description: This report presents the results of the media scan and analysis task (T3.6) of the TechEthos project. This study was carried out between November 2021 and May 2022. It sought to gain insights on the media discourse on TechEthos’ three families of technologies: geoengineering, neurotechnology and digital extended reality. The media both reflect and shape public perceptions on technologies and, as such, give important indications of these perceptions. This study contributes to TechEthos’ analysis of public awareness and acceptance of the three families of technology (the focus of TechEthos WP3), through an exploration of media discourse. This task was led by Trilateral Research and carried out with the support of TechEthos’ partners and the science centers and museums associated with the project. The task explored the media discourse in 13 countries - it looked at online news outlets (excluding social media). This included ten EU countries: Austria, Czech Republic, France, Germany, Ireland, Italy, Netherlands, Romania, Spain, and Sweden and three non-EU countries: Serbia, UK, and USA. The study covered news stories published in 2020 and 2021. To scan and analyse the massive amount of data of interest to this analysis, we used state-of-the art computational tools to collect, clean and analyse the data. This made it possible to collect and analyse a large set of news stories which would not have been possible with traditional and manual techniques. However, it also presented some challenges, especially in relation to data access. For various reasons, it appeared that some key media outlets were missing from the datasets and that we were sometimes missing data for a few months in 2020 and 2021. It is thus difficult to assess the representativeness of the results of this study. That said, we believe that this study provides interesting snapshots on the media discourse in these countries. In addition, it contributes to methods for the analysis of media discourses through computational methods. This report presents the method used in the study in detail.

description: Ce travail se fonde sur le constat que la discipline du français constitue pour les apprentis employés de commerce la seule occasion, d’une part de se confronter à la culture, qui s’incarne de manière privilégiée dans la littérature, et d’autre part de questionner la société de manière critique et distanciée. Parmi les problématiques qu’il est alors possible de traiter, il nous semble capital d’aborder celle du genre, car elle constitue un aspect important de la réalité des élèves. Sur la base de ce bilan, nous posons la question suivante : comment permettre à des élèves de deuxième année de formation de commerce (FCE) de problématiser le fonctionnement et les usages des stéréotypes de genre, tout en dispensant un enseignement littéraire ? Notre réponse, sous forme de séquence d’enseignement, se base sur l’hypothèse selon laquelle le questionnement autour du genre et l’étude de la littérature doivent s’enrichir mutuellement. En effet, la littérature véhicule elle-même des stéréotypes, mais peut aussi les problématiser, et ainsi servir d’amorce pour une réflexion critique sur la manière dont sont culturellement construites les identités féminines et masculines. En retour, le travail sur la thématique du genre est propice à établir des rapprochements entre le contenu d’une œuvre et la manière dont les élèves pensent l’homme, la société, le monde ; ce qui peut contribuer à susciter chez ces derniers un intérêt nouveau pour la littérature. Nous proposons des activités qui convoquent diverses productions culturelles, et qui gravitent autour du roman de Noëlle Revaz, intitulé Rapport aux bêtes. La séquence poursuit trois objectifs : amener les élèves à problématiser le fonctionnement des stéréotypes dans la construction des identités féminines et masculines ; montrer que ces identités impliquent une hiérarchie dans les rapports entre hommes et femmes, où ces dernières sont dévalorisées ; permettre aux élèves de prendre conscience de l’intérêt de la littérature comme moteur de réflexion, pour se penser eux-mêmes, dans le rapport qu’ils entretiennent à l’autre.

D2.5 - Report on modelling of Non-linear Wind-wave interaction
Creators: name: Panjwani, Balram
Publisher: name: Zenodo
Year: 2022

description: For modeling non-linear wind-wave interaction, an Openfoam Solver "SOWFA (Simulator for Offshore Wind Farm Applications) " developed by NREL has been utilized. The short sea waves were modeled using a boundary layer model with an appropriate roughness factor. The swell effects were modeled by creating a computational domain consisting of predefined waves. The study showed that for modeling the short sea waves, the algebraic correlations (logarithmic wind velocity profiles) are sufficient.

description: We present parsec scale interferometric maps of HCN(1-0) and HCO$^{+}$(1-0) emission from dense gas in the star-forming region 30 Doradus, obtained using the Australia Telescope Compact Array. This extreme star-forming region, located in the Large Magellanic Cloud (LMC), is characterized by a very intense ultraviolet ionizing radiation field and sub-solar metallicity, both of which are expected to impact molecular cloud structure. We detect 13 bright, dense clumps within the 30 Doradus-10 giant molecular cloud. Some of the clumps are aligned along a filamentary structure with a characteristic spacing that is consistent with formation via the varicose fluid instability. Our analysis shows that the filament is gravitationally unstable and collapsing to form stars. There is a good correlation between HCO$^{+}$ emission in the filament and signatures of recent star formation activity including H$_{2}$O masers and young stellar objects (YSOs). YSOs seem to continue along the same direction of the filament toward the massive compact star cluster R136 in the southwest. We present detailed comparisons of clump properities (masses, linewidths, sizes) in 30Dor-10 to those in other star forming regions of the LMC (N159, N113, N105, N44). Our analysis shows that the 30Dor-10 clumps have similar mass but wider linewidths and similar HCN/HCO$^{+}$ (1-0) line ratios as clumps detected in other LMC star-forming regions. Our results suggest that the dense molecular gas clumps in the interior of 30Dor-10 are well-shielded against the intense ionizing field that is present in the 30Doradus region.

description: De nos jours, le burnout ou épuisement émotionnel est un phénomène fréquent. Il se compose de trois dimensions : l’épuisement émotionnel, le cynisme et la réduction de l’accomplissement personnel. Il touche toutes les professions. Les étudiants en général et les étudiants à l’enseignement en particulier ne font pas exception, mais jusqu’à présent, le domaine est peu connu, car peu d’études ont été menées sur cette population. Pourtant, le burnout de l’étudiant à l’enseignement peut représenter un danger pour lui-même et pour ses (futurs) élèves. En effet, lorsqu’un enseignant est en situation de burnout, il peut arriver qu’il adopte une posture cynique ou déshumanisante envers l’élève. Cette déshumanisation de l’élève est certes un mécanisme de défense pour l’enseignant, mais cela devient un danger pour l’élève, car une telle posture peut provoquer des attitudes violentes chez l’élève et augmenter ses difficultés. Dans le cadre du stage qu’ils effectuent lors de leur formation, les étudiants à l’enseignement sont régulièrement en contact avec les élèves, et ils le seront évidemment plus fréquemment une fois leur formation terminée. Etant donné que le burnout des enseignants peut débuter dès leur formation, le burnout des étudiants à l’enseignement peut être considéré comme un danger direct et indirect pour eux-mêmes et pour les élèves. Cette étude qualitative fait suite à une étude quantitative menée auprès d’étudiants à l’enseignement du canton de Vaud et a aussi pour objectif d’identifier les facteurs de risque et de protection du burnout pour améliorer la situation de l’étudiant et celle de ses élèves. Il ressort de cette étude que les stratégies de gestion de stress centrées sur les émotions et une utilisation d’une grande diversité de stratégies sont peut-être un facteur de risque du burnout. Il semblerait que cela ne soit pas le type de loisirs, mais plutôt l’interaction sociale qui a lieu pendant le loisir qui puisse être considérée comme facteur de protection du burnout. De plus, le fait de ressentir une plus grande intensité d’émotions agréables que désagréables serait aussi protecteur. Pour finir, le lien entre soutien social et burnout et le lien entre régulation des émotions et burnout sont difficiles à définir.

description: Cyanides, ranging from three carbon atoms to PAHs, and alkenyl compounds are abundant in the interstellar medium (ISM). Aminoacrylonitrile (3-Amino-2-propenenitrile, H$_{2}$N-CH=CH-CN), an alkenyl cyanide, thus represents a promising candidate for new interstellar detection. A comprehensive spectroscopic laboratory investigation of aminoacrylonitrile in its rotational ground vibrational state has been herein performed. The measurements carried out up to the THz regime made it possible to generate a precise set of reliable rest frequencies for its search in space up to sub-millimetre wavelengths. The $Z$-aminoacrylonitrile ($Z$-apn) isomer spectrum has been recorded employing a source-modulated sub-millimetre spectrometer, from 80 GHz to 1 THz. A combination of Doppler and sub-Doppler measurement regimes allowed to record 600 new lines. The collected data have enabled the characterisation of a set of spectroscopic parameters up to decic centrifugal distortion constants. The catalogue generated from the improved spectral data has been used for the search of $Z$-apn in the spectral survey of the G+0.693-0.027 molecular cloud located in the central molecular zone, in the proximity of the Galactic centre.

description: This report was developed as part of TechEthos, a project funded by the European Union’s Horizon 2020 Research and Innovation Programme. TechEthos aims to facilitate “ethics by design” by bringing ethical and societal values into the design and development of new and emerging technologies with a high socio-economic impact. The technology families selected for the project are climate engineering, neurotechnologies, and digital extended reality (XR). These three technology families present many significant legal issues that impact socio-economic equality and fundamental rights. This report explores and analyses relevant international and EU laws and policies for their relevance and applicability to the three technology families. Based on the analysis of the characteristics, applications and ethics and socio-economic impacts of these technologies, as emerged in previous phases of the TechEthos project, the report served different purposes: To review the legal domains and related obligations at international and EU levels. To identify potential implications for fundamental rights and principles of democracy and rule of law, considering both enhancements and interferences. To reflect on issues and challenges of existing legal frameworks to address current and future implications of the technologies.

description: In addition to the Evershed flow directed from the umbra towards the outer boundary of the sunspot, under special circumstances, a counter Evershed flow (CEF) in the opposite direction also occurs. We aim to characterize the proper motions and evolution of three CEFs observed by the Solar Optical Telescope onboard the Japanese Hinode spacecraft and the Helioseismic and Magnetic Imager onboard the Solar Dynamics Observatory. We use state-of-the-art inversions of the radiative transfer equation of polarized light applied to spectropolarimetric observations of the Fe I line pair around 630 nm. The three CEFs appeared within the penumbra. Two of the CEF structures, as part of their decay process, were found to move radially outwards through the penumbra parallel to the penumbral filaments with speeds, deduced from their proper motions, ranging between 65 and 117 m/s. In these two cases, a new spot appeared in the moat of the main sunspot after the CEFs reached the outer part of the penumbra. Meanwhile, the CEFs moved away from the umbra, and their magnetic field strengths decreased. The expulsion of these two CEFs seems to be related to the normal Evershed flow. The third CEF appeared to be dragged by the rotation of a satellite spot. Chromospheric brightenings were found to be associated with the CEFs, and those CEFs that reached the umbra-penumbra boundary showed enhanced chromospheric activity. The two CEFs, for which line-of-sight velocity maps were available during their formation phase, appear as intrusions into the penumbra. They may be associated with magnetic flux emergence.

description: With the continuous development of modern industry, environmental problems accompanied by heavy metal Pb(II) and organic dyes become increasingly apparent, and the development of associated detection/removal materials has important practical significance thus. In this work, a novel biomass (diphenolic acid and furfurylamine)-based, polyamide-sulfonate cross-linked polymer (PA-df-OBSC) was successfully constructed. Further characterization of PA-df-OBSC indicated that the chemical structure of PA-df-OBSC consists of multiple N/O/S-containing molecular fragments as amide, tertiary amine, carboxylic acid, sulfonate ester and sulfonate acid. Such structural characteristic endows PA-df-OBSC dual functional application prospect. PA-df-OBSC can be applied as an enrichment-type Pb(II) electrochemical probe due to its specific complexation for Pb(II). The modified glassy carbon electrode (GCE) with PA-df-OBSC as active modifier presented a wide detection range (0.1–30 μmol/L) and low detection limit (1.31 × 10−8 M) for Pb(II). Besides, PA-df-OBSC also showed selective adsorption for cationic dye methylene blue (MB), with the maximum adsorption capacity up to 521.72 mg/g.
On the Simultaneous Solution of Structural Membranes on all Level Sets within a Bulk Domain

description: A mechanical model and numerical method for structural membranes implied by all isosurfaces of a level-set function in a three-dimensional bulk domain are proposed. The mechanical model covers large displacements in the context of the finite strain theory and is formulated based on the tangential differential calculus. Alongside curved two-dimensional membranes embedded in three dimensions, also the simpler case of curved ropes (cables) in two-dimensional bulk domains is covered. The implicit geometries (shapes) are implied by the level sets and the boundaries of the structures are given by the intersection of the level sets with the boundary of the bulk domain. For the numerical analysis, the bulk domain is discretized using a background mesh composed by (higher-order) elements with the dimensionality of the embedding space. The elements are by no means aligned to the level sets, i.e., the geometries of the structures, which resembles a fictitious domain method, most importantly the Trace FEM. The proposed numerical method is a hybrid of the classical FEM and fictitious domain methods which may be labeled as "Bulk Trace FEM". Numerical studies confirm higher-order convergence rates and the potential for new material models with continuously embedded sub-structures in bulk domains.

description: Click chemistry has emerged as a versatile and robust polymerization technique for the construction of functional polymers. In this work, organocatalyst-mediated consecutive thiol-yne and thiol-ene click reactions were performed for the synthesis and modification of the electron-deficient poly(vinylene sulfide) (PVS) structure. PVS was prepared within an hour in the presence of 1,4-diazabicyclo[2.2.2] octane (DABCO) and in an anti-Markovnikov fashion, with a high molecular weight (Mn = 12.9 kDa) and high stereoregularity (88% E-isomer). Following various optimization studies using 1-propanethiol as the model thiol, the obtained PVS was modified with various thiols in chloroform for 10 min using 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as the catalyst, resulting in thioacetal main chain polymers. The scope of thiols used in the modification studies spans from alkyl and cycloalkyl to aromatic and allylic, and the polymers were obtained with varying efficiencies. Primary alkyl and aromatic thiols exhibited high efficiencies ranging from 87% to 100%. Similar high efficiencies were found for secondary mercaptans (70% and 92%); however, a very low efficiency (5%) was found for a tertiary mercaptan due to steric hindrance. It is believed the proposed indirect polythioacetal synthesis method holds the potential to be utilized in bio-related applications and material science.

description: It has long been known that luminous, ultra-steep spectrum radio sources are preferentially associated with massive galaxies at high redshifts. Here we describe a pilot project directed at such objects, to demonstrate the feasibility and importance of using LOFAR to study the most distant forming massive galaxies and protoclusters. We have successfully imaged four high-redshift ($z>2$) high-luminosity radio galaxies with sub-arcsecond resolution, at 144 MHz, using the International LOFAR Telescope (ILT). Our targets were 4C 41.17 ($z=3.8$), the "Anthill", B2 0902+34 ($z=3.4$), 4C 34.34 ($z=2.4$) and 4C 43.15 ($z=2.5$). Their low-frequency morphologies and the spatial distributions of their low-frequency spectral indices have been mapped, and compared with available optical, infrared, and X-ray images. Both for the Anthill at $z = 3.8$ and B2 0902+34 at $z=3.4$, the location of the steepest radio emission coincides with the Ly$α$ emitting ionized gas halo. Our pilot project demonstrates that, because of its outstanding sensitivity and high angular resolution at low frequencies, the ILT is a unique facility for studying the co-evolution and interaction of massive galaxies, galaxy clusters, and supermassive black holes in the early Universe.

description: L’anglais est une langue vivante qui laisse une grande place à la créativité didactique et pédagogique. Les nouveaux médias sont amenés à être de plus en plus présents en classe, parmi lesquels le film tient une place privilégiée. On constate, cependant, que même si le film est déjà utilisé à des fins didactiques d’apprentissage, il ne l’est pas encore à grande échelle : seul 6% des enseignants questionnés disent utiliser le film régulièrement. En effet, le film de cinéma est un produit largement consommé comme divertissement, mais son utilisation est encore trop souvent réduite à un statu secondaire d’exemplification ou de récompense. Pourtant, le film est un support à l’enseignement particulièrement riche sur les plans de la langue et du contenu et il est de fait sous-exploité. C’est pourquoi nous pensons qu’il est essentiel de valoriser ce médium et l’étendue de son potentiel d’exploitation et d’exploration didactique. Notre travail tente de répondre à la question de l’apport du film dans l’enseignement de l’anglais au secondaire II. Nous souhaitons montrons qu’une approche méthodique permet de l’utiliser pleinement, tant pour l’apprentissage de la langue que pour la réflexion intellectuelle. Dans cette optique, nous examinons en premier lieu comment la didactique des langues- cultures étrangères justifie l’usage du film comme support à l’enseignement. Nous expliquons comment il s’insère dans une approche communicative de la langue et quels sont ses apports concrets en tant que matériel authentique. Puis, nous présentons plus en détails les avantages de l’utilisation du film comme ressource linguistique et base au développement de la notion d’interculturalité. La troisième partie s’attache à montrer pourquoi une initiation à l’analyse de film est pertinente dans notre approche et comment elle permet d’aller plus loin en liant l’apprentissage de la langue à la construction d’un regard critique. Finalement, nous évoquons les limites de cette approche et les précautions à prendre lors de la préparation de séquences d’enseignement basées sur le film. Nous terminons sur une réflexion autour de la gestion des émotions générées par film et invitons à garder un regard critique par rapport au film en tant que produit du consumérisme culturel.

description: A late Iron Age to early Roman rectilinear enclosure, boundary ditch and field system produced pottery and animal bone suggesting that the settlement was of average status. Evidence for craft production included two triangular loomweights. The postholes of a small timber hall and other probable timber structures have been radiocarbon dated to the middle Anglo-Saxon period (mid to late 7th to 8thbcenturies AD). The settlement had been abandoned before the late Saxon period, but it may have been a precursor to medieval settlement at nearby Thorpe End.

description: Ce travail se propose d'étudier la transition entre le secondaire I et II et de comprendre en quoi les rituels peuvent favoriser le passage de l'un à l'autre. Du point de vue de l'élève, cette transformation peut générer une certaine insécurité que le rituel, utilisé à bon escient, peut fortement réduire. Or l'enseignant, dans une logique de bienveillance à l'égard de ses élèves, doit se poser la question de son rôle dans cette transition. Pour le comprendre, nous avons décidé d'organiser ce travail en deux parties qui dialoguent l'une avec l'autre. Dans un premier temps, il nous a semblé important de définir, à l'aide des études scientifiques en la matière, ce que les concepts de transition et de rituel recouvraient. Dans un deuxième temps, nous avons souhaité mener une réflexion sur notre propre pratique d'enseignement en croisant nos expériences dans nos classes avec les éléments théoriques dégagés dans la première partie. Enfin, en guise de conclusion, nous avons expliqué en quoi l'utilisation efficace du rituel dans un cadre scolaire peut à la fois renforcer l'unité du groupe classe et approfondir la relation pédagogique entre l'enseignant et les élèves. Ce travail de réflexion invite donc l'enseignant à considérer le rituel comme un outil efficace non seulement lors du grand moment de transition qu'est la rentrée mais aussi dans sa pratique quotidienne. Néanmoins, à force d'être employé, l'efficacité du rituel risque de diminuer. Pour que le rituel ne se transforme pas en habitude stérile, le fameux "on a toujours fait comme ça", il est important de l'investir d'une valeur et d'un sens symbolique. L'enseignant, maître de cérémonie du rituel, doit lui-même l'incarner. Il doit comprendre en quoi ce dernier est utile. Nous touchons ici au but fondamental de ce travail qui est de proposer du sens au rituel.

description: Previous observations of the middle-aged $γ$-ray, X-ray, and radio pulsar B1055-52 indicated some peculiarities, such as a suspected changing of the X-ray flux and spectral parameters, a large excess of the alleged thermal component of the ultraviolet (UV) spectrum over the Rayleigh-Jeans extension of the X-ray thermal spectrum, and a possible double break in the nonthermal spectral component between the optical and X-ray bands. We observed PSR B1055-52 with the XMM-Newton observatory in X-rays and the Hubble Space Telescope in near-infrared (NIR). The analysis of the XMM-Newton observations does not support the notion of long-term changes in the X-ray flux and broad-band X-ray spectrum of the pulsar. Using an observing mode less affected by background noise than the previous XMM-Newton observations, we constrain the power-law (PL) spectral index as $α_X=-0.57^{+0.26}_{-0.25} $ ($F_ν \propto ν^α$) in the energy band 3-10 keV. From the NIR-optical data we obtain a PL slope $α_O= -0.24 \pm 0.10$ for the color index $E(B-V)=0.03$ mag. The slopes and fluxes of the NIR-optical and X-ray nonthermal spectra suggest that the NIR through X-ray emission can be described by the same PL and is generated by the same mechanism, unlike the pulsar's $γ$-ray emission. The excess of the UV thermal component over the extension of the X-ray thermal component became smaller but did not disappear, indicating a non-uniformity of the bulk surface temperature. The NIR data also enable us to accurately measure the proper motion with values $μ_α=47.5\pm 0.7\,{\rm mas\,yr}^{-1}$ and $μ_δ= -8.7 \pm 0.7 \,{\rm mas\,yr}^{-1}$.

description: We report on the \nustar{} observation of the newly discovered neutron star X-ray binary Swift~J1858.6-0814 taken on 23rd March 2019. The light curve of the source exhibits several large flares during some time intervals of this observation. The source is softer in the high-intensity interval where the large flaring activity mainly occurs. We perform time-resolved spectroscopy on the source by extracting spectra for two different intensity intervals. The source was observed with a $3-79 \kev{}$ luminosity of $\sim 9.68\times 10^{36}$ ergs/s and $\sim 4.78\times 10^{36}$ ergs/s for high and low-intensity interval, respectively assuming a distance of $15$ kpc. We find a large value of the absorbing column density ($\rm{N_{H}}\sim 1.1\times 10^{23}$ cm$^{-2}$), and it appears to be uncorrelated with the observed flux of the source. Each spectrum shows evidence of Fe K$α$ emission in the $5-7$\kev{} energy band, an absorption edge around $\sim 7-8$\kev{}, and a broad Compton hump above $15$\kev{}, indicating the presence of a reflection spectrum. The observed features are well explained by the contribution of a relativistic reflection model and a partially covering absorption model. From the best-fit spectral model, we found an inner disc radius to be $4.87_{-0.96}^{+1.63}\;R_{ISCO}$ (for the high-intensity interval) and $5.68_{-2.78}^{+9.54}\;R_{ISCO}$ (for the low-intensity interval), indicating a significant disc truncation. The disk inclination is found to be relatively low, $i< 33^{0}$. We further place an upper limit on this source's magnetic field strength considering the disc is truncated at the magnetospheric radius.

description: New magnetic yolk-shell mesoporous silica nanoparticles (Fe3O4@V-mSiO2-PNVCL) were prepared by grafting temperature-sensitive amino-terminated poly (N-vinylcaprolactam) (PNVCL-NH2) on the surface of aldehyde-functionalized magnetic mesoporous silica nanoparticles (Fe3O4@V-mSiO2-CHO) through a Schiff base reaction. Various characterizations were used to confirm the structures, and the drug loading and release behaviors were studied. The drug loading was achieved as PNVCL stretched at room temperature and the drug loading content was up to 54.7% due to the large cavities. The encapsulation of drug from leakage in the blood environment was realized as PNVCL collapsed at physiological temperature. The fracture of pH-liable imine bonds in a slightly acidic tumor environment triggered the burst release of cargo. The Fe3O4@V-mSiO2-PNVCL showed super paramagnetic behavior (21.01 emu∙g−1) which could achieve magnetic targeting. The MTT assay confirmed that the nanoparticles exhibited low cytotoxicity. Furthermore, the cellular uptake experiments indicated that DOX-loaded nanoparticles were successfully internalized into cancer cells. Therefore, the composite nanoparticles are ideal choices for drug carriers.
Is establishment of an independent national human rights institution possible in Poland? : legal and operational analysis of the possibility and means of implementation of such a body in Poland

description: Second semester University: Lund University
description: This dissertation concerns the possibility of establishment of an independent National Human Rights Institution (NHRI) in Poland and measures necessary to implement such an institution. For the last 50 years, the NHRIs have become important institutional tools for promotion and protection of international human rights law on national level. The thesis proves that the role of NHRIs has been strengthened during the last 20 years after adoption of the UN soft law Paris Principles in 1993, which established international minimum standards concerning the status and functioning of national institutions and provided guidelines for States in terms of the independence of NHRIs. Therefore, the Paris Principles’ criteria of independence, together with binding functional conditions of independence set forth in the EU Directives, have been chosen as tools of legal and operational analysis and comparison of the level of independence of the Polish NHRIs in order to provide the answer to the main question of the thesis . As a result of this analysis, the Commissioner for Civil Rights Protection (Polish Ombudsman) has proven the only national institution which complies with the Paris Principles in terms of independence. However, it cannot be recognized as an NHRI fully in line with the Paris Principles, due to limitation of its mandate, which is not ‘as broad as possible’ in terms of promotion and protection of human rights. Moreover, the Commissioner does not fulfill the most important ‘functioning’ condition of independence of the Directives: providing legal assistance to victims of discrimination. Therefore, the thesis presents the possible solutions and recommendations on changes necessary to establish NHRI in Poland, which would be fully in line both with the independence provisions of the Paris Principles and the Directives. The dissertation also proves lack of harmonisation of standards of ‘independence’ of NHRI, which can create problems for states such as Poland with double, international and regional, obligations in this area. The criteria of independence of NHRIs that are provided in the Directives are entirely different than those in the Paris Principles. Therefore, the thesis stresses the necessity of strengthening the ‘independence’ provisions in the EU law to be in line with the Paris Principles.
$\mathcal{PT}$-symmetric microring laser-absorber

description: The lasing and coherent perfect absorption (CPA) properties of $\mathcal{PT}$-symmetric microrings with mixed index and gain gratings, externally coupled to a bus waveguide, are theoretically investigated. For a complex grating at the $\mathcal{PT}$ symmetry breaking point, perfect unidirectional (either clockwise or counterclockwise) laser emission can be realized, however the grating does not discriminate longitudinal modes and CPA can not be simultaneously achieved. Above the grating $\mathcal{PT}$ symmetry breaking point, single mode emission and simultaneous CPA can be obtained, with unbalanced and controllable excitation of clockwise and counterclockwise modes in the ring.

Is the new citation-rank approach P100' in bibliometrics really new?
Creators: name: Schreiber, Michael
Publisher: name: arXiv
Year: 2014
Subjects: subject: Digital Libraries (cs.DL)
subject: FOS: Computer and information sciences

description: The percentile-based rating scale P100 describes the citation impact in terms of the distribution of unique citation values. This approach has recently been refined by considering also the frequency of papers with the same citation counts. Here I compare the resulting P100' with P100 for an empirical dataset and a simple fictitious model dataset. It is shown that P100' is not much different from standard percentile-based ratings in terms of citation frequencies. A new indicator P100'' is introduced.

Berry Phase, Lorentz Covariance, and Anomalous Velocity for Dirac and Weyl Particles

description: We consider the relation between spin and the Berry-phase contribution to the anomalous velocity of massive and massless Dirac particles. We extend the Berry connection that depends only on the spatial components of the particle momentum to one that depends on the the space and time components in a covariant manner. We show that this covariant Berry connection captures the Thomas-precession part of the Bargmann-Michel-Telegdi spin evolution, and contrast it with the traditional (unitary, but not naturally covariant) Berry connection that describes spin-orbit coupling. We then consider how the covariant connection enters the classical relativistic dynamics of spinning particles due to Mathisson, Papapetrou and Dixon. We discuss the problems that arise with Lorentz covariance in the massless case, and trace them mathematically to a failure of the Wigner-translation part of the massless-particle little group to be an exact gauge symmetry in the presence of interactions, and physically to the fact that the measured position of a massless spinning particle is necessarily observer dependent.

description: Au travers de ce travail de recherche, nous avons cherché à nous questionner au sujet des attentes émanant de la part des gymnasiens face à une option fitness et de les comparer aux finalités d’enseignement que les enseignants d’EPS ont lorsqu’ils donnent celle-ci. Après la lecture de différentes recherches en sociologie, nous avons établi les hypothèses de base suivantes : 1) Les élèves cherchent, au travers de cette activité, une modification corporelle amenant, pour les garçons, un gain de masse musculaire et, pour les filles, la sculpture d’un corps « parfait ». 2) L’enseignant cherche avant tout à donner le gout aux élèves et les connaissances de bases permettant la pratique du fitness de manière autonome et avec plaisir en dehors des murs du gymnase. Découlant de ces hypothèses, la question de la sociabilisation à l’âge de l’adolescence ainsi que la notion de la représentation ont également été développées. Nous avons aussi eu la volonté de nous questionner sur la notion de représentation corporelle ainsi que la manière dont cette dernière est véhiculée auprès du jeune public. L’analyse de nos résultats a permis de mettre en exergue le fait que les hypothèses de bases sont vérifiées bien que l’échantillon interrogé soit restreint. Afin de permettre un constat réutilisable dans l’enseignement, les différences de points de vue entre élèves et enseignants d’éducation physique sont également abordées. Nous avons essayé de proposer un travail pouvant servir de support lors d’un éventuel approfondissement durant la suite de notre carrière professionnelle.

description: In this paper, the generalized fractional operators involving Appell's function $F_3$ in the kernel due to Marichev-Saigo-Maeda are applied to the generalized $K$-Wright function. These fractional operators when applied to power multipliers of the generalized $K$-Wright function ${}_{p}Ψ^k_q$ yields a higher ordered generalized $K$-Wright function, namely, ${}_{p+3}Ψ^k_{q+3}$. The Caputo-type modification of Marichev-Saigo-Maeda fractional differentiation is introduced and the corresponding assertions for Saigo and Erdélyi-Kober fractional operators are also presented. The results derived in this paper generalize several recent results in the theory of special functions.

Late Saxon burials at All Saints Church, Little Billing, Northampton
Creators: name: Chinnock, Chris

description: Northamptonshire Archaeology, 39, 127-134
description: Archaeological excavation was undertaken at All Saints Church, Little Billing, Northampton, on the footprint of a proposed extension and along associated service trenches to the north of the church. Many of the burials encountered relate to the late medieval and post-medieval usage of the graveyard. However, two burials had stones placed around the head, an early medieval burial practice that is likely to pre-date the Norman Conquest. The deepest burials, beyond the proposed foundations of the extension, were left in situ.
A NICER View on the 2020 Magnetar-Like Outburst of PSR J1846-0258

description: We report on our monitoring of the strong-field magnetar-like pulsar PSR J1846-0258 with the Neutron Star Interior Composition Explorer (NICER) and the timing and spectral evolution during its outburst in August 2020. Phase-coherent timing solutions were maintained from March 2017 through November 2021, including a coherent solution throughout the outburst. We detected a large spin-up glitch of magnitude Δν/ν= 3 X 10^{-6} at the start of the outburst and observed an increase in pulsed flux that reached a factor of more than 10 times the quiescent level, a behavior similar to that of the 2006 outburst. Our monitoring observations in June and July 2020 indicate that the flux was rising prior to the SWIFT announcement of the outburst on August 1, 2020. We also observed several sharp rises in the pulsed flux following the outburst and the flux reached quiescent level by November 2020. The pulse profile was observed to change shape during the outburst, returning to the pre-outburst shape by 2021. Spectral analysis of the pulsed emission of NICER data shows that the flux increases result entirely from a new black body component that gradually fades away while the power-law remains nearly constant at its quiescent level throughout the outburst. Joint spectral analysis of NICER and simultaneous NuSTAR data confirms this picture. We discuss the interpretation of the magnetar-like outburst and origin of the transient thermal component in the context of both a pulsar-like and a magnetar-like model.
