description: Foreground emission and scattered light from interplanetary dust (IPD) particles and emission from Galactic stellar sources are the greatest obstacles for determining the cosmic infrared background (CIB) from diffuse sky measurements in the ~ 1 to 5 micron range. We use ground-based observational limits on the K-band intensity of the CIB in conjunction with skymaps obtained by the Diffuse Infrared Background Experiment (DIRBE) on the COBE satellite to reexamine the limits on the CIB at 1.25, 3.5, and 4.9 microns. Adopting a CIB intensity of 7.4 nW m-2 sr-1 at 2.2 microns, and using the 2.2 micron DIRBE skymap from which the emission from IPD cloud has been subtracted, we create a spatial template of the Galactic stellar contribution to the diffuse infrared sky. This template is then used to subtract the contribution of the diffuse Galactic stellar emission from the IPD-emission-subtracted DIRBE skymaps. The DIRBE 100 micron data are used to estimate the small contribution of emission from interstellar dust at 3.5 and 4.9 microns. Our method significantly reduces the errors associated with the subtraction of Galactic starlight, leaving only the IPD emission component as the primary obstacle for the detection of the CIB at these wavelengths. This analysis leads to a tentative detection of the CIB at 3.5 microns. The cosmological implications of these results are discussed in the paper.

Comparison of Optical, Radio, and Acoustical Detectors for Ultrahigh-Energy Neutrinos

description: For electromagnetic cascades induced by electron-neutrinos in South Pole ice, the effective volume per detector element (phototube, radio antenna, or acoustic transducer) as a function of cascade energy is estimated, taking absorption and scattering into account. A comparison of the three techniques shows that the optical technique is most effective for energies below ~0.5 PeV, that the radio technique shows promise of being the most effective for higher energies, and that the acoustic method is not competitive. Due to the great transparency of ice, the event rate of AGN ne-induced cascades is an order of magnitude greater than in water. For hard source spectra, the rate of Glashow resonance events may be much greater than the rate for non-resonant energies. The radio technique will be particularly useful in the study of Glashow events and in studies of sources with very hard energy spectra.

description: This paper introduces a novel method for solving the single-source localization problem, specifically addressing the case of trilateration. We formulate the problem as a weighted least-squares problem in the squared distances and demonstrate how suitable weights are chosen to accommodate different noise distributions. By transforming this formulation into an eigenvalue problem, we leverage existing eigensolvers to achieve a fast, numerically stable, and easily implemented solver. Furthermore, our theoretical analysis establishes that the globally optimal solution corresponds to the largest real eigenvalue, drawing parallels to the existing literature on the trust-region subproblem. Unlike previous works, we give special treatment to degenerate cases, where multiple and possibly infinitely many solutions exist. We provide a geometric interpretation of the solution sets and design the proposed method to handle these cases gracefully. Finally, we validate against a range of state-of-the-art methods using synthetic and real data, demonstrating how the proposed method is among the fastest and most numerically stable.

description: We explore the sensitivity of the nucleosynthesis of intermediate mass elements (28 < A < 80) in supernovae derived from massive stars to the nuclear reaction rates employed in the model. Two standard sources of reaction rate data (Woosley et al. 1978; and Thielemann et al. 1987) are employed in pairs of calculations that are otherwise identical. Both include as a common backbone the experimental reactions rates of Caughlan & Fowler (1988). Two stellar models are calculated for each of two main sequence masses: 15 and 25 solar masses. Each star is evolved from core hydrogen burning to a presupernova state carrying an appropriately large reaction network, then exploded using a piston near the edge of the iron core as described by Woosley & Weaver (1995). The final stellar yields from the models calculated with the two rate sets are compared and found to differ in most cases by less than a factor of two over the entire range of nuclei studied. Reasons for the major discrepancies are discussed in detail along with the physics underlying the two reaction rate sets employed. The nucleosynthesis results are relatively robust and less sensitive than might be expected to uncertainties in nuclear reaction rates, though they are sensitive to the stellar model employed.

On the Robustness and Scalability of Semidefinite Relaxation for Optimal Power Flow Problems

description: Semidefinite relaxation techniques have shown great promise for nonconvex optimal power flow problems. However, a number of independent numerical experiments have led to concerns about scalability and robustness of existing SDP solvers. To address these concerns, we investigate some numerical aspects of the problem and compare different state-of-the-art solvers. Our results demonstrate that semidefinite relaxations of large problem instances with on the order of 10,000 buses can be solved reliably and to reasonable accuracy within minutes. Furthermore, the semidefinite relaxation of a test case with 25,000 buses can be solved reliably within half an hour; the largest test case with 82,000 buses is solved within eight hours. We also compare the lower bound obtained via semidefinite relaxation to locally optimal solutions obtained with nonlinear optimization methods and calculate the optimality gap.

description: HST WFPC2 images in B (F450W) and I (F814W) have been obtained for three starburst (SB) and two post-starburst (PSB) galaxies in the Coma cluster, and for three such galaxies in the cluster DC2048-52. V (F555W) and I images for an additional PSB galaxy in Coma have been extracted from the archive. Seven of these galaxies were previously classified as E/S0 on the basis of ground-based images, one as Sa, and the other as an irregular. The HST images reveal these SB/PSB galaxies to be heterogeneous in morphology. Nevertheless a common theme is that many of them, especially the SB galaxies, tend to have centralized spiral structure that appears simply as a bright ``bulge''on ground-based images. In addition, while some PSB galaxies exhibit distinct spiral structure, on the whole they have smoother morphologies than the SB galaxies. The morphologies and luminosity profiles are generally consistent with substantial starbursts in the form of centralized spiral structure (the SB galaxies) which fade into smoother morphologies (the PSB galaxies), with lingering spectroscopic evidence for past central starbursts. An important point is that the PSB galaxies retain disks, i.e, they have not evolved into spheroidal systems.

description: We performed a series of theoretical transport studies on Y-branch electron waveguides which are embedded in mid-size armchair graphene nanoribbons (AGNRs). Non-equilibrium Greens function (NEGF) with different approximations of tight-binding (TB) Hamiltonian has been employed. Using the first nearest hopping approximation, we observed very pronounced conductance quantization, the structure of which depends on geometrical design and shows a spacing of $4e^2/h$, indicating the existence of valley degree of freedom. Moreover, by incorporating the third nearest approximation, we observed seminal plateaus deviated from multiples of $4e^2/h$ conductance, suggesting the lift of valley degeneracy. Finally, Quasi-one dimensional band structure calculations have been performed to study the availability of energy channels and the role of the major geometrical parameters on the transport.

description: A standard parametric maximum-likelihood technique is used to determine both the probability distribution over total HI mass $M_{\rm HI}$ and the regression of this quantity on the linear optical diameter $D_{\rm o}$ for field giant spirals (Sa-Sc) from a complete HI-flux-limited data set of these objects. Gaussian and Schechter parametrizations of the HI mass function are explored. We find that the available data are equally well described by both models, and that the different morphological classes of giant spirals have HI mass functions which, in general, agree well within the errors. The largest discrepancy corresponds to the Sb-type systems which exhibit a deficit of low HI-mass objects relative to the other types. Using a straightforward generalization of the gaussian model, we have also investigated the linear dependence of $M_{\rm HI}$ on $D_{\rm o}$. We confirm that the HI content of spirals is much better predicted by the size of their optical disks than by their morphological types alone. The inferred correlations imply a considerable decrease of the ratio $M_{\rm HI}/D_{\rm o}^2$ with increasing galaxy size for types earlier than Sc.

description: We use early-time observations of He I 10830 Åto measure the extent of upward mixing of radioactive material in SN 1987A. This work develops and extends the work of Graham (1988), and places constraints on actual explosion models. The presence of the He I 10830 Å(2s^{3}S--2p^{3}P) line at $\geq 10$ days post-explosion implies re-ionisation by $γ$-rays from upwardly-mixed radioactive material produced during the explosion. Using the unmixed explosion model 10H (Woosley 1988) as well as mixed versions of it, we estimated the $γ$-ray energy deposition by applying a purely absorptive radiative transfer calculation. The deposition energy was used to find the ionisation balance as a function of radius, and hence the 2s$^{3}$S population density profile. This was then applied to a spectral synthesis model and the synthetic spectra were compared with the observations. Neither model 10H nor the mixed version, 10HMM, succeeded in reproducing the observed He I 10830 Åline. The discrepancy with the data found for 10HMM is particularly significant, as this model has successfully reproduced the X-ray and $γ$-ray observations and the UVOIR light curve. We find that a match to the He I line profile is achieved by reducing the extent of mixing in 10HMM. Our reduced-mixing models also reproduce the observed $γ$-ray line light curves and the iron-group velocities deduced from late-time infrared line profiles. We suggest that the He I line method provides a more sensitive measure of the extent of mixing in a type II supernova explosion.

Rotating Winds from Accretion Disks in Cataclysmic Variables: Eclipse Modeling of V347 Puppis

description: We study the eclipsing nova-like variable V347 Pup by matching its UV emission line profiles in and out of eclipse to synthetic lines using a 3D kinematic and radiation transfer model. Our results support the accretion disk origin of winds in non-magnetic CVs as opposite to the WD origin. Our main point concerns the importance of rotation for the UV emission line shapes in such systems. In particular, we show that the narrowing of the UV emission lines in V347 Pup during eclipse can be easily explained by the eclipse of the innermost part of the wind by the secondary and the resulting reduction in the contribution of rotational broadening to the width of the lines. During the eclipse, the residual line flux is very sensitive to the maximal temperature of disk radiation. Good fits for reasonable mass-loss rates have been obtained for maximum disk temperatures of 50,000 degrees. This constraint was imposed either by leveling off the inner disk temperature profiles, in agreement with recent observations of some nova-like objects, or by assuming that the accretion disk does not extend to the surface of the white dwarf, in which case V347 up would be an intermediate polar. In anticipation of high-speed spectrophotometry of CVs by the HST, we provide numerical model of a time-resolved eclipse of V347 Pup or similar such system to be verified by future observations.

description: We show how the spin-transfer torque generated by an ac voltage may be used to excite a paramagnetic resonance of an atomic spin deposited on a metallic surface. This mechanism is independent of the environment of the atom and may explain the ubiquity of the paramagnetic resonance reported by Baumann $\textit{et al.}$ [$\href{http://dx.doi.org/10.1126/science.aac8703}{Science \textbf{350}, 417 (2015)}$]. The current and spin dynamics are modeled by a time-dependent Redfield master equation generalized to account for the periodic driven voltage. Our approach shows that the resonance effect is a consequence of the nonlinearity of the coupling between the magnetic moment and the spin-polarized current which generates a large second-harmonic amplitude that can be measured in the current signal.

 Arctosa littoralis: Chamberlin 1924: 673 (some specimens from Gulf of California misidentified, according to Roth & Brown 1976).
 Remarks. Arctosa serii is sympatric with A. littoralis, but the latter prefers mostly sandy beach environments (Esquivel-Bobadilla et al. 2013). Chamberlin (1924) confused some specimens of A. serii with A. littoralis because both came from similar localities. However, the larger size of A. serii (about one third larger than A. littoralis) and the paler body pattern also served to differentiate it.
 Emended diagnosis. Because of its sympatry with A. littorais, males of A. serii are recognized among all neotropical species by the shorter and sharp posterior arm of median apophysis, which is also not spatulated as in A. littoralis (Roth & Brown 1976: fig. 2). Females of A. serii are distinguished from all neotropical species by the shortest median septum in the epigyne and the narrow transversal septum (Roth & Brown 1976: figs 4, 5).

description: We present the results of a velocity correlation study of the high latitude cloud MBM16 using a fully sampled $^{12}$CO map, supplemented by new $^{13}$CO data. We find a correlation length of 0.4 pc. This is similar in size to the formaldehyde clumps described in our previous study. We associate this correlated motion with coherent structures within the turbulent flow. Such structures are generated by free shear flows. Their presence in this non-star forming cloud indicates that kinetic energy is being supplied to the internal turbulence by an external shear flow. Such large scale driving over long times is a possible solution to the dissipation problem for molecular cloud turbulence.

description: At intensities below-the-recollision threshold, we show that re-collision-induced excitation with one electron escaping fast after re-collision and the other electron escaping with a time delay via a Coulomb slingshot motion is one of the most important mechanisms of non-sequential double ionization, for strongly-driven He at 400 nm. Slingshot-NSDI is a general mechanism present for a wide range of low intensities and pulse durations. Anti-correlated two-electron escape is its striking hallmark. This mechanism offers an alternative explanation of anti-correlated two-electron escape obtained in previous studies.

description: We present an observational and theoretical study of the ionization fraction in several massive cores located in regions that are currently forming stellar clusters. Maps of the emission from the J = 1-> O transitions of C18O, DCO+, N2H+, and H13CO+, as well as the J = 2 -> 1 and J = 3 -> 2 transitions of CS, were obtained for each core. Core densities are determined via a large velocity gradient analysis with values typically 10^5 cm^-3. With the use of observations to constrain variables in the chemical calculations we derive electron fractions for our overall sample of 5 cores directly associated with star formation and 2 apparently starless cores. The electron abundances are found to lie within a small range, -6.9 < log10(x_e) < -7.3, and are consistent with previous work. We find no difference in the amount of ionization fraction between cores with and without associated star formation activity, nor is any difference found in electron abundances between the edge and center of the emission region. Thus our models are in agreement with the standard picture of cosmic rays as the primary source of ionization for molecular ions. With the addition of previously determined electron abundances for low mass cores, and even more massive cores associated with O and B clusters, we systematically examine the ionization fraction as a function of star formation activity. This analysis demonstrates that the most massive sources stand out as having the lowest electron abundances (x_e < 10^-8).

Existing work neglects user comments of fashion items, which have been proved to be effective in generating explanations along with better recommendation results. We propose a novel neural network framework, neural outfit recommendation (NOR), that simultaneously provides outfit recommendations and generates abstractive comments. NOR consists of two parts: outfit matching and comment generation. For outfit matching, we propose a convolutional neural network with a mutual attention mechanism to extract visual features. The visual features are then decoded into a rating score for the matching prediction. For abstractive comment generation, we propose a gated recurrent neural network with a cross-modality attention mechanism to transform visual features into a concise sentence. The two parts are jointly trained based on a multi-task learning framework in an end-to-end back-propagation paradigm. Extensive experiments conducted on an existing dataset and a collected real-world dataset show NOR achieves significant improvements over state-of-the-art baselines for outfit recommendation. Meanwhile, our generated comments achieve impressive ROUGE and BLEU scores in comparison to human-written comments. The generated comments can be regarded as explanations for the recommendation results. We release the dataset and code to facilitate future research.

description: Planning a safe and feasible trajectory for autonomous vehicles in real-time by fully utilizing perceptual information in complex urban environments is challenging. In this paper, we propose a spatio-temporal trajectory planning method based on graph optimization. It efficiently extracts the multi-modal information of the perception module by constructing a semantic spatio-temporal map through separation processing of static and dynamic obstacles, and then quickly generates feasible trajectories via sparse graph optimization based on a semantic spatio-temporal hypergraph. Extensive experiments have proven that the proposed method can effectively handle complex urban public road scenarios and perform in real time. We will also release our codes to accommodate benchmarking for the research community

description: We quantify the effects of Galactic extinction on the derived luminosity and diameter functions and on the density field of a redshift sample. Galaxy magnitudes are more affected by extinction than are diameters, although the effect on the latter is more variable from galaxy to galaxy, making it more difficult to quantify. We develop a maximum-likelihood approach to correct the luminosity function, the diameter function and the density field for extinction effects. The effects of random and systematic photometric errors are also investigated. The derived density field is robust to both random and systematic magnitude errors as long as these are uncorrelated with position on the sky, since biases in the derived selection function and number counts tend to cancel one another. Extinction-corrected luminosity and diameter functions are derived for several subsamples of the {\it Optical Redshift Survey} (ORS). Extinction corrections for the diameter-limited subsamples are found to be unreliable, possibly due to the superposition of random and systematic errors. The ORS subsamples are combined using overall density scaling factors from a full-sky redshift survey of \iras\ galaxies, allowing the reconstruction of the optical galaxy density field over most of the sky to 8000 \kms.

description: Model update lies at the heart of object tracking. Generally, model update is formulated as an online learning problem where a target model is learned over the online training set. Our key innovation is to \emph{formulate the model update problem in the meta-learning framework and learn the online learning algorithm itself using large numbers of offline videos}, i.e., \emph{learning to update}. The learned updater takes as input the online training set and outputs an updated target model. As a first attempt, we design the learned updater based on recurrent neural networks (RNNs) and demonstrate its application in a template-based tracker and a correlation filter-based tracker. Our learned updater consistently improves the base trackers and runs faster than realtime on GPU while requiring small memory footprint during testing. Experiments on standard benchmarks demonstrate that our learned updater outperforms commonly used update baselines including the efficient exponential moving average (EMA)-based update and the well-designed stochastic gradient descent (SGD)-based update. Equipped with our learned updater, the template-based tracker achieves state-of-the-art performance among realtime trackers on GPU.

description: The 24-Hour Activity Cycle integrates the activity behaviours of physical activity, sedentary behaviour and sleep; each of which are associated with health and wellbeing outcomes in adolescents. The aim of this thesis was to examine the 24-Hour Activity Cycle in a sample of Irish adolescents tracked across three time points and investigate potential differences by gender and day type.Repeated measures data was collected in two schools in Ireland as part of the Active School Flag Post-Primary Feasibility Study in autumn 2018, spring 2019 and autumn 2019. Activity behaviour data were derived from activPAL3 micro data. Separate repeated measures tests examined differences in the activity cycles across time points (i) across the whole week, (ii) across the whole week stratified by gender, (iii) on weekdays and weekend days, (iv) on weekdays and weekend days stratified by gender. Estimated Marginal Means and Post Hoc Pairwise Comparisons with Bonferroni adjustment were used to estimate and examine mean differences, the magnitude of effects were quantified using Cohen’s D and Hedges D.Fifty four adolescents (mean age = 14.22 ± 1.59, 67% female) were included in the final analyses. The average 24-Hour Activity Cycle observed included: 39.13% sleep; 41.14% SB; 12.04% standing; 4.26% light-intensity physical activity; 3.24% moderate-to-vigorous physical activity. Less sleep (~20 minutes) was observed in spring compared to autumn time points; less moderate-to-vigorous (~15 minutes) and light intensity (~15 minutes) physical activity was observed in females than males; less sleep (~71 minutes), more sedentary behaviour (~75 minutes), less light-intensity physical activity (~12 minutes) and more moderate-to-vigorous physical activity (~13 minutes) was observed on weekdays than weekend days.This research highlights the prevalence of sub-optimal activity behaviours in the sample. Health promotion efforts are required to enhance adolescent activity behaviour to enrich health and well-being, while seasonal, gender and day type specific interventions should be tailored for the greatest impact.

description: Magnetodielectric (MD) materials are important for their ability to spin-charge conversion, magnetic field control of electric polarization and vice versa. Among these, two-dimensional (2D) van der Waals (vdW) magnetic materials are of particular interest due to the presence of magnetic anisotropy (MA) originating from the interaction between the magnetic moments and the crystal field. Also, these materials indicate a high degree of stability in the long-range spin order and may be described using suitable spin Hamiltonians of the Heisenberg, XY, or Ising type. Recent reports have suggested effective interactions between magnetization and electric polarization in 2D magnets. However, MD coupling studies on layered magnetic materials are still few. This review covers the fundamentals of magnetodielectric coupling by explaining related key terms. It includes the necessary conditions for having this coupling and sheds light on the possible physical mechanisms behind this coupling starting from phenomenological descriptions. Apart from that, this review classifies 2D magnetic materials into several categories for reaching out each and every class of materials. Additionally, this review summarizes recent advancements of some pioneer 2D magnetodielectric materials. Last but not the least, the current review provides possible research directions for enhancing magnetodielectric coupling in those and mentions the possibilities for future developments.

Metal complexes as catalysts for the synthesis of heterocycles
Creators: name: Lal, Steven
Publisher: name: Imperial College London
Year: 2013

description: Transition metal-based catalysts are undoubtedly one of the most powerful tools available to chemists. They mediate a plethora of reactions, and make numerous chemical processes viable while allowing cleaner/greener and safer routes. Most transformations require the use of ancillary ligands, and in practice, the actual catalytically active species might be formed either by the in situ combination of metal and ligand precursors, or directly from a pre- formed, well-defined organometallic complex. Pre-formed catalysts possess many advantages over in situ -generated systems. Not only are they usually better performing, but also allow strict control over the ligand/metal ratio. This is of importance since an increasing number of ligands are more expensive than common metal sources. More significantly, such control should be helpful to identify the actual catalyst, and hence, to better understand the reaction mechanism. This thesis describes the efforts in developing well-defined catalytic systems for the preparation and functionalisation of heterocycles, with a particular focus on 1,2,3- triazoles. The introductory Chapter outlines a brief overview of the chemistry of azides, including a discussion of the ligands and catalysts used for the 1,3-dipolar cycloaddition reaction of or ganic azides and alkynes. The synthesis, characterisation and X-ray crystal structures of novel copper(I) catalysts bearing phosphorus-based ligands is described in Chapter 2. These pre-formed catalysts have been screened in the copper(I)-catalysed azide-alkyne cycloaddition reaction. The scope and trends in reactivity are also described. The following Chapter provides an introduction to the ruthenium-catalysed azide-alkyne cycloaddition reaction and the efforts in developing water-soluble catalysts and substrates and testing them in this cycloaddition reaction. In Chapter 4, results of attempted metal-catalysed cycloadditions of azides and internal alkynes are presented. In addition, the development of two new catalytic systems for the preparation of 5-iodo-1,2,3-triazoles using pre-formed catalysts is discussed. Mechanistic studies for this transformation are also included. Chapter 5 includes our attempted functionalisation reactions of 5-iodo-1,2,3-triazoles. Furthermore, copper-catalysed direct arylation reactions of 1,2,3-triazoles are reviewed, and the results of the copper-catalysed direct arylation of 1,4-disubstituted-1,2,3-triazoles are included. The final Chapter contains experimental procedures and characterisation data of all compounds synthesised during this project.
