description: Authors present a sea-going sailing yacht as a development environment for people taking part in sea cruises as a crew. A sailing yacht perceived as a total institution seen from the perspective of Goffman’s theory is opposed to a vision of sailing yacht as space of freedom and development environment, a place of transgression (Kozielecki) and flow (Csikszentmihalyi). Results of interviews with the crew members show that the participants of sea cruises on a sailing yacht perceive it as an friendly environment and feel its influence on self-development stimulation. The meaning of sailing yacht environment for the crew members and perception of its space and environment is discussed. Respondents claim, that during sea voyage they improved in building social relations, coping with own weaknesses, and dealing with conflicts despite of difficulties and limits they had. Struggling with the sea and experiencing the yacht environment is transgressive and developing for the crew members. The statements of the respondents allow to conclude that the environment of a seagoing yacht is friendly for them, it is a place of experiencing freedom and is conducive to the development of the individual, and thus can be an appropriate educational environment for people regardless of age.

description: Investigations of magnetically ordered phases on the femtosecond timescale have provided significant insights into the influence of charge and lattice degrees of freedom on the magnetic sub-system. However, short-range magnetic correlations occurring in the absence of long-range order, for example in spin-frustrated systems, are inaccessible to many ultrafast techniques. Here, we show how time-resolved resonant inelastic X-ray scattering (trRIXS) is capable of probing such short-ranged magnetic dynamics in a charge-transfer insulator through the detection of a Zhang-Rice singlet exciton. Utilizing trRIXS measurements at the O K-edge, and in combination with model calculations, we probe the short-range spin-correlations in the frustrated spin chain material CuGeO3 following photo-excitation, revealing a strong coupling between the local lattice and spin sub-systems.

description: Generalized Parton Distributions of the pion are evaluated in chiral quark models with the help of double distributions. As a result the polynomiality conditions are automatically satisfied. In addition, positivity constraints, proper normalization and support, sum rules, and soft pion theorems are fulfilled. We obtain explicit expressions holding at the low-energy quark-model scale, which exhibit no factorization in the t-dependence. The crucial QCD evolution of the quark-model distributions is carried out up to experimental or lattice scales. The obtained results for the Parton Distribution Function and the Parton Distribution Amplitude describe the available experimental and lattice data, confirming that the quark-model scale is low, around 320 MeV.

description: Rephasing invariants of quark and lepton mixing matrices are obtained in the standard model extended by the seesaw mechanism, and in its low-energy effective theory with the dimension-five Majorana mass operator. We classify the basic invariants, discuss non-trivial relations between them, and determine the independent invariants which characterize all the information in the mixing matrices in a basis-independent way. We also discuss the restrictions on the allowed ranges for the mixing phases, and on the rephasing invariants, which follow from a discrete invariance of the Majorana mass matrix.

The case for a second look at Canadian bank insolvency legislation
Creators: name: Ruhl, Mary Louise
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is an analysis of the bank insolvency process in Canada. The phenomenon of bank bailouts is examined and three possible rationale for bailouts are put forth. The conclusion is reached that bank bailouts can be justified on the basis of these rationale, and, therefore, that bank insolvency legislation should recognize the bailout process and provide an adequate and appropriate framework for this process. Three recent bank failures, Canadian Commercial Bank, Northland Bank and the Bank of British Columbia, are discussed, with particular emphasis on the different bailout tools used by the government in each case. These case studies are used as a framework within which to assess current Canadian bank insolvency legislation. The conclusion is reached that the legislative framework is inadequate to deal effectively with bank insolvency. By examining the American approach to bank insolvency and two recent Canadian studies on the subject, a model for reform is proposed. The model contemplates a more highly-structured legislative framework, with broad powers granted to the deposit insurer to implement a bailout in circumstances which justify this form of government intervention. Finally, this model is used as a basis on which to evaluate recent financial sector reform initiatives made by the federal government.

description: In this work, we address the problem of finding globally optimal power allocation strategies to maximize the users sum-rate (SR) as well as system energy efficiency (EE) in the downlink of single-cell multicarrier non-orthogonal multiple access (MC-NOMA) systems. Each NOMA cluster includes a set of users in which the well-known superposition coding (SC) combined with successive interference cancellation (SIC) technique is applied among them. By obtaining the closed-form expression of intra-cluster power allocation, we show that MC-NOMA can be equivalently transformed to a virtual orthogonal multiple access (OMA) system, where the effective channel gain of these virtual OMA users is obtained in closed-form. Then, the SR and EE maximization problems are solved by using very fast water-filling and Dinkelbach algorithms, respectively. The equivalent transformation of MC-NOMA to the virtual OMA system brings new theoretical insights, which are discussed throughout the paper. The extensions of our analysis to other scenarios, such as considering users rate fairness, admission control, long-term performance, and a number of future next-generation multiple access (NGMA) schemes enabling recent advanced technologies, e.g., reconfigurable intelligent surfaces are discussed. Extensive numerical results are provided to show the performance gaps between single-carrier NOMA (SC-NOMA), OMA-NOMA, and OMA.

description: Mutyzm wybiórczy jest zaburzeniem najczęściej rozwijającym się we wczesnym dzieciństwie między 3. a 5. rokiem życia, występuje również u dorosłych. Charakteryzuje się brakiem komunikacji werbalnej w niektórych sytuacjach społecznych, pomimo nawiązywania kontaktu słownego w innych sytuacjach. W artykule tym zaprezentowano przebieg rozwoju oraz obraz kliniczny mutyzmu wybiórczego dwóch sióstr od urodzenia aż do momentu rozpoznania zaburzenia. Dodatkowo wskazano, że rodzina prezentowanych pacjentek doświadczała różnych czynników stresu psychospołecznego, które można postrzegać jako czynnik stabilizujący to zaburzenie. Często to właśnie rodzina stwarza warunki sprzyjające lub hamujące jego rozwój, modeluje również wzorce relacji interpersonalnych nawiązywanych w środowisku społecznym. Zmniejszenie interakcji społecznych może wzmacniać w dziecku tendencje unikowe, tworząc nieprzystosowawczy sposób zachowania.

description: This paper proposes consistent estimators for transformation parameters in semiparametric models. The problem is to find the optimal transformation into the space of models with a predetermined regression structure like additive or multiplicative separability. We give results for the estimation of the transformation when the rest of the model is estimated non- or semi-parametrically and fulfills some consistency conditions. We propose two methods for the estimation of the transformation parameter: maximizing a profile likelihood function or minimizing the mean squared distance from independence. First the problem of identification of such models is discussed. We then state asymptotic results for a general class of nonparametric estimators. Finally, we give some particular examples of nonparametric estimators of transformed separable models. The small sample performance is studied in several simulations.

description: Dostęp do kultury osób z niepełnosprawnością stanowi ważne zagadnienie, które może determinować kierunki rozwoju działalności placówek muzealnych. Instytucje te odgrywają bowiem istotną rolę w procesie kształtowania wrażliwości poznawczej i estetycznej oraz upowszechniania wartości historii, kultury i nauki. Zadania te powinny być realizowane bez względu na stopień sprawności danej osoby zainteresowanej ich działalnością. Perspektywiczne znaczenie w tym obszarze posiadają nowoczesne technologie, które w połączeniu z rozwojem kompetencji pracowników muzeów i działaniami dostosowującymi rzeczywistą przestrzeń muzealną, mogą odgrywać fundamentalne znaczenie w procesie wyrównywania szans niepełnosprawnych odbiorów kultury. Jako nadrzędny cel artykułu należy wskazać identyfikację znaczenia beaconów w komunikacji rynkowej Muzeum Pałacu Króla Jana III w Wilanowie oraz Muzeum Książąt Czartoryskich w Krakowie z osobami posiadającymi dysfunkcję wzroku i słuchu. Na potrzeby prowadzonych rozważań postawiono tezę głoszącą, że beacony wspierają proces komunikacji rynkowej muzeów ze zwiedzającymi z niepełnosprawnością sensoryczną. W celu weryfikacji przyjętej tezy zrealizowano wywiady pogłębione w wybranych muzeach korzystających z analizowanego rozwiązania. Badania prowadzone były w latach 2019-2020. W trakcie ich realizacji podjęto próbę zidentyfikowania zakresu wykorzystania możliwości beaconów w procesie komunikacji z odbiorcami z niepełnosprawnością, jak również określenia przyczyn obecnego stanu rzeczy.

description: A generalized Ohm's law is derived to treat strongly magnetized plasmas in which the electron gyrofrequency significantly exceeds the electron plasma frequency. The frictional drag due to Coulomb collisions between electrons and ions is found to shift, producing an additional transverse resistivity term in the generalized Ohm's law that is perpendicular to both the current ($\vc{J}$) and the Hall ($\vc{J} \times \vc{B}$) direction. In the limit of very strong magnetization, the parallel resistivity is found to increase by a factor of 3/2, and the perpendicular resistivity to scale as $\ln (ω_{ce} τ_e)$, where $ω_{ce} τ_e$ is the Hall parameter. Correspondingly, the parallel conductivity coefficient is reduced by a factor of 2/3, and the perpendicular conductivity scales as $\ln(ω_{ce} τ_e)/(ω_{ce} τ_e)^2$. These results suggest that strong magnetization significantly changes the magnetohydrodynamic evolution of a plasma.

description: We study the distribution of domain areas, areas enclosed by domain boundaries (''hulls''), and perimeters for curvature-driven two-dimensional coarsening, employing a combination of exact analysis and numerical studies, for various initial conditions. We show that the number of hulls per unit area, $n_h(A,t) dA$, with enclosed area in the interval $(A,A+dA)$, is described, for a disordered initial condition, by the scaling function $n_h(A,t) = 2c_h/(A + λ_h t)^2$, where $c_h=1/8π\sqrt{3} \approx 0.023$ is a universal constant and $λ_h$ is a material parameter. For a critical initial condition, the same form is obtained, with the same $λ_h$ but with $c_h$ replaced by $c_h/2$. For the distribution of domain areas, we argue that the corresponding scaling function has, for random initial conditions, the form $n_d(A,t) = 2c_d (λ_d t)^{τ'-2}/(A + λ_d t)^{τ'}$, where $c_d=c_h + {\cal O}(c_h^2)$, $λ_d=λ_h + {\cal O}(c_h)$, and $τ' = 187/91 \approx 2.055$. For critical initial conditions, one replaces $c_d$ by $c_d/2$ (possibly with corrections of ${\cal O}(c_h^2)$) and the exponent is $τ= 379/187 \approx 2.027$. These results are extended to describe the number density of the length of hulls and domain walls surrounding connected clusters of aligned spins. These predictions are supported by extensive numerical simulations. We also study numerically the geometric properties of the boundaries and areas.

Foreigner talk in the ESL classroom : interactional adjustments to adult students at two language proficiency levels
Creators: name: Brulhart, Marilyn Mae
Publisher: name: University of British Columbia
Year: 2010

description: While native speakers adjust their speech to accommodate non-native speakers on syntactic and prosodic levels, they also make adjustments on the level of discourse. It has been argued that these interactional adjustments are crucial to the promotion of language learning. A quasi-experimental, factorial study compared the frequencies of nine interactional features used in the speech of four ESL teachers as they taught beginner and advanced level adult classes. It was expected that teachers would change their use of each feature accordingly as students neared native proficiency. Nine two-way analyses of variance were employed to capture three sources of variation in the use of the interactional features: proficiency level, teacher and proficiency level by teacher interaction. As predicted, display questions and self-repetitions were used significantly less often with advanced students than with beginners. High variability in teacher behaviour was discovered, and seemed to be primarily an artifact of lesson content. In fact, discourse usage seemed to vary as a function of lesson content, as well as proficiency level of the students. One result, the marked reduction in use of display questions at the advanced level, was discussed in light of prevailing ESL goals. As research addresses the question of whether and which adjustments do promote language acquisition, there will be implications for teacher training.

description: Artykuł prezentuje nowatorską formę prowadzenia zajęć logopedycznych z wykorzystaniem baśni dla dzieci w wieku przedszkolnym. Początki terapii przy pomocy książki sięgają starożytności. W późniejszych epokach wykorzystywano ją w niektórych szpitalach, zalecając pacjentom czytanie tekstów w celu przyspieszenia u nich procesu rekonwalescencji czy rozwoju duchowego. Celem artykułu jest udowodnienie, iż forma terapii oparta na wykorzystaniu baśni – jednego z prymarnych gatunków biblioterapii, może stać się także nieodłącznym elementem pracy logopedy. Stworzony program terapii logopedycznej zawiera trzy kluczowe elementy. Pierwszym jest logopeda, posiadający pewne cechy, predyspozycje oraz umiejętności, pozwalające na to, aby zajęcia odbywały się w jak najlepszej atmosferze, z wykorzystaniem właściwych tekstów terapeutycznych. Drugim są uczestnicy, w tym przypadku – trzyletnie dzieci. Trzecim – środki terapeutyczne, czyli baśnie, ale też bajki oraz wierszyki dla dzieci dostosowane do wieku, możliwości i zainteresowań. W programie terapeutycznym wyznaczono ogólne cele, które zrealizowano w poszczególnych scenariuszach zajęć, zaś zgromadzony materiał może służyć jako przykładowy do prowadzenia zajęć logopedycznych z dziećmi przedszkolnymi oraz być punktem wyjścia do kolejnych badań nad wykorzystaniem baśni w pracy logopedy.

Variations on Debris Disks: Icy Planet Formation at 30-150 AU for 1-3 Solar Mass Main Sequence Stars

description: We describe calculations for the formation of icy planets and debris disks at 30-150 AU around 1-3 solar mass stars. Debris disk formation coincides with the formation of planetary systems. As protoplanets grow, they stir leftover planetesimals to large velocities. A cascade of collisions then grinds the leftovers to dust, forming an observable debris disk. Stellar lifetimes and the collisional cascade limit the growth of protoplanets. The maximum radius of icy planets, roughly 1750 km, is remarkably independent of initial disk mass, stellar mass, and stellar age. These objects contain no more than 3% to 4% of the initial mass in solid material. Collisional cascades produce debris disks with maximum luminosity of roughly 0.002 times the stellar luminosity. The peak 24 micron excess varies from roughly 1% of the stellar photospheric flux for 1 solar mass stars to roughly 50 times the stellar photospheric flux for 3 solar mass stars. The peak 70-850 micron excesses are roughly 30-100 times the stellar photospheric flux. For all stars, the 24-160 micron excesses rise at stellar ages of 5-20 Myr, peak at 10-50 Myr, and then decline. The decline is roughly a power law, with f propto t^{-n} and n = 0.6-1.0. This predicted evolution agrees with published observations of A-type and solar-type stars. The observed far-IR color evolution of A-type stars also matches model predictions.

description: The paper deals with the issues of the system of education and education policy priorities in Uzbekistan. The aim of the paper is to present visible developing trends in reforming primary and secondary education in Uzbekistan within the last 30 years. The paper highlights the most significant changes that were introduced into the system of education in Uzbekistan in order to make the system more effective. Observed post-soviet strategic changes in education in Uzbekistan have had huge impact on the structure of the education system, school curricula and the educational delivery system. It is argued that changes in the system of education should include a central place for the teacher and the quality of teacher education. The paper contributes to description of education and education policy of the country that has generally been less visible in the international literature.

description: $\textbf{scqubits}$ is an open-source Python package for simulating and analyzing superconducting circuits. It provides convenient routines to obtain energy spectra of common superconducting qubits, such as the transmon, fluxonium, flux, cos(2$ϕ$) and the 0-$π$ qubit. $\textbf{scqubits}$ also features a number of options for visualizing the computed spectral data, including plots of energy levels as a function of external parameters, display of matrix elements of various operators as well as means to easily plot qubit wavefunctions. Many of these tools are not limited to single qubits, but extend to composite Hilbert spaces consisting of coupled superconducting qubits and harmonic (or weakly anharmonic) modes. The library provides an extensive suite of methods for estimating qubit coherence times due to a variety of commonly considered noise channels. While all functionality of $\textbf{scqubits}$ can be accessed programatically, the package also implements GUI-like widgets that, with a few clicks can help users both create relevant Python objects, as well as explore their properties through various plots. When applicable, the library harnesses the computing power of multiple cores via multiprocessing. $\textbf{scqubits}$ further exposes a direct interface to the Quantum Toolbox in Python (QuTiP) package, allowing the user to efficiently leverage QuTiP's proven capabilities for simulating time evolution.

The atomic density, chemical potential, critical temperature and condensate fraction, the role of the relative depth and the position of the dimple potential are analyzed by performing numerical calculations.

description: Dyskurs pedagogiczny o edukacji alternatywnej jest niezwykle szeroki, ponieważ kryzys systemu edukacji był od wieków motorem do poszukiwań nowych rozwiązań. Współczesna edukacja wiedzy i informacji stawia na innowacyjność oraz staje przed nowymi wyzwaniami. Szkoły alternatywne zaczęły powstawać, jako protest wobec szkoły tradycyjnej, a w szczególności jej cechom takim jak: autorytaryzm, uniformizm, schematyzm oraz przekazywanie uczniom gotowej wiedzy. W rezultacie tej krytyki powstały liczne szkoły alternatywne, np. „szkoły wolne”, „akademie uliczne”, „otwarte klasy”, „szkoły bez ścian”. W artykule podjęto próbę opisania historii powstania edukacji alternatywnej na Ukrainie, została wyjaśniona treść szkół alternatywnych jako zjawiska pedagogicznego, wyznaczone priorytety alternatywnych systemów pedagogicznych na przykładzie szkół autorskich oraz doświadczenie ich organizacji oraz określone ich wagi i zalety. W artykule także został zaprezentowany system nauczania zorientowanego w autorskiej szkole Mikołaja Guzika, która jest przykładem edukacji alternatywnej na Ukrainie.

description: We present simulations of coherent structures in compressible flows near the transition to turbulence using the Dissipative Particle Dynamics (DPD) method. The structures we find are remarkably consistent with experimental observations and DNS simulations of incompressible flows, despite a difference in Mach number of several orders of magnitude. The bifurcation from the laminar flow is bistable and shifts to higher Reynolds numbers when the fluid becomes more compressible. This work underlines the robustness of coherent structures in the transition to turbulence and illustrates the ability of particle-based methods to reproduce complex non-linear instabilities.

On Combining Lensing Shear Information from Multiple Filters

description: We consider the possible gain in the measurement of lensing shear from imaging data in multiple filters. Galaxy shapes may differ significantly across filters, so that the same galaxy offers multiple samples of the shear. On the other extreme, if galaxy shapes are identical in different filters, one can combine them to improve the signal-to-noise and thus increase the effective number density of faint, high redshift galaxies. We use the GOODS dataset to test these scenarios by calculating the covariance matrix of galaxy ellipticities in four visual filters (B,V,i,z). We find that galaxy shapes are highly correlated, and estimate the gain in galaxy number density by combining their shapes.

description: We present an approximate analytic expression for the photoluminescence spectral function of a model polariton system, which describes a quantum dot, with a finite number of fermionic levels, strongly interacting with the lowest photon mode of a pillar microcavity. Energy eigenvalues and wavefunctions of the electron-hole-photon system are obtained by numerically diagonalizing the Hamiltonian. Pumping and photon losses through the cavity mirrors are described with a master equation, which is solved in order to determine the stationary density matrix. The photon first-order correlation function, from which the spectral function is found, is computed with the help of the Quantum Regression Theorem. The spectral function qualitatively describes the polariton lasing regime in the model, corresponding to pumping rates two orders of magnitude lower than those needed for ordinary (photon) lasing. The second-order coherence functions for the photon and the electron-hole subsystems are computed as functions of the pumping rate.

description: The question in the title, first raised by Goldman and Donaldson, was partially answered by Reznikov. We give a complete answer, as follows: if G can be realized as both the fundamental group of a closed 3-manifold and of a compact Kähler manifold, then G must be finite, and thus belongs to the well-known list of finite subgroups of O(4).

description: Kontynuacja artykułu pt. „Efekty uczestnictwa w interpersonalnym treningu twórczego myślenia – wstępne wyniki badań predyspozycji twórczych” opublikowanego Studiach Pedagogicznych w nr 34 (2019). Artykuł dotyczy projektu pt. „Wejdź z impetem na rynek pracy. Interpersonalny trening twórczego myślenia”, uznanego za innowację społeczną. Projekt był realizowany na przełomie 2017/2018 r., a kontynuowany w roku 2019/2020 w Akademii Pedagogiki Specjalnej w Warszawie. W artykule zaprezentowano program warsztatów, efekty pracy oraz przebieg badań i wstępne wyniki. Zakładano, że uczestnictwo w Interpersonalnym Treningu Twórczego przyczyni się do zwiększenia poziomu uczestników w zakresie twórczego myślenia oraz kompetencji interpersonalnych, co może wpłynąć korzystnie na samoocenę ogólną, a w dalszej konsekwencji przełoży się na skuteczność w poszukiwaniu pracy czy „radzeniu sobie” na rynku pracy.

description: Celem przeprowadzonego w maju 2020 roku badania pilotażowego: „Kompetencje informacyjne uczniów klas IV-VIII oraz ich rodziców” była weryfikacja poprawności założonej procedury badawczej w aspekcie doboru badanych osób (rodzice i dzieci) oraz zakresu przyjętych wskaźników zmiennych (wyszczególnione kompetencje informacyjne, klasa do której uczęszcza dziecko/dzieci, jak również informacje z ‘metryczki’ respondenta (rodzica): wiek, płeć zatrudnienie, wykształcenie. Realizacja badania pilotażowego pozwoliła na udoskonalenie założeń dotyczących badania głównego. W szczególności zmiany dotyczyły konieczności wyraźniejszego rozróżnienia kompetencji informacyjnych od kompetencji informatycznych - stąd decyzja o wykorzystaniu w badaniu głównym modelu Wielkiej6 (Big6).Badanie pilotażowe uzasadniło również rozbudowę ankiety badawczej o kwestie związane ze znaczeniem kompetencji informacyjnych w procesie kształcenia się przez całe życie, konieczność określenia wiedzy respondentów na temat preferowanych sensorycznych sposobach uczenia się oraz zbadanie istotności występowania przejawów kultury pre/postfiguratywnej.

description: Accurately determining the outcome of an election is a complex task with many potential sources of error, ranging from software glitches in voting machines to procedural lapses to outright fraud. Risk-limiting audits (RLA) are statistically principled "incremental" hand counts that provide statistical assurance that reported outcomes accurately reflect the validly cast votes. We present a suite of tools for conducting RLAs using confidence sequences -- sequences of confidence sets which uniformly capture an electoral parameter of interest from the start of an audit to the point of an exhaustive recount with high probability. Adopting the SHANGRLA framework, we design nonnegative martingales which yield computationally and statistically efficient confidence sequences and RLAs for a wide variety of election types.

description: Dense retrieval, which describes the use of contextualised language models such as BERT to identify documents from a collection by leveraging approximate nearest neighbour (ANN) techniques, has been increasing in popularity. Two families of approaches have emerged, depending on whether documents and queries are represented by single or multiple embeddings. ColBERT, the exemplar of the latter, uses an ANN index and approximate scores to identify a set of candidate documents for each query embedding, which are then re-ranked using accurate document representations. In this manner, a large number of documents can be retrieved for each query, hindering the efficiency of the approach. In this work, we investigate the use of ANN scores for ranking the candidate documents, in order to decrease the number of candidate documents being fully scored. Experiments conducted on the MSMARCO passage ranking corpus demonstrate that, by cutting of the candidate set by using the approximate scores to only 200 documents, we can still obtain an effective ranking without statistically significant differences in effectiveness, and resulting in a 2x speedup in efficiency.
Effects of headings on the written recall and organization of expository text in grades 5 through 10 with emphasis on grades 7 and 8

Publisher: name: University of British Columbia

description: This study investigated the effects of headings and text organization on grade 5 through 10 students' written recall of expository prose passages written in a classification/description mode. Emphasis was placed on the results from students in grades 7 and 8. This study was a component of a three part study. The other two parallel studies emphasized grades 5 and 6 (Stables, 1985) and 9 and 10 (Gibbs, 1985). Each subject read and recalled two passages: one written at his or her grade level and one written at a low readability level. Performance on the written recalls from passages with headings and without headings was examined on the basis of the number of superordinate and subordinate ideas recalled, the superordinate and subordinate organization, and the format. Developmental trends were investigated by including the data from the two parallel studies (Gibbs, 1985; Stables, 1985). There was some evidence that headings had a significant positive effect on the number of superordinate ideas recalled from a passage of low readability. Some significant differences indicated negative effects by headings. The majority of differences, however, were not significant. Developmental trends in grades 5 through 10 were noted in the number of ideas recalled on a low readability passage and the format used on the written recalls. Implications for instruction and suggestions for further research are discussed.

description: The generalized traveling salesman problem (GTSP) is an extension of the well-known traveling salesman problem. In GTSP, we are given a partition of cities into groups and we are required to find a minimum length tour that includes exactly one city from each group. The recent studies on this subject consider different variations of a memetic algorithm approach to the GTSP. The aim of this paper is to present a new memetic algorithm for GTSP with a powerful local search procedure. The experiments show that the proposed algorithm clearly outperforms all of the known heuristics with respect to both solution quality and running time. While the other memetic algorithms were designed only for the symmetric GTSP, our algorithm can solve both symmetric and asymmetric instances.

On the Effects of Dissipative Turbulence on the Narrow Emission-Line Ratios in Seyfert Galaxies

description: We present a photoionization model study of the effects of micro-turbulence and dissipative heating on emission lines for number and column densities, elemental abundances, and ionizations typical for the narrow emission line regions (NLRs) of Seyfert galaxies. Earlier studies of NLR spectra generally found good agreement between the observations and the model predictions for most strong emission lines, such as [O III] $λ$5007, [O II] $λ$3727, [N II] $λ$6583, [Ne III] $λ$3869, and the H and He recombination lines. Nevertheless, the strengths of lines from species with ionization potentials greater than that of He$^{+}$(54.4 eV), e.g. N$^{+4}$ and Ne$^{+4}$, were often under-predicted. Among the explanations suggested for these discrepancies were (selectively) enhanced elemental abundances and contributions from shock heated gas. Interestingly, the NLR lines have widths of several 100 km s$^{-1}$, well in excess of the thermal broadening. If this is due to micro-turbulence, and the turbulence dissipates within the emission-line gas, the gas can be heated in excess of that due to photoionization. We show that the combined effects of turbulence and dissipative heating can strongly enhance N V $λ$1240 (relative to He II $λ$1640), while the heating alone can boost the strength of [Ne V] $λ$3426. We suggest that this effect is present in the NLR, particularly within $\sim$ 100 pc of the central engine. Finally, since micro-turbulence would make clouds robust against instabilities generated during acceleration, it is not likely to be a coincidence that the radially outflowing emission-line gas is turbulent.
