description: Introduction: There is an accelerating trend towards interdisciplinary learning and teaching activities in higher education. However, traditional discipline-based approaches to making and implementing decisions (academic governance) can be out of step. Within health professional education, there is a particular need to embrace interdisciplinary approaches to learning in the form of interprofessional education (IPE). The aim of this study was to identify academic governance models that successfully, or otherwise, supported the maintenance of quality standards of IPE programs and learning activities. Method: A 10-year literature search yielded 11 articles that addressed the IPE governance of academic standards. Results: Three models were identified: centralized, decentralized, and stand-alone. Key features of each are described with discussion on strengths and weaknesses for curriculum development, academic leadership and student learning, and the challenges of enabling interprofessional governance within traditional university academic governance structures. Conclusion: As with interdisciplinary education more broadly, there is emerging literature regarding effective governance systems to enable quality IPE within individual institutions. Educators should give careful consideration to the optimal governance model for their particular institution and context.

description: The paper is devoted to the variational analysis of the Willmore, and other L^2 curvature functionals, among immersions of 2-dimensional surfaces into a compact riemannian m-manifold (M^m,h) with m>2. The goal of the paper is twofold, on one hand, we give the right setting for doing the calculus of variations (including min max methods) of such functionals for immersions into manifolds and, on the other hand, we prove existence results for possibly branched Willmore spheres under various constraints (prescribed homotopy class, prescribed area) or under curvature assumptions for M^m. To this aim, using the integrability by compensation, we develop first the regularity theory for the critical points of such functionals. We then prove a rigidity theorem concerning the relation between CMC and Willmore spheres. Then we prove that, for every non null 2-homotopy class, there exists a representative given by a Lipschitz map from the 2-sphere into M^m realizing a connected family of conformal smooth (possibly branched) area constrained Willmore spheres (as explained in the introduction, this comes as a natural extension of the minimal immersed spheres in homotopy class constructed by Sacks and Uhlembeck in \cite{SaU}, in situations when they do not exist). Moreover, for every A>0 we minimize the Willmore functional among connected families of weak, possibly branched, immersions of the 2-sphere having prescribed total area equal to A and we prove full regularity for the minimizer. Finally, under a mild curvature condition on (M^m,h), we minimize the sum of the area with the square of the L^2 norm of the second fundamental form, among weak possibly branched immersions of the two sphere and we prove the regularity of the minimizer.

Orbital Ferromagnetism and Quantum Collapse in Stellar Plasmas

description: The possibility of quantum collapse and characteristics of nonlinear localized excitations is examined in dense stars with Landau orbital ferromagnetism in the framework of conventional quantum magnetohydrodynamics (QMHD) model including Bohm force and spin-orbit polarization effects. Employing the concepts of effective potential and Sagdeev pseudopotential, it is confirmed that the quantum collapse and Landau orbital ferromagnetism concepts are consistent with the magnetic field and mass-density range present in some white dwarf stars. Furthermore, the value of ferromagnetic-field found in this work is about the same order of magnitude as the values calculated earlier. It is revealed that the magnetosonic nonlinear propagations can behave much differently in the two distinct non-relativistic and relativistic degeneracy regimes in a ferromagnetic dense astrophysical object. Current findings should help to understand the origin of the most important mechanisms such as gravitational collapse and the high magnetic field present in many compact stars.

description: We derive non-linear commutator HS symmetry algebra, which encode unitary irreducible representations of AdS group subject to Young tableaux $Y(s_1,...,s_k)$ with $k\geq 2$ rows on $d$-dimensional anti-de-Sitter space. Auxiliary representations for specially deformed non-linear HS symmetry algebra in terms of generalized Verma module in order to additively convert a subsystem of second-class constraints in the HS symmetry algebra into one with first-class constraints are found explicitly for the case of HS fields for $k=2$ Young tableaux. The oscillator realization over Heisenberg algebra for obtained Verma module is constructed. The results generalize the method of auxiliary representations construction for symplectic $sp(2k)$ algebra used for mixed-symmetry HS fields on a flat spaces and can be extended on a case of arbitrary HS fields in AdS-space. Gauge-invariant unconstrained reducible Lagrangian formulation for free bosonic HS fields with generalized spin $(s_1,s_2)$ is derived.

description: Our aim is to transpose the polarization control by mechanical stress usually applied to single mode fibers, to the (TM01, TE01,HEev21,HEod21) annular mode family. Nevertheless, the quasi degeneracy of these four modes makes the situation more complex than with the fundamental mode HE11. We propose a simple device based on periodic perturbation and mode coupling to produce the radially polarized TM01 mode or at least one single of the four modes at the extremity of an arbitrarily long fiber, the conversion to TM01 mode being achievable by classical crystalline plates.

description: Let $(Ω,Σ,μ)$ be a measure space and $1< p < +\infty$. In this paper we show that, under quite general conditions, the set $L_{p}(Ω) - \bigcup\limits_{1 \leq q < p}L_{q}(Ω)$ is maximal spaceable, that is, it contains (except for the null vector) a closed subspace $F$ of $L_{p}(Ω)$ such that $\dim(F) = \dim(L_{p}(Ω))$. We also show that if those conditions are not fulfilled, then even the larger set $L_p(Ω) - L_q(Ω)$, $1 \leq q < p$, may fail to be maximal spaceable. The aim of the results presented here is, among others, to generalize all the previous work (since the 1960's) related to the linear structure of the sets $L_{p}(Ω) - L_{q}(Ω)$ with $q < p$ and $L_{p}(Ω) - \bigcup\limits_{1 \leq q < p}L_{q}(Ω)$.

Equilibrium policy gradients for spatiotemporal planning
Creators: name: Crowley, Mark
Publisher: name: University of British Columbia
Year: 2011

description: In spatiotemporal planning, agents choose actions at multiple locations in space over some planning horizon to maximize their utility and satisfy various constraints. In forestry planning, for example, the problem is to choose actions for thousands of locations in the forest each year. The actions at each location could include harvesting trees, treating trees against disease and pests, or doing nothing. A utility model could place value on sale of forest products, ecosystem sustainability or employment levels, and could incorporate legal and logistical constraints such as avoiding large contiguous areas of clearcutting and managing road access. Planning requires a model of the dynamics. Existing simulators developed by forestry researchers can provide detailed models of the dynamics of a forest over time, but these simulators are often not designed for use in automated planning. This thesis presents spatiotemoral planning in terms of factored Markov decision processes. A policy gradient planning algorithm optimizes a stochastic spatial policy using existing simulators for dynamics. When a planning problem includes spatial interaction between locations, deciding on an action to carry out at one location requires considering the actions performed at other locations. This spatial interdependence is common in forestry and other environmental planning problems and makes policy representation and planning challenging. We define a spatial policy in terms of local policies defined as distributions over actions at one location conditioned upon actions at other locations. A policy gradient planning algorithm using this spatial policy is presented which uses Markov Chain Monte Carlo simulation to sample the landscape policy, estimate its gradient and use this gradient to guide policy improvement. Evaluation is carried out on a forestry planning problem with 1880 locations using a variety of value models and constraints. The distribution over joint actions at all locations can be seen as the equilibrium of a cyclic causal model. This equilibrium semantics is compared to Structural Equation Models. We also define an algorithm for approximating the equilibrium distribution for cyclic causal networks which exploits graphical structure and analyse when the algorithm is exact.
Enhancing the participation of traditional authorities (chiefs) in Ghana's democratic decentralization programme: a case study of the South Tongu District Assembly of the Volta Region
Creators: name: Nyendu, Morgan
Publisher: name: University of Calgary
Year: 2006

description: Bibliography: p. 253-275
description: This dissertation examines the broader debate on the participation of traditional authorities, otherwise known as chiefs, in democratic decentralization but with particular reference to Ghana's current democratic decentralization programme (i.e. the District Assemblies system). The importance of the debate lies m the fact that there have increasingly been calls from certain sectors of society m Sub-Saharan Africa and elsewhere for collaboration between indigenous (read traditional) and modem institutions of governance so as to ensure good governance and development at the local government level. The study traces the participation of traditional authorities in local government (read decentralization) from the pre-colonial, through the colonial into the post-colonial era in what is now modem Ghana. This 'historical journey' is meant to facilitate an examination of their roles in past programmes so as to provide a basis for the evaluation of their participation in the District Assemblies system. To ensure an in-depth study, the research examines the extent to which traditional authorities in the South Tongu District of the Volta Region of Ghana have been participating in their District Assembly since the inception of the District Assemblies system in 1988. The findings from this case study are expected to provide an insight into the extent to which traditional authorities have been participating in the District Assemblies system in Ghana. The study discusses those findings and their implications for both the institution of traditional authority and the decentralization programme. Further, lessons drawn from the study form a basis for recommendations on how to improve upon the programme so as to enhance local governance and development both in Ghana and in other countries pursuing similar programmes.

In contrast to previous approaches where an optimal set of measurements is decided in advance of the experiment, we allow for measurements to be adaptively and efficiently re-optimised depending on data collected so far. We develop an adaptive statistical framework based on Bayesian inference and Shannon's information, and demonstrate a ten-fold reduction in the total number of measurements required as compared to non-adaptive methods, including mutually unbiased bases.

description: An interval graph is proper iff it has a representation in which no interval contains another. Fred Roberts characterized the proper interval graphs as those containing no induced star $K_{1,3}$. Proskurowski and Telle have studied $q$-proper graphs, which are interval graphs having a representation in which no interval is properly contained in more than $q$ other intervals. Like Roberts they found that their classes of graphs where characterized, each by a single minimal forbidden subgraph. This paper initiates the study of $p$-improper interval graphs where no interval contains more than $p$ other intervals. This paper will focus on a special case of $p$-improper interval graphs for which the minimal forbidden subgraphs are readily described. Even in this case, it is apparent that a very wide variety of minimal forbidden subgraphs are possible.

description: Experts agree that keeping systems up to date is a powerful security measure. Previous work found that users sometimes explicitly refrain from performing timely updates, e.g., due to bad experiences which has a negative impact on end-user security. Another important user group has been investigated less extensively: system administrators, who are responsible for keeping complex and heterogeneous system landscapes available and secure. In this paper, we sought to understand administrators’ behavior, experiences, and attitudes regarding updates in a corporate environment. Based on the results of an interview study, we developed an online survey and quantified common practices and obstacles (e.g., downtime or lack of information about updates). The findings indicate that even experienced administrators struggle with update processes as the consequences of an update are sometimes hard to assess. Therefore, we argue that more usable monitoring and update p

description: Objectives: Peer review is a powerful tool that steers the education and practice of medical researchers but may allow biased critique by anonymous reviewers. We explored factors unrelated to research quality that may influence peer review reports, and assessed the possibility that sub-types of reviewers exist. Our findings could potentially improve the peer review process. Methods: We evaluated the harshness, constructiveness and positiveness in 596 reviews from journals with open peer review, plus 46 reviews from colleagues’ anonymously reviewed manuscripts. We considered possible influencing factors, such as number of authors and seasonal trends, on the content of the review. Finally, using machine-learning we identified latent types of reviewer with differing characteristics. Results: Reviews provided during a northern-hemisphere winter were significantly harsher, suggesting a seasonal effect on language. Reviews for articles in journals with an open peer review policy were significantly less harsh than those with an anonymous review process. Further, we identified three types of reviewers: nurturing, begrudged, and blasé. Conclusion: Nurturing reviews were in a minority and our findings suggest that more widespread open peer reviewing could improve the educational value of peer review, increase the constructive criticism that encourages researchers, and reduce pride and prejudice in editorial processes.

Towards Feynman rules for Mellin amplitudes in AdS/CFT
Creators: name: Paulos, Miguel F.
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate the use of the embedding formalism and the Mellin transform in the calculation of tree-level conformal correlation functions in $AdS$/CFT. We evaluate 5- and 6-point Mellin amplitudes in $ϕ^3$ theory and even a 12-pt diagram in $ϕ^4$ theory, enabling us to conjecture a set of Feynman rules for scalar Mellin amplitudes. The general vertices are given in terms of Lauricella generalized hypergeometric functions. We also show how to use the same combination of Mellin transform and embedding formalism for amplitudes involving fields with spin. The complicated tensor structures which usually arise can be written as certain operators acting as projectors on much simpler index structures - essentially the same ones appearing in a flat space amplitude. Using these methods we are able to evaluate a four-point current diagram with current exchange in Yang-Mills theory.

description: This paper aims to shed some light on the concept of virality - especially in social networks - and to provide new insights on its structure. We argue that: (a) virality is a phenomenon strictly connected to the nature of the content being spread, rather than to the influencers who spread it, (b) virality is a phenomenon with many facets, i.e. under this generic term several different effects of persuasive communication are comprised and they only partially overlap. To give ground to our claims, we provide initial experiments in a machine learning framework to show how various aspects of virality can be independently predicted according to content features.

Discussion forums are a key component of most online courses, and are often included as homework for face-to-face courses as well. In this session, the presenters will share examples of discussion forum assignments that have yielded high student participation, as well as different ways to set up and facilitate discussion forums, including student-led and small-group discussion forums. The presenters will also share sample grading rubrics for discussion forums, and strategies to plan ahead for issues that may come up. The examples and strategies will come from Columbia University’s School of Social Work, which offers a fully online Master’s of Science in Social Work program.
This interactive session will begin with polls to learn why participants have chosen to attend; the presenters will use the poll results to tailor the use of time for the different sections of the presentation. In addition, throughout the presentation, participants will have the opportunity to share their own strategies, ask questions, and add to their toolkits of strategies for online discussion forums. Strategies discussed will appeal to a range of budgets and classroom staffing, so as to be applicable and sustainable at any school.
Comparative biochemistry of three recently evolved hexachlorocyclohexane dehydrochlorinase variants
Creators: name: Mohd Pushiri, Noor Hafizah
Publisher: name: The Australian National University
Year: 2019

description: The synthetic compound hexachlorocyclohexane (HCH) was widely used as a pesticide for several decades from the 1940s onwards but concerns about detrimental off-target effects have led to progressive reductions in its use in most countries since the 1970s. Even so, its persistence in the environment has meant it remains a concern and bioremediation options are therefore being explored to rehabilitate HCH-contaminated environments. Part of the research towards bioremediation solutions has involved studies of the bacterial enzymes responsible for the biodegradation of HCH, one of the key enzymes being the HCH-dehydrochlorinase LinA. Previous work has suggested LinA can catalyse two successive eliminations of trans-diaxial H-Cl pairs from various HCH isomers. This thesis compares the biochemistry of three different types of LinA, namely the LinA-type1 LinA2B90A, the LinA-type2 LinA1B90A and the novel LinA-type3 LinALL02. LinALL02 was found to differ from LinA1B90A and LinA2B90A in several respects, but particularly in its preference to degrade the delta-HCH isomer over the gamma-HCH isomer in the first elimination reaction and its ability to produce all three trichlorobenzene isomers (TCBs) as eventual dead-end products following the second elimination reaction. Valines at position 44 and 64 of LinALL02 were hypothesised as having roles in these unique characteristics and this hypothesis was supported to a degree by empirical analysis of synthetic mutants at these positions. Additionally, differences were found between the three LinA enzymes in their degradation of the (+)-alpha-HCH versus (-)-alpha-HCH enantiomers, and greater preferences were observed in assays of whole E.coli cells expressing the enzymes than in assays with purified enzymes. The variants also differed in their enantiopreferences in the second elimination reactions, specifically among the beta-, gamma-, and delta-pentachlorocyclohexenes (PCCHs) which are respectively produced from alpha-, gamma-, and delta-HCH degradation in the first elimination reactions. While most of my data are consistent with the accepted view that LinA works by eliminating trans-diaxial H-Cl pairs, I found it necessary to invoke syn- and anti-1,4-elimination of H-Cl pairs to account for the activities seen with delta- and beta-PCCH, respectively. A possible role for LinA in the previously proposed spontaneous production of TCBs from the proximal product of PCCH degradation, tetrachlorocyclohexadiene (TCDN), was also discussed. Molecular dynamics trajectories were performed for the three enzymes with alpha-, gamma-, and delta-HCH, and their corresponding PCCHs, but it was found that the percentage of time which substrates spent in productive poses in the active sites of the enzymes were not correlated to the enzymes' activity on the substrates.
Learning Input Tokens for Effective Fuzzing
Creators: name: Mathis, Björn
name: Gopinath, Rahul
name: Zeller, Andreas
Publisher: name: CISPA
Year: 2023

description: Modern fuzzing tools like AFL operate at a lexical level: They explore the input space of tested programs one byte after another. For inputs with complex syntactical properties, this is very inefficient, as keywords and other tokens have to be composed one character at a time. Fuzzers thus allow to specify dictionaries listing possible tokens the input can be composed from; such dictionaries speed up fuzzers dramatically. Also, fuzzers make use of dynamic tainting to track input tokens and infer values that are expected in the input validation phase. Unfortunately, such tokens are usually implicitly converted to program specific values which causes a loss of the taints attached to the input data in the lexical phase. In this paper we present a technique to extend dynamic tainting to not only track explicit data flows but also taint implicitly converted data without suffering from taint explosion. This extension makes it possible to augment existing techniques and automatically infer a set of tokens and seed inputs for the input language of a program given nothing but the source code. Specifically targeting the lexical analysis of an input processor, our lFuzzer test generator systematically explores branches of the lexical analysis, producing a set of tokens that fully cover all decisions seen. The resulting set of tokens can be directly used as a dictionary for fuzzing. Along with the token extraction seed inputs are generated which give further fuzzing processes a head start. In our experiments, the lFuzzer-AFL combination achieves up to 17% more coverage on complex input formats like JSON, LISP, tinyC, and JavaScript compared to AFL.

description: We propose a new segmentation evaluation metric, called segmentation similarity (S), that quantifies the similarity between two segmentations as the proportion of boundaries that are not transformed when comparing them using edit distance, essentially using edit distance as a penalty function and scaling penalties by segmentation size. We propose several adapted inter-annotator agreement coefficients which use S that are suitable for segmentation. We show that S is configurable enough to suit a wide variety of segmentation evaluations, and is an improvement upon the state of the art. We also propose using inter-annotator agreement coefficients to evaluate automatic segmenters in terms of human performance.

description: Background: Widespread concerns about new medical graduates’ ‘work readiness’ may reflect, in part, differences in mandatory learning outcomes for medical students and new medical graduates. Purpose: To examine differences between required medical student and PGY1 (first year resident) training program outcomes, and the nature and magnitude of these differences. Method: Comparison, systematic identification and thematic analysis of differences between the graduate outcomes in the Australian Medical Council Standards for the Assessment and Accreditation of Primary Medical Programs and those in the New Zealand Curriculum Framework for Prevocational Training. Results: The relationship between these outcome statements were categorized as: essentially similar; continuity; partial discontinuity; and complete discontinuity of learning trajectory. Areas requiring substantial new learning may reflect medical schools’ focus on individual student performance, and on learning and assessments based on single episodes of often uncomplicated illness. This contrasted with a post-graduate focus on integrated health care delivery by teams and management of complex illnesses over the whole patient care journey. Conclusions: Characterizing these marked differences between pre-graduate and postgraduate standards, within a trajectory of learning, explains some of the difficulties in students’ preparation for work readiness. These could inform learning interventions to support new graduates’ professional development to ensure patient safety. Development and revision of accreditation standards should include formal review against the expectations of the preceding and succeeding phases of learning.

description: Medical curricula have historically been designed in a top-down approach, usually excluding students. While Delphi panels have been used as a tool for medical education curricula design, none have been conducted in Ecuador. In addition, no such approach has ever included students both as panelists and researchers. Four Delphi panels were developed and conducted using a participatory approach that allowed medical students to take part both as expert panelists and researchers: specifically, students developed the questionnaire and conducted a qualitative synthesis. Questionnaire responses were anonymized and dispatched online to panelists. The information was organized and collected to develop the qualitative syntheses and prepare the final statements. Thirty-two medical students participated between February and May 2018. A total of 32 questions were developed, corresponding to five different categories. For some questions, consensus was reached; for other questions, general statements were obtained. Discussion and conclusion: Developing the questionnaire, responding to it and analyzing the answers allowed students to raise significant concerns regarding medical education topics proposing relevant policy and curricula change. Participatory Delphi panels can be an efficient tool to obtain organized feedback, improve student class involvement, and promote research skills.

description: Handel ludźmi jest jednym z deliktów, z którym mamy do czynienia na ziemiach polskich od najdawniejszych czasów. Handel kobietami pozostawał głównie w związku z prostytucją, natomiast handel mężczyznami z wykorzystaniem w niewolniczej pracy. Zjawisko to było przedmiotem regulacji wszystkich polskich dwudziestowiecznych kodyfikacji karnych. Oprócz rozwiązań kodeksowych wpływ na walkę z handlem ludźmi miały także zobowiązania przyjęte przez Polskę wynikające z prawa międzynarodowego. Walkę z handlem ludźmi komplikuje również fakt powiązania tego deliktu z innymi najpoważniejszymi przestępstwami przewidzianymi w prawie karnym. Czynniki te powodują, że działania mające na celu zniesienie handlu ludźmi są nie w pełni skuteczne.

description: Phishing websites are still a major threat in today's Internet ecosystem. Despite numerous previous efforts, similarity-based detection methods do not offer sufficient protection for the trusted websites -- in particular against unseen phishing pages. This paper contributes VisualPhishNet, a new similarity-based phishing detection framework, based on a triplet Convolutional Neural Network (CNN). VisualPhishNet learns profiles for websites in order to detect phishing websites by a similarity metric that can generalize to pages with new visual appearances. We furthermore present VisualPhish, the largest dataset to date that facilitates visual phishing detection in an ecologically valid manner. We show that our method outperforms previous visual similarity phishing detection approaches by a large margin while being robust against a range of evasion attacks.

Year: 2019
Subjects: L-LIN/02 Didattica delle lingue moderne

description: The purpose of this article is to offer an analysis of the grammar resources for teaching and learning Russian as an L2 (grammar books, textbooks, method books) published in Italian between 1882 and December 1917 – therefore, leaving out books published after the post-Revolution reform of Russian orthography. The analysis will focus on their publishing, textual, structural and content aspects; the use of different linguistic registers of the L2 and their corresponding purposes; the target audience. Finally, the books’ methodological and glottodidactic approaches for teaching and learning Russian as an L2 will be discussed.

description: The neutrino oscillations in the field of a rotating deformed mass is investigated. The phase shift is evaluated in the case of weak field limit, slow rotation and small deformation. To this aim the Hartle-Thorne metric is used, which is an approximate solution of the vacuum Einstein equations accurate to second order in the rotation parameter $a/M$ and to first order in the mass quadrupole moment $q$. Implications on atmospheric, solar and astrophysical neutrinos are discussed.

Women authors of ELT materials in Italy (1896-1918)

Subjects: L-LIN/01 Glottologia e linguistica

description: The aim of this paper is twofold. Firstly, I present the findings of bibliographical research conducted in an attempt to identify first women authors of ELT materials in Italy. It appears that, in the period between 1896 and 1918, twenty-three different women authors produced at least one ELT publication each. Secondly, I focus on two women authors whose contribution to promoting the learning and teaching of English in that period was particularly significant. I argue that Pia Padovani’s (1904, 1906) and Anna Benedetti’s (1915) views on the goals, priorities and language teaching methodologies are of particular relevance and I analyse the prefaces to their textbooks in an attempt to amplify our knowledge of the history of English language teaching in the early 20th-century Italy.

description: We show how a parameterized family of maps of the spine of a manifold can be used to construct a family of homeomorphisms of the ambient manifold which have the inverse limits of the spine maps as global attractors. We describe applications to unimodal families of interval maps, to rotation sets, and to the standard family of circle maps.

Towards Automated Testing and Robustification by Semantic Adversarial Data Generation

description: Widespread application of computer vision systems in real world tasks is currently hindered by their unexpected behavior on unseen examples. This occurs due to limitations of empirical testing on finite test sets and lack of systematic methods to identify the breaking points of a trained model. In this work we propose semantic adversarial editing, a method to synthesize plausible but difficult data points on which our target model breaks down. We achieve this with a differentiable object synthesizer allowing to modify appearances of an object instance while maintaining its original pose. Constrained adversarial optimization of object appearance through this synthesizer produces rare/difficult versions of an object instance which fool the target object detector. Experiments show that our approach is effective in synthesizing difficult test data, dropping the performance of YoloV3 detector by more than 20 mAP points by changing the appearance of a single object and discovering failure modes of the model. We also demonstrate that the generated semantic adversarial data can be used to robustify the detector through data augmentation, consistently improving its performance in both standard and out-of-dataset-distribution test sets, across three different datasets.

description: In 1832, Bachi published a work that is considered the first university grammar book of Spanish for learners of Italian, who were not Italian native speakers. It was dedicated to students of Harvard University (USA). As far as Italian is concerned – although there are some other previous texts (Spagnolo de Monaci and D'Ovidio 1879) – Egidio Gorra’s work (Lingua e letteratura spagnuola delle origini), published by Hoepli in Milan (1898), constitutes the first historical grammar book specifically dedicated to a higher-education audience. It is a work intended for students of the Faculty of Letters of the University of Pavia, which includes many of the typical features of a university textbook. The purpose of the paper is to consider this characterization in light of previous Spanish grammars for Italian speakers, highlighting those elements that distinguish it as a university textbook.

description: We study the maximum-confidence (MC) measurement strategy for discriminating among nonorthogonal symmetric qudit states. Restricting to linearly dependent and equally likely pure states, we find the optimal positive operator valued measure (POVM) that maximizes our confidence in identifying each state in the set and minimizes the probability of obtaining inconclusive results. The physical realization of this POVM is completely determined and it is shown that after an inconclusive outcome, the input states may be mapped into a new set of equiprobable symmetric states, restricted, however, to a subspace of the original qudit Hilbert space. By applying the MC measurement again onto this new set, we can still gain some information about the input states, although with less confidence than before. This leads us to introduce the concept of "sequential maximum-confidence" (SMC) measurements, where the optimized MC strategy is iterated in as many stages as allowed by the input set, until no further information can be extracted from an inconclusive result. Within each stage of this measurement our confidence in identifying the input states is the highest possible, although it decreases from one stage to the next. In addition, the more stages we accomplish within the maximum allowed, the higher will be the probability of correct identification. We will discuss an explicit example of the optimal SMC measurement applied in the discrimination among four symmetric qutrit states and propose an optical network to implement it.

description: We investigate single photon generation from individual self-assembled InGaAs quantum dots coupled to the guided optical mode of a GaAs photonic crystal waveguide. By performing confocal microscopy measurements on single dots positioned within the waveguide, we locate their positions with a precision better than 0.5 \mum. Time-resolved photoluminescence and photon autocorrelation measurements are used to prove the single photon character of the emission into the propagating waveguide mode. The results obtained demonstrate that such nanostructures can be used to realize an on-chip, highly directed single photon source with single mode spontaneous emision coupling efficiencies in excess of beta~85 % and the potential to reach maximum emission rates >1 GHz.
