description: In this work, we introduce GRChombo: a new numerical relativity code which incorporates full adaptive mesh refinement (AMR) using block structured Berger-Rigoutsos grid generation. The code supports non-trivial "many-boxes-in-many-boxes" mesh hierarchies and massive parallelism through the Message Passing Interface (MPI). GRChombo evolves the Einstein equation using the standard BSSN formalism, with an option to turn on CCZ4 constraint damping if required. The AMR capability permits the study of a range of new physics which has previously been computationally infeasible in a full 3+1 setting, whilst also significantly simplifying the process of setting up the mesh for these problems. We show that GRChombo can stably and accurately evolve standard spacetimes such as binary black hole mergers and scalar collapses into black holes, demonstrate the performance characteristics of our code, and discuss various physics problems which stand to benefit from the AMR technique.

description: The use of surrogate models is now very widespread in engineering activities to
replace high-fidelity models, compu-tation codes or simulators that are too complex
or time consuming. This is especially the case in the aerospace field: although physical
models are available, derived from aerodynamics, structural dynamics or flight mechanics,
quite often they cannot be used just as they are. Hence, simplified representations
need to be developed in order to achieve some tasks involving for instance optimization,
parameter identification, embedded implementations, and so on. This paper illustrates
some of these aspects in the field of aircraft flight control systems. After outlining the
characteristics of the preferred surrogate models, the techniques that have been developed
for constructing these models efficiently are presented. Then, three relevant
off-line and on-line applications are described, with the surrogate models being respectively
used: to create parsimonious representations useful for building Linear Fractional
Representations for analysis and design of control laws, as intermediate models in the
modeling of rigid aircraft to facilitate the identification process of aerodynamic nonlinearities
from flight tests, and to obtain embeddable models used for the virtual sensing
of some flight parameters required to schedule the control/protection laws.

description: The nature of cosmological dark matter finds its explanation in physics beyond the Standard model of elementary particles. The landscape of dark matter candidates contains a wide variety of species, either elusive or hardly detectable in direct experimental searches. Even in case, when such searches are possible the interpretation of their results implies additional sources of information, which provide indirect effects of dark matter. Some nontrivial probes for the nature of the dark matter are presented in the present issue.

description: The top quark plays a central role in many New Physics scenarios and in understanding the details of Electro-Weak Symmetry Breaking. In the short- and mid-term future, top-quark studies will mainly be driven by the experiments at the Large Hadron Collider. Exploration of top quarks will, however, be an integral part of particle physics studies at any future facility and an $e^+ e^-$ collider will have a very comprehensive top-quark physics program. We discuss the possibilities of testing NP in the top-quark sector within a composite Higgs scenario through deviations from the Standard Model in top pair production for different Centre-of-Mass energy options of a future $e^+e^-$ machine. In particular, we focus on precision studies of the top-quark sector at a CM energy ranging from 370 GeV up to 3 TeV.

Glassy dynamics in confinement: Planar and bulk limit of the mode-coupling theory

description: We demonstrate how the matrix-valued mode-coupling theory of the glass transition and glassy dynamics in planar confinement converges to the corresponding theory for two-dimensional (2D) planar and the three-dimensional bulk liquid, provided the wall potential satisfies certain conditions. Since the mode-coupling theory relies on the static properties as input, the emergence of a homogeneous limit for the matrix-valued intermediate scattering functions is directly connected to the convergence of the corresponding static quantities to their conventional counterparts. We show that the 2D limit is more subtle than the bulk limit, in particular, the in-planar dynamics decouples from the motion perpendicular to the walls. We investigate the frozen-in parts of the intermediate scattering function in the glass state and find that the limits time $t\to \infty$ and effective wall separation $L\to 0$ do not commute due to the mutual coupling of the residual transversal and lateral force kernels.

description: Wireless Sensor Networks (WSNs) are the key components of the emerging Internet-of-Things (IoT) paradigm. They are now ubiquitous and used in a plurality of application domains. WSNs are still domain specific and usually deployed to support a specific application. However, as WSN nodes are becoming more and more powerful, it is getting more and more pertinent to research how multiple applications could share a very same WSN infrastructure. Virtualization is a technology that can potentially enable this sharing. This paper is a survey on WSN virtualization. It provides a comprehensive review of the state-of-the-art and an in-depth discussion of the research issues. We introduce the basics of WSN virtualization and motivate its pertinence with carefully selected scenarios. Existing works are presented in detail and critically evaluated using a set of requirements derived from the scenarios. The pertinent research projects are also reviewed. Several research issues are also discussed with hints on how they could be tackled.

VIPER meets CRIRES+: Reaching 3 m/s in the NIR
Creators: name: Köhler, Jana
Publisher: name: Zenodo
Year: 2023

description: During the last years, Radial Velocity (RV) measurements became an admired tool for the discovery and study of exoplanets, coming along with a number of new instruments and data reduction codes. One of these new instruments, which is meant to reach a RV precision of around 3 m/s in the NIR, is the updated CRyogenic high-resolution InfraRed Echelle Spectrograph (CRIRES+). In this context, I will present our data reduction code VIPER (Velocity and IP EstimatoR), which will be soon available as the official RV pipeline for CRIRES+. VIPER is based on the method as described in Butler et al. 1996, using imprinted cell lines as wavelength calibration. As the spectrum in the NIR is increasingly contaminated by telluric lines, additionally VIPER is able to model imprinted tellurics, as well as creating telluric-free stellar templates. Without the need of any additional telluric correction codes, VIPER allows a fast and easy way of RV estimation. To show its efficiency, I will present current results from the CRIRES+ commissioning and how we are able to reach a RV precision of a few m/s on short and long time scales in K-band.

description: Der westafrikanische Monsun ist einer der markantesten Bestandteile des Klimas über Westafrika. Er ist die Hauptquelle für Regen über der semi-ariden Sahelzone und hat damit einen entscheidenden Einfluss auf die Sozioökonomie dieser Regionen, die großteils auf Landwirtschaft angewiesen sind. Allerdings stellt das komplexe Zusammenspiel der großräumigen Zirkulation mit kleinskaligen Wolken- und Regenprozessen eine große Herausforderung dar, die atmosphärischen Zweige des Wasserkreislaufs während des Monsuns verlässlich zu quantifizieren. Der Fokus der zugrundeliegenden Arbeit liegt daher auf der Analyse von troposphärischem Wasserdampf und seiner Einflussfaktoren während des westafrikanischen Monsuns. Für diesen Zweck werden Verteilungen der Wasserdampfisotopologe H$_2$O and HDO (standardmäßig als $\delta$D angegeben) gemeinsam betrachtet, da diese fundamentale Rückschlüsse über Feuchtepfade und -prozesse ermöglichen. In einem dreistufigen Konzept nutzt diese Arbeit beobachtungs- und modellgestützte {H$_2$O, $\delta$D} Verteilungen zur Analyse von Effekten von Transport- und Feuchteprozessen im Zusammenhang mit dem Monsun. Im ersten Schritt wird ein neuartiger Datensatz von troposphärischen {H$_2$O, $\delta$D}-Paaren auf der Basis von globalen and täglichen Fernerkundungsdaten des Satellitensensors Metop/IASI erzeugt. Um Isotopendaten aus Modellanalysen mit diesem neuen Datensatz vergleichbar zu machen, wird ein sogenannter Retrieval Simulator entwickelt. Der zweite Schritt zielt auf eine modellgestützte Prozessanalyse unter Verwendung von Luftmassen-Trajektorien, um eine aussagekräftige Interpretation von {H$_2$O, $\delta$D}-Verteilungen zu ermöglichen. Darauf aufbauend wird im dritten Schritt eine umfangreiche und mehrskalige Analyse der IASI {H$_2$O, $\delta$D}-Verteilungen über der Sahelzone mit Fokus auf den Monsun durchgeführt. Dies beinhaltet Simulationen mit den numerischen Wettermodellen ICON-ART$_\mathrm{iso}$ und COSMO$_\mathrm{iso}$ sowie Niederschlagsbeobachtungen von der NASA (GPM IMERG). Die Synthese dieser Datensätze und Methoden ermöglicht, charakteristische {H$_2$O, $\delta$D}-Signale über der Sahelzone zu identifizieren und diese auf eindeutige Effekte der Luftmassenmischung und mikrophysikalischen Prozesse wie Kondensation, Verdunstung und Äquilibrierung von Regentropfen zurückzuführen. Insgesamt verdeutlicht diese Studie das Potential von {H$_2$O, $\delta$D}-Verteilungen von IASI zusammen mit hoch aufgelösten Modellrechnungen sowie detaillierten Prozessanalysen zur Untersuchung des troposphärischen Feuchtebudgets. Damit unterstreicht diese Arbeit den grundsätzlichen Wert der Wasserdampfisotopologie für die Analyse des hydrologischen Kreislaufs.

description: The Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission observed comet C/2013 A1 (Siding Spring) three times at 3.4 μm and 4.6 μm as the comet approached Mars in 2014. The comet is an extremely interesting target since its close approach to Mars in late 2014 will be observed by various spacecraft in-situ. The observations were taken in 2014 Jan., Jul. and Sep. when the comet was at heliocentric distances of 3.82 AU, 1.88 AU, and 1.48 AU. The level of activity increased significantly between the Jan. and Jul. visits but then decreased by the time of the observations in Sep., approximately 4 weeks prior to its close approach to Mars. In this work we calculate Af\r{ho} values, and CO/CO2 production rates.

description: We have analyzed long-term wind speed time-series from five field sites up to a height of 300 m from the ground. Structure function-based scaling analysis has revealed that the scaling exponents in the mesoscale regime systematically depend on height. This anomalous behavior is likely caused by the buoyancy effects. In the framework of the extended self-similarity, the relative scaling exponents portray quasi-universal behavior.

description: A gestão de pessoas deve atuar como um componente estratégico visando a utilização planejada de abordagens próprias aos colaboradores da instituição com a finalidade de implementação e junção das estratégias da organização. É a busca pela retenção, desenvolvimento, engajamento e motivação dos funcionários para que satisfaçam as suas necessidades como seres humanos e proporcionem assim a satisfação das necessidades da organização e dos clientes. Na presente pesquisa, considerou-se que uma ação vinculada à perspectiva de gestão de pessoas promoveria a satisfação das necessidades dos funcionários fazendo com que eles se mostrassem mais engajados e motivados no trabalho. Neste caso, o entendimento foi de que, a partir do momento em que a instituição fornece o meio para que o colaborador se qualifique, ele se sentirá mais motivado e engajado. Nessa perspectiva, o objetivo central dessa dissertação consistiu em verificar se os docentes do Instituto Federal de Educação, Ciência e Tecnologia do Norte de Minas Gerais (IFNMG) sentiam-se motivados e engajados após a oportunidade de afastamento para qualificação, oferecida pelo órgão, e o retorno do servidor às suas atividades. Para que essa situação fosse verificada, procedeu-se o estudo das teorias de engajamento no trabalho propostas por Kahn (1990) e Schaufeli et al. (2002), e o estudo das teorias a respeito da motivação no trabalho propostas por Maslow (Teoria da Hierarquia das Necessidades), Alderfer (Teoria ERG), Vroom (Teoria da Expectativa), McClelland (Teoria das Necessidades), Adams (Teoria da Equidade), Herzberg (Teoria dos Dois Fatores), Locke e Latham (Teoria da Fixação de Metas). O estudo foi feito em uma abordagem qualitativa, sendo do tipo exploratório e utilizando como formas de investigação a pesquisa de campo, bibliográfica e o estudo de caso. Os dados foram coletados por meio de análise documental, pesquisa bibliográfica e entrevistas com os docentes da instituição. Os resultados indicaram que os professores do IFNMG que se afastaram para mestrado ou doutorado, beneficiados pela ação do órgão, sentem-se mais engajados e motivados no trabalho após o retorno às suas atividades. Indicaram ainda que a obtenção do título acadêmico é essencial tanto para vida pessoal quanto profissional dos docentes, e que o afastamento para qualificação é um fator diferencial e está atrelado à questão da motivação no trabalho.

Year: 2024

description: Gay men living with HIV experience stigma related to their dual minority statuses. Despite advancements in HIV biomedicine and societal acceptance of sexual minorities over thirty years, this demographic continues to report poorer psychosocial outcomes compared to the general population. This thesis explores the contributing factors that influence how sexual orientation and HIV stigmas are experienced, adaptive coping responses employed by men, and challenges faced when accessing HIV support services. Findings highlight the continued psychosocial disparities at an individual, sociocultural and structural level. Recommendations from this thesis can assist researchers, clinicians and HIV services in both stigma evaluation and reduction.

description: We report on the single crystal properties of the novel U$_{2}$RhIn$_{8}$ compound studied in the context of parent URhIn$_{5}$ and UIn$_{3}$ systems. The compounds were prepared by In self-flux method. U$_{2}$RhIn$_{8}$ adopts the Ho$_{2}$CoGa$_{8}$-type structure with lattice parameters a $= 4.6056(6)$ Å and c $= 11.9911(15)$ Å. The behavior of U$_{2}$RhIn$_{8}$ strongly resembles that of the related URhIn$_{5}$ and UIn$_{3}$ with respect to magnetization, specific heat and resistivity except for magnetocrystalline anisotropy developing with lowering dimensionality in the series UIn$_{3}$ vs. U$_{2}$RhIn$_{8}$ and URhIn$_{5}$. U$_{2}$RhIn$_{8}$ orders antiferromagnetically below T$_{\textrm{N}}$ $= 117$ K and exhibits a slightly enhanced Sommerfeld coefficient $γ= 47$ mJ$\cdot$mol$^{-1}\cdot$K$^{-2}$. Magnetic field leaves the value of Néel temperature for both URhIn$_{5}$ and U$_{2}$RhIn$_{8}$ unaffected up to 9 T. On the other hand, T$_{\textrm{N}}$ is increasing with applying hydrostatic pressure up to 3.2 GPa. The weak temperature dependence of $χ(T)$ in all studied compounds might be attributed to the mainly itinerant nature of 5f electrons. The character of uranium 5f electron states of U$_{2}$RhIn$_{8}$ was studied by first principles calculations based on the density functional theory. The overall phase diagram of U$_{2}$RhIn$_{8}$ is discussed in the context of magnetism in the related URhX$_{5}$ and UX$_{3}$ (X = In, Ga) compounds.

description: The release of greenhouse gases (GHG) like methane plays a key role in driving the climate change. With the optimization of atmospheric chemistry climate models, the accuracy in predicting future scenarios is improved, which is an important factor in our efforts to mitigate climate change. The objective of this work is to introduce three methods for the quantification and adjustment of wrong or missing emissions in well-established GHG-inventories, which are used as input data for emissions in atmospheric chemistry transport or climate models. Beside a straight-forward upscaling method and a regridding method based on reported emission data, we present the WALLACE workflow, a new and efficient method to quantify GHG emissions based on satellite measurements. The overall goal of WALLACE is to highlight emission hotspots and it therefore includes spatiotemporal proxy data and a selection algorithm. For the North Sea as a show case region we apply WALLACE to quantify methane emission fluxes of oil and gas platforms. The adjusted emissions are implemented as pointsources into the ICOsahedral Nonhydrostatic model with Aerosols and Reactive Trace gases (ICON-ART) and idealized simulations are performed to compare the three methods with reference simulations to derive their impact on the spatial distribution of methane and its global and regional budget. For all three adjustment methods our model reveals a distribution of methane on the northern hemisphere and an effect on the European continent. For a quantification of the impact we evaluate the influence of the adjusted North Sea platform emissions on the radiative forcing. Additionally, we take a look at the anti-correlation between methane and its main sink in the atmosphere, the hydroxyl radical (OH), which is implemented as a simple OH-chemistry mechanism into the routines of the model. This work makes a new and innovative contribution to achieve an accurate quantification of environmentally harmful gases that drive man-made climate change.

description: Since their early development in the 1970s with the introduction of fly-by-wire
technology, control systems have considerably evolved. Thanks to powerful
on-board computers whose capacities have undergone an exponential growth over the
past thirty years, together with the development of enhanced sensors and actuators,
the complexity of aerospace control systems is almost no longer bounded today. This
is true at least from a technological viewpoint. Control engineers should, however, keep
in mind that there are many risks in developing unnecessarily complex systems whose
validation will become a real issue. In this world, where technological constraints
have been considerably relaxed and where autonomous systems have become a
universal Holy Grail, a good balance must be found between the design and validation
phases in the development of control systems. Some complexity is inevitable during
the design phase to cope with that of the plant itself, as well as with the required level
of autonomy. However, complexity must be controlled, so that the validation phase
remains as quick and cheap as possible.
In this general context of rapidly growing complexity, the development of efficient control
design and analysis tools has become a critical issue. Here again, the exponential growth
in computing capacity has played a key role and contributed to a rapid development of
many fields in control theory. As a result, if one focuses at least on the linear control
framework and its numerous extensions (such as robust control theory, parameter-varying
control and adaptive control, to cite a few), a high level of maturity is now reached.
However, the gap between theory and practice remains to be filled. This is the main
focus of this thirteenth issue of Aerospace Lab, which is dedicated to the most
recent techniques for the design and validation of Aerospace Control Systems, with
a particular emphasis on Matlab-oriented tools and toolboxes together with realistic
applications. This issue is also strongly connected to the SMAC (Systems Modeling
Analysis  Control) toolbox developed by ONERA.

Contested Health Care System in Berlin: Are Illegalized Migrants Becoming Urban Citizens?

description: This article argues for an urban citizenship perspective which explores the struggle for rights and the everyday practices of illegalized migrants. Analyzing the concept of Anonymized Health Certificates as a result of such a struggle allows for examination of urban citizenship in this context. The implementation of the Anonymized Health Certificates program would facilitate access to medical care for people who live in the city of Berlin but are excluded from this right due to their lack of residency status. However, such a perspective also makes it possible to examine the limitation of the Anonymized Health Certificates, which would allow illegalized migrants in Berlin to circumvent access barriers, while at the same time the exclusion mechanisms of these barriers would remain uncontested at the national level. Whilst Anonymize Health Certificates will greatly improve access to medical care, illegalized migrants have by no means been passive subjects and have been actively rejecting their exclusion from health care: Practices include sharing health insurance cards with friends, visiting doctors who help for free as a form of solidarity, and sharing information about these doctors within their social networks. Even if they do not contest the social order visibly, they refuse to passively accept their social exclusion. Illegalized migrants perform such practices of urban citizenship in their everyday life as they actively take ownership of their rights to participate in urban life, even whilst being formally denied these rights.
Brightness temperature constraints from interferometric visibilities

description: The brightness temperature is an effective parameter that describes the physical properties of emitting material in astrophysical objects. It is commonly determined by imaging and modeling the structure of the emitting region and estimating its flux density and angular size. Reliable approaches for visibility-based estimates of brightness temperature are needed for interferometric experiments in which poor coverage of spatial frequencies prevents successful imaging of the source structure, for example, in interferometric measurements made at millimeter wavelengths or with orbiting antennas. Such approaches can be developed by analyzing the relations between brightness temperature and visibility amplitude and its r.m.s. error. A method is introduced for directly calculating the lower and upper limits of the brightness temperature from visibility measurements. The visibility-based brightness temperature estimates are shown to agree well with the image-based estimates obtained in the 2\,cm MOJAVE survey and the 3\,mm CMVA survey, with good agreement achieved for interferometric measurements at spatial frequencies exceeding $\approx 2\times 10^8$. The method provides an essential tool for constraining brightness temperature in all interferometric experiments with poor imaging capability.

description: The inherent structural instability and very low bioavailability of ligustilide (Lig) lead to the limited application of the clinical neuroprotection. We developed a stabilised method for Lig, which involved a chemical synthesis between cyclopropylamine and the active phthalides extract included Lig from Angelica sinensis (Oliv) Diles or Ligusticum chuanxiong Hort, which generated correspond phthalide derivatives by nucleophilic additive and substituted reaction. During this process, four phthalide derivatives have been obtained and two compounds (3 and 4) stands out as an unprecedented dimeric phthalide entity. This research has meticulously delineated the stabilised pathway and polymerisation mechanics of Lig or its derivatives, an oxygen/glucose deprived PC12 cells experiment model utilised to screen the anti-stroke activity of this isolated Lig derivatives and the results supported this chemical transformation could achieve the stabilised goal of Lig and improved its anti-oxygen/glucose deprived activity.

description: Chloroplasts (and other plastids) harbor their own genetic material, with a bacterial-like gene-expression systems. Chloroplast RNA metabolism is complex and is predominantly mediated by nuclear-encoded RNA-binding proteins. In addition to these nuclear factors, the chloroplast-encoded intron maturase MatK has been suggested to perform as a splicing factor for a subset of chloroplast introns. MatK is essential for plant cell survival in tobacco, and thus null mutants have not yet been isolated. We therefore attempted to over-express MatK from a neutral site in the chloroplast, placing it under the control of a theophylline-inducible riboswitch. This ectopic insertion of MatK lead to a variegated cotyledons phenotype. The addition of the inducer theophylline exacerbated the phenotype in a concentration-dependent manner. The extent of variegation was further modulated by light, sucrose and spectinomycin, suggesting that the function of MatK is intertwined with photosynthesis and plastid translation. Inhibiting translation in the transplastomic lines has a profound effect on the accumulation of several chloroplast mRNAs, including the accumulation of an RNA antisense to rpl33, a gene coding for an essential chloroplast ribosomal protein. Our study further supports the idea that MatK expression needs to be tightly regulated to prevent detrimental effects and establishes another link between leaf variegation and chloroplast translation.

description: This is part II of a trio of review papers describing how finite element models can aid in the understanding of the thermal structure of subduction zones. This PDF is a preprint of the revised version submitted to Progress in the Earth and Planetary Science.Abstract:
The thermal structure of subduction zones is fundamental to our understanding of the physical and chemical processes that occur at active convergent plate margins. These include magma generation and related arc volcanism, shallow and deep seismicity, and metamorphic reactions that can release fluids. Computational models can predict the thermal structure to great numerical precision when models are fully described but this does not guarantee accuracy or applicability. In a trio of companion papers the construction of thermal subduction zone models, their use in subduction zone studies, and their link to geophysical and geochemical observations is explored. In this part~II the finite element techniques that can be used to predict thermal structure are discussed in an introductory fashion along with their verification and validation.

Which Fundamental Constants for CMB and BAO?

description: We use the three-scale framework of Hu et al. to show how the Cosmic Microwave Background anisotropy spectrum depends on the fundamental constants. As expected, the spectrum depends only on \emph{dimensionless} combinations of the constants, and we emphasize the points that make this generally true for cosmological observables. Our analysis suggests that the CMB spectrum shape is mostly determined by $α^2m_e/m_p$ and the proton-CDM-particle mass ratio, $m_p/\mchi$. The distance to the last-scattering surface depends on $Gm_p\mchi/\hbar c$, so published CMB observational limits on time variations of the constants implicitly assume the time-independence of this quantity, as well as assuming a flat-\lcdm~cosmological model. On the other hand, low-redshift BAO, $H_0$ and baryon-mass-fraction measurements can be combined with the \emph{shape} of the CMB spectrum to give information that is largely independent of these assumptions. In particular we show that the pre-recombination values of $G\mchi^2/\hbar c$, $m_p/\mchi$ and $α^2m_e/m_p$ are equal to their present values at a precision of $\sim15\%$.

description: Drugs that target epigenetic mechanisms like histone posttranslational modifications (hPTMs), called epidrugs, can be used in clinical trials trying to reprogram the epigenetic landscape in the cancer epigenome. This holds great promise in patient care to prevent disease states. Nonetheless, the mapping of hPTMs, with the aid of mass spectrometry based proteomics (MS) has not been extensively described. Therefore we have made the first untargeted map of the histone code for 21 T-cell acute lymphoblastic leukaemia cell lines. However, extracting biological information from this map is not trivial because of the complexity of the histone code. Because of this, data sharing and reuse is important to facilitate transfer of knowledge and information. We have pre-processed the raw data into a single platform-independent Progenesis QIP project that is fully accessible so that other researchers can use this browsable template. Because data visualisation and pre-processing are important first steps when analysing data, but are often not trivial for biologists without programming experience, we have developed an accompanying shiny app in which users can intuitively visualise the different peptidoforms present in the dataset. This shiny app, called PeptidoformViz, can be freely downloaded from GitHub (statOmics/PeptidoformViz) via RStudio and enables the user to access powerful visualisation tools from ggplot and plotly without having to be able to program themselves. As input, the example dataset mentioned here can be easily uploaded and explored, or the user can upload their own dataset consisting of peptidoforms and their intensity values in one or more samples. Moreover, different pre-processing steps have been implemented such as normalisation techniques and logarithmic transformation. Afterwards the user has the option to download the processed dataset as well as the line plots and boxplots that were generated in the app. Because of the nature of shiny apps and how they are developed, it is easy to add functionalities later on. In the future, we intend to expand the app with advanced statistical analyses such as single PTM level quantification.

description: This review explains the relationship between density functional theory and strongly correlated models using the simplest possible example, the two-site Hubbard model. The relationship to traditional quantum chemistry is included. Even in this elementary example, where the exact ground-state energy and site occupations can be found analytically, there is much to be explained in terms of the underlying logic and aims of Density Functional Theory. Although the usual solution is analytic, the density functional is given only implicitly. We overcome this difficulty using the Levy-Lieb construction to create a parametrization of the exact function with negligible errors. The symmetric case is most commonly studied, but we find a rich variation in behavior by including asymmetry, as strong correlation physics vies with charge-transfer effects. We explore the behavior of the gap and the many-body Green's function, demonstrating the `failure' of the Kohn-Sham method to reproduce the fundamental gap. We perform benchmark calculations of the occupation and components of the KS potentials, the correlation kinetic energies, and the adiabatic connection. We test several approximate functionals (restricted and unrestricted Hartree-Fock and Bethe Ansatz Local Density Approximation) to show their successes and limitations. We also discuss and illustrate the concept of the derivative discontinuity. Useful appendices include analytic expressions for Density Functional energy components, several limits of the exact functional (weak- and strong-coupling, symmetric and asymmetric), the Kohn-Sham hopping energy functional for 3 sites, various adiabatic connection results, proofs of exact conditions for this model, and the origin of the Hubbard model from a minimal basis model for stretched H$_2$.
