description: Bright nearby stars are relevant targets for RV follow-up. The large angular separation between planets and their host stars will make it feasible to study these systems with future instrumentation for high contrast direct imaging such as the ANDES spectrograph for ELT, the HabEx or LUVOIR Nasa Missions, and the ESA LIFE mission. Among nearby stars, solar-type stars are of particular interest as they allow us to study the architecture and evolution of planetary systems born in similar environments to our own. HD 20794 is a G6 star known for hosting a multi-planetary system. According to the literature, the system is composed of 4 planets, with orbital periods spanning a range between 18 and 147 days and minimum masses between 2.4 and 4.8 Earth masses. The results were achieved by analyzing more than 10 years of HARPS observations. This star is one of the most stable targets of HARPS in the neighborhood of the Sun. We present here an updated analysis of this star.
 In our analysis, we used 4 years of observations made with the ESPRESSO spectrograph combined with the HARPS data reprocessed with the new YARARA pipeline. This analysis confirms the great stability of the star over long timescales with an RMS of 1.16 m/s over more than 17 years. We perform a state-of-the-art analysis of the RV data combined with the activity indicators to obtain the most refined model to date for the planetary and stellar components of the data.

description: Microfibrillated cellulose (MFC) was prepared by controlling the re-precipitation of cellulose prepared in the mixture form of NaOH/Urea solubilized microcrystalline cellulose (MCC) and starch. The cellulose re-precipitation was carried-out in an HCl bath, resulting in a MFC form having relatively lower crystallinity than MCC. The XRD pattern of MFC indicated the partially crystalline structure arising from the imperfect orientation of a cellulose chain obstructed by a starch molecule in the precipitation step. Interestingly, the MFC morphology exhibited a web-like structure with a diameter in the range of 10-20 nm. The water retention value of MFC was extraordinarily high due to its extremely small diameter having high surface area. Further, surface silanization of MFC with organosilane was carried out. Then, the modified MFC was melt-mixed with polypropylene (PP) matrix via a simple melt mixing technique. The morphology and crystallization of the PP/MFC composites were measured. The morphology of organosilane treated MFC exhibited agglomeration of 10 microns in diameter with layered structures arising from the packing of microfibrils. The FTIR spectra showed hydrophobic characteristics of treated MFC observed by the disappearance of original cellulose hydroxyl group and bound water. The crystallinity of treated MFC increased when compared to the untreated MFC, indicating that cellulose chains of unmodified MFC underwent re-orientation occurring in the modification step due to its high crystallinity characteristic. For the PP/MFC-composite containing MFC loading, faster crystallization and higher spherulite growth rate, in case of higher MFC loading, were observed. In addition, the spherulite size decreased with an increase in the crystallization temperature. However, the degree of crystallinity was fairly independent on the MFC-loading. Therefore it can be concluded that the addition of MFC might enable shorter cycle times, resulting in cheaper processing cost in a view point of polymer processing.

description: The Near-InfraRed Planet Searcher (NIRPS) is a new ultra-stable infrared (YJH) spectrograph installed at the ESO 3.6 meters telescope in La Silla. NIRPS is designed to search for rocky planets orbiting M-dwarf stars and it operates in synergy with HARPS spectrograph. It is built with the goal of reaching a precision of 1 m/s, the typical radial velocity signal expected by an Earth analogue around a cool M-dwarf. The main goals of the mission are to perform an high-precision RV survey of M-dwarfs, to measure mass and density of known transiting planetary candidates around M stars and to characterise planetary atmospheres via transmission spectroscopy.
On the origins of C IV absorption profile diversity in broad absorption line quasars

description: There is a large diversity in the C IV broad absorption line (BAL) profile among BAL quasars (BALQs). We quantify this diversity by exploring the distribution of the C IV BAL properties, FWHM, maximum depth of absorption and its velocity shift ($v_{\rm md}$), using the SDSS DR7 quasar catalogue. We find the following: (i) Although the median C IV BAL profile in the quasar rest-frame becomes broader and shallower as the UV continuum slope ($α_{\rm UV}$ at 1700-3000 A) gets bluer, the median individual profile in the absorber rest-frame remains identical, and is narrow (FWHM = 3500 km/s) and deep. Only 4 per cent of BALs have FWHM > 10,000 km/s. (ii) As the He II emission equivalent-width (EW) decreases, the distributions of FWHM and $v_{\rm md}$ extend to larger values, and the median maximum depth increases. These trends are consistent with theoretical models in which softer ionizing continua reduce overionization, and allow radiative acceleration of faster BAL outflows. (iii) As $α_{\rm UV}$ becomes bluer, the distribution of $v_{\rm md}$ extends to larger values. This trend may imply faster outflows at higher latitudes above the accretion disc plane. (iv) For non-BALQs, the C IV emission line decreases with decreasing He II EW, and becomes more asymmetric and blueshifted. This suggests an increasing relative contribution of emission from the BAL outflow to the C IV emission line as the ionizing spectral energy distribution (SED) gets softer, which is consistent with the increasing fraction of BALQs as the ionizing SED gets softer.

description: This study explored the veil as norm among modern middle and upper-middle-class women, a class that historically had rejected the veil until recently. The study sought to identify the loci of the forces pushing the wearing of the veil. The study is based on the integration of historical analysis with qualitative methods and content analysis. Specifically this research is based on triangulated data from (a) detailed interviews conducted with 65 young Muslim Egyptian women during the summer of 2008, (b) content analysis of 70 sermons delivered by four of the most influential preachers today, and (c) a survey of the history of the veil in Egypt. Findings showed that the veil has become a unique instrument of power employed by several actors at three new and interrelated arenas of struggle. At the social level, women are using the veil to redefine their roles in society. At the political level, they are using various forms of the veil to declare full or partial alliance with counter-hegemonic forces challenging the state’s moral authority and the state's political liberalization policies that have targeted women. At the global arena of power, women are engaged in a solidarity movement against the West and the forces of globalization. All these tension zones are influenced by new patterns of immigration in the Arab world and by new forms of intraregional globalization fostered by a newly emerging Arab satellite industry.This study was the beginning of research that should continue to investigate through the utilization of novel and more focused integrated methods this particular phenomenon. The struggle to remove the bonds of the West, in particular, invites future research to dissect the many aspects of interregional and intraregional globalization and their impact on religious identities across the world. This research also suggested that the attitudes towards the veil, women, the state, and the West are in a state of flux, requiring the use of novel identity barometers to assess the direction, magnitude, and implications of these changes on the relationships between the West and the Muslim world.

description: Despite advances in the pathophysiology of Chronic Obstructive Pulmonary Disease (COPD), there is a distinct lack of biochemical markers to aid clinical management. Microvesicles (MVs) have been implicated in the pathophysiology of inflammatory diseases including COPD but their association to COPD disease severity remains unknown. We analysed different MV populations in plasma and bronchoalveolar lavage fluid (BALF) taken from sixty-two patients with mild to very severe COPD (51% male; mean age: 65.9 years). These patients underwent comprehensive clinical evaluation (symptom scores, lung function, exercise testing) and the capacity of MVs to be clinical markers of disease severity was assessed. We successfully identified various MV subtype populations within BALF (leukocyte, PMN (polymorphonuclear leukocyte i.e. neutrophil), monocyte, epithelial and platelet MVs) and plasma (leukocyte, PMN, monocyte and endothelial MVs), and compared each MV population to disease severity. BALF neutrophil MVs were the only population to significantly correlate with the clinical evaluation scores including FEV1, mMRC dyspnoea score, 6-minute walk test, hyperinflation and gas transfer. BALF neutrophil MVs, but not neutrophil cell numbers, also strongly correlated with BODE index. We have undertaken, for the first time, a comprehensive evaluation of MV profiles within BALF/plasma of COPD patients. We demonstrate that BALF levels of neutrophil-derived MVs are unique in correlating with a number of key functional and clinically-relevant disease severity indices. Our results show the exciting potential of BALF neutrophil MVs for a COPD biomarker that tightly links, for the first time, a key pathophysiological mechanism of COPD (intra-alveolar neutrophil activation) with clinical severity/outcome.

description: In the field of interacting electron systems the Mott metal-to-insulator (MI) transition represents one of the pivotal issues. The role played by lattice degrees of freedom for the Mott MI transition and the Mott criticality in a variety of materials are current topics under debate. In this context, molecular conductors of the $κ$-(BEDT-TTF)$_2$X type constitute a class of materials for unraveling several aspects of the Mott physics. In this review, we present a synopsis of literature results with focus on recent expansivity measurements probing the Mott MI transition in this class of materials. Progress in the description of the Mott critical behavior is also addressed.

Authoritarianism, Democratization, and Great Power Alliances: Implication of Regime Dependence for Democratic Reform in Spain and Poland.
Creators: name: Holmes, Joseph Ingram
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: This thesis examines the effect of great power alliances on democratization in the context of Cold War Europe. This is an important context, as the geopolitical realities of the Cold War hindered democratization in many parts of the world during this period. The support that the United States and the Soviet Union gave to authoritarian regimes in order to prevent the expansion of influence of their rival was a major cause of this. Here we here seek to explore the ramifications for democratic transition that alliance politics present. Practically we seek to illuminate the effect of in international relations on democratic change within authoritarian regimes. But this question is dependent on the degree to which regimes are beholden to foreign allies. Theories on democratic peace and the structure of international relations presuppose that regime type, the nature of politics within a country, affects external political relations.  A government operating through a political model at home that relies upon consensual rule is deemed to behave differently than a regime that relies upon some level of coercion in maintaining itself when dealing with other states. The state that is run democratically might be assumed to have smoother relationships with likeminded states and more complicated relationships with states that are run autocratically. Yet the question of the degree to which autocratic and democratic states can trust one another is an important one for the issues it raises about the utility of relationships with authoritarian regimes. Democratic governments have long built and sustained close alliances with autocratic governments. Such relationships have been justified in many ways, but most fundamentally it can be argued that it is impossible for a state’s interests with another state to be adequately resolved if the internal affairs of one is treated as an absolute stumbling block to relations with another. The spectrum of possibility through which states satisfy the pragmatic with the idealistic instinct in their relations with states with entirely different political models, whether democracies or dictatorships, is the gateway into what we investigate here.

description: Key kinetic parameters governing the partitioning of chlorine species in the Antarctic polar stratosphere were retrieved from 28 days of chlorine monoxide (ClO) microwave radiometer measurements made during the late winter/early spring of 2005 at Scott Base (77.85° S, 166.75° E). During day-time the loss of the ClO dimer chlorine peroxide (ClOOCl) occurs mainly by photolysis. Some time after sunrise, a photochemical equilibrium is established and the ClO/ClOOCl partitioning is determined by the ratio of the photolysis frequency, J, and the dimer formation rate, kf. The values of J and kf from laboratory studies remain uncertain to a considerable extent, and as a complement to these ongoing studies, the goal of this work is to provide a constraint on that uncertainty based on observations of ClO profiles in the Antarctic. First an optimal estimation technique was used to derive J/kf ratios for a range of Keq values. The optimal estimation forward model was a photochemical box model that takes J, kf, and Keq as inputs, together with a priori profiles of activated chlorine (ClOx = ClO+2×ClOOCl), profiles of ozone, temperature, and pressure. JPL06 kinetics are used as a priori in the optimal estimation and for all other chemistry in the forward model. Using the more recent JPL09 kinetics results in insignificant differences in the retrieved value of J/kf. A complementary approach was used to derive the optimal kinetic parameters; the full parameter space of J, kf, Keq and ClOx was sampled to find the minimum in differences between measured and modelled ClO profiles. Furthermore, values of Keq up to 2.0 times larger than recommended by JPL06 were explored to test the sensitivity of the J/kf ratio to changes in Keq. The results show that the retrieved J/kf ratios bracket the range of 1.23 to 1.97 times the J/kf value recommended by JPL06 over the range of Keq values considered. The retrieved J/kf ratios lie in the lower half of the large uncertainty range of J/kf recommended by JPL06 and towards the upper portion of the smaller uncertainty range recommended by JPL09.

description: A long standing puzzle regarding the disparity of local and long range CuO6 octahedral tilt correlations in the underdoped regime of La2-xBaxCuO4 is addressed by utilizing complementary neutron powder diffraction and inelastic neutron scattering (INS) approaches. Long-range and static CuO6 tilt order with orthogonally inequivalent Cu-O bonds in the CuO2 planes in the low temperature tetragonal (LTT) phase is succeeded on warming through the low-temperature transition by one with orthogonally equivalent bonds in the low temperature orthorhombic (LTO) phase. In contrast, the signatures of LTT-type tilts in the instantaneous local atomic structure persist on heating throughout the LTO crystallographic phase on the nanoscale, although becoming weaker as temperature increases. Analysis of the INS spectra for the x = 1/8 composition reveals the dynamic nature of the LTT-like tilt fluctuations within the LTO phase and their 3D character. The doping dependence of relevant structural parameters indicates that the magnitude of the Cu-O bond anisotropy has a maximum at x = 1/8 doping where bulk superconductivity is most strongly suppressed, suggesting that the structural anisotropy might be influenced by electron-phonon coupling and the particular stability of the stripe-ordered phase at this composition. The bond-length modulation that pins stripe order is found to be remarkably subtle, with no anomalous bond length disorder at low temperature, placing an upper limit on any in-plane Cu-O bondlength anisotropy. The results further reveal that although appreciable octahedral tilts persist through the high-temperature transition and into the high temperature tetragonal (HTT) phase, there is no significant preference between different tilt directions in the HTT regime.

description: Periodic radio bursts from very low mass stars and brown dwarfs simultaneously probe their magnetic and rotational properties. The brown dwarf 2MASSI J1047539+212423 (2M 1047+21) is currently the only T dwarf (T6.5) detected at radio wavelengths. Previous observations of this source with the Arecibo observatory revealed intermittent, 100%-polarized radio pulses similar to those detected from other brown dwarfs, but were unable to constrain a pulse periodicity; previous VLA observations detected quiescent emission a factor of ~100 times fainter than the Arecibo pulses but no additional events. Here we present 14 hours of Very Large Array observations of this object that reveal a series of pulses at ~6 GHz with highly variable profiles, showing that the pulsing behavior evolves on time scales that are both long and short compared to the rotation period. We measure a periodicity of ~1.77 hr and identify it with the rotation period. This is just the sixth rotation period measurement in a late T dwarf, and the first obtained in the radio. We detect a pulse at 10 GHz as well, suggesting that the magnetic field strength of 2M 1047+21 reaches at least 3.6 kG. Although this object is the coolest and most rapidly-rotating radio-detected brown dwarf to date, its properties appear continuous with those of other such objects, suggesting that the generation of strong magnetic fields and radio emission may continue to even cooler objects. Further studies of this kind will help to clarify the relationships between mass, age, rotation, and magnetic activity at and beyond the end of the main sequence, where both theories and observational data are currently scarce.

However, the evolutionary origination of complicated pharynx organs in advanced vertebrates is still largely unknown. Endostyle, an evolutionarily transitional pharyngeal organ exclusively existing in basal chordates provides an opportunity to reveal the origin of pharyngeal organs. Here, by utilizing cutting-edged Stereo-seq and single-cell RNA-seq, we innovatively constructed the first single-cell resolved cell atlas in the endostyle of Styela clava, where the spatial location of Stereo-seq and high capture efficiency of single-cell RNA-seq complement each other.
An Investigation into the Initiation and Propagation of Discharge Channels in Polymeric Insulation

description: A test sample incorporating a divergent field electrode arrangement has been developed for the evaluation of the resistance of polymeric materials to discharge channel initiation and propagation. The sample is an injection moulded disc containing a conical pointed recess (between 3 and 5um radius) which is subsequently metallised to form a point electrode. The initiation and growth of discharges in polyethylene samples have been monitored using a tuned circuit discharge detector and it is shown that: 1) provided the injection moulding conditions are carefully controlled, reproducible results are obtained when 50Hz is applied at 20°C, 2) the presence of small quantities of certain aromatic hydrocarbons and antioxidants affects the voltage necessary to initiate discharges, and the subsequent growth of discharge channels. 3) with negative 1/50us impulses, applied to the point, the breakdown voltage at 20°C is double the value with the opposite polarity. With several positive impulses of increasing amplitude the b.d.v. is greater than with a single positive pulse, but there was no significant reduction after a preceding negative impulse.

description: Twisted coronal loops should be ubiquitous in the solar corona. Twisted magnetic fields contain excess magnetic energy, which can be released during magnetic reconnection, causing solar flares. The aim of this work is to investigate magnetic reconnection, and particle acceleration and transport in kink-unstable twisted coronal loops, with a focus on the effects of resistivity, loop geometry and atmospheric stratification. Another aim is to perform forward-modelling of bremsstrahlung emission and determine the structure of hard X-ray sources. We use a combination of magnetohydrodynamic (MHD) and test-particle methods. First, the evolution of the kinking coronal loop is considered using resistive MHD model, incorporating atmospheric stratification and loop curvature. Then, the obtained electric and magnetic fields and density distributions are used to calculate electron and proton trajectories using a guiding-centre approximation, taking into account Coulomb collisions. It is shown that electric fields in twisted coronal loops can effectively accelerate protons and electrons to energies up to 10 MeV. High-energy particles have hard, nearly power-law energy spectra. The volume occupied by high-energy particles demonstrates radial expansion, which results in the expansion of the visible hard X-ray loop and a gradual increase in hard X-ray footpoint area. Synthesised hard X-ray emission reveals strong footpoint sources and the extended coronal source, whose intensity strongly depends on the coronal loop density.

description: Because habitat loss is the primary threat to most species listed under the US Endangered Species Act (ESA), the requirement to designate critical habitat under the ESA intuitively appeals to many conservationists. As the ESA approaches 50 years of implementation, however, it has become clear to many people that species recovery does not always require or even benefit from critical habitat. In some situations, critical habitat may even undercut incentives for private landowners to help recover species. In other situations, however, critical habitat offers indirect or direct benefits to conservation. What are the situations when designation benefits recovery, has no effect on recovery, and undercuts recovery? And how should the US Fish and Wildlife Service and National Marine Fisheries Service decide whether and how to designate critical habitat in each of those situations, especially on private lands, after considering the benefits and costs of designation for recovery? This paper offers perspectives on these questions and a worksheet that the agencies can use to methodically evaluate the advantages and disadvantages of designating an area as critical habitat.

description: Abstract. The paper discusses the application of Natural Language Processing (NLP) techniques in the context of semantic annotation of classical art text via rule-based Information Extraction (IE) techniques combined with ontological and domain vocabulary input. The CASIE (Classical Art Semantics Information Extraction) was a pilot collaborative project between the Hypermedia Research
 Unit (University of South Wales) and the Beazley Archive (Oxford University), which aims to automatically extract information about cultural objects from classical art scholarly texts and represent this information in terms of the ISO metadata standard for cultural heritage, the International Council of Museum’s CIDOC Conceptual Reference Model (CRM). In total 12 documents (fascicules
 – high quality catalogues) were processed, originating from the Corpus Vasorum Antiquorum (CVA) collection containing over 350 high quality catalogues of mostly ancient Greek painted pottery, illustrating more than 100,000 vases. The extracted information was expressed in interoperable RDF graphs consistent with the CLAROS project format. The role of CIDOC-CRM is central for enabling semantic interoperability across the range of datasets that contribute to CLAROS. The CASIE pilot enabled a complementary exploitation of terminological and ontological resources via rule-based information extraction techniques, delivering semantic annotation with respect to the CRM in the broader field of digital humanities.

description: The μ-phase is a common precipitation phase in superalloys and it exists in a wide composition and temperature range. As such, we study the influences of composition and temperature on its plasticity by micropillar compression tests and transmission electron microscopy. The micropillars of the μ-Co7Nb6 phase deform plastically by basal slip at either room temperature or 600 oC. At room temperature, the Co-49Nb and Co-52Nb micropillars show high yield stresses and an abrupt large strain burst at the onset of yielding regardless of orientation, whereas the Co-54Nb micropillars oriented for basal slip yield at much lower stresses and show intermittent small strain bursts during plastic deformation. While the Co-49Nb micropillars deform by full dislocation slip on the basal plane at room temperature, the Co-54Nb micropillars deform by partial dislocation slip on the basal plane. At 600 oC, the Co-49Nb micropillars oriented for basal slip show stable and continuous plasticity and their critical resolved shear stress decreases dramatically. The plastic deformation of the Co-49Nb micropillars occurs via partial dislocation slip on the basal plane at 600 oC. Based on the geometric γ-surfaces for all potential basal slip planes, we explore where and why the glide of full and partial dislocations on the basal plane occurs in the μ-Co7Nb6 phase.

description: We present high spectral resolution (~3 km/s) observations of the nu_2 ro-vibrational band of H2O in the 6.086--6.135 micron range toward the massive protostar AFGL 2591 using the Echelon-Cross-Echelle Spectrograph (EXES) on the Stratospheric Observatory for Infrared Astronomy (SOFIA). Ten absorption features are detected in total, with seven caused by transitions in the nu_2 band of H2O, two by transitions in the first vibrationally excited nu_2 band of H2O, and one by a transition in the nu_2 band of H2{18}O. Among the detected transitions is the nu_2 1(1,1)--0(0,0) line which probes the lowest lying rotational level of para-H2O. The stronger transitions appear to be optically thick, but reach maximum absorption at a depth of about 25%, suggesting that the background source is only partially covered by the absorbing gas, or that the absorption arises within the 6 micron emitting photosphere. Assuming a covering fraction of 25%, the H2O column density and rotational temperature that best fit the observed absorption lines are N(H2O)=(1.3+-0.3)*10^{19} cm^{-2} and T=640+-80 K.

Anthropomorphic Human Carotid Ultrasound Phantom

description: Vascular hemodynamics and plaque composition are indicators of stroke risk. Previous work indicates that multi-angle Plane Wave (PW) implementation of Acoustic Radiation Force Impulse (ARFI), Log Variance of Acceleration (log(VoA)), and 2-D Vector Doppler (VD) imaging can detect plaque structure and composition. Additional preceding work used Fluid-Structure Interaction (FSI) modeling to simulate blood fluid dynamics to estimate Wall Shear Stress (WSS) for plaque characterization and rupture risk evaluation. Anthropomorphic tissue-mimicking phantoms are constructed to recapitulate WSS measurements in complex human carotid arteries with pronounced plaques. Ultrasound experiments using duel PW Log(VoA) and 2D VD sequences under steady-state flow conditions are compared to the analogous FSI model simulations. The results suggest that thin-walled and wall-less anthropomorphic flow phantoms can be constructed to resemble the FSI model in physical geometry and WSS vessel profiles. These flow phantoms are currently limited to construction challenges.

description: This deliverable reports on the delivered data management (DM) and data stewardship (DS) training events across ELIXIR Nodes in the period from January 1, 2022 to June 30, 2023 as well as cumulative report of DM and DS training events from the start of the project until June 30, 2023. In the observed period from January 1, 2022 until June 30, 2023 there were 73 additional DM training events: 51 events in 2022 and 22 events in 2023, organised by 15 Nodes, with 1713 participants. The most covered training gap was DM Plans (33 training events), followed by Reproducibility (25 training events) and FAIR (21 training events). Cumulatively there were 149 courses organised by 18 Nodes with more than 4500 participants.
 The organisation of training events was carried out in collaboration with three other WP2 Tasks: Identification of training needs (T2.1), Developing materials (T2.2) and Outreach (T2.4). The training events encompass both reruns of existing courses (including updated courses), as well as the delivery of new courses based on the new training materials developed in Task 2.2. The report is based on the continuously updated ELIXIR-CONVERGE roadmap for DM training and capacity building, which was initially provided in D2.1. A summary of key data on the training events in the observed periods covered by this Deliverable is presented in the Results section. The collected data show how the delivery of training events improved from the start of ELIXIR-CONVERGE to better match training gaps and needs in the ELIXIR community and wider in the European research area. The data and metadata about training events were collected in the Training Inventory spreadsheet, including the information on training gaps covered by each event. The Training Inventory spreadsheet proved as a useful tool for collecting information and will continue to serve as an useful resource for training data collection beyond the ELIXIR-CONVERGE project until the more user friendly and system solution will be prepared as a part of ELIXIR Training Lifecycle. The collected information was helpful for shaping and will help to improve RDM Trainer Network (former Community of Practice of DM/DS trainers) activities as planned in the ELIXIR Training Platform 2024-2028 Programme. The RDM Trainer Network also includes national Nodes in order to accelerate the alignment of ELIXIR training efforts with national activities and to ensure sustainability of training.

description: This work is concerned to study the bouncing nature of the universe for an isotropic configuration of fluid $\mathcal{T}_{αβ}$ and Friedmann-Lemaître-Robertson-Walker metric scheme. This work is carried out under the novel $f(\mathcal{G},\mathcal{T}_{αβ} \mathcal{T}^{αβ})$ gravitation by assuming a specific model i.e, $f(\mathcal{G},\mathcal{T}^2)=\mathcal{G}+α\mathcal{G}^2+2λ\mathcal{T}^2$ with $α$ and $λ$ are constants, serving as free parameters. {The terms $\mathcal{G}$ and $\mathcal{T}^2$ served as an Gauss-Bonnet invariant and square of the energy-momentum trace term as an inclusion in the gravitational action respectively, and is proportional to $\mathcal{T}^2=\mathcal{T}_{αβ} \mathcal{T}^{αβ}$.} A specific functional form of the Hubble parameter is taken to provide the evolution of cosmographic parameters. A well known equation of state parameter, $ω(t)=-\frac{k \log (t+ε)}{t}-1$ is used to represent the dynamical behavior of energy density, matter pressure and energy conditions. A detailed graphical analysis is also provided to review the bounce. Furthermore, all free parameters are set in a way, to make the supposed Hubble parameter act as the bouncing solution and ensure the viability of energy conditions. Conclusively, all necessary conditions for a bouncing model are checked.

description: Digital technologies facilitate the coordination of energy sales between consumers in vastly different ways than in the past. In these new transactive energy systems, digital devices like smart energy meters are programmed to buy and sell electricity from other households or traditional electricity providers. This is a dramatically different system than the current utility-based model where there is one supplier of electricity that all consumers purchase from. This research first examines the potential for digital technologies to provide new services to consumers. The paper then discusses how current utility regulations prevent the use and growth of digital technologies. Finally, it suggests policy changes to encourage the use of digital energy technologies. Moving toward a transactive energy system on a broader scale will take time. The authors propose several policy changes that could clear the way for continued innovation in decentralized energy markets. They include allowing electricity rates to vary dynamically over the day based on overall demand, directing utilities away from cost-based rate setting and towards a consumer protection model that provides information on electricity suppliers, and implementing performance-based rates that compensate utilities for providing the electrical grid infrastructure that households use to buy and sell electricity. The authors find that these changes would allow innovative digital technologies to improve people’s lives by making electricity more affordable and cleaner.

description: This habilitation thesis centres on linearisation of vector-valued functions which means that vector-valued functions are represented by continuous linear operators. The first question we face is which vector-valued functions may be represented by continuous linear operators where vector-valued means that the functions have values in a locally convex Hausdorff space $E$. We study this problem in the framework of $\varepsilon$-products and give sufficient conditions when a space of $E$-valued functions coincides (up to an isomorphism) with the $\varepsilon$-product of a corresponding space of scalar-valued functions and the codomain $E$. We apply our linearisation results to lift results that are known for the scalar-valued case to the vector-valued case. We transfer the solvability of a linear partial differential equation in certain function spaces from the scalar-valued case to the vector-valued case, which also gives an affirmative answer to the question of (continuous, smooth, holomorphic, distributional, etc.) parameter dependence of solutions in the scalar-valued case. Further, we give a unified approach to handle the problem of extending vector-valued functions via the existence of weak extensions under the constraint of preserving the properties, like holomorphy, of the scalar-valued extensions. Our approach also covers weak-strong principles. In particular, we study weak-strong principles for continuously partially differentiable functions of finite order and improve the well-known weak-strong principles of Grothendieck and Schwartz. We use our results to derive Blaschke's convergence theorem for several spaces of vector-valued functions and Wolff's theorem for the description of dual spaces of several function spaces of scalar-valued functions. Moreover, we transfer known series expansions and sequence space representations from scalar-valued to vector-valued functions.
