description: The interaction of Galactic-Centre (GC) super bubbles (GSB) with the gaseous disc and halo of the Milky Way is investigated using radio continuum, X-ray, HI and CO line surveys. The radio North Polar Spur (NPS) constitutes the brightest eastern ridge of GSB, brightening towards the galactic plane and reaching $ l = 22°, \ b = + 2°$ at the sharpest end, where it intersects the tangential direction of the 3-kpc expanding ring and crater. Examination of the spur ridges reveals that the entire GSB, including the NPS and its counter spurs, constitutes a GC-symmetrical $Ω/$\rotatebox[origin=c]{180}{$Ω$} shape. The thickness and gas density of the HI and CO discs are shown to increase sharply from the inside (lower longitude) to the outside of the 3-kpc crater. Formation of crater is explained by the sweeping of the upper layer of disc gas by the shock wave from the GC by the explosion $ \sim 10 $ My ago with the emitted energy of several $10 ^ {55} $ ergs. Based on the discussion, a unified view on the structure and formation mechanism of GSB is presented.

description: We study the structure and evolution of neutron stars (NS) the interiors of which are modeled using microscopic approaches and constrained by the condition that the equation of state (EoS) of matter extrapolated to high densities should not contradict known observational data from compact stars and experimental data from heavy-ion collisions (HIC). We use modern cooling simulations to extract distributions of NS masses required to reproduce those of the yet sparse data in the Temperature-Age (TA) plane. By comparing the results with a mass distribution for young, nearby NSs used in population synthesis we can sharpen the NS cooling constraints.

description: Single-turn coil (STC) technique is a convenient way to generate ultrahigh magnetic fields of more than 100 T. During the field generation, the STC explosively destructs outward due to the Maxwell stress and Joule heating. Unfortunately, the STC does not work at its full potential because it has already expanded when the maximum magnetic field is reached. Here, we propose an easy way to delay the expansion and increase the maximum field by using a mass-loaded STC. By loading clay on the STC, the field profile drastically changes, and the maximum field increases by 4 %. This method offers an access to higher magnetic fields for physical property measurements.

The Most Severe Test for Hydrophobicity Scales: Two Proteins with 88% Sequence Identity but Different Structure and Function

description: Protein-protein interactions (protein functionalities) are mediated by water, which compacts individual proteins and promotes close and temporarily stable large-area protein-protein interfaces. In their classic paper Kyte and Doolittle (KD) concluded that the "simplicity and graphic nature of hydrophobicity scales make them very useful tools for the evaluation of protein structures". In practice, however, attempts to develop hydrophobicity scales (for example, compatible with classical force fields (CFF) in calculating the energetics of protein folding) have encountered many difficulties. Here we suggest an entirely different approach, based on the idea that proteins are self-organized networks, subject to finite-scale criticality (like some network glasses). We test this proposal against two small proteins that are delicately balanced between alpha and alpha/beta structures, with different functions encoded with only 12% of their amino acids. This example explains why protein structure prediction is so challenging, and it provides a severe test for the accuracy and content of hydrophobicity scales. The new method confirms KD's evaluation, and at the same time suggests that protein structure, dynamics and function can be best discussed without using CFF.

description: From Swift monitoring of a sample of active galactic nuclei (AGN) we found a transient X-ray obscuration event in Seyfert-1 galaxy NGC 3227, and thus triggered our joint XMM-Newton, NuSTAR, and Hubble Space Telescope (HST) observations to study this event. Here in the first paper of our series we present the broadband continuum modelling of the spectral energy distribution (SED) for NGC 3227, extending from near infrared (NIR) to hard X-rays. We use our new spectra taken with XMM-Newton, NuSTAR, and HST/COS in 2019, together with archival unobscured XMM-Newton, NuSTAR, and HST/STIS data, in order to disentangle various spectral components of NGC 3227 and recover the underlying continuum. We find the observed NIR-optical-UV continuum is explained well by an accretion disk blackbody component (Tmax = 10 eV), which is internally reddened by E(B-V) = 0.45 with a Small Magellanic Cloud (SMC) extinction law. We derive the inner radius (12 Rg) and the accretion rate (0.1 solar mass per year) of the disk by modelling the thermal disk emission. The internal reddening in NGC 3227 is most likely associated with outflows from the dusty AGN torus. In addition, an unreddened continuum component is also evident, which likely arises from scattered radiation, associated with the extended narrow-line region (NLR) of NGC 3227. The extreme ultraviolet (EUV) continuum, and the 'soft X-ray excess', can be explained with a 'warm Comptonisation' component. The hard X-rays are consistent with a power-law and a neutral reflection component. The intrinsic bolometric luminosity of the AGN in NGC 3227 is about 2.2e+43 erg/s in 2019, corresponding to 3% Eddington luminosity. Our continuum modelling of the new triggered data of NGC 3227 requires the presence of a new obscuring gas with column density NH = 5e+22 cm^-2, partially covering the X-ray source (Cf = 0.6).

description: Min-max saddle point games have recently been intensely studied, due to their wide range of applications, including training Generative Adversarial Networks (GANs). However, most of the recent efforts for solving them are limited to special regimes such as convex-concave games. Further, it is customarily assumed that the underlying optimization problem is solved either by a single machine or in the case of multiple machines connected in centralized fashion, wherein each one communicates with a central node. The latter approach becomes challenging, when the underlying communications network has low bandwidth. In addition, privacy considerations may dictate that certain nodes can communicate with a subset of other nodes. Hence, it is of interest to develop methods that solve min-max games in a decentralized manner. To that end, we develop a decentralized adaptive momentum (ADAM)-type algorithm for solving min-max optimization problem under the condition that the objective function satisfies a Minty Variational Inequality condition, which is a generalization to convex-concave case. The proposed method overcomes shortcomings of recent non-adaptive gradient-based decentralized algorithms for min-max optimization problems that do not perform well in practice and require careful tuning. In this paper, we obtain non-asymptotic rates of convergence of the proposed algorithm (coined DADAM$^3$) for finding a (stochastic) first-order Nash equilibrium point and subsequently evaluate its performance on training GANs. The extensive empirical evaluation shows that DADAM$^3$ outperforms recently developed methods, including decentralized optimistic stochastic gradient for solving such min-max problems.

description: Using Kalman techniques, it is possible to perform optimal estimation in linear Gaussian state-space models. We address here the case where the noise probability density functions are of unknown functional form. A flexible Bayesian nonparametric noise model based on Dirichlet process mixtures is introduced. Efficient Markov chain Monte Carlo and Sequential Monte Carlo methods are then developed to perform optimal batch and sequential estimation in such contexts. The algorithms are applied to blind deconvolution and change point detection. Experimental results on synthetic and real data demonstrate the efficiency of this approach in various contexts.

Στην φιλοσοφία του Hegel, η ουσία αποκαλύπτεται ως η αρνητικότητα που εκφέρει την αλήθεια του Είναι, στο πλαίσιο μιας αυστηρής διαλεκτικής που ωθείται από την αρνητική εαυτοσυσχέτιση των υπό συγκρότηση εννοιών• οι αρχικές έννοιες της Λογικής αυτής, οι εναρκτήριες κατηγορίες της Λογικής της ουσίας, αποτελούν το θέμα της εργασίας αυτής. Στο πλαίσιο αυτό, επιχειρείται η ανασυγκρότηση του εγελιανού κειμένου και υπό την προοπτική που προτείνεται, επιχειρείται η διαύγαση του πρώτου Τμήματος της «διδασκαλίας περί της ουσίας» που αρχίζει από το κεφάλαιο: η «φαινομενικότητα» και ολοκληρώνεται στο κεφάλαιο: ο «εξ υπαρχής λόγος».
description: This thesis examines the first of the three Sections of the “doctrine of essence”, which is the second book of G.F.W. Hegel’s Science of Logic. In Hegel’s philosophy, essence is revealed as the negativity that delivers the truth of Being, in the context of a rigorous dialectic that is generated by the negative self-reference of the concepts under construction; the first concepts of this Logic, the starting categories of the Logic of essence, constitute the subject of this thesis. In this context, it is attempted to reconstruct the hegelian text and under the perspective proposed, it is attempted to elucidate the first Section of the “doctrine of essence” which starts from the chapter: “shine” and is completed to the chapter: “ground”.

description: The development of covalent inhibitors against KRAS G12C represents a major milestone in treatment of RAS-driven cancers, especially in non-small cell lung cancer (NSCLC), where KRAS G12C is one of the most common oncogenic driver. Here we investigated if additional KRAS mutations co-occur with KRAS G12C (c.34G>T) in NSCLC tumours and if such mutation co-occurrence affects cellular response to G12C-specific inhibitors. Analysis of a large cohort of NSCLC patients whose tumours harboured KRAS mutations revealed co-occurring KRAS mutations in up to 8% of tumours with the KRAS c.34G>T mutation. KRAS c.35G>T was the most frequently co-occurring mutation, and could occur on the same allele (in cis) translating to a single mutant KRAS G12F protein, or on the other allele (in trans), translating to separate G12C and G12V mutant proteins. Introducing KRAS c.35G>T in trans in the KRAS G12C lung cancer model NCI-H358, as well as the co-occurrence in cis in the KRAS G12F lung cancer model NCI-H2291 led to cellular resistance to the G12C-specific inhibitor AZ'8037 due to continuing active MAPK and PI3K cascades in the presence of the inhibitor. Overall, our study provides a comprehensive assessment of co-occurring KRAS mutations in NSCLC and in vitro evidence of the negative impact of co-occurring KRAS mutations on cellular response to G12C inhibitors, highlighting the need for a comprehensive KRAS tumour genotyping for optimal patient selection for treatment with a KRAS G12C inhibitor.

description: We describe the goals, design, implementation, and initial progress of the UKIRT Infrared Deep Sky Survey (UKIDSS), a seven year sky survey which began in May 2005, using the UKIRT Wide Field Camera. It is a portfolio of five survey components covering various combinations of the filter set ZYJHK and H_2. The Large Area Survey, the Galactic Clusters Survey, and the Galactic Plane Survey cover approximately 7000 square degrees to a depth of K~18; the Deep Extragalactic Survey covers 35 square degrees to K~21, and the Ultra Deep Survey covers 0.77 square degrees to K~23. Summed together UKIDSS is 12 times larger in effective volume than the 2MASS survey. The prime aim of UKIDSS is to provide a long term astronomical legacy database; the design is however driven by a series of specific goals -- for example to find the nearest and faintest sub-stellar objects; to discover Population II brown dwarfs, if they exist; to determine the substellar mass function; to break the z=7 quasar barrier; to determine the epoch of re-ionisation; to measure the growth of structure from z=3 to the present day; to determine the epoch of spheroid formation; and to map the Milky Way through the dust, to several kpc. The survey data are being uniformly processed, and released in stages through the WFCAM Science Archive (WSA : http://surveys.roe.ac.uk/wsa). Before the formal survey began, UKIRT and the UKIDSS consortium collaborated in obtaining and analysing a series of small science verification (SV) projects to complete the commissioning of the camera. We show some results from these SV projects in order to demonstrate the likely power of the eventual complete survey. Finally, using the data from the First Data Release we assess how well UKIDSS is meeting its design targets so far.

description: We report the detection with the Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA) of 530 Hz burst oscillations in a thermonuclear (type I) burst from the transient X-ray source A1744-361. This is only the second burst ever observed from this source, and the first to be seen in any detail. Our results confirm that A1744-361 is a low mass X-ray binary (LMXB) system harboring a rapidly rotating neutron star. The oscillations are first detected along the rising edge of the burst, and they show evidence for frequency evolution of a magnitude similar to that seen in other burst sources. The modulation amplitude and its increase with photon energy are also typical of burst oscillations. The lack of any strong indication of photospheric radius expansion during the burst suggests a 9 kpc upper limit of the source distance. We also find energy dependent dips, establishing A1744-361 as a high inclination, dipping LMXB. The timescale between the two episodes of observed dips suggests an orbital period of ~ 97 minutes. We have also detected a 2 - 4 Hz quasi-periodic-oscillation (QPO) for the first time from this source. This QPO appears consistent with ~ 1 Hz QPOs seen from other high-inclination systems. We searched for kilohertz QPOs, and found a suggestive 2.3 sigma feature at 800 Hz in one observation. The frequency, strength, and quality factor are consistent with that of a lower frequency kilohertz QPO, but the relatively low significance argues for caution, so we consider this a tentative detection requiring confirmation.

description: Violations of Lorentz invariance that appear via operators of dimension four or less are completely parameterized in the Standard Model Extension (SME). In the pure photonic sector of the SME, there are nineteen dimensionless, Lorentz-violating parameters. Eighteen of these have experimental upper bounds ranging between 10^{-11} and 10^{-32}; the remaining parameter, k_tr, is isotropic and has a much weaker bound of order 10^{-4}. In this Brief Report, we point out that k_tr gives a significant contribution to the anomalous magnetic moment of the electron and find a new upper bound of order 10^{-8}. With reasonable assumptions, we further show that this bound may be improved to 10^{-14} by considering the renormalization of other Lorentz-violating parameters that are more tightly constrained. Using similar renormalization arguments, we also estimate bounds on Lorentz violating parameters in the pure gluonic sector of QCD.

description: Control firmware in unmanned aerial vehicles (UAVs) uses sensors to model and manage flight operations, from takeoff to landing to flying between waypoints. However, sensors can fail at any time during a flight. If control firmware mishandles sensor failures, UAVs can crash, fly away, or suffer other unsafe conditions. In-situ model checking finds sensor failures that could lead to unsafe conditions by systematically failing sensors. However, the type of sensor failure and its timing within a flight affect its manifestation, creating a large search space. We propose Avis, an in-situ model checker to quickly uncover UAV sensor failures that lead to unsafe conditions. Widely used control firmware already support operating modes. Avis injects sensor failures as the control firmware transitions between modes - a key execution point where mishandled software exceptions can trigger unsafe conditions. We implemented Avis and applied it to ArduPilot and PX4. Avis found unsafe conditions 2.4X faster than Bayesian Fault Injection, the leading, state-of-the-art approach. Within the current code base of ArduPilot and PX4, Avis discovered 10 previously unknown software bugs that lead to unsafe conditions. Additionally, we reinserted 5 known bugs that caused serious, unsafe conditions and Avis correctly reported all of them.

Με σκοπό την υποβοήθηση ανάλογων μελετών, αναπτύσσουμε μία βιβλιοθήκη σε C++ και παρέχουμε λειτουργίες κοσμολογικού ενδιαφέροντος (π.χ. υπολογιστής κοσμικών αποστάσεων). Επίσης αναπτύσσουμε ένα multiplatform γραφικό περιβάλλον που διαχειρίζεται αρχεία, υπολογίζει και απεικονίζει MSTs, εμφανίζει στατιστικές και κατανομές, κτλ. Παρουσιάζουμε τα αποτελέσματα υπολογιστικών πειραμάτων επιβεβαίωσης καλής λειτουργίας και υπολογιστικής πολυπλοκότητας ενώ εφαρμόζουμε το λογισμικό στις κοσμολογικές προσομοιώσεις DEUSS με σκοπό τη σύγκριση δύο κοσμολογικών μοντέλων.
description: During the last 20 years, redshift surveys and cosmological N-body simulations with the aid of powerful supercomputers, changed our view of the large-scale structure of universe. Sensitive and fast methods are crucial in the analysis and comparison of artificial or observational data. The widely used 2-point correlation function often fails to distinguish data from cosmological models of different initial conditions, whereas the more sensitive correlation functions of higher order (n-point correlation functions) are computationally intensive. The graph theoretic Minimum Spanning Tree technique addresses these problems as a MST depends on correlation functions of all orders. We study MST algorithms and possible optimizations specific for applications on 3D space. In order to aid similar studies, we develop a C++ library with cosmological add-ons (e.g. cosmic distance calculator.) Additionally, we develop a multi-platform graphical user interface for manipulating files, finding and plotting MSTs, displaying statistical reports, etc. We present the results of numerical experiments that verify the correct function and time complexity of the library's algorithms and apply the software on DEUSS cosmological simulations in order to compare two cosmological models.

description: We prove that vector fields described by the generalized Proca class of theories do not admit a consistent coupling to a gravitational sector defined by a scalar-tensor theory of the degenerate type. Under the assumption that there exists a frame in which the Proca field interacts with gravity only through the metric tensor, our analysis shows that at least one of the constraints associated with the degeneracy of the scalar-tensor sector is inevitably lost whenever the vector theory includes a coupling to the Christoffel connection.

description: The experimental line shape broadening observed in adsorbate diffusion on metal surfaces with increasing coverage is usually related to the nature of the adsorbate-adsorbate interaction. Here we show that this broadening can also be understood in terms of a fully stochastic model just considering two noise sources: (i) a Gaussian white noise accounting for the surface friction, and (ii) a shot noise replacing the physical adsorbate-adsorbate interaction potential. Furthermore, contrary to what could be expected, for relatively weak adsorbate-substrate interactions the opposite effect is predicted: line shapes get narrower with increasing coverage.

Τα καθαριστικά που χρησιμοποιήθηκαν είναι το κιτρικό τριαμμώνιο (triammonium citrate, TAC) και το αιθυλενοδιάμινοτετραοξικό οξύ (ethylenediaminetetraacetic acid, EDTA) σε συγκεντρώσεις 0,5%, 1% και 2% σε νερό και ο μη πολικός διαλύτης είναι ο stoddart. Μακροσκοπικά αλλά και μικροσκοπικά έγινε μελέτη της επιφάνειας των φίλμ πριν και μετά τον καθαρισμό τόσο των επικαλυμμένων με ρύπους αλλά και των καθαρών. Με τη χρήση ηλεκτρονικού μικροσκοπίου σάρωσης (SEM) μελετήθηκε η μορφολογία όλων των φίλμ πριν και μετά την τεχνητή εναπόθεση ρύπων. Επίσης έγινε χαρακτηρισμός του χρώματος των ακρυλικών φίλμ με τη βοήθεια χρωματομέτρου και προσδιορίστηκαν η παράμετρος λαμπρότητα, L*, ο χρωματικός ερεθισμός στον άξονα κόκκινου-πράσινου, a*, και ο χρωματικός ερεθισμός στον άξονα κίτρινου-μπλε, b*. Επίσης μέσω της φασματοσκοπίας Raman πραγματοποιήθηκε ποιοτικός χαρακτηρισμός των χρωστικών. Τέλος λαμβάνοντας υπόψιν τα αποτελέσματα των χαρακτηρισμών διαπιστώθηκε ότι τα χηλικά καθαριστικά TAC και EDTA είναι ιδιαίτερα αποτελεσματικά όσον αφορά τον καθαρισμό από τους ρύπους αλλά και την αλληλεπίδρασή τους με την επιφάνεια του ακρυλικού φίλμ.
description: Τhe behaviour of acrylic films containing organic pigments, Pigment yellow 3 (PY3) and Pigment red 264 (PR264), and inorganic, Pigment yellow 42 (PY42) and Pigment red 101 (PR101), was studied towards two chelating cleaning agents, water and a non polar solvent, stoddart, during their surface cleaning from soil deposited on them. Triammonium citrate (TAC) and ethylenediaminetetraacetic acid (EDTA) were used as cleaning agents at concentrations of 0,5%, 1% and 2% in water. The surface of the films was studied macroscopically and microscopically before and after the effect of cleaning agents on both coated with soil films and the clean one. Moreover the morphology of thermally aged films was studied by scanning electron microscopy (SEM). Characterization of the color of acrylic films was carried out by colorimetry through the determination of parameters brightness, L *, red-green axis stimulation, a *, and yellow-blue axis stimulation, b *. The chemical composition of the films was examined by Raman spectroscopy. The results of characterization methods demonstrated that the most appropriate cleaning agent for the cleaning of the soil on films were TAC and EDTA taking into account its interaction with the surface of the acrylic film. .

description: Noise profile of Voltage Dependent Anion Channel (VDAC) is investigated in open channel state. Single-channel currents through VDAC from mitochondria of rat brain reconstituted into a planar lipid bilayer are recorded under different voltage clamped conditions across the membrane. Power spectrum analysis of current indicates powerlaw noise of 1/f nature. Moreover, this 1/f nature of the open channel noise is seen throughout the range of applied membrane potential -30 to +30 mV. It is being proposed that 1/f noise in open ion channel arises out of obstruction in the passage of ions across the membrane. The process is recognised as a phenomenon of self-organized-criticality (SOC) like sandpile avalanche and other physical systems. Based on SOC it has been theoretically established that the system of ion channel follows powerlaw noise as observed in our experiments. We also show that the first-time return probability of current fluctuations obeys a powerlaw distribution.

Science and technology education in a civilizing mission
Creators: name: MacIvor, Madeleine
Publisher: name: University of British Columbia
Year: 2008

description: This thesis is a study of science and technology education in the context of an early Aboriginal-missionary interaction at Fort Simpson and Metlakatla, British Columbia between 1857 and 1887. Drawing on a variety of historical sources, the study investigates how science and technology education were used by lay missionary William Duncan to further the dual goals of Christianization and civilization among the Tsimshian. The thesis also investigates the varying responses of the Tsimshian to Duncan’s educational initiatives. The thesis argues that science and technology education at Fort Simpson and Metlakatla was implemented in an attempt to culturally dominate the People. Duncan used science and technology education to promote Christianity, to undermine the People's traditional beliefs about the natural world, to promote literacy over orality, and to inculcate Victorian work values. Furthermore, the technological and domestic training introduced by Duncan facilitated the development of materials and skills necessary for the physical development of the mission village, isolated the People from other labour markets, and encouraged industriousness. Domestic education was intended to give the women the skills necessary to adopt European dress and to prepare them for their roles as mothers in Christian, civilized homes. Science and technology education was also intended to fill the void resulting from the banning of traditional practices. The People, however, were not passive victims of Duncan's educational practices. While many rejected Western schooling, others accommodated schooling for various intellectual, practical, economic, political, cultural, and spiritual reasons. Resistance was always a theme in the history of schooling in Fort Simpson and Metlakatla. Resistance was particularly strong among the Chiefs, and this resistance was a factor in the relocation of the People from Fort Simpson to Metlakatla, B.C., and later to Metlakatla, Alaska. This case study illustrates that Western school science was a site of cultural domination and resistance, and raises questions about appropriate education for Aboriginal people in science and technology. The thesis concludes by locating this case study within the history of Western schooling of Aboriginal people, and calls for the reconstruction of the science curriculum to meet the needs and aspirations of the People.

description: Η Αναπτυξιακή Διαταραχή του Κινητικού Συντονισμού (ΑΔΚΣ) είναι μια διαταραχή της κινητικής ανάπτυξης που επηρεάζει περίπου το 10 % των παιδιών σχολικής ηλικίας διεθνώς. Οι γραφοκινητικές δεξιότητες θεωρούνται τμήμα της γενικότερης οπτικοαντιληπτικής ικανότητας των παιδιών αυτής της ηλικίας. Σκοπός της παρούσας έρευνας ήταν ο εντοπισμός του ποσοστού παιδιών με άτυπη ΑΔΚΣ στα υπό μελέτη σχολεία και, στη συνέχεια, η σύγκριση των ποιοτικών γραφοκινητικών χαρακτηριστικών των παιδιών με και χωρίς άτυπη ΑΔΚΣ. 131 μαθητές συμμετείχαν στις μετρήσεις, από τους οποίους το 14 % (18 μαθητές) παρουσίασε σοβαρή ΑΔΚΣ. Επιπλέον, άλλα 18 παιδιά βρέθηκε να βρίσκονται σε κίνδυνο εμφάνισης ΑΔΚΣ. 12 μαθητές με άτυπη ΑΔΚΣ και 13 χωρίς εκτέλεσαν ακολούθως τη Δοκιμασία Αξιολόγησης Γραφοκινητικών Δεξιοτήτων 4-6 (ΚΑΓΔ 4-6) από την οποία επιλέχθηκαν τα ποιοτικά χαρακτηριστικά. Στατιστικά σημαντική διαφορά μεταξύ των δύο ομάδων βρέθηκε μόνο στην εξαρτημένη μεταβλητή του επιδέξιου χειρισμού ψαλιδιού (p< .05), αν και οι επιδόσεις των παιδιών με άτυπη ΑΔΚΣ ήταν χαμηλότερες σε όλες ανεξαιρέτως τις μεταβλητές που συνδέθηκαν με τα ποιοτικά χαρακτηριστικά της γραφής. Συνεπώς, φάνηκε να υπάρχει σύνδεση μεταξύ της ύπαρξης άτυπης ΑΔΚΣ και γραφοκινητικών δυσκολιών ως προς την ποιότητα γραφής, αν και χρειάζονται επιπλέον μελέτες πάνω στο θέμα. Τα ευρήματα κρίνεται πως μπορούν να βοηθήσουν στο σχεδιασμό πιθανών προγραμμάτων υποστήριξης των παιδιών με ΑΔΚΣ ως προς τις γραφοκινητικές δυσκολίες που φαίνεται να αντιμετωπίζουν.
description: Developmental coordination disorder (DCD) is a motor development disorder which affects roughly 10% of school-aged children worldwide. Handwriting skills are considered part of the general visual-perceptual motor ability in children of this age. The purpose of this study was to identify the incidence of atypical DCD in schools under study and then compare the handwriting characteristics in children with and without atypical DCD. 131 students participated in the study, 14% (18 students) was found to have severe DCD. An additional 18 students demonstrated signs of borderline DCD. 12 students with atypical DCD and 13 without subsequently completed the Criterion of Graphomotor Skills Assessment 4-6 (KAGD 4-6). Statistically significant differences between the two groups were found only on the dependent variable of skilled scissors handling (p

description: In this methodological paper, we first review the classic cubic Diophantine equation $a^3 + b^3 + c^3 = d^3$, and consider the specific class of solutions $q_1^3 + q_2^3 + q_3^3 = q_4^3$ with each $q_i$ being a binary quadratic form. Next we turn our attention to the familiar sums of powers of the first $n$ positive integers, $S_k = 1^k + 2^k + \cdots + n^k$, and express the squares $S_k^2$, $S_m^2$, and the product $S_k S_m$ as a linear combination of power sums. These expressions, along with the above quadratic-form solution for the cubic equation, allows one to generate an infinite number of relations of the form $Q_1^3 + Q_2^3 + Q_3^3 = Q_4^3$, with each $Q_i$ being a linear combination of power sums. Also, we briefly consider the quadratic Diophantine equations $a^2 + b^2 + c^2 = d^2$ and $a^2 + b^2 = c^2$, and give a family of corresponding solutions $Q_1^2 + Q_2^2 + Q_3^2 = Q_4^2$ and $Q_1^2 + Q_2^2 = Q_3^2$ in terms of sums of powers of integers.
