description: We examine magnetic domain patterns in symmetric [Co/Ni]$_M$ and asymmetric [Pt/(Co/Ni)$_M$/Ir]$_N$ multi-layers using Fresnel mode Lorentz transmission electron microscopy (LTEM). In the symmetric multi-layer, where the Dzyaloshinskii-Moriya Interaction is expected to be zero, we observe purely Bloch type domain walls with no preferred chirality. In the asymmetric multi-layers, where significant interfacial DMI is present, we observe domain patterns with chiral Néel domain walls, which evolve into sub-100nm isolated Néel Skyrmions with the application of a perpendicular field. The impact of layer thickness and film stack on interfacial magnetic properties is discussed in the context of developing a tunable multi-layer system for future spintronic applications.

The Phenomenology of LIGHT: an interpretation of Stockhausen's opera cycle drawing on Heidegger's Fourfold and Lacanian psychoanalysis

Subjects: subject: 190409 Musicology and Ethnomusicology
subject: FOS: Arts (arts, history of arts, performing arts, music)

description: This thesis offers a new interpretation on the music and symbolism of the seven-part opera cycle LICHT (LIGHT), composed by Karlheinz Stockhausen from 1977-2003. It is an interpretation that moves away from conventional theologically-oriented approaches and instead examines LICHT as commentary on the human search to understand the meaning and purpose of its existence. In doing this, the thesis draws on the philosophy of Martin Heidegger and the psychoanalysis of Jacques Lacan, ultimately proposing LICHT as an optimistic representation of the human condition, continually growing through its ongoing search to reach and grasp that which lies beyond it.

description: Both physical and dynamical properties must be considered to constrain the origins of the dynamically excited distant Solar System populations. We present high-precision (g-r) colors for 25 small (Hr>5) dynamically excited Trans-Neptunian Objects (TNOs) and centaurs acquired as part of the Colours of the Outer Solar System Origins Survey (Col-OSSOS). We combine our dataset with previously published measurements and consider a set of 229 colors of outer Solar System objects on dynamically excited orbits. The overall color distribution is bimodal and can be decomposed into two distinct classes, termed `gray' and `red', that each has a normal color distribution. The two color classes have different inclination distributions: red objects have lower inclinations than the gray ones. This trend holds for all dynamically excited TNO populations. Even in the worst-case scenario, biases in the discovery surveys cannot account for this trend: it is intrinsic to the TNO population. Considering that TNOs are the precursors of centaurs, and that their inclinations are roughly preserved as they become centaurs, our finding solves the conundrum of centaurs being the only outer Solar System population identified so far to exhibit this property (Tegler et al. 2016). The different orbital distributions of the gray and red dynamically excited TNOs provide strong evidence that their colors are due to different formation locations in a disk of planetesimals with a compositional gradient.

The Origin of Gravity in the Solid Vacuum
Creators: name: Kim, Min Tae

Subjects: Astrophysics

description: In modern physics gravity is still an unknown physical phenomenon. We sought to find its origin from a new concept of vacuum: Vacuum is composed of very dense solid medium with a regular matrix, where matter is vibration energy added to the vacuum matrix. This vibration radiates “matter wave”, distorting the matrix locally. Three dimensional symmetry of distortion develops around the stationary matter. Any inertial movement is interpreted as the movement of the vibration site, through which the symmetry of distortion is broken, which in turn sustains the inertial movement so that the kinetic energy is preserved. If the movement is spherically symmetric, like random vibration of a lattice point, this attraction is also spherically symmetric. This is the origin of gravity in the vacuum matrix.

description: Two-dimensional transition metal trichalcogenides (TMTC's) feature covalently bonded metal-chalcogen layers separated by the van der Waals (vdW) gap. Similar to transition metal dichalcogenides (TMDCs), TMTCs often host charge density waves (CDWs) and superconductivity but unlike TMDCs atomic chains in the crystal structure give rise to quasi one-dimensional (quasi 1D) conduction. ZrTe$_3$ features CDW below $T_{\textrm{CDW}}$ = 63 K and filamentary superconductivity below 2 K that can be enhanced by pressure or chemical substitution. Here we report the presence of mixed valent Zr$^{2+}$ and Zr$^{4+}$ atoms in ZrTe$_3$ crystals that is reduced by doping in ZrTe$_{3-x}$Se$_x$ and Zr$_{1-y}$Hf$_y$Te$_3$. Superconductivity is enhanced via disorder in Te2-Te3 atomic chains that are associated with CDW formation. Hf substitution on Zr atomic site enhances $T_{\textrm{CDW}}$ due to unperturbed Te2-Te3 chain periodicity and enhanced electron-phonon coupling. Weak electronic correlations in ZrTe$_{3-x}$Se$_x$ are likely governed by the lattice contraction effects.

description: For taxonomic levels higher than species, the abundance distributions of number of subtaxa per taxon tend to approximate power laws, but often show strong deviationns from such a law. Previously, these deviations were attributed to finite-time effects in a continuous time branching process at the generic level. Instead, we describe here a simple discrete branching process which generates the observed distributions and find that the distribution's deviation from power-law form is not caused by disequilibration, but rather that it is time-independent and determined by the evolutionary properties of the taxa of interest. Our model predicts-with no free parameters-the rank-frequency distribution of number of families in fossil marine animal orders obtained from the fossil record. We find that near power-law distributions are statistically almost inevitable for taxa higher than species. The branching model also sheds light on species abundance patterns, as well as on links between evolutionary processes, self-organized criticality and fractals.

description: We report on infrared reflectivity measurements of the $ab$-plane response of superconducting Bi$_2$Sr$_2$CuO$_6$ single crystals. The frequency dependent conductivity has a maximum near 700 cm$^{-1}$ at room temperature, which shifts to lower frequency and merges with a Drude-peak below 100 K. We attribute the unusual behaviour of the mid-infrared conductivity to low frequency transitions between electronic bands of mainly BiO character near the $\overline{M}$ point. The linear temperature dependence of the low-frequency resistivity can be followed down to approximately 40 K where it saturates.

description: Merging short-exposure frames can provide an image with reduced noise in low light conditions. However, how best to align images before merging is an open problem. To improve the performance of alignment, we propose an inertia-sensor aided algorithm for smartphone burst photography, which takes rotation and out-plane relative movement into account. To calculate homography between frames, a three by three rotation matrix is calculated from gyro data recorded by smartphone inertia sensor and three-dimensional translation vector are estimated by matched feature points detected from two frames. The rotation matrix and translations are combined to form the initial guess of homography. An unscented Kalman filter is utilized to provide a more accurate homography estimation. We have tested the algorithm on a variety of different scenes with different camera relative motions. We compare the proposed method to benchmark single-image and multi-image denoising methods with favorable results.

description: Abstract: The rich linguistic, ethnic and cultural diversity of Ethiopia provides an unprecedented opportunity to understand the level to which cultural factors correlate with–and shape–genetic structure in human populations. Using primarily new genetic variation data covering 1,214 Ethiopians representing 68 different ethnic groups, together with information on individuals’ birthplaces, linguistic/religious practices and 31 cultural practices, we disentangle the effects of geographic distance, elevation, and social factors on the genetic structure of Ethiopians today. We provide evidence of associations between social behaviours and genetic differences among present-day peoples. We show that genetic similarity is broadly associated with linguistic affiliation, but also identify pronounced genetic similarity among groups from disparate language classifications that may in part be attributable to recent intermixing. We also illustrate how groups reporting the same culture traits are more genetically similar on average and show evidence of recent intermixing, suggesting that shared cultural traits may promote admixture. In addition to providing insights into the genetic structure and history of Ethiopia, we identify the most important cultural and geographic predictors of genetic differentiation and provide a resource for designing sampling protocols for future genetic studies involving Ethiopians.

description: Abstract: Background: The vascular endothelium has important endocrine and paracrine roles, particularly in the regulation of vascular tone and immune function, and it has been implicated in the pathophysiology of a range of cardiovascular and inflammatory conditions. This study uses a series of transgenic murine models to explore for the first time the role of the hypoxia-inducible factors, HIF-1α and HIF-2α in the pulmonary and systemic circulations as potential regulators of systemic vascular function in normoxic or hypoxic conditions and in response to inflammatory stress. We developed a series of transgenic mouse models, the HIF-1α Tie2Cre, deficient in HIF1-α in the systemic and pulmonary vascular endothelium and the L1Cre, a pulmonary endothelium specific knockout of HIF-1α or HIF-2α. In vivo, arterial blood pressure and metabolic activity were monitored continuously in normal atmospheric conditions and following an acute stimulus with hypoxia (10%) or lipopolysaccharide (LPS). Ex vivo, femoral artery reactivity was assessed using wire myography. Results: Under normoxia, the HIF-1α Tie2Cre mouse had increased systolic and diastolic arterial pressure compared to litter mate controls over the day–night cycle under normal environmental conditions. VO2 and VCO2 were also increased. Femoral arteries displayed impaired endothelial relaxation in response to acetylcholine mediated by a reduction in the nitric oxide dependent portion of the response. HIF-1α L1Cre mice displayed a similar pattern of increased systemic blood pressure, metabolic rate and impaired vascular relaxation without features of pulmonary hypertension, polycythaemia or renal dysfunction under normal conditions. In response to acute hypoxia, deficiency of HIF-1α was associated with faster resolution of hypoxia-induced haemodynamic and metabolic compromise. In addition, systemic haemodynamics were less compromised by LPS treatment. Conclusions: These data show that deficiency of HIF-1α in the systemic or pulmonary endothelium is associated with increased systemic blood pressure and metabolic rate, a pattern that persists in both normoxic conditions and in response to acute stress with potential implications for our understanding of the pathophysiology of vascular dysfunction in acute and chronic disease.
A low-order nonconforming method for linear elasticity on general meshes

description: In this work we construct a low-order nonconforming approximation method for linear elasticity problems supporting general meshes and valid in two and three space dimensions. The method is obtained by hacking the Hybrid High-Order method, that requires the use of polynomials of degree $k\ge1$ for stability. Specifically, we show that coercivity can be recovered for $k=0$ by introducing a novel term that penalises the jumps of the displacement reconstruction across mesh faces. This term plays a key role in the fulfillment of a discrete Korn inequality on broken polynomial spaces, for which a novel proof valid for general polyhedral meshes is provided. Locking-free error estimates are derived for both the energy- and the $L^2$-norms of the error, that are shown to convergence, for smooth solutions, as $h$ and $h^2$, respectively (here, $h$ denotes the meshsize). A thorough numerical validation on a complete panel of two- and three-dimensional test cases is provided.

The entropy bound follows from application of the generalized second law of thermodynamics to an idealized gedanken experiment in which an entropy-bearing rotating system falls into a black hole. This bound is stronger than the Bekenstein entropy bound for non-rotating systems.

description: Abstract: Ketamine is a valuable anaesthetic and analgesic that in recent years has gained notoriety as a recreational drug. Recently, ketamine has also been proposed as a novel treatment for depression and post-traumatic stress disorder. Beyond its anaesthetic actions, however, the effects of ketamine on brain activity have rarely been probed. Here we examined the cortical electroencephalography (EEG) response to ketamine of 12 sheep. Following ketamine administration, EEG changes were immediate and widespread, affecting the full extent of the EEG frequency spectrum measured (0–125 Hz). After recovery from sedation during which low frequency activity dominated, the EEG was characterised by short periods (2–3 s) of alternating low (<14 Hz) and high (>35 Hz) frequency oscillation. This alternating EEG rhythm phase is likely to underlie the dissociative actions of ketamine, since it is during this phase that ketamine users report hallucinations. At the highest intravenous dose used (24 mg/kg), in 5/6 sheep we observed a novel effect of ketamine, namely the complete cessation of cortical EEG activity. This persisted for up to several minutes, after which cortical activity resumed. This phenomenon is likely to explain the ‘k-hole’, a state of oblivion likened to a near death experience that is keenly sought by ketamine abusers.

description: Genus Preptychostomum Puytorac, 1968a
 Preptychostomum ciliates are usually globular in shape. They are characterized by a large oral cavity, an anterior bare area more or less developed without skeletal fibers. The elongated macronucleus perpendicular to the anteroposterior axis of the cell is surmounted by a bulky micronucleus. There is the presence of a posterior pulsatile vacuole. In the genus Preptychostomum, we describe a new species: P. donedaensis n. sp.

description: This work proposes a novel logic device (SkyLogic) based on skyrmions, which are magnetic vortex-like structures that have low depinning current density and are robust to defects. A charge current sent through a polarizer ferromagnet (P-FM) nucleates a skyrmion at the input end of an intra-gate FM interconnect with perpendicular magnetic anisotropy (PMA-FM). The output end of the PMA--FM forms the free layer of an MTJ stack. A spin Hall metal (SHM) is placed beneath the PMA-FM. The skyrmion is propagated to the output end of the PMA-FM by passing a charge current through the SHM. The resistance of the MTJ stack is low (high) when a skyrmion is present (absent) in the free layer, thereby realizing an inverter. A framework is developed to analyze the performance of the SkyLogic device. A circuit-level technique is developed that counters the transverse displacement of skyrmion in the PMA-FM and allows use of high current densities for fast propagation. The design space exploration of the PMA-FM material parameters is performed to obtain an optimal design point. At the optimal point, we obtain an inverter delay of 434 ps with a switching energy of 7.1 fJ.

Assessing the Intrinsic Uncertainty and Structural Stability of Planetary Models: 1) Parameterized Thermal-Tectonic History Models

description: Thermal history models, that have been used to understand the geological history of Earth, are now being coupled to climate models to map conditions that allow planets to maintain surface water over geologic time - a criteria considered crucial for life. However, the lack of intrinsic uncertainty assessment has blurred guidelines for how thermal history models can be used toward this end. A model, as a representation of something real, is not expected to be complete. Unmodeled effects are assumed to be small enough that the model maintains utility for the issue(s) it was designed to address. The degree to which this holds depends on how unmodeled factors affect the certainty of model predictions. We quantify this intrinsic uncertainty for several parameterized thermal history models (a widely used subclass of planetary models). Single perturbation analysis is used to determine the reactance time of different models. This provides a metric for how long it takes low amplitude, unmodeled effects to decay or grow. Reactance time is shown to scale inversely with the strength of the dominant feedback (negative or positive) within a model. A perturbed physics analysis is then used to determine uncertainty shadows for model outputs. This provides probability distributions for model predictions and tests the structural stability of a model. That is, do model predictions remain qualitatively similar, and within assumed model limits, in the face of intrinsic uncertainty. Once intrinsic uncertainty is accounted for, model outputs/predictions and comparisons to observational data should be treated in a probabilistic way.

Reaching Toward the Outside: Saussure, Hjelmslev and Cinema Semiosis
Creators: name: Walldén, Rea
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2012

description: The present paper investigates the ways through which semiosis in general and cinematic semiosis in particular reach toward the "exo-semiotic" realm. It attempts a meta-semiotic and epistemological approach, based on Ferdi­nand de Saussure's tradition of semiotics, and particularly on Louis Hjelsmlev's model of the sign-function, as introduced in his 1954 essay "La strat­ification du langage". It investigates the sign-function's relations to its ref­erent and to its expressive materials, and then attempts to apply Hjelmslev's model to cinema. I hope to achieve the double aim of re-situating some lin­gering debates in cinema theory, while also exemplifying some questions regarding semiosis in general. The paper starts by summarizing the main axes of Saussure's definition of the sign and its formalisation by Hjelmslev. It then shows how the de-essentialisation of semiosis leads to significant re-arrangements of the tradi­tional premises with regards to the sign's relation to both the referent and the expressive medium. Finally, it surveys the central issues that formed the discipline of the semiotics of cinema, stressing the conventionality of the cinema sign-function and the heterogeneity of its expression-plane. The paper thus shows that Saussure's and Hjelmslev's insights with regard to general semiotics can assist in untangling theoretical misunderstandings with regard to how cinema functions, while understanding cinematic semiosis can contribute to deepening and enriching our understanding of the function of semiosis in general.

Are We Always Translating Signs Whether We Know It or Not?

Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2012

description: This paper is an extended review-and-discussion of Professor Dinda Gorlee's recent book Wittgenstein in Translation: Exploring Semiotic Signa­tures. Professor Gorlee's volume focuses on Ludwig Wittgenstein's frag­ments, many of which ended up in enticingly interconnected books prima­rily edited by others, and Charles S. Peirce's stops and starts ending in mounds of unpublished papers, a fraction of which have found their way between book covers. Both authors challenge whoever might venture to translate them, especially when they have so much to say on vague and un­certain interpretations, which is to say, translations.

Biblical Windows
Creators: name: Almalech, Mony
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2012

description: This paper examines different translations of the Bible from Hebrew, a Se­mitic language, into Indo-European languages, using the methodology of root semantics and focusing on the Hebrew terms translated into English as "window". Analysing the semantics of the roots of the Hebrew terms, we discover that in addition to the concept of "window" as an opening in a wall, they also have varying significations of whiteness, light, prophecy, purity, judgment, cleansing, and blessing. All the Hebrew terms are tra­versed by the idea of light and purity, and also display different transfor­mations of the idea of light, meanings which are lost in translation into Indo-European languages. The theoretical implication is that there are in Biblical Hebrew meanings that never pass to the Indo-European transla­tions, because the Hebrew language is the vehicle of a worldview totally different from that of the Indo-European languages.

Semantic Isotopies in Interlingual Translation: Towards a Cultural Approach
Creators: name: Kourdis, Evangelos
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2012

description: This paper discusses the interlingual translation of utterances based on the notion of semantic isotopy, as developed by Algirdas Julien Greimas who, since the late 1960s, has been the central figure in the Paris School of Semi­otics. More precisely, I will examine utterances such as film titles and newspaper titles translated from French into English and Greek, in order to demonstrate how isotopies are translated and, in essence, how cultural elements are reflected in the translation process. The study aims at enhanc­ing a theoretical understanding of the cultural function of translation, an understanding also based on certain semiotic parameters such as intertextual elements and connotation reservation or equivalence.

description: Various countries around the world are experiencing instability. Each country has its own set of circumstances. Efforts are being made all over the world to limit or stop them. Nigeria, as a developing nation, is not exempt. Efforts are also being made to lessen the danger. This paper aims to identify one of the areas in which Nigeria is severely impacted, namely environmental insecurity. The articles collected from the internet were used in this review paper. Over 100 references were found, but only a few that were important to this project were used. There is no question that environmental insecurity exists in the areas of air (epidemics, noise, ozone depletion, and climate change), water (oil spills, plastic waste, freshwater contamination, and acid rain), and soil (land degradation, erosion, deforestation, desertification, biodiversity). For Nigeria to be environmentally stable, the approved blueprint of the 2030 Agenda for Sustainable Development (SDG) must be strictly pursued
Everyday Practices and Subversions: Semiotic Analysis of the 2009 Greek Elections Through the Headlines of a Daily National Newspaper
Creators: name: Chalevelaki, Maria
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2012

description: In this article, we will examine how journalistic discourse interferes with everyday practice and contributes to its subversion. We will show how the special event of national elections, once it becomes everyday itself, can still attract the interest of readers, interrupting the rhythm of habit. More specifically, through selected headlines of the newspaper Eleftherotypia we will examine how the 2009 national elections in Greece, forming a strong political event, tended to become routine through the daily flow of the press and how the enunciative strategies of the newspaper attempted to maintain the intensity of its readers' interest in this particular topic.

Remix Semiosis as Ideology Critique: A Visual Semiotic Study of Critical Remix Video
Creators: name: Gallagher, Owen
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2012

description: Critical Remix Video (CRV) has become a potentially powerful and per­suasive alternative to mainstream commercial advertising. Many producers of such work seek to convince audiences that dominant media messages communicate inherently false ideological meanings by exposing contra­dictions and hypocrisies in these messages. However, CRVs themselves communicate equally contradictory ideological meanings in employing techniques of media manipulation, deception and censorship in their design. This study interrogates and deconstructs the visual signs in CRVs and ex­plores the role and influence of ideology in the construction of meanings communicated to online audiences by such work. The findings of this in­quiry should increase our understanding of how CRVs are constructed and why they are produced and enable future producers to improve the efficacy of subsequent iterations by revealing the inherent weaknesses in the current state of the art. A visual semiotic analysis of a representative sample of CRVs was carried out which found that in the process of unmasking the ideology in the subject of its critique, each CRV formulated a counter-ide­ology and made truth-claims that are equally susceptible to subsequent cri­tique. Inadvertently, CRVs enable us to see more clearly that claims to truth, whether received through mainstream or alternative channels, cannot be accepted at face value and must be critically evaluated and considered in relation to the relative positions of the senders and receivers of the mes­sages. Despite such dilemmas, CRVs represent an authentic opportunity for grassroots activist filmmakers to have their voices heard on a global stage, utilizing the full potential of digital networking and mobile technolo­gies as well as spreadable media content and online distribution platforms.

description: Nematodes have evolved to swim in highly viscous environments. Artificial mechanisms that mimic the locomotory functions of nematodes can be efficient viscous pumps. We experimentally simulate the motion of the head segment of Caenorhabditis elegans by introducing a reciprocating and rocking blade. We show that the bio-inspired blade's motion not only induces a flow structure similar to that of the worm, but also mixes the surrounding fluid by generating a circulatory flow. When confined between two parallel walls, the blade causes a steady Poiseuille flow through closed circuits. The pumping efficiency is comparable with the swimming efficiency of the worm. If implanted in a sealed chamber and actuated remotely, the blade can provide pumping and mixing functions for microprocessors cooled by polymeric flows and microfluidic devices.
