi-two-dimensional structure.

We investigate the dependence of the b quark, B meson and decay muon differential cross sections on the different forms of unintegrated gluon distributions. The analysis also covers the azimuthal correlations between the b and \bar b quarks and their decay muons. Our theoretical results agree well with recent data taken by the D0 and CDF collaborations at Tevatron. Finally, we present our predictions for muon-muon and muon-jet cross sections at the Tevatron and CERN LHC conditions.

description: Research of gaseous hydrogen atmospheric discharge, mixing, dispersion and explosion of hydrogen cloud is important for resolution of safety issues in those industries, which are related to production, storage and use of hydrogen. High fire risk of these processes is bound up with special properties of gaseous hydrogen: high burning rate, easy inflammability, wide concentration limits of flame distribution and high diffusion coefficient. The three-dimensional mathematical model of outflow of gaseous hydrogen, mixing of it with air and further atmospheric distribution of mixture in the opened space with complex relief, and also in the enclosed space with the forced (or natural) ventilation. The flow under review is described on the basis of spatial differential Euler equations, which allow taking into account the gases mixing and convection basic effects. The change of admixture concentration was determined by means of mixture component transfer law taking into account the rate of the turbulent diffusion. Developed numerical solution algorithm of basic conservation equations uses Godunov's disintegration scheme of arbitrary parameters breakup. On the basis of mathematical model the computer system of engineering analysis of gaseous hydrogen outflow, mixing and dispersion gas-dynamic processes was created, which allows forecasting the admixture concentration distribution in time and space. The computational solution of the following practical tasks was obtained: ­ Hydrogen-air mixture formation and subsequent dispersion in industrial buildings with natural and forced ventilation in the presence of equipment leakage; ­ Outflow, mixing and dispersion of hydrogen-air mixture in space with complex relief after the instantaneous emergency atmospheric emission; ­ Hydrogen-air mixture explosion in the open space with complex relief. Comparison of computational results with the published experimental data on the rapid discharge of large amount of liquid hydrogen was conducted. The features of hydrogen explosion and dispersion in mid air were analysed. They are bound up with special properties of gaseous hydrogen: its low density and high diffusion coefficient, high speed reaction with oxygen, high burning rate, easy inflammability, wide concentration limits of flame distribution in diffusive and detonation the modes.

description: The French inventor Stanislas Sorel is well known for his invention of a commercially viable process to protect iron from corrosion using hot dip galvanising. It is less well known that Sorel also engaged in wider paint research, developing quick-drying zinc-white paint as well as a magnesium-based cement and paint. In this article we examine the history of Sorel’s work on zinc-based paints, demonstrating his role as innovator and inventor. During the mid-nineteenth century zinc-white gained widespread use as a safer alternative for house paint which up to then commonly relied on toxic white lead as a pigment. While Edme Jean Leclaire is commonly credited as having been the first to overcome the difficulties of mixing zinc oxide with oil in 1835, the research described in this article demonstrates that Sorel’s original metallic zinc paint preceded, and influenced Leclaire’s paints.

description: The world’s biggest killer is ischemic heart disease, responsible for 16% of the world’s total deaths. Since 2000, the largest increase in deaths has been for this disease, rising by more than 2 million to 8.9 million deaths in 2019. In recent years, many studies have shown that hydrogen has therapeutic and preventive effects in various human and animal disease models. In this study, we investigated the possible antioxidant effects of molecular hydrogen in erythrocytes and blood plasma in rats with the experimentally simulated chronic heart failure. We estimated the intensity of lipid peroxidation processes by the contents of diene and triene conjugates, Schiff bases, malonic dialdehyde, catalase activity. The results from this study suggest that inhalation of 2% molecular hydrogen leads to a decrease in pro-oxidant and an increase in antioxidant parameters. The results of this study provide the basic data for the mechanism research and application of molecular hydrogen in the future.

description: Carbon nanotube (CNT) in vivo inhalation studies are increasingly providing estimates of the quantity of material deposited in the lung, generally estimated using standard formulae and pulmonary deposition models. These models have typically been developed and validated using data from studies using sphere-like particles. Given the importance of particle morphology to pulmonary deposition, the appropriateness of such an approach was explored to identify any potential limitations. Aerosolized CNT particles typically form ‘fiber-like’ and/or ‘broadly spherical’ agglomerates. A review of currently used deposition models indicates that none have been directly validated against results for CNT, however, models for spherical particles have been extensively validated against a wide range of particle sizes and materials and are thus expected to provide reasonable estimates for most ‘broadly spherical’ CNT particles, although experimental confirmation of this would be of benefit, especially given their low density. The validation of fiber deposition models is significantly less extensive and, in general, focused on larger particles, e.g. asbestos. This raises concerns about the accuracy of deposition estimates for ‘fiber-like’ CNT particles and recommendations are made for future research to address this. An appreciation of the uncertainties on CNT deposition estimates is important for their interpretation and thus it is recommended that model sensitivity and uncertainty assessments be undertaken. Issues surrounding the measurement and derivation of model input data are also addressed, including instrument responses and particle density assessment options. Recommendations are also made for aerosol characterization to ‘future-proof’ CNT inhalation studies regarding advances in deposition modeling and toxicological understanding.

description: Photodynamic therapy (PDT) is a promising approach in the treatment of various tumors. The presence of three essential components: a photosensitizer, a light source and oxygen is required for generating reactive oxygen species and subsequent tumor destruction. In this study, we investigated the cell death pathway induced by Photodithazine (PD) mediated photodynamic therapy (PD-PDT). We found that PD localizes in the endoplasmic reticulum and Golgi apparatus of cancer cells. Upon irradiation at 20 J/cm2, PD induced death of tumor cells at concentrations exceeding 100 nM. Based on dying cell morphology, exposure of phosphatidylserine to the cell surface, presence of phosphorylated form of mixed lineage kinase domain like pseudokinase (pMLKL) and protective action of pan-caspase inhibitor and inhibitor of receptor-interacting protein kinase 1 (RIPK1), we hypothesize that Photodithazine forces cells to enter mixed-type cell death with features of apoptosis and necroptosis.

description: CuO in the form of micro- and nano-sized colloidal particles enters the human body from the environment. The aim of the study is the identification of morphological changes in rat liver tissues during chronic oral intake of micro- and nanosized CuO by image analysis. The experiments were performed on 45 male Wistar rats (3 groups: experimental (nanosized CuO); comparison (micro-sized CuO); control (water without CuO)). Suspensions CuO were administered to the rats orally once a day. Quantitative morphological parameters were determined by pathomorphological examination and image analysis using the method of constructing Voronoi diagrams (the ratio of cells of various shapes); average cell area; the average size of the cell perimeter and the number of cells per unit area. As a result of the analysis by the constructing Voronoi diagrams, was found that the main part of the model cells corresponding to hepatocytes has the shape of a hexagon. In the control group, their share is 35.89%, in the experience group – 29.09%, and in the comparison group – 30.59%. The density of cells’ distribution in the comparison group is 7 times higher than in the control group; in the experimental group, the same indicator is 4 times higher than in the control group. Collectively, the characteristics of morphological changes in liver tissue indicate greater toxicity of nano-sized copper oxide compared to its micro-sized analogue.

description: Deep learning (DL) is a powerful tool in computational imaging for many applications. A common strategy is to reconstruct a preliminary image as the input of a neural network to achieve an optimized image. Usually, the preliminary image is acquired with the prior knowledge of the imaging model. One outstanding challenge, however, is the degree to which the actual imaging model deviates from the assumed model. Model mismatches degrade the quality of the preliminary image and therefore affect the DL predictions. Another main challenge is that since most imaging inverse problems are ill-posed and the networks are over-parameterized, DL networks have flexibility to extract features from the data that are not directly related to the imaging model. To solve these challenges, a two-step-training DL (TST-DL) framework is proposed for real-time computational imaging without physics priors. First, a single fully-connected layer (FCL) is trained to directly learn the model. Then, this FCL is fixed and concatenated with an un-trained U-Net architecture for a second-step training to improve the output image fidelity, resulting in four main advantages. First, it does not rely on an accurate representation of the imaging model since the model is directly learned. Second, real-time imaging can be achieved. Third, the TST-DL network is trained in the desired direction and the predictions are improved since the first step is constrained to learn the model and the second step improves the result by learning the optimal regularizer. Fourth, the approach accommodates any size and dimensionality of data. We demonstrate this framework using a linear single-pixel camera imaging model. The results are quantitatively compared with those from other DL frameworks and model-based iterative optimization approaches. We further extend this concept to nonlinear models in the application of image de-autocorrelation.

description: We have explored the features of PPARγ2 gene alleles expression in elderly patients with comorbid conditions such as obesity and coronary artery disease. 140 patients of both sexes (54.3% men and 45.7% women) aged 60-89 were examined. The main group included 70 pts with CHD; the control group included 70 pts without CHD. Pro12 allele carrier state in the main group was 85%, and Ala12 allele carrier state – 15%. Pro12Ala and Ala12Ala genotypes, Ala12 allele were detected more often in patients with coronary artery disease than in the control group (p = 0.0008 and p = 0.0003, respectively). Pro12Ala genotypes (OR = 2.02, CI = 1.28–3.19, p = 0.003) and Ala12Ala (OR = 2.002, CI = 1.32–3.04, p = 0.0006) of Ala12 gene PPARγ2 carrier state increases the risk of CHD developing by 2 times. It was confirmed that nuclear PPARs are capable of controlling development, differentiation, metabolic homeostasis and reproduction. The role of various genotypes of the PPARγ2 gene in the regulation of lipid metabolism and angiogenesis in comorbid conditions in elderly patients may help to identify new methods of their treatment.

description: Using a refractive index matching method, we investigate the trajectories of particles in a three dimensional granular packing submitted to cyclic shear deformation. The particle motion observed during compaction is not diffusive but exhibits transient cage effect, similar to the one observed in colloidal glasses. We precisely study the statistics of the step size between two successive cycles and observe that it is proportional to the shear amplitude. The link between the microscopic observations and the macroscopic evolution of the volume fraction during compaction is discussed.

description: The problem of dynamic estimation of all parameters of a model representing chaotic and hyperchaotic systems using information from a scalar measured output is solved. The variational calculus based method is robust in the presence of noise, enables online estimation of the parameters and is also able to rapidly track changes in operating parameters of the experimental system. The method is demonstrated using the Lorenz, Rossler chaos and hyperchaos models. Its possible application in decoding communications using chaos is discussed.

Self-force from conical singularity, without renormalization

description: We develop an approach to calculate the self-force on a charged particle held in place in a curved spacetime, in which the particle is attached to a massless string and the force is measured by the string's tension. The calculation is based on the Weyl class of static and axially symmetric spacetimes, and the presence of the string is manifested by a conical singularity; the tension is proportional to the angular deficit. A remarkable and appealing aspect of this approach is that the calculation of the self-force requires no renormalization of the particle's field. This is in contract with traditional methods, which incorporate a careful and elaborate subtraction of the singular part of the field. We implement the approach in a number of different situations. First, we examine the case of an electric charge in Schwarzschild spacetime, and recover the classic Smith-Will force in addition to a purely gravitational contribution to the self-force. Second, we turn to the case of electric and magnetic dipoles in Schwarzschild spacetime, and correct expressions for the self-force previously obtained in the literature. Third, we replace the electric charge by a scalar charge, and recover Wiseman's no-force result, which we generalize to a scalar dipole. And fourth, we calculate the force exerted on extended bodies such as Schwarzschild black holes and Janis-Newman-Winicour objects, which describe scalarized naked singularities.

The targum (1973:Feb. 1 - 1973:Feb. 28)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1973

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

Improved Variational Analysis of Deconfinement in SU(N) Gauge Theory

description: A variational analysis of the pure SU(N) gauge theory in 3+1 dimensions at finite temperature is performed, extending the work of Kogan, Kovner and Milhano in hep-ph/0208053 . A de-confining phase transition is found at a temperature of 470 MeV, somewhat higher than lattice estimates. This value is however rather sensitive, for reasons which are discussed. A more robust quantity is the ratio of the transition temperature to the lightest glueball mass in the model. This is 0.18, in agreement with the lattice estimate for SU(3) to two significant figures. Ways of further improving the calculation are discussed.

description: A result of Watanabe and Yoshida says that an unmixed local ring of positive characteristic is regular if and only if its Hilbert-Kunz multiplicity is one. We show that, for fixed $p$ (characteristic) and $d$ (dimension), there exist a number $ε(d,p) > 0$ such that any nonregular unmixed ring $R$ has Hilbert-Kunz multiplicity at least $1+ε(d,p)$. We also show that local rings with sufficiently small Hilbert-Kunz multiplicity are Cohen-Macaulay and $F$-rational.

description: Within the framework of the dipole factorisation, we use a recent collinearly-improved version of the Balitsky-Kovchegov equation to fit the HERA data for inclusive deep inelastic scattering at small Bjorken $x$. The equation includes an all-order resummation of double and single transverse logarithms and running coupling corrections. Compared to similar equations previously proposed in the literature, this work makes a direct use of Bjorken $x$ as the rapidity scale for the evolution variable. We obtain excellent fits for reasonable values for the four fit parameters. We find that the fit quality improves when including resummation effects and a physically-motivated initial condition. In particular, the resummation of the DGLAP-like single transverse logarithms has a sizeable impact and allows one to extend the fit up to relatively large photon virtuality $Q^2$.

description: Currently, radionuclide therapy of tumors using sources of alpha and beta radiation is actively developing. However, the radiosensitivity of tumor cells has been studied mainly using acute gamma radiation. In this regard, studies aimed at determining the ranges of radiosensitivity of cells of various origins in relation to beta-emission radionuclides are gaining relevance. The study was carried out on A431, CHO and SK-BR-3 cell lines using beta-emission sealed sources Sr-90+Y-90. Cell viability was assessed via MTT-assay. Dose dependences were obtained for irradiating cells with a beta source: the LD50 range was from 17 to 19 Gy, and LD37 was from 24 to 36 Gy. It was shown that at the same dose of radiation, the percentage of viable cells relative to the control of 72 hours after irradiation is significantly less than after 24 hours. The revealed LD50 values for tumor cells under chronic beta-irradiation are higher than with acute gamma-irradiation, which should be considered when selecting doses during the development of potential radiopharmaceutical treatment. Decreased cell viability in response to beta radiation is due to both cytotoxic and cytostatic manifestations.
