description: We studied the influence of heating effects in an organic device containing a layer sequence of n-doped / intrinsic / n-doped C60 between crossbar metal electrodes. A strong positive feedback between current and temperature occurs at high current densities beyond 100 A/cm2, as predicted by the extended Gaussian disorder model (EGDM) applicable to organic semiconductors. These devices give a perfect setting for studying the heat transport at high power densities because C60 can withstand temperatures above 200° C. Infrared images of the device and detailed numerical simulations of the heat transport demonstrate that the electrical circuit produces a superposition of a homogeneous power dissipation in the active volume and strong heat sources localized at the contact edges. Hence, close to the contact edges, the current density is significantly enhanced with respect to the central region of the device, demonstrating that three-dimensional effects have a strong impact on a device with seemingly one-dimensional transport.
The Pennsylvanian Lower Strawn Group, Jack and Wise Counties, Fort Worth Basin : facies distribution and stratigraphic architecture

description: The Lower Strawn Group in Jack and Wise counties of the Fort Worth Basin are laterally and vertically heterogeneous deltaic deposits comprising sandstones, siltstones, and shales with thin, discontinuous carbonates and coal seams reflecting variable icehouse condition controls. Given a general lack of differentiation of individual sequences in the Lower Strawn in Jack and Wise counties, this study develops a stratigraphic framework, highlights relationships between component facies of the Lower Strawn, establishes individual sequences, and identifies depositional controls and their effects on reservoir predictability. With an estimated 38 million barrels of oil (MMBO) & 56 billion cubic feet of gas (BCF) of mean total undiscovered resources located in Pennsylvanian/Permian fluvio-deltaic sandstones and conglomerates, analogous to depositional environments in many foreland basins globally, this study provides a key dataset with respect to component depositional facies and reservoir architecture for more informed resource assessment. Based on core description and interpretation, depositional environments of the Lower Strawn Group include prodelta, medial delta front, interdistributary-bay, channel mouth bar, and distributary-channel deposits. These interpreted depositional environments, their well-log pattern, and vertical facies relationships enable an interpretation that fluvio-deltaic depositional systems dominated in the Lower Strawn Group. Wireline log correlations of regionally-extensive maximum flooding surfaces were used to develop a sequence stratigraphic framework that identified eleven regressive-transgressive, fluvio-deltaic sequences averaging 90-240ft thick, collectively spanning a thickness of 1,000-2,700 ft. (305-823 m.) as the interval onlapped the forebulge of the Fort Worth Foreland Basin. A south-southwest overall direction of progradation was identified based on the distribution of net sandstone thickness trends. The depocenters contained within these sequences reflect similar geometries to those described from fluvio-deltaic systems of the Mississippi River and Yukon River Deltas. With elevated porosity trends found to be associated with homogeneous channel-mouth bar and distributary-channel deposits, a better understanding of internal reservoir characteristics and distribution helps improve predictability for operators pursuing complex stratigraphy containing hydrocarbon resources in similar depositional settings.

description: This study discusses credibility of both the traditional and social media from the audience perspective. Numerous definitions and conceptualisations of media credibility
are either source or medium based but there are also numerous measurements made on the concept that gave rise to varied findings. An attempt was made to associate the concept of credibility with media exposure, postulating that the greater use of media would mean greater credibility. Two studies were made involving a total of 4095
respondents with 1544 questionnaires distributed in April 2019, and 2551questionnaires in January 2018 to investigate the concept of credibility and its correlate with media use. The first period was before the General Elections but the April 2019 study was made after the May General Election giving an idea how credibility could have changed under a new government. The results of this study revealed that Malaysians perceived the traditional media, including TV, radio, and newspapers, were more credible than the new media (internet, online news portals, Facebook, and
Twitter). TV was perceived to have the highest credibility, while Twitter, the lowest credibility. The social media suffered low credibility due to the surrounding discussions
on fake news, false information, and post-truth issues. The sources of content in the traditional media are mostly known or verified, unlike that of the new media, thus paving for the poor evaluation of credibility of the new media.

description: Detecting community structure in social networks is a fundamental problem empowering us to identify groups of actors with similar interests. There have been extensive works focusing on finding communities in static networks, however, in reality, due to dynamic nature of social networks, they are evolving continuously. Ignoring the dynamic aspect of social networks, neither allows us to capture evolutionary behavior of the network nor to predict the future status of individuals. Aside from being dynamic, another significant characteristic of real-world social networks is the presence of leaders, i.e. nodes with high degree centrality having a high attraction to absorb other members and hence to form a local community. In this paper, we devised an efficient method to incrementally detect communities in highly dynamic social networks using the intuitive idea of importance and persistence of community leaders over time. Our proposed method is able to find new communities based on the previous structure of the network without recomputing them from scratch. This unique feature, enables us to efficiently detect and track communities over time rapidly. Experimental results on the synthetic and real-world social networks demonstrate that our method is both effective and efficient in discovering communities in dynamic social networks.

description: We study the propagation of few-cycle optical solitons in nonlinear media with an anomalous, but otherwise arbitrary, dispersion and a cubic nonlinearity. Our theory extends beyond the slowly varying envelope approximation. The optical field is derived directly from the Maxwell equations under the assumption that generation of the third harmonic is a non-resonant process or at least cannot destroy the pulse prior to inevitable linear damping. The solitary wave solutions are obtained numerically up to nearly single-cycle duration using a modification of the spectral renormalisation method originally developed for the envelope solitons.

description: Motivated by recent observational constraints on dust reprocessed emission in star forming galaxies at $z\sim 6$ and above we use the very-large cosmological hydrodynamical simulation \bluetides\ to explore predictions for the amount of dust obscured star formation in the early Universe ($z>8$). \bluetides\ matches current observational constraints on both the UV luminosity function and galaxy stellar mass function and predicts that approximately $90\%$ of the star formation in high-mass ($M_{*}>10^{10}\,{\rm M_{\odot}}$) galaxies at $z=8$ is already obscured by dust. The relationship between dust attenuation and stellar mass predicted by \bluetides\ is consistent with that observed at lower redshift. However, observations of several individual objects at $z>6$ are discrepant with the predictions, though it is possible their uncertainties may have been underestimated. We find that the predicted surface density of $z\ge 8$ sub-mm sources is below that accessible to current {\em Herschel}, SCUBA-2, and ALMA sub-mm surveys. However, as ALMA continues to accrue additional surface area the population of $z>8$ dust-obscured galaxies may become accessible in the near future.

Especially after the launch of the X-ray missions ROSAT and ASCA, Narrow-Line Seyfert 1s have become very popular. In these proceedings I will give an overview of how they are distributed over the electromagnetic spectrum. I will describe what we know about them at radio, infrared, optical, and X-ray bands, and how they differ and how they are similar to Broad-Line Seyfert 1s.

description: The El Niño-Southern Oscillation (ENSO) is the leading mode of interannual (>1-9 year) climate variability and has far-reaching impacts on global temperature and rainfall patterns. That said, the instrumental record of ENSO does not have the temporal coverage necessary to characterize the full range of natural variability. Uncertainties about how ENSO variability may change in the future with anthropogenic warming motivates the study of past climate conditions when the Earth experienced different climate conditions compared to the warm, rapidly changing climate of today. Climate scientists use two primary tools to study past climate. First, general circulation models use mathematical equations based on physical principles to simulate different aspects of the climate system, including the ocean, atmosphere, land, and ice sheets. Second, various geological archives like corals, cave stalagmites and lake and ocean sediment also provide clues about how the climate varied in the past. The paleoclimate proxy records generated from geological archives thus provide independent validation of paleoclimate model simulations. Geochemical proxy records from corals are particularly well-suited for investigating past (paleo) ENSO variability as corals can provide decades to hundreds of years of climate information from the tropics at sub-annual resolution. This dissertation seeks to quantify changes in paleo-ENSO variability using geochemical proxies from corals. I first generate replicated coral records from Vanuatu in the southwest Pacific to investigate the range of ENSO variability during the 20th century and ~900 years during a time interval called the Medieval Climate Anomaly. The paleo-temperature records are based on the ratio of strontium to calcium (Sr/Ca) of massive Porites corals from Vanuatu. Next, I develop various computational algorithms to investigate how different uncertainties inherent to the coral archive impact the ability of a coral to capture changes in ENSO variability. The algorithms incorporate the impact of variable growth rates, analytical and calibration errors, and age model assumptions, and are collectively referred to a coral proxy system model (PSM). The utility of the coral PSM is demonstrated using unforced climate model output for the last millennium. I then use the PSM and apply the analytical techniques developed in the first two projects to investigate simulated and coral proxy-inferred changes in paleo-ENSO variability during the Holocene (11.65 thousand years ago to the present). The resulting model-data comparison provides a new perspective on long-term changes in ENSO variability.

description: We propose that the four-velocity of a Dirac particle is related to its relativistic wave function by $u^i=\barψγ^iψ/\barψψ$. This relativistic wave$-$particle duality relation is demonstrated for a free particle related to a plane wave in a flat spacetime. For a curved spacetime with torsion, the momentum four-vector of a spinor is related to a generator of translation, given by a covariant derivative. The spin angular momentum four-tensor of a spinor is related to a generator of rotation in the Lorentz group. We use the covariant conservation laws for the spin and energy$-$momentum tensors for a spinor field in the presence of the Einstein$-$Cartan torsion to show that if the wave satisfies the curved Dirac equation, then the four-velocity, four-momentum, and spin satisfy the classical Mathisson$-$Papapetrou equations of motion. We show that these equations reduce to the geodesic equation. Consequently, the motion of a particle guided by the four-velocity in the pilot-wave quantum mechanics coincides with the geodesic motion determined by spacetime. We also show how the duality and the operator form of the Mathisson$-$Papapetrou equations arise from the covariant Heisenberg equation of motion in the presence of torsion.

description: This note is concerned with a nonlinear diffusion problem of phase-field type, consisting of a parabolic system of two partial differential equations, complemented by Neumann homogeneous boundary conditions and initial conditions. The system arises from a model of two-species phase segregation on an atomic lattice [Podio-Guidugli 2006]; it consists of the balance equations of microforces and microenergy; the two unknowns are the order parameter $rho$ and the chemical potential $mu$. Some recent results obtained for this class of problems is reviewed and, in the case of a nonconstant and nonlinear atom mobility, uniqueness and continuous dependence on the initial data are shown with the help of a new line of argumentation developed in Colli/Gilardi/Podio-Guidugli/Sprekels 2012.

description: The main focus of this study is the coverage of New Straits Times (NST) of the first Palestinian General Elections for two presidential candidates namely, Yasser Arafat and Samiha Khalil. This study aimed to explore if any of Entman’s 1993 framing functions was used in the coverage of this issue and to explore whether the tone of NST coverage was negative, positive, balanced or neutral. To
achieve the aims of this study, qualitative content analysis of elections stories from NST has been adopted. The number of news stories was eight, and the time frame started from 19th January to 13th February 1996, where three of these stories were published on the same day of 22nd January,
two days after holding the elections on 20th January. Defining problems and diagnosing causes were
the most prominent of Entman’s four framing functions presented in all the articles. The moral judgment function was included in four news stories, and suggesting remedies was included in two news stories out of eight. The findings revealed that Yasser Arafat received 50% balanced coverage, followed by 37.5% positive coverage, and only 12.5% negative coverage, while Samiha Khalil
received 67% balanced coverage, compared to 33% positive coverage.

Western Australia

description: During the Neogene period, between 23 and 2.58 million years ago, dramatic changes in tectonic and climatic patterns affected ocean currents, sea level, and sedimentation on the continents and in the oceans. A global warm period in the early Miocene ended when ice-sheet expansion on the Antarctic continent lowered global temperatures in the middle and late Miocene. Global temperatures rebounded during the Pliocene, succeeded by a return to cooling conditions in the Pleistocene. These Neogene climatic events are important because they represent some of the best past analogues to modern and future climate change. The study of Neogene sedimentary archives therefore constitutes a research opportunity to elucidate the effects that warming climates will have on Earth’s oceans and atmosphere. The Australian continent was particularly affected by the Neogene reorganization of climate and tectonics as the northward movement of the Australian plate shifted the continent to warmer sub-tropical climates. This work reconstructs the paleoceanography and paleoclimate evolution of the Western Australian margin during the Neogene, based on detailed examination of sedimentary archives drilled by the International Ocean Discovery Program (IODP) between 2015 and 2017. Together, these cores form a latitudinal transect of Western Australia and represent the most complete Neogene stratigraphic record in the Southeast Indian Ocean. Results indicate that sedimentation patterns in both shallow and deep-water areas adapted to the displacement of the continent towards lower latitudes and were highly vulnerable to changes in Antarctic climate throughout the period. Biological productivity and aeolian input increased in the Subantarctic Ocean during the early Miocene warming as the Southern Westerlies amplified under warmer temperatures (Chapter 3). In the late Miocene, the continued opening of the Southern Ocean and the transition to colder Antarctic temperatures was accompanied by intensification of deep ocean circulation that formed extensive contourite drifts and ferromanganese crusts in the deep sea (Chapter 4). On the Northwest Shelf, a middle Miocene arid sabkha environment transitioned to a humid environment that accompanied early Pliocene warming, forming a perennial deltaic environment resulting from the southward displacement of Intertropical Convergence Zone towards northern Australia (Chapter 2). The data and interpretations presented in this dissertation shed light on the environmental impacts of changing temperatures on continental margins and on paleoenvironmental sensitivity to atmospheric CO2 forcing.

description: Beautiful formulas are known for the expected cost of random two-dimensional assignment problems, but in higher dimensions even the scaling is not known. In three dimensions and above, the problem has natural “Axial” and “Planar” versions, both of which are NP-hard. For 3-dimensional Axial random assignment instances of size n, the cost scales as Ω(1/ n), and a main result of the present paper is a linear-time algorithm that, with high probability, finds a solution of cost O(n–1+o(1)). For 3-dimensional Planar assignment, the lower bound is Ω(n), and we give a new efficient matching-based algorithm that with high probability returns a solution with cost O(n log n)

description: We propose a graph method for systematically searching for schemes that can generate multipartite entanglement in linear bosonic systems with heralding. While heralded entanglement generation offers more tolerable schemes for quantum tasks than postselected ones, it is generally more challenging to find appropriate circuits for multipartite systems. We show that our graph mapping from boson subtractions provides handy tactics to overcome the limitations in circuit designs. We present a practical strategy to mitigate the limitation through the implementation of our graph technique. Our physical setup is based on the sculpting protocol, which utilizes an $ N$ spatially overlapped subtractions of single bosons to convert Fock states of evenly distributed bosons into entanglement. We have identified general schemes for qubit N-partite GHZ and W states, which are significantly more efficient than previous schemes. In addition, our scheme for generating the superposition of $N=3$ GHZ and W entangled states illustrates that our approach can be extended to derive more generalized forms of entangled states. Furthermore, we have found an N-partite GHZ state generation scheme for qudits, which requires substantially fewer particles than previous proposals. These results demonstrate the power of our approach in discovering optimized solutions for the generation of intricate heralded entangled states. As a proof of concept, we propose a linear optical scheme for the generation of the Bell state by heralding detections. We expect our method to serve as a promising tool in generating diverse entanglement.

description: We argue that the chiral anomaly of $\Ncal = 1$ super Yang-Mills theory admits a dual description as spontaneous symmetry breaking in M theory on $G_2$ holonomy manifolds. We identify an angle of the $G_2$ background dual to the anomalous $U(1)_R$ current in field theory. This angle is not an isometry of the metric and we therefore develop a theory of ``massive isometry'' to describe fluctuations about such angles. Another example of a massive isometry occurs in the Atiyah-Hitchin metric.

description: We present a new convolution layer for deep learning architectures which we call QuadConv -- an approximation to continuous convolution via quadrature. Our operator is developed explicitly for use on non-uniform, mesh-based data, and accomplishes this by learning a continuous kernel that can be sampled at arbitrary locations. Moreover, the construction of our operator admits an efficient implementation which we detail and construct. As an experimental validation of our operator, we consider the task of compressing partial differential equation (PDE) simulation data from fixed meshes. We show that QuadConv can match the performance of standard discrete convolutions on uniform grid data by comparing a QuadConv autoencoder (QCAE) to a standard convolutional autoencoder (CAE). Further, we show that the QCAE can maintain this accuracy even on non-uniform data. In both cases, QuadConv also outperforms alternative unstructured convolution methods such as graph convolution.

description: Scattering of time-harmonic electromagnetic plane waves by a doubly periodic surface structure in R^3 can be simulated by a boundary value problem of the time-harmonic curl-curl equation. For a truncated FEM domain, non-local boundary value conditions are required in order to satisfy the radiation conditions for the upper and lower half spaces. Alternatively to boundary integral formulations, to approximate radiation conditions and absorbing boundary methods, Huber et al. [11] have proposed a coupling method based on an idea of Nitsche. In the case of profile gratings with perfectly conducting substrate, the authors have shown previously that a slightly modified variational equation can be proven to be equivalent to the boundary value problem and to be uniquely solvable. Now it is shown that this result can be used to prove convergence for the FEM coupled by truncated wave mode expansion. This result covers transmission gratings and gratings bounded by additional multi-layer systems.

description: The study has examined the similarities and differences in the coverage of two Palestinian news
agencies Ma’an and Palestinian Information Center (PIC) on the reactions of Palestinian
President Mahmoud Abbas’s regarding relocating the US embassy from Tel Aviv to Jerusalem.
The study has also aimed to explore the use of four function of framing by Entman 1993 in the
news stories of both agencies. Qualitative content analysis has been adopted to achieve the aim
of this study. The total sampling number was 9 news stories; 3 stories have been retrieved from
Ma’an, and the other 6 have been retrieved from PIC. The time frame has started from
December 5, 2017 which marked the day of informing Abbas by Trump’s decision to move the
Embassy until December 22 2017 which was a day after gaining a sweeping victory in UN by
President Abbas through a resolution that rejected the decision. Both of the news agencies were
supportive to President Abbas in their coverage and none of them has any negative coverage
about him. From the sampling number it can be seen that PIC has paid more attention for the
coverage of this issue than Ma’an. However, PIC has ignored the success of President Abbas
for achieving UN resolution against Trump’s decision. Morover, all the news stories has
included “define the problem” while excluded “diagnose causes” functions. However both
“make moral judgment” and “suggest remedies” have been included in all news stories of
Ma’an, and only half of news stories of PIC.

description: This study explores the influence of education, length of service, professionalism, and ethics on the professional values of public relations practitioners in Malaysia. A total of 427 questionnaires were distributed to public relations practitioners in Malaysia, and 322 questionnaires were
returned. The study included 61% female respondents, and 39% male respondents. The study analyzed and identified the influence of professionalism and ethics on professional values of public relations practitioners. Additionally, the study examined whether education and experience influence professional values through professionalism, and code of ethics. Six hypotheses were tested to answer the research
questions. The results from this study fully supported the hypotheses indicating that professionalism and ethics had an influence on professional values of public relations practitioners. The results also showed that education influenced both professionalism and ethics, and length of
service influenced both professionalism and ethical practice.

description: Luminous ultrasoft NLS1s and low-ionization BALQSOs share many properties, and they both represent important extremes of the active galaxy phenomenon. We briefly discuss their observational similarities as well as potential physical connections between them, concentrating on the X-ray point of view. We present several ways by which potential connections might be further tested.

The relationship between littoral drift rate and the longshore component of wave energy flux

description: Quantitative prediction of littoral drift, the longshore transport of sediment in the surf zone of beaches is highly useful in the design of coastal engineering works such as harbor entrances, groin fields, and beach nourishment programs. Two approaches have been developed to arrive at predictor equations relating the rate of littoral drift to the longshore component of incident wave energy flux. The first method requires determination of net littoral drift by survey of beach erosion or accretion in the vicinity of a jetty or other structure which is a total barrier to littoral drift and relates the rate of transport so derived to long term wave records. A second approach which relies on newly developed fluorescent tracer techniques has been developed recently by several workers. Fluorescent dyed sand is released in the surf and is sampled in a grid pattern after a short period of transport. The volume rate of littoral drift is the product of the dye centroid velocity, the width of the surf zone, and the thickness of the mobile layer of sediment. Application of density and pore space corrections provides the immersed weight rate of transport. The incident wave energy flux is determined with a recording wave gage placed outside of the surf zone, and the longshore component of the wave energy flux is determined from measurement of the angle of incidence of the waves with the beach at the wave breakpoint. This method was used for the present study. There are at present only four sets of quantitative field data on littoral drift including the data gathered in this study. Two sets have been measured by each of the above methods. Multiple regression analysis of the variables, wave energy flux, immersed weight transport rate, and mean grain diameter for the data gathered in the present study as well as the previously published data indicate that there is little or no effect of mean grain diameter on the rate of littoral drift within the sand size range. The immersed weight transport (I) is related to the longshore component of wave energy flux (P[subscript a]) by the following relationship for the Texas beaches studied. Log₁₀(I) = 0.51 Log₁₀(P[subscript a] + 2.53. A more general relationship based on all existing field data (Watts, 1953; Caldwell, 1956; Komar, 1970; and this study) is as follows: Log₁₀(I) = 0.875 Log₁₀(P[subscript a]) + 0.61. These equations can be used to compute the rate of littoral drift along any beach by applying the longshore component of wave energy flux derived either from direct wave observations or hindcast from weather records

description: This paper is concerned with the time-harmonic electromagnetic scattering problem for a finite number M of point-like obstacles in R^3. First, we give a rigorous justification of the Foldy method and describe the intermediate levels of scattering between the Born and Foldy models. Second, we study the problem of detecting the scatterers and the scattering strengths from the far-field measurements and discuss the effect of multiple scattering related to each of these models.

description: Abstract: "We shall prove the following results concerning effective reduction and conversion strategies for combinators. (1) There is an effective one-step cofinal reduction strategy (answering a question of Barendregt [2] 13.6.6). (2) There is no effective confluence function but there is an effective one-step confluence strategy (answering a question of Isles reported in [1]). (3) There is an effective one-step enumeration strategy (answering an obvious question). (4) There is an effective one-step Church-Rosser conversion strategy ('almost' answering a question of Bergstra and Klop [3])."

description: This is a study on the growth of public relations in Malaysia based on the advertisements placed in the newspapers during the colonial period. Tracing the historical development serves to make a better understanding about the nature of public relations practice. This paper therefore aims at exploring the development of the public relations profession by studying the advertisements placed in the nationwide newspapers, the Straits Times and the Singapore Free Press & Mercantile Advertiser from 1939 which included the early advertisement that contained the phrase “public relations” to 1956 a year before the independence of the Federation of Malaysia. An
analysis of the advertisements was made to fully understand the historical development of public relations in Malaya or then Malaysia.
Towards Proxemic Mobile Collocated Interactions

description: Research on mobile collocated interactions has been exploring situations where collocated users engage in collaborative activities using their personal mobile devices (e.g., smartphones and tablets), thus going from personal/individual toward shared/multiuser experiences and interactions. The proliferation of ever-smaller computers that can be worn on our wrists (e.g., Apple Watch) and other parts of the body (e.g., Google Glass), have expanded the possibilities and increased the complexity of interaction in what we term mobile collocated situations. Research on F-formations (or facing formations) has been conducted in traditional settings (e.g., home, office, parties) where the context and the presence of physical elements (e.g., furniture) can strongly influence the way people socially interact with each other. While we may be aware of how people arrange themselves spatially and interact with each other at a dinner table, in a classroom, or at a waiting room in a hospital, there are other less-structured, dynamic, and larger-scale spaces that present different types of challenges and opportunities for technology to enrich how people experience these (semi-) public spaces. In this article, the authors explore proxemic mobile collocated interactions by looking at F-formations in the wild. They discuss recent efforts to observe how people socially interact in dynamic, unstructured, non-traditional settings. The authors also report the results of exploratory F-formation observations conducted in the wild (i.e., tourist attraction).

Numerical convergence for semilinear parabolic equations

Subjects: subject: numerical analysis
subject: semilinear parabolic equation

description: We present a convergence result for finite element discretisations of semilinear parabolic equations, in which the evaluation of the nonlinearity requires some high order of regularity of the solution. For example a coefficient might depend on derivatives or pointevaluation of the solution. We do not rely on high regularity of the exact solution itself and as a payoff we can not deduce convergence rates. As an example the convergence result is applied to a nonlinear Fokker--Planck type battery model.

description: We present a program package which generates homogeneous random graphs with probabilities prescribed by the user. The statistical weight of a labeled graph $α$ is given in the form $W(α)=\prod_{i=1}^N p(q_i)$, where $p(q)$ is an arbitrary user function and $q_i$ are the degrees of the graph nodes. The program can be used to generate two types of graphs (simple graphs and pseudo-graphs) from three types of ensembles (micro-canonical, canonical and grand-canonical).
