Tephrostratigraphy and hominin paleoenvironments of the Hadar Formation, Afar Depression, Ethiopia
Creators: name: Campisano, Christopher James
Publisher: name: No Publisher Supplied
Year: 2007

description: The deposits of the Hadar Formation preserve a continuous record of hominin habitats and environmental change from ca. 3.45 Ma until a regional disconformity at ca. 2.9 Ma. At Hadar, strata below the disconformity are composed of fluvial sands and well-developed claystone paleosols associated with a large-scale meandering river system and several brief lacustrine intervals associated with westward transgressions of the lacustrine depocenter to the east. Detailed analysis of these deposits indicates a strong cyclicity in the fluvial system with regular intercalations of fully lacustrine, lake margin, or ephemeral floodplain lake facies. Following the disconformity, sediment preservation at Hadar is highly localized and represents a major change in depositional facies and character with strata composed primarily of cut-and-fill channel conglomerates and silt-dominated paleosols. A comprehensive tephrostratigraphic analysis of the Hadar Formation volcanics has identified at least 12 distinct vitric tephra preserved above the disconformity at Hadar until ca. 0.78 Ma. Surprisingly few of these tephra correlate to the early archaeology sites in the adjacent Gona region, which reflect the complex paleogeography of these deposits. New radiometric and paleomagnetic age estimates are in general agreement with previously published results, while previously undated tuffs help refine the chronological framework of the formation.Analysis of the Hadar faunal assemblages indicates that a range of habitats were available to Australopithecus afarensis through time and space including open and closed woodlands, gallery forests, edaphic grasslands, and shrublands. Some of the variation observed in these faunal communities can be explained by the spatial distribution of fauna across the landscape, as well as by the depositional environments with which they are associated. Although there is no clear directional trend observed in habitats through time, the faunal assemblages indicate slightly more xeric conditions beginning around 3.2 Ma with a distinct faunal turnover at 3.0 Ma. This shift may be related to changes in global climate patterns, particularly seasonality. Tests of association between A. afarensis and other taxa, as well as the spatial distribution of A. afarensis across the paleolandscape provide little evidence to suggest a habitat preference for the early hominin despite persisting throughout a half million years of environmental and climatic shifts recorded at Hadar.

description: Hi-C data provide population averaged estimates of three-dimensional chromatin contacts across cell types and states in bulk samples. Effective analysis of Hi-C data entails controlling for the potential confounding factor of differential cell type proportions across heterogeneous bulk samples. We propose a novel unsupervised deconvolution method for inferring cell type composition from bulk Hi-C data, the Two-step Hi-c UNsupervised DEconvolution appRoach (THUNDER). We conducted extensive simulations to test THUNDER based on combining two published single-cell Hi-C (scHi-C) datasets. THUNDER more accurately estimates the underlying cell type proportions compared to reference-free methods (e.g., TOAST, and NMF) and is more robust than reference-dependent methods (e.g. MuSiC). We further demonstrate the practical utility of THUNDER to estimate cell type proportions and identify cell-type-specific interactions in Hi-C data from adult human cortex tissue samples. THUNDER will be a useful tool in adjusting for varying cell type composition in population samples, facilitating valid and more powerful downstream analysis such as differential chromatin organization studies. Additionally, THUNDER estimated contact profiles provide a useful exploratory framework to investigate cell-type-specificity of the chromatin interactome while experimental data is still rare.

description: European geology ranges from old mountain chains with more or less altered magmatic and sedimentary deposits over glaciogenic materials from the recent Ice Ages to very young marine or alluvial deposits etc. Thus, the ground under our feet carries a large variety of raw materials from sand and gravel over granites and marbles to precious or critical metals and minerals. Humans have extracted these materials from the (sub)surface since prehistorical eras, and these indispensable substances have and still do to a very large extent contribute to the evolution of humankind, and through the last couple of decades, national or regional geological surveys have played an important role in mapping these resources. Most geological surveys host data on raw materials, however, data are typically organized in different ways from one country to another based on different geological traditions, legal frameworks etc. The MINTELL4EU project builds on previous projects to collect a selection of these national/regional raw material data, to store these in a central database, and finally to offer a visualization in a harmonized way at the European Geological Data Infrastructure (EGDI). This central database called MIN4EU includes, among other assets, the location of individual mineral occurrences and mines, aggregated statistical data at national level on production, trade, resources and reserves compiled in the electronic Minerals Yearbook, as well as data on test cases on UNFC. A brief overview of the database content and the resulting visualization through EGDI will be provided.

description: Handover measurement is responsible for finding a handover target and directly decides the performance of mobility management. It is governed by a complex combination of parameters dealing with multi-cell scenarios and system dynamics. A network design has to offer an appropriate handover measurement procedure in such a multi-constraint problem. The present paper proposes a unified framework for the network analysis and optimization. The exposition focuses on the stochastic modeling and addresses its key probabilistic events namely (i) suitable handover target found, (ii) service failure, (iii) handover measurement triggering, and (iv) handover measurement withdrawal. We derive their closed-form expressions and provide a generalized setup for the analysis of handover measurement failure and target cell quality by the best signal quality and \st{minimum duration outage} \textit{level crossing properties}. Finally, we show its application and effectiveness in today's 3GPP-LTE cellular networks.

description: This study was conducted with the aim of exploring the molecular and cellular mechanisms of action of the chrysin (natural flavonoid compound) on bladder tumour cell lines with different status of TP53 (RT4, 5637 and T24). The cells were treated with different concentrations of chrysin (20, 40, 60, 80 and 100 µM) to analyze the cell viability, nuclear division index, mutagenicity, apoptosis rates and expression of genes related to epigenetic events (DNMT1, HAT1 and HDAC1). Results showed that the treatment with chrysin reduced the cell viability and caused apoptosis, regardless TP53. Moreover, in the TP53-mutated cell lines, chrysin modulated the expression of the DNMT1, HAT1 and HDAC1 epigenetic genes, which might be a plus to the death observed in the cells with p53 mutation.
A century of warming on Caribbean reefs

description: The world’s oceans are warming at an unprecedented rate, causing dramatic changes to coastal marine systems, especially coral reefs. We used three complementary ocean temperature databases (HadISST, Pathfinder, and OISST) to quantify change in thermal characteristics of Caribbean coral reefs over the last 150 years (1871–2020). These sea surface temperature (SST) databases included in situ and satellite-derived measurements at multiple spatial resolutions. We also compiled a Caribbean coral reef database identifying 5,326 unique reefs across the region. We found that Caribbean reefs have been warming for at least a century. Regionally reef warming began in 1915, and for four of the eight Caribbean ecoregions we assessed, significant warming was detected for the latter half of the nineteenth century. Following the global mid-twentieth century stasis, warming resumed on Caribbean reefs in the early 1980s in some ecoregions and in the 1990s for others. On average, Caribbean reefs warmed by 0.18°C per decade during this period, ranging from 0.17°C per decade on Bahamian reefs (since 1988) to 0.26°C per decade on reefs within the Southern and Eastern Caribbean ecoregions (since 1981 and 1984, respectively). If this linear rate of warming continues, these already threatened ecosystems would warm by an additional ~1.5°C on average by 2100. We also found that marine heatwave (MHW) events are increasing in both frequency and duration across the Caribbean. Caribbean coral reefs now experience on average 5 MHW events annually, compared to 1 per year in the early 1980s, with recent events lasting on average 14 days. These changes in the thermal environment, in addition to other stressors including fishing and pollution, have caused a dramatic shift in the composition and functioning of Caribbean coral reef ecosystems.
Between war and revolution: French women and the sexual practices of everyday life, 1952-1967
Creators: name: Kreisel, Cynthia Sharrer

description: French women of all classes made everyday decisions in the postwar period in an effort to preserve their personal and sexual autonomy. They wrote letters to journals and papers, they read the works of scientists, doctors, and other women like themselves; they formed networks; they fought to free themselves from the bonds of sexual slavery; they found abortionists either clandestinely in France or abroad; and they fought for and obtained the right to family planning and the right to control their own bodies and lives. This project sheds light on the debates over sex, the activism surrounding sex, and the experiences of sex, all of which remain unexplored in the historiography of the immediate postwar years. Whereas many historians consider the postwar, pre-revolutionary period as one of "silence" regarding sexual and personal freedoms, the sources I have located indicate that women in fact actively created many key debates over fertility, sexuality, and sexual freedom that raged in this postwar environment. My thesis overturns the traditional view that students were the catalyst provoking revolution in May of 1968, by showing that women's struggles to control their own bodies and sexualities lay the groundwork for more radical rebellion in a conservative post-war world, in the two decades prior to 1968. This project proposes a paradigm shift that changes the definition and periodization of the "sexual revolution." Although there occurred a well-documented explosion of conversation and group formation based on identity politics after 1968 that has been described as a "sexual revolution," this older definition ignores the actions of women in the two earlier decades. These women's efforts successfully culminated in the Loi Neuwirth of 1967, both legalizing contraception and implementing a program of sexual education in French schools--a full six months before students and workers erupted in protest in May of 1968. French women's everyday resistances to the conservative and traditional postwar social order paved the road to revolution, however this study will also explore the complications and contradictions inherent in the complex postwar sexual world in which these women lived, loved, and agitated.

description: From empirically determined values of some of the characteristic constants associated with homogeneous nuclear matter at saturation and sub-saturation densities, within the framework of a Skyrme-inspired energy density functional, we construct an equation of state (EoS) of nuclear matter.This EoS is then used to predict values of density slope parameters of symmetry energy $L(ρ)$, isoscalar incompressibility $K(ρ)$ and a few related quantities. The close consonance of our predicted values with the currently available ones for the density dependence of symmetry energy and incompressibility gleaned from diverse approaches offers the possibility that our method may help in settling their values in tighter bounds. Extrapolation of our EoS at supranormal densities shows that it is in good harmony with the one extracted from experimental data.

Suppressing rebels, managing bureaucrats: state-building during the Taiping Rebellion, 1850-1864
Creators: name: Yeung, King-To
Publisher: name: No Publisher Supplied
Year: 2007

description: This study uses the historical case of the Taiping Rebellion (1850-64) to examine the process of state-building in an early modern empire. I focus on the interactions between volatile battles the Qing state launched against the Taipings and the changing social relationships among state actors embedded in preexisting rules and established organizational norms. In the early phase of the rebellion, 1851-1856, Peking tended to address the problem of controlling rebellion-ridden provinces by deploying state agents closely linked to the Manchu center. At the same time, negative sanctions, jurisdictional indifference, and interpersonal conflicts all surged among state agents. The rebels’ unpredictable actions, the sporadic sequencing of their battles, and their cross-jurisdictional mobility gave state actors numerous opportunities to act in ways that deviated from state interests. By the late 1850s, a new set of bureaucratic deployments emerged to address these problems. Colleague-officials had become more alike by dint of their ethnicities, provincial origins, and educational backgrounds. These changes in social ties and bureaucratic networks might have redrawn the parameters of the bureaucratic organization, creating a potential danger for central control. Applying the idea of “vacancy chains,᾿ I demonstrate that vacancies initiated in response to exigent demands in the battlefield could extensively impact the rest of the bureaucratic structure. The dynamics of vacancy chains brought together two distinct fields of social actions, linking rebellion suppression to the formation of the Qing bureaucratic field. By the 1870s, official careers appeared to be more stable than in the tumultuous 1850s, but the state bureaucracy as a whole had undergone—since the second half of the 1850s—a process of detachment. In the wake of the rebellion, provincial officials were more integrated into a provincial bureaucratic system that had been gradually made separate from the metropolitan bureaucracy. I ultimately provide a view of state-building as a continuous process whereby crisis and routine are intertwined, in which state rulers and their agents can at once build a “state᾿ together and take it apart.

description: Non-Abelian Josephson junction is a junction of non-Abelian color superconductors sandwiching an insulator, or non-Abelian domain wall if flexible, whose low-energy dynamics is described by a $U(N)$ principal chiral model with the conventional pion mass. A non-Abelian Josephson vortex is a non-Abelian vortex (color magnetic flux tube) residing inside the junction, that is described as a non-Abelian sine-Gordon soliton. In this paper, we propose Josephson instantons and Josephson monopoles, that is, Yang-Mills instantons and monopoles inside a non-Abelian Josephson junction, respectively, and show that they are described as $SU(N)$ Skyrmions and $U(1)^{N-1}$ vortices in the $U(N)$ principal chiral model without and with a twisted mass term, respectively. Instantons with a twisted boundary condition are reduced (or T-dual) to monopoles, implying that ${\mathbb C}P^{N-1}$ lumps are T-dual to ${\mathbb C}P^{N-1}$ kinks inside a vortex. Here we find $SU(N)$ Skyrmions are T-dual to $U(1)^{N-1}$ vortices inside a wall. Our configurations suggest a yet another duality between ${\mathbb C}P^{N-1}$ lumps and $SU(N)$ Skyrmions as well as that between ${\mathbb C}P^{N-1}$ kinks and $U(1)^{N-1}$ vortices, viewed from different host solitons. They also suggest a duality between fractional instantons and bions in the ${\mathbb C}P^{N-1}$ model and those in the $SU(N)$ principal chiral model.

description: Combinatorial threshold-linear networks (CTLNs) are a special class of inhibition-dominated TLNs defined from directed graphs. Like more general TLNs, they display a wide variety of nonlinear dynamics including multistability, limit cycles, quasiperiodic attractors, and chaos. In prior work, we have developed a detailed mathematical theory relating stable and unstable fixed points of CTLNs to graph-theoretic properties of the underlying network. Here we find that a special type of fixed points, corresponding to core motifs, are predictive of both static and dynamic attractors. Moreover, the attractors can be found by choosing initial conditions that are small perturbations of these fixed points. This motivates us to hypothesize that dynamic attractors of a network correspond to unstable fixed points supported on core motifs. We tested this hypothesis on a large family of directed graphs of size n = 5, and found remarkable agreement. Furthermore, we discovered that core motifs with similar embeddings give rise to nearly identical attractors. This allowed us to classify attractors based on structurally-defined graph families. Our results suggest that graphical properties of the connectivity can be used to predict a network’s complex repertoire of nonlinear dynamics.

description: The paper analyses India's Northeast region in terms of multiple conceptualisations of geopolitical imaginaries. The work begins with a general proposition that such configurations are fluid because of changing narratives of the spatial constructs as well as problematic due to the inherent contradictions and conflict between the spatial imaginaries. The paper then highlights two recent initiatives that reflect the conflict between two different kinds of spatial imaginaries – (a) The Act East Policy that conceptualises the region as an extended economic space inclusive enough even to incorporate the neighbouring countries of Bangladesh and Myanmar. (b) The reactions in the Northeast to the Citizenship Amendment Act 2019 that reflect a communitarian vision of a region that is an exclusive one based on ethnic lines. While exploring the two initiatives in the context of spatial imaginaries, the paper attempts to (a) Analyse India’s Act East Policy and the consequent visualisation of North East India as a zone of connectivity with India’s Eastern neighbours. (b) Analyse the Citizenship Amendment Act 2019 and its vigorous regional response. (c) Explore the scope of the coexistence of an extended economic space despite the antithetical aspect of exclusive ethnic space.
How can double-barred galaxies be long-lived?

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Double-barred galaxies account for almost one third of all barred galaxies, suggesting that secondary stellar bars, which are embedded in large-scale primary bars, are long-lived structures. However, up to now it has been hard to self-consistently simulate a disc galaxy that sustains two nested stellar bars for longer than a few rotation periods. N-body/hydrodynamical simulations including star formation recipes have been performed. Their properties have been compared with the most recent observational data in order to prove that they are representative of double-barred galaxies, even SB0. Overlaps in dynamical resonances and bar modes have been looked for using Fourier spectrograms. Double-barred galaxies have been successfully simulated with lifetimes as long as 7 Gyr. The stellar population of the secondary bar is younger on average than for the primary large-scale bar. An important feature of these simulations is the absence of any resonance overlap for several Gyr. In particular, there is no overlap between the primary bar ILR and the secondary bar corotation. Therefore, mode coupling cannot sustain the secondary bar mode. Star formation is identified here as possibly being responsible for bringing energy to the nuclear mode. Star formation is also responsible for limiting the amount of gas in the central region which prevents the orbits sustaining the secondary bar from being destroyed. Therefore, the secondary bar can dissolve but reappear after approx. 1 Gyr. When star formation is switched off the dynamical perturbation associated with the secondary bar needs several Gyr to fully vanish. Double-bars can be long-lived in numerical simulations with a gaseous component, even in the absence of overlap of resonances or mode coupling, provided that star formation remains active in the central region where the nuclear bar lies.

description: Using information from allele-specific gene expression (ASE) can improve the power to map gene expression quantitative trait loci (eQTLs). However, such practice has been limited, partly due to computational challenges and lack of clarification on the size of power gain or new findings besides improved power. We have developed geoP, a computationally efficient method to estimate permutation p-values, which makes it computationally feasible to perform eQTL mapping with ASE counts for large cohorts. We have applied geoP to map eQTLs in 28 human tissues using the data from the Genotype-Tissue Expression (GTEx) project. We demonstrate that using ASE data not only substantially improve the power to detect eQTLs, but also allow us to quantify individual-specific genetic effects, which can be used to study the variation of eQTL effect sizes with respect to other covariates. We also compared two popular methods for eQTL mapping with ASE: TReCASE and RASQUAL. TReCASE is ten times or more faster than RASQUAL and it provides more robust type I error control.

description: The creation and application of 3D geological models has become increasingly important within the geological surveys in recent years. In the joint project TUNB (Tieferer Untergrund Norddeutsches Becken - Deeper Underground North German Basin), the geological surveys of northern Germany together with the Federal Institute for Geosciences and Natural Resources (BGR) created a coordinated and largely border-harmonised 3D geological model of the North German Basin for their respective state areas. The objective of this presentation is to describe the approach to develop a generalised 3D geological model from the base Zechstein to the Tertiary of Lower Saxony based on heterogeneous and inconsistent data within this project. The data basis for the current model was the predecessor model GTA3D, digitally available borehole data, depth migrated 2D and 3D seismic data and supplementary data such as thickness and structural maps of lithostratigraphic units. 3D geological modelling was carried out with Emerson SKUA-GOCAD, taking into account the project-related generalisation specifications and geological plausibility. The problem of inconsistencies occurring in the input data due to their different sources, quantity, and quality could not be solved by automated procedures. Instead, this was often subject to the geological expertise of the modeller, who took into account the regional geological conditions to weight the data and create a model that is as free of contradictions as possible. We demonstrate how the integration of new data led to changes in the geometry of salt structures and lithostratigraphic horizons with respect to the predecessor model.

description: Neben der bereits bekannten Relevanz der sozialen Medien für junge Erwachsene belegen aktuelle Studien, dass sie das Potenzial haben, das Gesundheitsverhalten ihrer Konsumenten positiv zu beeinflussen. Jedoch gibt es bis dato keine wissenschaftlichen Erkenntnisse darüber, wovon solch ein positiver Einfluss abhängt. Daher wurde in dieser ersten Studie empirisch untersucht, ob möglicherweise die spezifische Selbstwirksamkeit für ein bestimmtes Gesundheitsverhalten (hier: gewohnheitsmäßige Meditation und Achtsamkeit zur Stressreduktion) einen Moderator-Effekt auf den Einfluss von sozialen Medien hat und, ob dieser Effekt abhängig von der Qualität der Selbstwirksamkeit ist. Dazu wurden von 121 Probanden im Alter von 18 bis 29 Jahren die Nutzungsweise von sozialen Medien, die individuelle generelle und spezifische Selbstwirksamkeit für das ausgewählte Gesundheitsverhalten und dessen Gewohnheitsmäßigkeit erfasst. Entgegen den Erwartungen konnte kein Moderator-Effekt und keine Korrelation nachgewiesen werden. Die Ergebnisse deuten jedoch darauf hin, dass zusätzlich (oder eher) die spezifische Selbstwirksamkeit für die Nutzung von sozialen Medien von großer Relevanz für die Bestätigung der hier aufgestellten Hypothesen sein könnte. Deshalb sollten zukünftige Studien auf diesem Gebiet diese zwingend erfassen. Sollten sich die Hypothesen in der weiterführenden Forschung bestätigen, würde dies die Gesundheitsförderung des Einzelnen und der Gesellschaft positiv beeinflussen.

description: We have studied the polarization dependence of coherent phonons in the topological insulator Bi2Te3. Using polarization-dependent femtosecond pump-probe spectroscopy, we measured coherent phonons as a function of angle when the pump and probe polarizations were fixed, and the crystal orientation was rotated. For isotropic detection, depending on the spot position, oscillations either from only low- and high-frequency phonons of A1g symmetry, or in addition from the mode at 3.6 THz were observed. All the modes were found to be independent of the orientation of electric field vector with respect to the crystal axes testifying to their full symmetry while no modes of lower symmetry appeared in any polarization geometry. For anisotropic detection both modes of Eg symmetry could be detected, but their amplitudes were considerably smaller than those of A1g symmetry. To clarify the coherent phonon assignment and the process of coherent phonon generation in Bi2Te3, the time-domain measurements were complemented by spontaneous Raman scattering. The comparison of frequency- and time-domain results and the polarization dependence suggest that the 3.6 THz mode belongs to crystalline Te arising due to tellurium segregation. A discrepancy between the time- and frequency domain data is discussed.

description: The paper analyses India's Northeast region in terms of multiple conceptualisations of geopolitical imaginaries. The work begins with a general proposition that such configurations are fluid because of changing narratives of the spatial constructs as well as problematic due to the inherent contradictions and conflict between the spatial imaginaries. The paper then highlights two recent initiatives that reflect the conflict between two different kinds of spatial imaginaries – (a) The Act East Policy that conceptualises the region as an extended economic space inclusive enough even to incorporate the neighbouring countries of Bangladesh and Myanmar. (b) The reactions in the Northeast to the Citizenship Amendment Act 2019 that reflect a communitarian vision of a region that is an exclusive one based on ethnic lines. While exploring the two initiatives in the context of spatial imaginaries, the paper attempts to (a) Analyse India’s Act East Policy and the consequent visualisation of North East India as a zone of connectivity with India’s Eastern neighbours. (b) Analyse the Citizenship Amendment Act 2019 and its vigorous regional response. (c) Explore the scope of the coexistence of an extended economic space despite the antithetical aspect of exclusive ethnic space.

description: Using a solitonic model of nuclear matter, the BPS Skyrme model, we compare neutron stars obtained in the full field theory, where gravitational back reaction is completely taken into account, with calculations in a mean-field approximation using the Tolman-Oppenheimer-Volkoff approach. In the latter case, a mean-field-theory equation of state is derived from the original BPS field theory. We show that in the full field theory, where the energy density is non-constant even at equilibrium, there is no universal and coordinate independent equation of state of nuclear matter, in contrast to the mean-field approximation. We also study how neutron star properties are modified by going beyond mean field theory, and find that the differences between mean field theory and exact results can be considerable. Further, we compare both exact and mean-field results with some theoretical and phenomenological constraints on neutron star properties, demonstrating thus the relevance of our model even in its most simple version.

description: Background The Government of Indonesia is determined to follow global commitments to reduce the neonatal mortality rate. Yet, there is a paucity of information on contributing factors and causes of neonatal deaths, particularly at the sub-national level. This study describes care-seeking during neonates’ fatal illnesses and their causes of death. Methods We conducted a cross-sectional community-based study to identify all neonatal deaths in Serang and Jember Districts, Indonesia. Follow-up interviews were conducted with the families of deceased neonates using an adapted verbal and social autopsy instrument. Cause of death was determined using the InSilicoVA algorithm. Results The main causes of death of 259 neonates were prematurity (44%) and intrapartum-related events (IPRE)-mainly birth asphyxia (39%). About 83% and 74% of the 259 neonates were born and died at a health facility, respectively; 79% died within the first week after birth. Of 70 neonates whose fatal illness began at home, 59 (84%) sought care during the fatal illness. Forty-eight of those 59 neonates went to a formal care provider; 36 of those 48 neonates (75%) were moderately or severely ill when the family decided to seek care. One hundred fifteen of 189 neonates (61%) whose fatal illnesses began at health facilities were born at a hospital. Among those 115, only 24 (21%) left the hospital alive–of whom 16 (67%) were referred by the hospital. Conclusions The high proportion of deaths due to prematurity and IPRE suggests the need for improved management of small and asphyxiated newborns. The moderate to severe condition of neonates at the time when care was sought from home highlights the importance of early illness recognition and appropriate management for sick neonates. Among deceased neonates whose fatal illness began at their delivery hospital, the high proportion of referrals may indicate issues with hospital capability, capacity, and/or cost.

description: The KAP-C questionnaire or survey tool was developed and validated to assess the knowledge, attitude, and practice of pharmacists and pharmacy students towards ChatGPT in pharmacy practice and education. ChatGPT is an advanced conversational artificial intelligence (AI). This KAP-C tool aims to uncover insights into how ChatGPT's capabilities might be resourceful for pharmacy practice and education, particularly in low- and middle-income countries (LMICs) like Nigeria, Pakistan, and Yemen. The KAP-C tool development and validation processes involved a comprehensive literature search to identify relevant constructs, content validation by a panel of experts for items' relevancy using the content validity index (CVI), face validation by sample participants for items clarity using the face validity index (FVI), readability and difficulty index using the Flesch-Kincaid Readability Test, Gunning Fog Index, or Simple Measure of Gobbledygook (SMOG), assessment of reliability using internal consistency (Cronbach’s alpha), and exploratory factor analysis (EFA) to determine the underlying factor structures (eigenvalues, scree plot analysis, factor loadings, and varimax). The protocol describing all the procedures involved in the development and validation of the KAP-C tool has been published elsewhere and is here (https://doi.org/10.1007/s40615-023-01696-1) or on request from the author.
MEASURING CMB POLARIZATION WITH THE LSPE EXPERIMENT: SIMULATION AND SENSITIVITY STUDIES FOR THE STRIP INSTRUMENT
Creators: name: CAPRIOLI, SILVIA
Publisher: name: Universit� degli Studi di Milano
Year: 2020

description: The search of primordial B-mode fluctuations in the polarization pattern of the Cosmic Microwave Background (CMB) is one of the most active and challenging fields in modern observational cosmology. A detection of primordial B-modes would in fact provide a strong evidence in favour of the Inflationary paradigm, shedding light on the physics of the early Universe. The Large Scale Polarization Explorer is an Italian-led experiment designed to measure the CMB polarization at large angular scales. Its primary goals are the constraint of the B-mode component down to r = 0.03 and the study of the polarized emissions of our Galaxy. LSPE will observe 25% of the sky in the Northern hemisphere relying on the synergy of two di?erent instruments, a balloon-borne experiment (SWIPE) and a ground-based telescope (STRIP), complementary for frequency coverage and technology. STRIP, in particular, will observe the 43 GHz sky with an array of 49 polarimeters in order to characterize the Galactic synchrotron signal. STRIP will be installed at the Teide Observatory in Tenerife (Canary Islands, Spain) in mid-late 2021, and at least two years of observations will follow. This PhD thesis describes the Unit Tests campaign of STRIP polarimetric modules, from the test procedures to the data analysis, focusing in particular on the characterization of the bandpass response. A simulation pipeline, developed for the STRIP experiment in order to assess its scientific performance, is also presented. Particular attention is given to the generation of realistic data streams and to the implementation of a map-maker, following the destriping technique. The results of end-to-end simulations of STRIP observation, also exploiting the results of the Unit Tests, are finally presented. In particular, the behaviour of the destriping algorithm in the specific case of the STRIP instrument has been evaluated, together with the impact of some systematics e?ects.
