description: Σκοπός της εργασίας ήταν η μελέτη της ψυχικής ανθεκτικότητας, των παραγόντων που την ενισχύουν αλλά και των παραγόντων κινδύνου, κατά την πανδημία COVID19 στον Κυπριακό πληθυσμό. Η μελέτη ήταν αναδρομική και η συλλογή δεδομένων έγινε μέσα από εθελοντική και ανώνυμη συμπλήρωση ηλεκτρονικών ερωτηματολογίων τον Μάιο 2022. Η έρευνα έλαβε έγκριση από την Επιτροπή Βιοηθικής Κύπρου. Η στατιστική ανάλυση, απλή και πολυπαραγοντική έγινε με το στατιστικό πρόγραμμα R. Στη μελέτη αναλύθηκαν τα δεδομένα από 244 συμμετέχοντες με έγκυρες απαντήσεις. Η μέση τιμή της κλίμακας ανθεκτικότητας κατά Connor and Davidson ήταν 68,95 με τυπική απόκλιση ±13,9. Στατιστικά σημαντικά χαμηλότερο σκορ ανθεκτικότητας στο τελικό πολυπαραγοντικό μοντέλο είχαν τα άτομα με κανένα ή ένα παιδί, όσοι δεν είχαν άριστη σωματική υγεία ή ένιωθαν νευρικότητα, εκνευρισμό, ανησυχία και μοναξιά. Άτομα με καλό οικογενειακό περιβάλλον, πολυμελείς οικογένειες, άτομα με καλή σωματική υγεία και όσοι δήλωσαν ότι ένιωθαν χαρούμενοι φάνηκε ότι μπορούσαν να προσαρμοστούν καλύτερα στις συνθήκες της πανδημίας COVID 19 αναπτύσσοντας ταυτόχρονα τους αντίστοιχους μηχανισμούς. Αντίθετα άτομα με έντονη ανησυχία, νευρικότητα και μοναξιά παρουσίασαν δυσκολίες διαχείρισης των ανωτέρω προκλήσεων. Η καλλιέργεια των αντίστοιχων ήπιων δεξιοτήτων, κατά πάσα πιθανότητα, μπορεί να καταστήσει τους ανθρώπους έτοιμους για αντιμετώπιση μελλοντικών δυσκολιών.
description: The aim of this research was to study mental resilience, the factors that strengthen it, and the risk factors, during the Covid 19 pandemic in the Cypriot population. The study was retrospective and the data was collected through voluntary and anonymous supplementation of electronic questionnaires during May 2022. The research received approval from the Cyprus Bioethics Committee. The statistical analysis, simple and multivariable, was done with the R Statistic Program. The study analysed the data from 244 participants with valid answers. The average value of the Connor and Davidson resilience scale was 68.95 with a standard deviation of ± 13.9. Statistically significant lower score of resilience according to the final multivariable model has; people with no or one child, who did not have excellent physical health or felt nervousness, irritation, anxiety, and loneliness. People with a good family environment, large families, people with good physical health, and those who said they felt happy seemed to be better adapted to the conditions of Covid 19 pandemic while developing their respective mechanisms. On the other hand, people with strong concern, nervousness, and loneliness have had difficulties managing the above challenges. The cultivation of their respective soft skills likely can make people ready to deal with future difficulties.

description: We discuss on noise in heterodyne holography in an off-axis configuration. We show that, for a weak signal, the noise is dominated by the shot noise on the reference beam. This noise corresponds to an equivalent noise on the signal beam of one photoelectron per pixel, for the whole sequence of images used to build the digital hologram.

description: The aim of this presentation is to illustrate the situation that prevailed at the end of the 19th century and the beginning of the 20th regarding preschool education in the Greek schools of the Ottoman Empire. The institution of kindergarten, adopted by the newly formed Greek state only at the end of the 19th century, will be mentioned. Also, the pedagogical principles, which prevailed at the time, will be listed, as well as the mode of operation of kindergartens. Of course, references to pre-school educations in the regions, which had not yet been annexed to the Greek taste, are also made. In general, the course of the institution of preschool education in unredeemed Hellen-ism follows the political and social developments and is instrumentalized with the ultimate goal of preserving the ethnic and religious identity of infants.

description: Axions differ from the other cold dark matter candidates in that they form a degenerate Bose gas. It is shown that their huge quantum degeneracy and large correlation length cause cold dark matter axions to thermalize through gravitational self-interactions when the photon temperature reaches approximately 500 eV. When they thermalize, the axions form a Bose-Einstein condensate. Their thermalization occurs in a regime, herein called the `condensed regime', where the Boltzmann equation is not valid because the energy dispersion of the particles is smaller than their interaction rate. We derive analytical expressions for the thermalization rate of particles in the condensed regime, and check the validity of these expressions by numerical simulation of a toy model. We revisit axion cosmology in light of axion Bose-Einstein condensation. It is shown that axions are indistinguishable from ordinary cold dark matter on all scales of observational interest, except when they thermalize or rethermalize. The rethermalization of axions that are about to fall in a galactic potential well causes them to acquire net overall rotation as they go to the lowest energy state consistent with the total angular momentum they acquired by tidal torquing. This phenomenon explains the occurrence of caustic rings of dark matter in galactic halos. We find that photons may reach thermal contact with axions and investigate the implications of this possibility for the measurements of cosmological parameters.

description: A diagonal Bianchi Type III space-time is treated, both at the classical and quantum level, in the context of Horava - Lifshitz gravity. The system of the classical equations of motion is reduced to one independent Abel's equation of the first kind. Closed form solution are presented for various values of the coupling constants appearing in the action. Due to the method used, solutions of Euclidean, Lorentzian and neutral signature are attained. The solutions corresponding to \lamda <> 1 are seen to develop curvature singularities as the other constants approach their Einsteinian values, in contrast to those with \lamda = 1 which tend to the known Einstein gravity solutions. At the quantum level, the resulting Wheeler-DeWitt equation is explicitly solved for \lamda = 1, σ= 0 and \lamda = 1/3 . The ensuing wave-functions diverge in the Einsteinian limit.

description: Neutrinos do oscillate, which up to our best knowledge implies that they are massive particles. As such, neutrinos should interact with gravitational fields. As their masses are tiny, the gravitational fields must be extremely strong. In this paper we study the influence of black holes described by non-trivial topologies on the neutrino oscillations. We present approximate analytical and numerical solutions of certain specific cases.

description: We present the first Herschel PACS and SPIRE results of the Vela C molecular complex in the far-infrared and submillimetre regimes at 70, 160, 250, 350, and 500 um, spanning the peak of emission of cold prestellar or protostellar cores. Column density and multi-resolution analysis (MRA) differentiates the Vela C complex into five distinct sub-regions. Each sub-region displays differences in their column density and temperature probability distribution functions (PDFs), in particular, the PDFs of the `Centre-Ridge' and `South-Nest' sub-regions appear in stark contrast to each other. The Centre-Ridge displays a bimodal temperature PDF representative of hot gas surrounding the HII region RCW 36 and the cold neighbouring filaments, whilst the South-Nest is dominated by cold filamentary structure. The column density PDF of the Centre-Ridge is flatter than the South-Nest, with a high column density tail, consistent with formation through large-scale flows, and regulation by self-gravity. At small to intermediate scales MRA indicates the Centre-Ridge to be twice as concentrated as the South-Nest, whilst on larger scales, a greater portion of the gas in the South-Nest is dominated by turbulence than in the Centre-Ridge. In Vela C, high-mass stars appear to be preferentially forming in ridges, i.e., dominant high column density filaments.

description: An inhomogeneous nonlinear Schrödinger equation is considered, that is invariant under $L^2$ scaling. The sharp condition for global existence of $H^1$ solutions is established, involving the $L^2$ norm of the ground state of the stationary equation. Strong instability of standing waves is proved by constructing self-similar solutions blowing up in finite time.

description: Chromospheric and prominence plasmas contain neutral atoms, which may change the plasma dynamics through collision with ions. Most of the atoms are neutral hydrogen, but a significant amount of neutral helium may also be present in the plasma with a particular temperature. Damping of MHD waves due to ion collision with neutral hydrogen is well studied, but the effects of neutral helium are largely unknown. We aim to study the effect of neutral helium in the damping of Alfven waves in solar partially ionized plasmas. We consider three-fluid magnetohydrodynamic (MHD) approximation, where one component is electron-proton-singly ionized helium and other two components are the neutral hydrogen and neutral helium atoms. We derive the dispersion relation of linear Alfven waves in isothermal and homogeneous plasma. Then we solve the dispersion relation and derive the damping rates of Alfven waves for different plasma parameters. The presence of neutral helium significantly enhances the damping of Alfven waves compared to the damping due to neutral hydrogen at certain values of plasma temperature (10000-40000 K) and ionization. Damping rates have a peak near the ion-neutral collision frequency, but decrease for the higher part of wave spectrum. Collision of ions with neutral helium atoms can be of importance for the damping of Alfven waves in chromospheric spicules and in prominence-corona transition regions.

description: Present experiments do not exclude that the neutron transforms into some invisible degenerate twin, so called mirror neutron, with an appreciable probability. These transitions are actively studied by monitoring neutron losses in ultra-cold neutron traps, where they can be revealed by their magnetic field dependence. In this work we reanalyze the experimental data acquired by the group of A.P. Serebrov at Institute Laue-Langevin, and find a dependence at more than 5σ away from the null hypothesis. This anomaly can be interpreted as oscillation to mirror neutrons with a timescale of few seconds, in the presence of a mirror magnetic field B'~0.1G at the Earth. If confirmed by future experiments, this will have a number of deepest consequences in particle physics and astrophysics.

SIDIS measurements at COMPASS provide better constraints on the strange and light sea quark helicity distributions. Single-longitudinal spin asymmetries in W-boson production have been observed at RHIC and will ultimately give new insights into the light quark and anti-quark helicity structure of the nucleon.

description: A control oriented, lumped parameter model for the tokamak transformer including the slow flux penetration in the plasma (skin effect transformer model) is presented. The model does not require detailed or explicit information about plasma profiles or geometry. Instead, this information is lumped in system variables, parameters and inputs. The model has an exact mathematical structure built from energy and flux conservation theorems, predicting the evolution and non linear interaction of the plasma current and internal inductance as functions of the primary coil currents, plasma resistance, non-inductive current drive and the loop voltage at a specific location inside the plasma (equilibrium loop voltage). Loop voltage profile in the plasma is substituted by a three-point discretization, and ordinary differential equations are used to predict the equilibrium loop voltage as function of the boundary and resistive loop voltages. This provides a model for equilibrium loop voltage evolution, which is reminiscent of the skin effect. The order and parameters of this differential equation are determined empirically using system identification techniques. Fast plasma current modulation experiments with Random Binary Signals (RBS) have been conducted in the TCV tokamak to generate the required data for the analysis. Plasma current was modulated in Ohmic conditions between 200kA and 300kA with 30ms rise time, several times faster than its time constant L/R\approx200ms. The model explains the most salient features of the plasma current transients without requiring detailed or explicit information about resistivity profiles. This proves that lumped parameter modeling approach can be used to predict the time evolution of bulk plasma properties such as plasma inductance or current with reasonable accuracy; at least in Ohmic conditions without external heating and current drive sources.

description: The role of mechanics is known to be of primary order in many arterial diseases; however, determining mechanical properties of arteries remains a challenge. This paper discusses the identifiability of the passive mechanical properties of a mouse carotid artery, taking into account the orientation of collagen fibres in the medial and adventitial layers. On the basis of 3D digital image correlation measurements of the surface strain during an inflation/extension test, an inverse identification method is set up. It involves a 3D finite element mechanical model of the mechanical test and an optimisation algorithm. A two-layer constitutive model derived from the Holzapfel model is used, with five and then seven parameters. The five-parameter model is successfully identified providing layer-specific fibre angles. The seven-parameter model is over parameterised, yet it is shown that additional data from a simple tension test make the identification of refined layer-specific data reliable.

description: The function E = F(v) expresses the dependence of a discrete eigenvalue E of the Schroedinger Hamiltonian H = -Δ+ vf(r) on the coupling parameter v. We use envelope theory to generate a functional sequence \{f^{[k]}(r)\} to reconstruct f(r) from F(v) starting from a seed potential f^{[0]}(r). In the power-law or log cases the inversion can be effected analytically and is complete in just two steps. In other cases convergence is observed numerically. To provide concrete illustrations of the inversion method it is first applied to the Hulthén potential, and it is then used to invert spectral data generated by singular potentials with shapes of the form f(r) = -a/r + b\sgn(q)r^q and f(r) = -a/r + b\ln(r), a, b > 0. For the class of attractive central potentials with shapes f(r) = g(r)/r, with g(0)< 0 and g'(r)\ge 0, we prove that the ground-state energy curve F(v) determines f(r) uniquely.

description: Affine gravity and the Palatini formalism contribute both to produce a simple and unique formula for calculating charges at spatial and null infinity for Lovelock type Lagrangians whose variational derivatives do not depend on second-order derivatives of the field components. The method is based on the covariant generalization due to Julia and Silva of the Regge-Teitelboim procedure that was used to define properly the mass in the classical formulation of Einstein's theory of gravity. Numerous applications reproduce standard results obtained by other secure but mostly specialized methods. As a novel application we calculate the Bondi energy loss in five dimensional gravity, based on the asymptotic solution given by Tanabe, Tanahashi and Shiromizu, and obtain, as expected, the same result. We also give the superpotential for Einstein-Gauss-Bonnet gravity and find the superpotential for Lovelock theories of gravity when the number of dimensions tends to infinity with maximally symmetrical boundaries. The paper is written in standard component formalism.

description: Through a systematic structural search we found an allotrope of carbon with Cmmm symmetry which we predict to be more stable than graphite for pressures above 10 GPa. This material, which we refer to as Z-carbon, is formed by pure sp3 bonds and is the only carbon allotrope which provides an excellent match to unexplained features in experimental X-ray diffraction and Raman spectra of graphite under pressure. The transition from graphite to Z-carbon can occur through simple sliding and buckling of graphene sheets. Our calculations predict that Z-carbon is a transparent wide band gap semiconductor with a hardness comparable to diamond.

description: Heterodyne Holography is a variant of Digital Holography, where the optical frequencies of signal and reference arms can be freely adjusted by acousto-optic modulators. Heterodyne Holography is an extremely versatile and reliable holographic technique, which is able the reach the shot noise limit in sensitivity at very low levels of signal. Frequency tuning enables Heterodyne Holography to become a Laser Doppler imaging technique that is able to analyze various kinds of motion.

description: Haag's theorem was extended to noncommutative quantum field theory in a general case when time does not commute with spatial variables. It was proven that if S-matrix is equal to unity in one of two theories related by unitary transformation, then the corresponding one in another theory is equal to unity as well. In fact this result is valid in any SO(1,1) invariant quantum field theory, of which an important example is noncommutative quantum field theory.

description: In this paper we prove the Fourier restriction theorem for $p=2$ on Riemannian symmetric spaces of noncompact type with real rank one which extends the earlier result proved in \cite[Theorem 1.1]{KRS}. This result depends on the weak $L^2$ estimates of the Poisson transform of $L^2$ function. By using this estimate of the Poisson transform we also characterizes all weak $L^2$ eigenfunction of the Laplace--Beltrami operator of Riemannian symmetric spaces of noncompact type with real rank one and eigenvalue $-(λ^2+ρ^2)$ for $λ\in\R\setminus\{0\}$.

description: A derivation of the spectral determinant of the Schrödinger operator on a metric graph is presented where the local matching conditions at the vertices are of the general form classified according to the scheme of Kostrykin and Schrader. To formulate the spectral determinant we first derive the spectral zeta function of the Schrödinger operator using an appropriate secular equation. The result obtained for the spectral determinant is along the lines of the recent conjecture.

description: Numerous formulations of finite volume schemes for the Euler and Navier-Stokes equations exist, but in the majority of cases they have been developed for structured and stationary meshes. In many applications, more flexible mesh geometries that can dynamically adjust to the problem at hand and move with the flow in a (quasi) Lagrangian fashion would, however, be highly desirable, as this can allow a significant reduction of advection errors and an accurate realization of curved and moving boundary conditions. Here we describe a novel formulation of viscous continuum hydrodynamics that solves the equations of motion on a Voronoi mesh created by a set of mesh-generating points. The points can move in an arbitrary manner, but the most natural motion is that given by the fluid velocity itself, such that the mesh dynamically adjusts to the flow. Owing to the mathematical properties of the Voronoi tessellation, pathological mesh-twisting effects are avoided. Our implementation considers the full Navier-Stokes equations and has been realized in the AREPO code both in 2D and 3D. We propose a new approach to compute accurate viscous fluxes for a dynamic Voronoi mesh, and use this to formulate a finite volume solver of the Navier-Stokes equations. Through a number of test problems, including circular Couette flow and flow past a cylindrical obstacle, we show that our new scheme combines good accuracy with geometric flexibility, and hence promises to be competitive with other highly refined Eulerian methods. This will in particular allow astrophysical applications of the AREPO code where physical viscosity is important, such as in the hot plasma in galaxy clusters, or for viscous accretion disk models.

Mid-infrared upconversion spectroscopy based on a Yb:fiber femtosecond laser

Publisher: name: arXiv

Subjects: subject: Optics (physics.optics)

description: We present a system for molecular spectroscopy using a broadband mid-infrared laser with near infrared detection. Difference frequency generation of a Yb:fiber femtosecond laser produced a mid-infrared (MIR) source tunable from 2100-3700 cm^-1 (2.7-4.7 microns) with average power up to 40 mW. The MIR spectrum was upconverted to near-infrared wavelengths for broadband detection using a two-dimensional dispersion imaging technique. Absorption measurements were performed over bandwidths of 240 cm^-1 (7.2 THz) with 0.048 cm^-1 (1.4 GHz) resolution, and absolute frequency scale uncertainty was better than 0.005 cm^-1 (150 MHz). The minimum detectable absorption coefficient per spectral element was determined to be 4.4 x 10^-7 cm^-1 from measurements in low pressure CH_4, leading to a detection limit of 2 parts-per-billion. The spectral range, resolution, and frequency accuracy of this system show promise for determination of trace concentrations in gas mixtures containing both narrow and broad overlapping spectral features, and we demonstrate this in measurements of air and solvent samples.

I know there's a problem with one of the OT constraints: Max(σ) is a faithfulness constraint but its formulation (on slide 38) looks like a markedness constraint. I'll fix it in later publication. The slides are exactly as they were for the seminar.

title: Use of NSCLC cell models to identify drug combinations active on LKB1-mutated NSCLCs
Creators: name: Colombo, Marika
Publisher: name: The Open University
Year: 2025

description: In the context of the lack of effective therapies for LKB1-mutated NSCLC, this thesis aimed to identify a valuable therapeutic strategy to manage these patients and improve their prognosis. Our previous research highlighted the sensitivity of LKB1-mutated NSCLC to the pharmacological inhibition of ERK. However, the presence of additional mutations that activate parallel ERK pathways abolished the effect of this drug, limiting its clinical use as monotherapy. This thesis project comprises three main parts. In the first section, using high throughput screening and drug repurposing strategies, the project identified ERK inhibitor (ERKi)-Entrectinib combination as a possible effective and specific therapeutic strategy for LKB1-mutated cell lines. The efficacy of this combination was confirmed, in the second section, both in vitro with different cell viability assay and in vivo where a significant slowdown of LKB1-mutated tumor growth was highlighted. Moreover, initial in vitro characterisation of the mechanism of action behind this combination activity showed that it induces deregulation of p-S6, a downstream mTOR protein, specifically in LKB1-mutated NSCLC cell lines. However, further studies are necessary to investigate the role of Entrectinib targets. Finally, the ERKi-Entrectinib combination treatment induced activation of apoptotic programmed cell death only in LKB1-mutated cell lines.
The third section of this work, instead, aimed at generating NSCLC 3D models, specifically Patient-Derived Xenograft (PDX)-derived Organoids (PDXO), which better mimic the 3D structure of the tumor mass and could bridge the gap between 2D cell lines and PDXs. Through the optimization and implementation of new method this thesis confirmed the technical feasibility, management and utility of PDXOs. This ex vivo model, indeed, fully recapitulate the characteristics of the NSCLC tumor of origin in terms of genetic fingerprinting, human lung epithelial cell composition, histological and mutational profile, and are suitable for pharmacological treatment test.
On effective sigma-boundedness and sigma-compactness

Subjects: subject: Logic (math.LO)

description: We prove several theorems on sigma-bounded and sigma-compact pointsets. We start with a known theorem by Kechris, saying that any lightface Σ^1_1 set of the Baire space either is effectively sigma-bounded (that is, covered by a countable union of compact lightface Δ^1_1 sets), or contains a superperfect subset (and then the set is not sigma-bounded, of course). We add different generalizations of this result, in particular, 1) such that the boundedness property involved includes covering by compact sets and equivalence classes of a given finite collection of lightface Δ^1_1 equivalence relations, 2) generalizations to lightface Σ^1_2 sets, 3) generalizations true in the Solovay model. As for effective sigma-compactness, we start with a theorem by Louveau, saying that any lightface Δ^1_1 set of the Baire space either is effectively sigma-compact (that is, is equal to a countable union of compact lightface Δ^1_1 sets), or it contains a relatively closed superperfect subset. Then we prove a generalization of this result to lightface Σ^1_1 sets.

Pictograms to improve antihypertensive medication adherence among patients with chronic kidney disease in a clinic setting
Creators: name: Guerrero, Analiza P.
Publisher: name: No Publisher Supplied
Year: 2022

description: Purpose of the Project. The purpose of the project was to implement pictograms to supplement textual and verbal instructions/information among patients with CKD to improve medication adherence in a clinic setting. Methodology. A quality improvement, practice change pilot study was conducted in a private Nephrology and Hypertension clinic. The validated Hill-Bone Scale, a medication adherence Likert type scale, was administered to assess self-reported antihypertensive medication adherence among sixty-four CKD patients. Thirteen patients were identified as non-adherent and were referred for a medication review. Pictograms were used to supplement textual and verbal medication instructions and information during medication review. The thirteen identified nonadherent patients completed the Hill-Bone Scale again at the conclusion of the study period. Related-Samples Wilcoxon Signed Rank Test was used to measure changes in adherence.Results. The results showed an improvement in antihypertensive medication adherence among CKD patients using the pictograms.Implications for Practice. Medication nonadherence is a global health concern among patients with chronic health conditions such as chronic kidney disease (CKD), a long-term complication of hypertension. Medication nonadherence is associated with increased mortality and morbidity, and high healthcare costs. Literature suggests that the best approach to increasing medication adherence is combining evidence-based strategies and emerging practices that use an approach that is patient-centered with emphasis on the patient's ability to understand medication information and to follow instructions not only through textual and verbal but also visual cues.

description: The statistical inverse problem of estimating the probability distribution of an infinite-dimensional unknown given its noisy indirect observation is studied in the Bayesian framework. In practice, one often considers only finite-dimensional unknowns and investigates numerically their probabilities. As many unknowns are function-valued, it is of interest to know whether the estimated probabilities converge when the finite-dimensional approximations of the unknown are refined. In this work, the generalized Bayes formula is shown to be a powerful tool in the convergence studies. With the help of the generalized Bayes formula, the question of convergence of the posterior distributions is returned to the convergence of the finite-dimensional (or any other) approximations of the unknown. The approach allows many prior distributions while the restrictions are mainly for the noise model and the direct theory. Three modes of convergence of posterior distributions are considered -- weak convergence, setwise convergence and convergence in variation. The convergence of conditional mean estimates is studied. Several examples of applicable infinite-dimensional non-Gaussian noise models are provided, including a generalization of the Cameron-Martin formula for certain non-Gaussian measures. Also, the well-posedness of Bayesian statistical inverse problems is studied.
