description: Heparanase is an endo-{u03B2}-glucuronidase that cleaves heparan sulfate and facilitates the passage of migrating cells through extracellular matrices (ECM), particularly basement membranes, as well as releasing heparan sulfate-bound growth factors from the ECM, whereby the released growth factors also aid wound healing and angiogenesis. Under normal physiological conditions heparanase aids the passage of leukocytes through subendothelial basement membranes and entry into sites of inflammation. It is also well established that heparanase, via a similar mechanism, plays a critical role in the metastatic spread of cancer. Recent studies have suggested, however, that heparanase has biological functions independent of its enzymatic activity. A number of studies have also reported the presence of beparanase in the nucleus of cells, with nuclear heparanase being associated with a favourable prognosis and cytoplasmic beparanase with poor survival in patients with lung, neck and gastric cancers. There is some evidence that nuclear heparanase expression is linked to cancer cell differentiation but, despite such reports, the functional relevance of nuclear heparanase remains to be established. This thesis describes experiments which demonstrate that nuclear heparanase can regulate transcription in resting and activated human T lymphocytes. Initial immunofluorescence studies revealed that nuclear heparanase is associated with euchromatin, and not heterochromatin, in both resting and activated human T cells. Subsequent single locus ChIP as well as genome wide ChIP-on-chip analysis, identified a cohort of immune-related target genes that are bound by heparanase at their promoter and coding regions. Additional knockdown and over-expression experiments showed that chromatin-tethered heparanase is required for the inducible transcription of several of these genes in activated T cells. In fact, at the chromatin level, it was found that heparanase regulates histone H3K4 and H3K9 methylation, probably by binding to target gene control regions in association with the demethylase LSD1. It has been further shown that association of heparanase with the LSD1 complex is accompanied by a lack of recruitment of the methylase, MLL, suggesting that heparanase plays a central role in mediating the on/off switch of inducible gene transcription. Taken together, these data suggest a hitherto unanticipated role for nuclear heparanase as a novel chromatin-associated regulator of transcription in mammalian cells.

description: We study the entanglement production for Dirac and Klein-Gordon fields in an expanding spacetime characterized by the presence of torsion. Torsion is here considered according to the Einstein-Cartan theory with a conformally flat Friedmann-Robertson-Walker spacetime. In this framework, torsion is seen as an external field, fulfilling precise constraints directly got from the cosmological constant principle. For Dirac field, we find that torsion increases the amount of entanglement. This turns out to be particularly evident for small values of particle momentum. We discuss the roles of Pauli exclusion principle in view of our results, and, in particular, we propose an interpretation of the two maxima that occur for the entanglement entropy in presence of torsion. For Klein-Gordon field, and differently from the Dirac case, the model can be exactly solved by adopting the same scale factor as in the Dirac case. Again, we show how torsion affects the amount of entanglement, providing a robust physical motivation behind the increase or decrease of entanglement entropy. A direct comparison of our findings is also discussed in view of previous results derived in absence of torsion. To this end, we give prominence on how our expectations would change in terms of the coupling between torsion and the scale factor for both Dirac and Klein-Gordon fields.

description: Σε αυτή την πραγματεία περιγράφονται οι συνθήκες ζωής των Καππαδοκών και, επίσης, οι συνθήκες κάτω από τις οποίες αναγκάστηκαν να γίνουν πρόσφυγες, τόσο οι πολιτικές όσο και οι ιστορικές. Η σύμβαση για την Ανταλλαγή των Ελληνικών και τουρκικών Πληθυσμών, που υπογράφηκε στις 30 Ιανουαρίου 1923, σφράγισε με τον πιο θλιβερό τρόπο τη Μικρασιατική Καταστροφή. Με την υπογραφή της Συνθήκης της Λωζάννης, δόθηκε το τελειωτικό χτύπημα στον πολυπληθή ελληνικό πληθυσμό. Σύμφωνα με αυτή τη Συνθήκη, η θρησκεία θεωρείτο σημαντικότερο στοιχείο από τη γλώσσα. Ετσι, το καλοκαίρι του 1924 περίπου 6000 Ελληνες ορθόδοξοι κάτοικοι της Καππαδοκίας αναγκάστηκαν να εγκαταλείψουν τις πατρογονικές τους εστίες. Οι πρόσφυγες από τον Αραβησσό και το Ενεχίλ εγκαταστάθηκαν στη (Νέα) Αραβησσό, από την Αξό και Τροχό στη (Νέα) Αξό και από την Κουρούμτζα και το Τάστσι στο Νέο Μυλότοπο, κοντά στα Γιαννιτσά. Αναγκάστηκαν να αντιμετωπίσουν δυσκολίες, όπως το υγρό κλίμα, σοβαρές ασθένειες, ανθυγιεινές συνθήκες, φτώχεια, θάνατο. Εργάστηκαν σκληρά, με υπομονή και πίστη και αλληλεγγύη. Πρόκοψαν και ρίζωσαν στους καινούριους τόπους τους.
description: In this essay the living conditions of inhabitants, who come from Kappadokia, are discribed, and also which political and historical circumstances were forced them to become refugees. The agreement about the Exchange among Greek populations and Turkish, which had been signed on the 30th of January 1923, stamped in the most tragical way the calamity of Asia Minor. Signing the Lausanne treaty, the final blow to the multitudinous Greek nation was given. According to this treaty, religion was more important criterion for the ethnological existence of the inhabitants than language. So, in summer of 1924, about 6000 Greek orthodox inhabitants from Kappadokia were forced to abandon their ancestral homes. The refugees from Aravissos and Enehil were established in (New) Aravissos, from Axos and Troxos in (New) Axos and inhabitants from Couroumtza and Tastsi in New Milotopos, near Giannitsa. They were faced difficulties such as wet climate, diseases, unhealthy conditions poverty, death. They worked hard, with persistence and faith and solidarity. They made good and took roots in their new settlements.

description: Active fluids exhibit complex turbulent-like flows at low Reynolds number. Recent work predicted that 2d active nematic turbulence follows universal scaling laws. However, experimentally testing these predictions is conditioned by the coupling to the 3d environment. Here, we measure the spectrum of the kinetic energy, $E(q)$, in an active nematic film in contact with a passive oil layer. At small and intermediate scales, we find the scaling regimes $E(q)\sim q^{-4}$ and $E(q)\sim q^{-1}$, respectively, in agreement with the theoretical prediction for 2d active nematics. At large scales, however, we find a new scaling $E(q)\sim q$, which emerges when the dissipation is dominated by the 3d oil layer. In addition, we derive an explicit expression for the spectrum that spans all length scales, thus explaining and connecting the different scaling regimes. This allows us to fit the data and extract the length scale that controls the crossover to the new large-scale regime, which we tune by varying the oil viscosity. Overall, our work experimentally demonstrates the emergence of universal scaling laws in active turbulence, and it establishes how the spectrum is affected by external dissipation.

description: Pancreatic ductal adenocarcinoma (PDAC) is characterized by its nutrient-scavenging ability, crucial for tumor progression. Here, we investigated the roles of caveolae-mediated endocytosis (CME) in PDAC progression. Analysis of patient data across diverse datasets revealed a strong association of high caveolin-1 (Cav-1) expression with higher histologic grade, the most aggressive PDAC molecular subtypes, and worse clinical outcomes. Cav-1 loss markedly promoted longer overall and tumor-free survival in a genetically engineered mouse model. Cav-1-deficient tumor cell lines exhibited significantly reduced proliferation, particularly under low nutrient conditions. Supplementing cells with albumin rescued the growth of Cav-1-proficient PDAC cells, but not in Cav-1-deficient PDAC cells under low glutamine conditions. In addition, Cav-1 depletion led to significant metabolic defects, including decreased glycolytic and mitochondrial metabolism, and downstream protein translation signaling pathways. These findings highlight the crucial role of Cav-1 and CME in fueling pancreatic tumorigenesis, sustaining tumor growth, and promoting survival through nutrient scavenging.

description: We report diffusion quantum Monte Carlo calculations of three-dimensional Wigner crystals in the density range r_s=100-150. We have tested different types of orbital for use in the approximate wave functions but none improve upon the simple Gaussian form. The Gaussian exponents are optimized by directly minimizing the diffusion quantum Monte Carlo energy. We have carefully investigated and sought to minimize the potential biases in our Monte Carlo results. We conclude that the uniform electron gas undergoes a transition from a ferromagnetic fluid to a body-centered-cubic Wigner crystal at r_s=106+/-1. The diffusion quantum Monte Carlo results are compared with those from Hartree-Fock and Hartree theory in order to understand the role played by exchange and correlation in Wigner crystals. We also study "floating" Wigner crystals and give results for their pair-correlation functions.

description: This article reviews the history of open access (OA) policies and examines the current status of mandate policy implementations. It finds that hundreds of policies have been proposed and adopted at various organizational levels and many of them have shown a positive effect on the rate of repository content accumulation. However, it also detects policies showing little or no visible impact on repository development, and attempts to analyze the effects of different types of policies, with varied levels of success. It concludes that an open access mandate policy, by itself, will not change existing practices of scholarly self-archiving.
The incurable Dr. Vaid : transgression, nation and the crisis in postcolonial Hindi criticism

subject: Vaid, Krishna Baldev, 1927- Criticism and interpretation.
subject: Adultery in literature
subject: Nationalism and literature

description: Krishna Baldev Vaid is one of the most innovative and significant writers of Hindi fiction. He has relentlessly tested the boundaries of acceptability in Hindi fiction, and has refused to bow to pressure to conform to dominant paradigms regarding what Hindi literature should look like. The purpose of this thesis is to show that accusations that Vaid's fiction is obscene, un-Indian and lacking social engagement reflect certain anxieties regarding what constituted 'authentic' Indian literature in the postcolonial context. I argue that criticism of Vaid's more controversial work, and the subsequent relegation of his fiction to the periphery, has been the result of a set of postcolonial circumstances whereby establishing a modernity which could be asserted as both modern and Indian was considered important. In the case of Hindi literature ideas regarding what constituted 'good' Hindi fiction were heavily influenced by the social and political milieu of post-colonial India and the establishment of this uniquely Indian style of modernity. The thesis takes the themes of sexual transgression and nation as the basis for analysis of selected short fiction by Vaid to demonstrate how Vaid critiques the postcolonial discourse of the time. I argue that Vaid's fiction has been marginalized as a result of a postcolonial crisis in Hindi criticism, despite, or perhaps because of, his relentless challenging of normative discourse and his absolute refusal to conform to the boundaries dictated by his contemporaries. In the texts analysed Vaid uses rupture, dissonance, irony and wit to destabilize the predominating discourse regarding sexual transgression and nationalist sentiment. After analysis of selected fiction of Vaid based on the themes of sexual transgression and nation, the thesis proceeds to an outline of the crisis in postcolonial Hindi criticism, criticism of Vaid's work, and rebuttal from Vaid regarding the criticism he has received and the environment he considers it reflects. The main contribution of the thesis is to show that criticism of Vaid's fiction has been heavily influenced by postcolonial anxieties regarding Indianness and authenticity and that this reflects more about the environment in which he wrote than the literature itself. The evidence shows that rather than demonstrating a lack of social engagement, obscenity or undue imitation of Western models, Vaid is deeply engaged with the Indian postcolonial environment and challenges the very basis on which it was constructed.

description: Current crowding at bends of superconducting nanowire single-photon detectors is one of the main factors limiting the performance of meander-style detectors with large filling factors. In this paper, we propose a new concept to reduce influence of the current crowding effect, a so-called variable thickness SNSPD, which is composed of two regions with different thicknesses. A larger thickness of bends in comparison to the thickness of straight nanowire sections locally reduces the current density and reduces the suppression of the critical current caused by the current crowding. This allows variable thickness SNSPD to have a higher critical current, an improved detection efficiency, and decreased dark count rate in comparison with a standard uniform thickness SNSPD with an identical geometry and film quality.

description: African-ancestry (AA) participants are underrepresented in genetics research. Here, we conducted a transcriptome-wide association study (TWAS) in AA female participants to identify putative breast cancer susceptibility genes. We built genetic models to predict levels of gene expression, exon junction, and 3′ UTR alternative polyadenylation using genomic and transcriptomic data generated in normal breast tissues from 150 AA participants and then used these models to perform association analyses using genomic data from 18,034 cases and 22,104 controls. At Bonferroni-corrected P < 0.05, we identified six genes associated with breast cancer risk, including four genes not previously reported (CTD-3080P12.3, EN1, LINC01956 and NUP210L). Most of these genes showed a stronger association with risk of estrogen-receptor (ER) negative or triple-negative than ER-positive breast cancer. We also replicated the associations with 29 genes reported in previous TWAS at P < 0.05 (one-sided), providing further support for an association of these genes with breast cancer risk. Our study sheds new light on the genetic basis of breast cancer and highlights the value of conducting research in AA populations.
A phenomenological investigation of the experience of being a male counsellor relative to issues of sex and gender-roles

description: An individual's sex and associated gender-role expectations exert a primary influence on one's sense of self and nearly all the individual's interpersonal relationships. The purpose of this research project is to investigate how male counsellors experience the phenomenon of being a man, relative to issues associated with his sex and gender-role expectations, in the field of counselling. Because the emphasis is on the experience of sex and gender-role issues for male counsellors a phenomenological research method was chosen. Seven male counsellors were interviewed. The investigator conducted two interviews with each counsellor. The initial interview was designed to elicit the person's experiences of the phenomenon of being a male counsellor. After a preliminary analysis of this interview, a summary was prepared and shared with the respondent during the follow up interview. The purpose of this meeting was to verify the interpretation of the previous interview and to offer the individual an opportunity to supplement or modify his remarks. The interviews were transcribed by the investigator and analyzed using a method described by Karlsson (1993). The analysis of the data yielded three general categories of experience. They were experiences related to gender-role stereotyping, the experience of erotic feelings and the experience of being a man in a field in which they are a minority. A fourth category, which described the experience of the interviews, was included to further illuminate the results. for counsellor training, consultation The findings are discussed in light of previous research and include suggestions and further research.

description: This work is proposing and exploring the use of multichannel readout electronics, already used in quality assurance for gain uniformity studies, to measure the uniformity of the induction gap in GEM based detectors. The measurement will furthermore provide a qualification of the readout electrodes in terms of disconnected or shorted channels. The proposed method relies on the dependence on the induction gap capacitance between the readout strips and the bottom of the GEM. The measurement is obtained inducing capacitively a signal on the readout strips pulsing the bottom layer of the GEM foil. In this work, the signals are read with the analog APV25 front-end chip and the RD51 Scalable Readout System (SRS). Studies on small and large area GEM detectors, relative variations under mechanical stress, and in presence of electrical fields will be shown. Sensitivity to defects in the readout plane will be proven.

description: In recent years, many efforts have been addressed on collision avoidance of collectively moving agents. In this paper, we propose a modified version of the Vicsek model with adaptive speed, which can guarantee the absence of collisions. However, this strategy leads to an aggregated state with slowly moving agents. We therefore further introduce a certain repulsion, which results in both faster consensus and longer safe distance among agents, and thus provides a powerful mechanism for collective motions in biological and technological multi-agent systems.

description: Purpose: The purpose of this one-year longitudinal study is to examine the usage and production of educational videos on YouTubeEDU, an open, video-sharing, educational area of YouTube established in 2009 and used primarily by institutions of higher education. The aim of the YouTubeEDU project is to provide free global access to higher education videos. Analysis from a library science perspective is valuable to further development of YouTubeEDU. 

Design/methodology/approach: From  August  2010  to  July  2011,  the  top  50  video  clips  were recorded  monthly.  YouTubeEDU  loosely arranged  clips according  to the  number  of site visits  and classified them into 13 disciplines: business, education, engineering, fine arts and design, health and medicine, history, humanities, journalism and media, law, literature, mathematics, science, and social science.   Analysis   of   subject   area   and   content   correspondence   was   conducted   using YouTubeEDU-assigned, creator-defined, and study-specific attributes. 

Findings:The majority of top videos per month were university public relations materials. Overall, 40 percent of the videos were academically-oriented; English is the predominant language. Even some videos  contributed  by  non-English-speaking  higher  education  institutions  were  in  English.  The researchers also discovered misclassification of videos in several disciplines.

Research limitations/implications: Based  on  the  researchers’  monthly  observations,  future collaboration  with  the  YouTubeEDU  project  is  needed  to  collect  comprehensive  data  regarding worldwide visitor traffic and higher education video contributions.

Originality/value: Many  areas  needed  improvement  in  the  YouTubeEDU  project;  the  proposed changes would ensure that the quality and utility of videos meet the standards of higher education institutions while embracing the needs of global learners.

description: Tools to explore scientific literature are essential for scientists, especially in biomedicine, where about a million new papers are published every year. Many such tools provide users the ability to search for specific entities (e.g. proteins, diseases) by tracking their mentions in papers. PubMed, the most well known database of biomedical papers, relies on human curators to add these annotations. This can take several weeks for new papers, and not all papers get tagged. Machine learning models have been developed to facilitate the semantic indexing of scientific papers. However their performance on the more comprehensive ontologies of biomedical concepts does not reach the levels of typical entity recognition problems studied in NLP. In large part this is due to their low resources, where the ontologies are large, there is a lack of descriptive text defining most entities, and labeled data can only cover a small portion of the ontology. In this paper, we develop a new model that overcomes these challenges by (1) generalizing to entities unseen at training time, and (2) incorporating linking predictions into the mention segmentation decisions. Our approach achieves new state-of-the-art results for the UMLS ontology in both traditional recognition/linking (+8 F1 pts) as well as semantic indexing-based evaluation (+10 F1 pts).

description: Magnetic winding is a fundamental topological quantity that underpins magnetic helicity and measures the entanglement of magnetic field lines. Like magnetic helicity, magnetic winding is also an invariant of ideal magnetohydrodynamics. In this article we give a detailed description of what magnetic winding describes, how to calculate it and how to interpret it in relation to helicity. We show how magnetic winding provides a clear topological description of magnetic fields (open or closed) and we give examples to show how magnetic winding and helicity can behave differently, thus revealing different and imporant information about the underlying magnetic field.

description: Στην παρούσα διπλωματική εργασία αναλύεται ο πολιτικός λόγος του Συνασπισμού Ριζοσπαστικής Αριστεράς (ΣΥΡΙΖΑ) και διερευνάται η σχέση του με τον λαϊκισμό. Αφιερώνουμε ένα κομμάτι της εργασίας μας στον περί λαϊκισμού θεωρητικό προβληματισμό, αλλά και των εννοιών της μεταπολιτικής και της μεταδημοκρατίας. Αφού αποσαφηνίζονται έννοιες και όροι, προχωράμε στο εμπειρικό κομμάτι της εργασίας, στην ανάλυση δηλαδή του λόγου του ΣΥΡΙΖΑ. Το εμπειρικό κομμάτι πλαισιώνεται από μια συνοπτική περιγραφή της ιστορικής και τρέχουσας πολιτικοκοινωνικής συγκυρίας και των χαρακτηριστικών και παραγόντων που συνθέτουν τη σύγχρονη ελληνική μεταδημοκρατία της συναίνεσης . Αυτό που μας απασχόλησε κατά την έρευνα και συγγραφή της εργασίας δεν ήταν απλώς να εφαρμόσουμε μία θεωρία σε μια συγκεκριμένη μελέτη περίπτωσης, αλλά και να δούμε τι προσφέρει η ίδια η μελέτη της περίπτωσης στην συγκεκριμένη θεωρία και την περαιτέρω ανάπτυξη της περί λαϊκισμού προβληματικής στο σύγχρονο μετα-δημοκρατικό/μετα-πολιτικό πλαίσιο.
description: In the present essay we analyze the political discourse of the Coalition of Radical Left (SYRIZA) and we investigate its relation to populism. We proceed in our essay by dedicating a part to the concept of populism and its theoretical context and also to the concepts of post-politics and post-democracy. After clarifying concepts and terms, we move on to the empirical part of our work, the analysis of the political discourse of SYRJZA. The empirical part is framed by a concise description of the historical and sociopolitical current situation and the characteristics and factors that constitute the contemporary Greek post-democracy of consent. One of our major concerns during the research and writing process of this work was, not to simply apply a theory in a case study, but also to see what the particular case study has to offer to the particular theory and the further development of the theoretical debate about populism in the contemporary post-democratic/post-political context.

description: We study nonlinear surface modes in two-dimensional {\em anisotropic} periodic photonic lattices and demonstrate that, in a sharp contrast to one-dimensional discrete surface solitons, the mode threshold power is lower at the surface, and two-dimensional discrete solitons can be generated easier near the lattice corners and edges. We analyze the crossover between effectively one- and two-dimensional regimes of the surface-mediated beam localization in the lattice.

description: The paper "Physics without determinism: Alternative interpretations of classical physics" [Phys. Rev. A, 100:062107, Dec 2019] defines finite information quantities (FIQ). A FIQ expresses the available information about the value of a physical quantity. We show that a change in the measurement unit does not preserve the information carried by a FIQ, and therefore that the definition provided in the paper is not complete.

description: We present density-functional theory (DFT) and quantum Monte Carlo (QMC) calculations designed to resolve experimental and theoretical controversies over the optical properties of H-terminated C nanoparticles (diamondoids). The QMC results follow the trends of well-converged plane-wave DFT calculations for the size dependence of the optical gap, but they predict gaps that are 1-2 eV higher. They confirm that quantum confinement effects disappear in diamondoids larger than 1 nm, which have gaps below that of bulk diamond. Our QMC calculations predict a small exciton binding energy and a negative electron affinity (NEA) for diamondoids up to 1 nm, resulting from the delocalized nature of the lowest unoccupied molecular orbital. The NEA suggests a range of possible applications of diamondoids as low-voltage electron emitters.

description: The interest to perform laser spectroscopy in the heaviest elements arises from the strong impact of relativistic effects, electron correlations and quantum electrodynamics on their atomic structure. Once this atomic structure is well understood, laser spectroscopy also provides access to nuclear properties such as spins, mean square charge radii and electromagnetic moments in a nuclear-model independent way. This is of particular interest for the heaviest actinides around $N = 152$, a region of shell stabilized deformed nuclei. The experimental progress of laser spectroscopy in this region benefitted from continuous methodological and technical developments such as the introduction of buffer-gas-stopping techniques that enabled the access to ever more exotic nuclei far-off stability. The key challenges faced in this endeavor are small yields, nuclides with rather short half-lives and the need to search for atomic transitions in a wide spectral range guided by theoretical predictions. This paper describes the basics of the most common experimental methods and discusses selected recent results on the atomic and nuclear properties of the actinides up to nobelium where pioneering experiments were performed at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany.

Burnout among high school counsellors
Creators: name: Hooper, James T.
Publisher: name: University of British Columbia
Year: 2009

description: The psychological well-being of those who counsel adolescents is an important issue, but there has been little research on the topic. Burnout from job-related stress in the helping professions has been shown to influence negatively the professionals' job satisfaction and performance by eroding their benevolence and commitment. Three aspects of burnout — emotional exhaustion, depersonalization, and impaired personal accomplishment — were measured in this study. The High School Counsellor Questionnaire, designed for this investigation, was mailed to 265 members of the British Columbia School Counsellors Association who were working in high schools. The return rate was 61.51%; the usable N was 157. The questionnaire measured the extent of counsellors' burnout and their perception of their own social support (from family, friends and others) and administrative support (defined as support from the principal). The questionnaire also gathered information on selected personal and job characteristics of the counsellor: age, gender, counselling experience, level of education, school size, and proportion of work time devoted to counselling. Burnout levels were shown by t -tests to be low in relation to Maslach Burnout Inventory norms for mental health professionals except on the emotional exhaustion scale, where counsellors' scores were significantly higher (t =4.26; p<.001). This result may reflect the ambiguity of the counsellors' role, and ever-increasing demands on their time and energy. The association of burnout with the independent variables was explored by correlation, multiple regression analysis, t -tests, and one-way ANOVA. As expected, burnout was generally negatively correlated with perceived social and administrative support. Gender, age, education, counselling experience, and school size were not significantly associated with burnout. Percentage of work time designated for counselling was significantly (r=.26; p < 0 1 ) correlated with feelings of personal accomplishment. Future research might consider the principal's gender, and counsellors' specific work duties, case loads, paperwork burden, role ambiguity, collegial support, marital status, caregiver role at home, and coping strategies for dealing with stress. iii
