description: For most of his adult life, John Lennon fought to define himself against his public identity as "Beatle-:John." That image, crafted by the Beatles' manager Brian Epstein and the pop music industry became a burden to all four of the Beatles during the group's seven years of international stardom. In place of the rough leather-clad rock and roll band that played rambling one hour sets in the Hamburg Kaiserkeller and the Liverpool Cavern Club during 1960-61, Epstein forged a more commercially viable group of four well (and uniformly) dressed young men whose stage act was reduced to twenty minute carefully scripted sets. Over the course of the next few years, all four of the Beatles assumed clean-cut, safe personae in accordance with the necessities of marketing the group to a broad, middle-class audience. Willing though he and the others were to take part in the group's public transfonnation, Lennon later claimed to have felt uncomfortable all along with selling out the Beatles' rock and roll roots: "What we generated was fantastic when we played straight rock, and there was nobody to touch us in Britain. But as soon as we made it, the edges were knocked off. Brian Epstein put us in suits and all that, and we made it very, very big. We sold out" (Wenner 2000:20).

description: The precessional magnetization dynamics of GaMnAs thin films are characterized by broadband network analyzer ferromagnetic resonance (FMR) in a coplanar geometry at cryogenic temperatures. The FMR frequencies are characterized as function of in-plane field angle and field amplitude. Using an extended Kittel model of the FMR dispersion the magnetic film parameters such as saturation magnetization and anisotropies are derived. The modification of the FMR behavior and of the magnetic parameters of the thin film upon annealing is analyzed.

The specimens examined in this study are smaller than those examined by Rahayu (2015), however because of the following specific characters, the identification is justified: the possession of a long antennal acicle that is overreaching the base of the fourth antennal peduncular segment; the relatively small corneas; the convex outer surface of the palm of the left cheliped that is covered with spinulose tubercles and with a strong median ridge; and the presence of a longitudinal brown stripe on the dorsal surface of the ocular peduncle.

description: In this paper we study slow-roll inflation with holonomy corrections from loop quantum cosmology. Both tensor and scalar power spectra of primordial perturbations are computed up to the first order in slow-roll parameters and $V/ρ_{c}$, where $V$ is a potential of the scalar field and $ρ_{c}$ is a critical energy density (expected to be of the order of the Planck energy density). Possible normalizations of modes at short scales are discussed. In case the normalization is performed with use of the Wronskian condition applied to adiabatic vacuum, the tensor and scalar spectral indices are not quantum corrected in the leading order. However, by choosing an alternative method of normalization one can obtain quantum corrections in the leading order. Furthermore, we show that the holonomy-corrected equation of motion for tensor modes can be derived from an effective background metric. This allows us to prove that the Wronskian normalization condition for the tensor modes preserves the classical form.

Light Energy: Our Wasted Resource

Publisher: name: Consilience

description: Artificial light at night (ALAN) is a form of visual pollution and energy waste that is often overlooked. The International Dark Sky Association estimates that 30% of all lighting is strictly for the outdoors. Furthermore, 30% of all outdoor lighting is wasted, used (1) when not needed, or (2) pointing directly upwards. In 2017, the US wasted approximately 60 billion kilowatt hours (kWh), translating to a loss of more than $6.3 billion and CO2 emissions in excess of 23 billion pounds. ALAN has been linked to reduced production of melatonin, the body’s sleep-regulating hormone, which is associated with increased risk of hormonal cancers including breast and prostate cancer. In fact, the World Health Organization (WHO) now lists shift work as a type II risk for cancer. Light at night threatens migratory birds, a majority of which fly at night presumably using constellations as their guide. Light pollution paints the sky black, pushing astronomers to ever-shrinking dark zones suitable for studying the universe. In the most severely affected cities, only a handful of stars can be seen where once thousands dazzled gazers. Society’s overreliance on ALAN has resulted in energy waste, adverse health effects, and pervasive pollution contributing to climate change and concealing our starry night sky.

Reexamining Sample Size Requirements for Multivariate, Abundance-Based Community Research: When Resources are Limited, the Research Does Not Have to Be

Community ecologists commonly perform multivariate techniques (e.g., ordination, cluster analysis) to assess patterns and gradients of taxonomic variation. A critical requirement for a meaningful statistical analysis is accurate information on the taxa found within an ecological sample. However, oversampling (too many individuals counted per sample) also comes at a cost, particularly for ecological systems in which identification and quantification is substantially more resource consuming than the field expedition itself. In such systems, an increasingly larger sample size will eventually result in diminishing returns in improving any pattern or gradient revealed by the data, but will also lead to continually increasing costs. Here, we examine 396 datasets: 44 previously published and 352 created datasets. Using meta-analytic and simulation-based approaches, the research within the present paper seeks (1) to determine minimal sample sizes required to produce robust multivariate statistical results when conducting abundance-based, community ecology research. Furthermore, we seek (2) to determine the dataset parameters (i.e., evenness, number of taxa, number of samples) that require larger sample sizes, regardless of resource availability. We found that in the 44 previously published and the 220 created datasets with randomly chosen abundances, a conservative estimate of a sample size of 58 produced the same multivariate results as all larger sample sizes. However, this minimal number varies as a function of evenness, where increased evenness resulted in increased minimal sample sizes. Sample sizes as small as 58 individuals are sufficient for a broad range of multivariate abundance-based research. In cases when resource availability is the limiting factor for conducting a project (e.g., small university, time to conduct the research project), statistically viable results can still be obtained with less of an investment.

description: Using the effective mass and rectangular potential approximations, the theory of electron dynamic conductivity is developed for the plane multilayer resonance tunnel structure placed into a constant electric field within the model of open nanosystem, and oscillator forces of quantum transitions within the model of closed nanosystem. For the experimentally produced quantum cascade laser with four-barrier active band of separate cascade, it is proven that just the theory of dynamic conductivity in the model of open cascade most adequately describes the radiation of high frequency electromagnetic field while the electrons transport through the resonance tunnel structure driven by a constant electric field.

description: Various cosmological models in frames of $F(T)$ gravity are considered. The general scheme of constructing effective dark energy models with various evolution is presented. It is showed that these models in principle are compatible with $Λ$CDM model. The dynamics of universe governed by $F(T)$ gravity can mimics $Λ$CDM evolution in past but declines from it in a future. We also construct some dark energy models with the "real" (non-effective) equation-of-state parameter $w$ such that $w\leq-1$. It is showed that in $F(T)$ gravity the Universe filled phantom field not necessarily ends its existence in singularity. There are two possible mechanisms permitting the final singularity. Firstly due to the nonlinear dependence between energy density and $H^{2}$ ($H$ is the Hubble parameter) the universe can expands not so fast as in the general relativity and in fact Little Rip regime take place instead Big Rip. We also considered the models with possible bounce in future. In these models the universe expansion can mimics the dynamics with future singularity but due to bounce in future universe begin contracts.

In particular, if $\mathcal B$ contains a non-epimorphic endomorphism, then $\rk \fix\mathcal B\leq \frac{1}{2} \rk π_1(S)$. We also show that geometric subgroups of $π_1(S)$ are inert, and hence the fixed subgroup of a family of epimorphisms of $π_1(S)$ is also inert.

description: We have measured the temperature dependence of the direct band gap, $E_g$, in SrTi$^{16}$O$_3$ and BaTiO$_3$ and related materials with quantum-paraelectric and ferroelectric properties using optical spectroscopy. We show that $E_g$ exhibits an anomalous temperature dependence with pronounced changes in the vicinity of the ferroelectric transition that can be accounted for in terms of the Fröhlich electron-phonon interaction with an optical phonon mode, the so-called soft mode. We demonstrate that these characteristic changes of $E_g$ can be readily detected even in very thin films of SrTi$^{16}$O$_3$ with a strain-induced ferroelectric order. Optical spectroscopy thus can be used as a relatively simple but sensitive probe of ferroelectric order in very thin films of these titanates and probably also in subsequent multilayers and devices.

description: This paper foregrounds notions of learning and how they are framed in transnational adaptive capacity building processes. While supporting the emergence of new adaptation governance mechanisms that recognize the boundlessness of climate change impacts, the paper draws attention to the role of learning in the process and, in particular, how learning is framed in such processes. Learning, for the most part, is framed as an event rather than a series of conscious, reflexive, adaptive and multi-layered loops. The paper argues such framings are limiting and are based on flawed conceptualization of climate adaptation as a linear process with an expected stable endpoint. Such conceptualizations, the paper further argues, fail to present the climate change phenomenon as emergence, evolving and complex and one that requires reflexive and iterative learning approaches that helps to avoid the pitfalls of managing expectations of stable

Calculations have been carried out in perturbation theory taking into account the hybridization of states for cubic, ellipsoidal, cylindrical and tetrahedral shapes by changing the volume of a quantum dot. Based on the energy calculations and on the determined wave functions of the hole states we have defined the selection rules and the dependence of the interlevel hole absorption coefficient on QD shapes and volumes.

description: Near-Infrared-spectroscopy data for V. longifolia and V. spicata using Spectral Evolution RS-3500 between 350-2500nm Premise of the study: Polyploidy has become a central factor in plant evolutionary biology in recent decades. Detecting polyploidy through methods such as flow cytometry has facilitated revealed widespread occurrence of polyploidy. Still, the inference relies on expensive lab equipment and is largely restricted to fresh or recently dried material. Methods: Here, we assess the applicability of infrared spectroscopy to infer ploidy in two related species of Veronica. Infrared spectroscopy relies on differences in absorbance of tissues, for example due to changes in primary and secondary metabolites related to polyploidy. We sampled 33 living plants from the greenhouse and 74 herbarium specimens with ploidy known through flow cytometrical measurements and analyzed the resulting spectra using Discriminant Analysis of Principal components (DAPC) and neural network (NNET) classifiers. Results: Living material of both species combined was correctly classified with 70% (DAPC) to 75% (NNET), whereas herbarium material was classified correctly with 84% (DAPC) to 85% (NNET) accuracy. Analyzing both species separately resulted in less clear results. Discussion: Infrared spectroscopy is a quite reliable but not certain method to assess intraspecific ploidy level differences in two species of Veronica. More accurate inferences rely on large training datasets and herbarium material. Thus, this study demonstrates an important way to expand the field of polyploid research to herbaria.

This study nds that carbon emissions and particulate matter air pollution are the largest environmental predictors of human capital index scores, and that the positive relationship between carbon emissions and human capital level all but disappears amongst developed nations. This study lls a gap in the literature, providing a non-geographically isolated examination of particular descriptive explanatory variables, as opposed to solely utilizing index scores.

Engineered Microenvironments for Controlled Stem Cell Differentiation

Year: 2009
Subjects: Biomedical engineering

description: In a developing organism, tissues emerge from coordinated sequences of cell renewal, differentiation, and assembly that are orchestrated by spatial and temporal gradients of multiple regulatory factors. The composition, architecture, signaling, and biomechanics of the cellular microenvironment act in concert to provide the necessary cues regulating cell function in the developing and adult organism. With recent major advances in stem cell biology, tissue engineering is becoming increasingly oriented toward biologically inspired in vitro cellular microenvironments designed to guide stem cell growth, differentiation, and functional assembly. The premise is that to unlock the full potential of stem cells, at least some aspects of the dynamic three-dimensional (3D) environments that are associated with their renewal, differentiation, and assembly in native tissues need to be reconstructed. In the general context of tissue engineering, we discuss the environments for guiding stem cell function by an interactive use of biomaterial scaffolds and bioreactors, and focus on the interplay between molecular and physical regulatory factors. We highlight some illustrative examples of controllable cell environments developed through the interaction of stem cell biology and tissue engineering at multiple levels.
Complications of the Climate Change Narrative on the Narratives of Climate Refugees
Creators: name: Mascia, Raphaella
Publisher: name: Consilience
Year: 2020

description: With projections of rapidly increasing numbers of climate refugees in the next decades, the discourse surrounding climate refugees becomes ever more pertinent within the field of sustainable development and within in the public sphere. I offer an alternative analysis of the processes which surround “knowing” and “defining” climate refugees by employing an interpretive framework which disseminates the term “narrative” according to Jean François Lyotard's The Postmodern Condition : A Report on Knowledge. In the discourse surrounding climate refugees, two main narratives interact with and dialogue with each other: the dominant climate change narrative and the narratives of climate refugees themselves. I contend that the dominant narrative of climate change complicates the narratives of climate change refugees through specific characteristics of climate change discourse specifically, the temporal characteristics of slow causality and apocalyptic themes as evinced in two case studies: Shishmaref, Alaska and the Maldives. Through researching and examining the thematic elements featured in narration, we gain a fuller comprehension of climate refugee narratives. The dominant climate change discourses permeates almost all environmental issues, and therefore, the field of sustainable development continuously confronts and interacts with such discourses. Furthermore, one such aspect of sustainable development involves the ongoing circumstances of forced migration due to climate change. Illuminating the elements of the dominant climate change narrative pervading climate refugee narratives compels us to look towards climate refugees themselves as sources for their own narratives instead permitting the dominant narratives to overshadow their experiences.

The current unprecedented outbreak of mountain pine beetle (Dendroctonus ponderosae) in lodgepole pine (Pinus contorta) forests of western Canada has resulted in a landscape consisting of a mosaic of forest stands at different stages of mortality. Within forest stands, understory communities are the reservoir of the majority of plant species diversity and influence the composition of future forests in response to disturbance. Although changes to stand composition following beetle outbreaks are well documented, information on immediate responses of forest understory plant communities is limited. The objective of this study was to examine the effects of D. ponderosae-induced tree mortality on initial changes in diversity and productivity of understory plant communities. We established a total of 110 1-m2 plots across eleven mature lodgepole pine forests to measure changes in understory diversity and productivity as a function of tree mortality and below ground resource availability across multiple years. Overall, understory community diversity and productivity increased across the gradient of increased tree mortality. Richness of herbaceous perennials increased with tree mortality as well as soil moisture and nutrient levels. In contrast, the diversity of woody perennials did not change across the gradient of tree mortality. Understory vegetation, namely herbaceous perennials, showed an immediate response to improved growing conditions caused by increases in tree mortality. How this increased pulse in understory richness and productivity affects future forest trajectories in a novel system is unknown.

description: It is shown that when a strong electric field is turned on as a background in a charged scalar field, the vacuum state of the scalar field becomes exponentially amplified. This is an analogue to gravity induced vacuum amplification, where the vacuum state becomes exponentially amplified for some geometries.

description: Using semiclassical perturbation approach in impact approximation, we have calculated Stark widths for 32 spectral lines of doubly charged argon (Ar III). Oscillator strengths are calculated using Hartree-Fock method with relativistic correction (HFR) and an atomic model including 17 configurations. Energy levels are taken from NIST database. For perturbing levels for which the corresponding energy does not exist in NIST database, the calculated energies are used. Our widths are compared with the experimental results. The results presented here are of interest for modelling and investigation of stellar atmospheres since argon in different ionization stages is observed in many astrophysical objects. Finally, the importance of Stark broadening mechanism is studied in the atmospheric conditions of sdB stars. Electron impact Stark widths are compared to thermal Doppler widths as a function of temperature and optical depth of atmospheric layers.

description: Traditional water structures such as stepwells and canal systems historically function as sustainable water sources. They are advantageous within India’s cyclic climate of flooding and drought, especially in regions of the Deccan plateau. Structures in the Deccan particularly tend to leverage laterite: a porous, geological feature specific to the region. Laterite is especially useful for collecting and maintaining water from surrounding aquifers, creating a reliable storage of water even during the dry season. Unfortunately, many of these structures have been damaged, polluted, and misused. This pilot study investigates the water quality of traditional water structures in the western Deccan Plateau region of India and their potential for revitalization. Samples were drawn from traditional water structures and domestic taps located across Central Maharashtra and Northern Karnataka. Water quality parameters were converted into a single water quality index (WQI) to characterize their current state. Qualitative site information such as degree of conservation and visible pollution level are compared via WQI. Quality amongst some traditional water structures was discovered to be comparable to domestic drinking sources, despite a lack of conservation and usage in the former. Some sites exhibited strong potential for revitalization as domestic and agricultural water sources. Finally, a detailed case study of a Karez system in Bidar outlines current characteristics, challenges, and future work in revitalizing old water structures as sustainable water sources.

description: The martensitic α --> ω transition was investigated in Ti under hydrostatic pressure. The calculations were carried out using the density functional theory (DFT) framework in combination with the Birch-Murnaghan equation of state. The calculated ground-state properties of α and ω phases of Ti, their bulk moduli and pressure derivatives are in agreement with the previous experimental data. The lattice constants of α and ω-phase at 0 K were modeled as a function of pressure from 0 to 74 GPa and 0 to 119 GPa, respectively. It is shown that the lattice constants vary in a nonlinear manner upon compression. The calculated lattice parameters were used to describe the α --> ω transition and show that the phase transition can be obtained at 0 GPa and 0 K.

description: This thesis focuses on the design, synthesis, characterization and OLED fabrication and testing of TADF emitters, with a particular emphasis on trying to achieve high horizontal orientation of their TDM. Chapter 1 explains the basic concepts behind light-matter interaction, photoluminescence, and electroluminescence, focusing on TADF materials and their use in OLEDs. An in-depth explanation of the outcoupling effect will be given, with a discussion of several literature-known strategies to achieve optimal orientation of the emitter in the OLED stack. Chapter 2 focuses on a highly oriented TADF emitter, ICzTRZ. The theoretical and optoelectronic properties and TDM orientation of the material were studied, with its most interesting feature being the nearly completely horizontal orientation of the TDM in the film. OLED performance is then discussed. Chapter 3 describes a study to try and enhance the efficiency of ICzTRZ by adopting a twin-emitter design strategy, with DICzTRZ. Due to its high molecular weight, we hypothesize that DICzTRZ could also maintain horizontal orientation in solution-processed films. Chapter 4 concludes the work on the ICz family, with a study on how the horizontal orientation of ICzTRZ derivates changes when the position and the number of tert-butyl groups on the material are modified. In Chapter 5, the knowledge gathered from the previous study on the ICz series is applied to the known randomly oriented emitter DMAC-TRZ, to try in achieving horizontal orientation of the material and therefore generate an improvement in the device efficiency. Chapter 6 continues the work on DMAC-TRZ by investigating the effect that a heteroaromatic bridge has on the photophysics of the emitter. Chapter 7 summarizes and compares the results from Chapters 2-6. A discussion of the future work and outlooks of these projects is also presented.

description: Aims: We compare the apparent difference in timing of transiting planets (or eclipsing binaries) that are observed from widely separated locations (parallactic delay). Methods: A simple geometrical argument allow us to show that the apparent timing difference depends also on the on-sky position angle of the planetary (or secondary) orbit, relative to the ecliptic plane. Results: We calculate that on-sky position angle would be readily observable using the future PLATO and CHEOPS missions data, and possibility observable already in many known radial-velocity systems (if they exhibit transits). We also find that on-sky coplanarity of multiple objects in the same system can be probed more easily than the on-sky position angle of each of the objects separately. We calculate the magnitude of the effect for all currently known planets (should they exhibit transits), finding that almost 200 of them -- mostly radial-velocity detected planets -- have predicted timing effect larger than 1 second. We also compute the theoretical timing precision for the PLATO mission, that will observe a similar stellar population, and find that a 1 second effect would be frequently readily observable. We also find that on-sky coplanarity of multiple objects in the same system can be probed more easily than the on-sky position angle of each of the objects separately. Conclusions: We show a new observable from transit photometry becomes available when very high precision transit timing is available. We find that there is a good match between projected capabilities of the future space missions PLATO and CHEOPS and the new observable. We give some initial science question that such a new observable may be related to and help addressing.

description: The charged and magnetic states of isolated impurities dissolved in amorphous metallic alloy are investigated. The Hamiltonian of the system under study is the generalization of Anderson impurity model. Namely, the processes of elastic and non-elastic scattering of conductive electrons on the ions of a metal and on a charged impurity are included. The configuration averaged one-particle Green's functions are obtained within Hartree-Fock approximation. A system of self-consistent equations is given for calculation of an electronic spectrum, the charged and the spin-polarized impurity states. Qualitative analysis of the effect of the metallic host structural disorder on the observed values is performed. Additional shift and broadening of virtual impurity level is caused by a structural disorder of impurity environment.

description: In face-to-face (FtF) communication, facial expressions provide information on the emotional state and personality traits of individuals. These effects are not only seen when interacting directly with another person but also when viewing others interacting with each other. We examined whether emojis play similar roles in text-based exchanges on digital platforms. Participants (N =177) viewed two people exchanging via text. Person A initiated the exchange, and Person B responded in either an agreeable or disagreeable manner. In half of the agreeable exchanges, Person B's messages were accompanied by a positive emoji, and in half of the disagreeable exchanges, Person B's messages were accompanied by a negative emoji. Exchanges were couched in a personal, professional, or romantic context. We measured trait perceptions of agreeableness and perceptions of the emotional state of Person B. Emojis magnified both perceptions of (dis)agreeableness and perceptions of the emotional state of Person B. Social context had no effect, suggesting that the effect of emojis is consistent across social contexts. We conclude that emojis play a similar role in digital communication as facial expressions do in FtF communication, though with some differences.

description: Following a recent suggestion by Weinberg, we use the large-N expansion in QCD to discuss the decay amplitudes of tetraquarks into ordinary mesons as well as their mixing properties. We find that the flavor structure of the tetraquark is a crucial ingredient to determine both this mixing as well as the decays. Although in some cases tetraquarks should be expected to be as narrow as ordinary mesons, they may get to be even narrower, depending on this flavor structure.

description: The demonstration that Nanocrystalline Diamond (NCD) can retain the superior Young's modulus (1,100 GPa) of single crystal diamond twinned with its ability to be grown at low temperatures (<450 °C) has driven a revival into the growth and applications of NCD thin films. However, owing to the competitive growth of crystals the resulting film has a roughness that evolves with film thickness, preventing NCD films from reaching their full potential in devices where a smooth film is required. To reduce this roughness, films have been polished using Chemical Mechanical Polishing (CMP). A Logitech Tribo CMP tool equipped with a polyurethane/polyester polishing cloth and an alkaline colloidal silica polishing fluid has been used to polish NCD films. The resulting films have been characterised with Atomic Force Microscopy, Scanning Electron Microscopy and X-ray Photoelectron Spectroscopy. Root mean square roughness values have been reduced from 18.3 nm to 1.7 nm over 25 μm$^2$, with roughness values as low as 0.42 nm over ~ 0.25 μm$^2$. A polishing mechanism of wet oxidation of the surface, attachment of silica particles and subsequent shearing away of carbon has also been proposed.

description: What does the equilibrium atomic, molecular or spin configuration of a glass phase look like? Is there only one unique equilibrium configuration or are there infinitely many configurations of equal energy? The processes and mechanisms governing the path towards equilibrium, i.e. the dynamics of glassy systems, provide insights to these questions. Here we discuss the intrinsic dynamics of different glassy magnets: of spin-glasses, frustrated ferromagnets, superspin-glasses and other nanostructured systems with competing ferro- and antiferromagnetic interactions and randomness in their spatial distribution. This paper is intended as a brief update on some unsolved problems and the current empirical status in the field of disordered and frustrated magnetism.
