description: This study explored the relationship between social worker well-being and personal involvement in expressive arts. I selected interpretive phenomenology, a qualitative approach, because I wanted to gain in-depth insight into social worker experience within a context of arts engagement. Reflexively using my own deep interest in the arts and previous social work experience, I provide an interpretation of participants’ perceptions, encompassing cognitive, spiritual, psychological and/or physical components. This study illuminates a transformative process that may contribute to more effective practice. Through art, participants were open to encountering the spaces between their experience and the multitude of meanings they might find within the context of their lives, their work, and their art. The lack of existing research regarding social workers’ use of the arts to enhance wellness warrants the focus of this thesis, which adds to the self-care discourse amongst social work researchers, practitioners, students, and educators.

description: We address the energetic stability of the graphene/SiC(0001) interface and the associated binding mechanism by studying a series of low-strain commensurate interface structures within a density functional scheme. Among the structures with negligible strain, the 6\surd3\times6\surd3 R30° SiC periodicity shows the lowest interface energy, providing a rationale for its frequent experimental observation. The interface stability is driven by the enhanced local reactivity of the substrate-bonded graphene atoms undergoing sp2-to-sp3 rehybridization (pyramidalization). By this mechanism, relaxed structures of higher stability exhibit more pronounced graphene corrugations at the atomic scale.

description: A 1-percent increase or decrease in milk prices Increases or decreases U.S. milk production a total of about half of 1 percent over a 4-year period. This study measures the effects of changes in major economic factors of milk production on the amount of milk dairy farmers produce. The major factors include prices farmers receive for milk; input costs of running a dairy farm (measured here by prices of alfalfa hay and corn); profits farmers would receive in alternative farm enterprises (measured by beef prices and, again, feed prices); and general economic conditions (measured by the unemployment rate).
SCET, QCD and Wilson Lines

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Soft Collinear Effective Theory (SCET) is an effective field theory which describes the interactions of low invariant mass jets which are highly boosted with respect to one another. In the standard formulation of SCET, the effective Lagrangian for collinear fields is expanded in inverse powers of the energy. At leading order this leads to manifest decoupling of soft and collinear degrees of freedom; however, subleading terms in the effective Lagrangian violate this manifest decoupling. In this paper we point out that the collinear expansion in the SCET Lagrangian is unnecessary, and that the SCET Lagrangian may instead be written as multiple decoupled copies of QCD. The interactions between the sectors in full QCD are reproduced in the effective theory by an external current consisting of QCD fields coupled to Wilson lines. We illustrate this picture with two examples: dijet production and B->X_s + gamma.

description: The near-field interaction between two neighboring particles is known to produce enhanced radiative heat transfer. We advance in the understanding of this phenomenon by including the full electromagnetic particle response, heat exchange with the environment, and important radiative corrections both in the distance dependence of the fields and in the particle absorption coefficients. We find that crossed terms of electric and magnetic interactions dominate the transfer rate between gold and SiC particles, whereas radiative corrections reduce it by several orders of magnitude even at small separations. Radiation away from the dimer can be strongly suppressed or enhanced at low and high temperatures, respectively. These effects must be taken into account for an accurate description of radiative heat transfer in nanostructured environments.

Subjects: subject: Psychology--Clinical
subject: perinatal stroke
subject: family impact
subject: Caregivers

description: In this dissertation, I examined the parental and familial impact of raising a child with perinatal stroke. This was accomplished through three carefully planned studies that used a population-based perinatal stroke research cohort and survey methodology. In the first study, the APSP Parental Outcome Measure (POM) was developed to assess the psychosocial impact of raising a child with perinatal stroke, including quantifiable measures of guilt and blame. The results provided strong evidence for the POM’s psychometric properties among a sample of parents of children with perinatal stroke. More specifically, evidence was gathered for the POM’s internal consistency, test-retest reliability, concurrent validity, convergent validity, incremental validity, and factor structure. In the second study, the psychosocial impact of raising a child with perinatal stroke was examined. Mothers of children with perinatal stroke were compared with mothers of children with typical development and fathers of children with perinatal stroke on measures of well-being. The results illustrated that the majority of mothers of children with perinatal stroke were indistinguishable from controls. However, mothers of children with moderate and severe conditions had worse outcomes on measures of depression, quality of life, marital satisfaction, and family functioning. Furthermore, mothers of children with perinatal stroke had similar or slightly worse outcomes than fathers with the most pronounced differences in their anxiety symptoms and feelings of guilt. In the third study, predictors of parent and family outcomes were examined, along with mediators and moderators, in order to better understand the process of adaptation to raising a child with perinatal stroke. The results showed that child and psychosocial variables predicted parent and family outcomes. Mores specifically, condition severity, social support, anxiety symptoms, and blame independently predicted caregiver depression, while condition severity, stress levels, and marital quality independently predicted family functioning. An evaluation of mediators and moderators yielded evidence that parental blame mediates the relationship between condition severity and caregiver depression. Collectively, these findings demonstrate that raising a child with perinatal stroke increases parents’ risk for psychosocial morbidity. However, a large portion of parents demonstrate resiliency, and a complex interplay of factors contribute to the condition’s parental and familial impact.

The Music in Garcilaso de la Vega’s Poetry and his Poetry in Music: A Musico-Poetic Interchange Between Sixteenth-Century Spain and Italy
Creators: name: Oss-Cech Chiacchia, Maria Carolina
Publisher: name: Graduate Studies
Year: 2014
Subjects: subject: Literature--Romance
subject: Romance literature
subject: Music
subject: Renaissance poetry

description: This dissertation, about the music of Garcilaso de la Vega’s poetry and his poetry in music, draws from the fields of philology, linguistics, and musicology to provide an interdisciplinary perspective of the topic embedded in two interrelated contexts: Hispanic/Neapolitan Renaissance poetry and music. Garcilaso, a sixteenth-century courtier and soldier, travelled extensively to serve in war especially in Italy. This cross-cultural contact led to the adaptation of Italian poetic forms and meters. Garcilaso fused imitated forms with the lyricism of his Spanish language. Scholars repeatedly praised his poetry for mastery of form and style, and a finest sense of musicality. And thus the question: What do critics mean by musicality? And how does musicality serve the literary medium in the construct of meaning? Few scholars have investigated Garcilaso’s lyric expression. Moreover, considering that humanist imitation of the classics extended to their theories of language as a means to convey their ideology, and given that Renaissance composers sought the finest vernacular poetry for their musical settings, in the second part I pose the question: To what extent did Garcilaso’s poetry and the sixteenth-century musico-poetic context intersect? For the first argument, I construe musicality, in Bakhtinian terms, as the means by which the poetic voice conveys meaning and establishes a dialogue with the listener and other texts. I thus examine the tapestry of poetic linguistic elements that heightens the etymological meaning of words. For the next section, I survey the complex tapestry of Hispanic/Neapolitan dialogic genres to understand how Garcilaso’s poetry intersected with the musico-poetic landscape. My findings reveal that the epithet ‘musical’ in Garcilaso’s poetry, is substantiated by a linguistic soundscape consisting of tangible elements embedded in every fibre of the poetic structures herein analyzed. In the second part of the study, Garcilaso’s poetry emerges in the music collections by Alonso Mudarra, Diego Pisador, Esteban Daza, Pere Alberch Vila, Pedro and Francisco Guerrero, Juan Vásquez, the Italian composer Giulio Severino, and in Italian anonymous manuscripts, such as Magliabechiano XIX (Florence, Italy). This dissertation includes a CD containing Renaissance musical settings of Garcilaso’s poetry, including a new transcription of the Magliabechiano musical setting.

Year: 2023

description: This publication comprises the Software Management Plan (SMP) developed in the HPO-Navi project. The project was funded in the Literature and Information System (LIS) track of the DFG with the aim of increasing the maturity level of scientific software under development, developing improved measures for the quality assurance of this software and for long-term availability. The Ubiquity Generator Framework (UG) software developed in the project provides a software infrastructure to make existing sequential implementations HPC-capable. The UG framework is of interest to developers of specialized optimization algorithms and can be used directly to solve specific problem classes in the field of scientific computing. Due to the naturally high software technology hurdles on HPC systems, UG was initially a highly specialized tool and could only be used to a limited extent without the involvement of the main developer. The central challenge of the project was to create a mechanism for the sustainable development and permanent provision and archiving of the research software. The aim was for UG to achieve the status of a "software product" with implementation of the following project content: - Documentation of the software: a description of the API and the simple connection of further basic solvers, installation instructions for various target platforms and a description of the structure and documentation of the source code as a basis for the distributed sustainable development of UG. - Development of missing user functions of UG: increased platform independence for shared memory parallelization and better logging function for the analysis and verification of results. - Development of a sample data management plan for future research projects that want to use UG and document their research results according to DFG standards for good scientific practice. - Quality assurance: by defining code guidelines, uniform concepts and criteria for the qualitative evaluation of new functions and implementing standards for code review and processes for continuous integration. A complementary goal was to improve the provision, accessibility and long-term reusability of the research software. - Use of an open Git server as a distributed development platform, provision of a download server for releases and sustainable storage of the software code and the associated meta-information. - Improved presentation and visibility through publication in publicly accessible repositories. This includes the prototypical extension of the OPUS 4 repository software widely used in Germany as a means of publishing software with a landing page that can be resolved via a DOI, and improved linking and presentation of UG in swMATH. - Digital long-term archiving: experimental inclusion of software code in an OAIS-compliant digital archiving system and evaluation of the approach in the areas of digital archiving and research data management.

description: The estimated rate of return to investment in new dairy operations is higher in the Southwestern United States than in Minnesota or Washington, assuming 1981 prices and construction and operating costs. This difference comes from lower investment required per cow, more milk produced per cow, and higher milk prices in the Southwest. The report compares the profitability of dairy farming in Minnesota, Arizona, New Mexico, and Washington. Results indicate that the Southwest likely will continue to increase its share of total U.S. milk production.

Additively Manufactured TiTa Alloys for Improved Osseointegration of Bone Implants
Creators: name: ERIN GRACE BRODIE
Publisher: name: Monash University
Year: 2020
Subjects: subject: 90301 Biomaterials
subject: FOS: Medical engineering

description: This thesis explores new and improved metals for bone implants. The main metal used for bone implants today, Ti-6Al-4V, was originally designed for aircraft. New 3D printing technologies allow us to combine metals that were previously extremely difficult to melt together. Hence, we can now design new alloys which not only better mimic the strength and stiffness of bone but can also encourage bone growth around an implant. This research explores the manufacture of such an alloy system, titanium-tantalum, which has the potential to significantly reduce implant loosening and failure.

description: Demand controlled ventilation (DCV) is used to reduce the amount of energy required to condition outdoor air introduced into a building based by monitoring occupancy. This thesis reports the hours DCV is used in an existing building in Calgary. Results showed DCV was used approximately 20% of annual fan operating hours when paired with an air-side economizer and just over 60% when a heat recovery wheel was part of the system. A Simulink model was built to compare the performance of two currently used DCV approaches based on carbon dioxide readings (CO2-DCV). The model showed positioning a sensor in the supply air duct (SACO2-DCV) to serve multiple zones of a re-circulating system maintained lower CO2 levels when occupancy varied between rooms than if the sensor were in the return-air duct (RACO2-DCV). The model showed these lower CO2 levels were due to SACO2-DCV over-ventilating spaces relative to typical requirements.

description: Ensuring communications security in Wireless Sensor Networks (WSNs) indeed is critical; due to the criticality of the resources in the sensor nodes as well as due to their ubiquitous and pervasive deployment, with varying attributes and degrees of security required. The proliferation of the next generation sensor nodes, has not solved this problem, because of the greater emphasis on low-cost deployment. In addition, the WSNs use data-centric multi-hop communication that in turn, necessitates the security support to be devised at the link layer (increasing the cost of security related operations), instead of being at the application layer, as in general networks. Therefore, an energy-efficient link layer security framework is necessitated. There do exists a number of link layer security architectures that offer some combinations of the security attributes desired by different WSN applications. However, as we show in this paper, none of them is responsive to the actual security demands of the applications. Therefore, we believe that there is a need for investigating the feasibility of a configurable software-based link layer security architecture wherein an application can be compiled flexibly, with respect to its actual security demands. In this paper, we analyze, propose and experiment with the basic design of such configurable link layer security architecture for WSNs. We also experimentally evaluate various aspects related to our scheme viz. configurable block ciphers, configurable block cipher modes of operations, configurable MAC sizes and configurable replay protection. The architecture proposed is aimed to offer the optimal level of security at the minimal overhead, thus saving the precious resources in the WSNs.

Exact relation for correlation functions in compressible isothermal turbulence

description: Compressible isothermal turbulence is analyzed under the assumption of homogeneity and in the asymptotic limit of a high Reynolds number. An exact relation is derived for some two-point correlation functions which reveals a fundamental difference with the incompressible case. The main difference resides in the presence of a new type of term which acts on the inertial range similarly as a source or a sink for the mean energy transfer rate. When isotropy is assumed, compressible turbulence may be described by the relation, $- {2 \over 3} ε_{\rm{eff}} r = {\cal F}_r(r)$, where ${\cal F}_r$ is the radial component of the two-point correlation functions and $ε_{\rm{eff}}$ is an effective mean total energy injection rate. By dimensional arguments we predict that a spectrum in $k^{-5/3}$ may still be preserved at small scales if the density-weighted fluid velocity, $ρ^{1/3} \uu$, is used.

Natural selection. II. Developmental variability and evolutionary rate
Creators: name: Frank, Steven A.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Populations and Evolution (q-bio.PE)
subject: FOS: Biological sciences

description: In classical evolutionary theory, genetic variation provides the source of heritable phenotypic variation on which natural selection acts. Against this classical view, several theories have emphasized that developmental variability and learning enhance nonheritable phenotypic variation, which in turn can accelerate evolutionary response. In this paper, I show how developmental variability alters evolutionary dynamics by smoothing the landscape that relates genotype to fitness. In a fitness landscape with multiple peaks and valleys, developmental variability can smooth the landscape to provide a directly increasing path of fitness to the highest peak. Developmental variability also allows initial survival of a genotype in response to novel or extreme environmental challenge, providing an opportunity for subsequent adaptation. This initial survival advantage arises from the way in which developmental variability smooths and broadens the fitness landscape. Ultimately, the synergism between developmental processes and genetic variation sets evolutionary rate.

description: A unified approach to modeling flows of slightly compressible fluids through naturally fractured media using transient interporosity models is presented. The unified fractional differential transient interporosity flow model is derived using the methodology of asymptotic analysis for problems with small parameters arising based on the assumption about much lower permeability of matrix blocks compared to fractures. The model is established for any shape of matrix blocks and unifies existing transient interporosity flow models formulated for matrix spheres, cylinders and slabs. It is formulated in the form of a fractional order partial differential equation with the Caputo derivative of order 1/2 with respect to time. Explicit solutions for the unified model are derived for different axisymmetrical domains using Hankel-Weber transforms. The surface area-to-volume ratio is shown to be the fundamental parameter in the flow description. The rescaling technique that involves this parameter allows observing similarities of flow for any matrix geometries.

Shock Wave Acceleration in a High-Aspect-Ratio Shock Tube

description: A shock tube model was developed to predict diaphragm opening time, shock acceleration, and shock formation in a rectangular channel. Heat transfer and friction effects at the tube walls on shock acceleration were analyzed. The model was compared to shock tube experiments using slit-type (fast opening time) and petal-type (slow opening time) diaphragms. Helium and air were used as fluid media in the high-pressure and low-pressure sections of the rectangular shock tube, respectively. Due to the high-aspect-ratio of the rectangular shock tube cross-section, a methodology was developed to produce petal diaphragms resulting in consistent bursting pressure, petaling without fragment release and symmetric opening resulting in a symmetric shock wave. Schlieren imaging was also used to investigate the shock wave structure development.

description: Given an elliptic curve E over a finite field F_q of q elements, we say that an odd prime ell not dividing q is an Elkies prime for E if t_E^2 - 4q is a square modulo ell, where t_E = q+1 - #E(F_q) and #E(F_q) is the number of F_q-rational points on E; otherwise ell is called an Atkin prime. We show that there are asymptotically the same number of Atkin and Elkies primes ell < L on average over all curves E over F_q, provided that L >= (log q)^e for any fixed e > 0 and a sufficiently large q. We use this result to design and analyse a fast algorithm to generate random elliptic curves with #E(F_p) prime, where p varies uniformly over primes in a given interval [x,2x].

Archives And Copyright: Risk And Reform

Publisher: name: Zenodo
Year: 2013

description: This paper considers the place of the archive sector within the copyright regime, and how copyright impacts upon the preservation, access to, and use of archival holdings. It will begin with a critical assessment of the current parameters of the UK copyright regime as it applies to the work of archivists, including recommendations for reform that have followed in the wake of the Gowers Review of Intellectual Property (2006-2010), the Hargreaves Review of Intellectual Property and Growth (2010-2011), the recent Consultation on Copyright (2011-12), as well as the government’s response thereto: Modernising Copyright (2012). It considers the various problems the copyright regime presents for archives undertaking mass digitisation projects as well as recent European and UK initiatives in this domain. It argues that the UK copyright regime, even when read in conjunction with current national and regional recommendations for reform, falls short of delivering a legal framework that would enable archivists to realise the full potential that comprehensive, universal online access to the country’s archival holdings would contribute to local and national democracy and accountability, to education, learning, and culture, and to the sense of identity and place for local people, communities and organisations. Ultimately, a case is made for the differential treatment of archives within the copyright regime – different, that is, from libraries and other related institutions operating within the cultural sector. The paper concludes with a policy recommendation that would greatly enhance the ability of archives to provide online access to their holdings, while at the same time safeguarding the economic interests of the authors and owners of copyright-protected work.

Their patches admit rational bilinear quaternionic Bézier parametrizations and are used in geometric design and architecture. Dupin cyclidic cubes are a natural trivariate generalization of Dupin cyclide patches. In this article, we derive explicit formulas for control points and weights of rational trilinear quaternionic Bézier parametrizations of Dupin cyclidic cubes and relate them with the classical construction of the Miquel point.

description: Data from USDA's Resource Economics Survey challenge the common, but not well-substantiated, view that farmers are less concerned with erosion on land they rent than on land they own. At the national level, farmers' conservation efforts—as reflected in crop rotation, tillage practices, and use of conservation practices—on rented cropland compare favorably with those on owner-operated cropland. Nevertheless, rented land is subject to more erosion because a greater proportion of it is used to produce erosive row crops.

description: This is the third in a sequence of three reports on Parody & Pastiche, commissioned to evaluate policy options in the implementation of the Hargreaves Review of Intellectual Property & Growth (2011). Study I presents new empirical data about music video parodies on the online platform YouTube; Study II offers a comparative legal review of the law of parody in seven jurisdictions; Study III provides a summary of the findings of Studies I & II, and analyses their relevance for copyright policy.

Links to all three studies are available from

http://www.ipo.gov.uk/pro-ipresearch/ipresearch-year/ipresearch-year-2013.htm

Study III is structured as follows:

First, we discuss the empirical findings from Study I. A sample of 8,299 user-generated music video parodies was constructed relating to the top-100 charting music singles in the UK for the year 2011. The key findings are:

	Parody is a signifi cant consumer activity: On average, there are 24 user-generated parodies available for each original video of a charting single.
	There is no evidence for economic damage to rights holders through substitution: The presence of parody content is correlated with, and predicts larger audiences for original music videos.
	The potential for reputational harm in the observed sample is limited: Only 1.5% of all parodies sampled took a directly negative stance, discouraging viewers from commercially supporting the original.
	Observed creative contributions were considerable: In 78% of all cases, the parodist appeared on camera (also diminishing the possibility of confusion).
	There exists a small but growing market for skilled user-generated parody: Parodists who exhibit higher production values in their works attract larger audiences, which can be monetized via revenue share with YouTube.

Secondly, we present a distilled discussion of the legal treatment of parodies in seven jurisdictions that have implemented a copyright exception for parody (Australia, Canada, France, Germany, Netherlands, UK, and USA). The underlying principles (including economic and constitutional) governing divergent legal approaches are identified, and a list of policy options is presented.

Thirdly, we provide a synthesis of the legal analysis and the empirical data. Each of the policy options identified in Study II is examined for its likely impact on the empirical sample gathered in Study I. Finally, some recommendations are made.
Enthalpy-based Thermal Evolution of Loops: II. Improvements to the Model

description: This paper develops the zero-dimensional (0D) hydrodynamic coronal loop model "Enthalpy-based Thermal Evolution of Loops" (EBTEL) proposed by Klimchuk et al (2008), which studies the plasma response to evolving coronal heating, especially impulsive heating events. The basis of EBTEL is the modelling of mass exchange between the corona and transition region and chromosphere in response to heating variations, with the key parameter being the ratio of transition region to coronal radiation. We develop new models for this parameter that now include gravitational stratification and a physically motivated approach to radiative cooling. A number of examples are presented, including nanoflares in short and long loops, and a small flare. The new features in EBTEL are important for accurate tracking of, in particular, the density. The 0D results are compared to a 1D hydro code (Hydrad) with generally good agreement. EBTEL is suitable for general use as a tool for (a) quick-look results of loop evolution in response to a given heating function, (b) extensive parameter surveys and (c) situations where the modelling of hundreds or thousands of elemental loops is needed. A single run takes a few seconds on a contemporary laptop.

description: Gas-phase complex organic molecules are commonly detected toward high-mass protostellar hot cores. Detections toward low-mass protostars and outflows are comparatively rare, and a larger sample is key to investigate how the chemistry responds to its environment. Guided by the prediction that complex organic molecules form in CH3OH-rich ices and thermally or non-thermally evaporate with CH3OH, we have identified three sight-lines in the Serpens core - SMM1, SMM4 and SMM4-W - which are likely to be rich in complex organics. Using the IRAM 30m telescope, narrow lines (FWHM of 1-2 km s-1) of CH3CHO and CH3OCH3 are detected toward all sources, HCOOCH3 toward SMM1 and SMM4-W, and C2H5OH not at all. Beam-averaged abundances of individual complex organics range between 0.6 and 10% with respect to CH3OH when the CH3OH rotational temperature is applied. The summed complex organic abundances also vary by an order of magnitude, with the richest chemistry toward the most luminous protostar SMM1. The range of abundances compare well with other beam-averaged observations of low-mass sources. Complex organic abundances are of the same order of magnitude toward low-mass protostars and high-mass hot cores, but HCOOCH3 is relatively more important toward low-mass protostars. This is consistent with a sequential ice photochemistry, dominated by CHO-containing products at low temperatures and early times.

Twitter (R)Evolution: Privacy, Free Speech And Disclosure

description: Abstract

Using Twitter as a case study, this paper sets forth the legal tensions faced by social networks that seek to defend privacy interests of users. Recent EC and UN initiatives have begun to suggest an increased role for corporations as protectors of human rights. But, as yet, binding rather than voluntary obligations of this kind under international human rights law seem either non-existent or highly conflicted, and structural limitations to such a shift may currently exist under both US and UK law. Companies do not face decisions regarding disclosure in a vacuum, rather they face them constrained by existing obligations under (sometimes conflicting) legal demands. Yet, companies such as Twitter are well-positioned to be advocates for consumers’ interests in these legal debates. Using several recent corporate disclosure decisions regarding user identity as illustration, this paper places questions of privacy, free speech and disclosure in broader legal context. More scholarship is needed on the mechanics of how online intermediaries, especially social media, manage their position as crucial speech platforms in democratic as well as less democratic regimes.

Spin relaxation in CdTe quantum dots with a single Mn atom

description: We have investigated spin relaxation times in CdTe quantum dots doped with a single Mn atom, a prototype of a system where the interaction between a single charge carrier and a single spin takes place. A theoretical model that was used includes the electron-Mn spin exchange interaction responsible for mixing of the states of different spin in the basic Hamiltonian and electron-phonon interaction as a perturbation responsible for transitions between the states. It was found that the dominant electron-phonon interaction mechanism responsible for spin relaxation is the interaction with acoustic phonons through deformation potential. Electron and Mn spin relaxation times at room temperature take values in the range from microseconds at a magnetic field of 0.5 T down to nanoseconds at a magnetic field of 10 T and become three orders of magnitude larger at cryogenic temperatures. It was found that electron spin-orbit interaction has a negligible effect on spin relaxation times, while the changes in the position of the Mn atom within the dot and in the dot dimensions can change the spin relaxation times by up to one order of magnitude.

description: The tight-binding model of electrons in graphene is reviewed. We derive low-energy Hamiltonians supporting massless Dirac-like chiral fermions and massive chiral fermions in monolayer and bilayer graphene, respectively, and we describe how their chirality is manifest in the sequencing of plateaus observed in the integer quantum Hall effect. The opening of a tuneable band gap in bilayer graphene in response to a transverse electric field is described, and we explain how Hartree theory may be used to develop a simple analytical model of screening.
