description: The purpose of this paper is to formulate and solve a H-infinity controller synthesis problem for a class of non-commutative linear stochastic systems which includes many examples of interest in quantum technology. The paper includes results on the class of such systems for which the quantum commutation relations are preserved (such a requirement must be satisfied in a physical quantum system). A quantum version of standard (classical) dissipativity results are presented and from this a quantum version of the Strict Bounded Real Lemma is derived. This enables a quantum version of the two Riccati solution to the H-infinity control problem to be presented. This result leads to controllers which may be realized using purely quantum, purely classical or a mixture of quantum and classical elements. This issue of physical realizability of the controller is examined in detail, and necessary and sufficient conditions are given. Our results are constructive in the sense that we provide explicit formulas for the Hamiltonian function and coupling operator corresponding to the controller.

Assessing competition using absolute and relative growth rates and relative density of wood for red pine (Pinus resinosa Ait.)
Creators: name: LaRocque, G.
Publisher: name: University of British Columbia
Year: 2011

description: Effects of competition among trees of red pine (Pinus resinosa Ait.) on tree growth and on the relative density of wood were examined. Data came from a spacing trial with initial spacings ranging from 1.2x1.2 m to 6.0x6.0 m; individual trees were measured for DBH, height, and crown dimensions at several ages. The first objective was to evaluate if relative growth rate (RGR) expressed the competitive status of stands better than absolute growth rate (AGR), which is normally used in forestry. Relative growth rate was found to be superior to AGR. While AGR was always positively related to tree size, RGR decreased with tree size before the onset of competition or when it was not too severe, and increased with tree size under severe competitive stress. This implies that small trees were more efficient than large trees at producing new biomass before the onset of competition. The effect of competition was to reduce the efficiency of small trees compared to large ones. The second objective was to examine whether different measures of crown efficiency rarely used in forestry were related to the competitive status of stands. The ratios of crown width to crown length, and of crown length to DBH, the ratio of AGR in DBH to crown width and to crown length, and the ratio of AGR in basal area to foliage biomass showed a pattern similar to RGR: a decrease with tree size before the onset of competition, and an increase with tree size after. Crown ratio showed little variation with tree size for a particular spacing until the onset of competition, and increased with tree size afterwards. The third objective consisted of examining whether the relative density of wood in red pine was affected by different initial spacings. Increment cores were sampled at breast height on 30 trees within every spacing and scanned on a direct reading X-ray densitometer to determine the relative density of the wood. Ring width, the relative density of the ring, earlywood and late-wood densities, minimum and maximum densities, and proportions of earlywood and latewood were analysed. The relative density of the rings and of the latewood zones and the proportions of early-wood and latewood were closely associated with the change in competitive status of stands. Furthermore, the changes in wood density were closely associated with the changes in crown ratio. RGR and measures of crown efficiency describe the competitive status of stands better than classical measures of growth. Their use for evaluating the response of stands under intensive management still remains to be investigated.

description: Η μελέτη πραγματεύεται τα κλινικά αρθροσκοπικά και ιστομορφολογικά χαρακτηριστικά της δισκοειδούς δυσμορφίας του μηνίσκου. Κατά την κλινική μελέτη δεν αποδείχθηκε στατιστικά σημαντικά προγνωστικά άξια των κλινικών σημείων που έχουν περιγραφεί ως κλάσμα κλισικά κλινικά χαρακτηριστικά της πάθησης στην παιδική ηλικία σε ενήλικες ασθενείς. Η κλινική έκβαση της μερικής εκτομής ακέραιου δισκοειδούς έξω μηνίσκου υπερέχει στατιστικά σαφώς εκείνου των περιπτώσεων δισκοειδούς μηνίσκου με ρήξη. Η συχνότητα ρήξης του δισκοειδούς μηνίσκου σχετίζεται με την ηλικία του ασθενούς, αφού σε ασθενείς ηλικίας μικρότερης των 35 ετών η συχνότητα ρήξης σχεδόν διπλασιάζεται. Δεν παρατηρήθηκε στατιστικά σημαντική συσχέτιση μεταξύ του τύπου δισκοειδούς δυσμορφίας και του είδους της ρήξης ή συνοδού ενδαρθρικής βλάβης. Η αρχιτεκτονική του δικτύου των ακτινωτών ινών κολλαγόνου δεν διαφέρει σημαντικά μεταξύ δισκοειδούς και φυσιολογικού έξω μηνίσκου. Αντίθετα, στο δισκοειδή μηνίσκο παρατηρήθηκε σημαντική αποδιοργάνωση του δικτύου των κυκλότερων ινών κολλαγόνου, στοιχείο που, πιθανώς, εμπλέκεται στην αιτιοπαθογένεση της αυξημένης συχνότητας ρήξης των μηνίσκων με δισκοειδή δυσμορφία
description: The present study investigated the clinical arthroscopic and histomorphological features of the meniscus discoid variation. With regard to the results of the clinical study no statisticaly significant predictine value of the physical signs wich have been accepted as diagnostic in children was recorded in adult patients. The clinical out come of partial resection of intact discoid lateral meniscus was far superior in comparison with torn discoid meniscus cases. The incidence of discoid meniscus tear apreared correlation with patient age while it reached almost double value in the patients older than 35 years old. No correlation of statistical significance was found between tear pattern or cowcomittant intraarticular lesion and type of discoid meniscus. Regarding with the architecture of the radial collagen system no significant difference was observed. On the other hand statistically significant disorganization of the circularly oriented collagen fibrils in the discoid meniscus specimens was found

description: In this paper we argue that our comprehension of musical participation—the complex network of interactive dynamics involved in collaborative musical experience—can benefit from an analysis inspired by the existing frameworks of dynamical systems theory and coordination dynamics. These approaches can offer novel theoretical tools to help music researchers describe a number of central aspects of joint musical experience in greater detail, such as prediction, adaptivity, social cohesion, reciprocity, and reward. While most musicians involved in collective forms of musicking already have some familiarity with these terms and their associated experiences, we currently lack an analytical vocabulary to approach them in a more targeted way. To fill this gap, we adopt insights from these frameworks to suggest that musical participation may be advantageously characterized as an open, non-equilibrium, dynamical system. In particular, we suggest that research informed by dynamical systems theory might stimulate new interdisciplinary scholarship at the crossroads of musicology, psychology, philosophy, and cognitive (neuro)science, pointing toward new understandings of the core features of musical participation.

description: A straight cylindrical duct is considered containing an axial mean flow that is uniform everywhere except within a boundary layer near the wall, which need not be thin. Within this boundary layer the mean flow varies parabolically. The linearized Euler equations are Fourier transformed to give the Pridmore-Brown equation, for which the Greens function is constructed using Frobenius series. Inverting the spatial Fourier transform, the critical layer contribution is given as the non-modal contribution from integrating around the continuous spectrum branch cut. This contribution is found to be the dominant downstream contribution to the pressure perturbation in certain cases, particularly for thicker boundary layers. The continuous spectrum branch cut is also found to stabilize what are otherwise convectively unstable modes by hiding them behind the branch cut. Overall, the contribution from the critical layer is found to give a neutrally stable non-modal wave with a phase velocity equal to the mean flow velocity at the source when the source is located within the sheared-flow region, and to decay algebraically along the duct as $O(x^{-5/2})$ for a source located with the uniform flow region. The Frobenius expansion, in addition to being numerically accurate close to the critical layer where other numerical methods loose accuracy, is also able to locate modal poles hidden behind the branch cut, which other methods are unable to find; this includes the stabilized hydrodynamic instability. Matlab code is provided to compute the Greens function.

description: The Unruh effect is the prediction that particle detectors accelerated through the vacuum get excited by the apparent presence of radiation quanta -- a fundamental quantum phenomenon in the presence of acceleration. Prior treatments of the Unruh effect, that presume a classically prescribed trajectory, do not account for the quantum dynamics of the detector's center-of-mass. Here, we study more realistic detectors whose center of mass is a quantized degree of freedom being accelerated by an external classical field. We investigate the detector's recoil due to the emission of Unruh quanta. Vice versa, we also study the recoil's impact on the emission of Unruh quanta and the excitation of the detector. We find that the recoil due to the emission of Unruh quanta may be a relevant experimental signature of the Unruh effect.

description: We present the spectroscopic analysis of 333 OB-type stars extracted from VLT-MUSE observations of the central 30 x 30 pc of NGC 2070 in the Tarantula Nebula on the Large Magellanic Cloud, the majority of which are analysed for the the first time. The distribution of stars in the spectroscopic Hertzsprung-Russell diagram (sHRD) shows 281 stars in the main sequence. We find two groups in the main sequence, with estimated ages of 2.1$\pm$0.8 and 6.2$\pm$2 Myr. A subgroup of 52 stars is apparently beyond the main sequence phase, which we consider to be due to emission-type objects and/or significant nebular contamination affecting the analysis. As in previous studies, stellar masses derived from the sHRD are systematically larger than those obtained from the conventional HRD, with the differences being largest for the most massive stars. Additionally, we do not find any trend between the estimated projected rotational velocity and evolution in the sHRD. The projected rotational velocity distribution presents a tail of fast rotators that resembles findings in the wider population of 30 Doradus. We use published spectral types to calibrate the HeI$λ$4921/HeII$λ$5411 equivalent-width ratio as a classification diagnostic for early-type main sequence stars when the classical blue-visible region is not observed. Our model-atmosphere analyses demonstrate that the resulting calibration is well correlated with effective temperature.

description: For every conserved quantity written as a sum of local terms, there exists a corresponding current operator that satisfies the continuity equation. The expectation values of current operators at equilibrium define the persistent currents that characterize spontaneous flows in the system. In this work, we consider quantum many-body systems on a finite one-dimensional lattice and discuss the scaling of the persistent currents as a function of the system size. We show that, when the conserved quantities are given as the Noether charges associated with internal symmetries or the Hamiltonian itself, the corresponding persistent currents can be bounded by a correlation function of two operators at a distance proportional to the system size, implying that they decay at least algebraically as the system size increases. In contrast, the persistent currents of accidentally conserved quantities can be nonzero even in the thermodynamic limit and even in the presence of the time-reversal symmetry. We discuss `the current of energy current' in $S=1/2$ XXZ spin chain as an example and obtain an analytic expression of the persistent current.

description: Aims of the study were the investigation of a) gender roles at the assignment of household work and working outdoors, b) attitudes and beliefs about work (household work and outdoor work) and c) the connection of work to school image (performance, future academic plans and study organization) and personal functioning factors of male and female adolescent students. In the study participated 464 students, 188 boys and 276 girls, attending third class of Gymnasium and second class of Lyceum, from 13 schools located at urban, semi urban and rural regions. A combination of quantitative methods was used for data collection. Findings indicate that a) household work and outdoor work is assigned according to sex stereotypes, b) boys hold more traditional ideas compared to girls, regarding the assignment of household work, c) adolescents who participate in household work, compared to those who work outdoors, have less negative consequences on their school image and more positive consequences on their personality. The attitudes of both sexes towards household work and outdoor work, under the excess burden of school demands and changes in the family structure, are discussed, as well as the role that school can play to promote equal gender roles

description: Ad oltre un decennio dalla riforma costituzionale del 2001, la non compiuta attuazione della stessa sembra condurre ad una nuova ed assai prossima revisione costituzionale.
Nel mutato quadro costituzionale di quest’ultimo periodo l’attenzione e l’interesse sono stati richiamati da una grande quantità di accordi, di intese e di altri moduli consensuali, introdotti ed esitati nei rapporti tra Stato ed autonomie territoriali.
Dall’esame del sistema delle Conferenze si è evidenziata la loro indispensabilità ai fini del coordinamento delle azioni politico –amministrative delle autonomie territoriali, ma è anche venuta fuori l’esigenza di ricorrere frequentemente ad altri tipi di moduli consensuali, spesso non tipizzati in ambito legislativo.
I principi di sussidiarietà e di leale collaborazione inducono non di rado ad assumere, nella concretezza, forme eterogenee poco chiare e confuse (accordo, intesa, concerto, parere) che, pur considerati i contributi offerti dalla dottrina e dalla giurisprudenza, richiederebbero un intervento da parte del legislatore.
L’approfondimento tematico ha rilevato, nel contesto di rapporti tra Stato ed autonomie territoriali, un movimento per così dire ondulatorio tra accese spinte autonomistiche e rimarcate esigenze centralistiche, lasciando ancora nella prospettiva una operativa ed efficiente armonia istituzionale.
description: More than one decade after the lack of implementation of the 2001constitutional reform  leads to a forthcoming constitutional review.
Recently, due to undergoing changes of the constitutional framework, the State and local authorities have focused their attention on establishing a large number of mutual agreements, arrangements and further consensual paradigms.
The system of Conferences undertook an examination which emphasizes their essential role to coordinate both the political and administrative actions of local authorities, as well as necessity of further consensual paradigms rarely taken into account by the legislative field.
The principles of subsidiarity and fairness often lead to unclear and confusing heterogeneous forms of agreements.  although they are considered contributions of legal authors and jurisprudence, the intervention of the legislator should be required.
Having regard to the relation between the State and the local autonomies, the analysis revealed an ambiguous trend between autonomist and centralist positions. 
In conclusion, in order to achieve significant and rapid changes in the second part of the Constitution, the aim is rationalization and simplification of the functions and procedures, which leads to time, energy and resources efficiency.

description: Translation Studies is considered to be a relatively new area of expertise. What critics seem to agree upon is the communicative nature of translation. In this light, this work‟s major aim has been to illustrate issues regarding the Greek translations of Angela Carter‟s translated novels. During the process of the re-creation of a text in a target language, the translator holds a major role as the mediator between the source and target language cultures. The result of his/her decision-making defines the identity of the translated text within the target language literature. With regard to literary translation, complex issues arise which need to be studied in their immediate and wider contexts. These issues will be examined from a translatological point of view by focusing on the manipulation of the source texts in the target language, in order to illuminate areas of interest in the translations under study in relation to the prominent aspects of the source texts they derived from

description: Reflection is an often addressed design goal in Human-Computer Interaction (HCI) research. An increasing number of artefacts for reflection have been developed in recent years. However, evaluating if and how an interactive technology helps a user reflect is still complex. This makes it difficult to compare artefacts (or prototypes) for reflection, impeding future design efforts. To address this issue, we developed the \emph{Technology-Supported Reflection Inventory} (TSRI), which is a scale that evaluates how effectively a system supports reflection. We first created a list of possible scale items based on past work in defining reflection. The items were then reviewed by experts. Next, we performed exploratory factor analysis to reduce the scale to its final length of nine items. Subsequently, we confirmed test-retest validity of our instrument, as well as its construct validity. The TSRI enables researchers and practitioners to compare prototypes designed to support reflection.

description: Congress will soon consider new legislation to replace the expiring Food Security Act of 1985. The U.S. Department of Agriculture and many groups around the country are studying the effects of the 1985 law and other legislation to see what lessons can be applied in the 1990's. This bulletin describes current domestic food assistance programs, their relationships to each other, their effects, their impact on the food production and marketing sectors, and their cost. It then looks at options for food assistance policy in the next decade under a new farm law. It is worth noting that the new farm law will not cover the child nutrition programs or the Special Supplemental Food Program for Women, Infants, and Children (WIC). However, these programs are still discussed in this bulletin.
English as a second language teachers' attention to student characteristics during lesson planning : a novice-expert study
Creators: name: MacLeod, Cheri Dawn
Publisher: name: University of British Columbia
Year: 2011

description: Recent changes in language teaching methodology have created needs for a better understanding of lesson planning among English as a second language (ESL) teachers . Research on teacher thinking and lesson planning in general suggests that teachers mainly pay attention to content, activities, and student characteristics, but these elements may have unique features in second language instruction. The present study investigated the lesson planning of 6 inexperienced student teachers of ESL and 6 experienced sponsor teachers of ESL teaching the same students in a practicum context. The teachers' planning was analyzed in terms of the attention they gave to content, activities, and student characteristics, while assessing possible differences between the two groups. The study found that ESL teachers gave more consideration to content and activities than they did to student characteristics. Both groups considered these three aspects of lesson planning individually about half the time and in conjunction with other aspects of planning about half the time. Experienced teachers proved to use more complex mental representations of lesson planning than student teachers did. However, many individual differences emerged among the inexperienced and experienced teachers, obscuring differences between groups for most of the planning behaviors assessed. The student characteristics most often mentioned in think-aloud protocols during lesson planning, and reported as most important on a rating scale, were students' English proficiency, personal motivation, language learning needs, and interests. Further studies should use a larger sample of teachers and might profitably investigate lesson planning throughout an entire course.

description: Σκοπός της παρούσας μελέτης ήταν η καταγραφή αντιλήψεων ιατρών και ασθενών για το ανθρωποκεντρικό πρότυπο φραντίδας. Επιπλέον, αναζητήθηκε πιθανή μεταβολή των αντιλήψεων φοιτητών ιατρικής από την επίδραση του προγράμαμτος σπουδών. Πληθυσμός-Μέθοδος. 400 ιατροί (ποσοστό ανταπόκρισης 79.8%) και 454 ασθενείς(59,6%) κλήθηκαν να απαντήσουν σε δημογραφιξκές ερωτήσεις και ερωματολόγια για τη σχέση ιατρού0-ασθενή. Οι φοιτητές ιατρικής μελετήθηκαν στο 4ο έτος και 2 χρόνια μετά(στο 6ο). Αποτελέσματα. Οι προσδοκίες των ασθενών για πληροφόρηση ήταν ιδιαίτερα υψηλές, αλλά δεν ακολουθούνταν από αντίστοιχα υψηλή επιθυμία για εμπλοκή στη λήψη αποφάσεων. Οι ιατροί βρέθηκαν λιγότερο πρόθυμοι να ενημερώσουν και να ενεργοποιήσουν τη συμμετοχή των ασθενών τους. Η προηγούμενη εκπαίδευση σε θέματα επικοινωνίας βρέθηκε να επηρεάζει σημαντικά τις αντιλήψεις. Τέλος, οι αντιλήψεις των φοιτητών βρέθηκαν σημαντικά ιατροκεντρικότερες στο 6ο έτος. Συμπεράσματα. Η εκπαίδευση σε δεξιότητες επικοινωνίας φαίνεται να αποτελεί το ζητούμενο μέσο για την τροποποίηση αντιλήψεων, με απώτερο σκοπό τη δημιουργία ιατρών ικανών να παρέχουν ιατρική φροντίδα ανταποκρινόμενη στις ανάγκες του έλληνα ασθενή
description: Purpose : to investigate attitudes towards patient-centred care in patients and doctors. Moreover, this longitudinal study aimed to assess possible changes in attitudes in medical students, as they progressed through the clinical curriculum. Material-Method 400 physicians(response rate 79,8%) answered to demographic questions and tools on doctor-patient relationship. The students were tested on two occasions : during year 4 and often 2 years at the end of the clerkship. Results : patients' expectations for information were very high, but they weren't accompanied by high preference for involevement in decision-making. Physicians were less willing to share power with patients. Training in communication skills was a strong predictor of patient-centred attitudes. Finally, students' attitudes were more doctor-centred at the end of their studies. Conclusions : training in communication issues seems to be a powerful mean in devoloping patient-centred orientation in health providers, responding to the individualized needs of every greek patient

description: As fundamental parameters of the Sun, the Alfvén radius and angular momentum loss determine how the solar wind changes from sub-Alfvénic to super-Alfvénic and how the Sun spins down. We present an approach to determining the solar wind angular momentum flux based on observations from Parker Solar Probe (PSP). A flux of about $0.15\times10^{30}$ dyn cm sr$^{-1}$ near the ecliptic plane and 0.7:1 partition of that flux between the particles and magnetic field are obtained by averaging data from the first four encounters within 0.3 au from the Sun. The angular momentum flux and its particle component decrease with the solar wind speed, while the flux in the field is remarkably constant. A speed dependence in the Alfvén radius is also observed, which suggests a "rugged" Alfvén surface around the Sun. Substantial diving below the Alfvén surface seems plausible only for relatively slow solar wind given the orbital design of PSP. Uncertainties are evaluated based on the acceleration profiles of the same solar wind streams observed at PSP and a radially aligned spacecraft near 1 au. We illustrate that the "angular momentum paradox" raised by Réville et al. can be removed by taking into account the contribution of the alpha particles. The large proton transverse velocity observed by PSP is perhaps inherent in the solar wind acceleration process, where an opposite transverse velocity is produced for the alphas with the angular momentum conserved. Preliminary analysis of some recovered alpha parameters tends to agree with the results.

description: The dynamics of dislocation assemblies in deforming crystals indicate the emergence of collective phenomena, intermittent fluctuations and strain avalanches. In polycrystalline materials, the understanding of plastic deformation mechanisms depends on grasping the role of grain boundaries on dislocation motion. Here the interaction of dislocations and elastic, low angle grain boundaries is studied in the framework of a discrete dislocation representation. We allow grain boundaries to deform under the effect of dislocation stress fields and compare the effect of such a perturbation to the case of rigid grain boudaries. We are able to determine, both analytically and numerically, corrections to dislocation stress fields acting on neighboring grains, as mediated by grain boundary deformation. Finally, we discuss conclusions and consequences for the avalanche statistics, as observed in polycrystalline samples.

description: Motivated by the measurements of branching fractions of the quasi-two-body decays $B^0\to K^{*0}(f_0(980)\to )π^+π^-$ and $B^0\to ρ^0(f_0(980)\to )π^+π^-$, we study the charmless $B\to V (f_0(980)\to ) π^+π^-$ decays in the perturbative QCD approach. Supposing that $f_0(980)$ is a two-quark state and mixture of $n\bar n=(u\bar u+d\bar d)/\sqrt 2$ and $s\bar s$ with the mixing angle $θ$, we calculate the branching fractions of these decays with the new introduced $s$-wave $π^+π^-$-pair wave function. When the mixing angle $θ$ lies in the range $[135^{\circ}, 155^{\circ}]$, the calculated branching fractions of the $B^0\to K^{*0}f_0(980)\to K^{*0}π^+π^-$ and $B^0\to ρ^0f_0(980)\to ρ^0π^+π^-$ decays are in agreement with the experimental data. The branching fractions of other decays could be measured in the current LHCb and Belle II experiments. Considering the isospin symmetry, we also estimate the branching fractions of the quasi-two-body decays $B\to Vf_0(980)\to Vπ^0π^0$, which are half of those the corresponding decays $B\to Vf_0(980)\to Vπ^+π^-$. Moreover, the direct $CP$ asymmetries of these decays are also calculated, and some of them can be tested in the current experiments.

description: Policy gradient algorithms have found wide adoption in NLP, but have recently become subject to criticism, doubting their suitability for NMT. Choshen et al. (2020) identify multiple weaknesses and suspect that their success is determined by the shape of output distributions rather than the reward. In this paper, we revisit these claims and study them under a wider range of configurations. Our experiments on in-domain and cross-domain adaptation reveal the importance of exploration and reward scaling, and provide empirical counter-evidence to these claims.
Presentazione di una nuova teoria sulla valutazione del rischio e concetto di utilità, ovvero traduzione, con breve introduzione, del saggio (1738) Specimen Theoriae Novae de Mensura Sortis di Daniel Bernoulli

description: Come noto nella teoria delle decisioni il valore atteso di una particolare scelta non può essere sempre preso come criterio per determinare la decisione ottimale dal punto di vista razionale. Daniel Bernoulli in una fortunata memoria scritta nel 1731 e contenuta nel volume dei Commentarii Academiae Scientiarum Imperialis Petropolitanae pubblicato nel 1738, per primo suggerì di utilizzare in luogo del valore atteso un valore morale o utilità attesa che una persona è disposta a spendere e che dipende dal patrimonio che possiede. La proposta di Bernoulli ha avuto grandi influenza ed eco, fino ai nostri giorni, in davvero molte discipline e diversi settori di ricerca. In particolare la prospettiva aperta dal saggio è alla base del cosiddetto approccio utilitarista, sia in filosofia che in politica ed economia, per il quale ogni decisione individuale dovrebbe essere ispirata dalla necessità di massimizzare la propria utilità attesa e l’insieme delle decisioni individuali dovrebbe andare nella direzione della massimizzazione del benessere collettivo. Senza inoltrarci qui in una discussione di questi od altri importanti aspetti, riassumiamo prima brevemente l’idea di Bernoulli ed il contesto in cui fu concepita e presentiamo poi la traduzione integrale del suo articolo dall’originale latino.

description: The ICH E9(R1) addendum (2019) proposed principal stratification (PS) as one of five strategies for dealing with intercurrent events. Therefore, understanding the strengths, limitations, and assumptions of PS is important for the broad community of clinical trialists. Many approaches have been developed under the general framework of PS in different areas of research, including experimental and observational studies. These diverse applications have utilized a diverse set of tools and assumptions. Thus, need exists to present these approaches in a unifying manner. The goal of this tutorial is threefold. First, we provide a coherent and unifying description of PS. Second, we emphasize that estimation of effects within PS relies on strong assumptions and we thoroughly examine the consequences of these assumptions to understand in which situations certain assumptions are reasonable. Finally, we provide an overview of a variety of key methods for PS analysis and use a real clinical trial example to illustrate them. Examples of code for implementation of some of these approaches are given in supplemental materials.

description: Large HI shells, with diameters of hundreds of pc and expansion velocities of 10-20kms-1 are well observed features of local gas rich galaxies. These shells could well be predicted as a result of the impact of OB associations on the ISM, but doubt has been cast on this scenario by the apparent absence of OB stars close to the centres of a large fraction of these shells in recent observations of the SMC. Using Fabry-Perot scanned Halpha emission line mapping of nearby galaxy discs we have detected, in all the HII regions where the observations yield sufficient angular resolution and S:N ratio, dominant Halpha shells with radii a few tens of pc, expanding at velocities of 50-100kms-1. We have applied a simple dynamically consistent framework in which we can extrapolate the properties of the observed Halpha shells to a few 10^7yr after the formation of the OB stars. The framework includes the dynamical inputs of both winds and SNe on the surrounding ISM. The results give quantitative statistical support to the hypothesis that the Halpha emitting shells are generic progenitors of the HI shells. During the time taken for an expanding shell to reach the size of a typical HI shell, the OB association may well lose its most luminous stars so the absence of such stars near the centres of many of the HI shells is well explained in this scenario.

description: ORDER CHIROPTERA Blumenbach, 1779   Traditionally, taxonomists have divided the Chiroptera into two suborders, Megachiroptera and Microchiroptera, with the Microchiroptera comprised of two infraorders, Yinochiroptera and Yangochiroptera (Simmons 2005). Recently, molecular analyses confirmed the two suborders, Yinpterochiroptera and Yangochiroptera (Vaughan et al. 2013), despite support for the traditional taxonomy (i.e., Megachiroptera and Microchiroptera) based on echolocation (O’Leary et al. 2013).
 Four chiropteran families exist in Korea. The Rhinolophidae and Molossidae, each represented by a single species, the Miniopteridae by two species (one indigenous and one vagrant), whereas, 20 species represent the Vespertilionidae (including one vagrant species). Of the 26 species listed in Korea, we confirmed 24 species (representing 11 genera) and regard Eptesicus kobayashii and Pipistrellus pipistrellus as erroneous identifications.
