description: The surface functionalization of diamond has been extensively studied through a variety of techniques, such as oxidation. Several oxygen groups have been correspondingly detected on the oxidized diamond, such as COC (ester), CO (ketonic), and COH (hydroxyl). However, the composition and relative concentration of these groups on diamond surfaces can be affected by the type of oxygenation treatment and the diamond surface quality. To investigate the stability of the oxygenated groups at specific diamond surfaces, we evaluated through fully atomistic reactive molecular mechanics (FARMM) simulations, using the ReaxFF force field, the formation energies of CO, COC, and COH groups on pristine and defective diamond surfaces (110), (111), and (311). According to our findings, the COH group has the lowest formation energy on a perfect (110) surface, while the COC is favored on a defective surface. As for the (111) surface, the COC group is the most stable for both pristine and defective surfaces. Similarly, COC group is also the most stable one on the defective/perfect (311) surface. In this way, our results suggest that if in a diamond film the (110) surface is the major exposed facet, the most adsorbed oxygen group could be either COH or COC, in which the COC would depend on the level of surface defects.

description: We present deep, near-infrared images of the circumbinary disk surrounding the pre-main-sequence binary star, GG Tau A, obtained with NICMOS aboard the Hubble Space Telescope. The spatially resolved proto-planetary disk scatters roughly 1.5% of the stellar flux, with a near-to-far side flux ratio of ~1.4, independent of wavelength, and colors that are comparable to the central source; all of these properties are significantly different from the earlier ground-based observations. New Monte Carlo scattering simulations of the disk emphasize that the general properties of the disk, such as disk flux, near side to far side flux ratio and integrated colors, can be approximately reproduced using ISM-like dust grains, without the presence of either circumstellar disks or large dust grains, as had previously been suggested. A single parameter phase function is fitted to the observed azimuthal variation in disk flux, providing a lower limit on the median grain size of 0.23 micron. Our analysis, in comparison to previous simulations, shows that the major limitation to the study of grain growth in T Tauri disk systems through scattered light lies in the uncertain ISM dust grain properties. Finally, we use the 9 year baseline of astrometric measurements of the binary to solve the complete orbit, assuming that the binary is coplanar with the circumbinary ring. We find that the estimated 1 sigma range on disk inner edge to semi-major axis ratio, 3.2 < Rin/a < 6.7, is larger than that estimated by previous SPH simulations of binary-disk interactions.

description: Morphological attributes from histopathological images and molecular profiles from genomic data are important information to drive diagnosis, prognosis, and therapy of cancers. By integrating these heterogeneous but complementary data, many multi-modal methods are proposed to study the complex mechanisms of cancers, and most of them achieve comparable or better results from previous single-modal methods. However, these multi-modal methods are restricted to a single task (e.g., survival analysis or grade classification), and thus neglect the correlation between different tasks. In this study, we present a multi-modal fusion framework based on multi-task correlation learning (MultiCoFusion) for survival analysis and cancer grade classification, which combines the power of multiple modalities and multiple tasks. Specifically, a pre-trained ResNet-152 and a sparse graph convolutional network (SGCN) are used to learn the representations of histopathological images and mRNA expression data respectively. Then these representations are fused by a fully connected neural network (FCNN), which is also a multi-task shared network. Finally, the results of survival analysis and cancer grade classification output simultaneously. The framework is trained by an alternate scheme. We systematically evaluate our framework using glioma datasets from The Cancer Genome Atlas (TCGA). Results demonstrate that MultiCoFusion learns better representations than traditional feature extraction methods. With the help of multi-task alternating learning, even simple multi-modal concatenation can achieve better performance than other deep learning and traditional methods. Multi-task learning can improve the performance of multiple tasks not just one of them, and it is effective in both single-modal and multi-modal data.

description: We show that if the primordial classical perturbations were generated by the gravitational particle creation during inflation, and followed by an evolution of quantum-to-classical transition,the time dependent correlation of these perturbations is long-tailed with a correlation time larger than the Hubble-time. Consequently, the inflationary perturbations are locally scale-scale correlated. Hence, the interaction of the fields during inflation can be explored via the detection of the local scale-scale correlation of the CMB fluctuations.

description: Recently, a novel method for developing filtering algorithms, based on the interconnection of two Bayesian filters and called double Bayesian filtering, has been proposed. In this manuscript we show that the same conceptual approach can be exploited to devise a new smoothing method, called double Bayesian smoothing. A double Bayesian smoother combines a double Bayesian filter, employed in its forward pass, with the interconnection of two backward information filters used in its backward pass. As a specific application of our general method, a detailed derivation of double Bayesian smoothing algorithms for conditionally linear Gaussian systems is illustrated. Numerical results for two specific dynamic systems evidence that these algorithms can achieve a better complexity-accuracy tradeoff and tracking capability than other smoothing techniques recently appeared in the literature.

description: We report VLA radio observations of 29 SNe with ages ranging from 10 days to about 90 years past explosion. These observations significantly contribute to the existing data pool on such objects. Included are detections of known radio SNe~1950B, 1957D, 1970G, 1983N, the suspected radio SN 1923A, and the possible radio SN 1961V. None of the remaining 23 observations resulted in detections, providing further evidence to support the observed trend that most SNe are not detectable radio emitters. To investigate the apparent lack of radio emission from the SNe reported here, we have followed standard practice and used Chevalier's ``standard model'' to derive (upper limits to) the mass-loss rates for the super nova progenitors. These upper limits to the fluxes are consistent with a lack of circumstellar material needed to provide detectable radio emission for SNe at these ages and distances. Comparison of the radio luminosities of these supernovae as a function of age past explosion to other well-observed radio SNe indicates that the Type II SNe upper limits are more consistent with the extrapolated light curves of SN 1980K than of SN 1979C, suggesting that SN 1980K may be a more typical radio emitter than SN 1979C. For completeness, we have included an appendix where the results of analyses of the non-SN radio sources are presented. Where possible, we make (tentative) identifications of these sources using various methods.

description: Organometallic complexes have proven to have significant nonlinear optical (NLO) properties. They possess great design flexibility; the metal, oxidation state, ligand environment and geometry can all be varied, they may be strong oxidizing or reducing agents, and they are often able to undergo facile NLO switching. Metal alkynyl complexes form an important group of organometallic complexes that have high potential in NLO material applications. The focus of the current study is to establish structure-property relationship for ruthenium alkynyl complexes incorporating chiral R,R-Chiraphos co-ligands, and to compare the behavior of these complexes to those of analogous complexes containing the archetypical co-ligand 1,2-bis(diphenylphosphino)ethane (dppe), one of the most widely-employed diphosphine ligands in this field. Chapter 1 presents an introduction to nonlinear optics and reviews organic, inorganic and organometallic compounds for which nonlinear optical responses have been measured. Chapter 2 covers the synthesis of linear ruthenium alkynyl complexes incorporating R,R-Chiraphos. Their crystal structures, electrochemical and spectroelectrochemical properties, circular dichroism responses, and linear and quadratic nonlinear optical properties are reported. Chapter 3 reports the synthesis of ruthenium alkynyl dendrimers incorporating R,R-Chiraphos. The crystal structures, electrochemical properties, linear optical properties and circular dichroism responses of selected examples have been carried out.

Modified Braid Equations for SO_q (3) and noncommutative spaces

description: General solutions of the $\hat{R}TT$ equation with a maximal number of free parameters in the specrtal decomposition of vector $SO_q (3)$ $\hat{R}$ matrices are implemented to construct modified braid equations (MBE). These matrices conserve the given, standard, group relations of the nine elements of T, but are not constrained to satisfy the standard braid equation (BE). Apart from q and a normalisation factor our $\hat{R}$ contains two free parameters, instead of only one such parameter for deformed unitary algebras studied in a previous paper [1] where the nonzero right hand side of the $MBE$ had a linear term proprotional to $(\hat{R}_{(12)} - \hat{R}_{(23)})$. In the present case the r.h.s. is, in general, nonliear. Several particular solutions are given (Sec.2) and the general structure is analysed (App.A). Our formulation of the problem in terms of projectors yield also two new solutions of standard (nonmodified) braid equation (Sec.2) which are further discussed (App.B). The noncommutative 3-spaces obtained by implementing such generalized $\hat{R}$ matrices are studied (Sec.3). The role of coboundary $\hat{R}$ matrices (not satisfying the standard BE) is explored. The MBE and Baxterization are presented as complementary facets of the same basic construction, namely, the general solution of $\hat{R}TT$ equation (Sec.4). A new solution is presented in this context. As a simple but remarkable particular case a nontrivial solution of BE is obtained (App.B) for q=1. This solution has no free parameter and is not obtainable by twisting the identity matrix. In the concluding remarks (Sec.5), among other points, generalisation of our results to $SO_{q}(N)$ is discussed.

description: Several different evolutionary processes allow enzymes to gain new catalytic activity, or enhance existing properties. Xenobiotic-degrading enzymes are often used to study the molecular basis for the evolution of new catalytic activity, as the substrates are often synthetic and comparatively new to the biosphere, the directionality of the evolutionary process is generally known and the evolved protein can often be traced back to a specific ancestral enzyme. However, the molecular basis behind the evolution of novel catalytic activities in different xenobiotic degrading enzymes is not well understood. In this work several different xenobiotic hydrolysing metalloenzymes were investigated to better understand new enzymatic reactions can evolve: the bacterial phosphotriesterases, triazine chlorohydrolases, and linuron/molinate hydrolases. These three enzyme families were studied using a combination of protein crystallography, enzyme kinetics, metal-ion dependence analysis, thermostability and solubility quantification, bioinformatics analyses, and critical analysis relevant literature. The conclusions that were drawn from these investigations cover fundamental concepts relating to enzymatic catalysis, including (1) the role of metal-ion cofactors in catalysis and the evolution of new function, (2) the desolvation of charged catalytic residues, the energetic cost of this desolvation and how this contributes to catalysis, and (3) the epistatic restrictions imposed on the evolution of new enzyme activity. Various smaller milestones were accomplished as a result of these investigations. The molecular structures of hydrolases for the herbicides molinate and linuron (molinate hydrolase and phenylurea hydrolase B) have been solved for the first time and, in combination with extensive kinetic and metal analysis, a catalytic mechanism has been proposed. This information will be useful for optimization of both enzymes for the bioremediation of herbicide-contaminated sites. Detailed information outlining the structural and catalytic basis of triazine hydrolase activity and solubility was also obtained. Work towards understanding the structural basis underlying how triazine hydrolase can accumulate in a soluble, active, form and catalyse the hydrolysis of triazine based herbicides will aid the future protein engineering of more stable or active variants. The activity of phosphotriesterase was improved 5000-fold with the most widely used pesticide in the US, malathion. This phosphotriesterase variant has great potential for bioremediation applications and also provides a useful case study into the role that epistasis plays in the engineering of improved enzyme function. Finally, future research ideas are proposed, using results described in this work.

description: The understanding of the asymptotic decay of correlations and of the distribution of Poincaré recurrence times $P(t)$ has been a major challenge in the field of Hamiltonian chaos for more than two decades. In a recent Letter, Chirikov and Shepelyansky claimed the universal decay $P(t) \sim t^{-3}$ for Hamiltonian systems. Their reasoning is based on renormalization arguments and numerical findings for the sticking of chaotic trajectories near a critical golden torus in the standard map. We performed extensive numerics and find clear deviations from the predicted asymptotic exponent of the decay of $P(t)$. We thereby demonstrate that even in the supposedly simple case, when a critical golden torus is present, the fundamental question of asymptotic statistics in Hamiltonian systems remains unsolved.

description: The non-linear behaviour of Randall-Sundrum gravity with one brane is examined. Due to the non-compact extra dimension, the perturbation spectrum has no mass gap, and the long wavelength effective theory is only understood perturbatively. The full 5-dimensional Einstein equations are solved numerically for static, spherically symmetric matter localized on the brane, yielding regular geometries in the bulk with axial symmetry. An elliptic relaxation method is used, allowing both the brane and asymptotic radiation boundary conditions to be simultaneously imposed. The same data that specifies stars in 4-dimensional gravity, uniquely constructs a 5-dimensional solution. The algorithm performs best for small stars (radius less than the AdS length) yielding highly non-linear solutions. An upper mass limit is observed for these small stars, and the geometry shows no global pathologies. The geometric perturbation is shown to remain localized near the brane at high densities, the confinement interestingly increasing for both small and large stars as the upper mass limit is approached. Furthermore, the static spatial sections are found to be approximately conformal to those of AdS. We show that the intrinsic geometry of large stars, with radius several times the AdS length, is described by 4-dimensional General Relativity far past the perturbative regime. This indicates that the non-linear long wavelength effective action remains local, even though the perturbation spectrum has no mass gap. The implication is that Randall-Sundrum gravity, with localized brane matter, reproduces relativistic astrophysical solutions, such as neutron stars and massive black holes, consistent with observation.

description: The field of two-dimensional (2D) materials has expanded to multilayered systems where electronic, optical, and mechanical properties change-often dramatically-with stacking order, thickness, twist, and interlayer spacing [1-5]. For transition metal dichalcogenides (TMDs), bond coordination within a single van der Waals layer changes the out-of-plane symmetry that can cause metal-insulator transitions [1, 6] or emergent quantum behavior [7]. Discerning these structural order parameters is often difficult using real-space measurements, however, we show 2D materials have distinct, conspicuous three-dimensional (3D) structure in reciprocal space described by near infinite oscillating Bragg rods. Combining electron diffraction and specimen tilt we probe Bragg rods in all three dimensions to identify multilayer structure with sub-Angstrom precision across several 2D materials-including TMDs (MoS2, TaSe2, TaS2) and multilayer graphene. We demonstrate quantitative determination of key structural parameters such as surface roughness, inter- & intra-layer spacings, stacking order, and interlayer twist using a rudimentary transmission electron microscope (TEM). We accurately characterize the full interlayer stacking order of multilayer graphene (1-, 2-, 6-, 12-layers) as well the intralayer structure of MoS2 and extract a chalcogen-chalcogen layer spacing of 3.07 +/- 0.11 Angstrom. Furthermore, we demonstrate quick identification of multilayer rhombohedral graphene.

description: We report the initial results of a deep imaging survey of galaxy clusters. The primary goals of this survey are to quantify the amount of intracluster light as a function of cluster properties, and to quantify the frequency of tidal debris. We outline the techniques needed to perform such a survey, and we report findings for the first two galaxy clusters in the survey: Abell 1413, and MKW 7 . These clusters vary greatly in richness and structure. We show that our surface photometry reliably reaches to a surface brightness of μ_v = 26.5 mags per arcsec. We find that both clusters show clear excesses over a best-fitting r^{1/4} profile: this was expected for Abell 1413, but not for MKW 7. Both clusters also show evidence of tidal debris in the form of plumes and arc-like structures, but no long tidal arcs were detected. We also find that the central cD galaxy in Abell 1413 is flattened at large radii, with an ellipticity of $\approx 0.8$, the largest measured ellipticity of any cD galaxy to date.

Transient bioheat transfer analysis in biological tissues by fundamental-solution-based numerical methods

description: Taylor's expansion approach was applied to linearize the nonlinear term in the original nonlinear bioheat transfer governing equation. Then the DRM and the MFS was established to obtain the particular and homogeneous solutions. The influence of blood perfusion rate on temperature distribution in the skin tissue was analysed by changing the coefficients in the three expressions of blood perfusion rate. Numerical results showed that the variation of blood perfusion rate plays a significant role in the temperature distribution within the skin tissue. Finally, a meshless numerical scheme combining the operator splitting method (OSM), the RBF interpolation and the MFS was developed for solving transient nonlinear bioheat problems in two-dimensional skin tissue. In the numerical scheme, the nonlinearity caused by the temperature-dependent blood perfusion rate (TDBPR) is taken into consideration. In the procedure, the OSM is used to separate the Laplacian operator and the nonlinear source term, and then second-order time-stepping schemes are employed for approximating two splitting operators in order to convert the original governing equation into a linear nonhomogeneous Helmholtz-type governing equation (NHGE) at each time step. The full fields consisting of the particular and homogeneous solutions are enforced to fit the NHGE at interpolation points and the boundary conditions at boundary collocations to determine unknowns at each time step. The proposed method was verified by comparison with other methods. Furthermore, the sensitivity of the coefficients in cases of a linear and an exponential relationship of TDBPR was investigated to reveal their bioheat effect on the skin tissue.

description: Community Supported Agriculture (CSA) is a system whereby members purchase shares in a farm in the spring and then receive produce (maple syrup, meat, honey, vegetables, fruit, etc.) over the course of the growing season. The significance of this system is contested with critics, chiefly sociologist Julie Guthman (2008), asserting that CSA reproduces neoliberalism. Guthman's thesis on the relationship between practices, subjectivities, and political imaginaries is generative. My intervention is predominantly methodological. Guthman offers a systemic overview, in keeping with Michel Foucault's scholarship on governmentality, but does not explore the embodied nature of governmentality at the scale of the people involved. I contend that to understand how neoliberal governmentality plays out in CSA, we need to explore embodied practices at the scale of the people involved. I rely on Dorothy Smith's agent perspective and examine the practices associated with CSA for a discursive reading of those practices. My discursive reading employs J.K. Gibson-Graham's diverse economies approach. Participation in CSA cultivates a sense of connection to a local geographic community, and a community of practice, contrary to the seemingly individualized nature of the market transactions which form the basis of CSA. This sense of connection is supportive of prefigurative practices, farming practices, and activism. The relationality experienced by CSA farmers and members undergirds political activism, and the connection to communities of practice galvanizes and supports both discursive and protest practices. Attention to discourse at the scale of the individual provides insight into how discourses are co-produced and allows us to observe discourses in various stages of development, from those just entering the public square on social media, to those further developed, conceptually rich, with saliency for both farmers and members, and linked to political protest. The communities that exist in opposition to the individualization of neoliberalism, the production of discourse that both resists and reinscribes neoliberalism, and the practices that shape our subjects and political imaginaries, visible at this scale, provide insight into the connection between local and global discourses, and the connection between everyday practices and protest.

N o t e s: This species was described (BORDONI 2002) from Doi Suthep, near Chiang Mai, in North Thailand, on the basis of a female preserved in the Naturhistorisches Museum of Berlin. So far the male was unknown, therefore I figure the labrum (fig. 1), usually an important systematic character, and I propose a short description of the male genital characters: tergite of the genital segment very narrow and extended (fig. 2), sternite as in fig. 3; aedeagus of big size (2 mm long), extended, with sinuate lateral sides, asymmetrical parameres and internal sac rolled ribbon-like, covered by very small and sparce scales (fig. 4). This is the smallest species of the genus known so far (body 15-19 mm long).

Complete and consistent atomic data, including excitation energies, lifetimes, wavelengths, and E1, E2, M1 line strengths, oscillator strengths, and transition rates among these 318 levels are provided. Comparisons are made between the present two data sets, as well as with other available experimental and theoretical values. The present data are accurate enough for identification and deblending of emission lines involving the $n=3,4$ levels and are also useful for modeling and diagnosing fusion plasmas\kw{. These data can} be considered as a benchmark for other calculations.
