Embeddings for General Relativity

description: We present a systematic approach to embed $n$-dimensional vacuum general relativity in an $(n + 1)$-dimensional pseudo-Riemannian spacetime whose source is either a (non)zero cosmological constant or a scalar field minimally-coupled to Einstein gravity. Our approach allows us to generalize a number of results discussed in the literature. We construct {\it all} the possible (physically distinct) embeddings in Einstein spaces, including the Ricci-flat ones widely discussed in the literature. We examine in detail their generalization, which - in the framework under consideration - are higher-dimensional spacetimes sourced by a scalar field with flat (constant $\neq 0$) potential. We use the Kretschmann curvature scalar to show that many embedding spaces have a physical singularity at some finite value of the extra coordinate. We develop several classes of embeddings that are free of singularities, have distinct non-vanishing self-interacting potentials and are continuously connected (in various limits) to Einstein embeddings. We point out that the induced metric possesses scaling symmetry and, as a consequence, the effective physical parameters (e.g., mass, angular momentum, cosmological constant) can be interpreted as functions of the extra coordinate.

description: Sponges are common and diverse in California, but they have received little study in the region, and the identities of many common species remain unclear. Here we combine fresh collections and museum vouchers to revise the order axinellida for California. Seven new species are described: Endectyon (Endectyon) hispitumulus, Eurypon curvoclavus, Aulospongus viridans, Aulospongus lajollaensis, Halicnemia litorea, Halicnemia montereyensis, and Halicnemia weltoni. One new combination is also described, and two existing species are reduced to junior synonyms, resulting in a total of 13 species; a dichotomous key to differentiate them is provided. DNA data from 9 of the 13 species are combined with publicly available data to produce updated global phylogenies for the order.

description: Motivated by the studies done on magnetically induced superconduc- tivity on QCD vaccum we propose that de Sitter spacetime is a natural superconductor. This is due to the occurrence of spinor condensation. We provide a framework for joining the curvature of spacetime with super- conductor processes. We demonstrate that for a critical value of de Sitter radius unstable tachyon modes exist showing the existence of a supercon- ducting phase

description: La thérapie antirétrovirale a révolutionné le traitement des personnes vivant avec le VIH (PVVIH) leur permettant de jouir d’une espérance de vie normale. Cependant, celle-ci engendre une panoplie d’effets secondaires physiques, psychologiques et sociaux chez les PVVIH qui sont non négligeables, puisqu’ils affectent considérablement la qualité de vie de ces dernières. De nombreux chercheurs ont démontré qu’il existe un lien entre la relation patient-médecin et l’adhérence aux antirétroviraux. Conscient de l’importance de cette relation, cette étude qualitative explore la relation patient-médecin et plus précisément, son rôle dans l’expérience des effets secondaires chez les PVVIH, rôle qui à ce jour, n’a pas été étudié en profondeur. Un devis de recherche qualitatif, de type descriptif, convenait aux objectifs de cette étude, puisqu’il permet d’explorer de manière détaillée le vécue des PVVIH et de décrire leur expérience avec le médecin. Au plan méthodologique, la théorisation ancrée était tout à fait appropriée pour répondre à la problématique de recherche. La collecte des données s’est déroulée durant la période estivale de 2014, par le biais d’entrevues, auprès de 50 PVVIH aux prises avec des effets secondaires. En résumé, les résultats de cette étude montrent que la relation patient-médecin s’inscrit dans un modèle de soins prédominant en VIH/SIDA dans lequel l’accès est limité, le médecin détient le monopole dans la prescription et la prise en charge des PVVIH et où la charge virale est trop souvent le seul indicateur de la santé de ces dernières. L’analyse des données a permis de mettre en lumière les différents processus utilisés par les médecins pour s’assurer de maintenir leur autorité (pouvoir) sur les PVVIH, ainsi que les mécanismes de résistance de ces dernières. On constate que les PVVIH mettent en place des stratégies pour prendre en charge leur santé. Malheureusement, une relation patient-médecin problématique engendre son lot d’impacts négatifs chez les PVVIH (isolement, abandon et souffrance) qui entravent à la prise en charge des effets secondaires.

description: Chen Zhi's National Taihu Lake Park published in 1929, is the first planning of our country’s national park. This article attempts to analyze the beautification and recreation of Chen Zhi's conception. The author starts with the development of the national park at that time and the practice experience of Chen Zhi, combing the Taihu Lake watershed’s natural and social conditions. What’s more, the author interprets the planning text of Taihu Lake from four aspects, including landscape resources, traffic system, supporting facilities, and construction of scenic forests. Based on this, this article analyzes Chen Zhi’s considerations of drawing lessons from abroad and integrating them into the local culture, pursues the relevance of its design concept with America and Japan, and presents the spread of national park’s concept in our country in the same period.

description: Through an NEH-funded initiative, Cornell University Library is creating a technical, curatorial, and managerial framework for preserving access to complex born-digital new media objects. The Library's Rose Goldsen Archive of New Media Art provides the testbed for this project. This collection of complex interactive born-digital artworks are used by students, faculty, and artists from various disciplines. Interactive digital assets are far more complex to preserve and manage than single uniform digital media files. The preservation model developed will apply not merely to new media artworks, but to other rich digital media environments. This article describes the project's findings and discoveries, focusing on a user survey conducted with the aim of creating user profiles and use cases for born-digital assets like those in the testbed collection. The project's ultimate goal is to create a preservation and access practice grounded in thorough and practical understanding of the characteristics of digital objects and their access requirements, seen from the perspectives of collection curators and users alike. We discuss how the survey findings informed the development of an artist questionnaire to support creation of user-centric and cost-efficient preservation strategies. Although this project focuses on new media art, our methodologies and findings will inform other kinds of complex born-digital collections.

description: Listening to students’ mathematical reasoning is commonly highlighted as one of the main features of progressive mathematics teaching, yet, little is known about how teachers enact listening in the classroom. This project explores the experiences of teachers who value a listening orientation in their teaching practice. My research question is: How do teachers who profess to have a listening orientation experience listening and responding to student mathematical thinking? I will draw from enactivism (Varela, Thompson, & Rosch, 1991) as a theoretical framework to understand the world of significance brought forth by teachers. A phenomenological approach will ground this project on participants’ experiences. I conducted interviews with five elementary school teachers from grades three to eight. In my data analysis I have identified stories and observations which reveal teachers’ patterns of interaction with students and the type of relationships established with the students. The findings suggest similarities and uniqueness among the world brought forth by the teachers interviewed. The relevance of establishing relationships and encouraging students to express their mathematical reasoning seems to be central to maintaining a listening environment in teaching.

description: The port city and British colony of Hong Kong had from its inception been characterized by a capitalist ethic and by dense settlement on land hemmed in between hills and sea. Preserving public land for general recreation was rarely prioritized as a primary government goal. Yet in Hong Kong’s first century (the 1840s to the 1940s) several public parks came into being and were resilient, while others were compromised. The history of these parks reveals no overall scheme, but responses to contingencies, each shaped by moments when public interest necessitated preserving open spaces and fostering green spaces for recreation.

description: The purpose of this study was to determine the organizational cultural profile of Learfield Sports and, to see if there were any statistically significant relationships between expressed organizational cultural type and gender of the respondents and expressed cultural type and the athletic department’s longevity with the sport-marketing property. This study involved 71 general managers and account executives of the outsourced sports marketing firms associated with Learfield Sports. Participants were surveyed via Survey Monkey using the Organizational Culture Assessment Inventory (OCAI). The instrument was researched and developed by Kim S. Cameron and Robert E. Quinn to diagnose an organization's culture using six different cultural dimensions. The statistical package SPSS was used to develop descriptive statistics and frequencies to describe the main characteristics of the sample and to develop organizational-culture profiles. Developed statistics were interpreted using the OCAI to produce an overall organizational culture profile that assesses the six CVF dimensions. After categorization, and in order to answer the posed research questions, a series of chisquare analyses were conducted in order to determine if there was a significant relationship (α .05) between expressed culture type and general managers’ gender, as well as the outsourced marketing firms’ longevity with the associated university. There were no significant findings.
The four"I"s as key concepts in a re-examination of "Machizukuri" as an intrinsically vital element in urban planning for the post-urbanization period
Creators: name: Kobayashi, Keiichi
Publisher: name: International Planning History Society Proceedings
Year: 2018

description: This paper discusses the word “machizukuri” and the versatility of its meaning through examining the interplay between “machizukuri” and statutory urban planning over the past sixty years. By tracing the history of the Japanese urban planning system, it can be seen that one role of “machizukuri” has been to compensate for areas of incompleteness in urban planning. As there has also been an institutionalisation process from “machizukuri” to statutory urban planning, the primary role of “machizukuri” has been to provide a constructive arena for collaboration on efforts to improve regional conditions. As “vitalization” has become the definitive issue for urban planning in the post urbanization period, the four “I”s, incrementalism, intentionality, innovative value creation and integrality of regional development, have been abstracted as necessary conditions for a revised and more readily applicable version of “machizukuri.”

description: It is a fact that Indonesian students have difficulty learning Arabic because of the characteristics and linguistics of different Arabic and Indonesian languages, and their lack of understanding of the similarities between the two languages. The researcher sees that it is necessary to examine the similarities and differences in verbs between the two languages, and then present the way the verb teaches them to give the teacher and learner the desired result. Researchers approached an analytical descriptive approach in the achievement of this study, using comparative analysis methods, to compare between transitive verbs in Arabic and Indonesian and then the researchers divide into two categories, the first category is the equation of transitive verbs in Arabic and Indonesian, the second category is the difference between transitive verbs in Arabic and Indonesian. The study found that the difficulties experienced by Indonesian students began with the following reasons: differences in sentence composition and differences in grammatical and morphological rules.

In our previous work, we introduced the bound state operators and constructed candidate operators for observables in wedges. Under some additional assumptions on the S-matrix, we show that, in order to obtain their strong commutativity, it is enough to prove the essential self-adjointness of the sum of the left and right bound state operators. This essential self-adjointness is shown up to the two-particle component.

description: This paper explores human observer preferences for various sky-like interior lighting scenarios realized by a combination of a blue-enriched indirect uplight component with a correlated color temperature (CCT) of 6,500 K up to 30,000 K and a 4,000 K or 5,500 K direct downlight component. Variations in the natural sky were mimicked by the indirect uplight component reflected from the ceiling of the experimental room. The settings for the direct lighting component, on the other hand, were selected based on the reported outcomes of previous preference studies in the field of interior lighting. The resulting lighting conditions were evaluated by a total of 29 observers, from which subjective ratings of brightness, sky-likeness, satisfaction, pleasantness, and general appeal were collected in an office workplace environment. In this experimental setting, the most preferred lighting conditions exhibited a direct-to-indirect lighting ratio of 50:50 with a CCT of 4,000 K in the direct component and 6,500, 7,500, and 9,000 K in the indirect component. For all examined combinations, none was rated as truly sky-like. Nonetheless, the study results showed that only the combination of a warmer CCT in the direct component and a cooler, blue-enriched CCT in the indirect lighting component leads to a maximum in the subjects’ preference ratings. In summary, the subjects preferred light settings with a white appearance on the work surface without any intense or noticeable blue cast or tint.
Freeing themselves: Puritanism, slavery, and black abolitionists in Massachusetts, 1641-1788
Creators: name: Cameron, Christopher Alain
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: While the available scholarship on the northern antislavery movement focuses primarily on abolitionist committees composed of whites, this thesis argues that in Massachusetts African Americans played a central role in the abolition of slavery and the slave trade in the state. In the early colonial period Puritan religious ideology and the ministers who espoused it influenced the establishment of an institution of slavery that contained the seeds of its own demise. During the 1770s and 1780s Massachusetts blacks availed themselves of their right to petition and bring suits in court, in addition to building organizations, producing literature, and writing essays aimed at undermining proslavery ideology. They effectively harnessed the discourse of Christianity to build a community and influence white abolitionists' antislavery arguments, assisting in the struggle to free themselves and other blacks from the shackles of slavery.

description: The Great East Japan Earthquake was a scale of an earthquake that modern Japan had never experienced before. As a result of this disaster, prolonged evacuation orders were issued to wide areas, and even six years after the earthquake, there are people who still live in temporary houses because they cannot go back to the place where they used to live. This paper focuses on Katsurao Village, Fukushima Prefecture and aims to grasp how the dwellings and family structures changed since the Great East Japan Earthquake as well as the reason for these changes. Intensions as to the future location of their dwellings differ by the age of the members of the household or the areas under the evacuation orders. Young generations do not depend on the existing community, and they wish either to go back to their own old village or move to a more convenient place. It was clarified that many residents want to have a privately-owned house but that there is a small number of people who want to move to a convenient area and choose other types of dwelling.

description: The Einstein Equivalence Principle (EEP) can be probed with astrophysical sources emitting simultaneously different types of neutral particles, or particles with varying energies, by testing their time of flight through the same gravitational field. Here we use the time delays between correlated photons from cosmological transients to constrain the accuracy of the EEP. We take data from two gamma-ray bursts as an example, and use, as a lower limit to the theoretical time delays between different energies, delays arising from only the gravitational field of our own galaxy. We then show that the parameterized post-Newtonian parameter $γ$ is the same for photons over energy ranges between eV and MeV and between MeV and GeV to a part in $10^{-7}$, which is at least one order of magnitude better than previous limits. Combining this bound on the wavelength dependence of $γ$ with the absolute bound $|γ-1|<0.3\%$ from light-deflection measurements at optical (eV) wavelengths, we thus extend this absolute bound on $γ$ to GeV energies.

description: A new way to train a virtual assistant with unsupervised learning is presented in this thesis. Rather than integrating with a particular set of programs and interfaces, this new approach involves shallow integration between the virtual assistant and computer through machine vision. In effect the assistant interprets the computer screen in order to produce helpful recommendations to assist the computer user. In developing this new approach, called AVRA, the following methods are described: an unsupervised learning algorithm which enables the system to watch and learn from user behavior, a method for fast filtering of the text displayed on the computer screen, a deep learning classifier used to recognize key onscreen text in the presence of OCR translation errors, and a recommendation filtering algorithm to triage the many possible action recommendations. AVRA is compared to a similar commercial state-of-the-art system, to highlight how this work adds to the state of the art. AVRA is a deep learning image processing and recommender system that can col- laborate with the computer user to accomplish various tasks. This document presents a comprehensive overview of the development and possible applications of this novel vir- tual assistant technology. It detects onscreen tasks based upon the context it perceives by analyzing successive computer screen images with neural networks. AVRA is a rec- ommender system, as it assists the user by producing action recommendations regarding onscreen tasks. In order to simplify the interaction between the user and AVRA, the system was designed to only produce action recommendations that can be accepted with a single mouse click. These action recommendations are produced without integration into each individual application executing on the computer. Furthermore, the action recommendations are personalized to the user’s interests utilizing a history of the user’s interaction.
Sense of dwelling in disaster relocation

description: This study examines people's displacement in Kesennuma and Rikuzentakata cities in Japan during the last 6 years from the earthquake in 2011 in order to inquire the factors of the sense of dwelling in disaster relocation. By examining how the relocations of houses impact on people’s identity, what kind of social issues arose in the process, and how designing houses integrated with their community planning is essential to create a sense of belongings, it aims to explain how the idea of disaster relocation and social housing system should be reframed to adjust to the contemporary social issues. By comparing cases, I will explain how people keep striving to maintain their normal lifestyle, and how it is essential to create smooth integration between private and public space, and to help their own subjective engagement in the reconstruction of community in each stage of their relocations. In the era of displacement due to disasters, we need to reconsider the idea of house as the locus for people's identity and to reframe the idea of social housing and urban planning comprehensively and in process-oriented manner.

A study of unorthodox town making by Akira Tamura

Publisher: name: International Planning History Society Proceedings
Year: 2018

description: This thesis intends to assess how Akira Tamura’s “Town making” vision has been passed down to and utilised by younger generations, focusing on the experiences of a study group in which Tamura’s successors have utilised his vision. Tamura promoted the group as an informal place to convey and understand the essence of town making, and insisted on the importance of flexibility in consideration of stakeholders. This thesis sets out to answer the following questions: (1) what are the key features of Akira Tamura’s town making that have been passed on, and (2) how can they be applied by town planners now and in the future? In preparation for writing this thesis, I conducted semi-structured interviews of 4 former Yokohama public officials and referred to documents in the “Akira Tamura archives” of Yokohama city’s historical library. This case study demonstrates that Tamura aimed not only to improve the law and revise the planning system itself, but to imbue urban planning with greater fluidly.

description: Recent results suggest that a crucial crossroad for quantum gravity is the characterization of the effective dimension of spacetime at short distances, where quantum properties of spacetime become significant. This is relevant in particular for various scenarios of "dynamical dimensional reduction" which have been discussed in the literature. We are here concerned with the fact that the related research effort has been based mostly on analyses of the "spectral dimension", which involves an unphysical Euclideanization of spacetime and is highly sensitive to the off-shell properties of a theory. As here shown, different formulations of the same physical theory can have wildly different spectral dimension. We propose that dynamical dimensional reduction should be described in terms of the "thermal dimension" which we here introduce, a notion that only depends on the physical content of the theory. We analyze a few models with dynamical reduction both of the spectral dimension and of our thermal dimension, finding in particular some cases where thermal and spectral dimension agree, but also some cases where the spectral dimension has puzzling properties while the thermal dimension gives a different and meaningful picture.
description: This V2, while not changing the main results, improves V1 in several ways, including a more in depth analysis of the model in which the thermal dimension only runs at intermediate scales and additional material on the differences between active and passive diffeomorphisms on momentum space

description: Compounding of natural language units is a very common phenomena. In this paper, we show, for the first time, that Twitter hashtags which, could be considered as correlates of such linguistic units, undergo compounding. We identify reasons for this compounding and propose a prediction model that can identify with 77.07% accuracy if a pair of hashtags compounding in the near future (i.e., 2 months after compounding) shall become popular. At longer times T = 6, 10 months the accuracies are 77.52% and 79.13% respectively. This technique has strong implications to trending hashtag recommendation since newly formed hashtag compounds can be recommended early, even before the compounding has taken place. Further, humans can predict compounds with an overall accuracy of only 48.7% (treated as baseline). Notably, while humans can discriminate the relatively easier cases, the automatic framework is successful in classifying the relatively harder cases.

The status and use of soft law in local governments’ management of urban development
Creators: name: Asakawa, Kenji
Publisher: name: International Planning History Society Proceedings
Year: 2018

description: This research aims to analyse the use of administrative guidance such as the local development exaction system for collecting impact fees from developers in connection with housing developments from the viewpoint of “soft law”, as a collection of nonbinding social norms in Japan. It takes a brief look at the history of Japanese administrative guidance on impact fees from 1960s to 1990s, to identify how it contributed to public infrastructure development as a form of soft law in Yokohama. Furthermore, it considers the situation now faced by rapidly growing cities in developing countries and what they may learn facing a similar dilemma to that which confronted Japanese local governments in the past. Finally, it recommends more effective soft law for the management of urban development by cities in developing countries, and identifies challenges, some of which Yokohama experienced and others which it did not, which are likely to arise in developing countries wishing to make use of soft law such as local development exaction systems.

description: The equations of fluctuating nonlinear hydrodynamics for a two component mixture are obtained with a proper choice of slow variables which correspond to the conservation laws in the system. Using these nonlinear equations we construct the basic equations of the mode coupling theory (MCT) and consequent ergodic-nonergodic (ENE) transition in a binary mixture. The model is also analyzed in the one component limit of the mixture to study the dynamics of a tagged particle in the sea of identical particles. According to the existing MCT, dynamics of the single particle correlation is slaved to that of the collective density fluctuations and hence both correlations freeze simultaneously at the ENE transition. We show here from a non-perturbative approach that at the ENE transition, characterized by the freezing of the long time limit of the dynamic correlation of collective density fluctuations to a nonzero value, the tagged particle correlation still decays to zero. Our result implies that the point at which simulation or experimental data of self diffusion constant extrapolate to zero would not correspond to the ENE transition of simple MCT.

The adoption and abolition of the local developmentexaction system by the city of Yokohama
Creators: name: Taguchi, Toshio
Publisher: name: International Planning History Society Proceedings
Year: 2018

description: This thesis intends to explore the rationale behind the adoption and abolition of Yokohama’s local development exaction system (“LDE system”). LDE systems were independently and locally formulated by local governments in response to challenges they faced across Japan, and Yokohama provides a leading example of a functional LDE system pursuant to which land developers were required to donate land for public use as a condition of their receiving development approval from the city government. Ichio Asukata, the socialist mayor at the time of the LDE system’s introduction, invited Akira Tamura, a planner, to the city administration to solve the town planning issues. Japan’s new Town Planning Act of 1968 did not contain provisions authorising the exaction of land. Therefore, Yokohama became the first large city to adopt an LDE system in 1968. The LDE system was used as an administrative guideline which ran the risk of legal challenge by affected developers. After Asukata’s term in office, a succession of conservative mayors narrowed and reduced the obligations imposed under the LDE system and finally ended its use in 2004. This study presents some idea of how local initiatives can be implemented independently by local governments in a highly constrained fiscal environment without any support from the central government.

description: Quantifying synergy among stochastic variables is an important open problem in information theory. Information synergy occurs when multiple sources together predict an outcome variable better than the sum of single-source predictions. It is an essential phenomenon in biology such as in neuronal networks and cellular regulatory processes, where different information flows integrate to produce a single response, but also in social cooperation processes as well as in statistical inference tasks in machine learning. Here we propose a metric of synergistic entropy and synergistic information from first principles. The proposed measure relies on so-called synergistic random variables (SRVs) which are constructed to have zero mutual information about individual source variables but non-zero mutual information about the complete set of source variables. We prove several basic and desired properties of our measure, including bounds and additivity properties. In addition, we prove several important consequences of our measure, including the fact that different types of synergistic information may co-exist between the same sets of variables. A numerical implementation is provided, which we use to demonstrate that synergy is associated with resilience to noise. Our measure may be a marked step forward in the study of multivariate information theory and its numerous applications.
Observation of long range magnetic ordering in pyrohafnate Nd2Hf2O7: A neutron diffraction study

description: We have investigated the physical properties of a pyrochlore hafnate Nd2Hf2O7 using ac magnetic susceptibility χ_ac(T), dc magnetic susceptibility χ(T), isothermal magnetization M(H) and heat capacity C_p(T) measurements, and determined the magnetic ground state by neutron powder diffraction study. An upturn is observed below 6 K in C_p(T)/T, however both C_p(T) and χ(T) do not show any clear anomaly down to 2 K. The χ_ac(T) shows a well pronounced anomaly indicating an antiferromagnetic transition at T_N = 0.55 K. The long range antiferromagnetic ordering is confirmed by neutron diffraction. The refinement of neutron diffraction pattern reveals an all-in/all-out antiferromagnetic structure, where for successive tetrahedra, the four Nd3+ magnetic moments point alternatively all-into or all-out-of the tetrahedron, with an ordering wavevector k = (0, 0, 0) and an ordered state magnetic moment of m = 0.62(1) μ_B/Nd at 0.1 K. The ordered moment is strongly reduced reflecting strong quantum fluctuations in ordered state.

Profile of Akira Tamura

Publisher: name: International Planning History Society Proceedings
Year: 2018

description: This essay is a profile of Akira Tamura (1926-2010), and an attempt to locate him in the contemporary history of city planning in Japan. In the 1960s Yokohama faced various urban problems accompanying its rapid economic growth. Ichio Asukata, elected in 1963 as the new socialist mayor, tried to solve them through the local government in an era when the central government’s power remained strong. Asukata then met Tamura, who was working for a local planning office, and asked for his assistance. Tamura proposed to Asukata a new concept for Yokohama as Japan’s ‘international management centre’, and the implementation of the Six Spine Projects, including the Minato Mirai 21 development. Asukata decided to invite Tamura to join the city government. Tamura worked for Yokohama city for over a decade, and his planning vision was inherited by the city’s officers. Moreover, his accomplishments have encouraged many planners and officers in other local governments. Tamura later lectured on urban policy at university, authored eleven books, and travelled to educate the public on city planning (or ‘machi-zukuri’). In short, Tamura was a leader and pioneer in the field of city planning as an officer of local government.

description: Space discretization of some time-dependent partial differential equations gives rise to systems of ordinary differential equations in additive form whose terms have different stiffness properties. In these cases, implicit methods should be used to integrate the stiff terms while efficient explicit methods can be used for the non-stiff part of the problem. However, for systems with a large number of equations, memory storage requirement is also an important issue. When the high dimension of the problem compromises the computer memory capacity, it is important to incorporate low memory usage to some other properties of the scheme. In this paper we consider Additive Semi-Implicit Runge-Kutta (ASIRK) methods, a class of implicitexplicit Runge-Kutta methods for additive differential systems. We construct two second order 3-stage ASIRK schemes with low-storage requirements. Having in mind problems with stiffness parameters, besides accuracy and stability properties, we also impose stiff accuracy conditions. The numerical experiments done show the advantages of the new methods.
