description: Self-assembly in natural and synthetic molecular systems can create complex aggregates or materials whose properties and functionality rises from their internal structure and molecular arrangement. The key microscopic features that control such assemblies remain poorly understood, nevertheless. Using classical density functional theory we demonstrate how the intrinsic length scales and their interplay in terms of interspecies molecular interactions can be used to tune soft matter self-assembly. We apply our strategy to two different soft binary mixtures to create guidelines for tuning intermolecular interactions that lead to transitions from fully miscible, liquid-like uniform state to formation of simple and core-shell aggregates, and mixed aggregate structures. Furthermore, we demonstrate how the interspecies interactions and system composition can be used to control concentration gradients of component species within these assemblies. The insight generated by this work contributes towards understanding and controlling soft multi-component self-assembly systems. Additionally, our results aid in understanding complex biological assemblies and their function and provide tools to engineer molecular interactions in order to control polymeric and protein-based materials, pharmaceutical formulations, and nanoparticle assemblies.

description: When a capillary is inserted into a liquid, the liquid will rapidly flow into it. This phenomenon, well studied and understood on the macroscale, is investigated by Molecular Dynamics simulations for coarse-grained models of nanotubes. Both a simple Lennard-Jones fluid and a model for a polymer melt are considered. In both cases after a transient period (of a few nanoseconds) the meniscus rises according to a $\sqrt{\textrm{time}}$-law. For the polymer melt, however, we find that the capillary flow exhibits a slip length $δ$, comparable in size with the nanotube radius $R$. We show that a consistent description of the imbibition process in nanotubes is only possible upon modification of the Lucas-Washburn law which takes explicitly into account the slip length $δ$.

Broken Scaling Neutrino Mass Matrix and Leptogenesis based on A$_4$ Modular invariance

Year: 2021
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this work, we have proposed a modular $A_4$ symmetric model of neutrino mass which, simultaneously, explains observed baryon asymmetry of the Universe(BAU). In minimal extension of the standard model(SM) with two right-handed neutrinos we work in a supersymmetric framework. At Type-I seesaw level, the model predicts scaling in the neutrino mass matrix. In order to have correct low energy phenomenology, we propose two possible scenarios of scale-breaking in the neutrino mass matrix emanating from Type-I seesaw. Scenario-1 is based on the dimension-5 Weinberg operator whereas scenario-2 implements Type-II seesaw via scalar triplet Higgs superfields($Δ,\barΔ$). Interestingly, the breaking patterns in both, otherwise dynamically different scenarios, are similar which can be attributed to the same charge assignments of superfields($Δ,\barΔ$) and the Higgs superfield $H_u$ under modular $A_4$ symmetry. The breaking is found to be proportional to the Yukawa coupling of modular weight 10($Y_{1,1'}^{10}$). We, further, investigates the predictions of the model under scenario-2 (Type-I+II) for neutrino mass, mixings and matter-antimatter asymmetry of the Universe. The model predicts normal hierarchical neutrino masses and provide a robust range ($0.05-0.08$)eV for sum of neutrino masses($\sum m_{i}$). Lepton number violating $0νββ$ decay amplitude($M_{ee}$) is obtained to lie in the range ($0.04-0.06$)eV. Future $0νββ$ decay experiments such as NEXT and nEXO shall pose crucial test for the model. Both $CP$ conserving and $CP$ violating solutions are allowed in the model. Interesting correlations are obtained, specially, between Yukawa couplings of modular weight 2 and complex modulus $τ$. The model exhibit consistent explanation of BAU for right-handed Majorana neutrino mass scale in the range ($(1-5)\times10^{13}$)GeV.

description: We calculate electronic single-particle properties of short-range ordered stripe states, using Monte-Carlo simulations of collective charge-density wave (CDW) order parameters coupled to fermions on a 2d square lattice. For superconducting bond-centered stripes with a d-wave form factor, we find a valence-bond "glass" which coexists with low-energy quasiparticles featuring interference phenomena, in agreement with recent scanning-tunneling-microscopy (STM) measurements on underdoped BSCCO and CaNaCuOCl. Together with earlier work, our calculations provide a link between CDW features seen in STM and those in magnetic neutron scattering.

description: We point out that the inclusion of a string component contributing around 5% to the CMB power spectrum amplitude on large scales can increase the preferred value of the spectral index n_s of density fluctuations measured by CMB experiments. While this finding applies to any cosmological scenario involving strings, we consider in particular models of supersymmetric hybrid inflation, which predict n_s >= 0.98, in tension with the CMB data when strings are not included. Using MCMC analysis we constrain the parameter space allowed for F- and D-term inflation. For the F-term model, using minimal supergravity corrections, we find that \logκ= -2.34\pm 0.38 and M= (0.518\pm 0.059) * 10^16 GeV. The inclusion of non-minimal supergravity corrections can modify these values somewhat. In the corresponding analysis for D-term inflation, we find \logκ= -4.24\pm 0.19 and m_FI= (0.245\pm 0.031) * 10^16 GeV. Under the assumption that these models are correct, these results represent precision measurements of important parameters of a Grand Unified Theory. We consider the possible uncertainties in our measurements and additional constraints on the scenario from the stochastic background of gravitational waves produced by the strings. The best-fitting model predicts a B-mode polarization signal \approx 0.3 μK rms peaking at l \approx 1000. This is of comparable amplitude to the expected signal due to gravitational lensing of the adiabatic E-mode signal on these scales.

description: The hadron resonance gas (HRG) model is often believed to correctly describe the confined phase of QCD. This assumption is the basis of many phenomenological works on QCD thermodynamics and of the analysis of hadron yields in relativistic heavy ion collisions. We use first-principle lattice simulations to calculate corrections to the ideal HRG. Namely, we determine the sub-leading fugacity expansion coefficients of the grand canonical free energy, receiving contributions from processes like kaon-kaon or baryon-baryon scattering. We achieve this goal by performing a two dimensional scan on the imaginary baryon number chemical potential ($μ_B$) - strangeness chemical potential ($μ_S$) plane, where the fugacity expansion coefficients become Fourier coefficients. We carry out a continuum limit estimation of these coefficients by performing lattice simulations with temporal extents of $N_τ=8,10,12$ using the 4stout-improved staggered action. We then use the truncated fugacity expansion to extrapolate ratios of baryon number and strangeness fluctuations and correlations to finite chemical potentials. Evaluating the fugacity expansion along the crossover line, we reproduce the trend seen in the experimental data on net-proton fluctuations by the STAR collaboration.

The role of a community-based cardiac education program for post-myocardial infarction patients

Publisher: name: University of British Columbia
Year: 2008

description: This exploratory study examined the role of a community-based cardiac education program for post-myocardial infarction patients in affecting their health knowledge, health beliefs, and health behaviors. Four sources of data were used to address this purpose: components of both a hospital and a community-based program, Home Care nurses, and post-myocardial infarction patients. The framework for the study was the PRECEDE-PROCEED health promotion planning model (Green & Kreuter, 1991), serving as an organizational framework for instrument development and data analysis. In addition, it provided the conceptual basis for understanding the context in which education is offered, and ways in which the program addressed factors within that context. Analysis of the hospital program was done to determine the baseline level of cardiac education provided to patients before hospital discharge. Both programs were analyzed in relation to philosophical framework, content, implementation, and evaluation. A questionnaire addressed Home Care nurses' perceptions of the intended and unintended outcomes of the Home Care Program. An interview schedule was administered to first-myocardial infarction patients, to determine health behaviors, health knowledge, health beliefs, and perception of both programs. This interview schedule was used both for the in-hospital interview, and a follow-up interview at six to eight weeks post-discharge. A qualitative approach to data analysis enabled exploration of emergent themes within and across data sources. Conclusions of the study related to themes identified through the qualitative approach and included the following: 1. The primary difference between the Hospital and Home Care Program related to method of implementation; a standardized versus an interactive, individualized approach; 2. Predisposing factors, such as beliefs, motivation, and culture were of major significance in adoption of recommended behavior changes; 3. Cultural factors played an important role in the social context of the patient and family, thus affecting other antecedents to behavior; 4. The environment in which the education was offered was a key element in determining the effect of the program on promoting behavior and lifestyle change.

description: Private distributed learning studies the problem of how multiple distributed entities collaboratively train a shared deep network with their private data unrevealed. With the security provided by the protocols of blind quantum computation, the cooperation between quantum physics and machine learning may lead to unparalleled prospect for solving private distributed learning tasks. In this paper, we introduce a quantum protocol for distributed learning that is able to utilize the computational power of the remote quantum servers while keeping the private data safe. For concreteness, we first introduce a protocol for private single-party delegated training of variational quantum classifiers based on blind quantum computing and then extend this protocol to multiparty private distributed learning incorporated with differential privacy. We carry out extensive numerical simulations with different real-life datasets and encoding strategies to benchmark the effectiveness of our protocol. We find that our protocol is robust to experimental imperfections and is secure under the gradient attack after the incorporation of differential privacy. Our results show the potential for handling computationally expensive distributed learning tasks with privacy guarantees, thus providing a valuable guide for exploring quantum advantages from the security perspective in the field of machine learning with real-life applications.

description: Experiments of pure tensile fracture in brittle gels reveal a new dynamic oscillatory instability whose onset occurs at a critical velocity, Vc = 0.87 Cs, where Cs is the shear wave speed. Until Vc crack dynamics are well described by linear elastic fracture mechanics (LEFM). These extreme speeds are obtained by suppression of the micro-branching instability, which occurs when sample thicknesses are made comparable to the minimum micro-branch width. The wavelength of these sinusoidal oscillations is independent of the sample dimensions, thereby suggesting that a new intrinsic scale exists that is unrelated to LEFM.

Constraints on the initial state of PbPb collisions via measurements of Z boson yields and azimuthal anisotropy at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV

description: The CMS experiment at the LHC has measured the differential cross sections of Z bosons decaying to pairs of leptons, as functions of transverse momentum and rapidity, in lead-lead collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The measured Z boson elliptic azimuthal anisotropy coefficient is compatible with zero, showing that Z bosons do not experience significant final-state interactions in the medium produced in the collision. Yields of Z bosons are compared to Glauber model predictions and are found to deviate from these expectations in peripheral collisions, indicating the presence of initial collision geometry and centrality selection effects. The precision of the measurement allows, for the first time, for a data-driven determination of the nucleon-nucleon integrated luminosity as a function of lead-lead centrality, thereby eliminating the need for its estimation based on a Glauber model.

description: The transport properties of junctions composed of a central region tunnel-coupled to external electrodes are frequently studied within the single-impurity Anderson model with Hubbard on-site interaction. In the present work, we supplement the model with an important ingredient, namely the charge-bond interaction, also known as correlated or assisted hopping. Correlated hopping enters the second-quantised Hamiltonian, written in the Wannier representation, as an off-diagonal many-body term. Using the equation of motion technique, we study the effect of the correlated hopping on the spectral and transport characteristics of a two-terminal quantum dot. Two different Green functions (GFs) appear: one of them describes the spectral properties of the quantum dot, the other the transport properties of the system. The calculation of the transport GF requires the knowledge of the spectral one. We use decoupling procedures similar to those which properly describe the standard Anderson model within the Kondo regime and outside of it. For an arbitrary ratio $x$ between the amplitudes of correlated and single-particle hopping terms, the transport GF fulfils the $x \leftrightarrow 2-x$ symmetry of the model. The average occupation of the dot also obeys this symmetry, albeit the spectral function of the quantum dot, calculated within an analogous decoupling scheme as for the transport GF, does not. We identify the physical reason for this behavior, and propose a way to cure it. Since the correlated-hopping term breaks the particle-hole symmetry of the model and modifies all transport characteristics of the system, the detailed knowledge of its influence on measurable characteristics is a prerequisite for its experimental detection. Simple, experimentally feasible methods are proposed.

description: In case-based reasoning, the adaptation of a source case in order to solve the target problem is at the same time crucial and difficult to implement. The reason for this difficulty is that, in general, adaptation strongly depends on domain-dependent knowledge. This fact motivates research on adaptation knowledge acquisition (AKA). This paper presents an approach to AKA based on the principles and techniques of knowledge discovery from databases and data-mining. It is implemented in CABAMAKA, a system that explores the variations within the case base to elicit adaptation knowledge. This system has been successfully tested in an application of case-based reasoning to decision support in the domain of breast cancer treatment.

description: Abstract

The proliferation of technological advancements and the widespread adoption of smartphones has significantly impacted the shift from traditional offline transactions to online. The necessity for individuals to conduct financial transactions at their convenience and from any location has prompted banks to adjust their services accordingly. This research employs digital banks in Indonesia as the subjects of investigation, specifically focusing on the digital bank with the highest number of downloads and usage among Indonesian users. This research utilizes a quantitative approach and collects data from a sample of 413 participants by administering an online questionnaire. All participants in the study have prior experience with digital banking applications. This study aims to examine the various elements that impact user satisfaction with digital bank applications and the extent to which each component contributes to users' satisfaction levels. This study examined the many elements associated with utilizing Service Quality, Quality Systems, Security, Performance Expectations, Trust, Design Application, and Bank Image. The present study utilized Partial Least Squares Structural Equation Modeling (PLS-SEM) as the analytical approach, with the data being analyzed using the SmartPLS software application. All variables, except for quality system and security, exhibit a positive and statistically significant impact on satisfaction. Furthermore, these three variables demonstrate a positive and statistically significant influence on brand image. Furthermore, it has been found that satisfaction has a noteworthy and substantial impact on customer satisfaction. This study is anticipated to support Digital Bank in enhancing and optimizing its banking applications and services, fostering continuous improvement in customer satisfaction and brand image.

description: Repulsive soft-core atomic systems may undergo clustering if their density is high enough that core overlap is unavoidable. In one-dimensional quantum systems, it has been shown that this instability triggers a transition from a Luttinger liquid to various cluster Luttinger liquids. Here, we focus on the Luttinger liquid regime and theoretically study the evolution of key observables related to density fluctuations, that manifest a striking dependence on density. We tune the interaction so that the low-density regime corresponds to a Tonks-Girardeau gas, and show that as the density is increased the system departs more and more from Tonks-Girardeau behavior, displaying a much larger compressibility as well as rotonic excitations that finally drive the clustering transition. We compare various theoretical approaches, which are accurate in different regimes. Using quantum Monte Carlo methods and analytic continuation as a benchmark, we investigate the regime of validity of the mean-field Bogoliubov and the real-time multiconfiguration time-dependent Hartree-Fock approaches. Part of the behavior that we describe should be observable in ultracold Rydberg-dressed gases, provided that system losses are prevented.

description: The purpose of this thesis is to present the pastoral aspects of the Theology of Baptism of saint Nicolaos Kavasilas. These pastoral aspects concern its therapeutic (healing) and its mystic character. In this essay are being discussed the below-mentioned pastoral aspects: How the Baptism sacrament reverses the original sin and gives a new birth ‘in Christ’ for the baptized person. How the Theology and the Economy can lead man in a mystical way to the sacrament. How the Baptism ‘summarizes’ the time and is lived by the man in a positive way. How it also leads in a mystical way the man in order to enter the Kingdom of Heaven through the life in Christ. Moreover, how it restores human will through a ‘synergistic’ way. Baptism being an indelible sacrament how it morally renovates the human being. The essay also discusses the subject of the ‘direct baptism’ from the Bridegroom of the Church. In conclusion, how the Baptism sacrament is the most perfect and fullest way of knowing God
Jane Austen’s novels from the perspective of the theories and practices of modern-day psychotherapy
Creators: name: Green, Adrienne
Publisher: name: Lancaster University
Year: 2019

description: This thesis demonstrates the strong similarities between the subtle aspects of Austen’s complex characterisations and the perceptions and understandings of human psychology that are encompassed within twentieth-century models of psychotherapy. In this context, I show how the theoretical frameworks and principles that underpin different twentieth-century psychotherapeutic approaches facilitate the identification and definition of Austen’s frequently acknowledged insights into human nature. While the psychotherapeutic terms used in this exploration of Austen’s work have emerged in the post-Austen era, there is no suggestion in this discussion that Austen had some prescience of future models of psychotherapy. My intent is to highlight the resonances between Austen’s insights and modern-day psychotherapeutic formulations, and to show how these resonances illuminate Austen’s extraordinary psychological perspicuity. The analysis of Austen’s novels from this perspective leads to interpretations of Austen’s characters that at times differ substantially from existing perceptions and at others reinforce or enhance previous readings. The question of whether Austen took a didactic moral position in her novels is a central issue within this thesis. I explore the differing opinions expressed in existing critiques of her novels in this regard, and challenge the view that Austen intended to direct her readers towards a fixed moral code. I argue that Austen’s attitude to her craft suggests instead an intention on the author’s part to bring about enhanced self-awareness and a movement towards greater self-directed autonomy in her readers.

description: We investigate strong gravitational lensing in the concordance $Λ$CDM cosmology by carrying out ray-tracing along past light cones through the Millennium Simulation, the largest simulation of cosmic structure formation ever carried out. We extend previous ray-tracing methods in order to take full advantage of the large volume and the excellent spatial and mass resolution of the simulation. As a function of source redshift we evaluate the probability that an image will be highly magnified, will be highly elongated or will be one of a set of multiple images. We show that such strong lensing events can almost always be traced to a single dominant lensing object and we study the mass and redshift distribution of these primary lenses. We fit analytic models to the simulated dark halos in order to study how our optical depth measurements are affected by the limited resolution of the simulation and of the lensing planes that we construct from it. We conclude that such effects lead us to underestimate total strong-lensing cross sections by about 15 percent. This is smaller than the effects expected from our neglect of the baryonic components of galaxies. Finally we investigate whether strong lensing is enhanced by material in front of or behind the primary lens. Although strong lensing lines-of-sight are indeed biased towards higher than average mean densities, this additional matter typically contributes only a few percent of the total surface density.

description: As large optical quasar surveys for damped Lya become a reality and the study of star forming gas in the early Universe achieves statistical robustness, it is now vital to identify and quantify the sources of systematic error. Because the nature of optically-selected quasar surveys makes them vulnerable to dust obscuration, we have undertaken a radio-selected quasar survey for damped Lya systems to address this bias. We present the definition and results of this survey. We then combine our sample with the CORALS dataset to investigate the HI column density distribution function f(N) of damped Lya systems toward radio-selected quasars. We find that f(N) is well fit by a power-law f(N) = k_1 N^alpha_1, with log k_1 = 22.90 and alpha_1 = -2.18. This power-law is in excellent agreement with that of optically-selected samples at low N(HI), an important yet expected result given that obscuration should have negligible effect at these gas columns. However, because of the relatively small size of the radio-selected sample, 26 damped Lya systems in 119 quasars, f(N) is not well constrained at large N(HI) and the first moment of the HI distribution function, Omega_g, is, strictly speaking, a lower limit. The power-law is steep enough, however, that extrapolating it to higher column densities implies only a modest, logarithmic increase in Omega_g. The radio-selected value of Omega_g = 1.15 x 10^-3, agrees well with the results of optically-selected surveys. While our results indicate that dust obscuration is likely not a major issue for surveys of damped Lya systems, we estimate that a radio-selected sample of approximately 100 damped Lya systems will be required to obtain the precision necessary to absolutely confirm an absence of dust bias.

Teacher collaboration : a study of the teaching-learning relationship
Creators: name: Da Costa, José Laranjo
Publisher: name: University of British Columbia
Year: 2009

description: This study served two purposes. First, it provided a synthesis of the literature relating teacher collaboration to teaching-learning outcomes. Second, it investigated empirically the existence of links posited in the literature reviewed. From the literature a conceptual framework was synthesized regarding the postulated relationships, with respect to teacher collaboration, between and among: (1) teacher trust for the teaching partner, (2) the teaching partner's supervisory beliefs, (3) teacher efficacy, (4) teacher reflection, (5) teacher classroom behaviour, (6) pupil achievement, (7) pupil attitudes, and (8) pupil behaviour. The general question under investigation was: "What is the relationship between teacher participation in a teacher collaboration programme and teaching-learning outcomes? To test the aptness of the model, data for each of the eight variables listed above were collected at the beginning and at the end of the 1991/92 school year from four collaboration groups and one non-collaboration group. The five groups represented the following teacher collaboration strategies: (1) collaborative consultation, (2) collaborative consultation in a team teaching environment, (3) collaborative consultation without direct classroom observation by the teaching partner, (4) collegial consultation without direct classroom observation by the teaching partner, and (5) teachers who did not work with a teaching partner. The groups self-selected from two School Districts in the Lower Mainland of British Columbia. A total of 30 teachers and 476 pupils formed the sample for the study. The data were analyzed using two multivariate techniques, namely: (1) Multivariate Analysis of Variance (MANOVA), and (2) Canonical Analysis (CA). Analysis of the evidence collected using MANOVA suggests that teacher participation in various collaboration programs is associated with differing teaching-learning outcomes. Analysis of the ungrouped data using CA suggests the existence of positive relationships between general teacher efficacy, teacher behaviours, and pupil attitudes and behaviours. It was concluded that the results are potentially useful in two ways. First, the results may further the development of theory in the area of collaborative consultation in particular and teacher collaboration in general. Second, if used cautiously, the results are practically useful for teachers and administrators who may want to put a programme of collaborative consultation into place.

description: Automatic program repair (APR) is crucial to improve software reliability. Recently, neural machine translation (NMT) techniques have been used to fix software bugs automatically. While promising, these approaches have two major limitations. Their search space often does not contain the correct fix, and their search strategy ignores software knowledge such as strict code syntax. Due to these limitations, existing NMT-based techniques underperform the best template-based approaches. We propose CURE, a new NMT-based APR technique with three major novelties. First, CURE pre-trains a programming language (PL) model on a large software codebase to learn developer-like source code before the APR task. Second, CURE designs a new code-aware search strategy that finds more correct fixes by focusing on compilable patches and patches that are close in length to the buggy code. Finally, CURE uses a subword tokenization technique to generate a smaller search space that contains more correct fixes. Our evaluation on two widely-used benchmarks shows that CURE correctly fixes 57 Defects4J bugs and 26 QuixBugs bugs, outperforming all existing APR techniques on both benchmarks.

description: The aim of the present thesis was the literature review of immediate placement and immediate loading of a single dental implant in the aesthetic zone. There was a report on the historical background of dental implants and then the indications and contraindications were thoroughly analyzed. The surgical procedure of the immediate placement of a single dental implant was also analyzed. At the end, we also examined the factors that influence the immediate placement-immediate loading, such as surgical factors, factors related to the surgical bed of the host, factors related to the implant itself and lastly factors related to the occlusion

description: The quantum adversary method is one of the most successful techniques for proving lower bounds on quantum query complexity. It gives optimal lower bounds for many problems, has application to classical complexity in formula size lower bounds, and is versatile with equivalent formulations in terms of weight schemes, eigenvalues, and Kolmogorov complexity. All these formulations rely on the principle that if an algorithm successfully computes a function then, in particular, it is able to distinguish between inputs which map to different values. We present a stronger version of the adversary method which goes beyond this principle to make explicit use of the stronger condition that the algorithm actually computes the function. This new method, which we call ADV+-, has all the advantages of the old: it is a lower bound on bounded-error quantum query complexity, its square is a lower bound on formula size, and it behaves well with respect to function composition. Moreover ADV+- is always at least as large as the adversary method ADV, and we show an example of a monotone function for which ADV+-(f)=Omega(ADV(f)^1.098). We also give examples showing that ADV+- does not face limitations of ADV like the certificate complexity barrier and the property testing barrier.

description: Radio relics are elongated sources related to shocks driven by galaxy cluster merger events. Although these objects are highly polarized at GHz frequencies ($\gtrsim 20\%$), high-resolution studies of their polarization properties are still lacking. We present the first high-resolution and high-sensitivity polarimetry study of the merging galaxy cluster CIZA J2242.8+5301 in the 1-4 GHz frequency band. We use the $QU$-fitting approach to model the Stokes $I$, $Q$ and $U$ emission, obtaining best-fit intrinsic polarization fraction ($p_0$), intrinsic polarization angle ($χ_0$), Rotation Measure (RM) and wavelength-dependent depolarization ($σ_{\rm RM}$) maps of the cluster. Our analysis focuses on the northern relic (RN). For the first time in a radio relic, we observe a decreasing polarization fraction in the downstream region. Our findings are possibly explained by geometrical projections and/or by decreasing of the magnetic field anisotropy towards the cluster center. From the amount of depolarization of the only detected background radio galaxy, we estimate a turbulent magnetic field strength of $B_{\rm turb}\sim5.6~μ$Gauss in the relic. Finally, we observe Rotation Measure fluctuations of about 30 rad m$^{-2}$ around at the median value of 140.8 rad m$^{-2}$ at the relic position.

description: The current postgraduate paper is an annotated translation of excerpts of the 6th chapter from the book Invisible women: Exposing Data Bias in a World Designed for Men by Caroline Criado Perez from English into Greek. The writer brings together for the first time an impressive range of case studies, stories and new research from across the world that illustrate how the bias scientific data form a society that excludes women and make them invisible. The translated excerpts reveal the data gap about their occupational health and the impact this has on their health and well-being. Initially, the text is examined according to Katharina Reiss's text analysis followed by the presentation of the theoretical framework concerning feminist translation, linguistic sexism and gender representation in the Greek language. Then, the original text is presented opposite of its translation, followed by the glossary and the terminology documentation. The textual and linguistic analysis of the original text comes next accompanied with the presentation of the research methodology. Furthermore, there is an analysis of the translation difficulties encountered in the text on a lexical, morphosyntactic, pragmatic and stylistic level along with the way they were addressed. Finally, the annex, provides a sample of an ad hoc text corpora that helped decoding the terminology and phraseology of the subject fields.
