description: We show that the current method of determining superfluidity in optical lattices based on a visibly sharp bosonic momentum distribution $n({\bf k})$ can be misleading, for even a normal Bose gas can have a similarly sharp $n({\bf k})$. We show that superfluidity in a homogeneous system can be detected from the so-called visibility $(v)$ of $n({\bf k})$ $-$ that $v$ must be 1 within $O(N^{-2/3})$, where $N$ is the number of bosons. We also show that the T=0 visibility of trapped lattice bosons is far higher than what is obtained in some current experiments, suggesting strong temperature effects and that these states can be normal. These normal states allow one to explore the physics in the quantum critical region.

description: We present spatially resolved kinematic measurements of stellar and ionized gas components of dwarf galaxies in the stellar mass range $10^{8.5} - 10^{10} M_{\odot}$, selected from SDSS DR7 and DR8 and followed-up with Keck/LRIS spectroscopy. We study the potential effects of active galactic nuclei (AGN) on galaxy-wide gas kinematics by comparing rotation curves of 26 galaxies containing AGN, and 19 control galaxies with no optical or infrared signs of AGN. We find a strong association between AGN activity and disturbed gas kinematics in the host galaxies. While star forming galaxies in this sample tend to have orderly gas discs that co-rotate with the stars, 73\% of the AGN have disturbed gas. We find five out of 45 galaxies have gaseous components in counter-rotation with their stars, and all galaxies exhibiting counter-rotation contain AGN. Six out of seven isolated galaxies with disturbed ionized gas host AGN. At least three AGN fall clearly below the stellar-halo mass relation, which could be interpreted as evidence for ongoing star formation suppression. Taken together, these results provide new evidence supporting the ability of AGN to influence gas kinematics and suppress star formation in dwarf galaxies. This further demonstrates the importance of including AGN as a feedback mechanism in galaxy formation models in the low-mass regime.

description: This paper presents a comprehensive study on the problem of Best Arm Retention (BAR), which has recently found applications in streaming algorithms for multi-armed bandits. In the BAR problem, the goal is to retain $m$ arms with the best arm included from $n$ after some trials, in stochastic multi-armed bandit settings. We first investigate pure exploration for the BAR problem under different criteria, and then minimize the regret with specific constraints, in the context of further exploration in streaming algorithms.
 - We begin by revisiting the lower bound for the $(\varepsilon,δ)$-PAC algorithm for Best Arm Identification (BAI) and adapt the classical KL-divergence argument to derive optimal bounds for $(\varepsilon,δ)$-PAC algorithms for BAR.
 - We further study another variant of the problem, called $r$-BAR, which requires the expected gap between the best arm and the optimal arm retained is less than $r$. We prove tight sample complexity for the problem.
 - We explore the regret minimization problem for $r$-BAR and develop algorithm beyond pure exploration. We conclude with a conjecture on the optimal regret in this setting.

 Ophiomyxa pentagona (Lamarck, 1816) — Cherbonnier & Sibuet 1972: 396; Marques 1980: 103.
 Type locality: Mediterranean Sea.
 See: Tortonese (1965: 217–218, fig. 101).
 Occurrence: Northeast Atlantic and Mediterranean Sea, from Northern Spain to Senegal, including the Canaries and Cape Verde (Koehler 1906, Tortonese 1965, Madsen 1970).
 Depth: 35– 1,095 m in the Atlantic, but common in littoral-sublittoral Mediterranean waters (Tortonese 1965, Madsen 1970, Cherbonnier & Sibuet 1972).
 Habitat: hard to soft substrata, including Posidonia and Caulerpa meadows (Tortonese 1965).
 Remarks: Cherbonnier & Sibuet (1972) and Marques (1980) listed this species for the archipelago of the Azores. Though it is not entire unlikely that this species occurs in Azorean waters considering its wide distribution throughout the Northeast Atlantic, we could not trace the original report. We believe that Cherbonnier & Sibuet (1972) inclusion of the Azores in the distribution of this species was due to a mistake.

description: Vortex breaking has been traditionally studied for nonuniform critical current densities, although it may also appear due to nonuniform pinning force distributions. In this article we study the case of a high-pinning/low-pinning/high-pinning layered structure. We have developed an elastic model for describing the deformation of a vortex in these systems in the presence of a uniform transport current density $J$ for any arbitrary orientation of the transport current and the magnetic field. If $J$ is above a certain critical value, $J_c$, the vortex breaks and a finite effective resistance appears. Our model can be applied to some experimental configurations where vortex breaking naturally exists. This is the case for YBa$_2$Cu$_3$O$_{7-x}$ (YBCO) low angle grain boundaries and films on vicinal substrates, where the breaking is experienced by Abrikosov-Josephson vortices (AJV) and Josephson string vortices (SV), respectively. With our model, we have experimentally extracted some intrinsic parameters of the AJV and SV, such as the line tension $ε_l$ and compared it to existing predictions based on the vortex structure.

description: We introduce ways to measure information storage in quantum systems, using a recently introduced computation-theoretic model that accounts for measurement effects. The first, the quantum excess entropy, quantifies the shared information between a quantum process's past and its future. The second, the quantum transient information, determines the difficulty with which an observer comes to know the internal state of a quantum process through measurements. We contrast these with von Neumann entropy and quantum entropy rate and provide a closed-form expression for the latter for the class of deterministic quantum processes.

description: Σκοπός της παρούσας διπλωματικής εργασίας ήταν η ενασχόληση με τα βασικότερα θέματα που αφορούν την αεροπορική μεταφορά επιβατών. Συγκεκριμένα, στο πρώτο μέρος της εργασίας ασχοληθήκαμε με το ομοιόμορφο σύστημα ευθύνης του αεροπορικού μεταφορέα που εισάγει η διεθνής Σύμβαση του Μόντρεαλ και ο Κανονισμός (ΕΚ) 2027/1997. Παρουσιάσαμε, λοιπόν, τις τρεις περιπτώσεις ευθύνης του αερομεταφορέα, αναλύοντας, παράλληλα, τις προϋποθέσεις, οι οποίες πρέπει να συντρέχουν προκειμένου να θεωρηθεί ότι υπάρχει ευθύνη του αερομεταφορέα. Εξετάσαμε το νομικό χαρακτηρισμό της ευθύνης του αεροπορικού μεταφορέα, τα όρια της ευθύνης του αλλά και τις περιπτώσεις απαλλαγής του. Στο δεύτερο μέρος, επιχειρήσαμε μια ανάλυση του τρόπου προστασίας των δικαιωμάτων των επιβατών αεροπορικών μεταφορών εντός της Ευρωπαϊκής Ένωσης. Ειδικότερα, αναφερθήκαμε στον Κανονισμό (ΕΚ) 261/2004 και τα δικαιώματα που παρέχει στον επιβάτη σε περίπτωση ανώμαλης εξέλιξης της αεροπορικής μεταφοράς, δηλαδή σε περίπτωση άρνησης επιβίβασης, ματαίωσης και μεγάλης καθυστέρησης της πτήσης του. Το τελευταίο μέρος της εργασίας αφιερώνεται στην παρουσίαση των επερχόμενων τροποποιήσεων κυρίως του Κανονισμού (ΕΚ) 261/2004, οι οποίες έχουν καταστεί αναγκαίες ύστερα από τα κενά που έχουν δημιουργηθεί κατά την εφαρμογή του και τα οποία έχει επανειλημμένα επισημάνει με αποφάσεις του το Δικαστήριο της Ευρωπαϊκής Ένωσης.
description: The aim of this thesis was to engage with the main issues concerning the air carriage of passengers. Specifically, in the first part of this study we dealt with the uniform system of the air carrier’s liability which the international Montreal Convention and the Regulation (EC) 2027/1997 introduce. We presented the three cases of the operator’s liability, while analyzing the conditions which must be satisfied in order to assume there is responsibility of the operator. We also examined the legal characterization of the air carrier’s liability, the limits of liability and its exemptions. In the second part, we attempted an analysis of how the air passengers’ rights are protected in the European Union. In particular, we referred to the Regulation (EC) 261/2004 and the rights provided to the passenger in the event of abnormal development of air transport, ie in the event of denied boarding, cancellation and long delay of flight. The last part of this thesis is dedicated to a presentation of the upcoming amendments mainly of the Regulation (EC) 261/2004, which have become necessary after the gaps that have appeared during the application of the Regulation and which have been repeatedly pointed out by decisions of the European Court of Justice.

description: The SDSS Data Release 1 includes 1833 DA white dwarfs (WDs) and forms the largest homogeneous sample of WDs. This sample provides the best opportunity to study the statistical properties of WDs. We adopt a recently established theoretical model to calculate the mass and distance of each WD using the observational data. Then we adopt a bin-correction method to correct for selection effects and use the 1/V weight-factor method to calculate the luminosity function, the continuous mass function and the formation rate of these WDs. The SDSS DA WD sample is incomplete and suffers seriously from selection effects. After corrections for the selection effects, only 531 WDs remain. From this final sample we derive the most up-to-date luminosity function and mass function, in which we find a broad peak of WD masses centered around 0.58$M_{\odot}$. The DA WD space density is calculated as $8.81\times10^{-5}pc^{-3}$ and the formation rate is $2.579\times 10^{-13}pc^{-3}yr^{-1}$. The statistical properties of the SDSS DA WD sample are generally in good agreement with previous observational and theoretical studies, and provide us information on the formation and evolution of WDs. However, a larger and more complete all-sky WD sample is still needed to explain some subtle disagreements and unresolved issues.

 Depth: 40– 1,383 m (Harvey et al. 1988).
 Habitat: soft bottoms, sand, mud to ooze (Farran 1913).

 Remarks: Koehler (1906b) reported Ophiophrixus spinosus (as Ophiobyrsa hystricis) from off the coast of Morocco (Talisman, sta 20, 1883: 33°43’N, 9°01’46″W, 1,105 m), a species previously known from Icelandic and Scandinavian waters. Mortensen (1927a) referred to this record as between Madeira and NW Africa, which later changed to ‘off Madeira’ (Mortensen 1933a). Paterson (1985) placed the southern limit of this species not in Morocco or Madeira, but in the Azores, which is clearly a mistake, that was repeated in subsequent literature.

description: A spectrometer based on silicon nanosandwiches (SNS) is proposed for problems of personalized medicine. SNS structures exhibit properties of terahertz (THz) emitter and receiver of the THz response of biological tissue. Measurements of the current-voltage curves of the SNS structure make it possible to analyze the spectral composition of the THz response of biological tissue and determine relative contributions of various proteins and amino acids contained in the structure of DNA oligonucleotides and the corresponding compounds. Evident advantages of the proposed method are related to the fact that the THz response can be directly obtained from living biological tissue and, hence, used for express analysis of the DNA oligonucleotides. Tests of several control groups show that the further analysis of the specific features of the spectral peaks of the SNS current-voltage curves is of interest for methods of personalized diagnostics and treatment.

description: We show that many hydrodynamical properties of the BEC/BCS crossover in the presence of a Feshbach resonance at T=0 can be derived easily from the derivative expansion of the (exact) fully renormalized one-loop effective action. In particular, we calculate the velocity of sound throughout the BCS and BEC regimes and derive the generalized superfluid continuity equations for the composite two-fluid system.

Motives for the vertical integration and diversification of the Western Canadian prairie pools
Creators: name: Harris, Andrea Luise
Publisher: name: University of British Columbia
Year: 2009

description: In recent years the three Prairie Pools have actively expanded their primary operations to include a number of investments both within and outside of the agricultural sector. The Pools' investment strategies are economically interesting because they are being pursued within the context of a co-operative organizational structure which requires that the users of the cooperative business also own, control, and benefit from its operations. This thesis examines the possible economic incentives agricultural co-operatives may have to invest in vertically integrated and diversified activities using the case of the Western Canadian co-operative elevator companies as an example. The analysis undertaken in this thesis is structured in two ways. First, the economic literature regarding co-operative formation and conventional firm expansion is surveyed. This analysis suggests that an important difference between vertically integrated investments and diversified investments is that they are motivated by the realization of distincly different sets of economic benefits for the co-operative firm and its members. It is argued that co-operative vertical integration can convey benefits to members indirectly through the market, in the form of increased producer margins and improved market access. However, these benefits may not impact the "bottom line" of the co-operative firm. Diversification can, on the other hand, provide a co-operative with direct monetary benefits in the form of improved financial performance and increased profits, which can translate into increased patronage refunds available to members. The second component of this analysis involves the development of a simulation model to examine the implications of an additional hypothesis proposed to explain co-operative expansion. The proposed hypothesis is based on the notion that perhaps the indirect market benefits from cooperation and co-operative expansion are being undervalued. This undervaluation can result in a preoccupation with the monetary benefits from co-operative business, and may therefore cause a bias towards diversified investments. The model developed in this thesis illustrates that, although such a bias may improve a co-operative's rate of return, it may also result in significant opportunity costs for agricultural producers due to a decrease in a co-operative's pro-competitive effect on primary markets.

 Type locality: Mediterranean Sea.
 See: Forbes (1843: 149, pl. 14, figs. 1–7); Koehler (1921b); Mortensen (1927a).
 Occurrence: Mediterranean Sea and East Atlantic, in the Atlantic from the British Islands to the Gulf of Guinea (Mortensen 1927a, Madsen 1970), including Madeira, the Selvagens, Canaries, Cape Verde, and the Seine Seamount (Koehler 1906b, 1909, Pérez-Ruzafa et al. 2002, 2003).
 Depth: 8–185 m (Koehler 1909, Pérez-Ruzafa et al. 2002).
 Habitat: on coralligenous and detritic bottoms, among algae and sea-grass prairies or hidden in crevices (Tortonese 1965).
 Remarks: Koehler (1906b) reported material belonging to Ophiopsila aranea collected by Talisman in several stations located in the Bay of Biscay, Madeira and Cape Verde. Later, Koehler (1909) listed a specimen collected by Princesse Alice from Seine Seamount (sta 2034: 33°47’40”N, 14°21’W, 185 m). However, in the discussion of the geographical distribution of O. aranea, Koehler (1909) stated that this Mediterranean species was collected in the Azores by Talisman and taken again by Princesse Alice in the same waters. It is clear that Koehler mistook the stations’ location from both cruises, an error overlooked in subsequent literature.

 Ophiothamnus affinis Ljungman, 1872 — Nobre 1938: 75–76.
 Type locality: Portugal (38°10’N, 9°25’W).
 See: Ljungman (1872: 622); Paterson (1985: 73, fig. 27); Bartsch (1987: 125–126, figs. 25–26).
 Occurrence: North Atlantic, in west recorded from Florida and in the east from the Bay of Biscay to the Western Sahara coast (NW Africa) and Madeira (Koehler 1909, 1914 a, Bartsch 1987).
 Depth: 1,425 –1,935 m (Paterson 1985), though in the West Atlantic it was recorded at depths of 229–491 m (Koehler 1914a).
 Habitat: soft sediment (sand; Koehler 1914a).
 Remarks: Nobre (1938) listed a specimen of Ophiothamnus affinis collected by Talisman and Travailleur between the Azores and Portugal continental shores, at 38°23’N, 31°10’W (probably using the Paris Meridian) and at a depth of 500 m without referring to a specific station. The coordinates given by the author seem to refer to station 123 conducted by Talisman in 1883, placing the specimen well inside the Azorean waters. However, Koehler (1906b) did not report any material of O. affinis or Ophioleda minima (as Nobre already acknowledged these species to be conspecific) from that particular station. Furthermore, Koehler (1906a, 1906b, 1914a) described Ophioleda minima on the basis of specimens collected by Travailleur and Talisman in Northern Spanish waters at a depth of 1,037 –1,350 m, not between the Azores and Portugal as Nobre seemed to claim. In spite of the wide distribution of O. affinis in the North Atlantic, the presence of this species in the archipelago is still to be confirmed.

With the rising trend in antibiotic resistance, there is a pressing clinical need for new antimicrobial chemistries and biomaterial design approaches enabling on-demand activation of antibiotic-free antimicrobial functionality following an infection that are environment-friendly, flexible and commercially-viable. This study explores the feasibility of integrating a bioresorbable electrospun polymer scaffold with localised antimicrobial photodynamic therapy (aPDT) capability. To enable aPDT, we encapsulated a photosensitiser (PS) in polyester fibres in the PS inert state, so that the antibacterial function would be activated on-demand via a visible light source. Fibrous scaffolds were successfully electrospun from FDA-approved polyesters, either poly(epsilon-caprolactone (PCL) or poly[(rac-lactide)-co-glycolide] (PLGA) with encapsulated PS (either methylene blue (MB) or erythrosin B (ER)). The electrospun fibres achieved an ~100 wt.% loading efficiency of PS, which significantly increased their tensile modulus and reduced their average fibre diameter and pore size with respect to PS-free controls. In vitro, PS release varied between a burst release profile to limited release within 100 hours depending on the selected scaffold formulation. Exposure of PS-encapsulated PCL fibres to visible light successfully led to at least a 1 log reduction in E. coli viability after 60 minutes of light exposure whereas PS-free electrospun controls did not inactive microbes. This study successfully demonstrates the significant potential of PS-encapsulated electrospun fibres as photodynamically active biomaterial for antibiotic-free infection control.

description: A model for a flat isotropic universe with a negative cosmological constant $Λ$ and a massless scalar field as sole matter content is studied within the framework of Loop Quantum Cosmology. By application of the methods introduced for the model with $Λ=0$, the physical Hilbert space and the set of Dirac observables are constructed. As in that case, the scalar field plays here the role of an emergent time. The properties of the system are found to be similar to those of the $k=1$ FRW model: for small energy densities, the quantum dynamics reproduces the classical one, whereas, due to modifications at near-Planckian densities, the big bang and big crunch singularities are replaced by a quantum bounce connecting deterministically the large semiclassical epochs. Thus in Loop Quantum Cosmology the evolution is qualitatively cyclic.

The Finite Neuron Method and Convergence Analysis

description: We study a family of $H^m$-conforming piecewise polynomials based on artificial neural network, named as the finite neuron method (FNM), for numerical solution of $2m$-th order partial differential equations in $\mathbb{R}^d$ for any $m,d \geq 1$ and then provide convergence analysis for this method. Given a general domain $Ω\subset\mathbb R^d$ and a partition $\mathcal T_h$ of $Ω$, it is still an open problem in general how to construct conforming finite element subspace of $H^m(Ω)$ that have adequate approximation properties. By using techniques from artificial neural networks, we construct a family of $H^m$-conforming set of functions consisting of piecewise polynomials of degree $k$ for any $k\ge m$ and we further obtain the error estimate when they are applied to solve elliptic boundary value problem of any order in any dimension. For example, the following error estimates between the exact solution $u$ and finite neuron approximation $u_N$ are obtained. $$ \|u-u_N\|_{H^m(Ω)}=\mathcal O(N^{-{1\over 2}-{1\over d}}). $$ Discussions will also be given on the difference and relationship between the finite neuron method and finite element methods (FEM). For example, for finite neuron method, the underlying finite element grids are not given a priori and the discrete solution can only be obtained by solving a non-linear and non-convex optimization problem. Despite of many desirable theoretical properties of the finite neuron method analyzed in the paper, its practical value is a subject of further investigation since the aforementioned underlying non-linear and non-convex optimization problem can be expensive and challenging to solve. For completeness and also convenience to readers, some basic known results and their proofs are also included in this manuscript.

 Ophiothrix cotteaui (de Loriol, 1900) — Madsen 1970: 215–216, figs. 36a–b.
 Type locality: Liberia.
 See: Madsen (1970).
 Occurrence: East Atlantic, from Portugal and the Gulf of Cadiz to Angola (Koehler 1906b, 1914b, Cadenat 1938, Marques 1980), including Madeira (Koehler 1906b).
 Depth: c. 0–820 m (Madsen 1970, Marques 1980).
 Habitat: soft sediments, on the branches of gorgonian corals (Cadenat 1938, Madsen 1970).
 Remarks: Koehler (1906a, b) described a new species, Ophiothrix indigna, based on material collected by Talisman from the Gulf of Cadiz (sta 36, 1882: 35°35’00”N, 6°21’46”W, c. 150 m) and Madeira waters (sta 55, 1882: 32°41’20”N, 16°37’46”W, 370 m). In a review of the West African ophiuroids, Madsen (1970) concluded that O. indigna should be considered a junior synonymy of O. cotteaui as it merely represented adults of the later. However, by a lapse Madsen placed O. indigna ’s type locality in the Azores.

description: We derive the the effective lagrangian that describes the interactions among vector, axial-vector mesons and pseudoscalars starting from the extended chiral quark model (ECQM). The results for the low-energy constants of this effective lagrangian have a parametric resemblance with existing predictions based on the Nambu-Jona-Lasinio model (except for some overall signs that we correct), but are numerically different. Therefore a precise measurement of these decay constants can shed some light on the way chiral symmetry breaking is modelled in QCD. Although most of the constants are poorly measured, comparison with phenomenology allows us to determine one of the parameters of the ECQM that could not be fully determined in previous analyses.

We believe some aspects of the recent article by Eady et al. (Citation2024) recently published in the New Zealand (NZ) Journal of Agricultural Research require comment to address several flaws and omissions in their assessments of nitrogen (N) leaching and associated commentary. These relate specifically to material presented on pages 8–10 of the article in the section entitled ‘Leaching from pasture'.

description: We have studied the $γp\to ηϕp$ reaction within the effective Lagrangian approach, and our results show that there may be a peak, at least a bump structure around 2180 MeV associated to the resonance $ϕ(2170)$ in the $ηϕ$ mass distribution. We suggest to search for the resonance $ϕ(2170)$ in this reaction, which would be helpful to shed light on its nature.

description: We present a statistical analysis of the photometric properties and spatial distribution of more than 2,800 MgII absorbers with 0.370.8Ådetected in SDSS quasar spectra. Using an improved image stacking technique, we measure the cross-correlation between MgII gas and light (in the g, r, i and z-bands) from 10 to 200 kpc and infer the light-weighted impact parameter distribution of MgII absorbers. Such a quantity is well described by a power-law with an index that strongly depends on W_0, ranging from ~-1 for W_0~ 1.5Å. At redshift 0.37

description: Σκοπός της παρούσας διπλωματικής εργασίας ήταν η βελτιστοποίηση των Γνωστικών Συστημάτων Ραδιοεπικοινωνιών (Cognitive Radio systems) χρησιμοποιώντας τον αλγόριθμο ΒΒΟ (Biogeography-Based Optimization) και τους αλγορίθμους RCBBO (Real-Coded Biogeography-Based Optimization). Οι εν λόγω αλγόριθμοι αξιολογήθηκαν και συγκρίθηκαν μεταξύ τους με βάση τα αποτελέσματα που προέκυψαν από τις προσομοιώσεις τους με την βοήθεια του MATLAB. Η εργασία μας χωρίζεται σε πέντε επιμέρους κεφάλαια. Στο πρώτο και στο δεύτερο κεφάλαιο γνωρίσαμε τα Γνωστικά Συστήματα Ραδιοεπικοινωνιών και δώσαμε μια αναλυτική περιγραφή των παραμέτρων λειτουργίας τους και των αντίστοιχων κριτηρίων επίδοσης. Στο τρίτο κεφάλαιο, περιγράψαμε αναλυτικά τον αλγόριθμο ΒΒΟ και τους αλγορίθμους RCBBO που ανήκουν στους εξελικτικούς αλγορίθμους και βασίζονται στην επιστήμη της Βιογεωγραφίας. Στο τέταρτο κεφάλαιο προσπαθήσαμε να περιγράψουμε με μαθηματικό τρόπο το πρόβλημα προς βελτιστοποίηση ορίζοντας τις ολικές συναρτήσεις καταλληλότητας πολλαπλών κριτηρίων τις οποίες χρησιμοποιήσαμε στις προσομοιώσεις των αλγορίθμων μας. Στο πέμπτο κεφάλαιο παρουσιάσαμε τα αποτελέσματα από τις προσομοιώσεις των αλγορίθμων, με την παράθεση πινάκων και γραφικών παραστάσεων. Τέλος, με βάση τα αποτελέσματα αυτά, αξιολογήθηκαν και συγκρίθηκαν οι επιδόσεις των αλγορίθμων μας και τελικά προέκυψε το συμπέρασμα ότι οι αλγόριθμοι RCBBO παρουσιάζουν καλύτερα αποτελέσματα από τον αλγόριθμο ΒΒΟ για το πρόβλημα της βελτιστοποίησης των Γνωστικών Συστημάτων Ραδιοεπικοινωνιών.
description: The aim of the present thesis was the optimization of a Cognitive Radio System using the BBO (Biogeography-Based Optimization) algorithm and the RCBBO (Real-Coded Biogeography-Based Optimization) algorithms. These algorithms are evaluated and compared with each other based on the results which have been obtained by their simulations using MATLAB. This thesis is divided into five chapters. In the first and the second chapter, we presented the Cognitive Radio Systems and we gave a detailed description of their operating parameters and the respective performance objectives. In the third chapter, we analyzed BBO algorithm and RCBBO algorithms which belong to the evolutionary algorithms and are based on the science of Biogeography. In the fourth chapter, we have described the optimization problem, defining the respective fitness functions which are used in the simulations of our algorithms. In the fifth chapter, we presented the simulation results, using tables and graphs. Based on these results, we evaluated and compared the performance of our algorithms, and finally we came to the conclusion that RCBBO algorithms can obtain better performance than BBO algorithm for the optimization of Cognitive Radio Systems.

description: Synthetic spectra generated with the parameterized supernova synthetic-spectrum code SYNOW are compared to spectra of the unusual Type Ib supernova 2005bf. We confirm the discovery by Folatelli et al. (2006) that very early spectra (about 30 days before maximum light) contain both photospheric-velocity (8000 km/s) features of He I, Ca II, and Fe II, and detached high-velocity (14,000 km/s) features of H-alpha, Ca II, and Fe II. An early spectrum of SN 2005bf is an almost perfect match to a near-maximum-light spectrum of the Type Ib SN 1999ex. Although these two spectra were at very different times with respect to maximum light (20 days before maximum for SN 2005bf and five days after for SN 1999ex), they were for similar times after explosion - about 20 days for SN 2005bf and 24 days for SN 1999ex. The almost perfect match clinches the previously suggested identification of H-alpha in SN 1999ex and supports the proposition that many if not all Type Ib supernovae eject a small amount of hydrogen. The earliest available spectrum of SN 2005bf resembles a near-maximum-light spectrum of the Type Ic SN 1994I. These two spectra also were at different times with respect to maximum light (32 days before maximum for SN 2005bf and four days before for SN 1994I) but at similar times after explosion - about eight days for SN 2005bf and 10 days for SN 1994I. The resemblance motivates us to consider a reinterpretation of the spectra of Type Ic supernovae, involving coexisting photospheric-velocity and high-velocity features. The implications of our results for the geometry of the SN 2005bf ejecta, which has been suggested to be grossly asymmetric, are briefly discussed.

description: We present a variety of new results on finite sets A of integers for which the sumset A+A is larger than the difference set A-A, so-called MSTD (more sums than differences) sets. First we show that there is, up to affine transformation, a unique MSTD subset of {\bf Z} of size 8. Secondly, starting from some examples of size 9, we present several new constructions of infinite families of MSTD sets. Thirdly we show that for every fixed ordered pair of non-negative integers (j,k), as n -> \infty a positive proportion of the subsets of {0,1,2,...,n} satisfy |A+A| = (2n+1) - j, |A-A| = (2n+1) - 2k.

description: Erroneous— Astropecten bispinosus (Otto, 1823)   Reports for the Azores:
 Astropecten bispinosus (Otto, 1823) — Ludwig 1897: 16–31, pl. 2, fig. 6, pl. 6, fig. 6; Koehler 1921b: 46–47, fig. 33, 1924: 191–192; Mortensen 1927a: 56; Parenzan 1934: 211–216, fig. 7; Nobre 1938: 51–52, figs. 23, 24; Madsen 1950: 181–182; Tortonese 1965: 140–141, fig. 62; Micael & Costa 2010: 322; Micael et al. 2012: 5.
 Type locality: Mediterranean Sea.
 See: Koehler (1921b); Tortonese (1965).
 Occurrence: Mediterranean Sea, reported elsewhere in the Portuguese continental shores (Northeast Atlantic; Koehler 1921 a, Nobre 1938).
 Depth: shallow waters (Koehler 1921a).
 Habitat: sandy bottoms and Zostera prairies (Koehler 1921a).
 Remarks: the first report of Astropecten bispinosus in the Azores appears in Ludwig (1897). This author believed that A. platyacanthus was just a variation of A. bispinosus, and in his review of the Mediterranean sea stars, listed Barrois (1888) ’s record in the synonymy list of later species. This caused subsequent authors, such as Koehler (1921b), to include the Azores in this species geographical range without acknowledging the synonymy or the reexamination of Barrois (1888) ’s material. The debate whether A. platyacanthus is a variety of A. bispinosus seems to have ended with the publication of Zulliger & Lessios (2010) as they are now considered as two valid species (Mah 2017). Nevertheless, A.M. Clark & Downey (1992) considered both species to be endemic to the Mediterranean waters, believing that all the reports from the Atlantic were based on misidentifications or doubtful locality data. The lack of documented material from the Azorean waters appears to support these authors, and thus we consider the Azorean reports as erroneous.

Viscosity and boost invariance at RHIC and LHC

description: We consider the longitudinal hydrodynamic evolution of the fireball created in a relativistic heavy-ion collision. Nonzero shear viscosity reduces the colling rate of the system and hinders the acceleration of the longitudinal flow. As a consequence, the initial energy density needed to reproduce the experimental data at RHIC energies is significantly reduced. At LHC energies, we expect that shear viscosity helps to conserve a Bjorken plateau in the rapidity distributions during the expansion.
