description: Two of the most pressing questions in physics are the microscopic nature of the dark matter that comprises 84% of the mass in the universe and the absence of a neutron electric dipole moment. These questions would be resolved by the existence of a hypothetical particle known as the quantum chromodynamics (QCD) axion. In this work, we probe the hypothesis that axions constitute dark matter, using the ABRACADABRA-10cm experiment in a broadband configuration, with world-leading sensitivity. We find no significant evidence for axions, and we present 95% upper limits on the axion-photon coupling down to the world-leading level $g_{aγγ}<3.2 \times10^{-11}$ GeV$^{-1}$, representing one of the most sensitive searches for axions in the 0.41 - 8.27 neV mass range. Our work paves a direct path for future experiments capable of confirming or excluding the hypothesis that dark matter is a QCD axion in the mass range motivated by String Theory and Grand Unified Theories.

description: Mistrustful cryptography includes important tasks like bit commitment, oblivious transfer, coin flipping, secure computations, position authentication, digital signatures and secure unforgeable tokens. Practical quantum implementations presently use photonic setups. In many such implementations, Alice sends photon pulses encoding quantum states and Bob chooses measurements on these states. In practice, Bob generally uses single photon threshold detectors, which cannot distinguish the number of photons in detected pulses. Also, losses and other imperfections require Bob to report the detected pulses. Thus, malicious Alice can send and track multiphoton pulses and thereby gain information about Bob's measurement choices, violating the protocols' security. Here, we provide a theoretical framework for analysing such multiphoton attacks, and present known and new attacks. We illustrate the power of these attacks with an experiment, and study their application to earlier experimental demonstrations of mistrustful quantum cryptography. We analyse countermeasures based on selective reporting and prove them inadequate. We also discuss side-channel attacks where Alice controls further degrees of freedom or sends other physical systems.

description: The aim of the present thesis was the study of the trends towards the Greek picture book for children and its progress during the first decade of the 21st century. We examined the meaning of picture book, its functions, its progress of the previous decades and what is happening today with this kind of book in the Greek publishing area. Moreover, we analyzed the role of the image and its basic technical characteristics, the relationship between image and text as while as its independent readability. Furthermore, it was done a retrospect of the history of picture book in general and especially in the Greek area. We also searched the characteristics that a contemporary illustrator should have. Finally, we studied three cases of the contemporary Greek picture book for children and it was analyzed their illustration. Subsequently, we deduced some results about the trends that are prevailed in illustration at the beginning of the century we live

description: In prerecombination resolutions of the Hubble tension, such as early dark energy, new physics before recombination shifts the values of relevant cosmological parameters so that the models can fit with cosmic microwave background and baryon acoustic oscillations observations as well as $Λ$CDM does. In this paper, we clarify how the parameter shifts are related with $δH_0$, particularly we find the shift of primordial scalar spectral index scales as ${δn_s}\simeq 0.4{δH_0\over H_0}$ by performing the Monte Carlo Markov chain analysis with the Planck2018+BAO+Pantheon+R19+Keck Array/BICEP dataset. A novel point of our result is that if the current $H_0$ measured locally is correct, complete resolution of the Hubble tension seems to be pointing to a scale invariant Harrison-Zeldovich spectrum, i.e. $n_s= 1$ for $H_0\sim 73$km/s/Mpc.

description: We study the magnetic properties of two types of one dimensional XX spin 1/2 chains. The first type has only nearest neighbor interactions which can be either antiferromagnetic or ferromagnetic and the second type which has both nearest neighbor and next nearest neighbor interactions, but only antiferromagnetic in character. We study these systems in the presence of low transverse magnetic fields both analytically and numerically. Comparison of results show a close relation between the two systems, which is in agreement with results previously found in Heisenberg chains by means of a numerical real space renormalization group procedure.

Στο πρόγραμμα συμμετείχαν 48 άτομα ηλικίας 66-87 ετών με Ήπια Νοητική Εξασθένιση (ΗΝΕ) από την Ελληνική Εταιρεία Νόσου Alzheimer και Συγγενών Διαταραχών, εκ των οποίων 28 αποτελούσαν μέλη της ομάδας παρέμβασης και οι υπόλοιποι 20 μέλη της ομάδας ελέγχου. Η παρέμβαση ήταν διάρκειας 8 εβδομάδων, από μιάμιση ώρα την εβδομάδα και πραγματοποιήθηκε στους χώρους της εταιρείας Alzheimer. Πραγματοποιήθηκαν μετρήσεις στην ικανότητα κατανόησης και ερμηνείας μη κυριολεκτικού λόγου και έργα αξιολόγησης γνωστικής ευελιξίας και αναστολής των ατόμων της ομάδας ελέγχου και της ομάδας παρέμβασης πριν, αμέσως μετά και ένα μήνα μετά την παρέμβαση. Η μεικτή ανάλυση διακύμανσης (Mixed ANOVA)με ανεξάρτητες μεταβλητές την ομάδα (δι-υποκειμενική: πειραματική – ελέγχου) και τον χρόνο μέτρησης (ενδο-υποκειμενική: πριν, μετά τη παρέμβαση και follow up) δεν έδειξε διαφορές ανάμεσα στις δυο ομάδες, αλλά βελτίωση και των δυο ομάδων στα περισσότερα έργα στην δεύτερη και τρίτη μέτρηση. Πιθανολογούμε ότι αυτή η βελτίωση ήταν αποτέλεσμα της εξάσκησης στην οποία υπόκεινταν όλοι οι συμμετέχοντες κατα τις μετρήσεις. Επίσης, φαίνεται να υπάρχει σχέση στην απόδοση τους στα έργα κατανόησης του μη κυριολεκτικού λόγου με την απόδοση στα έργα γνωστικής ευελιξίας και αναστολής
description: The aim of the present thesis was the study of an intervention program in understanding and explaining the meaning of non literal language by patients with Mild Cognitive Impairment(MCI). In the study participated 48 patients with MCI aged 66-87 years old from Greek Association of Alzheimer’s Disease and Related Disorders (Alzheimer Hellas). The intervention group was consisted by 28 patients and control group by 20 patients. The intervention was 8 weeks long, one and a half hour per week and it took place in the Greek Association of Alzheimer’s disease. The participants were put through evaluations about the understanding and interpreting non literal language and through test for cognitive flexibility and inhibition, before, right after and one month later the intervention. Mixed ANOVA with independent variables the group (intervention groupcontrol group) and the time of the evaluations (before, after and follow up) did not appear differences between two groups, but improvement of both groups in the most evaluation tests. We suppose that this improvement is a result of the practice that they have been through through the evaluations. Also, there is correlation between the output of the measures of non literal language and the output of the measures of executive control

description: We analyse the recently measured $v_2$ fluctuation in the context of establishing the degree of fluidity of the matter produced in heavy ion collisions. We argue that flow observables within systems with a non-negligible mean free path should acquire a "dynamical" fluctuation, due to the random nature of each collision between the system's degrees of freedom. Because of this, $v_2$ fluctuations can be used to estimate the Knudsen number of the system produced at RHIC. To illustrate this quantitatively, we apply the UrQMD model, with scaled cross sections, to show that collisions at RHIC have a Knudsen number at least one order of magnitude above the expected value for an interacting hadron gas. Furthermore, we argue that the Knudsen number is also bound from above by the $v_2$ fluctuation data, because too large a Knudsen number would break the observed scaling of $v_2$ fluctuations due to the onset of turbulent flow. We propose, therefore that $v_2$ fluctuation measurements, together with an understanding of the turbulent regime for relativistic hydrodynamics, will provide an upper as well as a lower limit for the Knudsen number.

A Life Course Analysis of the Relationship Between Military Service and Criminal Behavior
Creators: name: Allen, Leana Cristine
Publisher: name: Digital Repository at the University of Maryland
Year: 2000

description: Throughout U.S. history, the military has served as one of the largest employers and educators of young men and women. As such, it has had a great influence in the lives of a large proportion of the U.S. population. Despite the potential impact of military service in later life, little research attention has focused on this topic, particularly in criminology. The few studies that have examined the relationship between military service and criminal behavior tend to have ignored pre-military characteristics, and results vary depending on the time period during which the sample served in the military. This study applies a life course framework to the question of how military service influences later criminal behavior. The main purpose of this research is to determine whether military service changes existing trajectories of criminal behavior and/or whether the military provides another setting for the continuation of pre-military behavior patterns. Other important considerations include selection into the military, the timing of military service in an individual's life, and the historical context of service. For example, do those who enter the military at an earlier age experience greater change in criminal behavior than those who enter later in life? Additionally, does the influence of military service on criminal behavior differ by historical context? To address these questions, this study uses four data sets; three birth cohorts (1942, 1945, and 1949) and the National Longitudinal Survey of Youth. Men in these samples served during different historical periods from the beginning of the Vietnam War to the early period of the all-volunteer force. Statistical methods were used to account for potential differences in selection and the presence of unobserved heterogeneity. Results suggest that there is an important influence of military service on later criminal behavior, but the specific direction of the effect depends on the historical period in which service occurred. In particular, serving in the military during the Vietnam era was related to reduced offending, and service during the volunteer era was related to increased offending. These results were significant even after controlling for race, education, socioeconomic status, age, and prior criminal behavior patterns.
Native Students in a Community College: Perceptions of Upgrading and Career Students

description: A 59-item questionnaire dealing with aspects of self-preparation, campus life, rela­tionships with families, and satisfaction with programs was administered to stu­ dents in three kinds of programs at a community college—upgrading programs, a career program that included an upgrading component, and a career program re­ quiring upgrading before entry. The questionnaire was administered in fall and spring of one academic year and the responses of Native students were compared between programs. The results of grouped and paired t-tests appropriate to the specific comparison, as well as responses to open-ended questionnaire items, indi­ cate somewhat different patterns of changing perception between groups over the course of the program. The study produced a working hypothesis for further study, that programs that combine career programs with upgrading, rather than requiring upgrading before entry, enhance students' self-esteem.

Οι σησαμόσποροι υποβλήθηκαν σε δύο διαφορετικές θερμικές κατεργασίες (φρύξη και εμβάπτιση σε θερμό νερό). Οι αφριστικές ιδιότητες των εκχυλισμάτων συγκρίθηκαν με αυτές του αγελαδινού γάλακτος και ενός εμπορικού ροφήματος σόγιας, τα οποία χρησιμοποιούνται από επαγγελματίες για την παρασκευή αφρών. Επιπλέον, μελετήθηκε η επίδραση της προσθήκης κόμμεων ή απομάκρυνσης μέρους του ελαίου ή των στερεών στις αφριστικές ιδιότητες των εκχυλισμάτων. Σύμφωνα με τα αποτελέσματα που προέκυψαν, η προκατεργασία με φρύξη ενίσχυσε την αφριστική ικανότητα των εκχυλισμάτων σησαμόσπορων σε σύγκριση με αυτήν της εμβάπτισης σε θερμό νερό. Η απομάκρυνση μέρους του ελαίου και η προσθήκη ξανθάνης βελτίωσαν τις αφριστικές ιδιότητες των εκχυλισμάτων, ενώ η απομάκρυνση μέρους των στερεών και η προσθήκη κόμμεως γκουάρ και ι-καραγεννάνης τις περιόρισαν ή δεν τις μετέβαλαν σημαντικά. Τα εκχυλίσματα σησαμόσπορων εμφάνισαν ικανοποιητική αφριστική δράση συγκρίσιμη με αυτή του εμπορικού ροφήματος σόγιας, αλλά υποδεέστερη του αγελαδινού γάλακτος, η οποία ενισχύθηκε μετά από κατάλληλες τροποποιήσεις της σύστασής τους (μείωση του μέγεθους των ελαιοσωμάτων με επαρκή ομογενοποίηση, απομάκρυνση μέρους του ελαίου, προσθήκη κόμμεως ξανθάνης).
description: The aim of this study was the preparation and verification of the composition and quality characteristics of sesame seed aqueous extracts and the study of their foaming properties at two temperatures (65 and 4 °C). Sesame seeds were previously subjected to either roasting or blanching and the foaming properties of the obtained sesame seed extracts were compared with those of cow milk and a commercial soy beverage. The effect of partial oil or solids removal as well as the addition of gums on the foaming properties of sesame seed extracts was also studied. In general, the extracts obtained after sesame seed blanching presented inferior foaming properties in comparison to the roasted ones. Furthermore, partial oil removal and xanthan gum addition led to an improvement of the foaming capacity and foam characteristics, while partial solids removal and the addition οf guar gum and ι-carrageenan gum either reduced or did not significantly affect them. Sesame seed extracts presented satisfactory foaming behavior comparable to that of soy beverage, but minor to that of cow milk, which could be enhanced by reducing the oleosomes size with adequate homogenization, removing part of the oil and adding xanthan gum.

description: The purpose of this thesis was to identify the pedagogical principles in the texts of the Catechetical Homilies of Saint Theodore Studites. We first referred to the importance, prehistory and history of catechism in the life of the Orthodox Church. Then, as one of the main representatives of the catechist tradition, we presented in detail the figure of St. Theodore of Studios. We have outlined his personality as an Abbot and Teacher at the Monastery of Stoudiou. The main purpose of this dissertation was to find passages in the Great and Small Catecheses that demonstrate the use of basic pedagogical and didactic principles by the Saint and to reveal his teaching methodology.

description: We model the formation, evolution and astrophysical effects of dark compact Scalar Miniclusters (``ScaMs''). These objects arise when a scalar field, with an axion-like or Higgs-like potential, undergoes a second order phase transition below the QCD scale. Such a scalar field may couple too weakly to the standard model to be detectable directly through particle interactions, but may still be detectable by gravitational effects, such as lensing and baryon accretion by large, gravitationally bound miniclusters. The masses of these objects are shown to be constrained by the Ly$α$ power spectrum to be less than $\sim 10^4 M_\odot$, but they may be as light as classical axion miniclusters, of the order of $10^{-12} M_\odot$. We simulate the formation and nonlinear gravitational collapse of these objects around matter-radiation equality using an N-body code, estimate their gravitational lensing properties, and assess the feasibility of studying them using current and future lensing experiments. Future MACHO-type variability surveys of many background sources can reveal either high-amplification, strong lensing events, or measure density profiles directly via weak-lensing variability, depending on ScaM parameters and survey depth. However, ScaMs, due to their low internal densities, are unlikely to be responsible for apparent MACHO events already detected in the Galactic halo. A simple estimate is made of parameters that would give rise to early structure formation; in principle, early stellar collapse could be triggered by ScaMs as early as recombination, and significantly affect cosmic reionization.

We find that in the range favored by electroweak baryogenesis ({\it i.e.,} $|μ|\simeq M_1$ or $|μ|\simeq M_2$), $\sin [θ_μ+θ_{M_1}]$ can be as large as ${\cal O}(1)$, even for slepton masses below 500 GeV. Such large values of the phases promise a successful electroweak baryogenesis. We also discuss the possibility of large CP-odd effects at a linear collider.

description: We present a systematic analysis of all the BeppoSAX data of SGR1900+14. The observations spanning five years show that the source was brighter than usual on two occasions: ~20 days after the August 1998 giant flare and during the 10^5 s long X-ray afterglow following the April 2001 intermediate flare. In the latter case, we explore the possibility of describing the observed short term spectral evolution only with a change of the temperature of the blackbody component. In the only BeppoSAX observation performed before the giant flare, the spectrum of the SGR1900+14 persistent emission was significantly harder and detected also above 10 keV with the PDS instrument. In the last BeppoSAX observation (April 2002) the flux was at least a factor 1.2 below the historical level, suggesting that the source was entering a quiescent period.

description: The aim of the present thesis is the study of consumer behavior and its aspects towards probiotics. In this thesis is examined the level of knowledge, the perceptions and the consumer behavior, as regards probiotics. At the beginning there is a detailed description of the consumer behavior theory, with particular emphasis on the elements that influence it and the importance of its study. Then follows an extensive review of the literature on published research from around the world which is related to functional and probiotic foods, consumer behavior towards different parts of the world, their health benefits and the legal provisions governing them. Furthermore, is presented the quantitative survey based on primary data which was conducted through direct interviews, for the most part. For the research needs, a structured questionnaire of twenty questions was applied to three hundred and sixty adult consumers in Thessaloniki's urban complex, during the period January 2017 - September 2018. In the context of the results' processing, the questionnaire was verified and validated, followed by descriptive statistical analysis and categorical regression through the IBM SPSS Statistics 25.0 statistical program. Finally, the results are presented and being discussed

description: We investigate the dynamics of an idealized model of microtubule growth that evolves by: (i) attachment of guanosine triphosphate (GTP) at rate lambda, (ii) conversion of GTP to guanosine diphosphate (GDP) at rate 1, and (iii) detachment of GDP at rate mu. As a function of these rates, a microtubule can grow steadily or its length can fluctuate wildly. For mu=0, we find the exact tubule and GTP cap length distributions, and power-law length distributions of GTP and GDP islands. For mu=infinity, we argue that the time between catastrophes, where the microtubule shrinks to zero length, scales as exp(lambda). We also find the phase boundary between a growing and shrinking microtubule.

Enhancing Aboriginal Teacher Education: One Promising Approach
Creators: name: Ralph, Edwin G.
Publisher: name: Canadian Journal of Native Education
Year: 2021

description: The preservice preparation of Aboriginal teachers has grown in importance in Saskatchewan in recent years. This study describes how one extended practician supervisor with the University of Saskatchewan used the Contextual Supervision (CS) model during his internship duties with several Aboriginal teacher interns and their cooperating teachers. The purpose of his application of CS was to assess its effectiveness and to validate its actual use, in that context. The findings, con­sistent with evidence accumulating from a modest number of studies of CS, sug­ gest that the model has definite potential to improve the supervisory process with Aboriginal neophyte teachers.

Toward Community: The Community School Model and the Health of Sovereignty
Creators: name: Calliou, Sharilyn
Publisher: name: Canadian Journal of Native Education
Year: 2021

description: First Nations are in the process of reasserting unique locally responsive forms of sovereignty. Schooling in this time of transition requires talented lay and professional educators who are aware of language, culture, and effective teaching strategies. They will need to be aware of the role of the school in the creation of healthy communities, as healthy communal living is one foundational element in the formation of stable self-government. This article is intended to provide a cross-cultural exploration of the concept of community and of seven features of a com­munity school model based on an analysis of 30 selections written by community education theorists.

High density animal cell culture systems using porous supports
Creators: name: Lee, Daniel W.
Publisher: name: University of British Columbia
Year: 2008

description: Monolithic porous ceramic and porous polystyrene microcarriers were examined as supports for large scale mammalian cell culture. Vero cells and transformed baby hamster kidney (BHK) cells which produced human transferrin were grown in three different reactor configurations: a fixed bed ceramic perfusion system, an airlift systemwith draft tube made of porous ceramic and a stirred tank configuration which used porous polystyrene microcarriers. The porous matrices provide an increased surface area for cell attachment and growth and protect the entrapped or immobilized cells from shear stress in the bulk fluid. Steady state cell concentrations in all three systems were found to be in excess of 108 cells per mL porous matrix. All three systems intensified the culture process by increased cell mass per unit volume — a minimum five—fold increase in reactor volumetric cell density over simple suspension cultures. The airlift and microcarrier stirred tank system offer the potential to scale—up by increasing reactor volume. The fixed bed ceramic perfusion system can be used as a cell propagator to produce the required inoculum for other large scale bioreactors. Unlike the Opticore of the Opticell systems, the ceramic foam element can be reused. Its multiple interconnected channel structure greatly reduces the possibility of channel blockage due to over—grown cells. The biologically inert porous polystyrene microcarriers tested have distinct advantages, in terms of product purification, over the collagen based porous microcarriers such as Cultispher—G and Informatrix microcarriers. Cell attachment rates onto the porous polystyrene microcarriers treated with sulphuric acid were comparable to those of Cytodex-1 and Cultispher—G particles while the cell growth and productivity per unit carrier volume were 20% superior to the two tested commercial microcarriers. The use of airlift eliminates the need for a separate oxygenator or spin filter for gas exchange. The input gas created a differential pressure drop across the porous draft tube and forced the medium to perfuse through the porous draft tube. A simple mathematical model was formulated to describe the hydrodynamic behaviour of the porous draft tube airlift system. The model allows gas holdup, liquid superficial velocity, and liquid perfusion rate through the porous draft tube to be predicted for a given gas input. For the cases examined, the predictions are in satisfactory agreement with the overall trend of experimental measurements.
Full-wave finite-difference time-domain simulation of electromagnetic cloaking structures

description: This paper proposes a radial dependent dispersive finite-difference time-domain method for the modelling of electromagnetic cloaking structures. The permittivity and permeability of the cloak are mapped to the Drude dispersion model and taken into account in dispersive FDTD simulations. Numerical simulations demonstrate that under ideal conditions, objects placed inside the cloak are `invisible' to external electromagnetic fields. However for the simplified cloak based on linear transformations, the back scattering has a similar level to the case of a PEC cylinder without any cloak, rendering the object still being `visible'. It is also demonstrated numerically that the simplified cloak based on high-order transformations can indeed improve the cloaking performance.

description: This thesis presents techniques to design control laws for nonlinear dynamical systems, based on Lyapunov functions. First of all, we introduce some preliminary concepts from the theory of dynamical systems such as the flow and the notion of equilibrium point. Also, we present the theorem of local existence and uniqueness of a solution to a differential equation. Then, we present the basics of Lyapunov’s stability theory. We start by defining what stable, asymptotically stable and unstable equilibrium point in the sense of Lyapunov are. Furthermore, we prove the following theorems: Lyapunov’s, about the stability of an equilibrium point from a Lyapunov function, Cheatev’s theorem about instability, LaSalle’s principle for asymptotic stability with fewer restrictions and lastly the converse Lyapunov theorem. In the latter part of the thesis, we introduce the Integrator Backstepping method, which uses a control Lyapunov function. The structure of the system we apply it to, means that we find a control Lyapunov function step by step and end up with an overall stabilizing control. However, this method is applicable only to specific classes of control systems, which we specify. Finally, we mention briefly a few applications of this technique in engineering problems
Electroweak standard model at finite temperature in presence of a bosonic chemical potential

description: We study the electroweak standard model at finite temperature in presence of a bosonic chemical potential associated with the conserved electromagnetic current. To preserve the thermodynamic equilibrium of the system, the thermal medium is neutralized by the introduction of four background charges related to the four gauge bosons of this model. Using the mean-field approximation, in the high temperature limit, we find that there exists a difference between the effective mass of the spatial and temporal components of the W boson. A W boson condensation induced via the background charges allows to vanish this difference.
