Genetic investigations of human hemopoiesis : studies of clonality and gene transfer to hemopoietic progenitors
Creators: name: Hogge, Donna Eileen
Publisher: name: University of British Columbia
Year: 2010

description: In most neoplasms malignant change occurs in a single cell which then proliferates. My purpose was to explore methods to study the cell that gives rise to hemopoietic cancer and to investigate the abnormalities at a molecular level. Cytogenetic analysis of cells from individual hemopoietic colonies revealed that monosomy 7 syndrome, a hematologic disorder of childhood, arises in a primitive cell capable of differentiating down both myeloid and erythroid pathways. Long-term bone marrow cultures (LTC) from patients with chronic myelogenous leukemia (CML) favor the growth of Philadelphia chromosome (Ph) negative progenitors which, although cytogenetically normal, could have been part of the malignant clone at a stage prior to the development of the Ph. LTC's were initiated with cells from 2 women with CML who were heterozygous for 2 electrophoretically distinct glucose-6-phosphate dehydrogenase (G6PD) enzyme variants. In one patient, 2/11 progenitors were Ph-negative after 4 to 6 weeks in LTC and 4/30 were nonclonal by G6PD enzyme analysis, i.e. the colonies expressed the enzyme not found in the malignant clone. In this case, karyotypically normal cells were truly normal. Next, gene transfer to human hemopoietic cells was demonstrated using recombinant retrovirus carrying the selectable marker gene, neor. With the K562 human leukemic cell line as targets up to 60% of infected cells became G418 resistant (G418r). Cloned populations of G418r cells showed unique patterns of retroviral integration in K562 DNA. When the target cells were progenitors from normal marrow, CML blood or fetal liver, the highest frequencies of G418r granulocyte-macrophage or large erythroid colonies was 16% and 5% respectively. Experiments infecting bone marrow cells in LTC with neor virus produced up to 2% G418r colonies after as long as 3 weeks in culture. Using v-src virus to infect LTC failed to perturb hemopoiesis, although infection of bone marrow-derived cells in these cultures was documented. In summary: 1. Unique populations of hemopoietic progenitors can be identified in culture using several genetic markers including chromosomes, G6PD analysis or gene transfer. 2. The feasibility of retroviral-mediated gene transfer for use on human hemopoietic cells has been demonstrated.

description: Nonreciprocal resistance, depending on both directions of current ($j$) and magnetic-field ($H$) or magnetization ($M$), is generally expected to emerge in a chiral conductor, and be maximized for $j$ $\parallel$ $H$($M$). This phenomenon, electrical magnetochiral effect (eMChE), is empirically known to increase with $H$ in a paramagnetic or fully ferromagnetic state on chiral lattice or to depend on fluctuation properties of a helimagnetic state. We report here the eMChE over a wide temperature range in the chiral-lattice magnet MnGe in which the spin hedgehog lattice (HL) forms with the triple spin-helix modulation vectors. The magnitude of nonreciprocal resistivity is sharply enhanced in the course of the field-induced structural transition of HL from cubic to rhombohedral form. This is attributed to the enhanced asymmetric electron scatterings by vector spin chirality in association with the large thermal fluctuations of spin hedgehogs.

Silicon Solar Cell Characterization and Modelling

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1325-1328
description: The understanding and therefore the optimization of n+-emitter formation in crystalline silicon using
POCl3-diffusion requires a more detailed knowledge of the dopant source: the PhosphoSilicate Glass (PSG) layer.
The growth of PSG during the phosphorus diffusion process depends on several process parameters, such as
temperature, duration, POCl3-N2 and O2 gas flows. In this work, we compare the uncertainties in various methods
for PSG thickness measurements: by an Atomic Force Microscope (AFM), a profilometer, a Scanning Electron
Microscope (SEM) and a spectroscopic ellipsometer. We then quantify how the PSG thickness is influenced by the
process parameters. We also measure the total amount of phosphorus (P-dose) in the PSG layer using Inductively
Coupled Plasma Optical Emission Spectrometry (ICP-OES) and quantify the P dose in dependence of the process
parameters as well. Finally, by combining both the measured PSG thickness and the dose, we successfully
determine a lower limit for the phosphorus concentration in the PSG layer. It is, depending on the process
parameters, between 7x1021 cm-3 and 1.2x1022 cm-3, which is a remarkably narrow range. These results will help to
improve the phosphorus diffusion model by considering both the PSG growth behavior and PSG composition, and
so will facilitate the development of a predictive model for the POCl3 diffusions process.

description: Software code complexity is a well-studied property to determine software component health. However, the existing code complexity metrics do not directly take into account the fault-proneness aspect of the code. We propose a metric called mutant density where we use mutation as a method to introduce artificial faults in code, and count the number of possible mutations per line. We show how this metric can be used to perform helpful analysis of real-life software projects.

description: In this paper, we describe a harmonic kicker system used in the beam exchange scheme for the Circulator Cooling Ring (CCR) of the Jefferson Lab Electron Ion Collider(JLEIC). By delivering an ultra-fast deflecting kick, a kicker directs electron bunches selectively in/out of the CCR without degrading the beam dynamics of the CCR optimized for ion beam cooling. We will discuss the design principle of the kicker system and demonstrate its performance with various numerical simulations. In particular, the degrading effects of realistic harmonic kicks on the beam dynamics, such as 3D kick field profiles interacting with the magnetized beam, is studied in detail with a scheme that keeps the cooling efficiency within allowable limits.
Fictions of the self : studies in female modernism : Jean Rhys, Gertrude Stein and Djuna Barnes
Creators: name: Groves, Robyn
Publisher: name: University of British Columbia
Year: 2010

description: This thesis considers elements of autobiography and autobiographical fiction in the writings of three female Modernists: Jean Rhys, Gertrude Stein and Djuna Barnes. In chapter 1, after drawing distinctions between male and female autobiographical writing, I discuss key male autobiographical fictions of the Modernist period by D.H. Lawrence, Marcel Proust and James Joyce, and their debt to the nineteenth century literary forms of the Bildungsroman and the Künstlerroman. I relate these texts to key European writers, Andre Gide and Colette, and to works by women based on two separate female Modernist aesthetics: first, the school of "lyrical transcendence"—Dorothy Richardson, Katherine Mansfield and Virginia Woolf—in whose works the self as literary subject dissolves into a renunciatory "female impressionism;" the second group—Rhys, Stein and Barnes--who as late-modernists, offer radically "objectified" self-portraits in fiction which act as critiques and revisions of both male and female Modernist fiction of earlier decades. In chapter 2, I discuss Jean Rhys' objectification of female self-consciousness through her analysis of alienation in two different settings: the Caribbean and the cities of Europe. As an outsider in both situations, Rhys presents an unorthodox counter-vision. In her fictions of the 1930's, she deliberately revises earlier Modernist representations, by both male and female writers, of female self-consciousness. In the process, she offers a simultaneous critique of both social and literary conventions. In chapter 3, I consider Gertrude Stein's career-long experiments with the rendering of consciousness in a variety of literary forms, noting her growing concern throughout the 1920's and 1930's with the role of autobiography in writing. In a close reading of The Autobiography of Alice B. Toklas, I examine Stein's parody and "deconstruction" of the autobiographical form and the Modernist conception of the self based on memory, association and desire. Her witty attack on the conventions of narrative produces a new kind of fictional self-portraiture, drawing heavily on the visual arts to create new prose forms as well as to dismantle old ones. Chapter 4 focuses on Djuna Barnes' metaphorical representations of the self in prose fiction, which re-interpret the Modernist notion of the self, by means of an androgynous fictional poetics. In her American and European fictions she extends the notion of the work of art as a formal, self-referential and self-contained "world" by subverting it with the use of a late-modern, "high camp" imagery to create new types of narrative structure. These women's major works, appearing in the 1930's, mark a second wave of Modernism, which revises and in certain ways subverts the first. Hence, these are studies in "late Modernism" and in my conclusion I will consider the distinguishing features of this transitional period, the 1930's, and the questions it provokes about the idea of periodization in general.

description: Recent trends show that screen printing technology still dominates c-Si solar cell metallization with
over 90% share. Process simplicity and low cost are the major attributes to this, however screen printing has some
shortcomings with respect to fine lines, precision and quality. The purpose of this paper is to develop a practical,
cost effective and simple model together with evaluation procedure that can assist in reducing test time, material
requirement and complexity. To achieve this, we created a mathematical model to predict screen printability in
respect to screen mesh material, meshing parameters and EOM (Emulsion Over Mesh). Finally a new test
procedure is introduced to evaluate screen printed metallization. Both the model and the procedure where tested
on 2 commercial pastes in combination with several screen design parameters. The model proved practical and
user friendly and was verified by testing on 2 different stainless steel (SS) mesh screens and vecry mesh screen
(V-screen) each with different EOM. Combining the model with our proposed test procedure showed that Vscreens
out performed SS screens for similar screen parameters on both pastes tested.

description: We study a cosmological model based on the holographic principle that allows an interaction between dark energy and dark matter with a Hubble infrared cutoff. We adopt an agnostic point of view with respect to the form of the interaction between these dark components by using redshift parameterizations of the dark energy equation of state (DE EoS). Following this approach, we obtain an analytical expression of the Hubble parameter and we test it with four different parameterizations of the DE EoS using currently Pantheon supernovae, Cosmic Chronometers and Galaxy Clustering data sets. Our analyses show that the considered parameterizations on this agnostic proposal allow a late accelerated cosmic expansion in comparison to the results from previous works where specific forms of the interaction are employed but fail to explain this behaviour. Furthermore, we find that our proposal solves the so-called coincidence problem in Cosmology and in this direction shed some light on the problem of the Hubble tension.

description: The measurement technique presented in this paper, provides a very sensitive detection of cracks in polycrystalline
solar wafers and cells, combined with photoluminescence or electroluminescence measurements. The crack detection is
based on illuminating light, entering the wafer (or cell) from the edges and being kept inside the bulk by total internal
reflection. This light is scattered by cracks and inclusions, which then appear with large contrast on a dark background.
An infrared line-scan camera is used as detector. Such, we are able to detect much smaller cracks than with conventional
equipment.
Luminescence signals can be recorded simultaneously with the same camera in the same setup. For the case of
photoluminescence, only the scan line needs to be irradiated by the optical excitation source. This means that the
necessary optical power can be lower and / or exposure times can be shorter. The combination of several measurement
channels (crack detection, luminescence) with different light/excitation sources and a single camera is achieved by a
special application software for a particular frame grabber. By this means, mechanical stability and electric quality
properties can be tested simultaneously.
Self-Similar Evolution of Cosmic-Ray-Modified Quasi-Parallel Plane Shocks

description: Using an improved version of the previously introduced CRASH (Cosmic Ray Acceleration SHock) code, we have calculated the time evolution of cosmic-ray (CR) modified quasi-parallel plane shocks for Bohm-like diffusion, including self-consistent models of Alfven wave drift and dissipation, along with thermal leakage injection of CRs. The new simulations follow evolution of the CR distribution to much higher energies than our previous study, providing a better examination of evolutionary and asymptotic behaviors. The postshock CR pressure becomes constant after quick initial adjustment, since the evolution of the CR partial pressure expressed in terms of a momentum similarity variable is self-similar. The shock precursor, which scales as the diffusion length of the highest energy CRs, subsequently broadens approximately linearly with time, independent of diffusion model, so long as CRs continue to be accelerated to ever-higher energies. This means the nonlinear shock structure can be described approximately in terms of the similarity variable, x/(u_s t), where u_s is the shock speed once the postshock pressure reaches an approximate time asymptotic state. As before, the shock Mach number is the key parameter determining the evolution and the CR acceleration efficiency, although finite Alfven wave drift and wave energy dissipation in the shock precursor reduce the effective velocity change experienced by CRs, so reduce acceleration efficiency noticeably, thus, providing a second important parameter at low and moderate Mach numbers.

description: Responses to colored patterns were collected for a group of 60 naive participants. We explicitly aimed at affective responses, rather than aesthetic judgments, so this is not ‘color harmony’ proper. Patterns were mainly spatially highly structured compositions, the color palettes reminiscent of what is found in generic ‘colorist’ art. Color combinations systematically cover mono-, di-, and trichromatic chromatic chords, whereas there was always an additional achromatic component. This sets the research apart from the bulk of the mainstream literature on ‘color harmony.’ Various ways of analysis are compared. Clustering methods reveal that the responses are highly structured through the teal–orange (cool–warm) dimension. Clustering reveals a large group of mutually concordant participants and various small, idiosyncratic groups. When the data is coarse-grained, retaining only a limited red–blue–yellow palette, the group as a whole appears quite concordant. It is evident that responses are systematic, thus the notion of a universal affective response to color combinations gains some credibility. The precise affective responses are specific because constrained by the seven categories used in the experiment. Thus, the systematic structure is perhaps to be understood as the generic result. We discuss tangencies with various traits found with ‘colorist’ art styles.

The decreasing rate is higher for less smooth deformations.

Silicon Solar Cell Improvements

description: 27th European Photovoltaic Solar Energy Conference and Exhibition; 1982-1984
description: Silicon nanowires (NW) can increase the efficiency of crystalline silicon solar cells manufactured
using a conventional equipment-set. NWs reduce reflection and increase absorption. Here, we present reflection
measurements of NWs, showing low reflection over a broad range of incident wavelengths and angles; we measure
reflection of near normal-incidence light that is less than 1% for a weighted average over the solar spectrum. We also
show that NWs increase the optical path length within a device, allowing the absorption of the silicon to approach the
Lambertian light-trapping limit. We propose a practical process for manufacturing NW cells, where the NWs
eliminate the need for traditional anti-reflection coatings and light-trapping techniques, contributing to overall perwatt
cost reductions of $0.05-0.10/Wp. The NW fabrication process is independent of crystallographic orientation,
and therefore especially well-suited for multicrystalline cells. Our cell design and passivation are optimized to abate
any increased surface recombination in NWs, as evinced by long minority carrier lifetimes measured in passivated
wafers with NWs, and measurements of NW cells with high blue external quantum efficiency (EQE) and high efficiency.

description: The dynamics of entanglement and fidelity for a subsystem of two separate spin-1/2 qubits prepared in Bell states is investigated. One of the subsystem qubit labelled $A$ is under the influence of a Heisenberg XY spin-bath, while another one labelled $B$ is uncoupled with that. We discuss two cases: (i) the number of bath spins $N\to\infty$; (ii) $N$ is finite: N=40. In both cases, the bath is initially prepared in a thermal equilibrium state. It is shown that the time dependence of the concurrence and the fidelity of the two subsystem qubits can be controlled by tuning the parameters of the spin-bath, such as the anisotropic parameter, the temperature and the coupling strength with qubit $A$. It is interesting to find the dynamics of the concurrence is independent of four different initial Bell states and that of the fidelity is divided into two groups.

description: This article introduces a fully automated verification technique that permits to analyze real-time systems described using a continuous notion of time and a mixture of operational (i.e., automata-based) and descriptive (i.e., logic-based) formalisms. The technique relies on the reduction, under reasonable assumptions, of the continuous-time verification problem to its discrete-time counterpart. This reconciles in a viable and effective way the dense/discrete and operational/descriptive dichotomies that are often encountered in practice when it comes to specifying and analyzing complex critical systems. The article investigates the applicability of the technique through a significant example centered on a communication protocol. More precisely, concurrent runs of the protocol are formalized by parallel instances of a Timed Automaton, while the synchronization rules between these instances are specified through Metric Temporal Logic formulas, thus creating a multi-paradigm model. Verification tests run on this model using a bounded validity checker implementing the technique show consistent results and interesting performances.

of the incident solar light. Two types of MLAs with square and cylindrical micropatterns were
developed and then respectively mounted onto a triple junction GaAs solar cell as both an incident sunlight
manipulator and a surface encapsulation layer. Under the air mass (AM) 1.5 irradiation, the square MLA-mounted
cell with an optimal optical spacer showed short-circuit current (ISC) of 13.27 mAcm-2 and power conversion
efficiency (PCE) of 22.25 %, and the same cell mounted with the cylindrical MLA with an optimal optical spacer
showed similar ISC of 13.17 mAcm-2 and PCE of 22.10 %. The achieved output powers are ~19.5 % higher than that
of the general glass-packaged cell as a reference and even 10 % higher than that of the pristine cell without a cover.
The condensing MLA can replace a conventional glass (or film) as a encapsulation layer to efficiently improve
photovoltaic performances of GaAs-based solar cells.

The amplitude and wave number of the periodic solution for the spin current have the different contribution to the width, velocity, and the amplitude of soliton solution, respectively. Moreover, we found that the soliton can be trapped only in space with a proper condition. At last we analyze the modulation instability and discuss dark solitary wave propagation for the spin current on the background of a periodic solution. In some special cases the solution can be expressed by the linear combination of periodic solution and soliton solution.

description: The Miniaturized Detector for Application in Space (MIDAS) is a compact device with dimensions 5 x 5 x 1 cm3 which combines position sensitive Si detectors and a fast neutrons spectrometer. MIDAS is developed with purpose to act as a linear energy transfer (LET) spectrometer for the charged particles and measure dose and dose equivalent from both charged particles and neutrons. It is based on fully depleted monolithic active Si pixel sensors for the charged track and energy deposition measurements, while a plastic scintillator read out by a silicon photomultiplier is used to determine energy depositions from fast neutrons. A simulation study of the detector response in galactic cosmic ray (GCR) radiation fields with the aid of GEANT4 has been performed. Energy depositions and hit pixel addresses have been used to reconstruct tracks and calculate LET spectra. A method to calculate $LET\infty$ in water from the measured LET has been elaborated.

description: A newly developed characterisation method at Fraunhofer ISE allows a precise evaluation of via
contact formation by determining the via resistance for metal wrap through (MWT) solar cells. Based on a
previously presented via characterisation method for test structures, the new measurement setup is able to
automatically characterise via-contacts directly on a solar cell. Due to its flexible design, the setup is adjustable
to any cell size and any contact arrangement. The modified four point probe measurement setup with flat
electrodes on the front and spiky electrodes on the rear of the cell facilitates the measurement and precise the
alignment on a each MWT-via contact. The new device is an important characterisation instrument for the
evaluation and optimization of via-contacts directly on cell level.
Identit� in transito: prove di riscrittura del s� nella memorialistica e narrativa femminile irano-americana

description: Before and after the Iranian Revolution, the experience of restrictions and gender confinement drove many Iranian women writers to fight for their forbidden role. What many of them now call their first exile at home went on until the chance of migration, above all to Europe and to the Usa, changed the perils of writing under Iranian censorship into a free, but unbalanced condition aware of cultural dissociations.
Those dissociations are not simply due to diasporic estrangement, but to a more confused doubling, which is rooted in a quest for the self that passes through hyphenation and in-betweenness. Moreover, if the veil often emerges as a narrative symbol of women?s oppression, it sometimes acquires the valency of a dramatic ?fourth wall?.
This thesis aims to overthrow that ?invisible wall?, in order to show a relationship between dramatization and new writing by the women of the Iranian diaspora. In line with Brechtian epic drama based on the concept of estrangement, it will explore estrangement both as an existential condition and as the distance required to rewrite the self through new roles.
More in detail, if the author lives between two worlds and tries to depict their dualisms, she also becomes the playwright of her past and present selves. The metaphors and dualisms will be examined through a comparison of some memoirs and novels by Iranian-American women writers ? such as Azadeh Moaveni, Firoozeh Dumas, Nahid Rachlin, Porochista Khakpour and Azar Nafisi ? coming from different generations and cultural heritages. Each narration will be analysed as a dramatic scene of memories and linguistic splits, which dramatize recurring senses of estrangement and turn them into a more ?visible wall? of identities in transit.

description: Existing emotion-aware conversational models usually focus on controlling the response contents to align with a specific emotion class, whereas empathy is the ability to understand and concern the feelings and experience of others. Hence, it is critical to learn the causes that evoke the users' emotion for empathetic responding, a.k.a. emotion causes. To gather emotion causes in online environments, we leverage counseling strategies and develop an empathetic chatbot to utilize the causal emotion information. On a real-world online dataset, we verify the effectiveness of the proposed approach by comparing our chatbot with several SOTA methods using automatic metrics, expert-based human judgements as well as user-based online evaluation.

The convenience yield : a model and empirical examination of the relationship between commodity futures prices and current spot prices
Creators: name: Howe, Maureen E.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the cross-sectional and time series variation between commodities futures prices and current prices. The 'Theory of Storage' states that the difference between the two prices will be a function of two factors: The first is the cost of storing the commodity over the term of the futures contract (carrying costs). The second factor is the value of the convenience yield. The convenience yield is a concept which evolved from the theory of storage and is explained as the benefit which accrues to the individual or firm that holds the commodity in storage but does not accrue to the holder of the futures contract. It is generally assumed that the value of a commodity's convenience yield is decreasing in the aggregate inventory available and some indirect empirical support has been generated for this assumption, however, an economic model has not been provided which derives the result. There are two objectives of this thesis: The first is to provide a model of the convenience yield which explains the relationship between the level of inventories and the value of the convenience yield. The second objective is to empirically test the predictions of the model. The model provided shows the convenience yield to be decreasing in the level of aggregate inventory. In addition, the value of the convenience is found to be related to the time-series process of shocks to demand. An analogy is drawn between the convenience yield and an option with a stochastic exercise price. Using futures price data and aggregate inventory data, the empirical implications of the model are tested. The results support the hypothesis that a commodity's convenience yield is decreasing in aggregate inventory. Some evidence is also provided that the convenience yield is decreasing in the correlation between shocks to demand.
Linear-Programming Decoding of Nonbinary Linear Codes

description: A framework for linear-programming (LP) decoding of nonbinary linear codes over rings is developed. This framework facilitates linear-programming based reception for coded modulation systems which use direct modulation mapping of coded symbols. It is proved that the resulting LP decoder has the 'maximum-likelihood certificate' property. It is also shown that the decoder output is the lowest cost pseudocodeword. Equivalence between pseudocodewords of the linear program and pseudocodewords of graph covers is proved. It is also proved that if the modulator-channel combination satisfies a particular symmetry condition, the codeword error rate performance is independent of the transmitted codeword. Two alternative polytopes for use with linear-programming decoding are studied, and it is shown that for many classes of codes these polytopes yield a complexity advantage for decoding. These polytope representations lead to polynomial-time decoders for a wide variety of classical nonbinary linear codes. LP decoding performance is illustrated for the [11,6] ternary Golay code with ternary PSK modulation over AWGN, and in this case it is shown that the performance of the LP decoder is comparable to codeword-error-rate-optimum hard-decision based decoding. LP decoding is also simulated for medium-length ternary and quaternary LDPC codes with corresponding PSK modulations over AWGN.

description: This paper examines the quality of citizenship data in self-reported survey responses compared to administrative records and evaluates options for constructing an accurate count of resident U.S. citizens. Person-level discrepancies between survey-collected citizenship data and administrative records are more pervasive than previously reported in studies comparing survey and administrative data aggregates. Our results imply that survey-sourced citizenship data produce significantly lower estimates of the noncitizen share of the population than would be produced from currently available administrative records; both the survey-sourced and administrative data have shortcomings that could contribute to this difference. Our evidence is consistent with noncitizen respondents misreporting their own citizenship status and failing to report that of other household members. At the same time, currently available administrative records may miss some naturalizations and capture others with a delay. The evidence in this paper also suggests that adding a citizenship question to the 2020 Census would lead to lower self-response rates in households potentially containing noncitizens, resulting in higher fieldwork costs and a lower-quality population count.

description: The performance of photovoltaic (PV) modules in the field is significantly affected by the ambient conditions it is subjected to during its operational life. The ambient conditions typically considered the most important in this respect are temperature, wind speed and moisture. In terms of temperature, the impact can be manifold:
• The overall module temperature impacts directly the module performance: increased temperatures at the cell level lead to a drop in VOC which negatively impact the overall performance;
• Local variations in illumination and/or temperature (temporally as well as spatially) can cause mismatch between
the cells connected in series;
• Thermal cycling mechanically stresses the module and may cause cracking and delamination of the different layers in the module (cell, interconnect metallization, encapsulant, glass, back sheet) over time.
In short, the operational temperature has an important impact on the potential energy yield of PV modules, either through suboptimal performance of the different cells in the module, or through a reduction of the operational lifetime (reliability issues related to thermal cycling). Here, the aim is to understand by 3D FEM modeling and experimental calibration the thermal behavior in detailed spatial and fine temporal regime of modules to determine potential cell- and module-level improvements. In particular we want to build a thermal model for the MWT c-Si wafer-based modules.

description: In this paper we study the cosmological evolution of the holographic dark energy in a cyclic universe, generalizing the model of holographic dark energy proposed by Li. The holographic dark energy with $c<1$ can realize a quintom behavior; namely, it evolves from a quintessence-like component to a phantom-like one. The holographic phantom energy density grows rapidly and dominates the late-time expanding phase, helping realize a cyclic universe scenario in which the high energy regime is modified by the effects of quantum gravity, causing a turnaround (and a bounce) of the universe. The dynamical evolution of holographic dark energy in the regimes of low energy and high energy is governed by two differential equations, respectively. It is of importance to link the two regimes for this scenario. We propose a link condition giving rise to a complete picture of holographic evolution of a cyclic universe.

description: This study focuses on designing and developing a mathematically based quadcopter rotational dynamics simulation framework for testing reinforcement learning (RL) algorithms in many flexible configurations. The design of the simulation framework aims to simulate both linear and nonlinear representations of a quadcopter by solving initial value problems for ordinary differential equation (ODE) systems. In addition, the simulation environment is capable of making the simulation deterministic/stochastic by adding random Gaussian noise in the forms of process and measurement noises. In order to ensure that the scope of this simulation environment is not limited only with our own RL algorithms, the simulation environment has been expanded to be compatible with the OpenAI Gym toolkit. The framework also supports multiprocessing capabilities to run simulation environments simultaneously in parallel. To test these capabilities, many state-of-the-art deep RL algorithms were trained in this simulation framework and the results were compared in detail.
