PRECISE AND ACCURATE MEASUREMENTS OF COSMOLOGICAL PARAMETERS FROM GALAXY CLUSTERING AND MOTIONS

description: Measurements of the growth rate of large scale structure in the Universe are crucial to pinpoint the origin of cosmic acceleration, distinguishing whether it requires the existence of "dark energy", or rather a modification of General Relativity. Galaxy clustering measured in redshift space contains the imprint of such growth in the form of a measurable large-scale anisotropy. These redshift-space distortions (RSD) are produced by the coherent peculiar velocity flows towards overdensities, which add to the cosmological redshift. The present Thesis is focused on improving our ability to extract measurements of the growth rate from galaxy redshift surveys. To this end, I have first tested the performances of standard estimators, using numerical simulations. I find that the traditional dispersion model is affected by a systematic error larger than the statistical ones expected from current/future galaxy surveys. To improve on this, I have then developed a novel description of the line-of-sight pairwise velocity distribution, which is a crucial ingredient in modelling RSD. Using a principal component analysis, I find that redshift-space clustering on all scales can be described by a minimum set of four eigenfunctions of the velocity distributions. Inspired by these findings, I have then proposed an alternative parametrization in which the link to the underlying physics is more explicit. This is obtained by describing the overall velocity distribution as a superposition of local Gaussian velocity distributions, whose mean and standard deviation are, in turn, distributed according to a bivariate Gaussian. Tests of this model against simulations show that it is general enough to correctly describe RSD on all scales, capturing surprisingly well the dynamics of the galaxy flow. This opens a new horizon for the development of a complete model of redshift-space distortions based on the formally exact "streaming model" approach.

description: Age-related cognitive impairment is generally characterized by gradual memory loss and decision-making difficulties. The aim of this study is to investigate multi level support and suggest relevant helping means for the elderly with mild cognitive impairment as well as their caregivers as the primary end-users. This work reports preliminary results on an intelligent assistive system, achieved through the integration of Internet of Things, augmented reality, and adaptive fuzzy decision-making methods. The proposed system operates in different modes, including automated and semi-automated modes. The former helps the user complete their daily life activities by showing augmented reality messages or making automatic changes; while the latter allows manual changes after the real-time assessment of the user's cognitive state based on the augmented reality serious game score. We have also evaluated the accuracy of the serious game score with 37 elderly participants and compared it with users' paper-based cognitive test results. We further noted that there is an acceptable correlation between the paper-based test and users' serious game scores. Moreover, we observed that the system response in the semi-automated mode causes less data loss compared with the automated mode, as the number of active devices decreases.

description: The O17(p,γ)F18 reaction sensitively influences hydrogen burning nucleosynthesis in a number of stellar sites, including classical novae. These thermonuclear explosions, taking place in close binary star systems, produce peak temperatures in the range of T=100-400 MK. Recent results indicate that the thermonuclear rates for this reaction in this particular temperature range are dominated by the direct capture process. We report on the measurement of the O17(p,γ)F18 cross section between the narrow resonances at Erlab=193 and 519keV, where the S factor is expected to vary smoothly with energy. We extract the direct capture contribution from the total cross section and demonstrate that earlier data are inconsistent with our results.

description: Anthocyanins (ACN) bioavailability and metabolism were not well established. Moreover, ACN are labile compounds and deteriorate during storage. Thus, the degradation kinetics of ACN contained in wild blueberry (WB) powder stored at 25, 42, 60 and 80 �C for 49 days and total antioxidant activity (TAA) were evaluated. Then, we investigated WB ACN adsorption, metabolism, distribution in the plasma, liver, brain, and their excretion in urine and feces in rats fed a WB-enriched diet (24�5 mg/day of ACN) for 4 and 8 weeks. At last, we evaluated ACN transformation by human and rat microflora from stomach, small intestine and colon. Anthocyanins in WB were 1.8�0.1 mg/100 mg powder. The product maintains the content of ACN and TAA longer (up to 130 days) at 25�C; however, storage at 4 �C represents the best way to delay decay. Anthocyanin profile in biological sample significantly increased in urine and not in feces after 8 weeks on the WB diet compared to that in 4 weeks. No ACNs were detected in the controls. ACN metabolites were detected in the plasma, urine, feces, and tissues, but the urinary excretion of hippuric acid increased significantly after 4 and 8 weeks of WB consumption. Thus, ACN are metabolized by the intestinal microflora to respective phenyl-alkyl acids, which can be further metabolized to benzoic acid. In conclusion, ACN are bioavailable in rats, and the extent of their metabolism and excretion is based on diet duration. The colon bacteria showed the highest catabolic activity against ACN, indeed about 84% degradation in the first six hours of incubation. The amount of the formed phenolic acid reached up to a maximum of 40 % of the parent compound, suggesting the occurrence of ACNs degradation pathways not yet identified.

description: Multi-band photometric observations of eleven totally eclipsing contact binaries were carried out. Applying the Wilson-Devinney program, photometric solutions were obtained. There are two W-subtype systems, which are CRTS J133031.1+161202 and CRTS J154254.0+324652, and the rest systems are A-subtype systems. CRTS J154254.0+324652 has the highest fill-out factor with 94.3$\%$, and the lowest object is CRTS J155009.2+493639 with only 18.9$\%$. The mass ratios of the eleven systems are all less than 0.1, which means that they are extremely low mass ratio binary systems. We performed period variation investigation and found that the orbital periods of three systems decrease slowly, which may be caused by the angular momentum loss, and of six systems increase slowly, which indicates that the materials may transfer from the secondary component to the primary component. LAMOST low$-$resolution spectra of four objects were analyzed, and using the spectral subtraction technique, H$α$ emission line was detected, which means that the four objects exhibit chromospheric activity. In order to understand their evolutionary status, the mass-luminosity and mass-radius diagrams were plotted. The two diagrams indicate that the primary component is in the main sequence evolution stage, and the secondary component is above TAMS, indicating that they are over-luminous. To determine whether the eleven systems are in stable state, the ratio of spin angular momentum to orbital angular momentum ($J_{s}/J_{o}$) and the instability parameters were calculated, and we argued that CRTS J234634.7+222824 is on the verge of a merger.

description: In a recent paper (A. Mitsopoulos and M. Tsamparlis, J. Geom. Phys. 170, 104383, 2021), a general theorem is given which provides an algorithmic method for the computation of first integrals (FIs) of autonomous dynamical systems in terms of the symmetries of the kinetic metric defined by the dynamical equations of the system. In the present work, we apply this theorem to compute the cubic FIs of autonomous conservative Newtonian dynamical systems with two degrees of freedom. We show that the known results on this topic, which have been obtained by means of various different methods, and additional ones derived in this work can be obtained by the single algorithmic method provided by this theorem. The results are collected in four Tables which can be used as an updated reference of this type of integrable and superintegrable potentials. The results we find are for special values of free parameters; therefore, using the methods developed here, other researchers by different suitable choice of the parameters will be able to find new integrable and superintegrable potentials.

description: A number of examples for direct measurements in nuclear astrophysics are given in order to address several important issues. First, recent results for the 16O(p,g)17F reaction are discussed and it is shown how an improvement in reaction rate precision allows for significantly improved astrophysical predictions in connection with massive AGB stars. Second, we discuss improved experimental techniques for measuring astrophysically important (p,γ), (α,γ), (p,α) and (α,n) reactions. Emphasis is placed on the application of coincidence techniques in order to substantially reduce unwanted background signals. Third, the question of how a measured quantity and its associated uncertainty influences the derived reaction rate is explored. Recent advances employing the Monte Carlo method for estimating reaction rates are presented. The new reaction rates will allow for nucleosynthesis studies that were previously not feasible.

description: The complex circumstellar ejecta of highly evolved, cool hypergiants are indicative of multiple, asymmetric mass loss events. To explore whether such episodic, non-isotropic mass loss may be driven by surface magnetic activity, we have observed the archetypical cool hypergiant VY CMa with the XMM-Newton X-ray satellite observatory. The hypergiant itself is not detected in these observations. From the upper limit on the X-ray flux from VY CMa at the time of our observations ($F_{X,UL}~\approx~8\times10^{-14} {\rm~erg~cm}^{-2} {\rm~s}^{-1}$, corresponding to $\log~L_X/L_{bol}\leq-8$), we estimate an average surface magnetic field strength $fB \leq 2\times10^{-3}$~G (where $f$ is the filling factor of magnetically active surface regions). These X-ray results for VY CMa represent the most stringent constraints to date on the magnetic field strength near the surface of a hypergiant. VY CMa's mass loss is episodic and may have been in a state of low surface magnetic activity during the XMM observations. The XMM observations also yield detections of more than 100 X-ray sources within $\sim$15$^{\prime}$ of VY CMa, roughly 50 of which have near-infrared counterparts. Analysis of X-ray hardness ratios and IR colors indicates that some of these field sources may be young, late-type stars associated with VY CMa, its adjacent molecular cloud complex, and the young cluster NGC 2362. Further study of the VY CMa field is warranted, given the potential to ascertain the evolutionary timescale of this enigmatic, massive star.

description: We investigated Cu/ZnO model catalysts for methanol synthesis to obtain an atomistic picture of activation and deactivation processes under in situ oxidizing and reducing conditions. We have investigated Cu nanoparticles with different shapes and aspect ratios grown epitaxially on basal and vicinal ZnO surfaces at elevated gas pressures by high energy grazing incidence X-ray diffraction and ambient pressure X-ray photoelectron spectroscopy (AP-XPS). We find that the Cu nanoparticles are fully oxidized to Cu$_2$O under atmospheric conditions at room temperature. During oxidation, they maintain their epitaxy on basal ZnO (000-1) surfaces, whereas on the vicinal ZnO (10-14) surface, the nanoparticles undergo a coherent tilt. We find that the oxidation process is fully reversible under H2 flow at 500 K, resulting in predominantly well-aligned nanoparticles on the basal surfaces, whereas a random orientation is preferred for the (10-14) surface. Under CO$_2$ flow, no diffraction signal from the nanoparticles is detected, pointing to their completely disordered state. The AP-XPS results are in line with the formation of CuO. The analys is of the substrate crystal truncation rods evidences the stability of basal ZnO surfaces under all gas conditions. No proof for Cu-Zn alloy formation is found. Scanning electron microscopy images show that massive mass transport has set in, leading to the formation of larger agglomerates, which is detrimental to the catalyst’s performance.

description: The nuclear structure of 19Ne near the proton threshold is of interest for understanding the rates of proton-induced reactions on 18F in novae. Analogues for several states in the mirror nucleus 19F have not yet been identified in 19Ne indicating the level structure of 19Ne in this region is incomplete. The 18F(d,n)19Ne and 18F(d, p)19F reactions have been measured simultaneously at Ec.m. = 14.9 MeV. The experiments were performed at the Holifield Radioactive Ion Beam Facility (HRIBF) of Oak Ridge National Laboratory (ORNL) by bombarding a 720-μg/cm2 CD2 target with a radioactive 18F beam. The 19Ne states of interest near the proton threshold decay by breakup into a and 15O particles. These decay products were detected in coincidence with position-sensitive E-ΔE silicon telescopes. The α and 15N particles from the break up of the mirror nucleus 19F were also measured with these detectors. Particle identification, coincidence, and Q-value requirements enable us to distinguish the reaction of interest from other reactions. The reconstruction of relative energy of the detected particles reveals the excited states of 19Ne and 19F which are populated. The neutron (proton) angular distributions for states in 19Ne (19F) were extracted using momentum conservation. The observed states in 19Ne and 19F will be presented.
Distal and non-symmetrical crack nucleation in delamination of plates via dimensionally-reduced peridynamics

description: Exploiting the framework of peridynamics, a dimensionally-reduced plate formulation is developed that allows for the through-thickness nucleation and growth of fracture surfaces, enabling the treatment of delamination in a lower-dimensional model. Delamination fracture nucleation and propagation are treated by choosing the kinematics to be composed of an absolutely continuous part and a zone where jumps in the displacements are allowed. This assumption allows the explicit derivation of the dimensionally-reduced elastic energy, which shows a hierarchy of terms characterising the stored energy in the plane element. An interpretation of the various terms of the reduced energy is shown by means of the most straightforward paradigm of bond-based peridynamics. A striking feature of the reduced energy is that, despite the small-displacement assumption, there is a coupling between the membrane and bending terms. Semi-analytical solutions for simplified settings are obtained through a minimization procedure, and a range of nonstandard behaviours such as \textit{distal} crack nucleation and curved crack path are captured by the model. Finally, convergence of the proposed peridynamic reduced model to a local elastic theory for vanishing nonlocal lengthscale is determined, giving a local cohesive model for fracture.

description: The supersolar abundances of volatiles observed in giant planets suggest that a compositional gradient was present at the time of their formation in the protosolar nebula. To explain this gradient, several studies have investigated the radial transport of trace species and the effect of icelines on the abundance profiles of solids and vapors formed in the disk. However, these models only consider the presence of solids in the forms of pure condensates or amorphous ice during the evolution of the protosolar nebula. They usually neglect the possible crystallization and destabilization of clathrates, along with the resulting interplay between the abundance of water and those of these crystalline forms. This study is aimed at pushing this kind of investigation further by considering all possible solid phases together in the protosolar nebula: pure condensates, amorphous ice, and clathrates. To this end, we used a one-dimensional (1D) protoplanetary disk model coupled with modules describing the evolution of trace species in the vapor phase, as well as the dynamics of dust and pebbles. Eleven key species are considered here, including H$_2$O, CO, CO$_2$, CH$_4$, H$_2$S, N$_2$, NH$_3$, Ar, Kr, Xe, and PH$_3$. Two sets of initial conditions are explored for the protosolar nebula. In a first scenario, the disk is initially filled with icy grains in the forms of pure condensates. In this case, we show that clathrates can crystallize and form enrichment peaks up to about ten times the initial abundances at their crystallization lines. In a second scenario, the volatiles were delivered to the protosolar nebula in the forms of amorphous grains. In this case, the presence of clathrates is not possible because there is no available crystalline water ice in their formation region. Enrichment peaks of pure condensates also form beyond the snowline up to about seven times the initial abundances.

description: Long range antiferromagnetic (AFM) ordering of Ni spins in Ni2NbBO6 has been studied with single crystal from spin susceptibility measurement and comparedwith the ab initio calculation results consistently. Below TN = 23.5 K, the S = 1 spins align along the a direction for edge-shared NiO6 octahedra which form crystallographic armchair chains along the b direction. The isothermal magnetization M(H) below TN shows spin-flop transition for magnetic field above 36 kOe along the a axis,which indicates the spin anisotropy is along the a direction. The electronic and magnetic structures of Ni2NbBO6 have also been explored theoretically using density functional theory with generalized gradient approximation plus on-site Coulomb interaction (U). These calculations support the experimentally observed antiferromagnetism of Ni2NbBO6. In particular, the long range AFM ordering below TN can be dissected into armchair chains which consists of S = 1 dimers of J2 = 2.43 meV with ferromagnetic (FM) intrachain and interchain couplings of size half |J2|.

description: Plant viruses are near-ubiquitous across natural and managed ecosystems and are known to cause significant economic damage, influence host phenotypes and modulate host-insect and microbial interactions. Metagenomic surveys of plants have recently revealed the enormous diversity of viruses they carry. Yet, this new knowledge has predominantly come from cultivated species - a small and biased subset of the plant kingdom. Next-generation sequencing technology has led to an explosion in open-source transcriptomic data which is an untapped resource for virus discovery. Here, I surveyed the transcriptomes of 960 plant species to quantify the diversity and abundance of plant viruses across 422 plant families and multiple functional groupings (i.e. dispersal syndromes, fruit types, growth forms, longevity classes, and woodiness types). In total, 3,673 plant virus transcripts were found in 415 plant species across the plant kingdom. Virome composition was associated with plant growth form and phylogenetic lineage. Notably, high virus abundance is associated with plants with a climbing habit while ancient plant lineages (algae, gymnosperms) had significantly lower virus diversity compared to more recently evolved groups, like the basal eudicots. I identified 29 potentially novel viruses including the discovery of several single-stranded RNA virus families (i.e. Benyviridae, Tymoviridae and Secoviridae) for the first time in lower plants or algae highlighting that non-cultivated plants likely harbour a multitude of viruses, of which the vast majority are undescribed. With the knowledge generated herein, we can begin to resolve long-held questions about the origins and diversification of plant viruses.

description: A recently discovered resonance at 193 keV determines the thermonuclear rates of the O17 +p reactions at temperatures important for the nucleosynthesis in classical novae (T=0.1-0.4 GK). We report on a remeasurement of this resonance in the O17(p,α)N14 reaction by using a different kind of target compared to the previous study. Special emphasis is placed on Monte Carlo simulations of the experiment in order to better understand certain effects that have been disregarded previously. Our measured value of the resonance strength amounts to (ωγ)pα=(1.66±0.17)×10-3 eV, in agreement with the previously reported result. As a byproduct of our study, we find that the inhomogeneity of the foil placed in front of the α-particle detector determines the resolution in the pulse-height spectrum, and thus constrains the signal-to-noise ratio in searches of very weak (p,α) resonances.

We present two elementary proofs of this classical result which are independent of the holomorphic functional calculus. We also discuss the case of real Banach algebras. As applications, we obtain simple proofs that every invertible matrix over $\mathbb C$ has a logarithm and that every real matrix $M$ in $M_n(\mathbb R)$ with $\det M>0$ is a product of two real exponential matrices.

description: To solve the problems of reduced accuracy and prolonging convergence time of through-the-wall radar (TWR) human motion due to wall attenuation, multipath effect, and system interference, we propose a multilink auto-encoding neural network (TWR-MCAE) data augmentation method. Specifically, the TWR-MCAE algorithm is jointly constructed by a singular value decomposition (SVD)-based data preprocessing module, an improved coordinate attention module, a compressed sensing learnable iterative shrinkage threshold reconstruction algorithm (LISTA) module, and an adaptive weight module. The data preprocessing module achieves wall clutter, human motion features, and noise subspaces separation. The improved coordinate attention module achieves clutter and noise suppression. The LISTA module achieves human motion feature enhancement. The adaptive weight module learns the weights and fuses the three subspaces. The TWR-MCAE can suppress the low-rank characteristics of wall clutter and enhance the sparsity characteristics in human motion at the same time. It can be linked before the classification step to improve the feature extraction capability without adding other prior knowledge or recollecting more data. Experiments show that the proposed algorithm gets a better peak signal-to-noise ratio (PSNR), which increases the recognition accuracy and speeds up the training process of the back-end classifiers.

description: The Gamow peak represents one of the most important concepts in the study of thermonuclear reactions in stars. It is widely used in order to determine, at a given plasma temperature, the effective stellar energy region in which most charged-particle induced nuclear reactions occur. It is of importance in the design of nuclear astrophysics measurements, including those involving radioactive ion beams, and for the determination of stellar reaction rates. We demonstrate that the Gamow peak concept breaks down under certain conditions if a nuclear reaction proceeds through narrow resonances at elevated temperatures. It is shown that an effective stellar energy window does indeed exist in which most thermonuclear reactions take place at a given temperature, but that this energy window can differ significantly from the commonly used Gamow peak. We expect that these findings are especially important for thermonuclear reactions in the advanced burning stages of massive stars and in explosive stellar environments.

description: A new measurement of the β-delayed α decay of N16 has been performed using a set of high efficiency ionization chambers. Sources were made by implantation of a N16 beam, yielding very clean α spectra down to energies as low as 400 keV. Our data are in good agreement with earlier results. For the S factor SE1, we obtain a value of 74±21keVb. In spite of improvements in the measurement, the error in SE1 remains relatively large because of the correlations among the fit parameters and the uncertainties inherent to the extrapolation.

description: In this study, a series of fourteen Cu (II), Zn (II), Ni (II) and Ag (I) complexes containing bis-benzimidazole derivatives were successfully designed and synthesized from 2-(1H-benzimidazole-2-yl)-phenol derivatives and corresponding metal salt solutions. The compound structures were identified by FT-IR, 1H-NMR, powder X-ray diffraction and ESI-MS analyses, and the presence of the metal in the complexes was confirmed by ultraviolet-visible spectroscopy and ICP optical emission spectrometry. Electronic structure calculations were also carried out to describe the detailed structures in addition to the electronic absorption spectra of the ligands. The cytotoxic activity of the complexes was evaluated against three human cancer cell lines: lung (A549), breast (MDA-MB-231) and prostate (PC3) cancer cells. All complexes inhibited anti-proliferative cancer cells better than free ligands, especially Zn (II) and Ag (I) complexes, which are most sensitive to MDA-MB-231 cells. In addition, showing the growth inhibition of three cancer cell lines with IC50 < 10.4 µM, complexes C1, C3 and C14 could be considered potential multi-targeted anti-cancer agents.

description: In one of the most celebrated examples of the theory of universal critical phenomena, the phase transition to the superfluid state of $^{4}$He belongs to the same three dimensional $\mathrm{O}(2)$ universality class as the onset of ferromagnetism in a lattice of classical spins with $XY$ symmetry. Below the transition, the superfluid density $ρ_s$ and superfluid velocity $v_s$ increase as power laws of temperature described by a universal critical exponent constrained to be equal by scale invariance. As the dimensionality is reduced towards one dimension (1D), it is expected that enhanced thermal and quantum fluctuations preclude long-range order, thereby inhibiting superfluidity. We have measured the flow rate of liquid helium and deduced its superfluid velocity in a capillary flow experiment occurring in single $30~$nm long nanopores with radii ranging down from 20~nm to 3~nm. As the pore size is reduced towards the 1D limit, we observe: {\it i)} a suppression of the pressure dependence of the superfluid velocity; {\it ii)} a temperature dependence of $v_{s}$ that surprisingly can be well-fitted by a powerlaw with a single exponent over a broad range of temperatures; and {\it iii)} decreasing critical velocities as a function of radius for channel sizes below $R \simeq 20$~nm, in stark contrast with what is observed in micron sized channels. We interpret these deviations from bulk behaviour as signaling the crossover to a quasi-1D state whereby the size of a critical topological defect is cut off by the channel radius.

description: Atmospheres with a high C/O ratio are expected to contain an important quantity of hydrocarbons, including heavy molecules (with more than 2 carbon atoms). To study correctly these C-rich atmospheres, a chemical scheme adapted to this composition is necessary. We have implemented a chemical scheme that can describe the kinetics of species with up to 6 carbon atoms. This chemical scheme has been developed with specialists of combustion and validated through experiments on a wide range of T and P. This chemical network is available on the online database KIDA. We have created a grid of 12 models to explore different thermal profiles and C/O ratios. For each of them, we have compared the chemical composition determined with a C0-C2 chemical scheme (species with up to 2 carbon atoms) and with the C0-C6 scheme. We found no difference in the results obtained with the two schemes when photolyses are not included in the model, whatever the temperature of the atmosphere. In contrast, when there is photochemistry, differences can appear in the upper atmosphere. These differences are found for all the tested PT profiles in the case that the C/O ratio is above 1. When the C/O ratio of the atmosphere is solar, differences are only found at temperatures lower than 1000K. The differences linked to the use of different chemical schemes do not have important influence on the synthetic spectra. However, we have confirmed that C2H2 and HCN as possible tracers of warm C-rich atmospheres. The use of this new chemical scheme is mandatory to model atmospheres with a high C/O ratio and, in particular, if one is interested in studying in details the photochemistry. If one is just interested in the synthetic spectra, the use of a smaller scheme may be sufficient.

description: The CNO cycle is the main process for hydrogen burning in stars somewhat more massive than the Sun. The reaction cross sections at Gamow energies are typically in the femto to pico-barn range and are consequently very difficult to measure experimentally. The CNO reaction rates are based on extrapolations of experimental data from higher energies. We are developing a multi-channel R-matrix code (AZURE) to provide a new and more comprehensive tool for fitting experimental data and making extrapolations to lower energies in all reaction and scattering channels. The 14N(p,γ )15O reaction is the slowest reaction of the CNO cycle and thus it determines the energy production rate of CNO burning. Furthermore, this reaction plays an important role in the determination of Globular Cluster age, since the position of the turnoff point, at which the GC stars escape from the Main Sequence, is powered by the onset of the CNO burning, whose bottleneck is the 14N(p, γ )15O. We have made a reanalysis of the most recent experimental data on the ground state and the 6.18 MeV transitions. The ratio of the cross sections of the 15N(p, γ )16O and 15N(p,α)12C reactions determines how much catalytic material passes to higher CNO cycles and has an effect on the production of heavier elements, particularly 16O and 17O. Simultaneous analysis of both reactions for all channels suggests that the ratio σγ/σα is smaller than previously reported.
