description: H παρούσα μεταπτυχιακή εργασία ασχολείται με την ανάπτυξη της πολιτικής των ΗΠΑ, της σκέψης και της κατανόησης των αμερικανών διπλωματών για τη Μακεδονία και το Μακεδονικό Ζήτημα από το 1944 έως το 1950. Βασίζεται στη δημοσιευμένη συλλογή Foreign Relations of the United States, στις μικροταινίες του State Department, που ανήκουν στο Ιστορικό Αρχείο του Ιδρύματος Μελετών Χερσονήσου του Αίμου, και σε άλλες πρωτεύουσες και δευτερεύουσες πηγές. Στη μελέτη παρακολουθείται η εξέλιξη της αμερικανικής εξωτερικής πολιτικής και στρατηγικής και οι επιρροές που δέχτηκαν κατά τη διάρκεια της δεκαετίας του 1940. Αναλύεται η επιδίωξη της Ουάσιγκτον για διατήρηση της ελληνικής εδαφικής ακεραιότητας και η σημασία που απέδιδε στη Μακεδονία. Επιπρόσθετα, εξετάζεται η κλιμάκωση του Ψυχρού Πολέμου, η παρέμβαση των Ηνωμένων Πολιτειών και των Ηνωμένων Εθνών στην Ελλάδα και οι ερμηνείες που απέδιδαν οι Αμερικανοί στις κομμουνιστικές ενέργειες και το Μακεδονικό Ζήτημα. Επιπλέον, η εργασία πραγματεύεται την αναβάθμιση του Μακεδονικού από ζήτημα της ελληνικής μόνο ασφάλειας σε ζήτημα και της γιουγκοσλαβικής μετά τη ρήξη Βελιγραδίου-Μόσχας. Τέλος, ασχολείται με την υποβάθμιση του Μακεδονικού Ζητήματος από την Ουάσιγκτον και την ανάγκη συνεργασίας Γιουγκοσλαβίας-Ελλάδας.
description: The present master thesis deals with the development of US policy and American diplomats’ thinking and understanding on Macedonia and the Macedonian Question from 1944 to 1950. It is based on the collection of Foreign Relations of the United States, the microfilms of the State Department, part of the Historical Archive of the Institute for Balkan Studies, and other primary and secondary sources. The study follows the evolution of U.S. foreign policy and strategy and the influences that shaped them during the 1940s. Analyses the pursuit of Washington to maintain the Greek territorial integrity and the importance attributed in Macedonia. It also examines the escalation of the Cold War, the intervention of the United States and the United Nations in Greece and interpretations attributing to communist activities and the Macedonian Question by the Americans. Furthermore, the thesis discusses the upgrade of the Macedonian Question from a solely Greek security issue to a Yugoslav one too after the breech between Belgrade and Moscow. Finally, it deals with the degradation of the Macedonian Question by Washington and the need for cooperation between Yugoslavia and Greece.

description: We show that isotropic component of circular polarization of stochastic gravitational wave background can be explored by breaking two dimensional configuration of multiple laser interferometers for correlation analysis. By appropriately selecting orbital parameters for the proposed BBO mission, the circular polarization degree Pi can be measured down to Pi ~ 0.08 (10^{-15}/Omega_{GW})(SNR/5) with slightly (~10%) sacrificing the detection limit for the total intensity Omega_{GW} compared to the standard plane symmetric configuration. This might allow us to detect signature of parity violation in the very early universe.

personal identity
causation

description: Hume discusses personal identity in the main body of the Treatise in Section 6 of Part IV of book 1 and in an appendix published a year later. Hume’s empiricism asserts no idea without a corresponding sense impression. The problem is that the self is not derived from any impression. Do we have an idea of an enduring self? From what impression could this idea be derived? Hume concludes that there is no genuine idea of self, because there is no impression from which such an idea could be derived. A person is a set of perceptions and these perceptions replace one another with rapidity. He fails to find anything but perception. For the idea of identity is that of an object, that ‘remains invariable and uninterrupted through a supposed variation of time’. There are only three relations that can produce a ‘union in the imagination’ between ideas: resemblance, contiguity and causation’. In his Appendix Hume confesses that his theory of personal identity seems to understate the strength of the connections between the impression and the ideas that constitute a single mind. Ultimately, the problem of personal identity becomes the problem of what makes a letter person numerically identical with an earlier person.
description: To κείμενο του Χιουμ που μιλάει για την προσωπική ταυτότητα, όπως και έτσι τιτλοφορείται από τον ίδιο, βρίσκεται στο τέταρτο μέρος του α’ τόμου του έργου του για την Ανθρώπινη Φύση και στο Επίμετρο, το οποίο εκδόθηκε ένα χρόνο αργότερα. Η πρόταση του Χιουμ είναι ότι σε κάθε ιδέα αντιστοιχεί μια εντύπωση. Όταν έχουμε μια ιδέα πρέπει να ψάξουμε ποια είναι η εντύπωση που της αντιστοιχεί. Το πρόβλημα είναι ότι ο εαυτός δεν προέρχεται από καμία τέτοια εντύπωση. Έχουμε, άραγε, την ιδέα ενός διαρκούς εαυτού; Από ποια εντύπωση θα μπορούσε να προέρχεται αυτή η ιδέα; Ο Χιουμ ισχυρίζεται ότι δεν υπάρχει η ιδέα του εαυτού. Το άτομο είναι μια δέσμη αντιλήψεων και αυτές αντικαθίστανται η μία με την άλλη με ταχύτητα. Αποτυγχάνει να βρει τίποτα άλλο πέρα από αντιλήψεις. Η ιδέα της ταυτότητας είναι κάτι που ‘παραμένει αδιάκοπο και αμετάβλητο μέσα από μια υποτιθέμενη αλλαγή στο χρόνο’. Υπάρχουν μόνο τρεις σχέσεις που παράγουν την ενότητα στη φαντασία ανάμεσα στις ιδέες: η ομοιότητα, η συνάφεια στο χώρο και το χρόνο και η αιτιότητα. Στο Επίμετρο ομολογεί ότι η θεωρία για την προσωπική ταυτότητα φαίνεται να έχει υποτιμήσει τη δύναμη των συνδέσεων μεταξύ των εντύπωση και ιδεών που αποτελούν ένα ενιαίο μυαλό. Τελικά, το πρόβλημα της ταυτότητας γίνεται το πρόβλημα του τι κάνει ένα γηραιότερο πρόσωπο αριθμητικά ταυτόσημο με ένα νεότερο.
Aluminum chemistry of selected podzols in Southwestern British Columbia
Creators: name: Yuan, Guodon
Publisher: name: University of British Columbia
Year: 2009

description: Three related aspects of A1 chemistry of selected Humo-Ferric Podzols in Southwestern British Columbia were investigated: mechanisms of podzolization, acidity transfer from soils to surface waters, and phosphate status in relation to soil acidification. Distributions of A1 and Fe in horizons and results of column leaching studies revealed that Al behaves differently from Fe in podzolization in terms of ease of eluviation from the top horizon and illuviation into underlying horizons. This may be thermodynamically explained by the solubility products of Al-bearing minerals and stability constants of A1-organic complexes. This result differs from the traditional belief that A1 and Fe behave similarly in podzolization. Both organic and inorganic mechanisms of podzolization are proposed in the literature. Studies reported are in support of either one or the other mechanism. Chemical extraction results in this study showed that the content of A1 in proto-imogolite was significant in some Bf horizons. This may indicate the contribution of an inorganic mechanism in podzolization. The competition among A1-O-Si, A1-O-C, and A1-O-H bonds, which determined the proportion of inorganic and organic processes, was related to annual precipitation and pH, but not influenced directly by dissolved organic carbon content. Podzol formation is a natural process of soil acidification. This study suggested that the amorphous A1 (A1₀) content in soil might be used as a capacity factor to characterize acidity transfer from soils to surface waters. A1 activity in neutral salt extracts of soils, which represents the amount of A1 subject to transfer to surface waters in situations with little organic and mineral acid input to soils, correlates significantly with A1₀. This A1 activity can be described by an exchange model. A parameter in the model has an empirical relationship with organicbound A1 content. Al concentration in simulated leachates, indicating the amount of A1 transferable to surface waters in situations where soils receive acidic inputs from natural and anthropogenic sources, is much higher than that in neutral salt extracts and is related to A1₀. Exposure of Bf horizons to the land surface may contribute to accelerating transfer of acidity to surface waters. Reduction in bioavailability of phosphorus is a phenomenon during soil acidification. Phosphate sorption parameters were strongly dependent on amorphous A1, Fe, and other constituents. Amorphous A1 and Fe can be used to predict phosphate sorption capacity of the soils. Two European-derived models were shown to be applicable in the areas of this study. Modification was done to include native sorbed phosphate in the sorption capacity of the models.

description: Large language models have become increasingly difficult to train because of the growing computation time and cost. In this work, we present SRU++, a highly-efficient architecture that combines fast recurrence and attention for sequence modeling. SRU++ exhibits strong modeling capacity and training efficiency. On standard language modeling tasks such as Enwik8, Wiki-103 and Billion Word datasets, our model obtains better bits-per-character and perplexity while using 3x-10x less training cost compared to top-performing Transformer models. For instance, our model achieves a state-of-the-art result on the Enwik8 dataset using 1.6 days of training on an 8-GPU machine. We further demonstrate that SRU++ requires minimal attention for near state-of-the-art performance. Our results suggest jointly leveraging fast recurrence with little attention as a promising direction for accelerating model training and inference.

description: One-dimensional (1D) metal-dielectric (MD) periodic structures take advantage of large refractive index contrast between metal and dielectrics to invoke extremely high nonlinear ultrafast responses of metal. These structures are also special due to their extremely high laser damage threshold. The Bragg like 1D MD structure (Ag/SiO2)4 enables strong optical field confinement with much enhanced nonlinear features as compared to simple metal or single (Ag/SiO2)1 structure. In the present work, the ultrafast nonlinear optical responses of the above structures are investigated via femtosecond broadband optical pump-probe technique. The enhanced nonlinear optical absorption is of reverse saturation of absorption (RSA) nature, resulted due to free-carrier absorption (FCA) and excited-state absorption (ESA) processes. The spectral nonlinearities are closely related to the pump-induced modification of the metal's dielectric functions, which are qualitatively visualized by transfer matrix and two-temperature models. The ultrafast temporal evolution of nonlinear absorption clearly demonstrated enhanced optical nonlinearity, disentangled by the electron-electron and electron-phonon dynamic interactions at picosecond time scales. A phenomenological pulse propagation model is employed that incorporates the experimentally obtained nonlinear absorption coefficients and different nonlinear effects exhibited by the system. Nonlinearity plays a crucial role in controlling the ultrafast pulse propagation and could open a new window for many nonlinear device applications. The findings of these new optical materials could possibly pave the way for promising applications in ultrafast photonics.

Parent participation in career planning for adolescents with visual impairments
Creators: name: McConnell, John David
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to investigate a program model in which parents and adolescents examine personal values, career decisions and plans. The subjects were visually impaired students enrolled in regular secondary school and their parents. Twenty volunteer adolescents with visual impairments and their parents from 18 school districts in the province of British Columbia participated in the study. The program consisted of four Partner’s Program (Cochran, 1985) booklets: a parent guideline manual, activity self-exploration exercises, career decisions framework, and a planning workbook designed to facilitate parent involvement in career development activities. Two special career reference publications which described a variety of occupations and necessary adaptations and technical devices designed for individuals with visual impairment were also included. These materials were presented in audio tape, large print and braille. Adolescent subjects and their parents were randomly assigned to two experimental groups. Each group received materials and were given five weeks to complete the program. The Career Decision Scale (Osipow, 1976), Parent Adolescent Communication Scale (Barnes & Olson, 1982), and Career Salience Scale (Greenhaus, 1971, 1977) were employed. All participants were interviewed following the program. A multivariate analysis of variance was computed, and the combined five dependent variables were significantly affected between groups upon completion of the program by the first group. The combined dependent variables were significantly affected again with the second group upon completion of the program. Examination of effect sizes for each dependent variable attributed the differences to gains in measures of career planning and career salience and a decline in career indecision. The effects on the measures of communication were inconclusive. The results indicated that students in both experimental groups confirmed their career choices and became more aware of personal career values. The subjects felt they were encouraged to plan and prepare for a career, explore options, and consider their visual disabilities. Career planning was deemed important by all participants. The importance of work and career were confirmed for participants. Students’ attitudes improved with confirmation of plans and career alternatives. The effects of the program in career development of adolescents with visual impairments and the importance of parent-student communication were positive. The comments of the parents suggested that they had acquired understanding of their child’s career choices.

description: We have studied the mesoscopic shape fluctuations in aligned multilamellar stacks of DMPC bilayers using the neutron spin-echo technique. The corresponding in plane dispersion relation $τ^{-1}$(q$_{||}$) at different temperatures in the gel (ripple, P$_{β'}$) and the fluid (L$_α$) phase of this model system has been determined. Two relaxation processes, one at about 10ns and a second, slower process at about 100ns can be quantified. The dispersion relation in the fluid phase is fitted to a smectic hydrodynamic theory, with a correction for finite q$_z$ resolution. We extract values for, the bilayer bending rigidity $κ$, the compressional modulus of the stacks $B$, and the effective sliding viscosity $η_3$. The softening of a mode which can be associated with the formation of the ripple structure is observed close to the main phase transition.

description: We present experimental results obtained from photoionization and photodissociation processes of abundant interstellar methanol (CH$_3$OH) as an alternative route for the production of H$_3^+$ in dense clouds. The measurements were taken at the Brazilian Synchrotron Light Laboratory (LNLS) employing soft X-ray and time-of-flight mass spectrometry. Mass spectra were obtained using the photoelectron-photoion coincidence techniques. Absolute averaged cross sections for the production of H$_3^+$ due to molecular dissociation of methanol by soft X-rays (C1s edge) were determined. The H$_3^+$'s photoproduction rate and column density were been estimated adopting a typical soft X-ray luminosity inside dense molecular and the observed column density of methanol. Assuming a steady state scenario, the highest column density value for the photoproduced H$_3^+$ was about 10$^{11}$ cm$^2$, which gives the ratio photoproduced/observed of about 0.05%, as in the case of dense molecular cloud AFGL 2591. Despite the small value, this represent a new and alternative source of H$_3^+$ into dense molecular clouds and it is not been considered as yet in interstellar chemistry models.

description: We propose a new method for the discrimination of sub-micron nuclear recoil tracks from an instrumental background in fine-grain nuclear emulsions used in the directional dark matter search. The proposed method uses a 3D Convolutional Neural Network, whose parameters are optimised by Bayesian search. Unlike previous studies focused on extracting the directional information, we focus on the signal/background separation exploiting the polarisation dependence of the Localised Surface Plasmon Resonance phenomenon. Comparing the proposed method with the conventional cut-based approach shows a significant boost in the reduction factor for given signal efficiency.

description: Future products will require new forming processes in order to meet the increasing requirements for innovative products. These processes will enable new possibilities in product manufacturing and the control of product properties beyond geometry control. For this purpose, a new process called punch-hole-rolling has been developed, which enables the production of a double-sided collar in thin sheet structures. Punch-hole-rolling is a two-stage process combination of conventional shear cutting and novel rolling which is carried out in one tool. The process combination allows to derive product data from the punching process for the control of the flexible hole-rolling in order to control product properties such as geometry, hardness and microstructure. In order to increase the process understanding and classification, an FE-simulation is built and validated by experiments.

description: We present long-term (~10^4 M) axisymmetric simulations of differentially rotating, magnetized neutron stars in the slow-rotation, weak magnetic field limit using a perturbative metric evolution technique. Although this approach yields results comparable to those obtained via nonperturbative (BSSN) evolution techniques, simulations performed with the perturbative metric solver require about 1/4 the computational resources at a given resolution. This computational efficiency enables us to observe and analyze the effects of magnetic braking and the magnetorotational instability (MRI) at very high resolution. Our simulations demonstrate that (1) MRI is not observed unless the fastest-growing mode wavelength is resolved by more than about 10 gridpoints; (2) as resolution is improved, the MRI growth rate converges, but due to the small-scale turbulent nature of MRI, the maximum growth amplitude increases, but does not exhibit convergence, even at the highest resolution; and (3) independent of resolution, magnetic braking drives the star toward uniform rotation as energy is sapped from differential rotation by winding magnetic fields.

The molecular pathology of lecithin : cholesterol acyltransferase deficiencuy
Creators: name: Hill, John Stuart
Publisher: name: University of British Columbia
Year: 2009

description: Epidemiological studies have indicated that decreased levels of plasma HDL are associated with an increased risk of coronary artery disease. However, there are several rare familial disorders of HDL metabolism in which, despite very low levels of HDL cholesterol, affected individuals do not appear to be at an increased risk for premature atherosclerosis. Examples of such disorders include familial LCAT deficiency and fish eye disease which are rare autosomal recessive diseases associated with inherited defects within the gene coding for lecithin:cholesterol acyltransferase (LCAT). In both cases, corneal opacities and a severe HDL deficiency are characteristic features of the disease. However, unlike fish eye disease, familial LCAT deficiency is associated with severe lipoprotein abnormalities and additional clinical symptoms including hemolytic anemia, proteinuria and a progressive renal insufficiency. The basis for this segregation is believed to be a result of functional differences associated with the LCAT enzyme. The main purpose of this thesis was to define the molecular basis for the clinical and biochemical heterogeneity observed for different genetic defects of LCAT. To achieve this, the expression of recombinant LCAT (rLCAT) in mammalian cell culture was established as a model to analyse the properties of human plasma LCAT. Subsequently, a series of natural mutations associated with familial LCAT deficiency and fish eye disease were re-created and expressed in both monkey kidney COS-1 and baby hamster kidney cell lines. To determine the functional significance of each mutation, the specific activity of different mutant enzymes was analysed using both synthetic and natural substrates. A wide range of functional abnormalities were identified: (i) defects of secretion, (ii) loss of activity against HDL, (iii) loss of activity against all lipoproteins and (iv) variable reactivities for all lipoproteins. For defects which occur in the homozygous form, the properties of most mutant rLCATs were consistent with the biochemical phenotype observed in the plasma of affected probands. The recreation and analysis of single mutations associated with compound heterozygous genotypes revealed that the products of each allele pair had different characteristics. In addition, the results suggested that the presence of only a single allele coding for a partially active LCAT is sufficient to maintain normal rates of cholesterol esterification. From these biochemical analyses, it appears that LCAT has at least two functionally important domains, the catalytic center and a recognition site for HDL substrates. In conclusion, it seems that the original families identified with familial LCAT deficiency and fish eye disease represent the clinical and biochemical extremes of a wide range of defects of LCAT function. Consequently, these disorders should not be classified as separate diseases but thought of as part of a larger group of LCAT deficiency syndromes.

Πηγή των δεδομένων αποτελούν οι βάσεις Klems, Ameco και World Bank. Τα εμπειρικά αποτελέσματα έδειξαν ότι είναι αυτονόητη η διάκριση της παραγωγικής και μη παραγωγικής εργασίας σε μια οικονομία καθώς η κατανομή της συνολικής οικονομικής δραστηριότητας σε παραγωγικές και μη, καθορίζει το δυνητικά διαθέσιμο για τη συσσώρευση κεφάλαιο, καθώς και τις μακροχρόνιες παραγωγικές δυνατότητες της οικονομίας
description: This paper deals with one of the most important issues of economic and Marxist theory, concerning the division of labor in productive and non-productive. The purpose of the empirical estimates was the role of the distinction of productive and unproductive labor in the evolution of macroeconomic variables, as well as the empirical relationship between Marxist categories and orthodox categories. The empirical study of data is based on the studies of Shaikh and Tonak (1994) and Tsaliki and Tsoulfidis (2012). Also it is attempted to study the basic Classical macroeconomic variables based on the empirical data of the Greek economy. The analysis deals with the Greek economy over the period 1980-2007, during which it was examined the net added value, the variable capital, the surplus value, the rate of surplus value, the ratio of profits - wages, the rate of profit and net investment. The source of data is based on Klems, Ameco and World Bank. The empirical results showed that the distinction of productive and unproductive labor in an economy is self-evident, since the distribution of total economic activity in a productive and unproductive labor sets the potentially available capital for accumulation and the long-term productive capacity of the economy.

description: The study of correlations among particles produced in different rapidity regions may provide understanding of the mechanisms of particle production. Correlations that extend over a longer range are observed in hadron-hadron interactions only at higher energies. Results for short and long-range multiplicity correlations (Forward-Backward) are presented for Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The growth of long range correlations are observed as a function of the pseudorapidity gap in central Au+Au collisions. The Dual Parton model and Color Glass Condensate phenomenology have been explored to understand the origin of long range correlations.

Τις ημέρες και του μήνες που ακολούθησαν μετά το ατύχημα στην Ιαπωνία, πλήθος επιστημονικών ομάδων ανά το κόσμο πραγματοποίησαν μετρήσεις της ραδιενέργειας περιβάλλοντος.Οι μετρήσεις αυτές, οι οποίες δημοσιεύθηκαν σε έγκυρα επιστημονικά περιοδικά, συγκεντρώθηκαν, καταγράφηκαν και παρουσιάζονται παρακάτω. Στόχος της εργασίας ήταν η καταγραφή των επιπέδων ραδιενέργειας σε διάφορες γεωγραφικές θέσεις και ο προσδιορισμός των διαδρομών που ακολούθησε το ραδιενεργό νέφος.Τα ραδιενεργά ισότοπα που επιλέξαμε για να καταλήξουμε στα συμπεράσματα μας ήταν το 133Xe, το 134Cs, το 137Cs, το 131I καθώς και το κοσμογενετικής προέλευσης 7Be.
description: In this paper we dealt with the concentration levels of radioactive contaminants in the air after the nuclear accident in Fukushima. The days and months that followed the accident in Japan, numerous scientific groups around the world have made measurements of environmental radioactivity. These measurements, which were published in scientific journals, collected, recorded and presented below. Objective of this work was to evaluate the levels of radioactivity in different geographical locations and identify paths followed by the radioactive fallout. We have chosen five radioactive isotopes to come to our conclusions 133Xe, 134Cs, 137Cs, 131I and 7Be.

description: An experimental demonstration of electrical detection of coherent spin motion of weakly coupled, localized electron spins in thin Fullerene C60 films at room temperature is presented. Pulsed electrically detected magnetic resonance experiments on vertical photocurrents through Al/C60/ZnO samples showed that an electron spin Rabi oscillation is reflected by transient current changes. The nature of possible microscopic mechanisms responsible for this spin to charge conversion as well as its implications for the readout of endohedral Fullerene (N@C60) spin qubits are discussed.

description: We investigate the magnetization reversal of single-domain magnetic nanoparticle driven by the circularly polarized cosine chirp microwave pulse (CCMP). The numerical findings, based on the Landau-Lifshitz-Gilbert equation, reveal that the CCMP is by itself capable of driving fast and energy-efficient magnetization reversal. The microwave field amplitude and initial frequency required by a CCMP are much smaller than that of the linear down-chirp microwave pulse. This is achieved as the frequency change of the CCMP closely matches the frequency change of the magnetization precession which leads to an efficient stimulated microwave energy absorption (emission) by (from) the magnetic particle before (after) it crosses over the energy barrier. We further find that the enhancement of easy-plane shape anisotropy significantly reduces the required microwave amplitude and the initial frequency of CCMP. We also find that there is an optimal Gilbert damping for fast magnetization reversal. These findings may provide a pathway to realize the fast and low-cost memory device.

description: We have devised and implemented a local ab initio Density Matrix Renormalization Group (DMRG) algorithm to describe multireference nondynamic correlations in large systems. For long molecules that are extended in one of their spatial dimensions, this method allows us to obtain an exact characterisation of correlation, in the given basis, with a cost that scales only quadratically with the size of the system. The reduced scaling is achieved solely through integral screening and without the construction of correlation domains. We demonstrate the scaling, convergence, and robustness of the algorithm in polyenes and hydrogen chains. We converge to exact correlation energies (with 1-10 microhartree precision) in all cases and correlate up to 100 electrons in 100 active orbitals. We further use our algorithm to obtain exact energies for the metal-insulator transition in hydrogen chains and compare and contrast our results with those from conventional quantum chemical methods.

description: We report a liquid-crystal pattern-formation experiment in which we break the lateral (translational) symmetry of a nematic medium with a laser-induced thermal gradient. The work is motivated by an improved measurement (reported here) of the temperature dependence of the electroconvection threshold voltage in planar-nematic 4-methoxybenzylidene-4-butylaniline (MBBA). In contrast with other broken-symmetry-pattern studies that report a uniform drift, we observe a strip of counterpropagating rolls that collide at a sink point, and a strong temporally periodic amplitude modulation within a width of 3-4 rolls about the sink point. The time dependence of the amplitude at a fixed position is periodic but displays a nonsinusoidal relaxation-oscillation profile. After reporting experimental results based on spacetime contours and wavenumber profiles, along with a measurement of the change in the drift frequency with applied voltage at a fixed control parameter, we propose some potential guidelines for a theoretical model based on saddle-point solutions for Eckhaus-unstable states and coupled complex Ginzburg-Landau equations.

description: Let $H(t)=(1-t/T)H_0 + (t/T)H_1$, $t\in [0,T]$, be the Hamiltonian governing an adiabatic quantum algorithm, where $H_0$ is diagonal in the Hadamard basis and $H_1$ is diagonal in the computational basis. We prove that $H_0$ and $H_1$ must each have at least two large mutually-orthogonal eigenspaces if the algorithm's running time is to be subexponential in the number of qubits. We also reproduce the optimality proof of Farhi and Gutmann's search algorithm in the context of this adiabatic scheme; because we only consider initial Hamiltonians that are diagonal in the Hadamard basis, our result is slightly stronger than the original.

description: We study whether sufficiently large integers can be written in the form cp+T_x, where p is either zero or a prime congruent to r mod d, and T_x=x(x+1)/2 is a triangular number. We also investigate whether there are infinitely many positive integers not of the form (2^ap-r)/m+T_x with p a prime and x an integer. Besides two theorems, the paper also contains several conjectures together with related analysis and numerical data. One of our conjectures states that each natural number not equal to 216 can be written in the form p+T_x with x an integer and p a prime or zero; another conjecture asserts that any odd integer n>3 can be written in the form p+x(x+1) with p a prime and x a positive integer.

description: Axion-like particles (ALPs), a class of pseudoscalars common to many extensions of the Standard Model, have the capacity to drain energy from the interiors of stars. Consequently, stellar evolution can be used to derive many constraints on ALPs. We study the influence that keV-MeV scale ALPs which interact exclusively with photons can exert on the helium-burning shells of asymptotic giant branch stars, the late-life evolutionary phase of stars with initial masses less than $8M_{\odot}$. We establish the sensitivity of the final stellar mass to such energy-loss for ALPs with masses currently permitted by stellar evolution bounds. A semi-empirical constraint on the white dwarf initial-final mass relation (IFMR) derived from observation of double white dwarf binaries is then used to exclude part of a currently unconstrained region of ALP parameter space, the cosmological triangle. The derived constraint relaxes when the ALP decay length becomes shorter than the width of the helium-burning shell. Other potential sources for stellar constraints on ALPs are also discussed.

description: Today, literature skills are necessary. Engineering and other technical professions are not an exception from this requirement. Traditionally, technical reading and writing have been framed with a limited scope, containing documentation, specifications, standards, and related text types. Nowadays, however, the scope covers also other text types, including legal, policy, and related documents. Given this motivation, this paper evaluates the readability of 201 legislations and related policy documents in the European Union (EU). The digital single market (DSM) provides the context. Five classical readability indices provide the methods; these are quantitative measures of a text's readability. The empirical results indicate that (i) generally a Ph.D. level education is required to comprehend the DSM laws and policy documents. Although (ii) the results vary across the five indices used, (iii) readability has slightly improved over time.
