(E)race : symbolic ethnicity and the Asian image
Creators: name: Lee, Stephen
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines why and how dominant Asian images continue to permeate cinema through the reinforcement of Asian symbols and icons. Chapter one develops a system model to explain the communicative and social properties of Asian representation. Chapters two and three show how dominant cinema and Asian-North American alternative cinema follow the same communicative and social models which, in turn, lead to stereotypical Asian images. Using the communication theories of Andrew Tudor, the sociological theories of Herbert Gans and the theories of Orientalism of Edward Said, the thesis shows how historical Asian icons, continually used in cinema, are symptoms of a society that is moving closer to a homogenous culture. In effect, the Asian identity is becoming deculturalized. The argument is made that by examining the issue of Asian identity through cinematic and social theory, Asian North American cultural producers can develop a critical self-evaluation beyond what exists at present.

description: We show that the use of the fourth-root trick in lattice QCD with staggered fermions corresponds to a non-local theory at non-zero lattice spacing, but argue that the non-local behavior is likely to go away in the continuum limit. We give examples of this non-local behavior in the free theory, and for the case of a fixed topologically non-trivial background gauge field. In both special cases, the non-local behavior indeed disappears in the continuum limit. Our results invalidate a recent claim that at non-zero lattice spacing an additive mass renormalization is needed because of taste-symmetry breaking.

description: Η παρούσα εισήγηση επιχειρεί μία διείσδυση στις νέες διατάξεις της εκκρεμοδικίας του Κανονισμού 1215/2012. Εξετάζει την ιστορική εξέλιξη του θεσμού της εκκρεμοδικίας από τη Σύμβαση των Βρυξελλών έως τον Κανονισμό 44/2001 (Βρυξέλλες Ι), εστιάζοντας στα προβλήματα που ανέκυψαν κατά την εφαρμογή του και οδήγησαν στην τροποποίησή του από τον Κανονισμό 1215/2012. Ειδική έμφαση αποδίδεται στο φαινόμενο της τορπίλης, το οποίο αναδείχθηκε μέσα από την πρακτική των εν δυνάμει οφειλετών – κυρίως σε υποθέσεις διπλωμάτων ευρεσιτεχνίας – να ασκούν προληπτικά αναγνωριστική αγωγή περί μη ύπαρξης παραβάσεως στο πρόσωπό τους ενώπιον ενός δικαστηρίου κράτους – μέλους, αρμόδιου ή μη, συνήθως γνωστού για βραδυκινησία στην απονομή της δικαιοσύνης. Στο πλαίσιο αυτό εξετάζονται οι τροποποιήσεις που επέφερε ο Κανονισμός, η σπουδαιότερη εκ των οποίων ήταν η ανατροπή της αρχής της χρονικής προτεραιότητας του πρώτου επιληφθέντος δικαστηρίου σε περίπτωση υπάρξεως ρήτρας παρέκτασης υπέρ ενός μεταγενεστέρως επιληφθέντος δικαστηρίου. Επιχειρείται και μία συγκριτική επισκόπηση των ρυθμίσεων της εκκρεμοδικίας στο ελληνικό, στο ηπειρωτικό και στο αγγλοσαξωνικό δίκαιο τόσο μεταξύ τους όσο και με τον Κανονισμό 1215/2012. Ειδική αναφορά γίνεται στη σύγκριση των ρυθμίσεων του ελληνικού δικαίου περί εκκρεμοδικίας με τις αντίστοιχες του Κανονισμού 1215/2012. Τέλος, γίνεται μία αποτίμηση της συμβολής των νέων διατάξεων στον περιορισμό του φαινομένου της τορπίλης.
description: The present paper attempts a penetration into the new provisions of lis pendens of the Regulation 1215/2012. It examines the historical development of the institution of lis pendens from the Brussels Convention to the Regulation 44/2001 (Brussels I), focusing on the problems encountered during its implementation, which led to its amendment by the Regulation 1215/2012. Special emphasis is placed on the torpedo actions, which emerged mainly in patent matters through the practice of potential infringers to bring a preventive declaratory action for the non- existence of an infringement in their face before a court of a member – state, competent or not, usually known for slowness in the administration of justice. In this context, we examine the amendments made by the Regulation, the most important of which was the overthrow of the principle of time priority of the court first seised in case of existence of a prorogation clause for the court seised subsequently. A comparative overview of the lis pendens rules in Greek, in continental and anglo-saxon law both among themselves and with the Regulation 1215/2012 is attempted. Specific reference is made to the comparison of Greek law rules on lis pendens with those of Regulation 1215/2012. Finally, we make an assessment of the contribution of the new provisions to the limitation of torpedo actions.
Properties of the Reissner-Nordström Spacetimes with a Nonzero Cosmological Constant

description: Properties of the Reissner-Nordström black-hole and naked-singularity spacetimes with a nonzero cosmological constant are represented by their geodetical structure and embedding diagrams of the central planes of both the ordinary geometry and associated optical reference geometry. Motion of test particles and photons is described in terms of an appropriate `effective potential.' Circular geodesics are discussed and photon escape cones are determined. In all asymptotically anti-dS black-hole spacetimes and some asymptotically dS black-hole spacetimes a region containing stable circular geodesics exists, which allows accretion processes in the disk regime. The inner region is limited from below by particles with zero angular momentum that are located in stable equilibrium positions. The inertial and gravitational forces related to the optical reference geometry are introduced and specified for the circular motion. It is shown how the properties of the centrifugal force are closely related to the properties of the optical reference geometry embedding diagrams.

The putative role of the ventral septal area of the brain in the integration of cardiovascular regulation during endotoxin induced fever
Creators: name: McCashin, Marianne Roberta Hamilton Marshall
Publisher: name: University of British Columbia
Year: 2009

description: During fever, cardiovascular changes have been seen to accompany the change in body temperature. There is evidence to implicate an area of the brain called the ventral septal area/ diagonal band of Broca (VSA/DBB) in both thermoregulation and cardiovascular control. This thesis investigates the possibility that neurons of the VSA/DBB which are known to be involved in thermoregulation during fever, may also be involved in some aspect of cardiovascular control during fever induced by endotoxin. The investigation was performed by infusing lidocaine HC1 into the VSA of freely moving conscious rats while the parameters of body temperature, heart rate and mean arterial blood pressure were monitored. Body temperature and cardiovascular parameters were measured in two separate groups of rats. The first set of experiments before brain infusion with lidocaine show that endotoxin has an effect on all of the above parameters. Body temperature showed the typical hypothermic phase followed by an increase to febrile levels in response to injection of endotoxin. Mean arterial blood pressure showed a biphasic response to injection of endotoxin as did heart rate. In the second set of experiments, the animals were injected with endotoxin while the animals received infusion of lidocaine into the VSA/DBB. The results show lidocaine infusion had no significant effect on body temperature, heart rate or mean arterial blood pressure in response to endotoxin. In conclusion the results do not support the idea that the VSA mediates an interaction between body temperature and mean arterial blood pressure, but neither does the data necessarily refute the possibility that the VSA is the site of this interaction.
Hypervelocity Collisions of Binary Stars at the Galactic Centre

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: Recent surveys have identified seven hypervelocity stars (HVSs) in the halo of the Milky Way. Most of these stars may have originated from the breakup of binary star systems by the nuclear black hole SgrA*. In some instances, the breakup of the binary may lead to a collision between its member stars. We examine the dynamical properties of these collisions by simulating thousands of different binary orbits around SgrA* with a direct N-body integration code. For some orbital parameters, the two stars collide with an impact velocity lower than their escape velocity and may therefore coalesce. It is possible for a coalescing binary to have sufficient velocity to escape the galaxy. Furthermore, some of the massive S-stars near Sgr A* might be the merger remnants of binary systems, however this production method can not account for most of the S-stars.

description: A technique for calculation of variability coherence at different timescales performed directly in the time domain is introduced. Simulations are made to compare the coherence spectrum derived by the time domain technique with the coherence function by Fourier analysis. The results indicate that in comparison with the Fourier analysis the time domain technique is more powerful for revealing signal coherence in noisy data. We apply the time domain technique to the real data of the black hole binaries Cygnus X-1 and GX 339-4 and compare the results with their Fourier coherence spectra.

description: We study the relations between the averaged linear entropy production in periodically measured quantum systems and ergodic properties of their classical counterparts. Quantized linear automorphisms of the torus, both classically chaotic and regular ones, are used as examples. Numerical calculations show different entropy production regimes depending on the relation between the Kolmogorov-Sinai entropy and the measurement entropy. The hypothesis of free independence relations between the dynamics and measurement proposed to explain the initial constant and maximal entropy production is tested numerically for those models.

description: We show how to map a given n-qubit target Hamiltonian with bounded-strength k-body interactions onto a simulator Hamiltonian with two-body interactions, such that the ground-state energy of the target and the simulator Hamiltonians are the same up to an extensive error O(epsilon n) for arbitrary small epsilon. The strength of interactions in the simulator Hamiltonian depends on epsilon and k but does not depend on n. We accomplish this reduction using a new way of deriving an effective low-energy Hamiltonian which relies on the Schrieffer-Wolff transformation of many-body physics.

description: Τα δικαιώματα του παιδιού είναι μια έννοια σύμφυτη με την οικουμενική ανθρώπινη φύση. Αυτό σημαίνει ότι θεσμοθετήθηκαν για να προστατεύουν τη ζωή και την αξιοπρέπεια των παιδιών, ανεξαρτήτως κοινωνικών-οικονομικών-πολιτισμικών και άλλων πλαισίων. Η εσωτερική ανομοιογένεια και οι κάθετες διαφοροποιήσεις εντός των κοινοτήτων των Ρομά είναι αναμφισβήτητες. Εντούτοις, οι Ρομά παρουσιάζουν αρκετά κοινά στοιχεία σε βασικές πτυχές της κοινωνικο-οικονομικής τους ζωής και στην ποιότητα των σχέσεών τους με την ευρύτερη κοινωνική εξωομάδα, βιώνοντας πολυεπίπεδα τον κοινωνικό αποκλεισμό. Η γράφουσα, μέσω της ποιοτικής έρευνας πεδίου, επιδιώκει να μελετήσει την επίδραση κοινωνικών-οικονομικών-θεσμικών-πολιτισμικών παραγόντων, στη διαμόρφωση των απόψεων, στάσεων και πρακτικών των Ρομά γονέων, αναφορικά με βασικά δικαιώματα των παιδιών τους. Η διερεύνηση του πρίσματος, υπό το οποίο οι γονείς σκέφτονται και δρουν, συνθέτει μια πιο ολιστική, δομοαιτιακή προσέγγιση του ζητήματος. Η μελέτη της αναγνώρισης ή απόρριψης και εφαρμογής ή παράβλεψης των δικαιωμάτων, σε διαφορετικά πεδία δράσης, αποκτά ιδιαίτερη δυναμική στη σύγχρονη πολυετεροτική κοινωνία. Η ανίχνευση των υβριδικών σχέσεων που δομούνται εντός των πλαισίων αυτών και ο χαρακτήρας, δημοκρατικός ή εξουσιαστικός, που αυτές αποκτούν, αποτελούν το ερμηνευτικό πλαίσιο της εκάστοτε κοινωνικής πραγματικότητας .
description: Children's rights are a concept inherent in the universal human nature. This means, that the rights were established to protect the life and dignity of children, regardless the socio-economic, cultural and other contexts. The internal heterogeneity and the vertical variations within the Roma communities are undeniable. However, in general, Roma have several common characteristics in their lifestyle, in key aspects of socio-economic life and the quality of their relations with the wider social outgroup, multi experiencing social exclusion. The writer, through qualitative field research aims to study the influence of social-economic-cultural-institutional factors in shaping opinions, attitudes and actions of Roma parents, regarding the basic rights of their children. The investigation of their perspectives, in which the parents think and act, constitutes a more holistic structural-reasons approach of the issue. The study of the recognition or rejection and implementation or oversight of the rights in different contexts of action, is particularly dynamic in the contemporary multi-diverse society. The detection of hybrid relationships that are built within different frameworks and the nature, democratic or authoritarian, which they adopt, acquire the interpretative framework of each social reality.

Year: 2024

description: Synchrotrons are a potent tool in generating X-rays, with notable qualities such as brilliance, intensity, extended energy range, and peculiar time structure. Among the diverse experimental techniques utilizing synchrotron radiation, X-ray Absorption Spectroscopy plays a considerable role by providing insights into the local environment of specific chemical species. The local structure plays a crucial role in determining the macroscopic physical properties, namely transport and optics, of materials, including thermoelectric materials. This contribution will revisit the fundamental aspects of synchrotron radiation and highlight key points about X-ray absorption spectroscopy. Finally, the presentation will include examples of the application of XAS in studying thermoelectric materials.

Tα δεδομένα που συλλέχθηκαν από τον ανιχνευτή ATLAS κατά το έτος 2015, αντιστοιχούν σε ολοκληρωμένη φωτεινότητα 3.2 inverse femtobarn για τη διάσπαση δύο μποζονίων Z σε 4 λεπτόνια (ηλεκτρόνια ή μιόνια). Συνολικά, παρατηρούνται 63 γεγονότα δύο μποζονίων Ζ. Η ενεργός διατομή υπολογίζεται αρχικά σε μία “fiducial” περιοχή η οποία συμπίπτει με την πειραματική αποδοχή του ανιχνευτή ATLAS και στη συνέχεια επεκτείνεται στην ολική ενεργό διατομή, λαμβάνοντας υπόψη την θεωρητική αβεβαιότητα. Εν συνεχεία, εξάγονται όρια σε μία από τις παραμέτρους των ανώμαλων τριπλών συζεύξεων μποζονίων, κάνοντας χρήση των γεγονότων της διάσπασης ΖΖ σε 4 λεπτόνια. Η μέτρηση, πραγματοποιείται δημιουργώντας υποπεριοχές (bins) στην κατανομή της αναλλοίωτης μάζας του συστήματος των τεσσάρων λεπτονίων για κάθε γεγονός. Δεν παρατηρείται απόκλιση από τις προβλέψεις του Καθιερωμένου Μοντέλου. Η ενεργός διατομή, όπως επίσης και τα όρια στις ανώμαλες τριπλές συζεύξεις μποζονίων μπορούν να βελτιωθούν, καθώς θα αυξάνεται το δείγμα γεγονότων που συλλέγονται στον ανιχνευτή ATLAS. Τέλος, παρουσιάζεται μια μελέτη ευαισθησίας στον προσδιορισμό των ανώμαλων τριπλών συζεύξεων μποζονίων Ζ συναρτήσει της ολοκληρωμένης φωτεινότητας του δείγματος γεγονότων.
description: The ZZ production cross section measurement in LHC pp collisions at a centre-of-mass energy of 13 TeV is presented. The dataset collected by the ATLAS detector in 2015 corresponds to an integrated luminosity of 3.2 inverse femtobarn and the events are consistent with the decay of two Z bosons to 4 leptons (electrons or muons). In total, we observe 63 ZZ events. The cross section is calculated first in a “fiducial” region that closely matches the experimental acceptance of the ATLAS detector, extrapolating afterwards to total cross section taking into account theoretical uncertainties. Exclusion limits on anomalous triple gauge couplings, are also extracted using events from the decay ZZ to 4 leptons. The measurement is performed by binning the invariant mass distribution of the four-lepton system in each selected event. No deviation from the Standard Model expectation is observed. Both the cross section and the limits on aTGCs can benefit from the increased statistics data sample collected by ATLAS in the future. A sensitivity study on the aTGC limits, as a function of the integrated luminosity is presented

description: Inertia amplification is a mechanism coupling degrees of freedom within a vibrating structure. Its goal is to achieve an apparent high dynamic mass and, accordingly, a low resonance frequency. Such structures have been described for use in locally resonant metamaterials and phononic crystals to lower the starting frequency of a band gap without adding mass to the system. This study shows that any non-linear kinematic coupling between translational or rotational vibrations leads to the appearance of amplitude-dependent damping. The analytical derivation of the equation of motion of a resonator with inertia amplification creates insight in the damping process, and shows that the vibration damping increases with its amplitude. The theoretical study is validated by experimental evidence from two types of inertia-amplification resonators. Finally, the importance of amplitude-dependent damping is illustrated when the structure is used as a tuned mass damper for a cantilever beam.

description: We experimentally demonstrate the coherent manipulation of atomic states in far-detuned dipole traps and registers of dipole traps based on two-dimensional arrays of microlenses. By applying Rabi, Ramsey, and spin-echo techniques, we systematically investigate the dephasing mechanisms and determine the coherence time. Simultaneous Ramsey measurements in up to 16 dipole traps are performed and proves the scalability of our approach. This represents an important step in the application of scalable registers of atomic qubits for quantum information processing. In addition, this system can serve as the basis for novel atomic clocks making use of the parallel operation of a large number of individual clocks each remaining separately addressable.

description: We derive nonlinear wave equations describing the propagation of slowly-varying wavepackets formed by topological valley-Hall edge states. We show that edge pulses break up even in the absence of spatial dispersion due to nonlinear self-steepening. Self-steepening leads to the previously-unattended effect of a gradient catastrophe, which develops in a finite time determined by the ratio between the pulse's nonlinear frequency shift and the size of the topological band gap. Taking the weak spatial dispersion into account results then in the formation of stable edge quasi-solitons. Our findings are generic to systems governed by Dirac-like Hamiltonians and validated by numerical modeling of pulse propagation along a valley-Hall domain wall in staggered honeycomb waveguide lattices with Kerr nonlinearity.

description: The aim of this thesis was to study the cult of Artemis and Hecate and detect the similarities of those two deities. The research framework was set in Greece, during the classical era, because it is marked by a special cultural and religious development. Initially this thesis presents the cults of Artemis and Hecate individually, and the way those were formed in Classical Greece. Subsequently, the relations between those two deities are examined, exploring cases where they are identified and have common reference points. In addition, an analysis is also carried out about Bendis, a deity that constitutes such a common reference point between Artemis and Hecate, due to the fact that she has similarities with each one of them in many cases. Finally, the paper presents their places of worship, using Hecate as the main research basis and the cases where she is associated with Artemis.

description: The aim of the present dissertation was to identify, quote and comment Plato’s views on poetry, especially in “Ion” and “Republic”. Firstly, was presented a brief history about poetry and clarified some certain notions. From early antiquity, we passed in classical antiquity and Plato. After that, outlined the meaning and framework of “Ion” (or “About the Iliad”), Plato’s opinions about poetry, as listed in this book and a summary of the Plato’s work with some main points. In “Republic”, was implemented the same method of analysis, with particular emphasis on the 2nd, 3rd and 10th book.

description: The temperature and magnetic field dependences of the conductivity of the heterostructures with asymmetric In$_x$Ga$_{1-x}$As quantum well are studied. It is shown that the metallic-like temperature dependence of the conductivity observed in the structures investigated is quantitatively understandable within the whole temperature range, $T=0.4-20$ K. It is caused by the interference quantum correction at fast spin relaxation for 0.4 K$ < T < 1.5$ K. At higher temperatures, 1.5 K$4-6$ K, the metallic-like behavior is determined by the phonon scattering.

description: An indirect proton flux measuring tool based on discrimination of the energy deposited by protons in 128 x 128 pixel EIT CCD areas outside the solar disk images is presented. Single pixel intensity events are converted into proton incident energy flux using modeled energy deposition curves for angles of incidence 60 deg in four EIT spatial areas with different proton stopping power. The extracted proton flux is corrected for both the loss of one-pixel events in the range of angles of incidence as well as for the contribution to the single pixel events resulting from scattered middle-energy protons (low-energy or high-energy particles are stopped by the EIT components or pass through them, accordingly). A simple geometrical approach was found and applied to correct for a non-unique relation between the proton-associated CCD output signal and the incident proton energy. With this geometrical approximation four unique proton incident energy ranges were determined as 45--49, 145--154, 297--335, and 390--440 MeV. The indirect proton flux measuring tool has been tested by comparing Solar Energetic Particles (SEP) flux temporal profiles extracted from the EIT CCD frames and downloaded from the GOES database for the Bastille Day (BD) of 2000 July 14 and the more recent 2005 January 20 events. The SEP flux temporal profiles and proton spectra extracted from the EIT in the relatively narrow energy ranges between 45 and 440 MeV reported here are consistent with the related GOES profiles. The four additional EIT extracted ranges provide higher energy resolution of the SEP data.

description: Weak decays in superheavy nuclei with proton numbers Z = 118 - 120 and neutron numbers N = 175 - 184 are studied within a microscopic formalism based on deformed self-consistent Skyrme Hartree-Fock mean-field calculations with pairing correlations. The half-lives of beta+ decay and electron capture are compared with alpha-decay half-lives obtained from phenomenological formulas. The sensitivity of the half-lives to the unknown Q-energies is studied by comparing the results obtained from different approaches for the masses. It is shown that alpha-decay is always dominant in this mass region. The competition between alpha and beta+/EC decay modes is studied in seven alpha-decay chains starting at different isotopes of Z=118, 119, and 120.

Axion Quality Straight from the GUT

Year: 2021

description: Composite axion scenarios offer a robust field theoretic justification for the existence of a Peccei-Quinn symmetry of high quality. We present a new class of realizations that are naturally embedded in Grand-Unified Theories, retain asymptotic freedom for all gauge groups, and protect the axion symmetry up to operators of dimension 12. Our setup leads to a number of distinctive signatures at low energies. First, additional composite scalars are predicted; some of these are viable dark matter candidates for values of the axion decay constant that are too low for the QCD axion abundance to be relevant. Second, an approximate unification of the Standard Model gauge couplings takes place at the axion scale, while leaving the actual quark-lepton unification at much higher energies as usual. This suggests the existence of GUT relics with Standard Model gauge quantum numbers at potentially accessible scales.

description: Because the disc--jet coupling likely depends on various properties of sources probed, the sample control is always an important but challenging task. In this work, we re-analyzed the INTEGRAL hard X-ray-selected sample of Seyfert galaxies. We only consider sources that have measurements in black hole mass, and luminosities in radio and X-rays. Our sample includes 64 sources, consists of both bright AGNs and low-luminosity ones. We first find that, because of the similarity in the $L_{HX}/L_X$ distribution, the X-ray origin of radio-loud Seyferts may be the same to that of radio-quiet ones, where we attribute to the hot accretion flow (or similarly, the corona). We then investigate the connections between luminosities in radio and X-rays. Since our sample suffers a selection bias of a black hole mass $M_{BH}$ dependence on $L_X/L_{Edd}$, we focus on the correlation slope $ξ_X$ between the radio (at 1.4 GHz) and X-ray luminosities in Eddington unit, i.e. $(L_R/L_{Edd})\propto(L_X/L_{Edd})^{ξ_X}$. We classify the sources according to various properties, i.e. 1) Seyfert classification, 2) radio loudness, and 3) radio morphology. We find that, despite these differences in classification, all the sources in our sample are consistent with a universal correlation slope $ξ_X$, with $ξ_X=0.77\pm0.10$. This is unexpected, considering various possible radio emitters in radio-quiet systems. For the jet interpretation, our result may suggest a common/universal but to be identified jet launching mechanism among all the Seyfert galaxies, while properties like black hole spin and magnetic field strength only play secondary roles. We further estimate the jet production efficiency $η_{jet}$ of Seyfert galaxies, which is $η_{jet}\approx1.9^{+0.9}_{-1.5}\times10^{-4}$ on average. We also find that $η_{jet}$ increases as the system goes fainter.

description: The aim of the present thesis was the study of the faulty decisions of the three companies liable by capital that exist in the Greek commercial law. Specifically, we dealt with the faulty decisions of the general meeting of shareholders of the limited company (SA company) and the meeting of partners of the company with limited liability and of the private company liable by capital. We examined and reported with details the three kinds of faulty decisions that may arise in a shareholders’ meeting of the limited company as it has been recently restated by the law 3604/2007 and these are the nonexistent decisions, the void decisions and the voidable decisions. Then we presented the meeting of the partners of the company with limited liability and we examined the faulty decisions of this meeting that may be identified as voidable or void ones. Additionally, we examined in detail the meeting of partners of the private company liable capital and the faulty decisions of this meeting which could referred as either voidable and void, as well as we examined the partners’ decisions taken without meeting.

description: Side-channel attacks are an unpredictable risk factor in cryptography. Therefore, continuous observations of physical leakages are essential to minimise vulnerabilities associated with cryptographic functions. Lightweight cryptography is a novel approach in progress towards internet-of-things (IoT) security. Thus, it would provide sufficient data and privacy protection in such a constrained ecosystem. IoT devices are resource-limited in terms of data rates (in kbps), power maintainability (battery) as well as hardware and software footprints (physical size, internal memory, RAM/ROM). Due to the difficulty in handling conventional cryptographic algorithms, lightweight ciphers consist of small key sizes, block sizes and few operational rounds. Unlike in the past, affordability to perform side-channel attacks using inexpensive electronic circuitries is becoming a reality. Hence, cryptanalysis of physical leakage in these emerging ciphers is crucial. Among existing studies, power analysis seems to have enough attention in research, whereas other aspects such as electromagnetic, timing, cache and optical attacks continue to be appropriately evaluated to play a role in forensic analysis. As a result, we started analysing electromagnetic emission leakage of an ultra-lightweight block cipher, PRESENT. According to the literature, PRESENT promises to be adequate for IoT devices, and there still seems not to exist any work regarding correlation electromagnetic analysis (CEMA) of it. Firstly, we conducted simple electromagnetic analysis in both time and frequency domains and then proceeded towards CEMA attack modelling. This paper provides a summary of the related literature (IoT, lightweight cryptography, side-channel attacks and EMA), our methodology, current outcomes and future plans for the optimised results.
