description: We constrain the velocity spectral distribution of global-scale solar convective cells at depth using techniques of local helioseismology. We calibrate the sensitivity of helioseismic waves to large-scale convective cells in the interior by analyzing simulations of waves propagating through a velocity snapshot of global solar convection via methods of time-distance helioseismology. Applying identical analysis techniques to observations of the Sun, we are able to bound from above the magnitudes of solar convective cells as a function of spatial convective scale. We find that convection at a depth of $r/R_\odot = 0.95$ with spatial extent $\ell <20$, where $\ell$ is the spherical harmonic degree, comprise weak flow systems, on the order of 15 m/s or less. Convective features deeper than $r/R_\odot = 0.95$ are more difficult to image due to the rapidly decreasing sensitivity of helioseismic waves.

description: We combine new Spitzer Space Telescope observations in the mid- and far-infrared with SCUBA 850 micron observations to improve the measurement of dust temperatures, masses and luminosities for 11 galaxies of the SCUBA Local Universe Galaxy Survey (SLUGS). By fitting dust models we measure typical dust masses of 10E7.9 M_sol and dust luminosities of ~ 10E10 L_sol, for galaxies with modest star formation rates. The data presented in this paper combined with previous observations show that cold dust is present in all types of spiral galaxies and is a major contributor to their total luminosity. Because of the lower dust temperature of the SCUBA sources measured in this paper, they have flatter Far-IR nu F_nu(160um)/nu F_nu(850um) slopes than the larger Spitzer Nearby Galaxies Survey (SINGS), the sample that provides the best measurements of the dust properties of galaxies in the nearby universe. The new data presented here added to SINGS extend the parameter space that is well covered by local galaxies, providing a comprehensive set of templates that can be used to interpret the observations of nearby and distant galaxies.

description: Valley-related multiple Hall effect in two-dimensional lattice is of notable interest both for its fundamental physics and for its potential applications. In this work, by means of a low energy kp model analysis, a mechanism of producing valley-related multiple Hall effect in hexagonal lattice via strain engineering is proposed, and a general picture of valley-contrasted band inversion is developed. Through first-principles calculations, this mechanism is further established in a ferromagnetic hexagonal lattice of single-layer ScI2. Single-layer ScI2 prefers in-plane magnetization and exhibits neither anomalous valley Hall effect nor valley-polarized quantum anomalous Hall effect in nature. Remarkably, these two Hall effects emerge simultaneously in this system under 4.705% tensile strain and disappear simultaneously when further increasing strain, suggesting the exotic valley-related multiple Hall effect. The underlying physical mechanism is revealed using a model analysis and is generally applicable. Our work greatly enriches the valley-related physics.

L'invention de l'Orthodoxie. Religion et Modernité dans le discours nationaliste roumain du XIX-ème et du XX-ème siècles

description: Our thesis entitled The Invention of Orthodoxy. Religion and Modernity in Romanian nationalist discourse from the XIXth to the XXth century is intended to be a history of the idea of “Romanianess” which brings together, in a structural as well as in a conceptual dimension, three major themes: Romanian Orthodoxy, Modernity and the Political. Having as premise for the study of the Romanian case the simultaneous genesis of the religious and political communities, from the Middle Ages to Modernity, the purpose of our inquiry is to formulate a theologico-political definition of ‘’Romanian Orthodoxy’’. Thus, within a main theoretical framework that values the contributions of Carl Schmitt, Michel Foucault and Reinhart Koselleck, our analysis of selected texts that go from the 1860’s to the 1940’s tries to answer the question regarding the relationship between Romanian Orthodoxy and Modernity, as well as its reflection upon the political identity and organisation of the Romanian society. 
	Considering the political context of the events that underline our conceptual focus, we consider that the proper answer to our investigation lies within the logic of multiplicity; namely, we refer to a plural Romania which is divided, at the beginning of the XXth century, between Traditionalism and Modernity, between a massive rural, agrarian society and an urban minority elite, striving to single out, in an phenomenological approach, the “Romanian way”. Secondly, we refer to a plural Modernity, which is at the same time social, cultural, religious and political. Thirdly, the logic of multiplicity applies as well in the interpretation of the fractures present within the religious nationalist discourse; namely, the rejection of Orthodoxy during the XIXth century, as it was considered an impediment in Romania’s path to adopting western modernity and later on, starting with the 1930, the restoration of the “Orthodox ethos” as a source of cultural and political values of the Romanian nation.

Corrections to Kusnetz Method for Measurements of Radon Progeny Concentrations in Air

description: In 1956, H.L. Kusnetz proposed a quick method for radon progeny concentration measurement in mine atmosphere using a single gross-alpha count of a membrane-filtered air. The method is still widely used today and is based on a number of impractical assumptions. An instantaneous sampling time (less than ten seconds), is one of these assumptions that ignores the build-up and decay of the progeny on the filter paper during the sampling period. Of special concern is the 214Bi decay during the sampling period, since 214Po alphas are lost during the sampling time and cannot be accounted for during the counting time. In addition, the method assumes that 214Bi activity during the counting period is constant. This inaccurate assumption can result in a smaller count rate, especially when counting times are long. Hence underestimated working levels are expected when using Kusnetz factors without correcting for the sampling and counting times. In this technical report, exact sampling and counting time corrections to the method are provided along with the updated Kusnetz factors that correspond to common equilibrium conditions to correctly estimate the Working Level in air. Additionally, time corrections to the commonly used self-absorption correction formula and the lower level of detectability (LLD) equation used for any sample measurement are given.

description: In this paper, we review our novel information geometrodynamical approach to chaos (IGAC) on curved statistical manifolds and we emphasize the usefulness of our information-geometrodynamical entropy (IGE) as an indicator of chaoticity in a simple application. Furthermore, knowing that integrable and chaotic quantum antiferromagnetic Ising chains are characterized by asymptotic logarithmic and linear growths of their operator space entanglement entropies, respectively, we apply our IGAC to present an alternative characterization of such systems. Remarkably, we show that in the former case the IGE exhibits asymptotic logarithmic growth while in the latter case the IGE exhibits asymptotic linear growth. At this stage of its development, IGAC remains an ambitious unifying information-geometric theoretical construct for the study of chaotic dynamics with several unsolved problems. However, based on our recent findings, we believe it could provide an interesting, innovative and potentially powerful way to study and understand the very important and challenging problems of classical and quantum chaos.

description: Big data and its potential, use, and hopes seem to grow more valuable for commercial and research purposes alike. Nevertheless, problems start to arise as soon as the technical and epistemic potential of big data is overemphasized. Big data, like any other traces of human behavior, must be contextualized. This seems even more important since all types of digital traces are molded by specific operations and procedures as well as methods inscribed into digital infrastructures. These infrastructures are the necessary precondition for the emergence of digital traces, yet they pose a challenge for research because they are by no means static, but rather moving continuously. By reconstructing the trajectory of the UDID (unique device identifier) and its contested role within Apple’s App Store ecology, this article presents an empirical perspective on how the contexts and preconditions of tracing capabilities are the result of continuous negotiation processes. The method presented in the article bridges the debates on the moving architectures of digital media and the search for suitable process-driven approaches.

description: Bacterial small regulatory RNAs (sRNAs) are posttranscriptional regulators involved in stress responses. These short non-coding transcripts are synthesised in response to a signal, and control gene expression of their regulons by modulating the translation or stability of the target mRNAs, often in concert with the RNA chaperone Hfq. Characterization of a Hfq knock out mutant in Neisseria meningitidis revealed that it has a pleiotropic phenotype, suggesting a major role for Hfq in adaptation to stresses and virulence and the presence of Hfq-dependent sRNA activity. Global gene expression analysis of regulated transcripts in the Hfq mutant revealed the presence of a regulated sRNA, incorrectly annotated as an open reading frame, which we renamed AniS. The synthesis of this novel sRNA is anaerobically induced through activation of its promoter by the FNR global regulator and through global gene expression analyses we identified at least two predicted mRNA targets of AniS.
We also performed a detailed molecular analysis of the action of the sRNA NrrF,. We demonstrated that NrrF regulates succinate dehydrogenase by forming a duplex with a region of complementarity within the sdhDA region of the succinate dehydrogenase transcript, and Hfq enhances the binding of this sRNA to the identified target in the sdhCDAB mRNA; this is likely to result in rapid turnover of the transcript in vivo. 
In addition, in order to globally investigate other possible sRNAs of N. meningitdis we Deep-sequenced the transcriptome of this bacterium under both standard in vitro and iron-depleted conditions. This analysis revealed genes that were actively transcribed under the two conditions. We focused our attention on the transcribed non-coding regions of the genome and, along with 5’ and 3’ untranslated regions, 19 novel candidate sRNAs were identified. Further studies will be focused on the identification of the regulatory networks of these sRNAs, and their targets.
Recreation impact on campsite vegetation

description: The study purpose was to determine the occurrence and magnitude of understory vegetation change caused by the occupants of campsites, to determine the magnitude of screening provided by overstory vegetation, to assess quantitatively the reliability of battery operated electromagnetic digital traffic counters, and to correlate permit system data to traffic counter data. The original study design provided for cross-sectional data from twenty selected campsites within two campgrounds situated within two western Canada National Parks. Lack of visitors at one campground and time constraints at the other necessitated abandonment of fifteen sample campsites. The final field study was concerned with changes in understory vegetation, occupancy and screening of five selected campsites in Wapiti campground of Jasper National Park, the numbers and some characteristics of the parties entering the study area, and the numbers of parties entering the campground. The study period was July 1 to September 1, 1970. Sixteen sample days were randomly selected to provide double backed days, evenly distributed between weekdays and weekends. Four experimental plots and one control plot, each one square meter in area, were located within each sample campsite. Within these plots understory vegetation change was determined by scanning the vegetation understory through a clear plastic grid at the beginning and end of the study period. Total vegetation cover within the experimental plots was reduced from a mean of 37 percent to 17 percent. Total vegetation within the control plots was reduced from a mean of 46 percent to 35 percent. Statistical analysis revealed a significant reduction of total vegetation within the experimental plots and within the control plots. Occupancy of the sample campsites was observed each hour from 8:00 a.m. to 8:00 p.m. during the sample days. No correlation could be found between changes in vegetation cover and occupancy of the sample sites. Overstory vegetation screening between campsites, determined by means of a pantallometer, ranged from 25 to 50 percent. Electromagnetic digital traffic counters were found to be a reliable and statistically acceptable method of collecting traffic data. Correlation of campground permit sales to traffic entering the campground indicated that each vehicle entered the campground approximately twice daily.

description: INTRODUCTION: A relationship between inflammatory response and coagulation is suggested by many observations. In particular, pro-inflammatory cytokines, such as TNFalpha, promote the activation of coagulation and reduce the production of anticoagulant molecules. It is known that inflammatory bowel diseases show a prothrombotic state and a condition of hypercoagulability. Aim of our study was to evaluate whether anti-TNFalpha therapy induces changes in the levels of coagulation activation markers in IBD patients. MATERIALS AND METHODS: We analyzed 48 plasma samples obtained before and 1 hour after 24 infliximab infusions (5 mg/kg) in 9 IBD patients (5 men and 4 women; mean age: 47.6+17.6 years; 4 Crohn's disease, 4 Ulcerative Colitis,1 Indeterminate Colitis). F1+2 and D-dymer levels were measured in each sample using ELISA methods.The data were statistically analyzed by means of Wilcoxon matched paired test. RESULTS: Median F1+2 levels were markdely reduced 1 hour after anti-TNFα infusion (median pre-infusion levels were 247.0 pmol/L and median post-infusion levels were 185.3 pmol/L) (p<0.002). Median D-dymer levels were also significantly reduced, from 485.2 ng/mL to 427.6 ng/mL (p< 0.001). These modifications were more evident in patients naive for infliximab therapy (p<0.02 for F1+2 and p<0.02 for D-dymer) and in Crohn's disease compared with Ulcerative Colitis patients (p=0.01 for F1+2 and p<0.007 for D-dymer).CONCLUSIONS: Infusion of infliximab significantly reduces the activation of coagulation cascade in IBD patients. This effect is early enough to suggest a direct effect of infliximab on the coagulation cascade and a possible new anti-inflammatory mechanism of action of this molecule.

description: We study an anisotropic two-dimensional non-Hermitian Lieb lattice, where the staggered gain and loss present in the horizontal and vertical directions, respectively. The intra-cell nonreciprocal coupling generates magnetic flux enclosed in the unit cell of the Lieb lattice and creates nontrivial topology. The active and dissipative topological edge states are along the horizontal and vertical directions, respectively. The two-dimensional non-Hermitian Lieb lattice also supports passive topological corner state. At appropriate magnetic flux, the non-Hermiticity can alter the corner state from one corner to the opposite corner as the non-Hermiticity increases. The gapless phase of the Lieb lattice is characterized by different configurations of exceptional points in the Brillouin zone. The topology of the anisotropic non-Hermitian Lieb lattices can be verified in many experimental platforms including the optical waveguide lattices, photonic crystals, and electronic circuits.

Ni una más. International cooperation against gender-based discrimination: the femicide case in Ciudad Juárez, Chihuahua,

description: The femicide in Ciudad Juárez is a story made of extreme violence against women for different
reasons, by different actors, under different circumstances, and following different behavioural
patterns. All within a gender discrimination frame based on the idea that women are inferior,
interchangeable and disposable according to the patriarchal hierarchy still present in Mexico, but
strongly reinforced by a sort of conspiracy of silence provoked either by the high impunity rate, the
governmental incompetence to solve the crimes, or the general indifference of the population. It is
the story of hundreds of kidnapped, raped, in many cases tortured, and murdered young women in
the border between Mexico and the United States. The murders first came into light in 1993 and up
to now young women continue to “disappear” without any hope of bringing the perpetrators to
justice, stopping impunity, convicting the assassins, and bringing justice to the families of the
deceased girls and women.
The main questions about femicide in Ciudad Juárez seem to be: why were they brutally
assassinated?, why most of the crimes have not been solved yet?, why and how is Ciudad Juárez
different from other border cities with the same characteristics?, which powers are behind those
crimes in a city that implies mainly women as its labor force, and which has the lowest
unemployment rate in the whole country? But there are also many other questions dealing more
with the context, the Juarences’ lifestyles, the eventual hidden powers behind the crimes, the
possible murderers’ reasons, the response of the local civil society, or the international community
actions to fight against femicide there, among many other things, that are still waiting for an answer
and that this paper will ‘narrate’ in order to provide a holistic panorama for the readers. But above
all there is the need to remember that every single woman or girl assassinated there had a name, an
identity, a family, a story to be told time after time and as many times as necessary, in order to
avoid accepting these crimes just as statistics, as cold numbers that might make us forget the human
tragedy that has been flagellating the city since 1993. We must remember as well that their deaths
express gender oppression, the inequality of the relations between what is male and what is female,
a manifestation of domination, terror, social extermination, patriarchal hegemony, social class and
impunity.
The city is the perfect mirror where all the contradictions of globalization get reflected. It is there
where all the globalization evils are present and survive by sucking their women’s blood. It is a
city where some concepts such as gender, migration and power are closely related with a negative
connotation.

description: Loaded with 16% of the world’s population, India is a challenged country.
More than a third of its citizens live below the poverty line - on less than a dollar a day. These people have no proper electricity, no proper drinking water supply, no proper sanitary facilities and well over 40% are illiterates.
More than 65% live in rural areas and 60% earn their livelihood from agriculture. Only a meagre 3.63% have access to telephone and less than 1% have access to a computer.
Therefore, providing access to timely information on agriculture, weather, social, health care, employment, fishing, is of utmost importance to improve the conditions of rural poor.
After some introductive chapters, whose function is to provide a comprehensive framework – both theoretical and practical – of the current rural development policies and of the media situation in India and Uttar Pradesh, my dissertation presents the findings of the pilot project entitled “Enhancing development support to rural masses through community media activity”, launched in 2005 by the Department of Mass Communication and Journalism of the Faculty of Arts of the University of Lucknow (U.P.) and by the local NGO Bharosa.
The project scope was to involve rural people and farmers from two villages of the district of Lucknow (namely Kumhrava and Barhi Gaghi) in a three-year participatory community media project, based on the creation, implementation and use of a rural community newspaper and a rural community internet centre.
Community media projects like this one have been rarely carried out in India because the country has no proper community media tradition: therefore the development of the project has been a challenge for the all stakeholders involved.
Financial implications and some costs and benefits of logging guidelines in the Chilliwack provincial forest
Creators: name: Benskin, Henry J.
Publisher: name: University of British Columbia
Year: 2010

description: The financial implications and some of the costs and benefits of two sets of logging guidelines were examined in two sample drainages in the Chilliwack Provincial Forest. Time limitations and lack of data on non-timber resource impacts prevented a full quantitative evaluation of all costs and benefits. Instead, an analysis of the financial impact of these guidelines on the timber resource was undertaken, and supported by a qualitative discussion of environmental, social and income distribution effects. The potential variation in the system was demonstrated by a simulation approach to the financial evaluation. There still is much uncertainty in most of the assumptions and research and improved methods could provide more precise answers. The financial analysis showed that the alternative patch cutting system, common to both sets of guidelines, was the main contributing factor to increased logging costs. The more extensive basis for harvesting under this system was found to result in as much as a 60% decline in potential economic rent per developed acre, without any consideration of increases in physical harvesting costs. The size of the increase in physical logging costs per unit was found to be very sensitive to interest rates and to the length of the leave period between consecutive harvesting passes. Application of the 1972 Coast Logging Guidelines to harvesting-operations in the Chilliwack Provincial Forest was found to result in an extra annual cost, ranging from between $0,632 million to $6,645 million for the next 24 years. A figure of $1,423 million was considered to be the most realistic estimate of the extra costs resulting from the guidelines. The alternate patch cutting system with long leave periods -may aggravate instability of those small undiversified communities which are highly dependent upon the local timber processing industries for employment. Analysis of the costs and benefits of the guidelines as they affect other resource values revealed that they may be an inefficient means for attaining multiple use objectives. It appeared likely that problems of erosion, sedimentation and aesthetic impact may even be increased overall, because of the more extensive basis for forest development. There still is a need for much investigation of the quantitative aspects of harvesting impacts on forest land resources. In addition the analyses should be extended to other units, and guideline effects evaluated by mathematical modelling.

description: This practice-led research project focuses on the investigation of alternative surface application techniques for a ceramic substrate with the aim of developing a new method to adhere glaze to a ceramic body. My research question, ‘How can molten glaze be applied to ceramic substrates allowing successful fusing of materials?’ is investigated by integrating the ceramic raku process with methods from both metalsmithing and hot glass production. By melting glaze material within a crucible, then pouring onto a bisque ceramic body, glaze manipulation, while the glaze was still molten, was undertaken. By trialing and testing an easily replicated glazing technique, this research enabled experimentation with a new range of possible surface effects achievable in the raku kiln, thereby adding knowledge for the research community and providing further developmental avenues for the ceramic practitioner. To this date, no research had been published covering this aspect of glazing, yet this is an important area of research. As a result of developing this project, a range of unforeseen Occupational Health and Safety issues regarding conducting such research in ceramic studios, both commercial and private, has been investigated. This is discussed, along with the ramifications of this outcome for both academic and professional ceramic artists. The thesis consists of a creative component in the form of a body of creative work created during the project, and a related scholarly exegesis.

description: Topological metals possess gapless band structures accompanied with nontrivial edge states. Topological metals are created from the topological insulators by adjusting the magnetic flux. Here we propose the time-reversal symmetry protected topological metal without employing the magnetic flux. Topological metallic phase presents although the Chern number vanishes. In the topologically nontrivial phase, three different cases in the metallic phase are distinguished from the band-touching and in-gap features of the topological edge states. These findings shed light on the time-reversal symmetric topological metals and greatly simplify the realization of topological metals.

description: The investigation of asteroids near the Sun is important for understanding the final evolutionary stage of primitive solar system objects. A near-Sun asteroid, (155140) 2005 UD, has orbital elements similar to those of (3200) Phaethon (the target asteroid for the JAXA's $DESTINY^+$ mission). We conducted photometric and polarimetric observations of 2005 UD and found that this asteroid exhibits a polarization phase curve similar to that of Phaethon over a wide range of observed solar phase angles ($ α= 20 - 105^\circ $) but different from those of (101955) Bennu and (162173) Ryugu (asteroids composed of hydrated carbonaceous materials). At a low phase angle ($α\lesssim 30^\circ$), the polarimetric properties of these near-Sun asteroids (2005 UD and Phaethon) are consistent with anhydrous carbonaceous chondrites, while the properties of Bennu are consistent with hydrous carbonaceous chondrites. We derived the geometric albedo, $ p_\mathrm{V} \sim 0.1 $ (in the range of 0.088-0.109); mean $ V $-band absolute magnitude, $ H_\mathrm{V} = 17.54 \pm 0.02 $; synodic rotational period, $ T_\mathrm{rot} = 5.2388 \pm 0.0022 $ hours (the two-peaked solution is assumed); and effective mean diameter, $ D_\mathrm{eff} = 1.32 \pm 0.06 $ km. At large phase angles ($ α\gtrsim 80^\circ$), the polarization phase curve are likely explained by the dominance of large grains and the paucity of small micron-sized grains. We conclude that the polarimetric similarity of these near-Sun asteroids can be attributed to the intense solar heating of carbonaceous materials around their perihelia, where large anhydrous particles with small porosity could be produced by sintering.

description: Solar-powered long-endurance unmanned aerial vehicles (UAVs) offer significant potential for various applications due to their extended flight endurance. However, optimizing the design of solar-powered UAVs to achieve maximum efficiency and performance remains a complex challenge. The main objective of this research is to explore the sensitivity of solar-powered UAV mass to different design variables and technological constraints. The study employs a conceptual design methodology, iterating through various design configurations while specific design variables within bounds of historical data. Key parameters, including aspect ratio, wing span, payload mass, power consumption, cruise altitude, and technological constraints such as solar panel efficiency and battery energy density, are systematically varied to analyze their impact on UAV mass. The study also considers the influence cloud cover on solar power generation. This parametric study's results divulge solar-powered UAV mass's sensitivity to these design variables and technological constraints. By identifying key factors influencing UAV mass, the study offers actionable insights for designers and engineers in aerospace industry. The findings contribute to advancing the understanding of solar-powered UAV technology and lay the groundwork for future research and development initiatives to enhance UAV performance and efficiency.

description: The wing of a fighter aircraft has various structural members which support aerodynamic and inertial loads, and transmit these loads to the fuselage. As a foremost step to evaluate the structural behaviour of the wing assembly, component contribution analysis is carried out. A finite element analysis of wing tulip of fighter aircraft isolated from the wing was performed under the design load case. Since aircraft wing is a statically indeterminate structure, reaction forces and moments at the supports depend upon the stiffness characteristics of the wing itself. In addition, stiffness of wing also affects the distribution of load and resulting deformation of the wing. These require that support structure of tulip isolated from the global wing model is represented by appropriate boundary conditions for the analysis. A comparative study for three boundary conditions (fixed support, nodal displacements and elastic support) was carried out to determine the representative boundary condition for the analysis of structural members isolated from the global model. It was found that elastic support represents the stiffness of the global model and is a more appropriate boundary condition for the analysis of local models which are isolated from a global model.

description: Ground-based observation at frequencies below 30 MHz is hindered by the ionosphere of the Earth and radio frequency interference. To map the sky at these low frequencies, we have proposed the Discovering the Sky at the Longest wavelength mission (DSL, also known as the "Hongmeng" mission, which means "Primordial Universe" in Chinese) concept, which employs a linear array of micro-satellites orbiting the Moon. Such an array can be deployed to the lunar orbit by a single rocket launch, and it can make interferometric observations achieving good angular resolutions despite the small size of the antennas. However, it differs from the conventional ground-based interferometer array or even the previous orbital interferometers in many aspects, new data-processing methods need to be developed. In this work, we make a series of simulations to assess the imaging quality and sensitivity of such an array. We start with an input sky model and a simple orbit model, generate mock interferometric visibilities, and then reconstruct the sky map. We consider various observational effects and practical issues, such as the system noise, antenna response, and Moon blockage. Based on the quality of the recovered image, we quantify the imaging capability of the array for different satellite numbers and array configurations. For the first time, we make practical estimates of the point source sensitivity for such a lunar orbit array, and predict the expected number of detectable sources for the mission. Depending on the radio source number distribution which is still very uncertain at these frequencies, the proposed mission can detect $10^2 \sim 10^4$ sources during its operation.

La tutela cautelare del diritto d'autore

description: La ricerca è dedicata all’individuazione e all’analisi delle misure cautelari poste a presidio del diritto d’autore. La materia della proprietà intellettuale è fra quelle nelle quali il tempo occorrente per far valere il diritto in via ordinaria comporta un pregiudizio irreparabile. Scopo dell’indagine è dunque quello di evidenziare come l’esperienza del contenzioso in materia di diritto d’autore abbia dato linfa sempre crescente al procedimento cautelare. In quest’ottica si deve considerare che la tendenziale stabilità delle misure cautelari anticipatorie rappresenta un primo passo, sia pure ancora insufficiente, verso uno svolgimento del processo connotato da celerità e speditezza, tale da garantire un’effettiva tutela giurisdizionale. La tutela cautelare diventa, dunque, la pietra milare per dare attuazione al principio di matrice chiovendiana per cui la durata del processo non deve andare a danno della parte che ha ragione, precludendo e vanificando l’attuazione del diritto. Nel corso dell’indagine si dà conto di come il legislatore non abbia individuato quali siano i provvedimenti anticipatori dotati di stabilità e abbia lasciato questo compito all’interprete. Il presente lavoro si impone anche di offrire qualche riflessione per individuare, nell’ambito della tutela cautelare del diritto d’autore, quali siano i provvedimenti cautelari idonei ad anticipare gli effetti della sentenza di merito.

description: As an important biomedical database, PubMed provides users with free access to abstracts of its documents. However, citations between these documents need to be collected from external data sources. Although previous studies have investigated the coverage of various data sources, the quality of citations is underexplored. In response, this study compares the coverage and citation quality of five freely available data sources on 30 million PubMed documents, including OpenCitations Index of CrossRef open DOI-to-DOI citations (COCI), Dimensions, Microsoft Academic Graph (MAG), National Institutes of Health Open Citation Collection (NIH-OCC), and Semantic Scholar Open Research Corpus (S2ORC). Three gold standards and five metrics are introduced to evaluate the correctness and completeness of citations. Our results indicate that Dimensions is the most comprehensive data source that provides references for 62.4% of PubMed documents, outperforming the official NIH-OCC dataset (56.7%). Over 90% of citation links in other data sources can also be found in Dimensions. The coverage of MAG, COCI, and S2ORC is 59.6%, 34.7%, and 23.5%, respectively. Regarding the citation quality, Dimensions and NIH-OCC achieve the best overall results. Almost all data sources have a precision higher than 90%, but their recall is much lower. All databases have better performances on recent publications than earlier ones. Meanwhile, the gaps between different data sources have diminished for the documents published in recent years. This study provides evidence for researchers to choose suitable PubMed citation sources, which is also helpful for evaluating the citation quality of free bibliographic databases.

description: Biometric methods based on iris images are believed to allow very high accuracy, and there has been an explosion of interest in iris biometrics in recent years. In this paper, we use the Scale Invariant Feature Transformation (SIFT) for recognition using iris images. Contrarily to traditional iris recognition systems, the SIFT approach does not rely on the transformation of the iris pattern to polar coordinates or on highly accurate segmentation, allowing less constrained image acquisition conditions. We extract characteristic SIFT feature points in scale space and perform matching based on the texture information around the feature points using the SIFT operator. Experiments are done using the BioSec multimodal database, which includes 3,200 iris images from 200 individuals acquired in two different sessions. We contribute with the analysis of the influence of different SIFT parameters on the recognition performance. We also show the complementarity between the SIFT approach and a popular matching approach based on transformation to polar coordinates and Log-Gabor wavelets. The combination of the two approaches achieves significantly better performance than either of the individual schemes, with a performance improvement of 24% in the Equal Error Rate.

description: In this contribution, the vulnerabilities of iris-based recognition systems to direct attacks are studied. A database of fake iris images has been created from real iris of the BioSec baseline database. Iris images are printed using a commercial printer and then, presented at the iris sensor. We use for our experiments a publicly available iris recognition system, which some modifications to improve the iris segmentation step. Based on results achieved on different operational scenarios, we show that the system is vulnerable to direct attacks, pointing out the importance of having countermeasures against this type of fraudulent actions.
