description: Heat and power have become the most indispensable resources. However, the traditional ways of generating power and heat are inefficient and cause high pollution; a CHP (Combined Heat and Power) unit can solve these problems well. In recent years, more attention has been paid to energy conservation and environmental protection, and Combined Heat and Power Economic Emission Dispatch (CHPEED) has become an important multi-objective optimization problem. In this paper, an Indicator & crowding Distance-based Evolutionary Algorithm (IDBEA) is put forward for handling this non-convex and non-linear problem. With consideration of the valve-point effects and power transmission loss, IDBEA is tested on three standard test systems with different types, including four units, five units and seven units. In the experiment, IDBEA is compared with several evolutionary algorithms, the simulation results demonstrate that IDBEA has strong stability and superiority, while the solutions show better convergence and diversity than several typical algorithms.

description: An optimal filter for Poisson observations is developed as a variant of the traditional Kalman filter. Poisson distributions are characteristic of infectious diseases, which model the number of patients recorded as presenting each day to a health care system. We develop both a linear and nonlinear (extended) filter. The methods are applied to a case study of neonatal sepsis and postinfectious hydrocephalus in Africa, using parameters estimated from publicly available data. Our approach is applicable to a broad range of disease dynamics, including both noncommunicable and the inherent nonlinearities of communicable infectious diseases and epidemics such as from COVID-19.

description: In today’s modern world tall structures like high-rise buildings, skyscrapers, towers are needed to be
safe and stable. To provide stability to tall structures when shear wall is not enough to provide lateral support,
therefore wall belt supported system is the one of the best technique to increase the stability of the same. Wall
belt supported system is provided at the periphery of the tall structures throughout its height to increase the
stability. The current work shows the literature survey of various researchers who have been contributing in this
field. Conclusions with the outline of the proposed work are provided at the end of the work.

description: Most natural and artificial materials have crystalline structures from which abundant topological phases emerge [1-6]. The bulk-edge correspondence, widely-adopted in experiments to determine the band topology from edge properties, however, becomes inadequate in discerning various topological crystalline phases [7-17], leading to great challenges in the experimental classification of the large family of topological crystalline materials [4-6]. Theories predict that disclinations, ubiquitous crystallographic defects, provide an effective probe of crystalline topology beyond edges [18-21], which, however, has not yet been confirmed in experiments. Here, we report the experimental discovery of the bulk-disclination correspondence which is manifested as the fractional spectral charge and robust bound states at the disclinations. The fractional disclination charge originates from the symmetry-protected bulk charge patterns---a fundamental property of many topological crystalline insulators (TCIs). Meanwhile, the robust bound states at disclinations emerge as a secondary, but directly observable property of TCIs. Using reconfigurable photonic crystals as photonic TCIs with higher-order topology, we observe those hallmark features via pump-probe and near-field detection measurements. Both the fractional charge and the localized states are demonstrated to emerge at the disclination in the TCI phase but vanish in the trivial phase. The experimental discovery of bulk-disclination correspondence unveils a novel fundamental phenomenon and a new paradigm for exploring topological materials.

description: The reduction of the overall budget of the project leads to the cost effective one and there should be
such criteria of reduction of the cost in different manner. To make economic structure without losing the stiffness
criteria, the work has been performed in two stages. The former one is building with single shear wall core and
the latter one is building with dual core shear wall; the entire work has performed with four different phases. In
first phase total 5 buildings that are modeled with different openings in single core types shear wall and then
second phase performs the analysis procedures of the same. The third phases have total 6 buildings that are
modeled with different openings in dual core types shear wall and then fourth phase performs the analysis
procedures of the same. The result analysis has been performed and then conclusions are drawn. Building with
25% opening area in single core type shear wall and 50% opening area in dual core type shear wall performs
well to reduce the cost of the project.

description: Temperature time traces are obtained in turbulent thermal convection at high Rayleigh numbers. Measurements are made in the midplane of the apparatus, near the sidewall but outside the boundary layer. A telegraph approximation for temperature traces is generated by setting the fluctuation amplitude to 1 or 0 depending on whether or not it exceeds the mean value. Unlike the standard diagnostics of intermittency, the telegraph approximation allows one to distinguish the tendency of events to cluster ("clusterization") from their large-scale variability in amplitude. A qualitative conclusion is that amplitude intermittency might mitigate clusterization effects.
Usi storiografici di uno schema retorico: la disputatio in utramque partem

description: L’idea che l’abilità nell’arte della parola e del ragionamento si sviluppasse ​​al meglio se allenata alla prassi del contraddittorio era profondamente radicata nel mondo romano, dove la capacità dialettica di discutere entrambi i lati di una questione (in utramque partem disserere) rappresentava un obiettivo fondamentale del percorso di formazione dell’élite. In modo interessante, questa tecnica non è stata utilizzata fruttuosamente solo in ambito scolastico, ma anche dagli storici antichi, che nella ricostruzione di dibattiti politici si sono sovente serviti proprio di coppie di discorsi contrapposti. Il saggio si occuperà dunque degli impieghi della cosiddetta disputatio in utramque partem nella storiografia latina: esaminando le occorrenze dello schema retorico in Sallustio, Livio e Tacito, si cercherà di evidenziare come la rilevanza di questo espediente andasse ben oltre il piano letterario, recando al contrario risvolti di assoluto interesse sotto il profilo epistemologico, etico e pedagogico.

description: Children were often near the center of public debates about legal marriage recognition for same-sex couples. Obergefell v. Hodges (2015), the case that resulted in legal same-sex marriage recognition, stressed the importance of these children as one of many factors compelling the opinion. Estimates indicated same-sex couples were raising 200,000 children in the United States. Children raised by same-sex couples may be politically socialized in distinct ways compared to children of different-sex couples because lesbians, gay men, and bisexuals tend to hold distinct and progressive political viewpoints on a wide variety of issues. What are the political attitudes of people with same-sex parents? In this exploratory study, we analyze a large, representative survey of first-year college students across the United States; we find few differences between people with same-sex and different-sex parents, and some of those differences may be attributable to households and respondent characteristics. When on the rare occasion a difference exists, we find that people with same-sex female parents are more progressive, but people with same-sex male parents are more conservative. Gender differences also emerged, with some distinctive patterns between males with same-sex parents and females with same-sex parents.

We observed carefully selected regions near 9 clusters, consistent with magnification factors generally greater than 10 for the redshift range 4.5L) proportional to L^-1 over 10^41 to 10^42.5 erg/s. When combined with the results of other surveys, limited at higher luminosities, our results suggest evidence for the suppression of star formation in low-mass halos, as predicted in popular models of galaxy formation.

title: The role of the PI3K/AKT signalling pathway during avian infectious bronchitis infection
Creators: name: Batra, A
Publisher: name: University of Liverpool Repository
Year: 2017

description: Infectious bronchitis is a highly contagious respiratory disease that results in reduced egg production and can be fatal in young birds. It has recently been identified as the most economically detrimental disease to the poultry industry. It is caused by the gammacoronavirus infectious bronchitis virus (IBV), which is endemic in most countries worldwide. All viruses modulate cellular processes to establish themselves within the cell. The cellular PI3K/AKT signalling pathway is often modified by viruses and plays a crucial role in the regulation of many cellular processes. In this project the activation of the PI3K/AKT signalling pathway and downstream processes such as apoptosis, translation and macropinocytosis were investigated during IBV infection. Techniques such as western blotting, immunofluorescence, flow cytometry and protein expression were used to determine the effect of IBV infection on modulation of the signalling pathway, as well as the downstream cellular effects of the modulation. This study demonstrates that IBV requires an active PI3K/AKT pathway for efficient replication, and that infection with IBV induces phosphorylation of AKT in a PI3K-dependent manner in mammalian and avian cells. This activation occurs late during infection in mammalian cells. However, in avian cells activation occurs in a biphasic manner at both an early and late time point during infection. To summarise the findings, a model is presented to describe the role of the PI3K/AKT signalling pathway during IBV infection. This study highlights the importance of the PI3K/AKT signalling pathway during IBV infection and may be applied to other human and livestock coronaviruses for development of therapeutics or novel vaccines.

Created with federal funding as part of the American Women's History Initiative (AWHI), the exhibition commemorates the centennial of women's suffrage. To put a fresh spin on this anniversary and draw attention to larger, intertwining issues of gender and politics in the United States, the exhibition team chose to explore the history of girlhood and girls as political actors as the focus of the show. Drawing on the rich, interdisciplinary literature of girlhood studies and inspired by zines as a form of identity creation and political self-expression, the show aims to create a public history of girlhood that unveils the public lives of girls in the past and showcases the many ways in which they, even without the vote or formal political power, have had a political voice in American history. The exhibition is open at the NMAH from October 2020 to January 2023, and will travel with the Smithsonian Institution Traveling Exhibition Service through 2026.

description: We discuss the contribution of proton photoproduction interactions on the isotropic infrared/optical background to the cosmic neutrino fluxes. This contribution has a strong dependence on the proton injection energy spectrum, and is essential at high redshifts. It is thus closely correlated with the cosmological evolution of the ultra high energy proton sources and of the inrared background itself. These interactions may also contribute to the source fluxes of neutrinos if the proton sources are located in regious of high infrared emission and magnetic fields.

description: This paper examines a fifth-century B.C. obscure ceremony: the libations to Dionysus poured by the ten generals during the Athenian Dionysia in the theatre – a practice attested only by Plutarch’s Life of Cimon. The investigation here conducted firstly contextualises the libations as a religious ritual and, secondly, analyses its performers from a historico-political perspective. While highlighting the problematics for assessing and interpreting the libations as an unambiguous event, the paper investigates: (a) what the performers did during a libation; (b) who were the ordinary officers of the libations; and (c) to what extent democratic ideology was involved during the ritual.

description: Magmatic volatiles can be considered as the surface fingerprint of active volcanic systems, both during periods of quiescent and eruptive volcanic activity. The spatial variability of gas emissions at Earths surface is a proxy for structural discontinuities in the subsurface of volcanic systems. We conducted extensive and regular spaced soil gas surveys within the Los Humeros geothermal field to improve the understanding of the structural control on fluid flow. Surveys at different scales were performed with the aim to identify areas of increased gas emissions on reservoir scale, their relation to unknown/knows volcano-tectonic structures on fault scale favoring fluid flow, and determine the origin of gas emissions. Herein, we show results from a carbon dioxide efflux scouting survey, which was performed across the main geothermal production zone together with soil temperature measurements. We identified five areas with increased carbon dioxide emissions, where further sampling was performed with denser sampling grids to understand the fault zone architecture and local variations in gas emissions. We show that a systematic sampling approach on reservoir scale is necessary for the identification and assessment of major permeable fault segments. The combined processing of CO2 efflux and carbon/helium isotopes facilitated the detection of permeable structural segments with a connection to the deep, high-temperature geothermal reservoir, also in areas with low to intermediate carbon dioxide emissions. The results of this study complement existing geophysical datasets and define further promising areas for future exploration activities in the north- and southwestern sector of the production field.

Since the matrix unfoldings of three qubits are related to their reduced density matrices, HOSVD simultaneously diagonalizes the one-body reduced density matrices of three qubits. From the all-orthogonality conditions of HOSVD, we computed the special states of three qubits. Furthermore, we showed that it is possible to construct a polytope that encapsulates all the special states of three qubits by LU operations with HOSVD.

description: The exceptionally favorable close approach of Jupiter-family comet 46P/Wirtanen in 2018 December enabled characterization of its primary volatile composition with exceptionally high spatial resolution and sensitivities using the iSHELL spectrograph at the NASA Infrared Telescope Facility on Maunakea, HI. We sampled emissions from H2O, HCN, C2H2, NH3, C2H6, and CH3OH on UT 2018 December 21 using two instrumental settings that spanned the 2.9–3.6 μm spectral region. We also obtained a sensitive 3σ upper limit for H2CO and for the rarely studied molecule HC3N. We report rotational temperatures, production rates, and mixing ratios (relative to H2O as well as to C2H6). We place our results in context by comparing them with other comets observed at near-IR wavelengths. We also compare our results with those obtained using the NIRSPEC-2 spectrograph on Keck II on UT December 17 and 18 and with results obtained from iSHELL on other dates during the same apparition. Within 1–2σ uncertainty, production rates obtained for all molecules in this work were consistent with those obtained using NIRSPEC-2 except H2O, indicating low-level variability on a timescale of days. Mixing ratios with respect to H2O in 46P/Wirtanen were consistent with corresponding values from NIRSPEC-2 within the uncertainty with the exception of CH3OH, which yielded a higher ratio on December 21. Our measurements afforded a high temporal resolution that spanned ∼2/3 of the rotational period of 46P/Wirtanen, enabling us to test short-term variability in the production rates of H2O and HCN due to rotational effects. Both H2O and HCN production rates showed similar temporal variability, resulting in nearly constant HCN/H2O.

Désigner chez les orateurs attiques les discours des ambassadeurs « ratés »: vocabulaire et figures

description: Abstract in English: In this paper, I examine the vocabulary which the Attic orators use in order to present the speeches of the ambassadors who are criticized for obstructing the truth and the interests of an embassy or a state. With few exceptions, there is a lack of firsthand written records of those who took part in the legations. In order to determine whether they really deserve the criticism, it is necessary to take into consideration several factors that intervene in the use of this particular vocabulary: the historical context and the interests at stake during an embassy, as well as the point of view of those who criticize them. It turns out that their criticism does not necessarily mean that the ambassadors did not fulfill the mission entrusted to them. On the contrary, the political conditions and the perspective adopted by the Attic orators interact with each other and allow to paint a negative portrait of the ambassadors that serve specific rhetorical or political goals. Résumé en français: La présente étude examine le vocabulaire qu’utilisent les orateurs attiques pour présenter les paroles des ambassadeurs qui ne sont pas considérées comme conformes à la vérité et aux intérêts d’une ambassade ou d’un État. À quelques exceptions près, leurs discours ne nous sont pas directement transmis et, pour pouvoir déterminer si les ambassadeurs méritent réellement les qualificatifs qu’on leur attribue, il faut examiner les différents facteurs qui interviennent dans l’usage du vocabulaire en question : les circonstances historiques, les enjeux de l’ambassade, le parti pris de ceux qui critiquent leur action. Il s’avère que le portrait péjoratif qui en découle ne signifie pas nécessairement que les ambassadeurs n’ont pas rempli la mission qui leur a été confiée, mais que les conditions politiques et la perspective adoptée par les orateurs interagissent entre elles, en permettant d’esquisser une image négative propre à leurs buts rhétoriques ou politiques.

We study the properties of the phase transition focusing on the possible cosmological signatures it can provide. Interestingly the model is well under perturbative control only when the mass of the lightest field - the dilaton/scalon is much lighter than the rest of the fields and the phase transition proceeds slowly leading to strong signals in the stochastic gravitational wave spectrum.

BCE, recording the leases of the mines by the Athenian polity to individuals (the poletae record), as mental maps. The research aim is threefold: first, to reconstruct a flexible set of abstract mental maps, beyond a defined geometric space, in order to explore the network of spatial relationships defined in the epigraphical record and the social and economic meanings involved; second, to develop a methodology for the production of an “intermediate” map, spatially and geometrically correct, which transforms the mental map into an intra-referential map; third, final goal is to proceed to a reconstruction (insofar it is possible) of the landscape and the topographical layout of the area as in the 4th cent. BCE.

description: Rapidly applying the effects of detector response to physics objects (e.g. electrons, muons, showers of particles) is essential in high energy physics. Currently available tools for the transformation from truth-level physics objects to reconstructed detector-level physics objects involve manually defining resolution functions. These resolution functions are typically derived in bins of variables that are correlated with the resolution (e.g. pseudorapidity and transverse momentum). This process is time consuming, requires manual updates when detector conditions change, and can miss important correlations. Machine learning offers a way to automate the process of building these truth-to-reconstructed object transformations and can capture complex correlation for any given set of input variables. Such machine learning algorithms, with sufficient optimization, could have a wide range of applications: improving phenomenological studies by using a better detector representation, allowing for more efficient production of Geant4 simulation by only simulating events within an interesting part of phase space, and studies on future experimental sensitivity to new physics.

Publisher: name: The University of British Columbia

description: The purpose of this directed study was to determine the feasibility of operating a compost facility on an existing 12m x 24m concrete pad located at the UBC farm. Composting methods and processes were examined to maximize the productivity of the space available and to promote biological conditions for the production of safe, high quality finished compost. Once it was determined that a safe end product could be produced using waste generated at UBC, economic feasibility was assessed. An approximate budget for an on-farm compost facility is included. Outlined in this paper are the specific regulations that pertain to the operation of an industrial compost facility on the UBC farm, and the criteria that must be met in order to produce the highest quality compost using materials generated on the UBC campus. This report also gives specific suggestions and methods as to how these regulations can be followed and criteria met.

description: Detailed models of alpha Cen A and B based on new seismological data for alpha Cen B by Carrier & Bourban (2003) have been computed using the Geneva evolution code including atomic diffusion. Taking into account the numerous observational constraints now available for the alpha Cen system, we find a stellar model which is in good agreement with the astrometric, photometric, spectroscopic and asteroseismic data. The global parameters of the alpha Cen system are now firmly constrained to an age of t=6.52+-0.30 Gyr, an initial helium mass fraction Y_i=0.275+-0.010 and an initial metallicity (Z/X)_i=0.0434+-0.0020. Thanks to these numerous observational constraints, we confirm that the mixing-length parameter alpha of the B component is larger than the one of the A component, as already suggested by many authors (Noels et al. 1991, Fernandes & Neuforge 1995 and Guenther & Demarque 2000): alpha_B is about 8% larger than alpha_A (alpha_A=1.83+-0.10 and alpha_B=1.97+-0.10). Moreover, we show that asteroseismic measurements enable to determine the radii of both stars with a very high precision (errors smaller than 0.3%). The radii deduced from seismological data are compatible with the new interferometric results of Kervella et al. (2003) even if they are slightly larger than the interferometric radii (differences smaller than 1%).

title: Spatio-temporal evolution of interictal epileptic activity : a study with unaveraged multichannel MEG data in association with MRIs.
Creators: name: Bamidis, Panagiotis D.
Publisher: name: The Open University
Year: 1996

description: This thesis addresses issues relating to MEG modelling, analysis and interpretation of results. A source model employing current density distributions, namely Magnetic Field Tomography (MET), is used to obtain the MEG results.

The first issue of concern refers to the registration of MEG data with structural MR images in an attempt to improve the localisation capability of MEG/MET. Simulations testing some spatial and tem poral aspects of the reconstruction capability of MET are also provided. A novel way of conducting MET studies in depth is suggested and implemented: the iterative use of a source space designed to cover deep situated structures on either side of the brain.

The main bulk of this thesis is concerned with research into interictal epileptic activity as recorded by means of multichannel MEG system s and analysed using MET. The major aim is to investigate whether or not MET analysis of unaveraged MEG data (single epochs) is feasible in cases of pathophysiological signals and more specifically interictal signals from patients with epilepsy of a complex partial type. The investigation is undertaken against the "traditional" view of the impropriety and absurdity of using single epoch records in the MEG analysis due to noise dominance; we provide evidence that analysis of single, unaveraged epileptic spikes is actually feasible: we demonstrate spatio-temporal coherence in the MET results of the various single interictal events and show that activity extracted from the "averaged event" is made up of activity contributions which occur intermittently and at variable latencies. Our statements are drawn from the study of both superficial and deep activity.

description: We consider stochastically quantized self-interacting scalar fields as suitable models to generate dark energy in the universe. Second quantization effects lead to new and unexpected phenomena is the self interaction strength is strong. The stochastically quantized dynamics can degenerate to a chaotic dynamics conjugated to a Bernoulli shift in fictitious time, and the right amount of vacuum energy density can be generated without fine tuning. It is numerically observed that the scalar field dynamics distinguishes fundamental parameters such as the electroweak and strong coupling constants as corresponding to local minima in the dark energy landscape. Chaotic fields can offer possible solutions to the cosmological coincidence problem, as well as to the problem of uniqueness of vacua.

The Places of the Inscriptions: from Epigraphy to Digital Epigraphy

description: In the study and edition of ancient inscriptions, a non-secondary part is dedicated to the analysis and record of spatial, topographical, and geographic information relating to the places of discovery, original location, conservation of the inscribed artefacts, or the references to ancient places or communities occurring in the epigraphic texts. Attention toward the places of inscriptions has grown significantly as a result of the “digital turn” that has affected Ancient Geography and Topography, and it is in fact a very important component in Digital Epigraphy projects. The article reflects on these aspects by examining a series of concrete examples in the current DH landscape. Through the analysis of these cases, it is highlighted how the epigraphic databases adopt different models and tools for the digital representation of the places of the inscriptions, on the base of the different contexts or categories of inscriptions, or of specific research perspectives. In particular, tendency towards the adoption of a “GIS model” or, differently, of a “LOD gazetteer model” for the representation of places in epigraphic digital projects once again proposes the time-honoured theme of the study of inscriptions in their double nature as monuments and documents, as archaeological object and texts.

description: We perform hybrid-density functional calculations to investigate the charged defect formation energy of native point defects in $Mg_2 Si$, $Mg_2 Sn$, and their solid solutions. The band gap correction by hybrid-density functional is found to be critical to determine the charged defect density in these materials. For $Mg_2 Si$, $Mg$ interstitials are dominant and provide unintentional $n$-type conductivity. Additionally, as the $Mg$ vacancies can dominate in $Mg$-poor $Mg_2 Sn$, $p$-type conductivity is possible for $Mg_2 Sn$. However, the existence of low formation energy defects such as $Mg_{Sn}^{1+}$ and $I_{Mg}^{2+}$ in $Mg_2 Sn$ and their diffusion can cause severe charge compensation of hole carriers resulting in low $p$-type doping efficiency and thermal degradation. Our results indicate that, in addition to the extrinsic doping strategy, alloying of $Mg_2 Si$ with $Mg_2 Sn$ under $Mg$-poor conditions would be necessary to enhance the $p$-type conductivity with less charge compensation.
