description: This paper investigates the reinforcement learning (RL) based disturbance rejection control for uncertain nonlinear systems having non-simple nominal models. An extended state observer (ESO) is first designed to estimate the system state and the total uncertainty, which represents the perturbation to the nominal system dynamics. Based on the output of the observer, the control compensates for the total uncertainty in real time, and simultaneously, online approximates the optimal policy for the compensated system using a simulation of experience based RL technique. Rigorous theoretical analysis is given to show the practical convergence of the system state to the origin and the developed policy to the ideal optimal policy. It is worth mentioning that, the widely-used restrictive persistence of excitation (PE) condition is not required in the established framework. Simulation results are presented to illustrate the effectiveness of the proposed method.

description: We present new SOFIA [CII] and ALMA CO(J=1-0) observations of the nearby asymmetric barred spiral galaxy NGC 7479. The data, which cover the whole bar of the galaxy and the counter-arms visible in the radio continuum, are analyzed in conjunction with a wealth of existing visible, infrared, radio, and X-ray data. As in most normal galaxies, the [CII] emission is generally consistent with emission from cooling gas excited by photoelectric heating in photo-dissociation regions. However, anomalously high [CII]/CO ratios are seen at the two ends of the counter-arms. Both ends show shell-like structures, possibly bubbles, in H-alpha emission. In addition, the southern end has [CII] to infrared emission ratios inconsistent with normal star formation. Because there is little HI emission at this location, the [CII] emission probably originates in warm shocked molecular gas heated by the interaction of the radio jet forming the counter-arms with the interstellar medium in the galaxy. At two other locations, the high [CII]/CO ratios provide evidence for the existence of patches of CO-dark molecular gas. The [CII] and CO observations also reveal resolved velocity components along the bar. In particular, the CO emission can be separated into two components associated to gas along the leading edge of the bar and gas trailing the bar. The trailing gas component that amounts to approximately 40% of the gas around the bar region may be related to a minor merger.

description: We investigate the effects of the accretion of phantom energy with non-zero bulk viscosity onto a Schwarzschild black hole and show that black holes accreting viscous phantom energy will lose mass rapidly compared to the non-viscous case. When matter is incorporated along with the phantom energy, the black holes meet with the same fate as bulk viscous forces dominate matter accretion. If the phantom energy has large bulk viscosity, then the mass of the black hole will reduce faster than in the small viscosity case.

description: Deep learning-based support systems have demonstrated encouraging results in numerous clinical applications involving the processing of time series data. While such systems often are very accurate, they have no inherent mechanism for explaining what influenced the predictions, which is critical for clinical tasks. However, existing explainability techniques lack an important component for trustworthy and reliable decision support, namely a notion of uncertainty. In this paper, we address this lack of uncertainty by proposing a deep ensemble approach where a collection of DNNs are trained independently. A measure of uncertainty in the relevance scores is computed by taking the standard deviation across the relevance scores produced by each model in the ensemble, which in turn is used to make the explanations more reliable. The class activation mapping method is used to assign a relevance score for each time step in the time series. Results demonstrate that the proposed ensemble is more accurate in locating relevant time steps and is more consistent across random initializations, thus making the model more trustworthy. The proposed methodology paves the way for constructing trustworthy and dependable support systems for processing clinical time series for healthcare related tasks.

description: This thesis examines and develops knowledge for the design of effective Pictorial Assembly Instructions (PAls). PAls are an important element of products requiring assembly by the consumer as the success of the product relies on the consumer's ability to interpret and enact the instructions correctly. However there is very little research published about their design, particularly with regard to the creation of effective illustrations. The thesis examines the academic literature in the area of pictorial instruction design in western and developing countries. The positivist reductionist approaches used for the research are critiqued and alternative approaches to research appropriate for PAls are presented. The method used for this thesis is one of designerly research to develop grounded theory expressed as a pattern language and concepts. The research is expanded via an examination of existing practice and discussions with practitioners regarding how they develop and encode their knowledge for PAl design. This knowledge is set out as a list of guidelines. A project to design PAls for a flat-pack wheel chair for distribution to developing countries is undertaken to further investigate and develop the knowledge for PAl design. This thesis concludes with a pattern language for PAls and the description of factors to consider in the creation of illustrations for PAls.

description: We explore BPS quivers for D=5 theories, compactified on a circle and geometrically engineered over local Calabi-Yau 3-folds, for which many of known machineries leading to (refined) indices fail due to the fine-tuning of the superpotential. For Abelian quivers, the counting reduces to a geometric one, but the technically challenging $L^2$ cohomology proved to be essential for sensible BPS spectra. We offer a mathematical theorem to remedy the difficulty, but for non-Abelian quivers, the cohomology approach itself fails because the relevant wavefunctions are inherently gauge-theoretical. For the Cartan part of gauge multiplets, which suffers no wall-crossing, we resort to the D0 picture and reconstruct entire KK towers. We also perform numerical checks using a multi-center Coulombic routine, with a simple hypothesis on the quiver invariants, and extend this to electric BPS states in the weak coupling chamber. We close with a comment on known Donaldson-Thomas invariants and on how $L^2$ index might be read off from these.

description: We develop a theoretical formalism to model the linear spectrum of a quantum dot embedded in a high quality cavity, in presence of an arbitrary mechanism modifying the homogeneous spectrum of the quantum dot. Within the simple assumption of lorentzian broadening, we show how the known predictions of cavity quantum electrodynamics are recovered. We then apply our model to the case where the quantum dot interacts with an acoustic-phonon reservoir, producing phonon sidebands in the response of the bare dot. In this case, we show that the sidebands can sustain the spectral response of the cavity-like peak even at moderate dot-cavity detuning, thus supporting recent experimental findings.

description: Recent numerical and theoretical considerations have shown that low-degree acoustic modes in rapidly rotating stars follow an asymptotic formula and recent observations of pulsations in rapidly rotating delta Scuti stars seem to match these expectations. However, a key question is whether strong gradients or discontinuities can adversely affect this pattern to the point of hindering its identification. Other important questions are how rotational splittings are affected by the 2D rotation profiles expected from baroclinic effects and whether it is possible to probe the rotation profile using these splittings. Accordingly, we numerically calculate pulsation modes in continuous and discontinuous rapidly rotating models produced by the 2D ESTER (Evolution STEllaire en Rotation) code. This spectral multi-domain code self-consistently calculates the rotation profile based on baroclinic effects and allows us to introduce discontinuities without loss of numerical accuracy. Pulsations are calculated using an adiabatic version of the Two-dimensional Oscillation Program (TOP) code. The variational principle is used to confirm the high accuracy of the pulsation frequencies and to derive an integral formula that closely matches the generalised rotational splittings, except when modes are involved in avoided crossings. This potentially allows us to probe the the rotation profile using inverse theory. Acoustic glitch theory, applied along the island mode orbit deduced from ray dynamics, can correctly predict the periodicity of the glitch frequency pattern produced by a discontinuity or the Gamma1 dip related to the He II ionisation zone in some of the models. The asymptotic frequency pattern remains sufficiently well preserved to potentially allow its detection in observed stars.

description: Manganese oxide (MnOₓ) is considered a promising material for the oxygen evolution reaction (OER) to replace noble metal catalysts in water splitting. The improvement of MnOₓ requires mechanistic and kinetic knowledge of the four‐electron transfer steps of the OER. X‐ray photoelectron spectroscopy, a widely used tool to characterize the electronic structure of thin films, is used in combination with surface‐enhanced Raman spectroscopy to gain a deeper knowledge of the different mixed MnOₓ types and their respective change in chemical composition. Using Raman spectroscopy during electrochemical measurements, all samples were found to reveal Birnessite‐type MnO₂ motifs in alkaline media at an applied potential. Their activity correlates with two shifting Raman active modes, one of them being assigned to the formation of MnIII species, and one to the expansion of layers of MnO₆ octahedra. A special activation treatment leads independent of the starting material to a highly amorphous mixed‐valence oxide, which shows the highest OER activity.
Antibody targeted liposomal systems

Publisher: name: University of British Columbia

description: Despite success in the development of clinically useful liposomal anticancer drugs, the advancement of targeted formulations has been limited to only a handful of successful studies in animal models of cancer. This thesis suggests that a fundamental lack of understanding of the biological fate of protein-conjugated liposomes has led to the limited success of targeted carriers. Three critical areas of fundamental importance have been identified to better understand the limited success: i) optimizing the physical and chemical attributes of protein targeted liposomal carriers for in vivo applications; ii) evaluation of the biological fate of liposomal carriers; and iii) factors influencing the association of targeting ligands with liposomes. These basic studies identify a number of parameters that will effectively facilitate the development of therapeutically useful targeted liposomes. The initial focus of this investigation was concerned with the rapid aggregation of liposomes that occurs during protein coupling on the liposome surface. By adding polyethylene glycol (PEG)-lipid anchor conjugates onto a liposome, reductions in liposome aggregation were observed. This study demonstrated that incorporation of a 2000 M.W. hydrophilic PEG polymer anchored to a phospholipid in the liposomal membrane at a final concentration of 2 mol% resulted in optimal inhibition of aggregation with no significant inhibition of target site binding and optimal circulation lifetimes. Further investigations focused on passive tumor accumulation of doxorubicin containing liposomes. These studies were completed with the objectives of assessing whether liposomes that reach extravascular spaces within tumors are available for targeting. Finally, experiments focused on the method of coupling antibody to a liposome, either through primary amines or carbohydrates. Results concluded that the conjugation of antibody via carbohydrates resulted in extended circulation lifetimes compared with antibody-conjugated through primary amines. Additional characterization raised concerns as to the stability of the antibody on the liposome in vivo and suggested that the extended plasma levels observed with the carbohydrate conjugated antibodies was a result of antibody instability on the liposome. These studies, therefore, suggest that the method of conjugation of antibody is vital to the circulation lifetimes of antibody-conjugated liposomes and will most certainly be of major importance to the accumulation of liposomes to target sites.

description: GeSn alloys are nowadays considered as the most promising materials to build Group IV laser sources on silicon (Si) in a full complementary metal oxide semiconductor-compatible approach. Recent GeSn laser developments rely on increasing the band structure directness, by increasing the Sn content in thick GeSn layers grown on germanium (Ge) virtual substrates (VS) on Si. These lasers nonetheless suffer from a lack of defect management and from high threshold densities. In this work we examine the lasing characteristics of GeSn alloys with Sn contents ranging from 7 \% to 10.5 \%. The GeSn layers were patterned into suspended microdisk cavities with different diameters in the 4-\SI{8 }{\micro\meter} range. We evidence direct band gap in GeSn with 7 \% of Sn and lasing at 2-\SI{2.3 }{\micro\meter} wavelength under optical injection with reproducible lasing thresholds around \SI{10 }{\kilo\watt\per\square\centi\meter}, lower by one order of magnitude as compared to the literature. These results were obtained after the removal of the dense array of misfit dislocations in the active region of the GeSn microdisk cavities. The results offer new perspectives for future designs of GeSn-based laser sources.

We show that equivariant primary decompositions exist if the group is connected. As main application we consider the case of varieties which are quotients of a quasi-affine variety by the action of a diagonalizable group and thus admit a homogeneous coordinate ring, such as toric varieties. Comparing these decompositions with primary decompositions of graded modules over the homogeneous coordinate ring, we show that these are equivalent if the action of the diagonalizable group is free. We give some specific examples for the case of toric varieties.

description: We present the CHAOS-7 model of the time-dependent near-Earth geomagnetic field between 1999 and 2020 based on magnetic field observations collected by the low-Earth orbit satellites {\it Swarm}, CryoSat-2, CHAMP, SAC-C and Ørsted, and on annual differences of monthly means of ground observatory measurements. The CHAOS-7 model consists of a time-dependent internal field up to spherical harmonic degree 20, a static internal field which merges to the LCS-1 lithospheric field model above degree 25, a model of the magnetospheric field and its induced counterpart, estimates of Euler angles describing the alignment of satellite vector magnetometers, and magnetometer calibration parameters for CryoSat-2. Only data from dark regions satisfying strict geomagnetic quiet-time criteria (including conditions on IMF $B_z$ and $B_y$ at all latitudes) were used in the field estimation. Model parameters were estimated using an iteratively-reweighted regularized least-squares procedure; regularization of the time-dependent internal field was relaxed at high spherical harmonic degree compared with previous versions of the CHAOS model. We use CHAOS-7 to investigate recent changes in the geomagnetic field, studying the evolution of the South Atlantic weak field anomaly and rapid field changes in the Pacific region since 2014. At Earth's surface a secondary minimum of the South Atlantic Anomaly is now evident to the south west of Africa. Green's functions relating the core-mantle boundary radial field to the surface intensity show this feature is connected with the movement and evolution of a reversed flux feature under South Africa. The continuing growth in size and weakening of the main anomaly is linked to the westward motion and gathering of reversed flux under South America.

description: We consider decompositions of processes of the form $Y=f(t,X_t)$ where $X$ is a semimartingale. The function $f$ is not required to be differentiable, so Itô's lemma does not apply. In the case where $f(t,x)$ is independent of $t$, it is shown that requiring $f$ to be locally Lipschitz continuous in $x$ is enough for an Itô-style decomposition to exist. In particular, $Y$ will be a Dirichlet process. We also look at the case where $f(t,x)$ can depend on $t$, possibly discontinuously. It is shown, under some additional mild constraints on $f$, that the same decomposition still holds. Both these results follow as special cases of a more general decomposition which we prove, and which applies to nondifferentiable functions of Dirichlet processes. Possible applications of these results to the theory of one-dimensional diffusions are briefly discussed.

The Lived Experience of UK Forensic Carers of African-Caribbean Heritage Caring for Someone with Psychosis: An Interpretative Phenomenological Analysis

description: For more than six decades, African-Caribbean communities have faced mental health inequalities in the UK. This study focuses on carers of individuals detained in an NHS forensic mental health hospital (FMHH), most specifically on the experience of carers from racialised communities such as African-Caribbean heritage. This is because carers from African-Caribbean heritage are more likely to care for service users who are overrepresented in FMHH and have increased incidence of psychosis across all major psychotic disorders. To date, few studies have focused on forensic carers. The majority of research into caregivers’ experiences supporting a service user with psychosis in forensic settings has focused on caregivers who were white European parents, mostly mothers, and therefore the evidence base is built on a particular political, economic and social and cultural context.

Therefore, the present qualitative study aimed to explore the lived experience of forensic carers of African-Caribbean heritage who support an individual with psychosis in an FMHH. Seven participants were purposively recruited and participated in semi-structured interviews. An interpretative phenomenological analysis found four superordinate themes: 1) The role is “too much for humanity”: Emotional, physical and relational challenges, 2) Cultural and Community – Norms and Values, 3) It is a Terrible Battle Relating to Services and Professionals and 4) Ways to Survive the Emotional Demands of the Role.

The findings highlighted participants’ caregiving roles impacted various aspects of their lives. Also, participants’ caregiving behaviour and attitude within FMHH were influenced by culture and the social-political context of living in the UK. Furthermore, participants’ relationship with forensic services and professionals was problematic, overshadowed by fear and mistrust given their experience of institutional racism. Additionally, a lack of information and power imbalance between carers, professionals and services acted as barriers to adequate care within FMHH. Caregivers used several strategies to survive the emotional demand of the role.

It is crucial that the needs and values of this group of carers are recognised to offer services tailored to cultural, political, and social contexts. Implications for clinical practice, service delivery, strengths, and limitations as well as future research directions are discussed within these contexts.

description: Exact solutions of the Einstein field equations with cosmic string and space varying cosmological constant, viz., $Λ= Λ(r)$, in the energy-momentum tensors are presented. Three cases have been studied: where variable cosmological constant (1) has power law dependence, (2) is proportional to the string fluid density, and (3) is purely a constant. Some cases of interesting physical consequences have been found out such that (i) variable cosmological constant can be represented by a power law of the type $Λ=3r^{-2}$, (ii) variable cosmological constant and cosmic string density are interdependent to each other according to the relation $Λ=-8πρ_s$, and (iii) cosmic string density can be scaled by a power law of the type $ρ_s=r^{-2}$. It is also shown that several known solutions can be recovered from the general form of the solutions obtained here.

description: Reinforcement learning deals with the problem of sequential decision making in uncertain stochastic environments. In this thesis I deal with agents who attempt to solve the reinforcement learning problem online and in real-time. This presents experimental challenges for which I introduce novel kernelised algorithms. Kernel algorithms are very useful in reinforcement learning settings as they enable learning in situations where a very high-dimensional or hand engineered feature vector would otherwise be required. Furthermore, I attempt to address the theoretical challenges which arise from online on-policy algorithms, for which I introduce a type of analysis which is novel (and useful) to reinforcement learning in its lack of restrictive assumptions on the behaviour policy. I will introduce three novel algorithms attempting to advance the areas of kernel, empirical and theoretical reinforcement learning. The first of these algorithms presents a kernel extension of SARSA for its empirical properties - namely its incorporation of eligibility traces with sparse kernel algorithms. I then present a model-free/model-based ensemble which use gradient based methods for online learning. I present them with regret analysis which enables an analysis of the value functions learned with no probabilistic assumptions, and hence no assumptions on the behaviour policy. Along the way I also make a novel "sub-contribution", namely non-squared loss functions for reinforcement learning. The use of different loss functions constitutes a running theme through the algorithms I introduce, as I show that various non-traditional (to reinforcement learning) loss functions can be useful for both efficiency of the algorithm, and for accuracy by ensuring smooth function approximations. I present thorough experimental and theoretical analyses along the way.

description: Η συγκεκριμένη εργασία παρουσιάζει την ιστορία της γυναικείας εκπαίδευσης στην Κρήτη από τις αρχές του 19ου αιώνα έως το τέλος της Κρητικής Πολιτείας (1913). Η περίοδος αυτή που αρχίζει από τα προεπαναστατικά χρόνια και τελειώνει με την Ενωση της Κρήτης με την Ελλάδα, σηματοδοτείται από έντονες πολιτικοκοινωνικές ζυμώσεις που επηρεάζουν τόσο το χώρο της εκπαίδευσης όσο και τη θέση της γυναίκας στην κοινωνία της εποχής. Η διάρθρωση της εργασίας γίνεται σε δύο κύρια μέρη, όπου στο πρώτο μέρος εξετάζεται η περίοδος από το 1800 έως το 1897, οπότε και σηματοδοτείται το τέλος της ημιαυτονομίας στη Νήσο, και στο δεύτερο μέρος μελετάται η περίοδος της Κρητικής Πολιτείας η οποία αρχίζει το 1898 και τελειώνει με την Ενωση της Κρήτης με το Επίσημο ελληνικό κράτος. Στο προαναφερόμενο ιστορικό πλαίσιο παρουσιάζεται μια συνολική εικόνα της γυναικείας εκπαίδευσης που καλύπτει όλες τις εκπαιδευτικές βαθμίδες μέσα από την εξέταση της σταδιακής ανάπτυξης του σχολικού δικτύου των κοριτσιών και σκιαγραφείται η διαμορφούμενη γυναικεία ταυτότητα μέσα από την εξέταση των σκοπών της εκπαίδευσης.
description: This specific work refers to the history of woman's education in Crete from the beginning of the 19nth century until the end of Cretan State. This period which starts from the first years of revolution and ends with the unification of Crete with the official Greek State is defined from intense social and political fermentations which influence the education and the woman's position alike in the society of that time. The organization of work consists from two major parts where the first part is examined the period from 1800-1897 in which marked the end of semiautonomy of the Cretam State in the island and at the second part the period of the Cretan State is examined from 1898 until the unification of Crete with the official Greek State. At the premetioned historical frame, a total view is presented for the female education which covers all the educational stages through the examination of the gradual development of the female school network and describes the changing female education system through the examination of female identity in the purposes of educational system.
Boundary Liouville Theory: Hamiltonian Description and Quantization

description: The paper is devoted to the Hamiltonian treatment of classical and quantum properties of Liouville field theory on a timelike strip in 2d Minkowski space. We give a complete description of classical solutions regular in the interior of the strip and obeying constant conformally invariant conditions on both boundaries. Depending on the values of the two boundary parameters these solutions may have different monodromy properties and are related to bound or scattering states. By Bohr-Sommerfeld quantization we find the quasiclassical discrete energy spectrum for the bound states in agreement with the corresponding limit of spectral data obtained previously by conformal bootstrap methods in Euclidean space. The full quantum version of the special vertex operator $e^{-ϕ}$ in terms of free field exponentials is constructed in the hyperbolic sector.

Synthetic Approaches to the Macrocyclic Natural Product Tripartilactam
Creators: name: Vo, Yen Thi Hoang
Publisher: name: The Australian National University

description: In 2012 Oh and co-workers reported the isolation of the tricyclic macrolactam tripartilactam from a Streptomyces sp. found in the brood ball of the dung bettle Copris tripartitus. The compound proved to be a moderate inhibitor of sodium/potasium ATPase. The unique and rather complex structure embodies a cyclobutane fused, on its opposing faces, to both an 8- and an 18-membered ring. These architecturally novel features prompted the author to pursue a total synthesis of it. Chapter One provides a brief introduction to the isolation, structural elucidation and proposed biogenesis of tripartilactam. This section also provides details of selected organic reactions that played important roles in the synthetic studies of the author, in particular the Stille cross-coupling, olefin metathesis and olefination reactions. Chapter Two describes two distinct sets of manipulations of the enantiomerically pure chloro cis-1,2-dihydrocatechol, readily obtained through the whole-cell biotransformation of chlorobenzene, into a terminal allene/carbonyl-conjugated alkene and a polyoxygenated cyclooctenone embodying the Eastern Hemisphere of the non-natural enantiomeric form of tripartilactam. Attempts to elaborate these intermediates to the bicyclo[6.2.0]decane system via both intra- and inter-molecular [2+2]-cycloaddition reactions are also discussed. The research detailed in Chapters Three, Four and Five are focused on the synthesis of a macrolactam that it was thought could engage in a transannular [2+2]-cycloadditon reaction and thus mimicking the final step in the proposed biogenesis of tripartilactam. A macrolactone was identified as a potential precursor to tripartilactam and attempts to prepare the former compound are described in Chapter Six.
Collecting data with a mobile phone: Studies of mechanical laws such as energy and momentum conservation

description: We use videos taken with a mobile phone to study conservation of energy, conservation of momentum, and the work-energy theorem by analyzing the collision of a cue ball and the eight ball. A video of the full time sequence, starting from before the cue ball is struck until well after the collision, is recorded with a mobile phone. The video is imported into Origin (free to teachers and students taking a class) [OriginLab Corporation, Origin, Version 2020 (OriginLab Corporation, Northampton, MA, USA, 2020)], where the coordinates of the balls are digitized frame-by-frame using the free Video Extractor app. From these data, the velocities are determined as a function of time and used to determine the energy and momentum of each ball. The data suggest that the balls slip through part of their motion when rotating at an angular velocity different than the rolling angular velocity, so angular momentum and frictional torque must be considered. Such experiments require no specialized equipment other than a device to take a video, and the act of digitizing the data provides the student with visual reinforcement of the physics. Experimentation by students outside of campus can be fun for them and provides a useful alternative to classes when in-lab experiments are not practical. Use of a mobile phone in this way is generally applicable to any other mechanical phenomena that involve motion.

description: Η παρούσα διπλωματική εργασία αφορά στην επανάληψη της ποινικής διαδικασίας εφόσον προκύψουν νέα και άγνωστα γεγονότα ή αποδείξεις. Αναλύει τις προϋποθέσεις ανατροπής μιας αμετάκλητης καταδικαστικής αποφάσεως υπέρ εκείνου που αδίκως υπέστη ποινική κύρωση. Το μεγαλύτερο μέρος της εργασίας καταλαμβάνει μια λεπτομερής καταγραφή σχετικά με το τί συνιστά νέο κι άγνωστο γεγονός ή απόδειξη στο Ποινικό μας Δίκαιο, κυρίως μέσα από σχολιασμό της πλούσιας νομολογίας μας. Επιπλέον, αναφέρονται τόσο η νομική φύση όσο και η περαιτέρω διαδικασία που ακολουθείται, εφόσον η αίτηση του αδίκως καταδικασθέντος γίνει δεκτή, ώστε με την ανάγνωση της εργασίας να διαμορφώνεται μια ολοκληρωμένη αντίληψη σχετικά με το θεσμό της επανάληψης της διαδικασίας του άρθρου 525§1 περ.2 του Κώδικα Ποινικής Δικονομίας.
description: This diplomatic essay concerns to the repetition of the penal procedure provided that new and unknown facts or evidence emerge. It analyses the terms of inversion of an irrevocable condemnatory decision in favour of the one, who was unjustly submitted to penal ratification. The vast part of the essay is occupied by a detailed recording in relation to what constitutes new and unknown fact or evidence according to the Greek Criminal Law, mainly through annotation of our prolific case law. Furthermore, the legal nature and the further process that is followed if the petition of the one who was wrongfully sentenced is accepted are also reported in this essay, so that with its' reading a completed preception is shaped in regards to the institution of the article 525§1 case 2 of the Greek Penal Procedure Code.
Spiky strings, light-like Wilson loops and pp-wave anomaly

description: We consider rigid rotating closed strings with spikes in AdS5 dual to certain higher twist operators in N=4 SYM theory. In the limit of large spin when the spikes reach the boundary of AdS5, the solutions with different numbers of spikes are related by conformal transformations, implying that their energy is determined by the same function of the `t Hooft coupling f(lambda) that appears in the anomalous dimension of twist 2 operators or in the cusp anomaly. In the limit when the number of spikes goes to infinity, we find an equivalent description in terms of a string moving in an AdS pp-wave background. From the boundary theory point of view, the corresponding description is based on the gauge theory living in a 4d pp-wave space. Then, considering a charge moving at the speed of light, or a null Wilson line, we find that the integrated energy momentum tensor has a logarithmic UV divergence whose coefficient we call the "pp-wave anomaly". The AdS/CFT correspondence implies that, for N=4 SYM, this pp-wave anomaly should have the same value as the cusp anomaly. We verify this at lowest order in SYM perturbation theory. As a side result of our string theory analysis, we find new open string solutions in the Poincare patch of the standard AdS space which end on a light-like Wilson line and also in two parallel light-like Wilson lines at the boundary.
