description: In this paper, we construct quantum invariants for knotoid diagrams in $\mathbb{R}^2$. The diagrams are arranged with respect to a given direction in the plane ({\it Morse knotoids}). A Morse knotoid diagram can be decomposed into basic elementary diagrams each of which is associated to a matrix that yields solutions of the quantum Yang-Baxter equation. We recover the bracket polynomial, and define the rotational bracket polynomial, the binary bracket polynomial, the Alexander polynomial, the generalized Alexander polynomial and an infinity of specializations of the Homflypt polynomial for Morse knotoids via quantum state sum models.
Cross-cultural reentry stress: analysis of a group intervention using the critical incident technique

description: The cross-cultural adaptation process has been a focus of theoretical and practical interest in the field of cross-cultural counselling. Recently, interest has proceeded from the initial adaptation phase (culture shock) experienced by sojourners when leaving home to a focus on the reentry adaptation phase (reentry shock), experienced by sojourners who have returned home after extended stays abroad. Increasing numbers of Canadian sojourners are currently travelling in a wide variety of contexts and for a wide variety of purposes. Interest in reentry adaptation is fueled by a corresponding, accelerated demand for knowledge of factors influencing reentry adjustment and for interventions effective in reducing its' attendant stress. To date, cross-cultural reentry research has been informed primarily by methodologies (quantitative and anecdotal) that give an overview of the phenomenon but do not yield in-depth, systematic accounts of the lived experience of returnees, resulting in a dearth of information on interventions effective in assisting returnees with their readjustment. The purpose of this study was to (1) accumulate in-depth information about the reentry adjustment process from returnees whose experience had been amplified by a group-based reentry program, (2) analyze these data systematically, in order to identify factors, directly or indirectly related to the reentry program which appear to be facilitating and/or hindering to the reentry adjustment process, and (3) develop a framework of interventions which can be used by counsellors and others in the cross-cultural field to assist returnees in their readjustment process. A qualitative methodology was used in which two groups of returnees were interviewed during the period of late 1992 to mid 1994 after participating in 2-day, professional reentry workshops. Participant interviews were analyzed using The Critical Incident Technique in order to identify factors which influence reentry adjustment. The 19 interviewees were Canadian repatriates who had recently returned from business-related stays of 1 to 4 years' duration in Asia. A total of 245 critical incidents were derived from the 19 interviews. Out of these incidents, a scheme of 12 categories of factors, facilitative of reentry was developed. In order to ensure trustworthiness and soundness of categories, the category scheme was subjected to several tests of reliability and validity. Also identified were 2 emergent themes, separate and unrelated to the program, which related to occurrences of a hindering nature to reentry adjustment. Finally, antecedent factors related to the 245 facilitative critical incidents were identified. These latter findings resulted in the development of a framework of cross-cultural reentry interventions. Implications for theory development and future research; and applications for counselling in the area of cross-cultural reentry are explored.

description: Στις Νευροεπιστήμες η τεχνική εισαγωγής ηλεκτροδίων στον εξωκυττάριο ιστό του εγκεφάλου, με σκοπό την καταγραφή της δραστηριότητας μεμονωμένων νευρώνων (single-unit activity), είναι μία συνηθισμένη διαδικασία που έχει ως στόχο την μελέτη της λειτουργίας του εγκεφάλου, καθώς και διάφορων διαταραχών του όπως η παράλυση και η απώλεια μνήμης. Στην πραγματικότητα τα ηλεκτρόδια δεν καταγράφουν την δραστηριότητα ενός νευρώνα, αλλά περισσότερων.Για αυτό το λόγο είναι απαραίτητη η εφαρμογή του λεγόμενου spike sorting, έτσι ώστε να ανιχνευθούν και να ταξινομηθούν οι κορυφές που παράγουν οι νευρώνες, οι οποίες διαφέρουν ανάλογα με τα μορφολογικά τους χαρακτηριστικά.

Στο τέλος θα συγκριθούν τα αποτελέσματα των μοντέλων μεταξύ τους, καθώς και με τα αντίστοιχα της βιβλιογραφίας.

description: In Neuroscience, the technique of inserting an electrode into the extracellular brain tissue, in order to record the activity of individual neurons (single-unit activity), is a common procedure used in the study of the brain, as well as of some brain disorders like paralysis or memory loss. In reality the electrodes do not record the activity of a single neuron, but a group of neurons instead. Therefore, it is necessary to conduct the known spike sorting process. Spike sorting is a process of detection and classiﬁcation of the spikes, produced by neurons, that diﬀers in respect of their morphological features. In relevant literature, there are standard steps for the process of the neural spikes with ﬁnal goal their clustering. In present master thesis, we will apply the various techniques, for each step, in order to train some convolutional neural networks (CNNs). In the end, we will compare the results between the models, as well as with the results of the literature. It is important to point out that such an approach has never been applied till now, as far as we know

description: The structure and evolution of protoplanetary disks (PPDs) are largely governed by disk angular momentum transport, mediated by magnetic fields. In the most observable outer disk, PPD gas dynamics is primarily controlled by ambipolar diffusion as the dominant non-ideal magnetohydrodynamic (MHD) effect. In this work, we study the gas dynamics in outer PPDs by conducting a set of global 3D non-ideal MHD simulations with ambipolar diffusion and net poloidal magnetic flux, using the Athena++ MHD code, with resolution comparable to local simulations. Our simulations demonstrate the co-existence of magnetized disk wind and turbulence driven by the magneto-rotational instability (MRI). While MHD wind dominates disk angular momentum transport, the MRI turbulence also contributes significantly. We observe that magnetic flux spontaneously concentrate into axisymmetric flux sheets, leading to radial variations in turbulence levels, stresses, and accretion rates. Annular substructures arise as a natural consequence of magnetic flux concentration. The flux concentration phenomena show diverse properties with different levels of disk magnetization and ambipolar diffusion. The disk generally loses magnetic flux over time, though flux sheets could prevent the leak of magnetic flux in some cases. Our results demonstrate the ubiquity of disk annular substructures in weakly MRI turbulent outer PPDs, and imply a stochastic nature of disk evolution.

description: The aim of the present thesis was the study of communication strategies of two completely different groups, one of the hacktivist group of Anonymous and the terrorist group of ISIS. We examined each group separately and we tried to expose both the differences and the similarities, especially in the way each group tries to communicate its message to its audience, but also to influence it. Then, taking into account the digital age we live in, and considering that these groups have emerged during this age, we have looked into the contribution and the important role of the Internet, and by extension of the New Media (Social Media), to those communication campaigns. Furthermore, recognizing the importance of the image in a “visual culture”, and also emphasizing it as a key element for both communication campaigns, we referred to its qualities, and also to its ability, if presented within a specific context, to influence, in A degree, the viewer's judgment. Finally, and since we looked into the role played by the journalist world and the way it seems to be dealing with such news, we have quoted the interviews of two noteworthy journalists, aware of the issue, in order to get the "inner" view of two specialists, but also in order to ensure the correctness of our conclusions.

description: It is known from the literature that CGRP plays an important role in migraine and antagonizing CGRP is an effective preventing treatment against migraine pain. CGRP is able to increase neuronal excitability. Further it has been shown that a CSD - that is known to be the correlate of the migraine aura - can release CGRP in rat neocortical slices. Whether CGRP enhances brain’s susceptibility for CSD or influence CSD itself in vivo has not been investigated yet. To test this, we applied CGRP at different concentrations topically to a restricted part of the cortical surface and compared the electrocorticogram, regional cerebral blood flow (rCBF) and parameters of CSD in the treated region with the untreated brain area. In spontaneously breathing anesthetized adult rats (sodium thiopentone, 100 mg/kg, i.p.) CSDs were recorded in cerebral cortex with two pairs of glass micropipettes (distance 5-6 mm) at depths of 400 and 1200 µm in two areas of the cortex, separated by a wall. In addition, in the treated area CSD-related changes in extracellular potassium concentration ([K+]e) were measured with a micropipette filled with Corning IE-190 ionic exchanger. In the untreated area, CSD was elicited by a microinjection of 1 M KCl (100 kPa, 300 ms up to 1 s, depth 1200 µm) into the grey matter at intervals of 30 min. In the remote area 100 µl of CGRP at concentrations from 10-8 M to 10-5 M (only one concentration per experiment) were applied topically and left there for three hours. In both cortical areas rCBF was measured. In all rats tested, a pulse of KCl elicited a single propagating CSD. The topical application of CGRP to the brain surface reduced the amplitudes of CSD in the treated area (10-5 M to 60 % of controls; 10-8 M to 70 % of controls; untreated to 85-90 % of controls) and slowed the propagation velocity (10-5 M from 3.0 to 2.6 cm/s; 10-8 M from 2.4 to 2.2 cm/s). Rarely spontaneous CSD were observed originating from the CGRP-treated area. In another few rats, CGRP induced focal ictal activity after 2-3 hours of application that did not spread into the untreated cortex. Focal ictal activity occurred at intervals of 8-10 min and was accompanied by transient increases in [K+]e. However, so far neither the ignition of CSDs nor the induction of focal ictal activity showed a dose-dependency to CGRP. Our results identify the neuropeptide CGRP as a candidate that could interfere with CSD by changing neuronal excitability.

description: The position of the Sun inside the Milky Way's disc hampers the study of the spiral arm structure. We aim to analyse the spiral arms along the line-of-sight towards the Galactic centre (GC) to determine their distance, extinction, and stellar population. We use the GALACTICNUCLEUS survey, a JHKs high angular resolution photometric catalogue (0.2") for the innermost regions of the Galaxy. We fitted simple synthetic colour-magnitude models to our data via $χ^2$ minimisation. We computed the distance and extinction to the detected spiral arms. We also analysed the extinction curve and the relative extinction between the detected features. Finally, we built extinction-corrected Ks luminosity functions (KLFs) to study the stellar populations present in the second and third spiral arm features. We determined the mean distances to the spiral arms: $d1=1.6\pm0.2$, $d2=2.6\pm0.2$, $d3=3.9\pm0.3$, and $d4=4.5\pm0.2$ kpc, and the mean extinctions: $A_{H1}=0.35\pm0.08$, $A_{H2}=0.77\pm0.08$, $A_{H3}=1.68\pm0.08$, and $A_{H4}=2.30\pm0.08$ mag. We analysed the extinction curve in the near infrared for the stars in the spiral arms and found mean values of $A_J/A_{H}=1.89\pm0.11$ and $A_H/A_{K_s}=1.86\pm0.11$, in agreement with the results obtained for the GC. This implies that the shape of the extinction curve does not depend on distance or absolute extinction. We also built extinction maps for each spiral arm and obtained that they are homogeneous and might correspond to independent extinction layers. Finally, analysing the KLFs from the second and the third spiral arms, we found that they have similar stellar populations. We obtained two main episodes of star formation: $>6$ Gyr ($\sim60-70\%$ of the stellar mass), and $1.5-4$ Gyr ($\sim20-30\%$ of the stellar mass), compatible with previous work. We also detected recent star formation at a lower level ($\sim10\%$) for the third spiral arm.

description: We analyze the behavior of an ensemble of inertial particles in a one-dimensional smooth Gaussian velocity field, in the limit of large inertia, but considering a finite correlation time for the random field. We derive in this limit a perturbative scheme for the calculation of the concentration correlation and of the particle relative velocity distribution, providing analytical expressions for the concentration fluctuation amplitude, its correlation length, and the modification in the particle pair relative velocity variance. The amplitude of the concentration fluctuations is characterized by slow decay at large inertia and a much larger correlation length than that of the random field. The fluctuation structure in velocity space is very different from predictions from short-time correlated random velocity fields, with only few particle pairs crossing at sufficiently small relative velocity to produce correlations. Concentration fluctuations are associated with depletion of the relative velocity variance of colliding particles.

description: This paper presents a novel robot-environment interaction in navigation tasks such that robots have neither a representation of their working space nor planning function, instead, an active environment takes charge of these aspects. This is realized by spatially deploying computing units, called cells, and making cells manage traffic in their respective physical region. Different from stigmegic approaches, cells interact with each other to manage environmental information and to construct instructions on how robots move. As a proof-of-concept, we present an architecture called AFADA and its prototype, consisting of modular cells and robots moving on the cells. The instructions from cells are based on a distributed routing algorithm and a reservation protocol. We demonstrate that AFADA achieves efficient robot moves for single-robot navigation in a dynamic environment changing its topology with a stochastic model, comparing to self-navigation by a robot itself. This is followed by several demos, including multi-robot navigation, highlighting the power of offloading both representation and planning from robots to the environment. We expect that the concept of AFADA contributes to developing the infrastructure for multiple robots because it can engage online and lifelong planning and execution.

description: Spontaneous symmetry breaking is the foundation of electroweak unification and serves as an integral part of the model building beyond the standard model of particle physics and it also finds interesting applications in the late Universe. We review development related to obtaining the late cosmic acceleration from spontaneous symmetry breaking in the Universe at large scales. This phenomenon is best understood through Ginzburg-Landau theory of phase transitions which we briefly describe. Hereafter, we present elements of spontaneous symmetry breaking in relativistic field theory. We then discuss the "symmetron" scenario-based upon symmetry breaking in the late Universe which is realized by using a specific form of conformal coupling. However, the model is faced with "NO GO" for late time acceleration due to local gravity constraints. We argue that the problem can be circumvented by using the massless $λϕ^4$ theory coupled to massive neutrino matter. As for the early Universe, spontaneous symmetry breaking finds its interesting applications in the study of electroweak phase transition. To this effect, we first discuss in detail, the Ginzburg-Landau theory of first order phase transitions and then apply it to electroweak phase transition including technical discussions on bubble nucleation and sphaleron transitions. We provide a pedagogical expositions of dynamics of electroweak phase transition and emphasize the need to go beyond the standard model of particle physics for addressing the baryogenesis problem. Review ends with a brief discussion on Affleck-Dine mechanism and spontaneous baryogenesis. Appendixes include technical details on essential ingredients of baryogenesis, sphaleron solution, one loop finite temperature effective potential and dynamics of bubble nucleation.

description: Differentially pumped capillaries, i.e., capillaries operated in a pressure gradient environment, are widely used for nonlinear pulse compression. In this work, we show that strong pressure gradients and high gas throughputs can cause spatiotemporal instabilities of the output beam profile. The instabilities occur with a sudden onset as the flow evolves from laminar to turbulent. Based on the experimental and numerical results, we derive guidelines to predict the onset of those instabilities and discuss possible applications in the context of nonlinear flow dynamics.
Examining normal modes as fundamental heat carriers in amorphous solids: the case of amorphous silicon

description: Normal mode decomposition of atomic vibrations has been used to provide microscopic under-standing of thermal transport in amorphous solids for decades. In normal mode methods, it is naturally assumed that atoms vibrate around their equilibrium positions and that individual normal modes are the fundamental vibrational excitations transporting heat. With the abundance of predictions from normal mode methods and experimental measurements now available, we care-fully analyze these calculations in amorphous silicon, a model amorphous solid. We find a number of discrepancies, suggesting that treating individual normal modes as fundamental heat carriers may not be accurate in amorphous solids. Further, our classical and ab-initio molecular dynamics simulations of amorphous silicon demonstrate a large degree of atomic diffusion, especially at high temperatures, leading to the conclusion that thermal transport in amorphous solids could be better described starting from the perspective of liquid dynamics rather than from crystalline solids

description: This MA dissertation attempts to investigate the origin, the personality as well as the social, religious and political activity of two women, augustai in the Byzantine iconoclast era, Irene of Athens and Theodora. Moreover we explore the conditions, under which both were called upon to rule as regents for their underage sons, Constantine V and Michael III, respectively. We also examine the working conditions and the conclusions of the Seventh Ecumenical Council of 787 and the Synod of 843. In addition, we refer to the leading role that these two empresses, Irene and Theodora, played in the work of two aforementioned Councils and in peacefully restoring icon-worship. The cohesive tissue underlying the entire study is the iconoclastic era (726-843) starting from the reign of Leo III the Isaurian, with a view to better illuminating the historical context in which these two empresses were called upon to rule.

description: We calculate the critical power for collapse of linearly-polarized phase vortices, and show that this expression is more accurate than previous results. Unlike the non-vortex case, deviations from radial symmetry do not increase the critical power for collapse, but rather lead to disintegration into collapsing non-vortex filaments. The cases of circular, radial and azimuthal polarizations are also considered.

description: The next-generation, broadband geodetic very long baseline interferometry system, named VGOS, is developing its global network, and VGOS networks with a small size of 3--7 stations have already made broadband observations from 2017 to 2019. We made quality assessments for two kinds of observables in the 21 VGOS sessions currently available: group delay and differential total electron content ($δ$TEC). Our study reveals that the random measurement noise of VGOS group delays is at the level of less than 2 ps (1 ps = 10$^{-12}$ s), while the contributions from systematic error sources, mainly source structure related, are at the level of 20 ps. Due to the significant improvement in measurement noise, source structure effects with relatively small magnitudes that are not overwhelming in the S/X VLBI system, for instance 10 ps, are clearly visible in VGOS observations. Another critical error source in VGOS observations is discrete delay jumps, for instance, a systematic offset of about 310 ps or integer multiples of that. The predominant causative factor is found to be related to source structure. The measurement noise level of $δ$TEC observables is about 0.07 TECU, but the systematic effects are five times larger than that. A strong correlation between group delay and $δ$TEC observables is discovered with a trend of 40 ps/TECU for observations with large structure effects; there is a second trend in the range 60 ps/TECU to 70 ps/TECU when the measurement noise is dominant.

description: We develop a chiral symmetric relativistic mean field model with logarithmic sigma potential derived in the strong coupling limit of the lattice QCD. We find that both of the nuclear matter and finite nuclei are well described in the present model. The normal vacuum is found to have global stability at zero and finite baryon densities, and an equation of state with moderate stiffness (K ~ 280 MeV) is obtained. The binding energies and charge radii of Z closed even-even nuclei are well reproduced in a wide mass range from C to Pb isotopes, except for the underestimates of binding energies in several jj closed nuclei.

description: Factors which may be critical to the success of children's anger management programs remain largely uninvestigated. Accordingly an exploratory study was undertaken to describe some of these factors, personal and situational, as observed during the implementation of a school program on anger management. Fifty-eight students (28 males and 30 females) in grades 5, 6, and 7 (ages 10.75 to 14.0 years) participated in a 6-lesson guidance unit on anger management. The unit consisted of a didactic component, covering cognitive-behavioural anger management techniques, and an art component, promoting exploration and expression of anger-related affect through painting. The two components occurred in a different sequence within the program for each half of the sample. Subjects provided data at the beginning, middle and end of the program on anger expression stylistics (Pediatric Anger Expression Scale), state and trait anger and anxiety (Pediatric Anger Scale and Pediatric Anxiety Scale), and knowledge of curriculum content (Anger Management Questionnaire). Subjects also completed the Children's Nowicki-Strickland Internal-External control scale. Independent raters assigned ratings for degree of anger and degree of defensiveness to each of the three paintings completed by each subject within the art component. Data analysis assessed the relationship between scores on the repeated measures and paintings and the following factors: the nature and sequence of program components and activities; and subject age, ability level, gender, and locus of control. In the second painting, subjects undergoing the art component first (art-first) expressed more anger (p < .05) than those doing the didactic component first (didactic-first), while on the third painting the latter were rated as more defensive (p < .01) than the former. The sample as a whole (p < .01) and both the art-first (p < .01) and didactic-first (p < .05) groups expressed more anger in the second painting than in either of the other two. Gender differences were found in state anger and knowledge of curriculum content at mid-program, and in degree of defensiveness on the first painting (all p < .05). External locus of control was associated at low levels with trait anxiety at mid-program and at the end, and with state anxiety at the end (all p < .05). Across the sample, trait anxiety was higher pre-program than at either the mid-point or the end (p < .05). State anger and state anxiety were substantially correlated (p < .01) on all three measurement occasions, although the range of the former measure was truncated due to floor effects. The results highlight the potential importance of the following factors: content and sequence of program components, nature of the relationship between instructor and students, and levels of state anger and state anxiety. Practical and research implications of the findings are discussed.

description: Narrow-line Seyfert 1 (NLS1) galaxies are a class of active galactic nuclei (AGN) that, in some cases, can harbor powerful relativistic jets. One of them, PKS 2004-447, shows gamma-ray emission, and underwent its first recorded multifrequency flare in 2019. However, past studies revealed that in radio this source can be classified as a compact steep-spectrum source (CSS), suggesting that, unlike other gamma-ray sources, the relativistic jets of PKS 2004-447 have a large inclination with respect to the line of sight. We present here a set of spectroscopic observations of this object, aimed at carefully measuring its black hole mass and Eddington ratio, determining the properties of its emission lines, and characterizing its long term variability. We find that the black hole mass is $(1.5\pm0.2)\times10^7$ M$_\odot$, and the Eddington ratio is 0.08. Both values are within the typical range of NLS1s. The spectra also suggest that the 2019 flare was caused mainly by the relativistic jet, while the accretion disk played a minor role during the event. In conclusion, we confirm that PKS 2004-447 is one of the rare examples of gamma-ray emitting CSS/NLS1s hybrid, and that these two classes of objects are likely connected in the framework of AGN evolution.

description: Recent transport measurements on thin graphite films grown on SiC show large coherence lengths and anomalous integer quantum Hall effects expected for isolated graphene sheets. This is the case eventhough the layer-substrate epitaxy of these films implies a strong interface bond that should induce perturbations in the graphene electronic structure. Our DFT calculations confirm this strong substrate-graphite bond in the first adsorbed carbon layer that prevents any graphitic electronic properties for this layer. However, the graphitic nature of the film is recovered by the second and third absorbed layers. This effect is seen in both the (0001)and $(000\bar{1})$ 4H SiC surfaces. We also present evidence of a charge transfer that depends on the interface geometry. It causes the graphene to be doped and gives rise to a gap opening at the Dirac point after 3 carbon layers are deposited in agreement with recent ARPES experiments (T.Ohta et al, Science {\bf 313} (2006) 951).

description: In many applications of multiple hypothesis testing where more than one false rejection can be tolerated, procedures controlling error rates measuring at least $k$ false rejections, instead of at least one, for some fixed $k\ge 1$ can potentially increase the ability of a procedure to detect false null hypotheses. The $k$-FWER, a generalized version of the usual familywise error rate (FWER), is such an error rate that has recently been introduced in the literature and procedures controlling it have been proposed. A further generalization of a result on the $k$-FWER is provided in this article. In addition, an alternative and less conservative notion of error rate, the $k$-FDR, is introduced in the same spirit as the $k$-FWER by generalizing the usual false discovery rate (FDR). A $k$-FWER procedure is constructed given any set of increasing constants by utilizing the $k$th order joint null distributions of the $p$-values without assuming any specific form of dependence among all the $p$-values. Procedures controlling the $k$-FDR are also developed by using the $k$th order joint null distributions of the $p$-values, first assuming that the sets of null and nonnull $p$-values are mutually independent or they are jointly positively dependent in the sense of being multivariate totally positive of order two (MTP$_2$) and then discarding that assumption about the overall dependence among the $p$-values.

description: The CMS experiment heavily relies on the CMSWEB cluster to host critical services for its operational needs. The cluster is deployed on virtual machines (VMs) from the CERN OpenStack cloud and is manually maintained by operators and developers. The release cycle is composed of several steps, from building RPMs, their deployment to perform validation, and integration tests. To enhance the sustainability of the CMSWEB cluster, CMS decided to migrate its cluster to a containerized solution such as Docker, orchestrated with Kubernetes (k8s). This allows us to significantly reduce the release upgrade cycle, follow the end-to-end deployment procedure, and reduce operational cost. This paper gives an overview of the current CMSWEB cluster and its issues. We describe the new architecture of the CMSWEB cluster in Kubernetes. We also provide a comparison of VM and Kubernetes deployment approaches and report on lessons learned during the migration process.
