description: H τεχνητή νοημοσύνη συνιστά μία από τις μεγαλύτερες τάσεις των τελευταίων ετών, αν και η εμφάνισή της μετρά αρκετές δεκαετίες. Σύμφωνα με τη μελέτη της Boston Consulting Group (2020) η ΤΝ ορίζεται ως «οι τεχνολογίες εκείνες οι οποίες μπορούν να παρουσιάσουν και να ενισχύσουν την ανθρώπινη συμπεριφορά εξαιτίας της ικανότητάς τους να αναλύουν το περιβάλλον τους και να επιτυγχάνουν συγκεκριμένους στόχους. Έτσι γίνεται σαφές πως η ΤΝ προσφέρει τεράστιες προοπτικές ανάπτυξης και οφέλη, προσδίδοντας αξία στις επιχειρήσεις». Η παρούσα εργασία αποτελεί προϊόν βιβλιογραφικής έρευνας, παρουσιάζοντας επίσης 2 μελέτες περίπτωσης, της Amazon και της Facebook. Στόχος αυτής της διπλωματικής εργασίας είναι να γίνει κατανοητό τι είναι η τεχνητή νοημοσύνη, πώς εφαρμόζεται στην καθημερινότητα και πώς εταιρίες κολοσσοί όπως η Amazon και η Facebook αξιοποιούν στο έπακρο τα οφέλη που τους προσφέρει για να μεγιστοποιήσουν τα κέρδη τους απ’ τη μία, αλλά και να ανταποκριθούν στη νέα τεχνολογική πραγματικότητα καινοτομώντας και συνάμα διατηρώντας την ηγετική θέση τους στον κλάδο τους. Επίσης, θα αναφερθούν εταιρίες που χρησιμοποιούν ΤΝ στην Ελλάδα, χώρα η οποία αποτελεί πόλο έλξης μεγάλων εταιριών τεχνολογίας τα τελευταία χρόνια, με πρόσφατο παράδειγμα το Digital Hub της Pfizer στη Θεσσαλονίκη. Θα γίνει επίσης προσπάθεια να εξαχθούν συμπεράσματα όχι μόνο για τις θετικές συνέπειες της χρήσης και εφαρμογής της ΤΝ, αλλά και για τα πιθανά αρνητικά αποτελέσματα που επιφέρει, όπως η αντικατάσταση κάποιων διεκπεραιωτικών θέσεων εργασίας από εφαρμογές ΤΝ, η απώλεια της ιδιωτικότητας και η έλλειψη του ανθρώπινου ελέγχου στα αυτοματοποιημένα συστήματα και στα ρομπότ. Λαμβάνοντας υπόψιν τα παραπάνω δεδομένα, καθίσταται επιτακτική ανάγκη η δημιουργία ενός κώδικα Ηθικής της ΤΝ, ο οποίος θα στοχεύει στη διασφάλιση μιας κοινωνικά ηθικής, διαφανούς και λελογισμένης χρήσης των τεχνολογιών της ΤΝ. Παρέχοντας ξεκάθαρους κανόνες, ο κώδικας δεοντολογίας της ΤΝ θα επιτρέψει στις επιχειρήσεις αλλά και στα κράτη να καινοτομήσουν αλλά και να συνειδητοποιήσουν τη μετασχηματιστική δυναμική της ΤΝ στο νέο ψηφιακό κόσμο.

description: Over the last 8 years, the transformation process with structural changes and the worsening of production technology in the Bulgarian dairy sector has led to a dramatic reduction of milk quality in Bulgaria. The improvement of the raw milk quality and the harmonisation of Bulgarian standards with EU milk quality standards is therefore on of the major conditions for the prospective integration of Bulgarian into the EU as well as for increasing the competitiveness of the Bulgarian dairy sector. This discussion paper presents the results of an in-depth analysis of the Bulgarian agriculture with special emphasis on milk production. The investigation aims to identify the basic problems of Bulgarian milk production, the main differences between the Bulgarian and the EU quality regulations for raw milk, and future necessary alterations in Bulgarian milk production farms with regard to the quality requirements of the European Union. The analysis' results show the causes for the development of the Bulgarian dairy sector in the transitional period. The comparison of the quality standards for raw milk emphasis the urgent need to adjust the Bulgarian system, especially regarding the number of control parameters and quality grades, the level of requirements for the hygienic quality of raw milk and the lack of a functioning pricing system based on the classification of raw milk. With respect to the improvement of raw milk quality and thus of economic results of Bulgarian dairy farms, the most urgent improvements are needed in the area of forage production, hygienic and housing conditions of animals as well as milking and feeding technology.

description: The Central and Eastern European Countries Agricultural Simulation Model (CEEC-ASIM) has been developed at IAMO. It is a partial equilibrium model for the agricultural sectors of 14 countries including demand of domestic consumers and is designed to analyse the impacts of agricultural policies on important target variables like producer and consumer prices, supply and input demand of agriculture, food demand, net trade and welfare. Particular efforts were undertaken to implement also the policy instruments of the Common Agricultural Policy of the European Union. These besides the market price support measures also include the different forms of domestic support as for example area payments and beef premiums. Also the set-aside obligations and production quotas can be taken into account. This discussion paper serves as a model documentation and describes the structure of the model along with the basic modelling assumptions. The model is essentially based on neoclassical theory. The main hypotheses are perfect markets, profit maximisation of producers and utility maximisation of consumers.

description: Boileau and Rudolph called a link $L$ in the $3$-sphere a $\bf C$-boundary if it can be realized as the intersection of an algebraic curve $A$ in $\bf C^2$ with the boundary of a smooth embedded $4$-ball $B$. They showed that some links are not $\bf C$-boundaries. We say that $L$ is a strong $\bf C$-boundary if $A\setminus B$ is connected. In particular, all quasipositive links are strong $\bf C$-boundaries. In this paper we give examples of non-quasipositive strong $\bf C$-boundaries and non-strong $\bf C$-boundaries. We give a complete classification of (strong) $\bf C$-boundaries with at most 5 crossings.

description: Over the last 7 years, the transformation process has led to drastic changes in the structure of the Bulgarian agricultural sector, and especially to a dramatic fall in milk production. Hence results the great importance of studies that analyse the general conditions of the agrarian sector as well as the economic situation of agricultural enterprises. This discussion paper presents the results of a study of the economic situation of milk production farms, which was carried out in the oblast Burgas, in the south east of Bulgaria. The aim of the investigation was the detailed analysis of the situation of Bulgarian milk production enterprises with respect to their production technologies and economic results. In addition, the comparative advantages and disadvantages of milk production in Bulgaria are discussed using a production costs comparison of Bulgarian and German milk production enterprises. The results show firstly the low level of Bulgarian milk production, and secondly the existing differences between the types of production equipment used by various legal forms of enterprises. The impact this has on the level of production costs and on the factor productivities is also pointed out in the paper. The comparison with German enterprises makes clear that the Bulgarian farms analysed have higher costs for forages and a lower labour productivity. These disadvantages will be partly compensated by the low level of labour costs, as well as by investments in the Bulgarian enterprises.

description: We have distributed entangled photons directly through the atmosphere to a receiver station 7.8 km away over the city of Vienna, Austria at night. Detection of one photon from our entangled pairs constitutes a triggered single photon source from the sender. With no direct time-stable connection, the two stations found coincidence counts in the detection events by calculating the cross-correlation of locally-recorded time stamps shared over a public internet channel. For this experiment, our quantum channel was maintained for a total of 40 minutes during which time a coincidence lock found approximately 60000 coincident detection events. The polarization correlations in those events yielded a Bell parameter, S=2.27/pm0.019, which violates the CHSH-Bell inequality by 14 standard deviations. This result is promising for entanglement-based free-space quantum communication in high-density urban areas. It is also encouraging for optical quantum communication between ground stations and satellites since the length of our free-space link exceeds the atmospheric equivalent.

description: Phycobilisomes present in cyanobacteria are photosynthetic macromolecular protein complexes that are categorized into three types - phycoerythrins (high energy), phycocyanin (intermediate energy) and allophycocyanin (low energy). Structurally, they consist of α and β protein subunits and open chain tetrapyrrole prosthetic group (bilin chromophore), known for its antioxidant properties and therapeutic potential against a variety of physiological ailments. Phycoerythrins (C-PE) were purified from cyanobacterial strains Phormidium sp. A27DM and Halomicronema sp. A32DM and their respective apoptotic potentials were assessed on A549 human lung carcinoma cells. Both strains of cyanobacteria were cultured and the C-PE from each strain was extracted, quantified and characterized. C-PE accounted for a dose dependent decrement in cell viability, mitochondrial membrane potential and an increment in lactate dehydrogenase release. Higher doses of C-PE (of both strains) accounted for loss of cell viability and nuclear pycnosis. These findings were further substantiated with flow cytometry that revealed a cell arrest at G0/G1 phase and a high percentage of cells undergoing apoptosis following C-PE treatment. These results confirm the efficacy of C-PE from Phormidium sp. or Halomicronema sp. in triggering apoptotic cell death. This study is the first to report on apoptotic property of C-PE against A549 human lung carcinoma cells and warrants further studies to establish its anti-cancer potential.

À corp(u)s perdus : corporéité et spatialité dans le théâtre de Bernard-Marie Koltès et d’Hélène Cixous
Creators: name: Mounsef, Donia

description: This thesis deals with the representation of the body and space in the theatre of Bernard-Marie Koltes and Helene Cixous. From the theoretical point of view, it looks at transition in French theatre from a modern to a postmodern predicament, from a discursive to a corporeal theatre. It then looks at the ways postmodern culture maps, configures, disciplines, and violates the body, particularly through the relationship of the new textuality to its stage manifestations. Textually, it analizes three plays by each playwright. The juxtaposition of the works of Koltes and Cixous allows for an in depth look at the theatre of the 1970's and 80's in France, a period marked by theatrical decentralisation and experimentation. Both favoured a strong tie to theatre practice while developing a close relationship with a theatre director: Patrice Chereau, in the case of Koltes, and Ariane Mnouchkine, in the case of Cixous. Aside from looking at the relationship with theatre practitioners, this thesis examines a number of aesthetic and political affinities which bring Koltes and Cixous together, such as redefining a postmodern mythology and a political role for theatre. Unlike many postmodernist theatre practices that try to evade political commitment, both Cixous and Koltes are preoccupied with the resistance to a nihilistic discourse, and propose an evolving and corporeal stage presence inscribed in a pluralistic space of representation. For Koltes, the body on the stage resists symbolic categorization in Combat de negre et de chiens (1979), it then becomes related to spatial reality outside language in Quai ouest (1985), and finally the corporeal body is culturally and ideologically mapped in Le Retour au desert (1988). This triple dimension is also reflected in the work of Cixous, for whom the theatre is a space of feminist praxis. First, the space of representation, through the subversive performativity of the body, questions the premises of the psychoanalytic gaze in Portrait de Dora (1976), then classical mythology is rewritten to disrupt patriarcal discourse in Le Nom d'Oedipe: chant du corps interdit (1978), and a post-colonial role for theatre is redefined in order to question the historical subject in L'Indiade ou l'lnde de leurs reves (1987). Finally, this thesis looks at the ways both Koltes and Cixous join in with postmodernism in declaring the impossibility of grand-narrative, while trying to show how identity cannot be based on essentialist categories of race, gender, ethnicity, or sexual orientation, but on the performance of all these various categories as they intersect in the performing body.

description: Controlling the optical response of a medium through suitably tuned coherent electromagnetic fields is highly relevant in a number of potential applications, from all-optical modulators to optical storage devices. In particular, electromagnetically induced transparency (EIT) is an established phenomenon in which destructive quantum interference creates a transparency window over a narrow spectral range around an absorption line, which, in turn, allows to slow and ultimately stop light due to the anomalous refractive index dispersion. Here we report on the observation of a new form of either induced transparency or amplification of a weak probe beam in a strongly driven silicon photonic crystal resonator at room temperature. The effect is based on the oscillating temperature field induced in a nonlinear optical cavity, and it reproduces many of the key features of EIT while being independent of either atomic or mechanical resonances. Such thermo-optically induced transparency (TOIT) will allow a versatile implementation of EIT-analogues in an integrated photonic platform, at almost arbitrary wavelength of interest, room temperature and in a practical, low cost and scalable system.

description: Under proper growth conditions, ordered and uniform Mn nanodots were fabricated on the Si(111)-7x7 surface without the presence of a wetting layer. Furthermore, the Mn nanodots deposited onto the elevated substrates were observed to occupy preferentially on the faulted half unit cells (FHUCs) of the Si(111)-7x7 surface. This phenomenon implies that the Mn dots adsorbed on the FHUCs is more stable than those adsorbed on the unfaulted half unit cells (UFHUCs). Within the framework of quasiequilibrium thermodynamics, the energy difference between adsorption on the UFHUCs and the FHUCs was estimated to be 0.05eV. The intrinsic attractive potential wells on the FHUCs effectively trap the outdiffusion of Mn atoms, and consequently result in a preferential arrangement of islands with well-defined sizes.

description: The discussion paper presents the results of an investigation on the taxation in Russian agroholdings. With consideration of the German legal situation, the terms "holding-company", "agricultural holding-company", and "agricultural-industry holding-company" are defined. Following the elements of tax planning by the Russian enterprises as well as the most important taxes in Russia are explained. It is considered that the Russian Federation has introduced a standardized agricultural tax at 2004-01-01 which does not apply however to enterprises which have branches and/or agencies. Among the mentioned methods the method from KADUSCHIN and MICHAILOVA reflects the smallest difference between calculated and real taxes. Further sections deal with questions of the tax adjustment in connection with transfer prices (agreement prices) and the price strategy in the enterprise groups controlled by the holding (internal prices) with the goal of the tax saving. Finally economic and social consequences of different transfer price systems are discussed. ZUSAMMENFASSUNG Das Discussion Paper beinhaltet Erkenntnisse zur Besteuerung russischer Agrar-Holdings in Russland. Eingangs werden ausgehend von der deutschen Rechtslage die Begriffe "Holding", "Agrar-Holding" und "Agrar-Industrie-Holding" definiert. Nachfolgend werden Elemente der Steuerplanung durch die russischen Unternehmen sowie die wichtigsten Steuern in Russland erläutert, wobei auf die Gesetzgebung für Unternehmen, die in ihrem Wesen Holdings entsprechen, verwiesen wird. Neu ist seit dem 01.01.2004 die einheitliche Landwirtschaftssteuer. Sie gilt jedoch nicht für Unternehmen, die Filialen und/oder Vertretungen haben. Von den Methoden zur Schätzung der Steuerbelastung der Unternehmen spiegelt die Methode nach KADUSCHIN und MICHAJLOVA die Realität am besten wider. Weitere Abschnitte befassen sich mit Fragen der Steuerregulierung im Zusammenhang mit Transferpreisen (Vereinbarungspreisen) und der Preispolitik in der durch die Holding beherrschten Gruppe (interne Preise) mit dem Ziel der Steuerersparnis. Abschließend wird auf wirtschaftliche und soziale Konsequenzen unterschiedlicher Transferpreissysteme aufmerksam gemacht.
Agricultural policies and farm structures - Agent-based modelling and application to EU-policy reform

Subjects: Agricultural and Food Policy

description: The development of competitive and efficient agricultural structures has been one of the central goals of agricultural policy making in addition to ensuring a fair standard of living for farmers. To achieve these goals, the agricultural sector in most industrialised nations has long been the subject of government interven-tions. However, many agricultural policies have worked counteractively to these goals by creating distortions in the use of resources. Against this background, the emergence of new and innovative modelling methods such as agent-based models, in addition to ever-increasing computing capacities has offered new possibilities to model adjustment reactions and to quantify the impact of agri-cultural policies. This thesis takes up these new methodologies and applies them to the modelling and evaluation of agricultural policy impacts on regional structural change in Baden-Württemberg. The thesis contributes to a deeper understanding of struc-tural change dynamics and factors causing structural change. The starting point of the analysis is the hypothesis that Hohenlohe's agricultural structure displays structural inefficiencies and that structural adjustment in the past has been im-peded by existing agricultural policies. Based on these assumptions, it is studied whether and to what extent policy changes can facilitate structural adjustment towards a more efficient and competitive agricultural structure.

description: Es ist seit langem bekannt, dass das Wetter den Hauptunsicherheitsfaktor in der pflanzlichen Produktion darstellt. Seit einiger Zeit wird der Einsatz von Wetterderivaten zur Absicherung gegen wetterbedingte Ertragsschwankungen diskutiert. In diesem Beitrag wird am Beispiel ei-nes getreideproduzierenden Betriebes in Brandenburg unter Verwendung von realen Ertrags- und Wetterdaten mit Hilfe einer stochastischen Simulation die risikomindernde Wirkung quan-tifiziert, die durch den Einsatz von Niederschlagsoptionen erzielt werden kann. Dabei wird die Hedging-Effektivität durch das Kontraktdesign (Index, Strike-Preis, Tick-Size) gesteuert. Das Basisrisiko der Produktion und das geografische Basisrisiko verbleiben jedoch in jedem Fall beim Landwirt. Ziel ist es, beide Basisrisiken zu separieren und in ihrer Höhe auszuweisen. Dies erlaubt Rückschlüsse für die Gestaltung von Wetterderivaten. Somit ist die hier behandelte Fragestellung sowohl für Landwirte als auch für potenzielle Anbieter von Wetterderivaten rele-vant.

description: Η διατριβή αυτή αναλύει τον αντίκτυπο της τρέχουσας πανδημίας COVID-19 στη ναυτιλιακή βιομηχανία και ιδιαίτερα στη ζωή των ναυτικών. Παρέχει πληροφορίες στους πλοιοκτήτες και χειριστές σχετικά με τη διαχείριση τόσο του στόλο όσο και των ναυτικών κατά την διάρκεια αυτής της δύσκολης περιόδου. To διεθνές ναυτικό επιμελητήριο δημιούργησε εργαλεία για να βοηθήσει τους χειριστές πλοίων να αντιμετωπίσουν περιπτώσεις επί του πλοίου: ένα διάγραμμα ροής που θα βοηθήσει να προσδιοριστεί η διαδικασία που θα ακολουθηθεί κατά τη διαχείριση ενός μεγαλύτερου αριθμού ύποπτων περιπτώσεων COVID-19 επί του πλοίου και έναν πίνακα διαδικασιών δοκιμής PCR που θα βοηθήσει στον προσδιορισμό του τι πρέπει να γίνεται πριν από την επιβίβαση καθώς και αν εντοπιστεί ύποπτη περίπτωση επί του πλοίου. Επιπλέον, αναλύεται η άνευ προηγουμένου πρόκληση για τα πιστοποιητικά ναυτικών, συμπεριλαμβανομένων των ιατρικών πιστοποιητικών, που λήγουν ενώ οι ναυτικοί εξακολουθούν να βρίσκονται σε πλοία ή στο σπίτι περιμένοντας να ναυτολογηθούν , χωρίς δικό τους λάθος, λόγω των περιστάσεων που έχουν προκύψει εξαιτίας της πανδημία COVID-19. Επιπλέον παρέχει πληροφορίες σχετικά με τα αίτια, τις συνέπειες και τη διαχείριση της κόπωσης βάσει των κατευθυντήριων γραμμών του Διεθνούς Ναυτιλιακού Οργανισμού για την κόπωση (MSC.1 / Circ. 1598). Οι συνέπειες της κόπωσης για την υγεία και την ασφάλεια των ναυτικών έχουν προκαλέσει ανησυχία στη βιομηχανία και υποδηλώνουν τη σημασία της περαιτέρω έρευνας για παράγοντες κινδύνου και προληπτικές παρεμβάσεις στη θάλασσα. Τέλος, αναφέρεται σε κατευθυντήριες γραμμές για την προστασία της υγείας, του επαναπατρισμού και της ταξιδιωτικής οργάνωσης των ναυτικών, επιβατών και άλλων ατόμων σε πλοία. Λαμβάνοντας όλα αυτά υπόψη ο ΟΗΕ, το ICS, η ITF και άλλοι πλησίασαν διάφορες κυβερνήσεις προκειμένου να διασφαλίσουν ότι οι χώρες αναγνωρίζουν τους ναυτικούς ως βασικούς εργαζόμενους και συνεπώς απαλλάσσονται από τους περιορισμούς καραντίνας και ταξιδιού που επιβάλλονται στο κοινό.

We have enriched highly purified CD34+ cells from cord blood, determined in vitro growth of the cells in culture systems in the absence (condition A) or presence of GM-CSF and G-CSF (condition B), and determined the profile of immune cells during the period of cultivation by using flow cytometry. PhytohemagglutininA (PHA) was used as a mitogen to stimulate T lymphocytes derived from hematopoietic stem cells. GM-CSF and G-CSF prolonged the survival of the growing cells and also maintained expansion of cells in blastic stage. By day 12 of cultivation, when cell numbers peaked, various types of immune cells had appeared (CD14+ cells, CD40+HLA-DR+ cells, CD3+CD56+ cells, CD19+ cells, CD3+CD4+ cells, CD3+CD8+cells and CD3-CD56+). A significantly higher percentage of monocytes (p = 0.002) were observed under culture with GM-CSF, G-CSF when compared with culture without GM-CSF, G-CSF. In addition, T lymphocytes derived from HSC responded to 50 μg/ml of PHA. This is the first report showing the complete differentiation and proliferation of immune cells derived from CD34+ HSC under in vitro culture conditions. Lymphocytes, monocytes, dendritic cells and polymorph nuclear cells derived from HSC in vitro are unique, and thus may benefit various studies such as innate immunity and pathophysiology of immune disorders.

description: The past decade has seen a rapid penetration of electric vehicles (EV) in the market, more and more logistics and transportation companies start to deploy EVs for service provision. In order to model the operations of a commercial EV fleet, we utilize the EV routing problem with time windows (EVRPTW). In this research, we propose an end-to-end deep reinforcement learning framework to solve the EVRPTW. In particular, we develop an attention model incorporating the pointer network and a graph embedding technique to parameterize a stochastic policy for solving the EVRPTW. The model is then trained using policy gradient with rollout baseline. Our numerical studies show that the proposed model is able to efficiently solve EVRPTW instances of large sizes that are not solvable with any existing approaches.

description: We propose a generalization of the condition for harmonic spatial coordinates analogous to the generalization of the harmonic time slices introduced by Bona et al., and closely related to dynamic shift conditions recently proposed by Lindblom and Scheel, and Bona and Palenzuela. These generalized harmonic spatial coordinates imply a condition for the shift vector that has the form of an evolution equation for the shift components. We find that in order to decouple the slicing condition from the evolution equation for the shift it is necessary to use a rescaled shift vector. The initial form of the generalized harmonic shift condition is not spatially covariant, but we propose a simple way to make it fully covariant so that it can be used in coordinate systems other than Cartesian. We also analyze the effect of the shift condition proposed here on the hyperbolicity of the evolution equations of general relativity in 1+1 dimensions and 3+1 spherical symmetry, and study the possible development of blow-ups. Finally, we perform a series of numerical experiments to illustrate the behavior of this shift condition.

description: We solve an open problem of Diaconis that asks what are the largest orders of $p_n$ and $q_n$ such that $Z_n,$ the $p_n\times q_n$ upper left block of a random matrix $\boldsymbolΓ_n$ which is uniformly distributed on the orthogonal group O(n), can be approximated by independent standard normals? This problem is solved by two different approximation methods. First, we show that the variation distance between the joint distribution of entries of $Z_n$ and that of $p_nq_n$ independent standard normals goes to zero provided $p_n=o(\sqrt{n})$ and $q_n=o(\sqrt{n})$. We also show that the above variation distance does not go to zero if $p_n=[x\sqrt{n} ]$ and $q_n=[y\sqrt{n} ]$ for any positive numbers $x$ and $y$. This says that the largest orders of $p_n$ and $q_n$ are $o(n^{1/2})$ in the sense of the above approximation. Second, suppose $\boldsymbolΓ_n=(γ_{ij})_{n\times n}$ is generated by performing the Gram--Schmidt algorithm on the columns of $\bold{Y}_n=(y_{ij})_{n\times n}$, where $\{y_{ij};1\leq i,j\leq n\}$ are i.i.d. standard normals. We show that $ε_n(m):=\max_{1\leq i\leq n,1\leq j\leq m}|\sqrt{n}\cdotγ_{ij}-y_{ij}|$ goes to zero in probability as long as $m=m_n=o(n/\log n)$. We also prove that $ε_n(m_n)\to 2\sqrtα$ in probability when $m_n=[nα/\log n]$ for any $α>0.$ This says that $m_n=o(n/\log n)$ is the largest order such that the entries of the first $m_n$ columns of $\boldsymbolΓ_n$ can be approximated simultaneously by independent standard normals.

description: Fibrodysplasia ossificans progressiva (FOP) is a very rare disorder with a worldwide prevalence of approximately 1 in 2 million population. The age of onset is mostly in the first two decades of life, and there is no ethnic, racial, gender, or geographic predilection of FOP. Stone man syndrome is also known Fibrodysplasia ossificans progressiva (FOP) is an extremely rare genetic disorder which is characterised by heterotopic ossification of the connective tissue and congenital malformation of the big toes. Currently this disease exists in 67 countries with 834 confirmed cases across the world. The FOP is caused by the mutation in the gene ACVR1 (ALK2). The symptoms of FOP are bone forming on muscles, ligaments, and connective tissue, decreased mobility, difficulty eating or speaking, hearing impairment etc., are the symptoms for the FOP.  The diagnosis of the FOP can be done by plain X-rays can reveal abnormal osteogenesis after heterotopic ossification manifests. CT scan can also show lesions with typical heterotrophic ossification. MRI can reveal pre-osseous lesions, which appear as soft tissue swelling and skeletal malformations. There is no single effective treatment option available for fibrodysplasia ossificans progressive. Mast cell inhibitors, NSAIDS, amino bisphosphonates, and COX-2 inhibitors are used for treating later flare-ups. We need to spread knowledge to physicians and patients’ family members about the disease, as well as its features for early diagnosis and how to prevent flare-up of the disease to promote better quality of life in these patients. This includes most recent updates in the definition, epidemiology, signs and symptoms, etiopathogenesis, and treatment of FOP. We need to educate clinicians and patients' families concerning the disease, as well as its symptoms for early detection and how to prevent flare-ups, in order to improve quality of life.

Key words: Stone man syndrome, fibrodysplasia ossificans progressiva, COX-2 inhibitors.

description: Despite the significance of short-term memory in cognitive function, the process of encoding and sustaining the input information in neural activity dynamics remains elusive. Herein, we unveiled the significance of transient neural dynamics to short-term memory. By training recurrent neural networks to short-term memory tasks and analyzing the dynamics, the characteristics of the short-term memory mechanism were obtained in which the input information was encoded in the amplitude of transient oscillations, rather than the stationary neural activities. This transient trajectory was attracted to a slow manifold, which permitted the discarding of irrelevant information. Additionally, we investigated the process by which the dynamics acquire robustness to noise. In this transient oscillation, the robustness to noise was obtained by a strong contraction of the neural states after perturbation onto the manifold. This mechanism works for several neural network models and tasks, which implies its relevance to neural information processing in general.

description: The present paper presents a tabulation of data on all 600 Galactic open clusters for which it is presently possible to calculate linear diameters. As expected, the youngest `clusters' with ages < 15 Myr, contain a significant (greater than or equal to 20%) admixture of associations. Among intermediate-age clusters, with ages in the range 15 Myr to 1.5 Gyr, the median cluster diameter is found to increase with age. Small compact clusters are rare among objects with ages > 1.5 Gyr. Open clusters with ages > 1 Gyr appear to form what might be termed a `cluster thick disk', part of which consistst of objects that were probably captured gravitationally by the main body of the Galaxy.

description: We derive a low-energy effective theory for gravity with anti-D branes, which are essential to get de Sitter solutions in the type IIB string warped compactification, by taking account of gravitational backreactions of anti-D branes. In order to see the effects of the self-gravity of anti-D branes, a simplified model is studied where a 5-dimensional anti-de Sitter ({\it AdS}) spacetime is realized by the bulk cosmological constant and the 5-form flux, and anti-D branes are coupled to the 5-form field by Chern-Simon terms. The {\it AdS} spacetime is truncated by introducing UV and IR cut-off branes like the Randall-Sundrum model. We derive an effective theory for gravity on the UV brane and reproduce the familiar result that the tensions of the anti-D branes give potentials suppressed by the forth-power of the warp factor at the location of the anti-D branes. However, in this simplified model, the potential energy never inflates the UV brane, although the anti-D-branes are inflating. The UV brane is dominated by dark radiation coming from the projection of the 5-dimensional Weyl tensor, unless the moduli fields for the anti-D branes are stabilized. We comment on the possibility of avoiding this problem in a realistic string theory compactification.

description: We describe the first version (v1.00) of the code HFBRAD which solves the Skyrme-Hartree-Fock or Skyrme-Hartree-Fock-Bogolyubov equations in the coordinate representation within the spherical symmetry. A realistic representation of the quasiparticle wave functions on the space lattice allows for performing calculations up to the particle drip lines. Zero-range density-dependent interactions are used in the pairing channel. The pairing energy is calculated by either using a cut-off energy in the quasiparticle spectrum or the regularization scheme proposed by A. Bulgac and Y. Yu.

description: Poly(2‐oxazoline)s (POxs) with 2,2′‐iminodiacetate (IDA) end groups were investigated as inhibitors for laccase. The polymers with the IDA end groups are reversible, competitive inhibitors for this enzyme. The IC50 values were found to be in a range of 1–3 mm. Compared with IDA alone, the activity was increased by a factor of more than 30; thus indicating that attaching a polymer chain to an inhibitor can already improve the activity of the former. The enzyme activity drops to practically zero upon increasing the concentration of the most active telechelic inhibitor, IDA‐PEtOx30‐IDA (PEtOx: poly(2‐ethyl‐2‐oxazoline)), from 5 to 8 mm. This unusual behavior was investigated by means of dynamic light scattering, which showed specific aggregation above 5 mm. Furthermore, the laccase could be stabilized in the presence of POx‐IDA, upon addition at a concentration of 20 mm and higher. Whereas laccase becomes completely inactive at room temperature after one week, the stabilized laccase is fully active for at least a month in aqueous solution.
