description: We study numerically the Kawasaki dynamics of the 2d Ising model. At large time we recover the coarsening growth as l(t) ~ t^(1/3). At shorter time however, the system enters a metastable glassy regime that displays an extremely slow growth and non-trivial violations of the fluctuation dissipation theorem similar to those observed in spin glasses: this is one of the simplest system where such violations occur. We also consider Potts models, where a similar behavior is observed, and the modelof Shore and Sethna where the domain growth is also slow, but where violations of the fluctuation dissipation theorem are trivial. We finally comment on these violations in the context of activated coarsening, and on similarities and differences with the glass transition phenomenology.

description: Purpose: To develop a machine learning model to classify the severity grades of pulmonary edema on chest radiographs. Materials and Methods: In this retrospective study, 369,071 chest radiographs and associated radiology reports from 64,581 (mean age, 51.71; 54.51% women) patients from the MIMIC-CXR chest radiograph dataset were included. This dataset was split into patients with and without congestive heart failure (CHF). Pulmonary edema severity labels from the associated radiology reports were extracted from patients with CHF as four different ordinal levels: 0, no edema; 1, vascular congestion; 2, interstitial edema; and 3, alveolar edema. Deep learning models were developed using two approaches: a semi-supervised model using a variational autoencoder and a pre-trained supervised learning model using a dense neural network. Receiver operating characteristic curve analysis was performed on both models. Results: The area under the receiver operating characteristic curve (AUC) for differentiating alveolar edema from no edema was 0.99 for the semi-supervised model and 0.87 for the pre-trained models. Performance of the algorithm was inversely related to the difficulty in categorizing milder states of pulmonary edema (shown as AUCs for semi-supervised model and pre-trained model, respectively): 2 versus 0, 0.88 and 0.81; 1 versus 0, 0.79 and 0.66; 3 versus 1, 0.93 and 0.82; 2 versus 1, 0.69 and 0.73; and, 3 versus 2, 0.88 and 0.63. Conclusion: Deep learning models were trained on a large chest radiograph dataset and could grade the severity of pulmonary edema on chest radiographs with high performance.

description: We present a theoretical model to investigate the interference of an array of Bose-Einstein condensates loaded in a one-dimensional spin-dependent optical lattice, which is based on an assumption that for the atoms in the entangled single-atom state between the internal and the external degrees of freedom each atom interferes only with itself. Our theoretical results agree well with the interference patterns observed in a recent experiment by Mandel et al. [Phys. Rev. Lett. 91, 010407 (2003)]. In addition, an experimental suggestion of nonuniform phase distribution is proposed to test further our theoretical model and prediction. The present work shows that the entanglement of a single atom is sufficient for the interference of the condensates confined in a spin-dependent optical lattice and this interference is irrelevant with the phases of individual condensates, i.e., this interference arises only between each condensate and itself and there is no interference effect between two arbitrary different condensates.

description: Time-bin qubits, where information is encoded in a single photon at different times, have been widely used in optical fiber and waveguide based quantum communications. With the recent developments in distributed quantum computation, it is logical to ask whether time-bin encoded qubits may be useful in that context. We have recently realized a time-bin qubit controlled-phase (C-Phase) gate using a 2 X 2 optical switch based on a lithium niobate waveguide, with which we demonstrated the generation of an entangled state. However, the experiment was performed with only a pair of input states, and thus the functionality of the C-Phase gate was not fully verified. In this research, we used quantum process tomography to establish a process fidelity of 97.1%. Furthermore, we demonstrated the controlled-NOT gate operation with a process fidelity greater than 94%. This study confirms that typical two-qubit logic gates used in quantum computational circuits can be implemented with time-bin qubits, and thus it is a significant step forward for realization of distributed quantum computation based on time-bin qubits.

description: This article presents the artefacts found during the excavation of a building at Napurvala Hill, Pichvnari, in the 1960s and 1970s and now at the Batumi Archaeological Museum (BAM). Besides discussing the bulk finds, some of which were already published in 1980 by Chkhaidze, this contribution provides, for the first time, a study of a small white marble cross found during the excavation and now on display at the BAM. It will conclude that, although the interpretation of the building as a church remains sound, the chronology of the artefacts is problematic as their dating ranges from the Hellenistic to the Medieval periods.

description: In this work we explore the geodesic deviations of spinning test particles in a string inspired Einstein-Kalb Ramond background. Such a background is known to be equivalent to a spacetime geometry with torsion. We have shown here that the antisymmetric Kalb-Ramond field has significant effect on the geodesic deviation of a spinning test particle. A search for an observational evidence of such an effect in astrophysical experiments may lead to a better undestanding of the geometry of the background spacetime.

description: Combining high time and frequency resolution full-polarisation spectra of Fast Radio Bursts (FRBs) with knowledge of their host galaxy properties provides an opportunity to study both the emission mechanism generating them and the impact of their propagation through their local environment, host galaxy, and the intergalactic medium. The Australian Square Kilometre Array Pathfinder (ASKAP) telescope has provided the first ensemble of bursts with this information. In this paper, we present the high time and spectral resolution, full polarisation observations of five localised FRBs to complement the results published for the previously studied ASKAP FRB~181112. We find that every FRB is highly polarised, with polarisation fractions ranging from 80 -- 100\%, and that they are generally dominated by linear polarisation. While some FRBs in our sample exhibit properties associated with an emerging archetype (i.e., repeating or apparently non-repeating), others exhibit characteristic features of both, implying the existence of a continuum of FRB properties. When examined at high time resolution, we find that all FRBs in our sample have evidence for multiple sub-components and for scattering at a level greater than expected from the Milky Way. We find no correlation between the diverse range of FRB properties (e.g., scattering time, intrinsic width, and rotation measure) and any global property of their host galaxy. The most heavily scattered bursts reside in the outskirts of their host galaxies, suggesting that the source-local environment rather than the host interstellar medium is likely the dominant origin of the scattering in our sample.

Phasian Confusion. Notes on Kolchian, Armenian and Pontic River Names in Myth, History and Geography
Creators: name: Coşkun, Altay
Publisher: name: PHASIS
Year: 2019

description: Due to its close link with the legendary kingdom of Aia, where the Argonauts found the Golden Fleece, the Kolchian Phasis is one of the most illustrious rivers in world literature. It is, at the same time, surrounded by several controversies, ancient as well as modern. The evidence seems to suggest that it was first pictured as part of the mythical landscape around 500 B.C. Mythical narratives, colonial ideologies, reports of explorers and geographical speculation led to a heterogeneous, in part fancy tradition, as is best exemplified by the Phasis/Tanaïs/Don, which was fathomed with a second outlet into the Baltic Sea. This notwithstanding, the concept of the Kolchian Phasis was quite sober. Eratosthenes, Strabo and the mainstream literary tradition identified it with the modern Rioni only as far as Rhodopolis/Geguti, whence its middle course equals the Kvirila River to Sarapana/Shoropani; its upper course, now the Barimela, connected it with its Armenian source. The knowledge that Herodotos and Xenophon had of the Phasis/Rioni and of the Araxes/Phasis/Aras was limited but not confused. Prokopios, however, describes the Boas/Akampsis as the upper course of the Phasis/Kvirila/Rioni in Book 2, but corrects this view in Book 8. His error stands in a broader tradition that ignored the Akampsis, possibly due to confusion with multiple rivers called Lykoi in the Argonautic and geographical literature. This insight will allow us to demystify Apollonios Rhodios’ verses on the Phasis, Lykos and Araxes, and to appreciate the minor rivers of the riverscape of Aia: the Hippos, Kyaneos, Glaukos and Lykos, whose systematic study remains a desideratum.

Stopping and response control : application of a novel tracking task
Creators: name: Morein-Zamir, Sharon
Publisher: name: University of British Columbia
Year: 2010

description: Stopping a planned or ongoing action is one of the central methods for examining response control and inhibition. This research area has been dominated by the application of the "stop-signal paradigm" which measures the inhibition of a planned action (Chapter 1). Chapter 2 describes two experiments on the development and initial testing of my novel tracking task which measures the inhibition of an ongoing action. Over the next three chapters this tracking task is used to examine three fundamental assumptions of stopping research. The first assumption is that all forms of stopping are mediated by a common mechanism. The investigation reported in Chapter 3 supports this idea as the classic stop-signal task and the novel tracking task are shown to tap into the same inhibitory mechanism. The second assumption is that stopping is governed by different constraints than those governing response initiation. Chapter 4 reports two experiments that argue against this position, as stopping and response initiation are found to be influenced similarly by manipulations to stimulus-response compatibility. The third assumption is that stopping generalizes to other measures of response modification. Chapter 5 reports three experiments that support this third assumption, with expectancy effects having a comparable influence on response inhibition and acceleration. These data also provide converging evidence for a rejection of the second assumption that stopping is unique. Chapter 6 concludes with a summary and integration of the main findings, an exploration of the practical and theoretical implications of the work, and finally, a consideration of some outstanding questions and future directions in the field of response control and inhibition.
title: Linked independent junior schools : an investigation into what head teachers perceive to be the influence of autonomy on school effectiveness, in terms of shared leadership and management
Creators: name: Diggory, Colin
Publisher: name: The Open University
Year: 2005

description: The provision of junior school education in the independent sector includes junior schools that are attached, or 'linked', to 'senior' schools (i. e. secondary schools). Within pairs of linked schools, a key issue to emerge is the degree of autonomy granted to the junior school head teacher and how this is thought to influence the effectiveness of his or her school. Head teachers sometimes use different criteria in judging junior school effectiveness and have different understandings of the concept of autonomy. Therefore they may not share the same expectation of how much, or what kind of, autonomy should be given. However, pairs of head teachers have to develop ways of sharing power and leadership through their organisational structures, as they interpret their concepts of autonomy in a mutually dependent relationship, whilst seeking to understand and support each other's aims for improving the effectiveness of the junior school. The research used a questionnaire survey and follow-up interviews to assess, from the perspective of a head teacher, how autonomy is thought to influence the effectiveness of the junior school. The main survey findings, partly validated using triangulation with interview data, showed that head teachers generally understood a high degree of autonomy to mean having decision-making power over appointing staff, setting budgets, allocating resources, selecting pupils and controlling capital development. The findings from questionnaire and interview data showed that junior and senior school head teachers sometimes used different criteria when judging junior school effectiveness but there was a good mutual understanding between the two groups. Furthermore, there was general agreement that for a junior school to be considered effective it had to have professional leadership promoting a shared vision, with good inter-personal relations operating within a well-resourced learning community that sets high expectations. In relation to these understandings of the terms autonomy and school effectiveness and within the context of this study, there was strong evidence to support the view that all head teachers surveyed generally thought that junior schools benefit from increased autonomy by becoming more effective. No significant evidence directly linked autonomy or effectiveness with particular organisational structures, but the way in which heads operated within a given structure was seen as important. With regard to professional practice, in cases of a high degree of autonomy operating, there was evidence of pairs of head teachers having a shared approach to leadership, with a collaborative and participative approach to decision-making and management

description: The article examines the status of king Cogidubnus and the existence of the kingdom, which various historians attributed to him hitherto. After a short description of the sources and research approaches to this issue, it will reveal that there are no evidences or strong indices for his kingdom and many points even contradict this research postulate. On this basis, the existence of a client kingdom in Julio-Claudian Britain will be deconstructed. Associated with this, also new approaches on the position of king Cogidubnus and the use of client kings by the Roman provincial administration will be discussed.

description: Napjainkban az Európai Unió vidékfejlesztési gyakorlatában háromféle beavatkozás érvényesül amelyek vidékfejlesztési célokat fogalmaznak meg: az 1257/1999-es számú Vidékfejlesztési Rendelet által támogatott intézkedések, a LEADER + Program és az 1-es és 2-es célterületeken folytatható vidékfejlesztés. A legnagyobb politikai publicitást és támogatási keretet a mezőgazdaság reformjához kötött elsőként említett vidékfejlesztés kapott. A vizsgált tagállamokban ennek domináns része környezetbarát gazdálkodási módszerek és a kedvezőtlen területeken gazdálkodók támogatására fordítódik. A fogyasztók elvárásaira hivatkozva a Bizottság a jövőben a KAP-hoz kapcsolt vidékfejlesztési beavatkozások körét tovább bővíti élelmiszer-biztonsági és állatvédelmi intézkedésekkel, amelyre a csatlakozó országoknak is nagyobb figyelmet kell szentelni a jövőben. --------------- At present three types of intervention aimed at rural development are practised by the European Union: measures supported by the Rural Development Regulation No. 1257/1999; the LEADER + Programme; and rural development to be practised in target regions No. 1 and 2. The first of these measures, attached to the CAP reform, were given greatest political publicity and highest subsidisation. In member states studied by the author the predominating part of these subsidies is allocated to the support of farmers using environmentally friendly techniques or farming under unfavourable conditions. Referring to consumes’ expectations the Commission is going to widen the scope of rural development interventions by means of including food safety and animal protection measures. This has to be taken into consideration also by countries presently entering into the European Union.

description: This paper describes our German and English Speech-to-Text (STT) systems for the 2017 IWSLT evaluation campaign. The campaign focuses on the transcription of unsegmented lecture talks. Our setup includes systems using both the Janus and Kaldi frameworks. We combined the outputs using both ROVER [1] and confusion network combination (CNC) [2] to achieve a good overall performance. The individual subsystems are built by using different speaker-adaptive feature combination (e.g., lMEL with i-vector or bottleneck speaker vector), acoustic models (GMM or DNN) and speaker adaptation (MLLR or fMLLR). Decoding is performed in two stages, where the GMM and DNN systems are adapted on the combination of the first stage outputs using MLLR, and fMLLR. The combination setup produces a final hypothesis that has a significantly lower WER than any of the individual sub-systems. For the English lecture task, our best combination system has a WER of 8.3% on the tst2015 development set while our other combinations gained 25.7% WER for German lecture tasks.

description: Despite numerous efforts, the transition from Asymptotic Giant Branch (AGB) stars to Planetary Nebulae (PN) is a poorly understood phase of stellar evolution. We have therefore carried out interferometric (VLA) radio observations of a sample of hot post-AGB stars, selected on the basis of their optical and infrared properties. Ten sources out of the 16 observed were detected. This indicates that most of our targets are surrounded by a nebula where the ionization has already started. This definitively determines the evolutionary status of the selected sources and provides us with a unique sample of very young Planetary Nebulae (yPNe). A comparison with another sample of yPNe confirms our working hypothesis that our targets are indeed very young, probably just in the transition toward PN. Finding transition objects is extremely important as they can provide unique clues for a better understanding of this important phase of stellar evolution.

description: Agro-industrialization together with consolidation processes between agribusiness entities, especially between agricultural production and agri-food sector, make the analysis of coordination processes between farmers (producers’ organizations) and food sector an important research issue. The goal of this paper is thus to provide characteristics for modes of transaction coordination between poultry producers’ organizations and their buyers taking into a special account formal/contractual relations. For the purpose of the research the author applied a questionnaire method which was conducted between March and May 2015. The sample was 67 poultry producers’ organizations covering their activities in the year 2014. Conducted research revealed that 73% of respondents sold the whole production of their members to processing plants and most transactions of poultry producers’ organizations were completed under contractual framework.

description: Urban planning refers to the efforts of designing land-use configurations. Effective urban planning can help to mitigate the operational and social vulnerability of a urban system, such as high tax, crimes, traffic congestion and accidents, pollution, depression, and anxiety. Due to the high complexity of urban systems, such tasks are mostly completed by professional planners. But, human planners take longer time. The recent advance of deep learning motivates us to ask: can machines learn at a human capability to automatically and quickly calculate land-use configuration, so human planners can finally adjust machine-generated plans for specific needs? To this end, we formulate the automated urban planning problem into a task of learning to configure land-uses, given the surrounding spatial contexts. To set up the task, we define a land-use configuration as a longitude-latitude-channel tensor, where each channel is a category of POIs and the value of an entry is the number of POIs. The objective is then to propose an adversarial learning framework that can automatically generate such tensor for an unplanned area. In particular, we first characterize the contexts of surrounding areas of an unplanned area by learning representations from spatial graphs using geographic and human mobility data. Second, we combine each unplanned area and its surrounding context representation as a tuple, and categorize all the tuples into positive (well-planned areas) and negative samples (poorly-planned areas). Third, we develop an adversarial land-use configuration approach, where the surrounding context representation is fed into a generator to generate a land-use configuration, and a discriminator learns to distinguish among positive and negative samples.

The Metamorphosis of Daphnis from Theocritus to Virgil
Creators: name: Gagliardi, Paola
Publisher: name: PHASIS
Year: 2019

description: The character of Daphnis, who has intriguing significance in folklore and religion, becomes an important literary figure in Theocritus, who, in his narrative of Daphnis’ death, makes him the founding figure of his new genre, bucolic poetry. Theocritus’ successors, Bion of Smyrna in his Adonidis Epitaphium, and the anonymous author of Bionis Epitaphium, refer to Daphnis – inevitably the Theocritean Daphnis – and transform his figure, adapting it to the themes and purposes of their poems. After them, in founding Latin bucolic poetry, Virgil appropriates Daphnis, not only in order to pay tribute to the previous literary tradition, but as a point of departure (and of arrival) in his reflection on bucolic poetry and his relationship with his great Syracusan predecessor. The paper aims to retrace the path of Daphnis, to understand, in the treatment reserved for him by each poet, the elements of vitality and originality that his great inventor Theocritus gave him and that his successors developed at different levels. Virgil, in particular, is able to employ the figure of Daphnis and charge it with a new significance, in order to highlight the great difference between his own poetry and Theocritus’ bucolic production.

description: As a result of over 24 years of management of agricultural property of the State Treasury, from 807 thous. ha properties which were overtaken, 80.3% were firmly disposed (mainly through sales). Lease continues being significant as 120.1 thousands ha of land (14.9%) are being leased. Aim of this research was to identify determinants of management of agricultural properties of the State Treasury in Warmia-Masuria province. Analysis based on reports on the activity of APA’s Territorial branch in Olsztyn and results of questionnaires filled in by people who manage farms on properties leased or purchased from the State Treasury. Results of this questionnaires state that factors influencing profitability of farm production (shaped for instance by prices of production resources, farm production costs, demand on products of the farm or by unstable prices of purchase) were most significant. Resource factors resulting from possessing proper machine park, equity for development and quality of possessed/leased lands were also important for managing a farm.

description: Prostate cancer is the most frequently diagnosed cancer as well as the second leading cause of cancer deaths among American men. Androgen deprivation therapy for patients with advanced prostate cancer inevitably fails as the disease progresses to the terminal, hormone-refractory stage. At the present time no effective therapies can be offered to patients in this stage of the disease. Currently, the molecular alterations that contribute to the development of hormone-refractory disease are poorly understood. Here, suppression subtractive hybridization was performed to identify genes of interest in a model of progression of prostate cancer to androgen independence. Subtractive hybridization identified a number of novel transcripts that had previously not been described. From this work it was hypothesized that (1) the novel transcripts identified may prove informative in the clinical management of prostate cancer, and (2) that the known genes identified may function in the progression of prostate cancer. One of these novel transcripts was shown to encode a truncated splice variant of the transmembrane protein TMEFF2. TMEFF2 is specifically expressed in the prostate and the brain, and other groups have developed antibodies targeting TMEFF2 for the treatment of metastatic prostate cancer. The isoform described here, TMEFF2-S, encodes a protein secreted by prostate cancer cells. Being a prostate-specific, secreted protein, TMEFF2-S may prove informative in predicting patient outcome. Additionally, the secretion of TMEFF2-S may influence the effectiveness of immunotherapy approaches targeting TMEFF2. Subtractive hybridization, together with other high-throughput screening techniques, also led to the examination of the potential functions of the 14-3-3 family of proteins in the progression of prostate cancer. These experiments demonstrated that 14-3-3 sigma specifically increased the activity of the androgen receptor in the absence of androgens. Thus, this finding may have implications for patients undergoing androgen deprivation therapy. Further studies will be required to determine if 14-3-3 sigma is active in a subset of patients with hormone refractory prostate cancer. If so, its role in activating the androgen receptor may potentially be targeted for the development of novel therapeutics for the treatment of hormone-refractory disease.

description: This paper provides an update to Roger Pack’s 1972 article “On the Greek Chiromantic Fragment” (TAPA 103: 367-380). The discovery of several new witnesses to the text warrants a reconsideration of the scholarly questions about Greek chiromancy. This paper presents the results of recent scholarship on the Greek chiromantic fragment, alongside a new edition of the text and a survey of its reception.

description: The article was aimed to answer the question of whether there is a relationship between the intellectual capital of the countryside inhabitants and the level of living in rural areas. The analysis was carried out for Polish provinces in 2013. All empirical data were derived from public statistics. Due to the complex nature of both categories, the evaluations of their levels were based on the synthetic variables. Because some distributions of variables have been asymmetrical, the positional models of Hellwig’s development measure were used. The measures of development for both categories were highly diversified so they formed the basis of the typology. Based on the synthetic measure of development the rankings of regions were created. Then the provinces were also divided and classified into similar groups. In order to test the hypothesis about the relationship between the intellectual capital and the level of living in rural areas, the correlation between the values of measures of development was analysed. The concordance of rankings was verified as well. None of the studies confirmed no statistically significant relationship between the considered categories.

description: The basic methods of constructing the sets of mutually unbiased bases in the Hilbert space of an arbitrary finite dimension are discussed and an emerging link between them is outlined. It is shown that these methods employ a wide range of important mathematical concepts like, e.g., Fourier transforms, Galois fields and rings, finite and related projective geometries, and entanglement, to mention a few. Some applications of the theory to quantum information tasks are also mentioned.

Zwischen traditioneller Rhetorik und sokratischer (Anti-)Rhetorik. Einige neue Βemerkungen über das Proömium von Platons "Apologie des Sokrates" (17a1-18a6)

description: In this paper my aim is to show how Socrates’ critique of contemporary rhetoric in the preamble of the Apology is indirectly but clearly addressed to the Homeric value system. Socrates’ contemporary litigants, heirs to the competitive ethics embodied in the Homeric epics, are observed to devote themselves to employing devious tricks and cunning in order to win court cases. Socrates, however, sets out to plead the cause of truth and justice, and will defend himself against his accusers by means of these conceptual “tools.” It is clear, therefore, that Socrates’ principal aim is to redefine traditional rhetoric by formulating new goals and expected outcomes: rhetoric must not distort the truth but reveal it so that it can be readily grasped by the audience.

description: It is widely expected that at sufficiently high temperatures order is always lost, e.g. magnets loose their ferromagnetic properties. We pose the question of whether this is always the case in the context of quantum field theory in $d$ space dimensions. More concretely, one can ask whether there exist critical points (CFTs) which break some global symmetry at arbitrary finite temperature. The most familiar CFTs do not exhibit symmetry breaking at finite temperature, and moreover, in the context of the AdS/CFT correspondence, critical points at finite temperature are described by an uncharged black brane which obeys a no-hair theorem. Yet, we show that there exist CFTs which have some of their internal symmetries broken at arbitrary finite temperature. Our main example is a vector model which we study both in the epsilon expansion and arbitrary rank as well as the large rank limit (and arbitrary dimension). The large rank limit of the vector model displays a conformal manifold, a moduli space of vacua, and a deformed moduli space of vacua at finite temperature. The appropriate Nambu-Goldstone bosons including the dilaton-like particle are identified. Using these tools we establish symmetry breaking at finite temperature for finite small $ε$. We also prove that a large class of other fixed points, which describe some of the most common quantum magnets, indeed behave as expected and do not break any global symmetry at finite temperature. We discuss some of the consequences of finite temperature symmetry breaking for the spectrum of local operators. Finally, we propose a class of fixed points which appear to be possible candidates for finite temperature symmetry breaking in $d=2$.

description: The aim of this paper was to analyze changes in the market of fruit and vegetable juices enterprises in Poland in general and individual provinces in the years 2003-2013. Analyses show that the production of fruit and vegetable juices is an industry that has a high development potential, as evidenced by the 80% increase in the number of enterprises producing this assortment in the years 2003-2013. Further development of this industry in the coming years may be stimulated by a systematic increase in exports of fruit and vegetable juices out of the country and not by the demand for these products in the domestic market.
ISO observations of the Galactic center Interstellar Medium: ionized gas

description: (Abridged) We present fine structure and recombination lines observations of the ionized gas toward a sample of 18 sources located within 300 pc of the center of the Galaxy (GC). The fine structure lines from [NII] and [SIII] have been detected in 16 sources. In 10 sources we have even detected the [OIII] 88 $μ$m line. The measured N, S and Ne abundances are similar to those measured in the HII regions in the 5-kpc ring and in the nuclei of starburst galaxies. The fine structure lines ratios measured for all the sources can be explained by photo-ionization with an effective temperature of 32000-37000 K and an ionization parameter, $U$, of $-1>\log U > -3$. The highest excitation is found in the Radio Arc region but there must be more ionizing sources distributed over the Galactic center than the known clusters of massive stars. Most of the clouds are located far from the prominent continuum complexes (Sgr C, B ...). However, it is possible that the clouds are ionized by escaped photons from those complexes. The excitation ratios, effective temperature and ionization parameter measured in the GC are similar to those found in some low excitation starburst galaxies. The [NeIII]/[NeII] line ratios measured in the GC sources are consistent with the results of the Thornely et al. (2000) model for a short burst of massive star formation less than 8 Myr ago. We have also found that the [NeII] 13 $μ$m ~ to far-infrared continuum ratio measured for the GC sources is similar to that of external galaxies, supporting the idea by Sturm et al. (2002) that the far-infrared continuum in Active Galaxies is dominated by dust heated by stellar radiation rather than by the AGN.

title: Analysis Of The Effects Of Metformin Administered Alone Or In Combined Treatments In Colorectal Cancer

description: The aim of this project was to investigate the anticancer activity of the anti-diabetic drug metformin, individually or combined in various settings with chemotherapy, on in vitro models of colorectal cancer (CRC). I found that metformin reduced cell proliferation by inducing cell cycle arrest in the G0/G1 phase, but did not lead to cell death. The anti-proliferative action of metformin resulted mediated by the inactivation of the mTOR pathway and of IGF1R protein. However, the drug only transiently arrested cell growth, since its effects were reversed after drug removal. When I combined the biguanide with the chemotherapy drugs commonly used to treat CRC I observed different responses in the cell lines analysed that reflected their genetic background and their different sensitivities to both the biguanide and chemotherapy. I found that metformin added before chemotherapy drugs antagonised their effects in the majority of the treatments. On the contrary, its administration after long chemotherapeutic treatments significantly reduced the cell viability. I noted that metformin better inhibits cell proliferation in cell lines with rapid growth. I have also assessed the dual treatment combination of metformin with different drugs that target specific genes or proteins (targeted therapies), focusing on BRAF-mutant cell lines. For most of the tested treatments the simultaneous administration of metformin and target drugs gave no advantages over the single drugs, and often resulted in antagonism. Overall, our results show that although further investigations are still needed to elucidate the results of the treaments including metformin, these data suggest that caution should be used in administering chemotherapy to indviduals taking metformin.
