description: Machine learning models have emerged as powerful tools in physics and engineering. Although flexible, a fundamental challenge remains on how to connect new machine learning models with known physics. In this work, we present an autoencoder with latent space penalization, which discovers finite dimensional manifolds underlying the partial differential equations of physics. We test this method on the Kuramoto-Sivashinsky (K-S), Korteweg-de Vries (KdV), and damped KdV equations. We show that the resulting optimal latent space of the K-S equation is consistent with the dimension of the inertial manifold. The results for the KdV equation imply that there is no reduced latent space, which is consistent with the truly infinite dimensional dynamics of the KdV equation. In the case of the damped KdV equation, we find that the number of active dimensions decreases with increasing damping coefficient. We then uncover a nonlinear basis representing the manifold of the latent space for the K-S equation.

description: It is demonstrated that an understanding of the 5/2 fractional quantum Hall effect can be achieved within the composite fermion theory without appealing to the Pfaffian wave function. The residual interaction between composite fermions plays a crucial role in establishing incompressibility at this filling factor. This approach has the advantage of being amenable to systematic perturbative improvements, and produces ground as well as excited states. It, however, does not relate to non-Abelian statistics in any obvious manner.

description: Molecular dynamics (MD) simulations are a widely-accepted method for studying biomolecular systems. They are particularly useful for investigating stable protein structures where the range of configurations to be sampled is relatively small. Proteins and peptides with regions that lack regular structure pose a much more challenging sampling problem for MD simulations. An understanding of the structure and behaviour of such disordered regions is essential, because such regions are found in a significant number of proteins. Further, the lack of structure normally confers functional advantages, such as the capacity to bind several different other molecules. The need for reliable MD simulation methods is more important in such disordered cases, as experimental techniques are often inadequate. This thesis investigates the theory and practice of MD simulations, with a view to enhancing their capacity to simulate such systems efficiently on high-performance computers. In particular, the thesis examines in detail the replica-exchange molecular dynamics (REMD) method, which has become a popular tool for increasing sampling of challenging free-energy landscapes. It presents guidelines for best practice in running REMD simulations, and demonstrates a flaw in the theory that determines how replica exchanges occur. This flaw is shown to be significant in practice, and a solution is proposed and tested. The particle-mesh Ewald (PME) algorithm is widely used to treat the important electrostatic component of MD simulation models. This thesis shows how best to choose the parameters of the PME method in the MD simulation software GROMACS so that the full periodic Coulomb interaction is approximated at a known level of accuracy and minimal computational cost on various hardware. It is hoped that this will stimulate future work on the level of accuracy required for effective sampling. Also in this work, the performance of the inner loops of GROMACS on the BlueGene/L and BlueGene/P supercomputer families was improved by around 11%. Most of the aforementioned work has already appeared in peer-reviewed literature. Finally, these techniques were applied to large-scale microsecond-length REMD simulations of a disordered peptide. The peptide of interest was the tandem octapeptide repeat region of the N-terminal disordered region of human prion protein. Three of the tandem repeats were simulated. The results were compared with existing experimental studies of this peptide system. Some evidence of ordered structure was identified; in particular, interactions at close distance between side chains of all pairs of aromatic residues were observed.

description: El propósito de este artículo es mostrar el recorrido realizado en la construcción de espacios y sentidos sobre la formación docente para la educación de las infancias en una provincia del norte argentino. Desde 1960, se evidencia un trabajo sistemático en pos de jerarquizar la formación docente específica, que llega a un punto cúlmine con la elaboración del primer plan de estudios del Profesorado en Educación Pre-Elemental en el ámbito de una universidad pública. Este artículo es el resultado de un trabajo de investigación acreditado que adoptó un abordaje histórico, particularmente desde el campo de la historia de la educación. Desde allí, se realizó un trabajo de archivo que permitió el conocimiento de una matriz de sentidos sobre la formación docente para educar a las infancias, construida en las décadas de 1960 y 1970 en el interjuego de perspectivas epistemológicas sobre las infancias y la formación, perspectivas que se hicieron cuerpo en mujeres formadas en diferentes ámbitos. En este planteo, se identifican personas provenientes de diferentes provincias que representan perspectivas teóricas diversas, pero que abonan un camino de construcción colectiva de la formación docente. Asimismo, se reconoce el trabajo mancomunado de diferentes sectores, como el Estado provincial y la universidad. Desde este aporte, se proponen argumentos para sostener el carácter pedagógico de la educación preelemental y la relevancia de la formación docente de calidad para el trabajo educativo con las infancias.

description: We have measured the spatial and spectral dependence of the microwave field inside an open absorbing waveguide filled with randomly juxtaposed dielectric slabs in the spectral region in which the average level spacing exceeds the typical level width. Whenever lines overlap in the spectrum, the field exhibits multiple peaks within the sample. Only then is substantial energy found beyond the first half of the sample. When the spectrum throughout the sample is decomposed into a sum of Lorentzian lines plus a broad background, their central frequencies and widths are found to be essentially independent of position. Thus, this decomposition provides the electromagnetic quasimodes underlying the extended field in nominally localized samples. When the quasimodes overlap spectrally, they exhibit multiple peaks in space.

description: Two-dimensional topological insulators (2DTIs), which host the quantum spin Hall (QSH) effect, are one of the key materials in next-generation spintronic devices. To date, experimental evidence of the QSH effect has only been observed in a few materials, and thus, the search for new 2DTIs is at the forefront of physical and materials science. Here, we report experimental evidence of a 2DTI in the van der Waals material Ta$_2$Pd$_3$Te$_5$. First-principles calculations show that each monolayer of Ta$_2$Pd$_3$Te$_5$ is a 2DTI with weak interlayer interactions. Combined transport, angle-resolved photoemission spectroscopy, and scanning tunneling microscopy measurements confirm the existence of a band gap at the Fermi level and topological edge states inside the gap. These results demonstrate that Ta$_2$Pd$_3$Te$_5$ is a promising material for fabricating spintronic devices based on the QSH effect.

description: Modelling the extremal dependence structure of spatial data is considerably easier if that structure is stationary. However, for data observed over large or complicated domains, non-stationarity will often prevail. Current methods for modelling non-stationarity in extremal dependence rely on models that are either computationally difficult to fit or require prior knowledge of covariates. Sampson and Guttorp (1992) proposed a simple technique for handling non-stationarity in spatial dependence by smoothly mapping the sampling locations of the process from the original geographical space to a latent space where stationarity can be reasonably assumed. We present an extension of this method to a spatial extremes framework by considering least squares minimisation of pairwise theoretical and empirical extremal dependence measures. Along with some practical advice on applying these deformations, we provide a detailed simulation study in which we propose three spatial processes with varying degrees of non-stationarity in their extremal and central dependence structures. The methodology is applied to Australian summer temperature extremes and UK precipitation to illustrate its efficacy compared to a naive modelling approach.

Formation of Galactic Systems in Light of the Magnesium Abundance in Field Stars.III.the Halo

Publisher: name: arXiv

description: We analyze the relations between the relative magnesium abundances, metallicities, and Galactic orbital elements for halo stars. We show that the relative magnesium abundances in protodisk halo stars are virtually independent of metallicity and lie within a fairly narrow range while presumably accreted stars demonstrate a large spread in relative magnesium abundances up to negative [Mg/Fe]. The mean metallicity of magnesium-poor ([Mg/Fe]<0.2 dex) accreted stars has been found to be displaced toward the negative values when passing from stars with low azimuthal velocities to those with high ones at Δ[Fe/H]=0.5dex. The mean apogalactic radii and inclinations of the orbits also increase while their eccentricities decrease. As a result negative radial and vertical gradients in relative magnesium abundances are observed in the accreted halo in the absence of correlations between the [Mg/Fe] ratios and other orbital elements, while these correlations are found at a high significance level for genetically related Galactic stars. We surmise that as the masses of dwarf galaxies decrease, the maximum SNII masses and hence, the yield of α-elements in them also decrease. In this case, the relation between the [Mg/Fe] ratios and the inclinations and sizes of the orbits of accreted stars is in complete agreement with numerical simulations of dynamical processes during the interaction of galaxies. Thus the behavior of the magnesium abundance in accreted stars suggests that the satellite galaxies are disrupted and lose their stars en masse only after dynamical friction reduces significantly the sizes of their orbits and drags them into the Galactic plane. Less massive satellite galaxies are disrupted even before their orbits change appreciably under tidal forces.

description: In considering the impact of ideologies, is it important that both organizational and budgetary ideologies that affect educational delivery to emergent bilingual (EB) students) be understood regarding the budgetary decisions made in school districts serving high percentages of EB students. Therefore, the purpose of the study was to examine budget formation within charter schools based on a critical analysis of the ideologies from which decisions about funding affected EB students. The field study was the most appropriate design for an in-depth analysis of the perceptions about funding and EB students had by superintendents leading charter schools. The criteria for participating in an interview required superintendents to lead open-enrollment K-12 charter schools located in North Texas, which contained over 40 different charter school systems. However, charter school district superintendents had to be serving a school district with an EB student population of at least 60% of its total enrollment. Each interview lasted between 1.5 and 3 hours and revealed the three participants had extensive education experience in a public charter school, had been in their current roles for at least 10 years, and had held other positions within their charter districts prior to assuming their current superintendencies. The three superintendents represented four charter school districts, as one superintendent split time between two charter districts. Four themes emerged to represent the ideologies and budget priorities of the charter school district superintendents who discussed EB funding in three charter districts with high concentrations of EB students: (a) teacher training, certification, and shortages, (b) funding, accountability, and policies, (c) equity in mind, and (d) funding and teacher student ratios. The findings suggest this critical analysis of charter school budgeting can be used to affect the current understanding of school organizations and the ways Texas public schools and districts could inadvertently negatively influence the learning outcomes for students of color who include EB students and students of other minority groups who could benefit from bilingual education. Chapter 5 concludes the study with recommendations for policy, practice, and research.

The biomechanics of load carriage during steady-state human walking

description: Load carriage presents a significant challenge to balance control and results in increased fall risk and injury. The goal of this research was to understand the effects of load carriage on gait asymmetry, biomechanical demand and muscle contributions to support and propulsion during walking. This research evaluated gradual load changes during pregnancy, as well as sudden load changes in individuals with unilateral transtibial amputation. Over one quarter of pregnant women will experience a fall during their pregnancy. Thus, we sought to identify the relationships between pregnancy progression, multiple pregnancies and gait asymmetry (a predictor of fall risk). We found that gait asymmetry increased as pregnancy progressed, and that the magnitude of asymmetry was greater for the second pregnancy relative to the first. In addition to increased fall risk, individuals with transtibial amputation often develop conditions such as intact limb osteoarthritis and fatigue. Load carriage increases these risks as these individuals lack their residual limb ankle plantarflexor muscles, which are critical for mobility, and depend more heavily on their intact limb. Thus, modeling and simulation was used to identify the effects of five loading positions and five commercially available prostheses on muscle contributions to support and propulsion. We found that the Gluteus Maximus, Soleus, Gastrocnemius and prosthesis responded the most to load carriage; further, the intact-side muscles responded more to load carriage. Finally, we found that carrying a front load resulted in greater metabolic cost than other load carriage positions, and that stiffer prosthetic feet may not be advantageous for load carriage. A final study explored the effects of loading position and various prosthetic feet on measures of biomechanical demand, including metabolic cost, intact knee impulses and total muscle stress. We found that load carriage resulted in increased biomechanical demand relative to the unloaded condition. Carrying a front load resulted in the greatest increase in metabolic cost, while an intact-side load resulted in the greatest increase in intact knee loads and the back, intact and residual-side loads resulted in the greatest total muscle stress. The clinically prescribed foot and prescribed foot with a heel-stiffening wedge resulted in the lowest demand.

description: We attempt to clarify certain puzzles concerning state collapse and decoherence. In open quantum systems decoherence is shown to be a necessary consequence of the transfer of information to the outside; we prove an upper bound for the amount of coherence which can survive such a transfer. We claim that in large closed systems decoherence has never been observed, but we will show that it is usually harmless to assume its occurrence. An independent postulate of state collapse over and above Schroedinger's equation and the probability interpretation of quantum states, is shown to be redundant.

description: The presence or absence of intermediate-mass black holes (IMBHs) at the centre of Milky Way globular clusters (GCs) is still an open question. This is either due to observational restrictions or limitations in the dynamical modelling method; in this work, we explore the latter. Using a sample of high-end Monte Carlo simulations of GCs, with and without a central IMBH, we study the limitations of spherically symmetric Jeans models assuming constant velocity anisotropy and mass-to-light ratio. This dynamical method is one of the most widely used modelling approaches to identify a central IMBH in observations. With these models, we are able to robustly identify and recover the mass of the central IMBH in our simulation with a high-mass IMBH ($M_{\rm IMBH}/M_{\rm GC}\sim4\%$). Simultaneously, we show that it is challenging to confirm the existence of a low-mass IMBH ($M_{\rm IMBH}/M_{\rm GC}\sim0.3\%$), as both solutions with and without an IMBH are possible within our adopted error bars. For simulations without an IMBH we do not find any certain false detection of an IMBH. However, we obtain upper limits which still allow for the presence of a central IMBH. We conclude that while our modelling approach is reliable for the high-mass IMBH and does not seem to lead towards a false detection of a central IMBH, it lacks the sensitivity to robustly identify a low-mass IMBH and to definitely rule out the presence of an IMBH when it is not there.

description: We study half-BPS line defects in $\mathcal{N}=2$ superconformal theories using the bootstrap approach. We concentrate on local excitations constrained to the defect, which means the system is a $1d$ defect CFT with $\mathfrak{osp}(4^*|2)$ symmetry. In order to study correlation functions, we construct a suitable superspace and then use the Casimir approach to calculate a collection of new superconformal blocks. Special emphasis is given to the displacement operator, which controls deformations orthogonal to the defect and is always present in a defect CFT. After writing crossing symmetry we proceed with a numerical and analytical bootstrap analysis. We obtain numerical bounds on the CFT data and compare them to known solutions. We also present an analytic perturbative solution to the crossing equations, and argue that this solution most likely captures line defects in $\mathcal{N}=2$ gauge theories at strong coupling.

description: Motivated by recent results on non-vanishing spatial curvature \cite{curve} we employ the holographic model of dark energy to investigate the validity of first and second laws of thermodynamics in non-flat (closed) universe enclosed by apparent horizon $R_A$ and the event horizon measured from the sphere of horizon named $L$. We show that for the apparent horizon the first law is roughly respected for different epochs while the second laws of thermodynamics is respected while for $L$ as the system's IR cut-off first law is broken down and second law is respected for special range of deceleration parameter. It is also shown that at late-time universe $L$ is equal to $R_A$ and the thermodynamic laws are hold, when the universe has non-vanishing curvature. Defining the fluid temperature to be proportional to horizon temperature the range for coefficient of proportionality is obtained provided that the generalized second law of thermodynamics is hold.

description: Interaction between an antibody (Ab) and its antigen (Ag) plays a vital role in the immune response and is regulated by precise structural determinants. Knowledge of the epitope, i.e. the antigen region recognized by the Ab, is fundamental in order to study the mode of action of Ab and to engineer therapeutic antibodies with desired binding and affinity properties.

In this work, we present an innovative approach for in silico identification of epitopes. By using the Ag-Ab cases of the protein-protein benchmark v5 (Vreven et al. JMB 2015), we docked the unbound structures with ZDOCK (Chen et al. Proteins 2003). We then evaluate the frequency with which every Ag-residue is in contact with any Ab-residue within the pool of the docked models, in order to identify residues forming the epitope.

With our approach, we are able to identify the epitope (or part of it) in 80% of the cases and we consistently rank native-like models within the top 10 positions (CONSRANK approach, Oliva et al, Proteins 2013). Importantly, our approach results very robust when real-case scenarios are considered, i.e. when only a model of the Ab can be used, with the unbound structure of the Ag.

description: We present a model-independent anatomy of the $ΔF=2$ transitions $K^0-\bar K^0$, $B_{s,d}-\bar B_{s,d}$ and $D^0-\bar D^0$ in the context of the Standard Model Effective Field Theory (SMEFT). We present two master formulae for the mixing amplitude $\big[M_{12} \big]_\text{BSM}$. One in terms of the Wilson coefficients (WCs) of the Low-Energy Effective Theory (LEFT) operators evaluated at the electroweak scale $μ_\text{ew}$ and one in terms of the WCs of the SMEFT operators evaluated at the BSM scale $Λ$. The coefficients $P_a^{ij}$ entering these formulae contain all the information below the scales $μ_\text{ew}$ and $Λ$, respectively. Renormalization group effects from the top-quark Yukawa coupling play the most important role. The collection of the individual contributions of the SMEFT operators to $\big[M_{12}\big]_\text{BSM}$ can be considered as the SMEFT ATLAS of $ΔF=2$ transitions and constitutes a travel guide to such transitions far beyond the scales explored by the LHC. We emphasize that this ATLAS depends on whether the down-basis or the up-basis for SMEFT operators is considered. We illustrate this technology with tree-level exchanges of heavy gauge bosons ($Z^\prime$, $G^\prime$) and corresponding heavy scalars.

description: In the late 1960s and early 1970s, young artists Regina Vater and Cecilia Vicuña experimented with waste as artistic material, and the designation of specific spaces as “wastelands.” Typically, scholars have framed this reappropriation of waste as indicative of an ecocritical politic that revealed the environmental costs of capitalist extraction of resources and an endless cycle of consumption. In this thesis, however, I argue that both artists used garbage because of its abject qualities and its undesirable status. I trace two distinct moments in each artists’ trajectory, namely their first experimentations with trash and their renegotiation of their artistic praxis in the wake of exile. In Vater’s Magi(o)cean (1970) and Vicuña’s Casa Espiral (1966), both artists engaged with the societal desire to hide and erase the presence of trash. That erasure led them to instate an “aesthetics of garbage,” which made visible the precarious conditions of their respective home countries Brazil and Chile. Brazil’s military dictatorship was instituted in 1964, and Chile would follow suit in 1973. Because of these political shifts, Vater left for New York in 1973 and Vicuña went to London in 1972. Their lives in exile and the discomfiting experience of displacement impelled both artists to play with debris differently. In Vater’s first video work Luxo-Lixo (1973) and Vicuña’s book Saborami (1973), the artists foreground debris’ essentially fragmentary nature, inspiring a new way of working and understanding space, particularly when parsing the experience of diaspora and the violence at home. These analyses of Vater and Vicuña unpack the disjunctive spatial politics of the city and suggest that the framework of waste is a critical mode of study.

description: Astrometric noise in excess of parallax and proper motion could be a signature of orbital wobble of individual components in binary star systems. The combination of X-ray selection with astrometric noise can then be a powerful tool for identifying accreting binaries. Here, we mine the Gaia DR2 catalogue for Galactic sources with significant values of astrometric noise over the parameter space expected for known and candidate X-ray binaries (XRBs). Cross-matching our sample with the Chandra Source Catalogue CSC2.0 returns a primary sample of ~1,500 X-ray sources with significant excess noise, constituting ~0.04% of the initial Gaia sample. By contrast, the fraction of matched X-ray sources in a control sample with smaller excess noise is a factor of about 7 lower. The primary sample branches off the main sequence much more than control objects in colour-mag space, shows a distinct spatial distribution in terms of Galactic latitudes, comprises more objects with an Halpha excess and larger X-ray-to-optical flux ratios, and includes a higher fraction of known binaries, variables and young stellar object class types. However, for individual XRBs with known system parameters, excess noise can exceed expectations, especially for small wobble. It is likely that other factors (possibly attitude and modelling uncertainties, as well as source variability) currently dominate the observed noise in such systems. Confirmation must therefore await future Gaia releases. The full Chandra/Gaia matched catalogue is released here to enable legacy follow-up.

"Raising the Communist successors" : childrearing in rural China (1949-1983)

description: Raising the Communist Successors traces how the concepts and practices of caring for young children shifted in both the state initiatives and households for Chinese peasants under the commune system. It explores, focused on childcare, clashes between the state and the peasantry and the changing boundaries between the public and private spheres. As a micro history study, it focuses on Mianchi, a single county in China, and makes intensive use of grassroots sources, particularly county archives and in-person interviews. The resources and political means processed by the Party-state enabled the initiation of modern childcare facilities-nurseries and kindergartens against the harsh material conditions and the rearrangement of childcare related to who and how to take care of children inside families. These innovations triggered the transformation of the peasantry’s mindset on topics such as childhood, motherhood, family relations, women’s liberation, and the welfare state. Childcare eventually evolved from a family business to a state affair, from a childminding task to an education practice, and from a free, invisible, reproductive labor to a transactable service featuring intellectual, economic, and emotional values. It is the first systematic historical research to delve into the rural childcare issues of contemporary China. Its innovative approach lies in several aspects. First, it uses childcare, situated at a rare crossroads between the private and public spheres, as a vantage point to observe the power struggles between the state and families, an essential yet overlooked compartment for the central inquiry in the scholarship on China—the relationship between the state and society. Second, it reveals the voices of two marginalized groups in the collectivization, women and children, by reporting on their emotions, expectations, and day-to-day experiences affected by the childcare practices yet erased in a top-down narrative. Lastly, it adopts the method of cultural history, reading childcare practice as discourses. The ways of providing or enacting childcare serve as a metaphor, differentiating people and enemies, constructing advanced models, and showcasing a collective way of living.
Evaluating the collaboration towards a future vision and ecosystem objectives for the Salmon River Watershed

description: In 1995, the Salmon River Watershed Roundtable (SRWR) became a pilot project for a collaborative process to establish community-developed ecosystem objectives, (part of a larger project to develop goals, objectives and indicators of ecosystem health). This thesis evaluates the collaboration using mostly qualitative methods including document analysis, participant observation, interviews with process participants, and a survey of watershed residents. A comparison of the case study to a 5-stage model of collaboration framed the description of events, revealed parallels between the case study and the model, and placed the case study in the "structuring" stage of collaboration. Through evaluating the process from the participants' viewpoints, several conclusions were drawn. (1) The overall goal of the pilot project was achieved, community developed ecosystem objectives were established. (2) Process strengths included: wide-spread awareness and support for the project within the watershed; a clearly defined convenor role; a well organized and facilitated process which encouraged participation of people present; and the education of local residents about their watershed and their neighbours. (3) Process weaknesses or areas for improvement included: unclear roles of watershed residents and government agencies; poor attendance at community meetings; long and repetitive meetings; mistrust over the use of government funds; and scepticism about the ability of the SRWR to implement the objectives developed. Although the project cost $124,955 in contributed funding, as well as huge commitments of time and energy, most process participants thought the benefits of the process out-weighed those costs. Benefits included: anticipated improvements in ecosystem health; education of, and shared understanding among watershed stakeholders; information for use in other planning processes; and organizational direction for the SRWR. Successul elements of the case study provide a strong basis for continuing the pilot project into its next phases (developing ecosystem indicators and a monitoring program) and for cautiously attempting the process in other watersheds. Further assessments should be conducted in the future to determine the productivity of the process outcomes with respect to long term improvements in ecosystem health. Future efforts to develop ecosystem objectives should pay special attention to the cultural and social appropriateness of process methods, and power, authority and acocuntability within the process. Specific recommendations made for the SRWR regarding roles and responsibilities, communications, process, skill development and future research are also applicable to future projects. Both the federal and provincial governments have roles to play in the future promotion and development of ecosystem objectives in collaboration with local multi-stakeholder groups.
Coarse metric and uniform metric

description: We introduce the notion of coarse metric. Every coarse metric induces a coarse structure on the underlying set. Conversely, we observe that all coarse spaces come from a particular type of coarse metric in a unique way. In the case when the coarse structure $\mathcal{E}$ on a set $X$ is defined by a coarse metric that takes values in a meet-complete totally ordered set, we define the associated Hausdorff coarse metric on the set $\mathcal{P}_0(X)$ of non-empty subsets of $X$ and show that it induces the Hausdorff coarse structure on $\mathcal{P}_0(X)$. On the other hand, we define the notion of pseudo uniform metric. Each pseudo uniform metric induces a uniform structure on the underlying space. In the reverse direction, we show that a uniform structure $\mathcal{U}$ on a set $X$ is induced by a map $d$ from $X\times X$ to a partially ordered set (with no requirement on $d$) if and only if $\mathcal{U}$ admits a base $\mathcal{B}$ such that $\mathcal{B}\cup \{\bigcap \mathcal{U}\}$ is closed under arbitrary intersections. In this case, $\mathcal{U}$ is actually defined by a pseudo uniform metric. We also show that a uniform structures $\mathcal{U}$ comes from a pseudo uniform metric that takes values in a totally ordered set if and only if $\mathcal{U}$ admits a totally ordered base. Finally, a valuation ring will produce an example of a coarse and pseudo uniform metric that take values in a totally ordered set.
description: This version contains the following minor corrections to the published version: (1). The word "increasing" is added in Definition 2(c). (2). In part (a) of Theorem 5, as well as parts (c) and (e) of Proposition 8, we need to assume that the coarse metric take values in a meet complete directed set. The corrections and changes are marked in red
Does it really exist? Creating the collinear masking effect by illusory contours
Creators: name: Yun, Ting

description: Usually objects on a salient line should be easier to be found due to the obvious position these objects located. However, Jingling and Tseng (2013) discovered that when objects are arranged regularly to form a collinear line, a target on this line is harder to be found. This phenomenon is called the collinear masking effect. One possibility that creates the collinear masking effect is a filling-in process of the collinear grouping, making an illusory contour and smearing the visibility of the target. To test the conjecture, we designed several search displays formed by different illusory contours (e.g., Kaniza type and abutting line illusory contours) to examine whether the illusory contour can mask a local target. The results of three experiments showed that targets on an illusory contour actually easier to be found (i.e., faster RT and higher accuracy) than those not on illusory contours. In other words, the collinear masking effect was not due to a perceptual filling-in on illusory contours. This experiment may improve our understanding about the underlying mechanism of the collinear masking effect.

description: This study aimed to investigate the antitumor effect of ultrasmall gold nanoparticles (AuNPs), around 3 nm, stabilized by the anionic polysaccharide gum arabic (GA-AuNPs). The focus was downregulation of cancer hallmarks of aggressive tumors, using a highly metastatic model of melanoma. We first demonstrated that GA-AuNPs showed excellent stability under biological environment. Non-cytotoxic concentrations to seven different cell lines, including tumorigenic and non-tumorigenic cells, were determined by standard 2D in vitro assays. Gold concentrations below 2.4 mg L-1 were non-cytotoxic and therefore chosen for further analyses. Cells exposed to GA-AuNPs were uptaken by melanoma cells through endocytic processes. Next, we described remarkable biological properties using non-cytotoxic concentrations of this nanomaterial. Invasion through an extracellular matrix barrier as well as 3D growth capacity (anchorage-independent colony formation and spheroids growth) were negatively affected by 2.4 mg L-1 GA-AuNPs. Additionally, exposed spheroids showed morphological changes, suggesting that GA-AuNPs could penetrate into the preformed tumor and affect its integrity. All together these results demonstrate that side effects, such as cytotoxicity, can be avoided by choosing the right concentration, nevertheless, preserving desirable effects such as modulation of key tumor cell malignancy features.
